1、 Equipment name: purified water distribution system (pasteurization)

2、 Specification and model: hdnfp-2000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

The disinfection mode of purified water distribution system is ozone disinfection, so it needs to be equipped with double plate heat exchanger (cooling effect in summer) or ozone generator, UV lamp and other equipment. The size of pure water storage tank should conform to the peak flow of pure water, and it has a certain balance relationship with the water production capacity of pure water machine. The flow of circulating pump should be greater than the sum of peak flow and return flow. Online relevant instruments detect the water quality, once the water quality is lower than the customer's requirements, an alarm can be given.

◇ petrochemical industry: circulating water, advanced sewage treatment, chemical product manufacturing, etc.

◇ Pharmaceutical industry: infusion, injection, tablet, biochemical products, pharmaceutical manufacturing, etc.

◇ Electronic industry: metallurgy, copper industry, integrated circuit, silicon wafer, display tube and other electronic components washing.

◇ Boiler industry: deaeration water, demineralized water, boiler water softening, etc.

◇ Food industry: drinking pure water, beverage, beer, liquor and other water, sea water, brackish water desalination, etc.

6、 Distribution system:

The main purpose of purified water distribution system is to deliver purified water to each water point through distribution pump and purified water distribution pipeline. In order to ensure the flow rate and pressure of purified water in the pipeline, the designer of purified water equipment shall calculate the pressure loss caused by the pipeline system and equipment in the pipeline of purified water distribution system, so as to select the appropriate distribution pump. The pure water distribution system should also include additional equipment to further purify and disinfect the purified water while maintaining the quality of the purified water, and monitor the water quality in the pipeline. Therefore, it is necessary to use pipeline ultraviolet device to reduce the level of microorganism and total organic carbon in purified water.
7、 Pasteurization:

Pasteurization is to heat the mixed raw materials to 68~70 ℃, and keep the temperature for 30min, then rapidly cool to 4-5 ℃. Because the lethal point of common bacteria is below 68 ℃ and 30 minutes, the mixture of raw materials can kill pathogenic bacteria and most of non pathogenic bacteria after being treated with this method; the mixture of raw materials will cool suddenly after being heated, and the sharp changes of heat and cold can also promote the death of bacteria.

8、 UV sterilization:

UV is a kind of invisible light wave, which exists outside the UV end of the spectrum, so it is called UV. According to different wavelength range, it is divided into three bands: A, B and C. among them, the wavelength of band C is 240-260nm, which is the most effective sterilization band, and the strongest point of the wavelength is 253.7nm. Modern ultraviolet disinfection technology is based on modern epidemic prevention, optics, biology and physical chemistry, using specially designed high-efficiency, high-intensity and long-life C-band ultraviolet light generating device to irradiate water (air or solid surface) with strong ultraviolet C light. When water (air or solid surface) contains various bacteria, viruses, parasites, algae and others After the pathogen is irradiated by UV-C light, the DNA structure in the cells is destroyed, so that the bacteria, viruses and other pathogenic bodies in the water can be killed without using any chemical drugs, so as to achieve the purpose of disinfection and purification.
