1. When the surface of the filter is not very dirty, take it outside and blow it with air to blow away the invisible dust. 2. When the surface is very dirty, it needs to be washed with water. Put the reference water in the tank in the water making room, and after the detergent is diluted, put the filter in the water. Rinse, rinse with clean water until the water is clear, take out the empty dry water, spread it flat on a shelf to dry in the shade, cool in the sun, and turn on both sides frequently to speed up the drying speed. 3. Use a rag to wipe the air conditioner surface, accessory wires, and meters to make the equipment cleaner and brighter. 4. Use a cloth and detergent to wipe off the oil and glue on the equipment, and then wipe it clean with drinking water without leaving any traces. 5. After replacing the primary and middle-efficiency #filters, we clean the various parts in the air conditioner, wipe off dust, dirt, and oil stains, and then install the middle-efficiency #filter. 6. The inside of the system should be cleaned once every half a month, first wipe the inside with a damp cloth, and then use a dry cloth to clean it all. 7. When replacing the #filter, wipe the four frames and the periphery where the #filter is installed with a damp cloth, repeat three times, and install it immediately after wiping. The #filter should be unpacked on site and installed immediately after inspection to prevent dust from falling into the #filter.

  Electrostatic precipitator(ESP) is a dust removal device that uses electrostatic force to separate particles and airflow. Compared with other dust removal equipment, the electric precipitator(ESP) has low energy consumption, pressure loss is generally 200-500Pa, dust removal efficiency can be higher than 99%, and the processing flue gas volume can reach 105-106m3/h. It can also be used for high temperature and Strongly corrosive occasions. The disadvantages of electrostatic precipitators(ESP) are high investment and high technical requirements for manufacturing, installation and operation management.   The working principle of the electrostatic precipitator(ESP) includes three basic processes: dust charging, migration of charged particles, deposition and dust removal on the surface of the dust collector.

Mainly refers to the dust removal equipment designed by the application of dust inertia and gravity, such as gravity sedimentation chambers, inertial dust collectors, cyclones and other high-concentration dust collectors, etc., mainly used for the separation or concentration of high-concentration coarse-particle dust . The gravity settling chamber is a dust removal device that allows dust particles to settle and separate from the airflow by gravity. The main advantages of the gravity sedimentation chamber are simple structure, low investment, low pressure loss and easy maintenance. But its large size and low efficiency can only be used as a pre-dust removal device for high-efficiency dust removal to remove larger and heavier particles. The inertial dust collector is a dust removal device that changes the direction of the airflow sharply and uses the inertial force of the dust particles to separate them from the airflow. In terms of it, the higher the airflow velocity, the greater the angle of the airflow direction change, the more the number of changes, the higher the purification efficiency, and the greater the pressure loss. The inertial dust collector is used to purify metal and mineral dust with large density and particle size, and has a high dust removal efficiency. The cyclone dust collector is a dust removal device that rotates the dust-containing airflow and uses centrifugal force to separate particles from the airflow. The dust particles contained in the airflow are subjected to centrifugal force to settle on the outer wall during the rotating movement process, and the dust particles that reach the outer wall fall into the ash hopper along the wall under the combined action of the airflow and gravity.

Precautions for installation of dust collector filter bag:   1) New technology and old dust clothfelt filterbags should not be mixed to avoid the difference in damage time from affecting the normal operation of the dust removal equipment.   2) The aging of clothfilter sleeves. Mainly due to the following reasons, it is necessary to investigate the cause, take elimination measures and replace theneedle punched feltdust filter bag.①It hardens and shrinks due to abnormal high temperature;②Reacts due to contact with acid, alkali or organic solvent vapor;③Reacts with moisture.   3) The filter clothfabricsshould not be hung too loosely or too tightly. Too loose and easy to accumulate dust, and too tight to be easily damaged.   4) After replacing the clothsock sleeves for dust collection, blow it with compressed air first, and then check for any holes. After the holes are repaired, they will be kept for replacement. If the cloth bag is stuck with dust, rinse it with water, and leave it to be replaced after it has dried.   5) The clogging of the dust bag for baghouse. When thecement industrial non woven dustclothfilterbag is clogged, the resistance increases, which can be reflected by the increase in the reading of the differential pressure gauge. The clogging of the cloth bag is the main reason for the phenomenon of cloth bag filter wear, perforation, falling off and so on. For the cause of the clogging of the dustremovalbag for dust collection, check and repair according to the following table. Generally, the following measures are taken:①Temporarily strengthen dust removal to eliminate the clogging of the cloth bag;②Partially or completely replace the100% ptfe cloth filter socks;③Adjust the installation and operating conditions.   The calculation formula for the price of dustfilter socks&sleeves:   We will show you how to calculate the price ofdust collector filter sleeves with the most commonly used materials.   The formula is: (caliber x3.14+0.03) x length x unit price. In this way, the price of a cloth bag can be calculated.   The caliber here refers to the opening of thecell plate you installed, and the unit price refers to the price per square meter (the price is different for different manufacturers according to different materials)   Application range of dust bag sleeves for asphalt mixing industry:   Flue gas treatment and dust removal systems in ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, etc.   Waste incinerators, coal-fired boilers, fluidized bed boilers and other flue gas filtration.   Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites.   Smelting flue gas filtration of aluminum electrolysis, lead, tin, zinc, copper and other rare metals, recovery of fine materials, separation of liquid and solid.   Liquid-solid separatio...

Sectional shape of dust filter bag According to the cross-sectional shape of the filter bag, it is divided into three types: round, flat and special. 1. Round: The dust filter bag is cylindrical. Its specifications are expressed by diameter × length, namely D × L (mm); 2. Flat shape: The filter bag of the dust collector is flat, including rectangular and trapezoidal, and its specifications are expressed by perimeter × length, namely P × L (mm); 3. Abnormal shape: the filter bag with a special shape, and its specifications are expressed by the characteristic parameters of its structure. Filter method According to the filtration method, it is mainly divided into two types: internal filtration and external filtration. 1. Internal filter type dust bag: After the dust-containing gas is filtered through the inner surface of the filter bag, the dust is blocked on the inner surface of the filter bag. This filtering method is called the inner filter; 2. External filter type dust collector cloth bag: After the dust-containing gas is filtered by the outer surface of the filter bag, the dust is blocked on the outer surface of the filter bag. This filtering method is called an external filter. Normal temperature, medium temperature, high temperature, ultra-high temperature (metal 316L) Normal temperature generally does not exceed 90 degrees, medium temperature is generally about 120 degrees, and high temperature is generally about 280 degrees.
