吸收塔 設備原理：對于腐蝕性氣體（如酸、堿性廢氣）的治理，目前多采用液體吸收法治理。采用液體吸收法治理該廢氣，關鍵在于凈化設備的選擇。目前，我公司自主開發(fā)了凈化效率高、操作管理簡單、使用壽命長的酸、堿性廢氣凈化工藝與設備。該工藝與產品具有結構簡單、能耗低、凈化效率高和適用范圍廣的特點，能有效去除氯化氫氣體（HCl）、氟化氫氣體（HF）、氨氣（NH3）、硫酸霧（H?SO。）、鉻酸霧（CrO，）、氰氫酸氣體（HCN）、堿蒸氣（NaOH）、硫化氫氣體（H2S）、福爾馬林（HCHO）等水溶性氣體。酸霧廢氣由風管引入凈化塔，經(jīng)過填料層，廢氣與氫氧化鈉吸收液進行氣液兩相充分接觸吸收中和反應，酸霧廢氣經(jīng)過凈化后，再經(jīng)除霧板脫水除霧后由風機排入大氣。吸收液在塔底經(jīng)水泵增壓后在塔頂噴淋而下，最后回流至塔底循環(huán)使用。凈化后的酸霧廢氣達到廣東省地方排放標準的排放要求，低于國家排放標準。
設備特點: 本設備采用填料塔對廢氣進行凈化，適合于連續(xù)和間歇排放廢氣的治理；工藝簡單，管理、操作及維修相當方便簡潔，不會對車間的生產造成任何影響；適用范圍廣，可同時凈化多種污染物；壓降較低，操作彈性大，且具有很好的除霧性能；塔體可根據(jù)實際情況采用玻璃鋼/不銹鋼/PP塑料/PVC塑料材料制作；填料采用高效、低阻的鮑爾環(huán)，可徹底地去除氣體中的異味、有害物質等。
結構形式： 本設備分單塔體和雙塔體。采用圓形塔體，用法蘭分段聯(lián)接而成。具體由貯液箱、塔體、進風段、噴淋層、填料層、旋流除霧層、出風錐帽、觀檢孔等組成。
產品用途： 本設備可廣泛應用于化工、電子、冶金、電鍍、紡織(化纖)、食品、機械制造等行業(yè)過程中排放的酸、堿性廢氣的凈化處理。如調味食品、制酸、酸洗、電鍍、電解、蓄電池等。

Absorption tower Principle of equipment： For the treatment of corrosive gases (such as acid and alkaline waste gas) liquid absorption method is mostly used at present. Using liquid absorption to treat the waste gas is the key to the selection of purification equipment. At present our company has independently developed acid and alkaline waste gas purification process and equipment with high purification efficiency simple operation and management and long service life. The process and products have the characteristics of simple structure low energy consumption high purification efficiency and wide application range can effectively remove hydrogen chloride gas (HCl) hydrogen fluoride gas (HF) ammonia gas (NH3) sulfuric acid fog (H?SO). Chromic acid mist (CrO,) cyanuric acid gas (HCN) alkali vapor (NaOH) hydrogen sulfide gas (H2S) formalin (HCHO) and other water-soluble gas. Acid fog exhaust gas is introduced into the purification tower by the air duct and through the packing layer the exhaust gas and sodium hydroxide absorption liquid are fully contacted absorbed and neutralized. After purification the acid fog exhaust gas is dehydrated and defogged by the defogging plate and discharged into the atmosphere by the fan. The absorption liquid is pressurized by the pump at the bottom of the tower and sprayed down at the top of the tower and finally returned to the bottom of the tower for recycling. The purified acid fog exhaust gas meets the emission requirements of Guangdong provincial emission standards lower than the national emission standards.
Equipment features：The equipment uses packed tower to purify the exhaust gas suitable for continuous and intermittent exhaust gas treatment; Simple process management operation and maintenance is quite convenient and simple will not cause any impact on the production of the workshop; Wide range of application can simultaneously purify a variety of pollutants; Low pressure drop large operation elasticity and has good defogging performance; The tower body can be made of FRP/stainless steel /PP plastic /PVC plastic material according to the actual situation; The packing uses the Pall ring with high efficiency and low resistance which can completely remove the odor and harmful substances in the gas
Structure form：The equipment is divided into single tower body and double tower body. The circular tower body is connected with flange segments. It is composed of liquid storage tank tower body air inlet section spray layer packing layer cyclone defogging layer air cone cap inspection hole and so on
Product use：This equipment can be widely used in chemical industry electronics metallurgy electroplating textile (chemical fiber) food machinery manufacturing and other industries in the process of acid alkaline waste gas purification treatment. Such as flavoring food acid pickling electroplating electrolysis battery and so on
