Rotary efficient bag-type dust collector

Abstract

The invention discloses a rotary bag-type dust collector. The collector comprises an air venting box, a dust collecting box and a dust collecting bag, wherein the dust collecting box comprises an upper shell body with a bottom opening and a lower shell body with a top opening, an annular groove is formed along the brim of the top opening of the lower shell body, the bottom of the upper shell body is arranged inside the annular groove, and a ball is arranged inside the annular groove; the air venting box is arranged on the top of the upper shell body, and the center of the top of the air venting box is provided with an air outlet pipe; one end of the dust collecting bag is positioned inside the upper shell body, and the other end of the dust collecting bag is positioned inside the air venting box; an air inlet pipe is arranged on the side wall of the lower shell body, and the air outlet end of the air inlet pipe is provided with a shunting device the air outlet end of which is positioned exactly oppositely to the dust collecting bag; a rotating shaft is arranged inside the upper shell body and provided with a shaking rod perpendicular to the rotating rod, one end of the rotating shaft is provided with a stepping motor, and one end of the shaking rod is arranged correspondingly to the dust collecting bag; the bottom of the lower shell body is provided with a dust returning hopper. The rotary bag-type dust collector is excellent in the effects of removing dust and dioxin, long in service life and high in dust collection efficiency.

Description

technical field [0001] The invention belongs to the technical field of gas dust removal, and in particular relates to a rotary high-efficiency bag filter. Background technique [0002] In industrial production, a large amount of waste gas mixed with solid particles and air will be produced. If this waste gas is directly discharged into the atmosphere, it will pollute the environment and affect the health of people or other organisms. The existing dust collectors include cyclone dust collectors, wet dust collectors, filter dust collectors, electrostatic precipitators and bag dust collectors. Bag dust collectors are mostly used by large, medium and small factories because of their simple structure and easy use. However, in the current bag filter, when the dust-containing gas passes through the dust bag, the airflow speed is faster, which not only has a relatively large impact on the filter bag, which reduces the service life of the filter bag, but also has a relatively long co...

Problems solved by technology

However, in the current bag filter, when the dust-containing gas passes through the dust bag, the airflow speed is faster, which not only has a relatively large impact on the filter bag, which reduces the service life of the filter bag, but also has a relatively long contact time between the filter bag and the airflow. For a short time, the dust in the airflow cannot be fully removed, and the dust removal effect is poor; at the same time, most of the current bag filter cannot remove the dangerous substance dioxin, which includes 210 kinds of compounds, which are very stable and have a relatively high melting point High, extremely difficult to dissolve in water, soluble in most organic solvents, it is a colorless and odorless fat-soluble substance, so it is very easy to accumulate in the body and cause serious harm to the human body. If the waste gas containing dioxin is directly discharged into the atmosphere It is easy to cause harm to the human body

Although there is currently a pulse bag filter that increases the contact time between the airflow and the dust bag by shunting and decelerating, and can remove dioxins through activated carbon, there are still uneven distribution of airflow that leads to poor dust removal effect, and insufficient contact between activated carbon and airflow leads to dioxins. The problem of a lot of oxin residues; after working for a period of time, more dust is adsorbed on the dust bag, which may block the bag. Absorbed dust, however, reduces dust collection efficiency due to the need to stop dust work
