五常吸收塔

吸收塔 设备原理：对于腐蚀性气体（如酸、碱性废气）的治理，目前多采用液体吸收法治理。采用液体吸收法治理该废气，关键在于净化设备的选择。目前，我公司自主开发了净化效率高、操作管理简单、使用寿命长的酸、碱性废气净化工艺与设备。该工艺与产品具有结构简单、能耗低、净化效率高和适用范围广的特点，能有效去除氯化氢气体（HCl）、氟化氢气体（HF）、氨气（NH3）、硫酸雾（H₂SO。）、铬酸雾（CrO，）、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。酸雾废气由风管引入净化塔，经过填料层，废气与氢氧化钠吸收液进行气液两相充分接触吸收中和反应，酸雾废气经过净化后，再经除雾板脱水除雾后由风机排入大气。吸收液在塔底经水泵增压后在塔顶喷淋而下，最后回流至塔底循环使用。净化后的酸雾废气达到广东省地方排放标准的排放要求，低于国家排放标准。
设备特点: 本设备采用填料塔对废气进行净化，适合于连续和间歇排放废气的治理；工艺简单，管理、操作及维修相当方便简洁，不会对车间的生产造成任何影响；适用范围广，可同时净化多种污染物；压降较低，操作弹性大，且具有很好的除雾性能；塔体可根据实际情况采用玻璃钢/不锈钢/PP塑料/PVC塑料材料制作；填料采用高效、低阻的鲍尔环，可彻底地去除气体中的异味、有害物质等。
结构形式： 本设备分单塔体和双塔体。采用圆形塔体，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。
产品用途： 本设备可广泛应用于化工、电子、冶金、电镀、纺织(化纤)、食品、机械制造等行业过程中排放的酸、碱性废气的净化处理。如调味食品、制酸、酸洗、电镀、电解、蓄电池等。

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 (H₂SO). 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
