Abstract

The invention discloses a method and a special-purpose device for producing a chlorine dioxide disinfectant having a concentration of 4%. The method comprises the following steps that chlorine dioxide gas produced by a reactor (2) and hot gas produced by an absorption tank (1) are synchronously fed orderly to an absorption tower (3) and a washing tower (4) by a gas-guide pipe, absorption liquids which are in the absorption tower (3) and the washing tower (4) and absorbe chlorine dioxide enter into the absorption tank (1), the absorption liquid containing chlorine dioxide is mixed with an absorption liquid in the absorption tank (1), one part of the mixed solution is directly fed into the absorption tower (3) and the washing tower (4), the other part of the mixed solution is subjected to cooling device (5)-based on-line heat-exchange cooling to form a cooling absorption liquid, and the cooling absorption liquid is mixed with the absorption liquids directly fed into the absorption tower (3) and the washing tower (4) by a circulating pump (7) until the production reaction is finished so that a product is obtained. The method improves safety, prevents environmental pollution, has a low investment cost, utilizes less equipment, has a small land occupation area and can be operated simply and conveniently.

Description

technical field [0001] The invention relates to the technical field of inorganic chemical industry, in particular to a production method and special equipment for a 4% chlorine dioxide disinfectant. Background technique [0002] At present, the production capacity of the equipment for producing 2% chlorine dioxide disinfectant (that is, stable chlorine dioxide solution) in my country is relatively small. These are small preparation equipment in the industry, which can meet the needs of most users for sterilization and disinfection. Different domains play a broad role. However, due to the high water content of 2% disinfectant, the high transportation cost, and the small mass fraction, it cannot meet the needs of some users who need 4% or more disinfectant, which is limited in application. Therefore, the market still needs to produce 4% or more disinfectant products. For the disinfectant preparation process, the key to the production of high-quality fraction disinfectants is ...
