Abstract

The invention discloses a chlorine dioxide preparation device and method. The chlorine dioxide preparation device which comprises a feeding tubular reactor, a discharging tubular reactor, an additionreactor and an injector are utilized; multi-stage tubular reactors are serially connected; by control on reaction time of reaction materials in the reactors, the yield of chlorine dioxide is greatly improved; and meanwhile, a reducing agent is separately added in the various stages of tubular reactors so as to disperse the chlorine dioxide to various stages, the circumstance that a large number ofchlorine dioxide is generated on one of stages of reactors is avoided, and security incidents caused by over-high yield and concentration of the chlorine dioxide are prevented. Furthermore, because the concentration and yield of the chlorine dioxide in each of the stages of reactors are reduced, the probability of decomposition of the chlorine dioxide into chlorine is reduced, and the purity of the chlorine dioxide is improved. Thus, by the technical scheme in an embodiment of the invention, the technical effects of effectively increasing safety factors of production of the chlorine dioxide,increasing the purity of the chlorine dioxide and reducing preparation costs of the chlorine dioxide are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to a chlorine dioxide preparation device and a preparation method. Background technique [0002] Chlorine dioxide is a high-efficiency, broad-spectrum, safe disinfectant and high-efficiency oxidant, widely used in water treatment purification and disinfection, sterilization and bathing, pulp bleaching, food preservation, deodorization and deodorization, aquaculture and other fields. [0003] At present, the yield of chlorine dioxide produced by the existing chlorine dioxide production process is about 75%, and in the process of producing chlorine dioxide, due to the need to apply a large amount of corrosive raw materials, it is easy to cause corrosion to the production equipment, so the production The service life of the equipment is also short, usually about 3 years; and the purity of the chlorine dioxide produced in the prior art is about 90%, and the purity is relat...
