AI Technical Summary

Problems solved by technology

Among them, water bath heating has the defects of high power consumption and slow heating rate; although far-infrared internal heating solves the defects of slow heating rate and high power consumption, it has a great impact on the quality ratio of products, and ultimately affects product quality.
If the mixed generator is directly used instead of the doser, the above defects cannot be avoided, and it will cause equipment waste. Therefore, the design of dual-function equipment is to avoid these problems. Therefore, the choice of heating method is a key issue.

Abstract

The invention discloses a device for preparing chlorine dioxide with dual functions, which comprises a heater (1) and a reactor (5) connected through an overflow pipe (3), and an electric heater (1) is arranged outside the heater (1). The magnetic induction heater (2) is provided with a constant temperature heating belt (4) outside the reactor (5). The heater (1) is a tubular container made of stainless steel, and the reactor (5) is a PVC tubular reactor. The invention also discloses a method for preparing mixed chlorine dioxide and high-purity chlorine dioxide by using the device of the invention. Compared with the traditional doser and mixed generator, the equipment is integrated, the operation is simple, the safety is strong, and the operation Stable, in terms of sterilization and disinfection, it can meet the needs of water treatment in various places.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a device for preparing chlorine dioxide with dual functions and a method for preparing chlorine dioxide by using the device. Background technique [0002] The sterilization and disinfection of drinking water in our country has been using Cl for a long time 2 conduct. Since the late 1980s and early 1990s, chlorine dioxide, an internationally recognized safe and green disinfectant, has entered China. First, a mixed chlorine dioxide generator was developed, and a high-purity chlorine dioxide generator was developed successively. On this basis, chlorine dioxide disinfectant (agent A and B agent) products were successively developed. [0003] Since chlorine dioxide entered China, its main application areas are the sterilization and disinfection of drinking water, hospital sewage, and industrial circulating water, etc. It is intended to gradually replace the traditional Cl 2 disinfe...
