The wet electrostatic precipitator is a new kind of dust removal equipment used to treat micro dust and micro particles, major Electrostatic wet precipitator 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, Zhengzhou Electrostatic wet precipitator 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

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 Electrostatic wet precipitator 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;

According to the report data released by the Global Wind Energy Council, the new installed capacity of global wind power in 2014 was 51477MW, up 44% year on year, and the cumulative installed capacity exceeded the threshold of 50GW for the first time. All data set new world records. China's wind power industry has driven global growth. In 2014, China's new installed capacity of wind power was 23350500 kilowatts, 45.1% higher than that of the previous year, major Electrostatic wet precipitator The cumulative installed capacity has reached nearly 115 million kilowatts, of which the grid connected capacity is nearly 100 million kilowatts, accounting for 7% of the total installed power generation capacity. In addition to the strength of wind power itself, the recovery of the wind power industry has also contributed to the decline of coal prices. The decline of fuel costs has led to the profitability of most power enterprises hitting a new high in 2014, Electrostatic wet precipitator manufactor This can expand the scale of wind power construction and accelerate the payment of unit arrears. As a result, the performance of wind power equipment manufacturers was in full swing in 2014, the market concentration was further improved to the top eight complete machine enterprises, and China's wind power industry basically ended the situation of low price competition. The wind power industry generally believes that the wind power industry will enter a new normal of stable growth in the future. In the next five years, the annual new installed capacity may reach at least 20 million kilowatts, and there is still a bottleneck for developers to improve their profits.

Gas compression and gas transmission machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy and transports gas. The main structural components of the fan are impeller, casing, air inlet, support, motor, pulley, coupling, silencer, transmission parts (bearings), etc. major Electrostatic wet precipitator The unpowered fan uses the air thermal convection caused by the natural wind force and the indoor and outdoor temperature difference to drive the turbine to rotate, thus using the centrifugal force and negative pressure effect to exhaust the indoor stale hot air. Zhengzhou Electrostatic wet precipitator manufactor The fan is related to the transmission and distribution energy consumption of the system, and is a very critical part of building energy conservation. According to the fan inspection conducted by the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years, many fans have problems under rated conditions, so it is necessary to produce and manufacture fans in strict accordance with product standards. major Electrostatic wet precipitator At the beginning of the fan operation, the vibration of the bearing is very small, but with the extension of the operating time, the dust in the fan will be unevenly attached to the impeller, gradually destroying the dynamic balance of the fan, making the bearing vibration gradually increase. Once the vibration reaches the maximum allowable value of 11mm/s of the fan (the maximum allowable value expressed by the amplitude value is as follows), The fan must be shut down for repair (dust accumulation shall be removed and dynamic balance shall be redone). Because it is very dangerous at this time, users must not use it forcibly. When the fan vibration is close to the dangerous value, the vibration measuring instrument will give an alarm.

Zhengzhou major Electrostatic wet precipitator Forecasts from foreign markets. The member units of China General Machinery Fan Industry Association exported 7969 fans in 2000, with the export delivery value of 81.157 million yuan. From 1991 to 2000, the total number of exported fans was 72876, and the total value of export delivery was 747.26 million yuan. Electrostatic wet precipitator manufactor The trend of global economic integration is becoming more and more obvious. The economies of all countries will further depend on each other. International economic cooperation and exchanges will become closer and closer. The international market is at a stage of significant intersection and integration. At the same time, the pace of global industrial restructuring is accelerating, and significant progress has been made in the scale and depth of international division of labor. Developed countries continue to shift industrial production to capital intensive and technology intensive industries, and labor-intensive products are transferred to developing countries and regions. This provides a good development opportunity for China to play its own advantages and enter the international market. Since the 1970s, China has introduced foreign advanced technology of centrifugal compressor, which has improved the product grade through digestion, absorption and innovation. As long as the quality and delivery time are guaranteed and the price advantage is used, it is competitive internationally. Especially after China's entry into WTO, it is entirely possible to increase the fan export. From the historical analysis, the main export varieties are small and medium-sized fans and fan accessories. The main gap between domestic enterprises producing such fans is that the surface quality cannot meet the export requirements. If the appearance quality is improved and the price is favorable, the prospect in the foreign market is broad. From 1991 to 2000, the fan exports of small and medium-sized fans were not stable enough, and there was no obvious growth trend. However, with the continuous progress of technology, it is expected that the export volume of such fans will continue to increase, and it is predicted that the annual average growth rate will be about 5% on the basis of 2000. major Electrostatic wet precipitator The export of centrifugal compressors and blowers increased significantly from 1991 to 2000, reaching 870000 sets in 2000. The main exporting countries are India, Pakistan, Iran, Vietnam and other developing countries. It is expected that this trend will continue to develop, reaching 1 million units per year.
