[0002] A variety of organic and inorganic waste gases are generated in the chemical production process. Directly discharging chemical waste gases into the atmosphere will cause serious environmental pollution. Under the existing technology, spray towers are often used to treat chemical waste gases. The waste gases are sucked into the spray tower and converted and discharged through neutralization reactions. The spray tower needs to be connected to different numbers of pipes according to usage requirements and waste gas composition, so as to facilitate targeted treatment of the waste gases.

[0003] The existing spray tower usually needs to use an external closed cover to close the pipe connection ports that are not connected to the pipeline, and the exhaust gas leaks when the equipment is running. Since the spray tower usually has a certain height, it is not convenient for the staff to close the pipe connection ports at a higher position, which is not convenient for use. Utility Model Content

[0029] The connection unit 200 includes a connection pipe 201 . There are multiple connection pipes 201 , which are respectively connected to the pipe connection ports. The outer wall of the connection pipe 201 is provided with a flange plate connected to the connection flange 102 .

[0030] Among them, the pipeline closing component 103 includes a mounting ring 103a, which is fixedly connected to the inner wall of the pipeline connection port, and the inner circle cross-section of the mounting ring 103a is square, and the four surfaces of the inner circle of the mounting ring 103a are rotatably connected with a closed rotating plate 103b, and the pipeline connection port is closed by the closed rotating plate 103b to prevent the chemical waste gas inside the spray tower body 101 from leaking to the outside.

[0031] Furthermore, one end of the mounting ring 103a close to the connecting pipe 201 is fixedly connected to a limiting plate 103c, and the limiting plate 103c prevents the closed rotating plate 103b from rotating outward, thereby preventing the closed rotating plate 103b from rotating too much to cause leakage, thereby improving the sealing effect.

[0032] Furthermore, a pipe plug 202 is fixedly connected to one end of the connecting pipe 201 adjacent to the pipe connecting port, and the pipe plug 202 fits with the inner circle of the limiting plate 103c. The pipe plug 202 is inserted into the pipe connecting port, thereby pushing the closed rotating plate 103b to rotate.

[0033] Furthermore, fixed closing blocks 103d are fixedly connected to the four corners of the inner circle of the mounting ring 103a. The fixed closing blocks 103d have the same cross-section as the missing parts of the two adjacent closed rotating plates 103b after closing.
