Residual-heat baking-material multi-cyclone dust remover for corundum smelting furnace

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 [0001] The invention relates to the field of dust collectors matched with corundum smelting furnaces, in particular to a multi-stage cyclone dust collector for waste heat drying materials in corundum smelting furnaces; by using the waste heat generated in the production process of smelting furnaces, the furnace materials are dried and preheated, so that The incoming charge of the corundum smelting furnace is significantly increased, and the waste gas emission of the corundum smelting furnace meets the specified standards, so as to achieve the purpose of saving electricity, energy and meeting the emission standards. Background technique [0002] Corundum smelting belongs to submerged thermal electric furnace smelting method. There are three main smelting methods: fixed furnace smelting method, dumping furnace smelting method and flow method. Due to the large investment scale of exile smelting, currently my country mainly adopts fixed furnace smelting method and...

2. Chemical dust produced during the high temperature smelting process of electric arc furnace

The discharge of a large amount of high-concentration smoke and dust will cause serious harm to the environment and ecology

The particle size of the dust removal powder is relatively fine, which is harmful to the health of the human body if inhaled, and the dust contains free SiO 2 , if long-term exposure, the incidence of silicosis will be very high, which will bring huge economic losses to the enterprise

Moreover, the alkaline dust removal powder will also pollute the land.
