Flue gas treatment device of ice net type high-temperature alloy smelting furnace

Abstract

The invention discloses a flue gas treatment device of an ice net type high-temperature alloy smelting furnace, and belongs to the field of waste gas treatment of high-temperature alloys. According to the flue gas treatment device of the ice net type high-temperature alloy smelting furnace, a filter screen and a water cooling channel in the prior art are combined through the arrangement of a heat removal ice ball net, so that when flue gas penetrates through the heat removal ice ball net, the effects of intercepting, adsorbing and cooling impurities in the flue gas are achieved at the same time. Compared with the effect of water cooling outside a flue gas exhaust pipeline or equipment in the prior art, the contact area between the heat removal ice ball net and the flue gas is larger, the distance between the heat removal ice ball net and the flue gas is closer, then the flue gas cooling effect is remarkably improved, and meanwhile, the effect of a heat gathering and ash catching string is matched, under the impact action of the flue gas, the plurality of water seepage floating ropes can be in a flying state and are interwoven with the plurality of adjacent water seepage floating ropes, so that a layer of impurity interception and adsorption barrier with a wet surface is formed below the heat removal ice ball net, and the cooling and impurity removal effects on the flue gas are better.

Description

technical field [0001] The invention relates to the field of waste gas treatment of superalloys, in particular to a flue gas processor of an ice net type superalloy smelting furnace. Background technique [0002] Superalloys refer to a class of metal materials based on iron, nickel, and cobalt, which can work for a long time at high temperatures above 600°C and under certain stresses; and have high high-temperature strength, good oxidation resistance and corrosion resistance. Good fatigue performance, fracture toughness and other comprehensive properties. The superalloy is a single austenite structure, which has good structure stability and service reliability at various temperatures. [0003] Based on the above performance characteristics, and the high degree of alloying of superalloys, also known as "super alloys", is an important material widely used in aviation, aerospace, petroleum, chemical industry, and ships. According to the matrix elements, superalloys are divide...

AI Technical Summary

Problems solved by technology

[0004] During the smelting and calcination process of superalloys, a large amount of high-temperature flue gas will be generated. Because the temperature of the flue gas is too high, in the prior art, it needs to be cooled before processing. After cooling, the impurities in the flue gas are processed. , however, in this process, the cooling and impurity treatment are carried out separately, resulting in a long time for the entire treatment of the exhaust gas and low efficiency
