Device and method for purifying and recycling waste gas in underground tunneling working area

Abstract

The invention discloses a device and method for purifying and recycling waste gas in an underground tunneling working area. The device comprises a bottom plate, a liquid storage tank body, a liquid suction pump and a supporting frame body; the upper end of the supporting frame body is connected with a machine box cover body through a first screw, and the interior of the machine box cover body is connected with a movable box body through a driving assembly and a guiding assembly; the driving assembly comprises a dust removal motor fixed to the top of the case cover body, an air filter screen isarranged in the movable case body, one end of the movable case body is connected with an air guide funnel, the air guide funnel is communicated with an exhaust pipe at the input end of a negative pressure fan, and an exhaust pipe at the output end of the negative pressure fan extends out of the case cover body and is connected with a purification case body in the waste purification assembly. Thedevice adapts to the complex working environment of the gold mine, is low in failure rate and easy to repair and maintain, and meets the use requirements of dust removal and waste gas purification inthe actual mining production process of the gold mine.

Description

technical field [0001] The invention relates to the technical field of downhole waste gas purification, in particular to a device and method for purifying and recycling waste gas in an underground excavation work area. Background technique [0002] A mine is a general term for the wells, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Sometimes the inclined shafts, shafts, and adits in the underground development of mines are also called mines. The determination of the size of each mine field, production capacity and service life of each mine is one of the key issues that must be resolved in the design of the mine itself. [0003] At present, there are the following technical problems in the mining and production process of gold mines: 1. A large amount of dust impurities often appear in the mining and production process of gold mines, and a large amount of dust impurities and harmful gases are contained in the was...

Problems solved by technology

[0003] At present, there are the following technical problems in the mining and production process of gold mines: 1. A large amount of dust impurities often appear in the mining and production process of gold mines, and a large amount of dust impurities and harmful gases are contained in the waste gas. The dust of gold mines is mainly composed of ore In the process of gold mining, dust is mainly produced in the process of drilling and blasting, crushing, screening and belt transmission. If underground workers inhale this kind of dust for a long time, it will cause harm to the human body. Therefore, it is necessary to use the corresponding dust removal device to deal with the dust. However, the existing dust removal device is difficult to maintain, has a single function, and cannot cope with the complex working environment in the gold mining production process. In addition, the gold mine dust often contains a large amount of Heavy metal dust particles often cause irreversible damage to the respiratory tract of the staff, seriously affecting the health and work efficiency of the staff; 2. In the process of dust treatment by the dust removal device, the function is relatively single, which cannot solve the problem of underground drying of gold mines. In the dusty environment, the gold mine dust tends to adhere strongly to the filter net, resulting in the filter function gradually reducing or even disappearing as the production process continues, and it is impossible to reduce the dust content in the gold mine; 3. Heavy metal dust in the entire gold mine During the dust removal process of the particles, the dust is not collected effectively, which leads to the secondary flying of the heavy metal dust particles of the gold mine, thereby polluting the environment again; 4. The overall cost of the existing device is expensive and the failure rate is high. During use, Due to the complex terrain environment of the gold mine, it is difficult for some maintenance parts to be transported to the inside of the mine in time, resulting in the stagnation and shutdown of the dust removal work. Moreover, as the mine excavation continues, the heavy metal dust particles of the gold mine are also continuously generated. , the existing dust removal devices on the market often break down in this environment, and the maintenance is difficult, which is difficult to meet the actual mining and production process of gold mines; The health of personnel will have a long-term toxic effect. The exhaust gas that has not been dedusted and purified cannot meet the needs of the staff, causing difficulty in breathing, and these gases continue to viciously cycle in the underground environment, and the heavy metal dust particles of gold mines are also constantly accumulating. Aggravate, therefore, contribute to the continuous deterioration of the working environment
