specific Embodiment 1
[0016] like figure 1 As shown, the present invention provides a dual-purpose neutralization tower for chlorine waste gas treatment and chlorine leakage emergency treatment, which includes a water tower 5, a breathable and acid-resistant first buffer layer 4 is installed in the middle of the water tower 5, and the top of the water tower 5 is equipped with The first nozzle 6, the first nozzle 6 is connected to the water pump 10, the inlet of the water pump 10 is the water inlet 9; the bottom of the water tower 5 is connected to the waste liquid pool 17 and the waste gas inlet 11, and the top of the water tower 5 is connected to the exhaust fan 8; between the water tower 5 and the waste gas inlet 11 A second shut-off valve 12 is installed; the neutralization tower also includes a lye tower, a breathable, acid-resistant and alkali-resistant second buffer layer 14 is installed in the middle of the lye tower 1, and a second nozzle 2 is installed on the top of the lye tower 1 , the s...
specific Embodiment 2
[0018] On the basis of specific embodiment one, it can be improved that an adsorption tail gas treatment device 7 is also installed at the outlet of the exhaust fan 8, and the lye tower 1 and the water tower 5 handle most of the tail gas, but because chlorine is highly toxic Substances also need double protection to completely reduce the concentration of chlorine tail gas below the safe concentration. The rear end of the tail gas treatment device 7 is also provided with a chlorine gas detector, which detects the concentration of chlorine gas in the treated tail gas in real time, and if it exceeds, an alarm will be issued to check whether there is an equipment failure.
specific Embodiment 3
[0019] On the basis of the first embodiment, it can be improved that the first shut-off valve 3 , the second shut-off valve 12 and the third shut-off valve 13 are pneumatic or electric valves. After the second cut-off valve 12 is opened, the first cut-off valve 3 and the third cut-off valve 13 are closed in linkage, and after the second cut-off valve 12 is closed, the first cut-off valve 3 and the third cut-off valve 13 are opened in linkage. After the improvement, remote switching can be realized, or the opening and closing of the valve can be linked by the gas detector.
[0020] Working principle: exhaust fan 8 is always on, close the first stop valve 3 and third stop valve 13 in daily operation, open the second stop valve 12, the exhaust gas in daily operation can be absorbed through the water tower 5; open in case of emergency leakage The first shut-off valve 3 and the third shut-off valve 13 close the second shut-off valve 12, and if the chlorine gas content is high, it i...
