[0043] The working principle of the deodorizing device of the utility model applied to gas odorizing equipment is as follows:

[0044] Natural gas is a colorless and odorless gas. If residents encounter leakage when using natural gas, it will pose a safety risk, so odorants need to be added to the natural gas. Adding odorants needs to be added to the natural gas during the process of reducing the pressure of high-pressure natural gas. However, during the process of adding odorants, odorants will inevitably leak, thus affecting the surrounding environment.

[0045] In order to solve the above technical problems, the deodorizing device of the utility model applied to the gas odorizing equipment is provided with a closed cover 1, and the odorant storage tank 2, the drying tank 3 and the mixing tank 4 are all arranged in the closed cover 1. The high-pressure natural gas flows into the pressure reducing valve 5 through the high-pressure gas inlet pipe 51, and after being reduced in pressure by the pressure reducing valve 5, it flows into the mixing tank 4. The reduction value of the pressure reducing valve 5 can be adjusted by screwing the adjusting screw 52, ​​and the pressure reducing barometer 53 displays the pressure on the pressure reducing side. The reduced-pressure natural gas enters the mixing tank 4 through the second air inlet 42.

[0046] The odorant storage tank 2 stores compressed liquid odorant, and the tank pressure gauge 24 monitors the internal pressure. The odorant gas in the odorant storage tank 2 enters the drying tank 3 through the outlet valve 22, and then enters the mixing tank 4 through the first air inlet 41. The mixed pressure gauge 44 monitors the internal pressure. The mixed gas is output through the outlet pipe 43. The mixed natural gas contains odorant, which can serve as a warning in case of leakage.

[0047] The outlet valve 22 and the on-off valve 431 are both provided with an opening knob 211 , and the top of the pressure reducing valve 5 is threadedly connected with an adjusting screw 52 , and the amount of odorant added can be controlled by the opening knob 211 and the adjusting screw 52 .

[0048] The odorant gas leaked during the above-mentioned odorant addition process will be in the cover body 1, and the exhaust fan 6 will continue to exhaust air, thereby forming a negative pressure at the exhaust pipe 61, and the gas in the cover body 1 will be continuously sucked into the exhaust fan 6, and then discharged through the horizontal pipe section 62 and the vertical muffler 64. Fresh air from the outside will flow into the cover body 1 through the air inlet 13, so that the air pressure in the cover body 1 is balanced.

[0049] The metal mesh cylinder 63 is filled with purifier particles and catalyst particles. When the odorant gas flows through the inner cylinder 621, it fully contacts with the purifier particles and catalyst particles, so that it is fully and thoroughly decomposed, thereby avoiding direct discharge of the leaked odorant and affecting the surrounding environment.

[0050] The transverse pipe section 62 is fixedly connected to the air outlet of the exhaust fan 6 by two screws 622, so that it can be easily removed to replace the purifier and the catalyst.

[0051] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
