Abstract

The invention discloses a high-temperature fluorine-containing exhaust gas treatment device. The device comprises an adsorption chamber arranged at the upper side, and a cooling chamber positioned atthe lower side, wherein the adsorption chamber and the cooling chamber are separated from each other by means of a spacer plate; an adsorption solution inlet is formed in the upper side wall of the adsorption chamber, the adsorption chamber is internally provided with turbulent balls, the top of the adsorption chamber is provided with a gas outlet, and an adsorption solution outlet is formed in the lower side wall of the adsorption chamber; a gas inlet is formed in the lower side wall of the cooling chamber; perforated sieve plates are arranged in the cooling chamber in a staggered way; a circulating water inlet is formed in the upper side wall of the cooling chamber, and a circulating water outlet is also formed in the lower side wall of the cooling chamber; the spacer plate is provided with a gas floating valve. The high-temperature fluorine-containing exhaust gas treatment device provided by the invention is good in cooling effect at the earlier period and full in absorption at thelater period.

Description

technical field [0001] The invention belongs to the field of environmental protection treatment, and in particular relates to a waste gas treatment device, in particular to a high-temperature fluorine-containing waste gas treatment device. Background technique [0002] Fluorine-containing waste gas treatment technology is to remove fluorine-containing waste gas through absorption, adsorption and other methods. Fluorine-containing waste gas refers to the gas containing hydrogen fluoride and silicon tetrafluoride, which mainly comes from industrial production processes; electrolytic aluminum and steelmaking processes in the metallurgical industry; phosphate fertilizer and fluoroplastic production in the chemical industry; iron furnaces in the foundry industry, etc. A large amount of fluorine-containing waste gas. [0003] The main methods for purifying fluorine-containing waste gas are wet absorption and dry adsorption. Dry purification treatment is to use alumina to directl...
