Description

Technical Field

[0001] This utility model relates to the field of waste gas pollution collection and treatment technology, specifically a waste gas collection and purification device for hazardous waste rooms. Background Technology

[0002] Hazardous waste generated by industrial enterprises is generally stored in hazardous waste temporary storage rooms. The "Standard for Pollution Control of Hazardous Waste Storage" (GB 18597-2023) clearly stipulates that "storage rooms for hazardous waste that easily generates dust, VOCs, acid mist, toxic and harmful air pollutants and irritating odor gases shall be equipped with gas collection devices and gas purification facilities." At present, most industrial enterprises have equipped their hazardous waste temporary storage rooms with exhaust gas collection and purification devices as required. Most of them use a single top-suction or side-suction collection hood to collect exhaust gas. However, the various types of hazardous waste in the temporary storage room are stored in separate areas and are relatively scattered. The form, volume and stacking height of various types of hazardous waste are different. A single collection method can easily lead to poor exhaust gas collection effect. Utility Model Content

[0003] The purpose of this invention is to provide a hazardous waste room exhaust gas collection and purification device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A hazardous waste room exhaust gas collection and purification device includes a collection pipe. One end of the collection pipe is connected to a purification device, which is connected to a fan and a high-pressure exhaust pipe. The other end of the collection pipe is sequentially connected to a collection hood 1, a movable telescopic hose 1, a collection hood 2, a movable telescopic hose 3, and a movable telescopic hose 4. The end of the movable telescopic hose 1 is connected to a collection hood 5, the end of the movable telescopic hose 2 is connected to a collection hood 5, and the end of the movable telescopic hose 3 is connected to a collection hood 6.

[0006] Furthermore, valves one, two, three, four, five, and six are respectively installed at the connection points of the collection pipe and the collection cover one, the movable telescopic hose one, the collection cover two, the movable telescopic hose two, the collection cover three, and the movable telescopic hose three.

[0007] Furthermore, the opening degree of valve one, valve two, valve three, valve four, valve five, and valve six increases sequentially.

[0008] The beneficial effects of this utility model are as follows: By combining a single collection hood with a movable telescopic hose gas collection hood, it is beneficial to collect the exhaust gas generated by hazardous waste of different heights and forms piled up in the hazardous waste room, thereby increasing the collection efficiency of various exhaust gases in the hazardous waste room. By setting valves one, two, three, four, five and six with progressively larger opening and closing degrees, the collection efficiency of exhaust gases generated in different locations in the hazardous waste room is balanced, thereby improving the overall exhaust gas collection efficiency of the hazardous waste room.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0012] like Figure 1 As shown in the embodiment of this utility model, a hazardous waste room exhaust gas collection and purification device includes a collection pipe 10. One end of the collection pipe 10 is connected to a purification device 17. The purification device 17 is connected to a fan 18 and a high-pressure exhaust pipe 19. The other end of the collection pipe 10 is sequentially connected to a collection cover 1, a movable telescopic hose 4, a collection cover 2, a movable telescopic hose 5, a collection cover 3, and a movable telescopic hose 6. The end of the movable telescopic hose 4 is connected to a collection cover 7, the end of the movable telescopic hose 5 is connected to a collection cover 8, and the end of the movable telescopic hose 6 is connected to a collection cover 9.

[0013] Furthermore, valves 11, 12, 13, 14, 15, and 16 are respectively provided at the connection points of the collection pipe 10 and the collection cover 1, the movable telescopic hose 4, the collection cover 2, the movable telescopic hose 5, the collection cover 3, and the movable telescopic hose 6.

[0014] Furthermore, the opening degree of valve 11, valve 212, valve 313, valve 414, valve 515 and valve 616 increases sequentially.

[0015] Specifically, when using this utility model, the fan 18 provides power, and the gas collection devices, from closest to furthest from the power source, are collection hood 1, movable telescopic hose 4, collection hood 2, movable telescopic hose 2, collection hood 3, and movable telescopic hose 3. The opening degrees of valves 11, 212, 313, 414, 515, and 616 increase sequentially. The exhaust gas generated by the high-height hazardous waste in the hazardous waste room is collected by collection hoods 1, 2, and 3, respectively. The collection pipe 10 enters the purification device 17. The exhaust gas generated by the hazardous waste with a low stacking height in the hazardous waste room can be collected by the collection hood 4 7, collection hood 5 8, and collection hood 6 9 through the movable telescopic hose 1 4, movable telescopic hose 2 5, and movable telescopic hose 3 6 respectively, and then enter the purification device 17 after entering the collection pipe 10. The purified exhaust gas is discharged into the atmosphere through the high exhaust pipe 19. The movable telescopic hose 1 4, movable telescopic hose 2 5, and movable telescopic hose 3 6 can be moved and extended according to the position and height of the hazardous waste stacking.

[0016] In summary, by combining a single collection hood with a movable telescopic hose gas collection hood, it is beneficial to collect exhaust gases generated by hazardous wastes of different heights, locations, and forms piled up in the hazardous waste room, thereby increasing the collection efficiency of various exhaust gases in the hazardous waste room. By setting up valves 1, 2, 3, 4, 5, and 6 with progressively larger opening degrees, the collection efficiency of exhaust gases generated at different locations in the hazardous waste room is balanced, thus improving the overall exhaust gas collection efficiency of the hazardous waste room.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
