Efficient reaction tank for reaction of tail gas hydrogen chloride and water

Abstract

The invention discloses an efficient reaction tank for reaction of tail gas hydrogen chloride and water. The efficient reaction tank comprises a supporting frame, a tank body is arranged on the upper portion of the supporting frame, a jacket is arranged outside a pipe body, a water inlet and a water outlet are formed in the side face of the jacket, a supercharger is arranged on the top of the tank body, and a connecting pipe is arranged on the upper portion of the supercharger. The breather pipe is arranged at the lower part of the supercharger, the aeration disc is arranged at the bottom of the breather pipe, and a plurality of groups of aeration heads are arranged outside the breather pipe, so that hydrogen chloride gas is pressed into the breather pipe through the supercharger during use and is discharged through the aeration disc at the tail end of the breather pipe, the discharged bubbles are smaller, the generation of large bubbles is avoided, and the service life of the aerator is prolonged. And when the pressure is too high and the aeration disc cannot discharge gas in time, the ball valve arranged in the aeration head opens the exhaust hole due to the too high external pressure, so that the gas is discharged from the exhaust hole through the aeration head, and the aeration stability is ensured.

Description

technical field [0001] The invention relates to the technical field of reaction tanks, in particular to a reaction tank for high-efficiency tail gas hydrogen chloride and water reaction. Background technique [0002] Hydrogen chloride, a corrosive non-combustible gas, does not react with water but is easily soluble in water, and often exists in the form of hydrochloric acid mist in the air. Soluble in ethanol and ether, also soluble in many other organic substances; soluble in water, at 25°C and 1 atmospheric pressure, 1 volume of water can dissolve 503 volumes of hydrogen chloride gas. Dry hydrogen chloride is chemically very inert. Alkali metals and alkaline earth metals are flammable in hydrogen chloride, and sodium emits a bright yellow flame when it burns. An aqueous solution of hydrogen chloride is hydrochloric acid. Industrial hydrochloric acid is often slightly yellow, mainly due to the presence of ferric chloride. A common test for the presence of hydrochloric a...
