酸雾净化塔设备原理

酸雾净化塔设备原理和***色

 

设备***色:本设备选用填料塔对废气进行净化，适合于接连和间歇排放废气的处理；工艺简略，处理、操作及修理恰当便当简练，不会对车间的出产形成任何影响；适用范围广，可一同净化多种污染物；

　　设备原理：酸雾净化塔关于腐蚀性气体（如酸、碱性废气）的处理，现在多选用液体吸收法处理。选用液体吸收法处理该废气，关键在于净化设备的选择。现在，我公司自主开发了净化效率高、操作处理简略、运用寿命长的酸、碱性废气净化工艺与设备。该工艺与产品具有结构简略、能耗低、净化效率高和适用范围广的***色，能有用去除氯化氢气体（HCl）、氟化氢气体（HF）、氨气（NH3）、硫酸雾（H2SO4）、铬酸雾（CrO3）、氰氢酸气体（HCN）、碱蒸气（NaOH）、硫化氢气体（H2S）、福尔马林（HCHO）等水溶性气体。酸雾废气由风管引进净化塔，通过填料层，废气与氢氧化钠吸收液进行气液两相充分触摸吸收中和反响，酸雾废气通过净化后，再经除雾板脱水除雾后由风机排入***气。吸收液在塔底经水泵增压后在塔***喷淋而下，终究回流至塔底循环运用。净化后的酸雾废气达到广东省当地排放规范的排放要求，低于***家排放规范。

设备***色:本设备选用填料塔对废气进行净化，适合于接连和间歇排放废气的处理；工艺简略，处理、操作及修理恰当便当简练，不会对车间的出产形成任何影响；适用范围广，可一同净化多种污染物；压降较低，操作弹性***，且具有很***的除雾功能；塔体可根据实际情况选用FRP/PP/PVC等材料制造；填料选用高效、低阻的鲍尔环，可彻底地去除气体中的异味、有害物质等。

结构方式：本设备分单塔体和双塔体。选用圆形塔体，用法兰分段联接而成。具体由贮液箱、塔体、进风段、喷淋层、填料层、旋流除雾层、出风锥帽、观检孔等组成。

使用场合：本工艺和设备可广泛使用于化工、电子、冶金、电镀、纺织(化纤)、食物、机械制造等工作过程中排放的酸、碱性废气的净化处理。如调味食物、制酸、酸洗、电镀、电解、蓄电池等。

Equipment principle: BJT acid mist purification tower for corrosive gases (such as acid, alkaline exhaust gas) treatment, the current use of liquid absorption treatment. The use of liquid absorption treatment of the exhaust gas, the key lies in the choice of purification equipment. At present, the company independently developed a purification efficiency, operation and management simple, long service life of acid and alkaline exhaust gas purification technology and equipment. The process and product have the characteristics of simple structure, low energy consumption, high purification efficiency and wide application range, and can effectively remove hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid mist (H2SO4) Water-soluble gas such as acid mist (CrO3), hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S) and formalin (HCHO). Acid mist exhaust gas from the duct into the purification tower, through the filler layer, the exhaust gas and sodium hydroxide absorption liquid for gas-liquid two-phase full absorption and neutralization reaction, acid mist exhaust gas purification, and then by the defogging plate dewatering Fan into the atmosphere. Absorbent liquid in the bottom of the tower pressurized by the pump after the spray in the top of the tower, and finally back to the bottom of recycling. The purified acid mist exhaust gas meets the emission standard of Guangdong Province, which is lower than the national emission standard.
