System and method for purifying industrial gas in gas explosion mode

Abstract

The invention relates to the field of industrial gas purification treatment. Industrial gas is fed into turbulent flow water in a gas explosion bin by a foam maker to be converted into a plurality of bubbles with different sizes, the bubbles are impacted and extruded by the turbulent flow water, the air pressure in the bubbles is increased until the bubbles burst, namely gas explosion, and harmful substances in the gas are rushed into water along with gas explosion waves to be in strong contact with water, is instantly wrapped and stored by the water, enters a settling bin along with the spiral water flow and the gravity, and then is discharged from a blow-off pipe along with the water flow; the industrial gas purified in a gas explosion mode is converted into clean gas, the clean gas is separated from the gas explosion bin and enters a dehydration bin to be converted into mist, water molecules in the mist are gathered through a condenser and a drop catcher to be converted into water drops to be recycled, and the dehydrated gas enters a transition bin and then is exhausted through an exhaust pipe; sewage carrying harmful substances enters a liquid-sewage separation unit through a blow-off pipe to be subjected to sewage-liquid separation, the harmful substances are retained in a filter material, and the sewage is converted into clear water; and the clear water is fed into a gas explosion purification unit through a water supply pump for cyclic operation.

Description

[0001] technology neighborhood [0002] The invention relates to the vicinity of industrial gas purification and treatment, in particular to a system and method for purifying industrial gas by means of explosive gas. [0003] technical background [0004] At present, the Ministry of Ecology and Environment and other relevant ministries and commissions jointly describe the ultra-low emission of industrial gases in iron and steel and thermal power enterprises refers to the implementation of upgrades and transformations in all production links (such as sintering, pelletizing, coking, ironmaking, steelmaking, steel rolling, and power plants) and meet the requirements. Flue gas particulate matter, sulfur compounds such as SO 2 , nitrogen oxides such as NO X The hourly average value of emission concentration is not higher than 10, 35, and 50 mg / m3 respectively, and all enterprises are required to choose mature and applicable environmental protection transformation technologies such ...

Problems solved by technology

[0012] The purpose of the present invention is to solve the existing technical problems such as substandard emissions of harmful substances in industrial gases and high operating costs, and to provide a system and method for purifying industrial gases by means of explosion. The turbulent liquid turns into a number of bubbles of different sizes, and the turbulent liquid produces pressure and impact on the bubbles, until the bubbles burst, that is, "explosion". The harmful substances in the gas stay in the liquid, and the gas is purified by the liquid to discharge. Require
