A cleaning device and method for resource recovery of waste filter bags

Abstract

A cleaning device and method for recycling waste filter bags. The device includes a negative pressure ash chamber, a feeding platform, a roller brush, an electromagnetic vibrator, a compressed air blowpipe, an air compressor, a cutting and tearing machine, a hair cutting roller, and a high-pressure filter bag. Water pipes, electric heating coils, mesh curtains, fiber collection hoppers, dust collectors, exhaust fans, sewage tanks and clean water tanks. The method is: carry and transfer the waste filter bags through the feeding platform and mesh curtain, remove the loose and hardened dust on the surface of the filter bags with a strong brush, and then remove the dust stuck in the filter material layer by electromagnetic vibration, and then pass compressed air The dust remaining on the surface of the filter bag is blown off, and then the whole filter bag is fragmented by a cutting machine and a hair roller, and then the loose fragmented fibers are washed with high-pressure water, which can effectively remove the remaining dust, and finally through electric heating The coil heats the compressed air, and uses the hot air to air-dry the shredded fibers, and finally obtain clean raw material products that can be recycled.

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
