Dust collection device for high temperature dust containing waste gas and use method thereof

Abstract

The invention discloses a dust collection device for high temperature dust containing waste gas and a use method thereof and relates to the technical field of waste gas treatment. A technical problemthat waste heat in the high temperature dust containing waste gas cannot be recycled is solved. The technical key point is that the dust collection device for the high temperature dust containing waste gas comprises a dust collection device body; the dust collection device body comprises a shell and a filtering component, wherein an air inlet and an air extracting opening are correspondingly formed in the two ends of the shell, and the filtering component is arranged in the shell; the air inlet of the shell is arranged in a shape of a tapered pipe; a heat exchanger is mounted in the air inletof the shell; a refrigerant inlet of the heat exchanger is communicated with an outside water source; a water storage tank communicating with a refrigerant outlet of the heat exchanger is arranged outside the shell; a U-shaped tube with one end communicating with the interior of the shell is arranged at the bottom of the shell; one end, far away from the shell, of the U-shaped tube is lower than the horizontal plane of the bottom of the shell. The dust collection device for the high temperature dust containing waste gas, disclosed by the invention, has the advantage that the waste heat in thehigh temperature dust containing waste gas can be recycled.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, more specifically, it relates to a dust removal device for high-temperature dust-laden waste gas and its application method. Background technique [0002] A dust removal device is a device used to remove or reduce the dust content in a dusty airflow. The types of filter dust removal devices can be divided into bag dust removal devices, cyclone dust removal devices, electrostatic dust removal devices, desulfurization dust removal devices, etc., which are widely used in chemical, petroleum, metallurgy, construction, mining, machinery, textile and other industries. [0003] The Chinese patent with the authorized notification number CN204767936U discloses a filter and dust removal device, which includes a housing, one end of the housing is provided with an air inlet, the other end is provided with an air outlet, and a fan is connected, and the lower part of the housing is connected with a...

AI Technical Summary

Problems solved by technology

[0004] Similar to the above-mentioned filter and dust removal device in the prior art, it includes a housing and a filter assembly formed by a combination of filter components and a connection cover. The filter component includes a plurality of filter bags. When the dusty gas passes through the filter assembly, the dust in the gas It will be filtered out by each filter bag; however, in chemical, petroleum and metallurgical industries, the waste gas produced will carry a large amount of waste heat. If the high-temperature waste gas is only filtered by dust and then discharged directly, it will cause a certain waste of resources. Therefore, it is necessary to Improve
