The wet electrostatic precipitator is a new kind of dust removal equipment used to treat micro dust and micro particles, major Boiler fan It is mainly used to remove dust, acid mist, water droplets, aerosols, odor, PM2.5 and other harmful substances in humid gases, and is an ideal equipment for controlling atmospheric dust pollution. The wet electrostatic precipitator is usually referred to as WESP, which has the same basic principle as the dry electrostatic precipitator. It goes through three stages: charging, collection and dust removal. The principle of wet electrostatic precipitator is the same as that of dry electrostatic precipitator, Hubei Boiler fan The dust is charged by high-voltage corona discharge, and the charged dust reaches the dust collecting plate/tube under the action of electric field force. The dry electrostatic precipitator mainly deals with dry gas with very low water content, while the wet electrostatic precipitator mainly deals with wet gas with high water content or even saturation. There is a big difference between WESP and DESP in the way of removing the dust collected on the dust collecting plate/pipe. The dry electrostatic precipitator generally uses mechanical rapping or acoustic cleaning to remove the dust on the electrode, while the wet electrostatic precipitator uses regular flushing to remove the dust along with the flow of flushing fluid

9. Since the flow, total pressure, main shaft speed and shaft power of the fan have a fixed relationship, the main shaft speed should not be changed when the motor capacity does not change. If the main shaft speed increases, the motor may be burned due to overload. The motor power used by the fan refers to the power not required when the air inlet and outlet are fully open in terms of mechanical losses and due reserves under a specific mine. If the outlet or inlet of the fan is not connected to the pipeline or is idle without external resistance, the motor may also be burned out. For safety, a valve shall be added to the outlet or inlet pipeline of the fan, and it shall be closed when starting the motor. After turning, the valve shall be slowly opened until the specified working condition is reached, and attention shall be paid to whether the current of the motor exceeds the specified value. High power motors must be started in proper ways, such as voltage reduction, frequency conversion, etc.

Fans can be classified into several types according to the materials used, such as iron shell fans (ordinary fans), glass fiber reinforced plastic fans, plastic fans, aluminum fans, stainless steel fans, etc. Boiler fan company In the direction of gas flow. Fans can be classified into centrifugal, axial, diagonal (mixed flow) and cross flow fans according to the direction of gas flow. (1) Centrifugal fan. The airflow enters the impeller of the fan axially and flows mainly along the radial direction. This type of fan is made according to the principle of centrifugal action, and its products include centrifugal fan, centrifugal blower and centrifugal compressor. (2) Axial flow fan. The airflow enters the impeller of the fan axially and flows approximately along the axis on the cylindrical surface. Such fans include axial fans, axial blowers and axial compressors. (3) Rotary fan. Hubei major Boiler fan Use the rotor rotation to change the air chamber volume to work. Common varieties include Roots blower and rotary compressor.

Emergency stop: major Boiler fan company In case of one of the following situations during the unit commissioning, emergency shutdown shall be carried out immediately. The emergency stop operation is to press the stop button of the main motor, and then carry out the remedial work after the shutdown; The centrifugal fan suddenly vibrates strongly and has exceeded the trip value; There is scratch or abnormal friction sound inside the machine body; major Boiler fan Smoke occurs at any bearing or seal, or the temperature of a bearing rises sharply to the alarm value; When the oil pressure is lower than the alarm value and cannot be restored to normal; The liquid level in the oil tank is low, and there is suction phenomenon; When the axial displacement value increases significantly and reaches the alarm value;

Hubei Boiler fan company 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. major Boiler fan 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!

Main working principles of wet electrostatic precipitator: major Boiler fan 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, Hubei Boiler fan 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, Boiler fan company 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.
