Reaction device for preparing chlorine dioxide disinfectant

Abstract

The invention relates to a reaction device for preparing a chlorine dioxide disinfectant, which comprises a reaction kettle, a hydrochloric acid storage tank and a sodium chlorate storage tank, a mixing chamber is arranged at the top of the reaction kettle, the reaction kettle is internally provided with the reaction chamber and arranged at the lower end of the mixing chamber, an air inlet pipe is arranged at the upper end in the mixing chamber, and the right end of the air inlet pipe communicates with a first air pump; the first air pump is fixedly mounted on the right side of the reaction kettle, the lower end of the first air pump communicates with an exhaust pipe, the bottom end of the reaction chamber is provided with an air distribution pipe and communicates with the exhaust pipe, a second air pump is arranged in the reaction kettle and mounted in the mixing chamber, and an air suction pipe is arranged at the upper end of the reaction chamber and communicates with the second air pump, the upper end of the second air pump is connected to the connecting pipe, the connecting pipe is communicated with a gas distribution head which is arranged in the mixing chamber, and a water inlet pipe is arranged on the left side of the mixing chamber; chlorine dioxide gas generated by the mixing chamber is guided into the reaction chamber, then other gas in the reaction chamber is guided into the mixing chamber, and chlorine dioxide disinfectants with different purities can be generated according to the required concentration.

Description

technical field [0001] The present invention mainly relates to the technical field of chlorine dioxide preparation, specifically a kind of reaction device for the preparation of chlorine dioxide disinfectant. Background technique [0002] Chlorine dioxide is a non-toxic and harmless oxidizer and disinfectant. At present, the preparation process of chlorine dioxide disinfectant generally adopts hydrochloric acid and sodium chlorate (or sodium chlorite) to quantitatively inject in the reaction tank, and reaction tank produces chlorine dioxide and chlorine gas under the situation of heating chemical reaction. A certain concentration of sodium chlorate aqueous solution (or a certain concentration of sodium chlorite aqueous solution) and a certain concentration of hydrochloric acid are quantitatively transported into the reaction tank, and a gas-liquid mixture of chlorine dioxide and chlorine gas is generated after aeration reaction at a certain temperature. Make a certain conce...
