The method of retracting and retracting the high temperature dust collection baffle

Abstract

The invention relates to a method for folding and unfolding a high-temperature dust-collecting baffle plate. A high-temperature dust-collecting hood device is installed in a position of a smelting blast furnace where molten iron is poured to a hot-metal bottle; the high-temperature dust-collecting hood device comprises a high-temperature dust-collecting baffle plate device, a high-temperature dust-collecting baffle plate folding and unfolding device and the like; the high-temperature dust-collecting baffle plate folding and unfolding device consist of a motor, a speed reducer, a band-type brake device, a resisting device, a coiling device, a pulley, a steel rope, a high-temperature chain, a high-temperature dust-collecting baffle plate, a manual winding device, a dust-collecting hood, a dust-collecting fan and the like. According to the method provided by the invention, the dust-collecting efficiency of the dust-collecting hood is improved, suction of cold air or clean air is reduced, and the ineffective energy consumption is reduced. At the same time, the effective capture amount of dust-containing flue gas is increased and pollutions to operating post and ambient environment are reduced. The method can be widely applied to the technical field of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for receiving and placing a dust collection baffle at the outlet of high-temperature molten iron in a smelting blast furnace. Background technique [0002] Due to the working environment temperature of 800°C-1200°C in the existing high-temperature dust collection device for molten steel in smelting blast furnaces, ordinary dust collection cover materials can hardly work normally, especially the published patent: "Dust Collection Device for Unloading Dust", application number: 200520099342 .X. [0003] Existing smelting blast furnace molten iron taphole, the train carries the molten iron tank and drives into the bottom of the taphole molten iron tank. When the molten iron is poured into the molten iron tank, there will be a large amount of yellow smoke and dust overflowing. It is necessary to install a dust collection hood device to collect th...

Problems solved by technology

[0004] When the molten iron in the blast furnace is poured into the molten iron tank, a large amount of yellow smoke and dust overflows. In order to overcome the shortcomings of the existing ash unloading and dust collection device that cannot work normally, a method of retracting and retracting the high-temperature dust collection baffle is invented.
