Description

Technical Field

[0001] The present invention belongs to the technical field of gas treatment, and particularly relates to a gas treatment device for an underground coal mine electrical control room. Background Art

[0002] Coal mine electrical equipment in the underground coal mine electrical control room is the management core of the entire coal mine. The safe and reliable operation of its underground electrical equipment is not only related to the safe production of the mine, but also related to the life safety of the staff. The occurrence of faults and the damage of electrical equipment will affect the output. In severe cases, it may even cause a series of serious industrial accidents such as gas explosions. It is of great significance to establish a systematic safety management measure for coal mine electrical equipment to minimize or even avoid the occurrence of major safety accidents in coal mine shafts. During the coal mine production process, there are many mechanical equipment, the working surface conditions are complex, the underground roadway space is narrow, the working conditions are harsh, and there are various uncertain factors in the working environment, so various safety accidents are likely to occur underground. Coal mine electrical equipment accidents are extremely important factors restricting coal mine production and development. They will not only cause harm to equipment and personnel, but also are very likely to be the main factors inducing major accidents such as coal dust and gas explosions; at the same time, the gas underground is very turbid, and its air contains not only combustible gases, but also a small amount of oil mist, water vapor and a large amount of dust. These dirty airs not only harm the workers' bodies, but also harm the coal mine electrical equipment underground. If not purified, it will increase the frequency of electrical equipment accidents. The existing gas treatment devices for underground coal mine electrical control rooms have the following defects: the filtration system is often blocked by dust. There is a lot of dust underground, which often blocks the filter cotton. Replacing the filter cotton requires disassembling the device, which is time-consuming and laborious; 2. The existing device only has a dust removal function and cannot detect and control gases in different directions. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a gas treatment device for an underground coal mine electrical control room, which solves at least part of the above technical problems.

[0004] The technical solution adopted by the present invention is as follows: A gas treatment device for an underground coal mine electrical control room, including a support plate for support and fixation. There are two groups of the support plates, namely a first support plate and a second support plate. An fixing plate is installed on the upper walls of the first support plate and the second support plate. A plurality of groups of gas treatment devices for gas treatment are evenly installed on the fixing plate at equal intervals in a ring shape.
