Dust collector with dust cleaning function

Abstract

The invention discloses a dust collector with a dust cleaning function. The dust collector comprises a dust concentrator, gas filtering chambers, a flue gas input tube, a dust collector tank and a dust discharge tube. The dust collector is characterized in that the dust concentrator is welded with the bottom of the dust collector tank; the flue gas input tube is arranged in the middle of the dustcollector tank; a primary filtering net is arranged at the bottom of the dust collector tank; an efficient filtering net is arranged at the upper part of the dust collector tank; a plurality of partition plates are arranged inside the dust collector tank between the efficient filtering net and the primary filtering net; the dust collector tank is internally divided into a plurality of gas filtering chambers by the partition plates; a dust collection plate is mounted inside each gas filtering chamber; a dust collection cloth bag is connected with the upper surface of each dust collection plate;a gas outlet is formed in one side of the top of the dust collector tank; a high-pressure gas inlet is formed in a side opposite to the gas outlet; the high-pressure gas inlet is connected with a high-pressure ejection tube; the high-pressure ejection tube is connected with a high-pressure gas storage tank; the high-pressure gas storage tank is arranged at the top of the dust collector tank; a pulse electromagnetic valve is arranged on the high-pressure ejection tube.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a dust collector with ash cleaning function. Background technique [0002] In the field of industrial dust removal, the flue gas is directly discharged, and the dust in the flue gas will cause harm to the environment. Industrial dust collectors are usually used. Among them, the bag filter is a typical model of industrial dust collectors; the basic principle is that in a A certain number of cloth bags are set in the air filter chamber. After the dusty gas enters the air filter chamber from the air inlet, it can only drill into the cloth bag and then flow out of the air filter chamber from the opening end of the cloth bag, and the air is discharged through the air outlet. The dust cannot pass through. The surface of the bag, so the filtered gas dust is filtered out. In the current bag filter, in order to increase the amount of filtered air per unit time, the commonly used method is ...

AI Technical Summary

Problems solved by technology

In the current bag filter, in order to increase the amount of filtered air per unit time, the commonly used method is to increase the number of bags or increase the length of the bag, which will lead to a significant increase in the volume of the bag filter and occupy a larger use area , but in fact, in order to obtain a superior filtering effect, the air filter pores on the surface of the bag are very small. Usually, the total area of ​​the air filter pores on the surface of the bag is smaller than the cross-sectional area of ​​the bag, resulting in slow filtration efficiency and poor air filtration. The pores are easy to block, which affects the use effect of the bag, and it is inconvenient to replace and adjust, which increases the maintenance cost. It is difficult to guarantee the filtration efficiency and effect with a single filtration method, the dust removal quality is low, it is difficult to meet the use requirements, and the environmental protection performance is poor.
