Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and more specifically, it relates to a multi-stage filtration device for treating radioactive waste gas. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during production and daily life, especially waste gas generated from chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries, as well as domestic waste gas. The emitted waste gas has a strong odor, seriously pollutes the environment and affects human health. Waste gas contains many types of pollutants with very complex physical and chemical properties and varying degrees of toxicity. Waste gas emitted from fuel combustion contains sulfur dioxide, nitrogen oxides, hydrocarbons, etc.

[0003] Radioactive waste gas needs to be treated when it is discharged. Traditional waste gas treatment equipment often uses a spray structure to treat waste gas. However, existing devices lack a dust filtration mechanism, which causes dust to damage the water pump when the spray structure is in use. To solve the above problems, we have introduced the following device. Utility Model Content

Then, the staff controls the operation of the vacuum pump 6 through the control switch 21, thereby drawing the radioactive waste gas into the housing 2. With the cooperation of the filter bags 4, it is convenient for the staff to filter the dust carried in the radioactive waste gas, avoiding the blockage and damage caused by the water pump 12 used by the staff when treating the radioactive waste gas.

[0019] Specifically, a water pump 12 is fixedly connected inside the water storage tank 11, and a liquid guide pipe 13 is fixedly connected to the upper surface of the water pump 12.

[0020] By adopting the above technical solution, this multi-stage filtration device for radioactive waste gas treatment, by setting up a diversion conduit 14, a spray head 15 and a water pump 12, when the staff needs to spray the filtered radioactive waste gas, the staff only needs to control the operation of the water pump 12 through the control switch 21, so that the solution in the water collection tank 11 can be transferred to the diversion conduit 14 through the liquid guide pipe 13, and finally sprayed out through the spray head 15, thereby achieving the purpose of treating the radioactive waste gas. Finally, the treated gas can be discharged through the exhaust pipe 16.

[0021] Specifically, the adjustment mechanism 8 includes a connecting plate 801, which is fixedly connected to the side of the cover 7.

If the filter is blocked or damaged, when the staff needs to spray the filtered radioactive waste gas, the staff only needs to control the water pump 12 through the control switch 21 to transfer the solution in the water collection tank 11 to the diversion pipe 14 through the liquid guide pipe 13, and finally spray it out through the spray head 15, thereby achieving the purpose of treating the radioactive waste gas. The treated gas can be discharged through the exhaust pipe 16. When the staff needs to centrally treat the dust, the staff only needs to rotate the turntable 804 to drive the threaded column 805 to rotate.
