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...

Abstract

The invention discloses a chlorine waste gas treatment and chlorine leakage emergency treatment dual-purpose neutralizing tower which comprises a water tower. A breathable acid-resistant first buffering layer is installed in the middle in the water tower. A first spraying nozzle is arranged on the top of the water tower and connected with a water pump. The inlet of the water pump is a water inlet.The bottom of the water tower is connected with a waste liquid pond and a waste gas inlet. The top of the water tower is connected with an exhaust fan. A second stop valve is installed between the water tower and the waste gas inlet. The neutralizing tower further comprises an alkali liquor tower. A breathable acid-resistant alkali-resistant second buffering layer is installed in the middle in the alkali liquor tower. A second spraying nozzle is arranged on the top of the alkali liquor tower and connected with an alkali liquor pump which is connected with an alkali liquor pond. The bottom ofthe alkali liquor tower is connected with the waste liquid pond. The top of the alkali liquor tower is connected with the lower side of the first buffering layer of the water tower. A first stop valveis installed between the alkali liquor tower and the water tower. The lower side of the second buffering layer of the alkali liquor tower is connected with the waste gas inlet. The neutralizing towerhas the advantages of being capable of processing tail gas generated in daily operation and also capable of being used for emergency leakage treatment.

Description

technical field [0001] The invention relates to the field of waste gas treatment devices, in particular to a dual-purpose neutralization tower for chlorine gas waste gas treatment and chlorine gas leakage emergency treatment. Background technique [0002] Chlorine is a special gas commonly used in the semiconductor industry and is mainly used for etching semiconductor materials. However, the nature of chlorine gas is highly toxic, corrosive and oxidizing, so the treatment of chlorine gas tail gas is also very strict. At present, the main adsorption agent for chlorine gas tail gas treatment needs to judge whether the agent has deteriorated according to its color. At present, most of the agents are imported and the price is expensive. In addition, the emergency leakage of chlorine gas is another system, and the exhaust gas is drawn out by the exhaust fan to be neutralized by spraying lye. Contents of the invention [0003] In order to solve the above problems, the present ...
