该排风设备是用于从磷化的盐酸蒸气管道中抽出酸洗池上的空气。被抽出的空气进入地下道,从地下道经过直径为1400毫米的洞口进入排气室。在排气室一端的墙上,有一只带管子的孔。这只管子与ц4—70№16型号的排风扇弯曲连接。在距离地下道出口2.5米的地方,安装六台用四只喷咀喷水的过滤器,喷咀和循环水系统相连接。当喷洒的水中HCl的浓度达到2—3克/升时,最后把水抽出中和。
This venting device is used to withdraw the air from the pickling tank from the phosphated hydrochloric acid vapor line. The extracted air enters the underpass and enters the exhaust chamber from the underpass through a hole of 1,400 mm in diameter. On the wall at the end of the exhaust chamber there is a hole with a tube. This pipe is connected with the ц4-70№16 fan. In the distance of 2.5 meters from the exit of the underground road, six filters with four nozzles are installed. The nozzles are connected with the circulating water system. When the concentration of HCl in the sprayed water reaches 2-3 g / l, the water is finally extracted and neutralized.
