Disinfection by chlorine dioxide purification system used in central central air conditioning

Abstract

The invention relates to a chlorine dioxide sterilization purifying system for central air conditioner. It belongs to sanitary sterilizing technique field. Its characteristic is: connecting exhaust pipe of the chlorine dioxide gasifier which includes desorption tower; exhaust pipe and air pump with air-return pipe of the central air conditioner. High-purity chlorine dioxide solution generated from complete reaction flows from top to bottom in desorption tower and completes mass-transfer process with flowing air from bottom to top. It makes chlorine dioxide gas separate completely. The sterilizing effect is good and the working state of the system is regulated automatically.

Description

technical field [0001] The invention relates to a sanitation and disinfection system, which is especially suitable for central centralized air-conditioning to disinfect and purify air, and belongs to the technical field of sanitation and disinfection. Background technique [0002] With the improvement of living standards, more and more people decorate their houses, and the decoration of public places such as shopping malls, hotels and hotels is also competing for luxury. The pollution brought by modern decoration, such as formaldehyde, is quite serious indoor pollution. After the house decoration, the pollution of volatile organic compounds in the indoor air is more serious than that of the outdoor. Formaldehyde, Benzene and Toluene. In view of the harmfulness and pervasiveness of indoor air pollution, some experts believe that human beings have entered the third pollution period marked by "indoor air pollution" after "soot pollution" and "vehicle exhaust pollution".

Problems solved by technology

Existing such devices have deficiencies in the gasification of chlorine dioxide and the installation of the device: such as Chinese patent 200320111244.4, named "chlorine dioxide disinfection device for central air-conditioning system" and 200320111238.9, named "using In the two patents of "chlorine dioxide gasifier for central air-conditioning air disinfection system", chlorine dioxide separation is not complete, and the residual liquid concentration is high; the gasification device is installed in the air conditioning ventilation duct, and the liquid distribution device cuts off the air supply duct , using the wind from the air conditioner to blow away the chlorine dioxide gas, firstly because the air supply of the air conditioner is characterized by large air volume and low pressure, so the pressure loss of the circulating air will be increased; secondly, a large amount of water vapor will be brought into the air conditioning system, corroding the equipment, It is not suitable for use in occasions with strict humidity requirements; again, considering the installation, it is very inconvenient to open the air supply pipe
