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. production Microwave drying equipment 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 equipment programme Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.
In the daily treatment of sewage, many people think that sewage management needs high costs, so they improve on the basis of sewage ultraviolet disinfection equipment in large cities. But suburban residents or residents far away from the city center are often excluded because the pipeline design is not perfect, production Microwave drying equipment They will be discharged indiscriminately, resulting in more serious urban pollution. Microwave drying equipment programme At present, the public's attention to microwave and ultraviolet water treatment equipment for pollution, coupled with the adjustment of China's and cities' systems, supervises urban emissions and investment in microwave and ultraviolet water treatment equipment for urban pollution. The emergence of ultraviolet disinfection equipment for domestic sewage makes the public not only find that the investment cost is low, but also the treatment efficiency is relatively high.
The simple answer is yes, even more organisms. The research shows that 254nm ultraviolet light is effective for all food borne pathogens, natural microbiota, mold and yeast. Microwave drying equipment programme Because the size and shape of microorganisms will affect their absorption of ultraviolet light, the time required to kill each species is also different. How does UV sterilize? production Microwave drying equipment The working principle of ultraviolet sterilizer, also known as ultraviolet disinfection or ultraviolet germicidal radiation (UVGI), is to destroy some chemical bonds, disrupt the structure of DNA, RNA and protein, resulting in the inability of microorganisms to reproduce. When a microorganism cannot reproduce, it is considered dead because it cannot reproduce in the host body and is no longer infectious.
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, production Microwave drying equipment 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 equipment 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.
In the microwave and ultraviolet water treatment equipment, the reverse osmosis equipment needs three kinds of sealing rings to realize the sealing barrier of each part of the membrane shell. In order to reduce the resistance of the device, water or glycerin should be added to the surface of the sealing ring. production Microwave drying equipment Microwave ultraviolet water treatment equipment PP cotton softening equipment. Microwave drying equipment programme Special attention should be paid to the use of petroleum jelly or other petroleum grease lubricants as lubricants. Otherwise, the fresh water pipeline will crack, especially the expansion of the sealant ring. The expansion of the skirt does not directly affect the operation of the system, but will affect the reloading of the system after unloading, that is, the expansion skirt is difficult to enter the slot during loading.
When choosing microwave electrodeless ultraviolet sterilization equipment, there are different wave bands to choose from, production Microwave drying equipment It is recommended to select disinfector with deep ultraviolet wave band. Because the deep ultraviolet wave band has a wider sterilization range and stronger sterilization ability. Microwave drying equipment programme In addition, when using the disinfector in the deep ultraviolet wave band, we must pay attention to the radiation dose and time. If the irradiation dose is not enough or the time is too short, there is no way to achieve the expected sterilization effect.
