A dust recovery system

Abstract

The invention belongs to the technical field of environmental protection systems, and specifically discloses a dust recovery system, which includes a cooling unit, a dust removal unit and a recovery unit. The dust removal unit includes a dust removal box, and a partition divides the upper and lower parts of the dust removal box into a clean air room and a filter room. A number of fixed filter bags and moving filter bags are arranged alternately in the filter chamber. An exhaust mechanism is set in the clean air chamber. A lifting mechanism is connected to the upper end of the moving filter bag. The lifting mechanism is connected to the exhaust mechanism. The movement of the exhaust mechanism can be driven by the lifting mechanism. The filter bag is raised and lowered, the upper part of the moving filter bag is equipped with an upper scraper, and the lower part of the fixed filter bag is equipped with a lower scraper. The fixed filter bag is rotatably connected with a rotating shaft driven by a lifting mechanism. There is a flexible leaf on the rotating shaft. The recovery unit includes a feeding mechanism. And the screening mechanism, the feeding mechanism is connected with the ash hopper, the screening mechanism is connected with the feeding mechanism and is located at the end of the feeding mechanism away from the ash hopper. This solution realizes the dust removal of the filter bag in the process of dust filtration, and has high dust removal efficiency and dust recovery efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental protection systems, and in particular relates to a dust recovery system. Background technique [0002] In my country's metallurgy, building materials, chemical industry, and electric power industries, there are a large number of industrial furnaces and kilns, which generate a large amount of dust-containing flue gas during production and operation. According to the provisions of the National Environmental Protection Law, the flue gas must be dedusted and purified to achieve standard discharge. The dust must be Recycle. The dust removal and purification of flue gas is carried out by bag filter. When there is a lot of dust on the filter bag during the dust removal process, the filter resistance of the dust will be large, and it is difficult to operate normally. The filter bag must be cleaned of dust. The existing bag Type dust collectors usually use the recoil of compressed gas to clean the fi...
