Electromechanical engineering workshop environment-friendly dust removal device

Abstract

The invention provides an electromechanical engineering workshop environment-friendly dust removal device. According to the electromechanical engineering workshop environment-friendly dust removal device, a disc-shaped filter is used for removing dust, it can be guaranteed that the air flow is large, and therefore the dust removal efficiency is improved; a lower-layer filtering structure forms a water film structure by utilizing centrifugal force to carry out first-time filtering, and second-time filtering is carried out by utilizing an upper-layer filtering screen structure, and the humidityof exhausted air after dust removal can be guaranteed; and the lower-layer filtering structure and / or the upper-layer filter screen structure are / is cleaned by utilizing a telescopic water pipe and awater quantity controller.

Description

technical field [0001] The invention relates to the technical field of environmental protection dust removal in engineering workshops, in particular to an environmental protection dust removal device in electromechanical engineering workshops. Background technique [0002] In the process of industrial production, there is a large amount of high-temperature dusty gas that needs to be dedusted and purified. For example, the precious particulate matter contained in the smelting gas needs to be recovered under high temperature conditions, or the process requires high-temperature dedusting, and the polluted dust in the electromechanical workshop involved in the battery industry It is mainly toxic heavy metal and toxic graphite dust. In the production workshop similar to the battery industry, a dust removal system must be equipped to meet the national occupational safety and health standards and environmental protection standards, so as to prevent front-line employees from causing ...

Problems solved by technology

[0003] For example, the patent document CN105771486A describes a centrifugal dust removal device, which removes dust through the synergistic effect of centrifugal force and water flow, but the wind speed in the air intake cylinder cannot be too fast, otherwise the dust removal effect cannot meet the national occupational safety and health standards and environmental protection standards. The dust removal effect of the device is poor, the dust removal efficiency is extremely low, and the humidity of the discharged gas is too high

Patent document CN108816533A discloses a kind of air dust removal equipment, which uses multiple structures such as filter box and dust removal box to remove dust. The structure of the equipment is extremely complicated, and it is not conducive to cleaning the dust removal equipment, and the discharged air is too dry
