Most of the microwave ultraviolet water treatment equipment is installed in the plant, but some are installed outdoors. When winter comes, the temperature also drops to below zero. Because the volume of water will increase significantly in the process of solidification and freezing, new type Microwave drying of nuts Once the microwave and ultraviolet water treatment equipment and pipeline are iced, it will cause the water flowing part of the equipment and pipeline to break, resulting in economic losses. Then let's see how to maintain the microwave ultraviolet water treatment equipment in winter. Microwave drying of nuts programme In order to increase the effective thermal insulation measures for outdoor microwave ultraviolet water treatment equipment and pipes, straw rope wrapped with plastic film can be used for thermal insulation, or 1.2-1.5cm thick insulation cotton or insulation cotton pipe can be used for tape wrapping.

According to different lamp tubes, ultraviolet sterilization lamps have thermal cathode low-pressure mercury vapor discharge lamps and cathode low-pressure mercury vapor discharge lamps; The hot cathode low-pressure mercury vapor discharge lamps can be divided into straight type, H-type, U-type tube, etc. from the appearance; new type Microwave drying of nuts For different needs, it can be divided into low (no ozone), ozone, high ozone, etc. The portable microwave electrodeless ultraviolet sterilization equipment can be used for close mobile irradiation, and the ultraviolet lamp suspension irradiation can also be used. Small articles can be irradiated in the ultraviolet disinfection box. Different kinds of microorganisms have different sensitivity to ultraviolet rays. When using ultraviolet rays for disinfection, the radiation dose must be used to reach the radiation dose required to kill the target microorganisms. Microwave drying of nuts programme The product of the irradiation intensity and irradiation time of the ultraviolet lamp used for irradiation dose at the surface of the irradiated object. Therefore, according to the irradiation intensity of the ultraviolet light source, the required irradiation time can be calculated.

Now people pay more attention to health, and the demand for ultraviolet disinfection equipment will be more and more extensive. new type Microwave drying of nuts The UV sterilization equipment is highly integrated, with low maintenance costs, which saves the time and energy of operators without adding any other chemical reagents. UVC ultraviolet ray plays a real role in disinfection equipment, Microwave drying of nuts programme The ultraviolet radiation can destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms, so that the bacteria will die immediately or cannot reproduce, so as to achieve the purpose of sterilization.

Stainless steel wire woven filter screen is often used, 30-40 hole/cm filter screen is used for crude oil filtration, and 140-180 hole/cm filter screen is used for decolorization oil filtration. new type Microwave drying of nuts The selection of filter medium will affect the clarification of filtered oil and fat, and whether the cake unloading is smooth. The filter media used in the grease industry are mostly woven media, Microwave drying of nuts programme Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.

The sterilization principle of the microwave ultraviolet water treatment equipment is mainly to use the irradiation intensity of the ultraviolet lamp, that is, the radiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. Therefore, when the irradiation reaches a certain level, the disinfectant it is exposed to will stay longer, and the closer it is to the sterilization lamp, the better the sterilization effect will be, otherwise, the worse it will be. So, what are the sterilization principles and application characteristics of the submerged microwave ultraviolet water treatment equipment? Now, let's discuss it with you! After absorbing ultraviolet rays, microorganisms will cause some changes in the structure of nucleoprotein molecules in their own cells, resulting in protein denaturation and breakage on the DNA chain, as well as destruction of cross links in DNA molecules, hydration on cytosine and uracil, and even dimers on adenosine, Because dimerization destroys the normal pairing of purine and pyrimidine, it changes the biological activity of DNA. As a result, the metabolism of microorganisms will be hindered, and they cannot proliferate, produce cells and destroy them; Causes the synthesis of proteins and enzymes in bacteria to be blocked, new type Microwave drying of nuts As a result, the structure and function will be changed and destroyed, which will lead to the death of microorganisms and achieve the purpose of disinfection and sterilization. Experiments have proved that UV is the most bactericidal in the range of 240nm to 280nm, especially when the wavelength is 253.7 μ m, Microwave drying of nuts programme The germicidal effect of ultraviolet radiation is the best. Because a section of C frequency in the ultraviolet ray is very effective in destroying harmful bacteria or viruses. Because UV can kill bacteria, molds, viruses, unicellular algae and other organisms, UV is the preferred equipment for sterilization in the microwave UV water treatment equipment industry.

The UV sterilization equipment occupies a small area and the structure requirements are simple, so the total investment is small, new type Microwave drying of nuts The cost of operation is also low. At the level of thousand tons of microwave ultraviolet water treatment equipment, its cost is only 1/2 of chlorine disinfection. Microwave electrodeless ultraviolet sterilization equipment can be used in secondary water supply of high-rise buildings, electronics, medicine, food, chemical industry, beverage, cosmetics industry to produce pure water, swimming pool water disinfection and other water disinfection fields, Microwave drying of nuts programme Its disinfection process includes tap water → quartz sand filter → activated carbon filter → precision filter → reverse osmosis membrane → ultraviolet disinfection system → ultrafiltration device → water tank, which has the advantages of simplicity, convenience, broad-spectrum, no secondary pollution, easy management and automation.
