Abstract

The invention discloses a fluorine-containing waste gas recycling device of a chemical reaction kettle, and relates to the technical field of chemical waste gas. The device comprises a bottom plate, the top of the bottom plate is fixedly connected with a filter box, the device is provided with a first air pump, a cooling sleeve and a spiral pipe, and the air suction end of the first air pump sucksin external air; then the air outlet end of the first air pump discharges outside air into the spiral pipe, then the cold conduction liquid cools the air in the spiral pipe, the air suction end of the second air pump sucks in the air in the spiral pipe, and then the air outlet end of the second air pump discharges the air into the communicating box; gas in the communicating box enters the coolingsleeve through the gas outlet pipe to cool the interior of the ammoniation box, so that heat released during ammoniation reaction of absorption liquid and ammonia water is cooled, the reaction temperature is controlled to be 45 DEG C or below, and the reacted white carbon black is good.

Description

technical field [0001] The invention relates to the technical field of chemical waste gas, in particular to a recycling device for fluorine-containing waste gas from a chemical reaction kettle. Background technique [0002] The main pollutants caused by phosphorus chemical enterprises to the environment are fluorine, phosphorus and their compounds. Since fluorine is the most active element in chemical properties among halogens, organisms are easily harmed by it. For humans, because fluorine is mainly inhaled through the respiratory tract and has a strong stimulating effect, long-term exposure to fluorine-containing gas or dust can cause industrial fluorosis, and long-term intake of water and food with high fluoride content can cause endemic fluorosis . Most fluorosis is proliferative osteosclerosis and calcification of ligaments, manifested as fixed pain in the waist, legs, spinal joints and knee joints, which in turn leads to movement disorders. At present, my country pr...
