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 of nuts They will be discharged indiscriminately, resulting in more serious urban pollution. Microwave drying of nuts Price 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 not only makes the public find that the investment cost is low, but also the treatment efficiency is relatively high.

Ultraviolet disinfection can ensure sterilization effect and water quality. This is a long-term effective sterilization technology. There is no reactivation reaction and no rebound of flora, ensuring complete disinfection effect and water quality safety. production Microwave drying of nuts Compared with other sterilization methods, UV has many obvious advantages, especially the difference from chemical disinfectants is that UV sterilizers will not bring toxic substances and residues into pure water, and will not change its chemical composition, odor and pH value. This function is very important in the pharmaceutical industry and related industries. Microwave drying of nuts Price The chemical dosage of influent often changes the characteristics of the product. It can effectively kill all bacteria and viruses, and inactivate chlorine resistant microorganisms such as Legionella, Escherichia coli and Pseudomonas. Cryptosporidium, amoeba and bacteria.

1. If linear installation is required, please use the installation method of low water inlet and high water outlet to slow down the water flow rate and increase the effect of ultraviolet radiation. 2. When working, Microwave drying of nuts Price Do not look directly into your eyes with an ultraviolet lamp. When the equipment is open, repeated opening and closing will seriously affect the service life of the lamp. 3. If the water flow is too fast, please install current limiting and pressure limiting devices. 4. If the turbidity of raw water exceeds 5 degrees, a prefilter should be installed to ensure ultraviolet sterilization. 5. Please take out the quartz sleeve every time. production Microwave drying of nuts After using the disinfection lamp for two to three months, check the surface for dirt to determine the next time to clean the surface of the quartz sleeve.

The microwave ultraviolet water treatment equipment uses quartz sand filter material to remove the suspended solids, sediment, impurities, etc. of larger particles in the raw water and the turbidity of precipitation. In addition, it can also remove many organic substances, bacteria, x, etc. in the water with the decrease of turbidity, and create a good condition for disinfection after filtration. production Microwave drying of nuts Use the adsorption capacity of activated carbon to effectively adsorb organic matter, free residual chlorine, colloid, particles, microorganisms Microwave drying of nuts Price For some metal ions and decolorization, the exchange function of ion resin is used to remove calcium and magnesium ions in raw water to avoid the impact of scaling on subsequent equipment. However, the operation is laborious and material consuming. Now, the dosing system is used to directly add scale inhibitor.

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 drying of nuts Price 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 drying of nuts 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.
