Technology for producing high-purity chlorine dioxide

Abstract

The invention discloses a technology for producing high-purity chlorine dioxide, and relates to the technical field of chlorine dioxide production. The technology specifically comprises the followingsteps: 1, reacting for preparation: directly pouring an acidic solution into a reactor, and then adding a chlorate into the reactor; 2, separating and purifying; and 3, repeatedly purifying to obtainthe liquid high-purity chlorine dioxide. Chlorine dioxide mixed with carbon dioxide gas is purified to produce high-concentration chlorine dioxide, and the processing difficulty is graded according tothe concentration in order to realize grading setting of safety coefficients of a device in the manufacturing process, so the installation cost of the device is effectively reduced, the maintenance cost is reduced, and the product concentration can be selected and adjusted as required, thereby a user can select the product with a set concentration as required, convenience is provided for the user, the sales range is wide, and high income is provided for manufacturers.

Description

technical field [0001] The invention relates to the technical field of chlorine dioxide production, in particular to a process for producing high-purity chlorine dioxide. Background technique [0002] Chlorine dioxide is favored by people because of its strong bactericidal ability, no harm to humans and animals, and no secondary pollution to the environment. Chlorine dioxide is not only a broad-spectrum environmentally friendly bactericidal disinfectant that does not produce carcinogens, but also shows significant effects in sterilization, food preservation, and deodorization. Chlorine dioxide can also be used for bleaching, such as textile and Chlorine dioxide can be used instead of chlorine bleaching in papermaking. The main use of chlorine dioxide is in the disinfection of tap water, and in the bleaching of flour and wood pulp. Cysts and oocysts caused by protozoa such as Cryptosporidium. [0003] Chlorine dioxide is mostly used in domestic pulp bleaching and sterilizat...
