Problems solved by technology

[0008] Disadvantages: Most of the filter materials are flammable and friction-prone to accumulate static electricity. When dealing with combustion gas or high-temperature gas, incompletely burned dust, sparks, flammable and explosive gases often enter the system. There is a danger of burning and explosion accidents
[0012] Disadvantages: the efficiency of trapping fine particles is not high
[0016] Disadvantages: There are certain requirements for the specific resistance of the dust. If the specific resistance is too low, it is difficult for the dust particles to remain on the dust collecting electrode, causing them to return to the airflow. If the specific resistance is too high, the charge of the dust particles reaching the dust collecting electrode is not easy to release. The formation of a voltage gradient between them will cause local breakdown and discharge. These situations will result in a decrease in dust removal efficiency. The investment is relatively large, and the equipment is relatively complicated. It requires high levels of equipment transportation, installation and maintenance management.

Abstract

The invention discloses a pulse beating bag type dust removal device and a working method thereof. The pulse beating bag type dust removal device comprises an intake pipe, a dust removal box, a pulse beating device, an exhaust pipe, a dust exhaust opening, a support and a control system. The dust removal box is arranged on the support, the intake pipe is arranged on the upper portion of one side of the dust removal box, the exhaust pipe is arranged on the upper portion of the other side of the dust removal box, the dust exhaust opening is formed in the bottom of the dust removal box, the pulse beating device is arranged at the position, on the upper portion of one side of the intake pipe, of the dust removal box, the control system is arranged on the front portion of the dust removal box, and the support is welded and formed from a steel structure. During dust removal, the control system controls the intake pipe to be opened to convey dust containing gas to the dust removal box, the dust containing gas is exhausted through the exhaust pipe after being subjected to dust removal in the dust removal box, 20 min later, the control system controls the intake pipe and the exhaust pipe to be closed, the pulse beating device is started and the dust exhaust opening is opened, after 5 min, the control system controls the pulse beating device to be stopped and the dust exhaust opening to be closed, and the system executes dust removal again. According to the pulse beating bag type dust removal device and the working method thereof, construction cost is low, the dust removal effect is good, the dust removal speed is controllable, energy consumption is low, and the handling capacity is large.

Description

technical field [0001] The invention belongs to the field of gas dust removal and purification devices, and in particular relates to a pulse rapping bag type dust removal device and a working method thereof. Background technique [0002] In recent years, haze has occurred frequently in many cities and their surrounding areas in my country. On January 29, 2013, the Ministry of Environmental Protection notified that the central and eastern regions of my country were affected by haze weather, and the air quality in many cities was severely polluted or seriously polluted. The area is about 2 million square kilometers. At present, haze has become a major atmospheric environmental problem that plagues the production and life of residents. Haze is a weather phenomenon, which refers to a large number of extremely fine dry dust particles floating in the air evenly, making the horizontal visibility The phenomenon of air turbidity less than 10 kilometers, and the reduction of atmospheric...
