Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a coal gangue combustion waste gas treatment equipment. Background Art

[0002] Coal gangue is solid waste discharged during the coal mining and coal washing process. It is a kind of black-gray rock with low carbon content and harder than coal that accompanies the coal seam during the coal formation process. It includes excavation gangue during tunnel excavation, gangue mined from the roof, floor and interlayer during mining, and washed gangue picked out during coal washing. Waste gas treatment equipment is needed during the combustion of coal gangue.

[0003] The existing coal gangue combustion waste gas treatment equipment is used to transport the waste gas to the purification box through the air intake pipe for filtering, treatment and purification, so as to achieve the standard treatment of the waste gas. In the waste gas transportation process, the waste gas has a certain flow rate and the flow direction of the waste gas cannot be changed, which leads to serious blockage of the position of the filter plate opposite to the discharge port of the air intake pipe, while the normal filtering performance can still be guaranteed at the rest of the positions of the filter plate. The uneven blockage of the filter plate not only affects the flow rate of the waste gas, but also affects the filtering effect. Therefore, there is an urgent need for a coal gangue combustion waste gas treatment equipment to solve the above problems. Utility Model Content

[0022] In order to solve the problem that the existing coal gangue combustion waste gas treatment equipment conveys the waste gas to the purification box through the air intake pipe for filtering and purification during use, so as to achieve the standard treatment of the waste gas. In the waste gas transportation process, the waste gas has a certain flow rate and the flow direction of the waste gas cannot be changed, which leads to the filter plate being blocked more seriously at the position opposite to the discharge port of the air intake pipe, while the other positions of the filter plate can still ensure normal filtering performance, and the filter plate is unevenly blocked, which not only affects the flow rate of the waste gas, but also affects the filtering effect.
