Humidifying dust removal and purification device for road sweeping machine

Abstract

The invention relates to a humidifying dust removal and purification device for a road sweeping machine. The device is of a closed tank body and comprises air inlet, an air outlet, a sprinkling dedusting chamber, three gas washing chambers, a flow guiding plate, a sprinkler pipe, an atomizer, a dewatering chamber, a water storage tank, a mud pump and a splash-proof grille. Through arranging the flow guiding plate, the sprinkling dedusting chamber is divided into a plurality of sprinkling dedusting zones, a direction is changed continuously when an air-water mixture passes through the device, impact wind is scattered repeatedly, and dust is separated from water and falls into the water storage tank due to each direction change of the air-water mixture, so as to achieve the aim of dedusting.The air-water mixture simultaneously passes through the three gas washing chambers, thus, air flow is further decelerated and depressurized, and the dust further settles down and falls into the waterstorage tank under the condition of speed and pressure changing. The air flow subjected to progressive sprinkling purification is subjected to progressive dewatering and drying by the dewatering chamber, and finally, the air flow is directly exhausted as standard-reaching gas.

Description

Technical field [0001] The invention belongs to the technical field of road cleaning machinery, and mainly relates to how to remove dust and purify after the road cleaning machinery absorbs and collect road garbage through a negative pressure device, and then make the gas to meet the standard and directly empty; specifically relates to a road cleaning machinery used for road cleaning The humidification and dust removal purification device. Background technique [0002] At present, road cleaning machinery has a pure suction type and an integrated washing and sweeping type. The structure principle of the pure suction type is to suck the road waste into the negative pressure box through the suction cup device. The negative pressure box is a closed space. A large mesh coarse filter screen is installed on the upper part of the negative pressure box for primary filtration, and then the dust-containing gas is introduced into a purification device equipped with a filter barrel, and is di...

AI Technical Summary

Problems solved by technology

The problem is that after a period of use, the filter barrel is clogged and the suction power drops

The filter barrel purification device in the original design of such models cannot be used, and can only be removed

This causes the gas discharged from the negative pressure box to be emptied directly without purification and drying treatment, and there is also secondary pollution

At the same time, there is also a large amount of water, and it cannot be used in the north during the freezing period in winter; even if the water spray system is turned off, it can only be cleaned but not washed, because it lacks a filter barrel device, it cannot work
