The nebulizer nebulizes the test solution and is an important part of the nebulization system. Its performance has an important impact on the measurement accuracy and chemical interference. Therefore, the nebulizer is required to spray stable, fine and uniform droplets and high atomization efficiency. Nebulizer is widely used, a variety of types, can be divided into: 1. air humidifier, mostly used to humidify the air humidifier is a kind of nebulizer. 2. medical nebulizer, a device for treating upper respiratory tract diseases, belongs to medical devices. 3. other types of nebulizer, such as hair styling hair spray equipment, composed of electronic cigarettes, one of the important structures for atomizing tobacco oil, and industrial nebulizer such as Niro atomizer, etc. Atomization technology is currently maturing, but there is still room for improvement. Traditional atomization devices are limited in scope and lack of rotating atomization methods. However, some atomizers, such as air humidifiers, often require cleaning to replace the internal atomization plate, which is time-consuming and laborious and also affects the service life of the atomization plate. Some atomizers are difficult to maintain a uniform atomization effect, thus affecting long-term use. Therefore, it is necessary to design a good rotary atomizer.

The key to achieve zero discharge of desulfurization wastewater is to realize the removal of chloride ions. The high hardness and poor stability of desulfurization wastewater, which contains a large amount of heavy metals and high chlorine radicals, is scaling and corrosive, and is also a technical difficulty in wastewater treatment. The process system is compared according to the application of domestic industrial wastewater and zero discharge technology for desulfurization wastewater. Based on the operating parameters of conventional 300 MW thermal power units, the economic benefits were analyzed based on the addition of zero-discharge treatment of desulfurization wastewater. There are three main treatment options: 1) evaporation treatment technology for desulfurization wastewater; 2) evaporation treatment technology for spraying flue gas; 3) evaporation membrane treatment technology for high salinity wastewater.

The atomization principle of desulfurization atomization disc is air rupture and impact, which produces atomized particles with small diameter, wide coverage and strong penetrating power. The gas and liquid are mixed and atomized in the air cap cavity. Through the degree of friction between the compressed air and the liquid, a very uniform and fine atomization effect is produced, and the atomized particle size is 80 microns or less under normal conditions.

A desulfurization rotary atomizer can be simply understood as a high-speed motor driven by an advanced variable frequency drive (VFD) specifically designed for use in spray drying processes to produce a dry and flowable solid product. The VFD is specifically designed to atomize liquid materials (solutions or slurries) into fine droplets (droplet size typically 30 to 50 microns). Desulfurization rotary atomizers are used for the purification of flue gases from hazardous waste incineration treatment, flue gas desulfurization in waste-to-energy power plants and zero waste water discharge from coal-fired power plants.

The high-speed centrifugal atomizer operates smoothly at high speeds, so the flange surface of the tower and the upper end of the atomizer should be substantially level during installation, and a rubber flange gasket must be added between the two planes to prevent vibration. The maintenance of the high speed centrifugal atomizer requires attention to.

Centrifugal atomizers are a widely used process in the drying industry and in liquid forming for producing powdered and granular solid products from emulsions, solutions, suspensions and plastic paste-like liquid materials. Spray drying is an ideal process when the particle size distribution, bulk density, residual moisture content and particle shape of the finished product must meet precise criteria.

Rotary atomizers are used in SDA flue gas cleaning for waste incineration, SDA flue gas desulfurization for coke ovens, SDA flue gas desulfurization for building material kilns, quenching and de-acidification of hazardous waste, small sintering machines (or shaft furnaces), and other SDA flue gas rotary atomizer fields In many fields of projects, the products used for desulfurization have replaced imports, thus reducing the cost of use for customers and reducing their dependence on imported equipment.

Rotational atomization technology is to atomize the material into micron-sized droplets by means of high-speed rotating equipment. The core equipment is the rotary atomizer, which is driven by a high speed motor and rotates at high speed. The high speed rotating atomizing turntable generates strong centrifugal force, and the material in the form of suspension or emulsion is sprayed through the nozzles of the special structure of the atomizing turntable, thus being atomized into micron-sized droplets. Rotary atomizer is a key electromechanical product widely used in chemical, pharmaceutical, food, environmental protection and other fields. In the field of air pollution control and environmental protection, rotary atomizers, including this Niro atomizer, are commonly used in power plant flue gas desulfurization and waste incineration power plant exhaust gas purification. A common kind of rotary atomizer on the market has high speed, stable operation, small vibration, continuous rotation, long service life, etc. It can be widely used in high-speed spray dryers to spray dry liquid materials into powdered finished products, and can also be applied to other industrial fields for atomization. However, the disadvantages are: high power loss and high maintenance cost.

Working principle of centrifugal atomizer: The centrifugal atomizer is the component of the spray drying unit that enables the atomizing medium to obtain high energy and high velocity, and is also the key component that plays an important role in atomization efficiency and stability of the atomization process. It uses an electric motor to drive a large gear through a coupling that engages with a pinion on a rotating shaft. The gear shaft after the first stage speed-up drives the second stage large gear to achieve high speed rotation. When the raw material liquid enters the feed tube of the centrifugal atomizer, it flows evenly through the raw material liquid distribution plate into the high-speed rotating spray plate, and the raw material liquid is sprayed into very small atomized droplets, which greatly increases the surface area of the material. Material liquid. The hot air in the drying chamber evaporates rapidly and can be dried into finished products in a very short time.
