Calcium carbide furnace purification dust treatment system

Abstract

The invention discloses a calcium carbide furnace purification dust treatment system. The system comprises two screw feeders, two mixers, a stirrer, a storage bin and a water mist filtering deduster;the material outlets of the screw feeders are communicated with feed inlets at the tops of the mixers; the screw feeders and the mixers are connected in a one-to-one correspondence manner; the two mixers are placed at the tops of two ends of the stirrer, and discharge outlets at the lower parts of the mixers are communicated with a material inlet at the top of the stirrer; the storage bin is arranged below the stirrer, and a material outlet at the bottom of the stirrer is communicated with the storage bin; and water mist nozzles in the mixers are communicated with the water outlets of the atomization water pump of the water mist filtering deduster through a pipeline. The system which mixes and stirs calcium carbide furnace purification ash and water has the advantages of easiness in stacking, reduction of the occupied area, no flying dusts, and no dust pollution, and the obtained stirred and mixed material can be used as a raw material for producing bricks, and also can be used as an exterior wall heat insulation material.

Description

Technical field: [0001] The patent of the invention belongs to the field of industrial environmental protection, and specifically relates to a processing system for purifying ash of a calcium carbide furnace. Background technique: [0002] When smelting calcium carbide, a large amount of by-product purification ash is usually produced, and the current treatment of the purification ash is usually to be directly stacked on the production site or transported to other places; if it is directly stacked on the production site, because the purification ash contains coke, it will It will burn, and the dust is difficult to pile up, and it occupies a large area; if it is transported to other places, because the particle size of the calcium carbide furnace purification ash is only 300 mesh, during the transportation process, it will cause dust to fly out, pollute the environment, and the calcium carbide factory will directly discharge the waste water It will also pollute the environmen...

Problems solved by technology

[0002] When smelting calcium carbide, a large amount of by-product purification ash is usually produced, and the current treatment of the purification ash is usually to be directly stacked on the production site or transported to other places; if it is directly stacked on the production site, because the purification ash contains coke, it will It will burn, and the dust is difficult to pile up, and it occupies a large area; if it is transported to other places, because the particle size of the calcium carbide furnace purification ash is only 300 mesh, during the transportation process, it will cause dust to fly out, pollute the environment, and the calcium carbide factory will directly discharge the waste water It will also pollute the environment. If it is discharged after purification, the cost of wastewater treatment will increase. Therefore, mixing the purified ash and wastewater before treatment is currently the most preferred solution

[0003] However, in the process of mixing purified ash and water, the mixing is usually uneven, some materials have been wetted, and some materials have not been wetted; in addition, due to the high viscosity of the purified ash in contact with water, it will adhere and accumulate on the side wall of the mixer. , is not easy to fall off, which leads to low mixing efficiency; during the mixing process of purified ash and water, the purified ash easily diffuses into the atmosphere and pollutes the environment. Poor, after dust removal, there is still a large amount of dust diffused into the air; in addition, the mixture of purified ash and water is usually more viscous, and it is difficult for the current mixer to mix the two evenly during the mixing process, and the mixture is easy to block. in the blender
