Main working principles of wet electrostatic precipitator: customized Electrostatic wet precipitator Spray the water mist to the discharge electrode and corona area, the water mist will split and further atomize after being charged in the powerful corona field formed by the barbed electrode, and the collision interception, adsorption and coagulation of electric field force and charged water mist will jointly trap the dust particles, and finally the dust particles will reach the dust collector under the drive of electric field force and be trapped. The water forms a continuous water film on the dust collecting electrode, and the captured dust is washed into the ash hopper and discharged with water. Operating principle of wet electrostatic precipitator. The dedusting process of electrostatic precipitator can be divided into four stages: gas ionization; The dust is charged with ions; Charged dust moves towards the electrode; Remove the dust on the electrode. Only the objects removed by wet electrostatic precipitation are dust and droplets, but their working principles are different due to the differences in physical characteristics between droplets and dust. In principle, Qiannan Electrostatic wet precipitator First of all, the existence of water droplets has an impact on the electrode discharge. To form emitting ions, free electrons in the metal electrode must obtain enough energy to overcome the ionization energy and cross the surface barrier to become emitting electrons. It is an effective measure to reduce the surface barrier by bringing water on the electrode surface. After the metal surface is covered with water, the original "metal air" interface is divided into "metal water" interface and "water air" interface. The potential barrier of the latter two interfaces is much lower than that of the former interface. In this way, after the metal surface is filled with water, the original high barrier will be divided into two low barriers, which will greatly weaken the blocking effect of the surface barrier on free electrons and make electrons easy to launch. In addition, Electrostatic wet precipitator Price Under the action of electric field, various impurity ions in water can easily cross the surface barrier and become emission ions. All of these have changed the electrode discharge effect, enabling corona discharge under low voltage. Secondly, due to the existence of water droplets, the resistance of water is relatively small. When water droplets combine with dust, the specific resistance of dust with high specific electricity decreases, so the working state of wet electrostatic precipitator will be more stable; In addition, since the wet electrostatic precipitator is washed by water flow and has no rapping device, it will not produce secondary dust.

Qiannan Electrostatic wet precipitator Price The development trend and direction of wind turbine in the future are analyzed as follows: wind turbine is mainly used for ventilation and air exchange in various fields of national economy and various places, such as metallurgy, petrochemical, electric power, urban rail transit, textile, shipbuilding, etc. In addition to the traditional application fields, there will still be great development prospects in more than 20 potential market fields, such as comprehensive utilization of coal gangue, new dry process clinker technology, energy saving in metallurgical industry and comprehensive utilization of resources. customized Electrostatic wet precipitator With the increasing competition in the wind turbine manufacturing industry, mergers and acquisitions and capital operations among large wind turbine manufacturing enterprises are becoming increasingly frequent. Domestic outstanding wind turbine manufacturing enterprises are increasingly paying attention to the research of the industry market, especially the in-depth research of the industry development environment and product buyers. Because of this, a large number of domestic excellent fan brands have risen rapidly and become the leaders in the fan manufacturing industry!

When the bearing temperature of the fan is normal, it is ≤ 70 ℃. If it rises to 70 ℃, an alarm should (will) be given if there is an electric control. At this time, the reason should be found out. First, check whether the cooling water is normal? Is the bearing oil level normal? If the cause cannot be found for a while, the bearing temperature rises rapidly to 90 ℃, and if there is an electric control, the alarm and shutdown signal shall be sent again. Qiannan Electrostatic wet precipitator In the process of fan startup, shutdown or operation, if any abnormal phenomenon is found, it shall be checked immediately. If any small fault is found during the check, it shall be timely found out the cause and eliminated. In case of major fault (such as severe vibration, impact of fan, sharp rise of bearing temperature, etc.), stop the machine immediately for inspection. customized Electrostatic wet precipitator The lubricating oil (or grease) shall be renewed and replaced one month after the first operation of the fan. In addition to replacement after each overhaul, the lubricating oil (or grease) can be replaced once every 1~2 months under normal conditions, or according to the actual situation. Fans include fans, turbine blowers, roots blowers and turbine compressors, which are divided into seven categories in detail, including centrifugal compressors, axial compressors, centrifugal blowers, roots blowers, centrifugal fans, axial fans and Ye's blowers

Among all kinds of mechanical and electrical equipment in all walks of life in China, the motors matched with fans account for about 60% of the installed capacity of national motors, and the power consumption accounts for about one-third of the total power generation in China. In particular, Electrostatic wet precipitator Price Most fans have the phenomenon of pulling a cart from a horse during use. In addition, due to changes in production and technology, it is necessary to frequently adjust the gas flow, pressure, temperature, etc; Many units still adopt the backward way of adjusting the opening degree of the wind shield or valve to adjust the gas flow, pressure, temperature, etc. In fact, this is to meet the requirements of process and working conditions for gas flow regulation by artificially increasing resistance at the cost of wasting electric energy and money. This backward regulation mode not only wastes valuable energy, but also has poor regulation accuracy, which is difficult to meet the requirements of modern industrial production and services, and has serious negative effects. With the continuous improvement and development of frequency conversion technology in recent ten years. The performance of variable frequency speed regulation is becoming increasingly perfect, customized Electrostatic wet precipitator It has been widely used in AC speed regulation in different fields. It has brought considerable economic benefits to enterprises and promoted the automation process of industrial production.
