Dust recycling system

Abstract

The invention belongs to the technical field of environmental protection systems, and particularly discloses a dust recycling system. The dust recycling system comprises a cooling unit, a dust removalunit and a recycling unit, wherein the dust removal unit comprises a dust removal box; a partition plate divides the dust removal box into an upper part, namely an air purification chamber and a lower part, namely a filter chamber; a plurality of fixed filter bags and movable filter bags are alternately arranged in the filter chamber; an air exhaust mechanism is arranged in the air purification chamber; the upper ends of the movable filter bags are connected with a lifting mechanism; the lifting mechanism is connected with the air exhaust mechanism; the air exhaust mechanism works to drive the movable filter bags to rise up and fall off through the lifting mechanism; upper scraper blades are arranged at the upper parts of the movable filter bags; lower scraper blades are arranged at the lower parts of the fixed filter bags; the insides of the fixed filter bags are connected with rotating shafts, driven by the lifting mechanism, in a rotatable manner; flexible blades are arranged on the rotating shafts; the recycling unit comprises a material feeding mechanism and a screening mechanism; the material feeding mechanism is communicated with an ash bucket; and the screening mechanism is communicated with the material feeding mechanism and is located at the end, far away from the ash bucket, of the material feeding mechanism. The dust recycling system realizes ash cleaning of the filter bags in a dust filtering process, and is high in dust removal efficiency and high in dust recycling 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...
