BJT/PP/PVC系列酸雾净化塔
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(HCI)、氟化氢气体(HF)、氨气(NH)、硫酸雾(HsO。)、铬酸雾(CrO。)、氰氢酸气体(HCN)、碱蒸气(NaOH)、硫化氢气体(HS)、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

BJT/PP/PVC series acid fog purification tower
For the treatment of corrosive gases (such as acid and alkaline waste gas), the liquid absorption method is currently used for treatment. The key to the treatment of this waste gas by the liquid absorption method lies in the choice of purification equipment. At present, our company has independently developed acid and alkaline waste gas purification processes and equipment with high purification efficiency, simple operation and management, and long service life. 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 (HCI), hydrogen fluoride gas (HF), ammonia (NH), sulfuric acid mist (HsO.), Chromic acid mist (CrO.), hydrocyanic acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (HS), formalin (HCHO) and other water-soluble gases.
The acid mist exhaust gas is introduced into the purification tower through the air pipe, and passes through the packing layer. The exhaust gas and the sodium hydroxide absorption liquid undergo gas-liquid two-phase full contact absorption and neutralization reaction. After the acid mist exhaust gas is purified, it is dehydrated and defogged by a demister plate. The fan is discharged into the atmosphere. The absorption liquid is sprayed down at the top of the tower after being pressurized by a water pump at the bottom of the tower, and finally returned to the bottom of the tower for recycling. The purified acid mist exhaust gas meets the emission requirements of the local emission standards of Guangdong Province, which is lower than the national emission standards
