Abstract

A method for disinfection and sterilization of ice-making water, which relates to a method for disinfection and sterilization of water. The process of the method is as follows: an air source passes through an ozone generator to generate an ozone mixed gas, and the ozone mixed gas passes through an ozone gas pipe and water that enters a water inlet pipe At the same time, it enters the high-efficiency gas-liquid mixer, the gas-liquid mixed water from the high-efficiency gas-liquid mixer flows into the contact oxidation tank, the excess tail gas is absorbed and discharged from the tail gas, and the ice-making water is introduced into the ice machine to produce ice cubes. The ozone disinfection of the present invention is in a relatively sealed environment, with uniform diffusion, good inclusiveness and permeability, and the ice cubes generated after this treatment are mainly used in cold storage rooms to keep vegetables and fruits fresh. The invention is widely used in light industries such as beer and beverages, slaughtering industries, chemical industry and construction fields.

Description

A kind of ice-making water disinfection and sterilization method

technical field

The invention relates to a water disinfection and sterilization method, in particular to a disinfection and sterilization method specially used for ice making water.

Background technique

With the continuous improvement of people's living standards and the rapid development of the export processing industry, the market's requirements for the internal quality of food are increasing day by day. Due to the physical characteristics of ice, its use in the field of food processing has been continuously expanded, covering almost all industries of food processing. Therefore, the effect of disinfection treatment of ice-making water directly affects its market competitiveness. Some of the existing ice-making water directly use tap water or after some simple treatment, use ultraviolet rays, chlorine gas, hypochlorite, etc. to treat water. The disadvantage of chlorine is: there is residual pollution in the water disinfected by chlorine, which is harmful to human body and has peculiar smell.

Contents of the invention

The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a method for ozone disinfection and sterilization of ice-making water, which can effectively sterilize the ice-making water, purify the water quality, and will not produce secondary pollute.

The purpose of the present invention is achieved through the following technical solutions:

A method for disinfection and sterilization of ice-making water, the process of which is as follows: the gas source generates ozone mixed gas through an ozone generator, and the ozone mixed gas enters a high-efficiency gas-liquid mixer through an ozone gas pipe and water entering a water inlet pipe at the same time, from the high-efficiency gas The gas-liquid mixed water from the liquid mixer flows into the contact oxidation tank, the ozone online detector controls the operation of the ozone generator, the excess tail gas is discharged from the tail gas absorption port, and the ice making water is introduced into the ice machine to produce ice cubes.

A kind of ice-making water disinfection and sterilization method as mentioned above, its ozone on-line detector controls the running situation of ozone generator, when the ozone concentration value is 0.04mg/M ^When , the ozone system stops working automatically, turns on the ozone power supply otherwise.

Advantage and effect of the present invention are:

1. The ozone disinfection of the present invention is in a relatively sealed environment, with uniform diffusion, good inclusiveness and permeability, which overcomes the problem of disinfection dead ends in ultraviolet sterilization, and achieves the purpose of omnidirectional, fast and efficient disinfection and sterilization.

2. Due to the wide spectrum of sterilization of the present invention, it can kill various microorganisms such as bacterial propagules, spores, viruses, fungi and protozoan spores, and can also destroy botulinum and toxins and rickettsia, etc., and simultaneously It has a strong function of removing mildew, fishy, smelly and other peculiar smells.

3. Ozone is generated by oxygen in the air. In the process of disinfection and oxidation, the present invention does not have any residual substances, which solves the problem of secondary pollution of residues during disinfection with disinfectants.

4. The invention is equipped with a high-efficiency gas-liquid mixer made of stainless steel, which can mix gas and liquid at one time, and has the advantages of small size, light weight, and stable performance. Thereby improving the contact area between ozone and the oxidized substance in water, the reaction probability and the utilization rate of ozone.

Detailed ways

As shown in the figure, the ice-making water disinfection device of the present invention includes parts such as an ozone generator 2, a water inlet pipe 4, a high-efficiency gas-liquid mixer 5, a contact oxidation tank 7, an ice maker 9, and an online ozone detector 10. The ozone generator 2 described above is composed of a chassis, a high-voltage control power supply board, an ozone generating tube, a fan and a circulating water cooling system, a gas source flow control pipeline, and an electrical control system. When the ozone generator is powered on, the high-voltage power supply supplies the ozone generating tube to work, and the gas source 1 is adjusted and input to the ozone generating tube through the flow meter. 3 and the water entering the water inlet pipe 4 enter the high-efficiency gas-liquid mixer 5 at the same time, and the high-efficiency gas-liquid mixer is developed according to the principle of the Venturi tube. The mixer is made of stainless steel, and its biggest feature is the one-time mixing of gas and liquid (at present, the commonly used jet is to mix about 10% of the liquid with the gas, and then mix the obtained mixed liquid with the other 90% of the liquid). It avoids the inhomogeneity of gas-liquid mixing that may be caused by the traditional ejector due to the need for secondary mixing. It has the advantages of small size, light weight and stable performance. Experiments have proved that during the operation of the mixer, air and water divide each other into mist-like balls, thereby increasing the contact area and reaction probability between ozone and oxidized substances in water, thus greatly improving the utilization rate of ozone. The gas-liquid mixed water 6 from the high-efficiency gas-liquid mixer 5 flows into the contact oxidation tank 7, and the ozone sterilizing mechanism in the contact oxidation tank realizes the bactericidal effect by oxidizing and destroying the structure of the microbial film. Ozone first acts on the cell membrane, causing damage to the membrane components and causing metabolic disorders. Ozone continues to penetrate and penetrate the membrane to destroy lipoproteins and lipopolysaccharides in the membrane, change the permeability of cells, and cause cell lysis and death. The ozone inactivation virus is considered to be completed by oxidation directly destroying its ribonucleic acid RNA or deoxyribonucleic acid DNA material. Simultaneously, the ozone on-line detector 10 controls the operation of the ozone generator. When the ozone concentration is 0.04mg/M ³ , the ozone system will automatically stop working, otherwise, the ozone power will be turned on. Excess exhaust gas is discharged from the exhaust gas absorber 11 . The ice making water 8 is directly introduced into the ice maker 9 to produce ice cubes.
