Dry pulse bag type dust collector and application thereof

Abstract

The invention discloses a dry pulse bag type dust collector and application thereof. The dry pulse bag type dust collector comprises a bracket, a square shell, an ash bucket, a filter and an air blowing device, wherein a synergistic effect is achieved by a lower disk of the filter and an upper Venturi-tube pulse airflow inlet, so that a pulse flushing effect is achieved, pulse airflow flow into a filter bag efficiently and more easily, solid impurities on the filter bag are removed effectively, a very good removing effect is achieved, and the filter bag of the filter does not need to be replaced, namely, the filter bag can be recycled. The dry type pulse bag has a reasonable structure, is easy to detach, is suitable for various filter bags; the novel air blowing device is designed, so that a large amount of pulse airflow is introduced effectively, dust sucked by the filter bag is shaken off, and a best cleaning effect is achieved; meanwhile, equipment has long service life, and is suitable for removing dust from high-temperature acid and alkaline coal-fired flue gas.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a dry pulse bag dust collector and its application, which can be used for dust removal of coal-fired boilers. Background technique [0002] With the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. Dust pollution is effectively controlled. In recent years, the country has paid more and more attention to environmental protection and the phenomenon of global warming has become serious. In order to advocate energy saving and carbon reduction, the environmental protection industry is booming. It has become the consensus of all to develop and purify the living environment of human beings. In order to maintain a clean production environment, places polluted by dust must be cleaned up in time. Dust collectors, especially bag-type dust collectors, are widely used in metallurgy, building...

AI Technical Summary

Problems solved by technology

Existing venturi tubes are only used for high-energy-consuming dust collectors with high-pressure pulsed airflow, which is unfavorable to the high-pressure resistance, anti-vibration and service life of the entire equipment; the problem that needs to be solved in particular is the structure of the existing venturi tube All are independent of the filter, which has a series of problems such as large space occupation, mismatched installation, and cumbersome assembly, and there is no good solution in the existing technology. On the one hand, due to the filter production field and the Venturi structure The manufacturing field is not integrated, and there is only a little intersection in special occasions. On the other hand, the Venturi structure is heavy, which is not conducive to the stability of filters, especially filter bags.

Therefore, the existing venturi tube is not suitable for filter cleaning, it is only for effectively mixing dust and water, in order to make dust gather; and the airflow incidence width is narrow, and the pulse efficiency is very low

Coal-fired flue gas has a high temperature, which forms good fluidity, but when it reaches the adsorption area, as the temperature of the flue gas drops, the dust gradually settles, which is very unfavorable for filtration
