A green treatment equipment for recycling metallurgical waste gas

Abstract

The invention discloses a metallurgical waste gas recycling green treatment equipment, which comprises a smoke inlet pipe and a water storage tank. One end of the smoke inlet pipe is provided with a smoke outlet pipe. The inside of the smoke pipe is connected with a pair of condensing filter plates, the inner wall of the smoke outlet pipe is fixedly connected with a bracket, the upper end of the bracket is fixedly connected with a steam generating pot, and the upper end of the steam generating pot is fixedly connected with a plurality of evenly distributed air jet heads; the present invention A kind of metallurgical waste gas reuse green treatment equipment, which uses the waste heat of metallurgical waste gas to heat and boil the water in the steam generating pot, and sprays water vapor with a certain pressure from the jet head, which is liquefied into small water droplets and can be directly Combined with the dust particles in the metallurgical waste gas to achieve the effect of spraying, so that the water vapor and the dust particles in the metallurgical waste gas form a combination and fall, which can greatly eliminate the dust particles in the metallurgical waste gas without generating more waste water , no need to add additional heat source, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of metallurgical waste gas treatment equipment, in particular to green treatment equipment for metallurgical waste gas reuse. Background technique [0002] The main pollutants of metallurgical waste gas in the metallurgical process are: flue gas containing fluorine, gas containing dust, flue gas containing nitrogen oxides, etc. The emission of metallurgical waste gas is large, and the pollution area is wide; the temperature is high, the composition is complex, the dust particles are fine, and the adsorption force is strong. [0003] Since metallurgical waste gas contains not only dust but also other gases, more scientific methods are needed. There are two dust removal methods for such pollutants, dry and wet. Commonly used dry dust collection equipment includes dust chamber, cyclone dust collector, bag filter and electrostatic precipitator, etc.; wet type is suitable for dusty flue gas with high moisture co...

Problems solved by technology

[0004] The temperature of metallurgical waste gas is high, and its temperature can reach about 400 degrees Celsius. Even if the waste gas is utilized, it also has very large energy, and the temperature can be higher than 100 degrees Celsius. However, the treatment of metallurgical waste gas in the prior art is generally not Being able to recycle the energy in the exhaust gas will cause a large waste of energy. At the same time, the dust in the flue gas cannot be treated well in the prior art. Using traditional dust treatment equipment will produce large consumables cost
