Description
Technical Field
The utility model relates to the field of chemical industry, in particular to a difunctional chlorine dioxide preparation device.
Background
For the sterilization and disinfection of drinking water in China, Cl has been used for a long time2The process is carried out. Chlorine dioxide, a safe and green disinfectant recognized internationally, has begun to enter China since the end of the eighties and the early nineties of the twentieth century. Firstly, a mixed chlorine dioxide generator is developed, then a high-purity chlorine dioxide generator is developed, and on the basis, chlorine dioxide disinfectant (A agent and B agent) products and the like are also developed in sequence.
After chlorine dioxide enters China, the main application fields are sterilization and disinfection of domestic drinking water, hospital sewage, industrial circulating water and the like, and the chlorine dioxide is to gradually replace the traditional Cl2And (6) sterilizing. In practical application, most of the water sterilization and disinfection are carried out by using a mixed chlorine dioxide generator, others adopt a high-purity chlorine dioxide generator and a chlorine dioxide disinfectant dispenser, and the devices are determined by customers according to different requirements and different purposes. However, with the rapid development of national economy in recent years, safety and environmental protection are further enhanced, raw materials for preparing chlorine dioxide basically belong to hazardous chemicals and hazardous chemicals for controlling toxicity, under the current situation, the purchase and evidence obtaining of the raw materials are inevitably strictly controlled and are influenced and restricted by different degrees, therefore, the application and popularization of chlorine dioxide are directly influenced, some users are forced to be incapable of preparing chlorine dioxide by using a generator and directly use a chlorine dioxide disinfectant, and in order to avoid purchasing equipment again, the forced users directly change a mixing generator into a feeder for use, so that the problem of sterilization and disinfection of water bodies is solvedAnd (5) toxicity problem. Although the problem of direct purchase of hazardous chemicals is avoided and the problem of preparation of chlorine dioxide can be solved, the expensive generator is changed into the feeder, so that the equipment cost is too high and the waste is caused; even if the feeder is purchased and replaced, the equipment cost is increased, the waste is caused, and the problem of raw material interchange cannot be solved; meanwhile, there is a problem that it is not known how to select a type for a new user. In the last 30 years, whether a mixing generator, a high-purity generator or a dosing device is a single-function device in application, the mixing generator, the high-purity generator or the dosing device is not considered to be exchanged, so that no dual-function device capable of being used as a generator or a dosing device exists. According to the requirements of the current situation development, in order to solve the problem of sterilization and disinfection of users and facilitate flexible selection of raw materials, users hope to develop equipment with more than two functions for preparing chlorine dioxide so as to meet the needs of users and the market demands.
In China, most of chlorine dioxide generators used for water treatment are mixed chlorine dioxide, and reaction liquid of the chlorine dioxide generators has the problem of corrosion to materials of the reactors, so that the chlorine dioxide generators are basically made of non-metal materials, and compared with a high-purity generator, the cost of the chlorine dioxide generators is lower; chlorine dioxide disinfectant dispensers are also generally made of non-metallic materials, so that dual-function devices generally satisfy the two functions of a mixed chlorine dioxide generator and a chlorine dioxide disinfectant dispenser. The development of a dual-function device, which is a new attempt, has not been carried out for the last 30 years, and besides the requirements of the situation, the following difficulties mainly exist:
1. the mixed chlorine dioxide generator needs to be heated in the reaction, the chlorine dioxide disinfectant adding device does not need to be heated, one device is designed to have the two functions, and the key is how to solve the heating problem and the corrosion prevention problem. At present, the heating methods of the mixed chlorine dioxide generator mainly comprise two methods, namely water bath heating and far infrared internal heating. The water bath heating has the defects of high power consumption and low heating rate; although the defects of low heating rate and high power consumption are overcome by far infrared internal heating, the influence on the quality ratio of the product is great, and the quality of the product is influenced finally. If the mixing generator is directly adopted to be changed into the adding device for use, the defects cannot be avoided, and equipment waste is caused, so that the problems are avoided when double-function equipment is designed, and the selection of a heating method is a key problem.
2. The dual-function device needs to improve the heating efficiency on the basis of ensuring the product quality, and needs to adopt an efficient heating method, namely, a metal material is needed, so that the corrosion problem of a reactor is avoided by selecting any material, and the heating method becomes another key problem.
Under the current situation, safety and environmental protection are equally important, and on the premise of ensuring national requirements, the sterilization and disinfection requirements of users are met, and the dual-function equipment has certain market requirements, which cannot be met by the existing equipment. Therefore, the development of the dual function device is a need for situation development, and is an innovation and a new attempt.
