Nozzles are widely used in the industry, and the materials range from stainless steel, plastics to silicon carbide, polytetrafluoroethylene, PP (engineering plastics), aluminum alloys and tungsten steel. The application range is generally used in automobiles, electroplating, surface treatment, high pressure Cleaning, dust removal, cooling, desulfurization, humidification, mixing, gardening and other industries. There are many applications of dust removal nozzles, generally used in coal mine dust removal and other fields. Using dust removal nozzles can greatly improve the environment around us, reduce dust, reduce dust, and protect workers’ health. The following nozzle manufacturers will give you a detailed introduction to the application of dust removal nozzles? The application of dust removal nozzles in various industries.

The application of dust removal nozzle
Nozzle spray can be used not only for cooling, but also for dust removal. Thermal power plants, cement plants, refractory materials processing plants and coal-fired boilers will generate a large amount of soot and waste gas during production and operation. In view of their environmental pollution, bag-type dust removal, electrostatic dust removal, mechanical dust removal, etc. have appeared at home and abroad. Technologies such as air filtration and wet spray dust removal. These dust removal technologies are all based on force, but their popularization and application are limited due to their respective defects.
Among various dust removal technologies, the spray dust removal system uses nozzles. The spray dust removal technology has the characteristics of better dust removal effect, less investment and simple maintenance, and has received extensive attention. Spray dust removal requires that the spray parameters match each other, so that the spray dust removal can play the greatest role. With the development of spray dust removal technology, high-speed atomization jet dust removal has been further studied. High-speed atomizing jet dust removal is to spray high-pressure water through the nozzle at high speed, and generate negative pressure when passing through the air duct, so as to inhale the flue gas and soot, and mix with the water mist. Condensation and sedimentation, and can support combustion and remove harmful gases.
Chemical, food, pharmaceutical and other departments must use drying equipment when producing powders such as fertilizers, pesticides and medicines. One of the most common dryers is spray drying equipment. Nozzle spray drying is to use the spray method to make the material become liquid droplets and disperse in the hot air flow, which increases the contact area between the gas and the solid.
Exhaust noise will be generated when the diesel engine and gas turbine exhaust. By spraying the exhaust of the diesel engine and the gas turbine, the acoustic impedance of the exhaust gas will change, and the sound wave will be reflected to reduce the noise. At the same time, friction occurs when the two-phase medium is mixed, causing energy loss. Part of the noise can also be removed. The control of large rocket engine noise and vapor exhaust noise has begun to apply the spray muffler system, and achieved good results.
In some of the applications described above, the liquid is sprayed into the cross flow through the nozzle, so that the liquid is atomized and the cross flow acts, so as to play the role of combustion, cooling, dust removal, drying and noise reduction. Therefore, the design of atomizing nozzles and the research of atomization characteristics in transverse flow field can promote the application of spray in various fields. In spray cooling applications, the effect of atomization on the temperature distribution of the transverse flow is also investigated.
