Cloth bag electrostatic combined type environment-friendly dust remover

Abstract

The invention discloses a cloth bag electrostatic combined type environment-friendly dust remover in the technical field of dust removers. The dust remover comprises an electrostatic box, a cloth bagbox and a pretreatment box, wherein the cloth bag box and the pretreatment box are both arranged on the right side of the electrostatic box; the cloth bag box is positioned on the upper side of the pretreatment box; an ash bucket is arranged on the lower side of the electrostatic box; an inclined ash bucket is arranged on the lower side of the cloth bag box. According to the dust remover, oppositeblowing pipelines are arranged so that the air flow entering the electrostatic box is divided into two oppositely-blowing air flows, after air flow opposite blowing, the gas flow rate is drasticallyreduced, the residence time in an electrostatic dust collection plate is prolonged, and electric precipitation effect is improved; the dust removal plate can be subjected to dust removal through an arranged sound wave vibration instrument, the sound wave vibration instrument can also act on the cloth bag, so that the spraying and blowing frequency is reduced; dust on the dust removal plate can befurther removed through an arranged impact dust removal mechanism, dust in the inclined ash bucket can be helped to slide down, and flue gas which is not purified thoroughly can be subjected to circulating purification through an arranged circulating pipeline.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to a cloth bag electrostatic composite environmental protection dust collector. Background technique [0002] The dust removal equipment supporting coal-fired power plant boilers in my country is mainly electrostatic precipitators. So far, the capacity of boilers using electrostatic precipitators in the power industry accounts for more than 95% of the total capacity. The dust removal efficiency of the electrostatic precipitator is affected by many factors such as the design level, the operating condition of the boiler, the type of coal fired, and the physical and chemical properties of the dust. Due to the variety of coal types in my country's coal-fired power plants, coupled with reasons such as operation and maintenance, most of the electrostatic precipitators in service are difficult to achieve the design efficiency. On the other hand, as the dust concentration increase...

Problems solved by technology

[0004] However, the work boxes of the above-mentioned device are arranged separately, the overall structure is large in volume and occupies a large area, and the device does not have a corresponding dust removal mechanism for the electrode plate. After a period of use, the electrode plate is covered with dust, which affects the dust removal efficiency. Frequent use of blowing equipment to remove dust from the cloth bag will cause damage to the cloth bag, and the airflow in the device flows through the dust removal electrode plate at a faster speed, and the electrostatic dust removal effect is poor
