BJT/PP/PVC系列酸霧凈化塔 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(HCI)、氣體(HF)、氨氣(NH)、硫酸霧(HsO。)、鉻酸霧(CrO。)、氰氫酸氣體(HCN)、堿蒸氣(NaOH)、硫化氫氣體(HS)、福爾馬林(HCHO)等水溶性氣體。
酸霧廢氣由風管引入凈化塔，經過填料層，廢氣與*吸收液進行氣液兩相充分接觸吸收中和反應，酸霧廢氣經過凈化后，再經除霧板脫水除霧后由風機排入大氣。吸收液在塔底經水泵增壓后在塔頂噴淋而下，最后回流至塔底循環使用。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
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
