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 wood 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 wood drying equipment programme Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.

Ultraviolet is a kind of light wave invisible to the naked eye, which exists outside the ultraviolet end of the spectrum, so it is called ultraviolet. Ultraviolet ray is one of the electromagnetic waves radiated by the sun. It is a special form of material operation, which is a flow of particles that are not connected. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. When ultraviolet rays irradiate microorganisms, energy transfer and accumulation will occur, and the accumulation results in the inactivation of microorganisms, thus achieving the purpose of disinfection. When bacteria and viruses absorb more than 3600~65000uW/cm2, it has a strong destructive power on DNA and RNA of bacteria and viruses, and can make bacteria and viruses lose their viability and fecundity, thus eliminating bacteria and viruses, production Microwave wood drying equipment Achieve disinfection and sterilization effect. On the one hand, ultraviolet light can mutate nucleic acids, hinder their replication, transcriptional blockade and protein synthesis; On the other hand, the production of free radicals can cause photoionization, which will lead to cell death. Microwave wood drying equipment programme The sterilization principle of the microwave ultraviolet water treatment equipment is to use the irradiation intensity of the ultraviolet lamp, that is, the irradiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. When the irradiation intensity is constant, the longer the residence time of the irradiated disinfectant is, the closer it is to the sterilization lamp tube, the better the sterilization effect will be. On the contrary, the worse the sterilization effect will be. This equipment can be used in direct drinking water equipment to obtain good water purification effect.

The microwave electrodeless ultraviolet sterilization equipment can ensure the sterilization effect and water quality of the effluent. It is a durable and effective sterilization technology. There is no reactivation reaction and no rebound of bacteria, ensuring complete disinfection effect and water quality safety. Compared with other sterilization methods, UV has many obvious advantages, production Microwave wood drying equipment In particular, unlike chemical fungicides, the ultraviolet sterilizer will not bring toxic substances and residual substances into purified water, Microwave wood drying equipment programme The chemical composition, odor and pH value of the fluid will not be changed. This feature is very important in pharmaceutical industry and related industries. The chemical dosage of influent can often change the characteristics of products.

Microwave electrodeless ultraviolet sterilization equipment has high value in microwave ultraviolet water treatment equipment, production Microwave wood drying equipment It destroys and changes the structure of DNA of microorganisms through the irradiation of ultraviolet light, so that the bacteria will die immediately or cannot reproduce, so as to achieve the purpose of sterilization. The real bactericidal effect is UVC ultraviolet, Microwave wood drying equipment programme Because C-band ultraviolet light is easily absorbed by the DNA of organisms, the ultraviolet light of about 253.7 nm is preferred. It is a pure physical disinfection method, which has the advantages of simplicity, convenience, broad-spectrum, no secondary pollution, convenient management and automation. With the introduction of various new designed ultraviolet lamps, the application range of ultraviolet sterilization is also expanding.
