Therefore, the dust is required to be removed in time after the resistance of the dust remover reaches a certain value, the existing dust removing device mostly adopts a mechanical vibration or blowing pulse mode, the mechanical vibration dust removal is simple to implement, but the dust removing effect is poor, and dust is remained on a filter bag after dust removal and is unevenly distributed, so that the uniform flow of air flow is not facilitated; the blowing pulse dust removal adopts compressed air to make the filter bag generate repeated expansion and impact vibration, so that the deposited dust attached to the filter bag is shaken off, the dust removal is thorough, but the primary layer is damaged; therefore, the existing dust cleaning mode can damage the dust primary layer attached to the filter bag in different degrees, thereby reducing the dust removal efficiency.
Disclosure of Invention
In order to overcome the technical defects in the prior art, the invention provides a bag type dust collector to solve the problem that the dust primary layer cannot be effectively protected during dust removal of the existing dust collector.
The technical scheme for solving the problem is as follows: the dust-containing gas filter comprises a shell, an ash bucket, a cover plate, a horizontally arranged partition plate arranged on the inner side of the shell and a plurality of vertically arranged filter bags arranged on the partition plate, wherein the partition plate divides the inner side of the shell into two parts which are not communicated with each other from top to bottom; the openings of the filter bags are upward and are arranged in the flow mixing chamber, the upper ends of the filter bags penetrate through the partition plate and are arranged on the partition plate, so that the inner sides of the filter bags are communicated with the flow collecting chamber; the baffle plate is provided with a plurality of rotatable ferrules arranged in the mixed flow chamber, the ferrules and the filter bags coaxially correspond one to one and are sleeved on the periphery of the filter bags, the lower ends of the filter bags are sleeved with rotatable rotating rings coaxially arranged with the filter bags, the ferrules and the rotating rings are connected through a plurality of scraping plates arranged on the periphery of the filter bags, and the rotating rings are provided with turbofan arranged below the filter bags.
The invention drives the turbofan to rotate by the pressure when the gas flows, so that the scraper scrapes off the dust on the surface of the filter bag, thereby not only achieving the ideal dust cleaning effect, but also effectively protecting the dust initial layer accumulated on the surface of the filter bag, and enabling the dust remover to be in the optimal dust cleaning state all the time; meanwhile, the real-time ash removal enables the pressure on two sides of the filter bag to be kept in a stable pressure difference range, so that the filter bag can be effectively protected, and the service life of the filter bag is prolonged.

Preferably, the filter bag 5 is composed of a supporting framework 51 vertically arranged and a cloth bag 52 with an upward opening sleeved outside the supporting framework 51.
Preferably, the scraper 13 is a vertically arranged straight plate structure.
Preferably, the scraper 13 has a spiral structure wound along the axis of the rotary ring 12.

When the dust-containing flue gas dust collector is used, dust-containing flue gas enters the mixing chamber 6 through the air inlet 8, the dust-containing flue gas is blocked and collided by the guide plate 10 to flow downwards and generate inertial collision with the dust hopper 2, and dust with larger particles is settled under the action of self gravity and falls into the dust hopper 2; the dust with smaller particles flows upwards along with the gas and collides with the filter bag 5, the dust with smaller particles is retained on the outer surface of the filter bag 5 due to the blocking and screening functions of the filter bag 5, and the clean gas enters the filter bag 5 and enters the collecting chamber 7 from the opening of the filter bag 5; the clean gas is continuously gathered in the collecting chamber 7 and is discharged through the air outlet 9.
Along with the continuous inflow of the dust-containing flue gas, the dust accumulated on the surface of the filter bag 5 is gradually increased, so that the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter bag 5 is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced; in addition, the air volume of the dust removal system is obviously reduced due to the overhigh resistance of the dust remover; therefore, the invention adopts a convenient ash removal device: when dust-containing flue gas flows in the dust remover, the airflow flows upwards after being blocked by the guide plate 10 and the dust hopper 2, so that the flow of the dust-containing flue gas can push the turbofan 14 to rotate, the rotary ring 12 drives the scraper 13 and the ferrule 11 to rotate, dust accumulated on the outer surface of the filter bag 5 is scraped when the scraper 13 rotates, and a dust initial layer with a certain thickness can be reserved at the same time, so that the flue gas filtering effect is kept in an optimal state; due to the rotating connection between the ferrule 11 and the partition plate 4 and the rolling supporting effect of the balls 15, the ferrule 11 and the rotating ring 12 rotate stably without radial shaking, a preset distance between the scraper 13 and the filter bag 5 can be guaranteed, an ideal ash removal effect is achieved, and the problem that the dust on the filter bag 5 is uneven in thickness due to the radial shaking of the scraper 13 and the dust removal efficiency of the dust remover is affected is avoided.
For most service environments, the rotation of the turbofan 14 can be effectively realized due to certain pressure and speed when the dust-containing flue gas enters the dust remover, and when the pressure or the speed of the dust-containing flue gas is lower under special conditions, the dust-containing flue gas can be externally connected with simple pressurization equipment such as a blower and the like to increase the pressure or accelerate the flow velocity when the dust-containing flue gas enters the air inlet 8, so that the reliable rotation of the turbofan 14 is ensured, and the scraper 13 is enabled to finish the dust cleaning operation.
