Cleaning device and method for resource recycling of waste filter bag

Abstract

The invention discloses a cleaning device and method for resource recycling of a waste filter bag. The device comprises a negative-pressure ash chamber, a feeding platform, a double-roller brush, electromagnetic vibrators, compressed air blowing pipes, an air compressor, a cutting and tearing machine, an opener, high-pressure water pipes, an electric heating coil, a net curtain, a fiber collectinghopper, a dust remover, an exhaust fan, a sewage tank and a purified water tank. The method comprises the following steps of: carrying and transferring the waste filter bag through the feeding platform and the net curtain, removing loose and hardened dust on the surface of the filter bag through the powerful brush, removing the dust clamped in a filter material layer in an electromagnetic vibration mode, and blowing off the residual dust on the surface of the filter bag through compressed air; carrying out fragmentation treatment on the whole filter bag through the cutting and tearing machineand the opener, and flushing loose fragment fibers with high-pressure water to effectively remove remaining dust; and finally, heating the compressed air through the electric heating coil, carrying out drying treatment on the fragment fibers through hot air, and obtaining a clean raw material product capable of being recycled as a resource.

Description

technical field [0001] The invention belongs to the technical field of waste filter bag cleaning and recovery, and in particular relates to a cleaning device and method for waste filter bag recycling. Background technique [0002] The bag filter is the most effective equipment for controlling industrial dust and smoke emissions. The application of the bag filter can control the emission of particulate matter at an ultra-low level of 5-10 mg per cubic meter. It is used in the field of smoke control in coal-fired power plants. About 35%, it accounts for more than 95% in the field of iron and steel smelting and cement kiln smoke control, and it accounts for 100% in the field of waste incineration smoke control. [0003] For the bag filter, the filter bag is its core component, and the filter bag directly determines the effect of smoke control. As a consumable material, the filter bag has a design life ranging from 1 to 4 years and depends on the material of the filter bag and ...

Problems solved by technology

[0006] For example, the Chinese patent application with the patent application number 201910986055.7 discloses a cleaning and recycling equipment and method for waste filter bags; the Chinese patent application with the patent application number 201610115214.2 discloses a waste polytetrafluoroethylene and polyphenylene sulfide Cleaning and recovery method of blended filter bags; for the above two patent applications, although both of them involve the cleaning and recycling of waste filter bags, the cleaning process simply uses water spraying, because after long-term use of waste filter bags, the surface of the filter bags will be damaged. A large amount of hardened dust is attached, and the filter material layer will also be filled with dust. It is difficult to remove the hardened dust through a short-term water spray, especially the dust trapped in the filter material layer. Therefore, in the application effect not ideal
