wp-block-column-is-layout-flow\"><h3>Product Overview<\/h3>\n<p>The EXW series horizontal spray scrubber operates on the same fundamental principle as a vertical spray scrubber and is designed for treating most water-soluble pollutants, acidic exhaust gases and alkaline exhaust gases.<\/p>\n<p>In addition to removing water-soluble gaseous pollutants, the system can also capture particulate matter larger than the micron level. Its basic treatment principle is to bring contaminated gas into full contact with a liquid absorbent, transfer pollutants from the gas phase into the liquid phase, and then separate the purified gas from the contaminated liquid.<\/p>\n<p>Under controlled temperature and pressure conditions, the circulating spray system delivers the absorption liquid through high-pressure nozzles. High-efficiency packing material promotes atomization and increases the gas-liquid contact area.<\/p>\n<p>At the beginning of gas-liquid contact, pollutant dissolution and absorption dominate the mass-transfer process. As the pollutant concentration in the absorption liquid increases, the absorption rate gradually decreases while the desorption rate increases.<\/p>\n<p>When the absorption and desorption rates become equal, the system reaches gas-liquid phase equilibrium and the net dissolution process stops. At this stage, the saturated washing liquid should be replaced or treated. Otherwise, the absorbed pollutants may escape from the liquid phase and return to the gas phase.<\/p>\n<p>For acidic or alkaline exhaust gas treatment, the scrubber can be equipped with an automatic chemical dosing system. Sulfuric acid, alkaline solution or another suitable reagent is automatically introduced into the circulating liquid to react rapidly with the target pollutants and improve neutralization efficiency.<\/p>\n<p><!-- Image 2: Working Principle or Internal Structure Diagram --><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1016 size-full\" src=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311.png\" alt=\"Horizontal Spray Scrubber Working Principle\" width=\"1286\" height=\"1223\" srcset=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311.png 1286w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311-300x285.png 300w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311-1024x974.png 1024w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311-768x730.png 768w\" sizes=\"auto, (max-width: 1286px) 100vw, 1286px\" \/><\/p>\n<h3>Working Principle<\/h3>\n<p>The EXW horizontal spray scrubber mainly consists of the scrubber body, spray sections, mist elimination section, circulating-water piping and circulating pump.<\/p>\n<p>The spray sections use spiral nozzles and high-efficiency packing materials such as Pall rings. Transparent inspection windows can be installed to allow convenient observation of internal operating conditions.<\/p>\n<p>The mist elimination section can use swirl plates, Raschig rings or other demisting media to remove entrained water droplets from the treated gas.<\/p>\n<p>The circulating pump can be selected from corrosion-resistant plastic pumps or stainless steel centrifugal pumps according to the liquid composition and operating conditions.<\/p>\n<p>Other components, including plastic piping, valves, support frames, maintenance ladders and inlet ducts, can be customized according to project requirements.<\/p>\n<p>During operation, contaminated gas enters the scrubber tangentially through the lower inlet. Driven by the ventilation fan, the gas rapidly fills the inlet chamber and then passes evenly through the flow-distribution section.<\/p>\n<p>Inside the spray zone, the absorption liquid is atomized through evenly arranged nozzles. Fine droplets fully mix and contact the contaminated gas, allowing soluble pollutants and acidic or alkaline components to transfer into the liquid and undergo chemical reactions.<\/p>\n<p>The treated gas then passes through the mist eliminator, where entrained liquid droplets are removed. The purified gas exits through the upper discharge duct and is released through the exhaust stack after meeting the applicable emission requirements.<\/p>\n<h3>Treatment Process<\/h3>\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\n<tbody>\n<tr>\n<td><strong>Process Stage<\/strong><\/td>\n<td><strong>Description<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>1.

Driven by the ventilation fan, the gas rapidly fills the inlet section and then rises evenly through the flow distribution section.<br \/>\nInside the spray section, the absorption liquid is sprayed at high speed through evenly distributed nozzles, forming fine droplets that fully mix and come into contact with the gas. Chemical reactions continue during this gas-liquid contact process, allowing pollutants to be absorbed and removed.<br \/>\nAfter treatment, the purified gas exits through the exhaust duct at the top of the scrubber and is discharged through the stack in compliance with emission requirements.<\/p>\n\n\n\n\n<p class=\"has-monte-grey-color has-text-color has-link-color wp-elements-434dba10dab9870bd3f4392b641f9397 wp-block-paragraph\"><\/p>\n\n\n\n<section class=\"wp-block-themepark-block-themepark-listbox thempark-block themepark_listbox\" style=\"padding-top:15px;text-align:left;\"><ul class=\"themepark_listbox_list\" style=\"padding-left:0%;padding-right:2%;\"><li style=\"color:#000000;font-size:18px;line-height:28px;margin-bottom:9px;padding-left:33px;\"><i class=\"fas fa-envelope\" style=\"color:#009aab;line-height:28px\"><\/i><span>esairsuzhou@vip.163.com<\/span><\/li><li style=\"color:#000000;font-size:18px;line-height:28px;margin-bottom:9px;padding-left:33px;\"><i class=\"fas fa-phone\" style=\"color:#009aab;line-height:28px\"><\/i><span>0512-57398857<\/span><\/li><li style=\"color:#000000;font-size:18px;line-height:28px;margin-bottom:9px;padding-left:33px;\"><i class=\"fas fa-phone\" style=\"color:#009aab;line-height:28px\"><\/i><span>13776305335  M.

Overview<\/h3>\r\nThe EXW series horizontal spray scrubber operates on the same fundamental principle as a vertical spray scrubber and is designed for treating most water-soluble pollutants, acidic exhaust gases and alkaline exhaust gases.\r\n\r\nIn addition to removing water-soluble gaseous pollutants, the system can also capture particulate matter larger than the micron level. Its basic treatment principle is to bring contaminated gas into full contact with a liquid absorbent, transfer pollutants from the gas phase into the liquid phase, and then separate the purified gas from the contaminated liquid.\r\n\r\nUnder controlled temperature and pressure conditions, the circulating spray system delivers the absorption liquid through high-pressure nozzles. High-efficiency packing material promotes atomization and increases the gas-liquid contact area.\r\n\r\nAt the beginning of gas-liquid contact, pollutant dissolution and absorption dominate the mass-transfer process. As the pollutant concentration in the absorption liquid increases, the absorption rate gradually decreases while the desorption rate increases.\r\n\r\nWhen the absorption and desorption rates become equal, the system reaches gas-liquid phase equilibrium and the net dissolution process stops. At this stage, the saturated washing liquid should be replaced or treated. Otherwise, the absorbed pollutants may escape from the liquid phase and return to the gas phase.\r\n\r\nFor acidic or alkaline exhaust gas treatment, the scrubber can be equipped with an automatic chemical dosing system. Sulfuric acid, alkaline solution or another suitable reagent is automatically introduced into the circulating liquid to react rapidly with the target pollutants and improve neutralization efficiency.\r\n\r\n<!-- Image 2: Working Principle or Internal Structure Diagram -->\r\n\r\n<img class=\"aligncenter wp-image-1016 size-full\" src=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/57f47dc4-41c0-48c5-977b-591478b7c311.png\" alt=\"Horizontal Spray Scrubber Working Principle\" width=\"1286\" height=\"1223\" \/>\r\n<h3>Working Principle<\/h3>\r\nThe EXW horizontal spray scrubber mainly consists of the scrubber body, spray sections, mist elimination section, circulating-water piping and circulating pump.\r\n\r\nThe spray sections use spiral nozzles and high-efficiency packing materials such as Pall rings. Transparent inspection windows can be installed to allow convenient observation of internal operating conditions.\r\n\r\nThe mist elimination section can use swirl plates, Raschig rings or other demisting media to remove entrained water droplets from the treated gas.\r\n\r\nThe circulating pump can be selected from corrosion-resistant plastic pumps or stainless steel centrifugal pumps according to the liquid composition and operating conditions.\r\n\r\nOther components, including plastic piping, valves, support frames, maintenance ladders and inlet ducts, can be customized according to project requirements.\r\n\r\nDuring operation, contaminated gas enters the scrubber tangentially through the lower inlet. Driven by the ventilation fan, the gas rapidly fills the inlet chamber and then passes evenly through the flow-distribution section.\r\n\r\nInside the spray zone, the absorption liquid is atomized through evenly arranged nozzles. Fine droplets fully mix and contact the contaminated gas, allowing soluble pollutants and acidic or alkaline components to transfer into the liquid and undergo chemical reactions.\r\n\r\nThe treated gas then passes through the mist eliminator, where entrained liquid droplets are removed. The purified gas exits through the upper discharge duct and is released through the exhaust stack after meeting the applicable emission requirements.\r\n<h3>Treatment Process<\/h3>\r\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\r\n<tbody>\r\n<tr>\r\n<td><strong>Process Stage<\/strong><\/td>\r\n<td><strong>Description<\/strong><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><strong>1.

It combines spray absorption, chemical neutralization, packing mass transfer and mist elimination to remove gaseous pollutants and particulate matter. Available in PP, FRP, Q235B carbon steel and SUS304 stainless steel, the system is suitable for chemical, pharmaceutical, electronics, metal processing and industrial furnace applications.\r\n<\/em><\/p>\";s:6:\"ector1\";s:864:\"The EXW series horizontal spray scrubber operates on the same basic principle as a vertical spray scrubber and is classified as a two-stage counter-current absorption tower.\r\nContaminated gas enters the purification unit tangentially through the lower air inlet. Driven by the ventilation fan, the gas rapidly fills the inlet section and then rises evenly through the flow distribution section.\r\nInside the spray section, the absorption liquid is sprayed at high speed through evenly distributed nozzles, forming fine droplets that fully mix and come into contact with the gas. Chemical reactions continue during this gas-liquid contact process, allowing pollutants to be absorbed and removed.\r\nAfter treatment, the purified gas exits through the exhaust duct at the top of the scrubber and is discharged through the stack in compliance with emission requirements.\";s:7:\"slideb2\";s:19:\"1013,1017,1018,1019\";}"],"_thumbnail_id":["1013"],"_autoid":["1"],"_blocktemname":["\u4ea7\u54c1\u8be6\u60c5\u6a21\u677f"]},"medium_url":"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/1765266018307739-300x225.jpg","thumbnail_url":"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/1765266018307739-150x150.jpg","full_url":"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/1765266018307739.jpg","_links":{"self":[{"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/posts\/1014","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/comments?post=1014"}],"version-history":[{"count":1,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/posts\/1014\/revisions"}],"predecessor-version":[{"id":1020,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/posts\/1014\/revisions\/1020"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/media\/1013"}],"wp:attachment":[{"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/media?parent=1014"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/categories?post=1014"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.esair-equip.com\/fr\/wp-json\/wp\/v2\/tags?post=1014"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
