Ash removal device of dust remover used for flue gas from submerged arc furnace, and ash removal method for dust remover

Abstract

The invention discloses an ash removal device of a dust remover used for flue gas from a submerged arc furnace, and an ash removal method for the dust remover. According to the ash removal device, theoutput end of a water cooling flue is connected with a settling bin through a pipeline; the settling bin is connected with a dust remover body through a pipeline and an explosion-proof centrifugal fan; a partition plate, single bag filter members, a flow guide frame and an ash removal assembly are installed on the inner side of the dust remover body; and the flow guide frame is located below thesingle bag filter members and the ash removal assembly. According to the invention, dust removal cloth bags are used for removing dust; the flow guide frame is installed so as to reasonably divide rapidly-entering flue gas, and the overall ash removal and dust clearing effect is improved; the ash removal assembly is movably connected with the single bag filter members; when a servo motor works, abevel gear is driven to rotate, then a rotary disc rotates along with the bevel gear, then a sliding rod drives a sliding column to reciprocate up and down, and a transverse frame reciprocates up anddown at the same time; and when the transverse frame moves, the preset bristles of the transverse frame can make contact with the outer wall of the single bag filter members, and the bristles can brush away dust accumulated on the outer walls of the single bag filter members, so ash removal effect is good.

Description

technical field [0001] The invention relates to a flue gas dust collector, in particular to a dust removal device and method for a dust collector for flue gas of a mine fume furnace. Background technique [0002] Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The working feature of the submerged arc furnace is to use carbon or magnesia refractory materials as the furnace lining and use self-cultivating electrodes. The electrode is inserted into the furnace material for submerged arc operation, using the energy and current of the arc to pass through the furnace material, a...

Problems solved by technology

[0003] Electric pulse cleaning is the existing mainstream cleaning method. The use of electric pulse cleaning can carry out bag dust removal of bag filter very well. It is widely used in foreign countries, but there are still some defects, not only the price is expensive, but also the circuit system of its load makes the equipment prone to failure, so some cleaning devices use electric pulse cleaning, but its cleaning effect is average and the practicability is not good.
