Industrial circulation water quick sterilization technology and system

Abstract

The invention discloses an industrial circulation water quick sterilization technology and an industrial circulation water quick sterilization system. An ultraviolet sterilization device and chemical bactericides are combined; the ultraviolet sterilization device is used as a core device and can be arranged between a circulation pump and a cooling tower and also arranged between the circulation pump and a heat exchange device; the ultraviolet sterilization efficiency is extremely high, the chemical property of water is not changed, the water quality cannot be polluted, and damage to the heat exchange device is avoided, therefore, the industrial circulation water quick sterilization technology and the industrial circulation water quick sterilization system are very environment-friendly. Due to chemical sterilization, trace chemical bactericides are fed, so that the heat exchange device cannot be damaged, and the shortcoming that ultraviolet does not have the continuous sterilization capacity is overcome; the chemical bactericides and the ultraviolet are combined; therefore, the sterilization process is quick, high-efficiency, stable, reliable, safe and environment-friendly.

Description

technical field [0001] The invention relates to an industrial circulating water sterilization process and system, in particular to a fast, efficient, stable, reliable, safe and environment-friendly industrial circulating water sterilization process and system. Background technique [0002] In the field of sterilization of industrial circulating water, chemical bactericides are basically used to sterilize to prevent microorganisms from forming sticky scales and corroding heat exchangers and pipelines. Whether these chemical bactericides are oxidizing or non-oxidizing, if added If the amount is small, the impact on the circulating water quality may be basically negligible, but it cannot reach the bactericidal control index. In order to achieve the bactericidal index, the dosage must be large, which will inevitably have an adverse effect on the circulating water quality. Some fungicides, such as It is an oxidizing fungicide, which will directly increase the corrosion of pipes a...

Problems solved by technology

Another unique feature of ultraviolet sterilization is that it does not add substances to the water and does not change the chemical structure and properties of the water, which is more conducive to industrial circulating water. However, ultraviolet sterilization also has an insurmountable problem, which is outside the ultraviolet sterilization device. It does not have the function of continuous sterilization, that is, it does not have the ability to inhibit bacterial regeneration. In order to solve this problem, the present invention uses chemical bactericides as an auxiliary method. Since the circulating water is sterilized by ultraviolet rays, the bacterial content is already very small, and only a small amount is needed. The chemical bactericide can inhibit the regeneration of bacteria, which not only achieves the purpose of inhibiting the regeneration of bacteria to ensure the stability and reliability of the sterilization effect, but also has almost no impact on the quality of circulating water, and will not cause harm to heat exchange devices, etc. Safety and environmental protection
