Abstract
The invention relates to a residual-heat baking-material multi-cyclone dust remover for a corundum smelting furnace. The residual-heat baking-material multi-cyclone dust remover for the corundum smelting furnace comprises a furnace flue, a ventilated material bin, a ventilated material-bin feeding opening, a conveyor, a first-stage smoke-guiding pipe, a cyclone dust remover, a second-stage smoke-guiding pipe and a dust remover. When the residual-heat baking-material multi-cyclone dust remover for the corundum smelting furnace is in a working state, high-temperature waste gas is formed by waste gas and residual heat which are produced during the production of the corundum smelting furnace, and the preheating processing is carried out on a furnace material stored in the ventilated material bin when the high-temperature waste gas passes the furnace flue, so that the temperature of the furnace material is increased to 300 to 400 DEG C from a normal temperature; coarse particles and partial dust in the waste gas can be disposed by the cyclone dust remover; then, the waste gas is sucked into the dust remover through the second-stage smoke-guiding pipe and is purified and filtered into up-to-standard exhaust gas through a cloth bag, and the up-to-standard exhaust gas enters the atmosphere through a fan and a waste-gas discharging pipe. The wall plates of a filtering box are manufactured by welding PVC (Polyvinyl Chloride) foam plastic plates. Therefore, the residual-heat baking-material multi-cyclone dust remover for the corundum smelting furnace has the positive effects of no corrosion, sunburn resistance, rain-wetting resistance, easiness in constriction and low manufacturing cost.
Description
Technical field
The present invention relates to the deduster field of mating with corundum smelting stove, be specifically related to a kind of corundum smelting stove waste heat and dry material multicyclone dust collector; By utilizing the waste heat produced in smelting furnace production process, carry out drying and forewarm to entering furnace charge, the furnace charge that enters of corundum smelting stove is significantly improved, and the toxic emission of corundum smelting stove is conformed with the regulations standard, realize the object of economize on electricity, energy-conservation, qualified discharge.
