Dust removal device with flow equalizer

Abstract

The invention provides a dust removal device with a flow equalizer, which comprises a shell and a filter screen fixedly arranged in the shell, the filter screen is divided into a plurality of groups of air filter elements which are arranged in parallel and are used for separating air impurities by partition plates, an air inlet and an air outlet are formed at two ends of each air filter element, and flowing air enters from the air inlets and is filtered by the air filter elements; clean air is discharged through an air outlet; a flow equalizer is arranged at the end, away from the air inlet, of each air filter element and is of a tubular structure with a dust collection channel in the middle, the dust collection channel is divided into a first channel and a second channel through a baffle, an opening is formed in the baffle, and the first channel communicates with the second channel through the opening. Dust discharging outlets are formed in the two ends of the second channel, and flow guiding transition parts used for guiding dust are symmetrically distributed on the side, away from the first channel, of the flow equalizer. The air carrying dust can be discharged to the atmosphere after being equalized through the flow equalizer, and uniform flow division of the air is facilitated.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to a dust removal device with a flow equalizer. Background technique [0002] In today's society, rail transportation mainly includes diesel locomotives, electric locomotives, EMUs, high-speed rail, passenger and truck carriages, light rails, subways and other transportation carriers, and road transportation mainly includes automobiles. Their normal operation needs to inhale a large amount of air to meet the needs of combustion of internal combustion engines, heat dissipation of electronic and mechanical components, and cooling of air conditioners and other facilities. With the inhalation of a large amount of air, there are a lot of dust, catkins, plant leaves, paper scraps, plastics and other impurities in the air, which will cause wear and tear on the internal combustion engine and shorten its service life. The air channel is equipped with a dust removal device. [0003] ...

AI Technical Summary

Problems solved by technology

With the inhalation of a large amount of air, there are a lot of dust, catkins, plant leaves, paper scraps, plastics and other impurities in the air, which will cause wear and tear on the internal combustion engine and shorten its service life. The air channel is equipped with a dust removal device

[0003] The dust removal device mainly plays the role of separating the impurity air, and then obtains clean air, filters the larger particle impurities, and has a certain dust removal effect, but cannot remove small particles of dust or impurities with a small specific gravity (especially Plant fragments, catkins, poplar catkins and other floating objects), especially in the season when there is a lot of floating and sinking or catkins, a large amount of flocculent impurities enter, which is easy to cause filter blockage, reduce the service life of the air filter element, and the dust removal efficiency is low, which cannot meet the requirements. The demand for dust removal when the ventilation volume is large

[0004] The dust discharge outlet of the dust discharge channel of the existing dust removal device is often directly connected to the fan or connected to the fan through a pipe, and then the dust is drawn out by the suction of the fan. However, dust impurities are easy to accumulate near the dust discharge channel, and it takes Larger thrust requires the fan to ensure a large exhaust air volume so that the dust close to the fan can be pushed out more thoroughly. However, the dust far away from the fan is likely to remain on the dust removal device. If things go on like this, it is easy to cause the dust of the dust removal device to stick and accumulate in the dust discharge channel. Dust exhaust outlet, even cause the blockage of dust exhaust outlet, seriously affect the dust removal effect and use of the dust removal device

When encountering humid external environments such as rainwater and dew, when moisture enters the dust removal device, the dust layer on the surface of the device will turn into mud when it meets water, and the blockage of the dust discharge channel will be more serious.
