Have you ever thought about whether you need a sterilizer on your water tank? If so, which Z is better? An aquarium scientist's differences between ozone and ultraviolet sterilizers. Ozone is a gas composed of three oxygen atoms, while the oxygen we breathe is composed of two oxygen atoms. This chemical structure makes ozone highly active, production Microwave extraction equipment That's why it's such a powerful sterilizer. Microwave extraction equipment manufactor It is meaningful that the bulb in the UV germicidal lamp is made of quartz, because quartz will not filter out the UV rays. However, water filters light according to its depth. Therefore, the water flow space between the quartz bulb and the external glass or plastic tube is usually only a few millimeters - a thicker space will reduce the intensity of ultraviolet rays and allow bacteria and other microorganisms to survive.

The technology of microwave ultraviolet water treatment equipment is to use double layer ultrafiltration membrane for microwave ultraviolet water treatment equipment, or combine ultrafiltration membrane and reverse osmosis filtration membrane for application. Microwave extraction equipment manufactor When the manufacturer of microwave ultraviolet water treatment equipment applies external pressure on the concentrated solution side, the penetration speed will decrease. When the pressure increases to a certain value, the penetration process will stop and the so-called penetration balance will be reached. The external pressure under the balance condition is called the penetration pressure. When the pressure on the concentrated solution side continues to increase, that is, when the applied pressure is greater than the penetration pressure, The solvent of purified water equipment will reverse its original soaking direction and enter the dilute solution side from the concentrated solution side through the semi permeable membrane, production Microwave extraction equipment This phenomenon is called reverse osmosis. For a long time, it will not only affect the effluent quality of the equipment, but also lead to the fouling of the reverse osmosis membrane of the main components of the equipment, resulting in the small output of the pure water equipment, the substandard effluent quality, or the equipment can not be used. In order to ensure the continuous and safe operation of pure water equipment, the maintenance of pure water equipment is very important.

VOCS catalytic combustion waste gas treatment equipment in paint shop: Catalytic combustion equipment is a kind of deodorization and deodorization waste gas treatment equipment. The concept of catalytic combustion is to use the catalytic incineration reaction of combustibles under the effect of catalyst and certain temperature conditions. Combustibles are burned under the effect of catalyst. Compared with direct incineration, catalytic incineration has a lower temperature and is quite safe. Catalytic principle and equipment composition (1) Catalyst is defined as a substance that can improve the rate of chemical reaction, control the direction of reaction, and keep its chemical properties unchanged before and after reaction. (2) The mechanism of catalytic effect The mechanism of catalytic effect is a very complicated problem, which is only briefly introduced here. In a chemical reaction process, the participation of the catalyst cannot change the original chemical balance, but only the speed of the chemical reaction. Before and after the reaction, the nature of the catalyst itself does not change. So, how does the catalyst speed up the response? The catalyst has not changed before and after the reaction, so has the catalyst participated in the reaction? In practice, the catalyst itself has participated in the reaction. It is because of its participation that the reaction has changed the original path, reduced the activation energy, and then accelerated the reaction speed. For example, the reaction A+B → C is transited through the central active complex (AB), that is, the reaction speed of A+B → [AB] → C is slow. After participating in catalyst K, the reaction is completed in an easy way: A+B+2K → [AK]+[BK] → [CK]+K → C+2K center no longer needs the transition from [AB] to C, and then the reaction speed is accelerated without changing the catalyst properties. (3) Process composition of catalytic incineration equipment: different emission occasions and different exhaust gases have different process flows. However, no matter which process flow is adopted, it is composed of the following process units. ① Waste gas pretreatment In order to avoid blocking of the catalyst bed and catalyst poisoning, it is necessary to pretreat the waste gas before entering the bed to remove the dust, droplets and catalyst poisons in the waste gas. ② Preheating equipment Preheating equipment includes waste gas preheating equipment and catalyst incinerator preheating equipment. Because all catalysts have a catalytic activity temperature, it is called catalyst ignition temperature for catalytic incineration. It is necessary to make the temperature of exhaust gas and bed reach the ignition temperature before catalytic incineration. Therefore, it is necessary to set up preheating equipment. However, for occasions where the exhaust gas temperature is high, such as enameled wire, insulating material, baking varnish, etc., and the temperature can reach more than 300 ℃, preheating equipment is not required. The hot gas heated by the preheating equipment can be arranged in the heat exchanger and bed. The heat source of the preheater can be flue gas or electric heating, and now electric heating is more used. When catalytic reaction starts, exhaust gas can be preheated with recovered reaction heat as far as possible. In the case of high reaction heat, waste heat recovery equipment should also be set to save power. The heat source temperature of preheated exhaust gas generally exceeds the catalyst activity temperature. In order to maintain the catalyst, the heating equipment should be kept a certain distance from the catalytic incineration equipment, so that the exhaust gas temperature can be evenly distributed. Starting from the need for preheating, catalytic incineration is applicable to the purification of continuous exhaust. If intermittent exhaust, not only each preheating needs energy, but also the reaction heat can not be recycled, which will result in great power waste. This should be noted in planning and selection. ③ Fixed bed catalytic reverberator is generally selected as catalytic incineration equipment. The planning of the reverberator shall be carried out according to the standard, which shall be convenient for operation, repair and catalyst loading and unloading. In the process planning of catalytic incineration, it is necessary to plan the built-up process of components according to the specific situation in the case of large air volume, that is, the preheater and the reverberator are installed separately, and the pipes are connected between them. For occasions with small air volume, catalytic incinerators can be selected to combine preheating and reaction, but pay attention to the distance between preheating section and reaction section. In the catalytic incineration of organic waste gas, the organic waste gas to be treated is easy to explode when mixed with air at high temperature, so the safety problem is very important. Therefore, on the one hand, it is necessary to control the mixing ratio of organic matter and air to keep it at the lower explosive limit; On the other hand, the catalytic incineration system should be equipped with monitoring and alarm equipment and explosion-proof measures.

When choosing microwave electrodeless ultraviolet sterilization equipment, there are different wave bands to choose from, production Microwave extraction 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 extraction equipment manufactor 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.

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 extraction 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 extraction equipment manufactor 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.
