Smelting furnace and method used for recycling of by-produced industrial salt

Abstract

The invention provides a smelting furnace used for recycling of by-produced industrial salt. The smelting furnace comprises a base and is characterized in that a smelting chamber composed of refractory bricks is arranged above the base; a heating chamber is located above the smelting chamber; a feed inlet is formed above the smelting chamber; a top cover is provided with a plurality of natural gas nozzle interfaces; the periphery of the heating chamber is provided with a flue gas outlet; and the periphery of the smelting chamber is provided with a discharge outlet. The method for recycling by-produced industrial salt comprises the following steps: a) addition of by-produced industrial salt; b) heating of the by-produced industrial salt by using natural gas to a molten state; c) high temperature oxidation of organic matters; d) discharging of gas; and e) flowing out of industrial salt. The smelting furnace and method can covert the by-produced industrial salt which cannot be directly used before into refined industrial salt, realize recycling of the by-produced industrial salt and have substantial beneficial effect and high application value.

Description

technical field [0001] The present invention relates to a melting furnace and method for recycling industrial salt by-products, more specifically, to a melting chamber formed by refractory bricks and directly heated by natural gas for recycling industrial salt by-products Furnace and method thereof. Background technique [0002] The by-product industrial salt contains a small amount of organic matter, which is difficult to be effectively treated and utilized, and cannot be directly used as a raw material for downstream products. Most manufacturers can only stockpile it or send it to a solid waste treatment center for processing. At present, the treatment cost of the solid waste treatment center is as high as 3,000-4,000 yuan / t, which is unbearable for enterprises, and the landfill is mainly treated with anti-corrosion and anti-seepage treatment before landfilling. This treatment method not only occupies land, but is also a great waste of resources, and there is a potential...

Problems solved by technology

However, when the existing rotary kiln, vertical incinerator, horizontal incinerator, box furnace, fluidized bed incinerator, or fluidized bed incinerator is used to carbonize the inorganic salt, due to the inorganic salt in the molten state and the high-temperature furnace If there is direct contact with the wall, there will be a phenomenon of "sticking to the wall", which will not only affect the normal carbonization of inorganic salts, but also shorten the service life of the equipment
