Dust removal device in wide-interval polar matching form and dust removal method

Abstract

The invention relates to a dust removal device in a wide-interval polar matching form and a dust removal method. In recent years, boilers adopting raw coal as a fuel are greatly increased along the rapid development of economy, the surrounding environment is greatly endangered by atmospheric pollutants discharged by coal-fired boilers, the main way for reducing or decreasing the pollutants discharged by the coal-fired boilers is to provide each type of smoke prevention and dust removal devices matched with the boilers, and the performance and efficiency of the dust removal device are keys fordetermining the danger degree of a boiler to the surrounding environment. The dust removal device in the wide-interval polar matching form comprises an exhausting pipe (1) connected with an air collection cap (2), wherein the air collection cap (2) is connected with a main collection pipe (3), the main collection pipe is connected with an ash bucket, and the ash bucket is connected with an air uniformizing pipe (5). The dust removal device is applied to dust removal and purification.

Description

Technical field: [0001] The invention relates to a dust removal device and a dust removal method in the form of wide-spacing pole matching, which are applicable to dust purification in various industrial fields such as hardware, cement, building materials, ceramics, electronics, chemical industry, casting, metallurgy, electric power, machining, and nonferrous metals. Background technique: [0002] In recent years, with the rapid development of the economy, the number of boilers fueled by raw coal has increased a lot. The air pollutants emitted by coal-fired boilers have caused great harm to the surrounding environment. However, the main way to reduce or reduce the pollutants emitted by coal-fired boilers is to combine with Various types of smoke and dust removal devices are matched with the boiler, and the performance and efficiency of the dust removal device is the key to determining the degree of harm a boiler will cause to the surrounding environment. The traditional dust...

AI Technical Summary

Problems solved by technology

The traditional dust removal equipment is relatively complicated, which requires a high level of equipment transportation, installation and maintenance management; there are certain requirements for the specific resistance of dust, so there is a certain choice for dust, and it is impossible to achieve high purification efficiency for all dust; it is affected by the temperature of the gas The operating conditions such as humidity and humidity have a great influence. The same kind of dust is operated under different temperature and humidity, and the effect obtained is very different.
