[0021] Refer to the attached Figures 1 to 2As shown, the embodiment of the present application provides a chlorine dioxide generator 1 safety pressure relief and harmless collection and treatment device, including a chlorine dioxide generator 1 and a contact disinfection pool 2. The chlorine dioxide generator 1 is equipped with an explosion-proof valve 101. There are three explosion-proof valves 101 in total. They are valves provided by the chlorine dioxide generator 1. When the chlorine dioxide generator 1 is damaged, blocked or due to other reasons, resulting in the inability to discharge internal gas, the valve cover of the explosion-proof valve 101 will be flushed open to avoid bursting. After the valve cover of each explosion-proof valve 101 is removed, an external thread is provided at the position for connecting the valve cover, which is used to install a flange by threaded connection. A connecting pipe is installed on each flange, and the three connecting pipes are connected to a pressure relief pipe 3. The pressure relief pipe 3 leads to the contact disinfection pool 2. The pressure relief pipe 3 is located at one end of the contact disinfection pool 2 and is provided with a spray system 5. The chlorine dioxide gas after the pressure is released from the explosion-proof valve 101 flows into the contact disinfection pool 2 through the pressure relief pipe 3, is diluted by the spray system 5, and is absorbed and processed by the contact disinfection pool 2. Chemical substances (such as sodium hydroxide) can be added to the contact disinfection pool 2 to react with chlorine dioxide to generate salt and water, thereby achieving the purpose of absorbing and treating chlorine dioxide. At the same time, a plurality of highly elastic explosion-proof airbags 4 are arranged on the pressure relief pipe 3. Since a large amount of high-pressure gas flows into the pressure relief pipe 3 at the moment the explosion-proof valve 101 is opened, in order to prevent the pressure relief pipe 3 from bursting due to high pressure, a plurality of highly elastic explosion-proof airbags 4 are arranged. When the high-pressure gas passes through the pressure relief pipe 3, the expansion of the highly elastic explosion-proof airbags 4 can be used to relieve the air pressure in the pressure relief pipe 3, thereby achieving the effect of reducing pressure and preventing explosions.

[0022] In the above, the high elastic explosion-proof airbag 4 belongs to the existing conventional technology, and the model can be a GC-DN800 natural rubber pressure-resistant explosion-proof pipeline airbag.

[0023] In this embodiment, see Figure 2 and Figure 3As shown in the figure, the spraying system 5 includes a spraying tower 501. The spraying tower 501 is located inside the contact disinfection tank 2 and above the liquid level of the disinfectant solution. A first pipeline hole is provided at the top of the contact disinfection tank 2. The pressure relief pipe 3 enters the inside of the contact disinfection tank 2 from the first pipeline hole and is connected to the spraying tower 501. After the pressure relief pipe 3 enters the contact disinfection tank 2, the first pipeline hole is sealed with sealant to prevent gas leakage. The pressure relief pipe 3 enters the inside of the spraying tower 501 from the top of the spraying tower 501. The bottom of the spraying tower 501 is designed with an open mouth. A first spraying ring pipe 502 is installed around the air outlet of the pressure relief pipe 3 on the inner side of the top of the spraying tower 501. A plurality of first spray heads 503 are evenly distributed on the first spraying ring pipe 502. After the pressure-relieved chlorine dioxide gas enters the spraying tower 501, dilution operation can be carried out by using the first spraying ring pipe 502. At the same time, a second spraying ring pipe 504 is also provided on the outer periphery of the bottom of the spraying tower 501. A plurality of second spray heads 505 are evenly distributed on the second spraying ring pipe 504. The second spray heads spray towards the liquid level, which also has the effect of dilution. The diluted chlorine dioxide gas can be absorbed and treated in the contact disinfection tank 2. Of course, the contact disinfection tank 2 has circulating inlet and outlet pipelines to maintain the treatment capacity and normal pressure of the contact disinfection tank 2.

[0024] In the above, the contact disinfection tank 2 includes a box body. A spraying water tank 6 is provided at the top of the box body. A water pump 8 is provided beside the spraying water tank 6. The water pump 8 is connected to a water supply pipe 7. A second pipeline hole is opened at the top of the box body. The water supply pipe 7 enters the contact disinfection tank 2 from the second pipeline hole. Both the first spraying ring pipe 502 and the second spraying ring pipe 504 are connected to the water supply pipe 7. After the water supply pipe 7 enters the contact disinfection tank 2, the second pipeline hole is sealed with sealant to avoid leakage of chlorine dioxide gas.

[0025] In summary, a safety pressure relief and harmless collection and treatment device for a chlorine dioxide generator 1 provided by an embodiment of the present application, by installing a pressure relief pipe 3 on the explosion-proof valve 101 of the existing chlorine dioxide generator 1, using the pressure relief pipe 3 to dilute the chlorine dioxide gas after explosion-proof pressure relief through the spraying system 5, and then using the contact disinfection tank 2 to absorb and treat the chlorine dioxide, thereby avoiding the overflow of harmful gases.

[0026] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
