For the normal operation of single-machine dust collector, it is very important to pay attention to and repair it. It is very important to find out the doubts of single-machine dust collector in time. Customers must check and repair it when they use it. Only in this way can the single-machine dust collector work normally. For the convenience of repairing, customers must prepare a ladder, lighting equipment, and prevent some poisonous and harmful gases from entering the system during the operation of single dust collector. When the single dust collector stops working, they should also use air to replace the gases in the system. If they think that harmful gases still exist, they should use the instrument to check. Acknowledging that the rear can operate, but it is not suitable for single operation. Otherwise, if the doubt can not be found in time, it will constitute a big trouble. When repairing the interior of a single dust collector, it is necessary to select some corrosion-resistant coatings to prevent corrosion. Under normal conditions, because the purified gas is mostly acidic, epoxy resin-based acid-resistant coatings are often used. The gap of the box body is usually padded with rubber, rubber pad, asbestos pad, etc. to prevent gas leakage. With the extension of time, some gaskets will become old, degenerate, damage and fall, which will aggravate the air leakage. When repairing, it is found that the above phenomena should be taken seriously, replaced or plugged, and air leakage should be prevented as far as possible. Epoxy resin and leak-proof cement are good data in the existing leak-proof materials guess. If the holes are formed by dust erosion, they are repaired and welded.

The bag filter belongs to the mechanical dithering dust collector, which collects and separates dust particles from the airflow. It adopts the mechanical vibration dust removal equipment. The machine can be equipped with shot blasting machine, sand blasting machine, crusher, sand screening machine, sand mixer and other equipment with high dust concentration. Practice has proved that the bag filter runs steadily, has low noise, high dust removal efficiency and is convenient for operation and maintenance. The blower of bag filter adopts centrifugal blower, which has large air volume and high air pressure, and adopts silencing measures with low noise. The filter adopts flat cloth bag group, each bag is equipped with spring wire mesh, and the filtering effect is good. The dust cleaning mechanism uses the motor to drive the eccentric wheel and connecting rod to make the bag shake and dust on the surface of the filter bag. The bag filter has an overhaul door to facilitate overhaul and bag replacement. Mainly by the shell, high-pressure fan, filter bag, dust collection drawer, abdominal cavity, air intake pipe, air duct, circuit devices and other components. It is mainly suitable for dust removal and cleaning in foundry industry, ceramics industry, glass industry, refractory materials, cement building materials, grinding wheel manufacturing, chemical reagent processing, mechanical processing, mining metallurgy, machine tools, grinders and other industries. Its dust removal efficiency is over 99.5%. The bag filter is a dry filter. It is suitable for trapping fine, dry and non-fibrous dust. The installation and operation quality of bag filter play an important role in the normal operation of production line. Therefore, attention should be paid to the installation, construction, operation and maintenance of bag filter in order to ensure the stable and good operation of bag filter and ensure the smooth operation of production. Bag filter is mainly used in cement mill, kiln tail and other systems, and plays an important role in production. Some bag filter dust removal systems can not start up in operation, mainly manifested in the following aspects: fan rotation does not smoke, electric furnace hood suction is insufficient, smoke escapes, three chimneys still smoke; hood, cooler, dust collector bag and induced draft fan are not matched, the system capacity is generally inadequate; hood, cooler, bag filter and induced draft fan have structure. It is unreasonable and has insufficient capacity; it is not standardized to produce dust; it is disorderly to dispose of smoke and dust, and the second dust can be seen everywhere; there is no scientific management system to ensure orderly operation. Bag filter has many advantages, such as high dust removal efficiency, convenient operation and maintenance, and can meet the discharge standards. It is accepted by more and more dust control systems. But bag filter is not available anywhere. It needs special attention when used in the following working conditions. 1. Where the temperature is particularly high If the temperature exceeds 350 C, the bag filter can not be used directly, because the temperature is too high for the bag to bear, it will be burned, even if using the high temperature dust bag, it can not withstand the high temperature of 350 C. Cooling measures should be taken before high temperature dust enters the bag filter. 2. Where the humidity is too high It is not suitable to collect smoke with too much oil, and the humidity is too high. Too much oil in the flue gas often causes the filter bag to bind and clog the filter material; if it is a little humid, the filter bag in the bag filter can choose water-repellent and oil-proof filter bag, or the bag filter can take thermal insulation measures to ensure that the moisture in the gas will not condensate. Start-up conditions of bag filter 1. Start the air compressor fan, the fan works normally, and adjust the pressure of the separator chamber of the dust collector from 0.2 to 0.4 MPa. 2. Dust collector flue gas inlet temperature 120-180 C 3. The dust collector can receive flue gas only after the boiler has withdrawn oil and put coal into stable combustion. 4. Make sure that the bypass door of the dust collector is closed tightly and the baffle door of the entrance and exit of each dust collector is flexible. 5. Compressed air pressure meets the requirements, put into the ash removal system one hour ahead of schedule, and start the small dust collector on the ash depot. 6. Put into the ash hopper heating device 8 hours before starting the dust collector. 7. The pressure and quality of compressed air to ash cleaning system are qualified. 8. Compressed air pipeline and oil discharge and drainage valves of gas storage tanks are opened. There is no oil accumulation and water accumulation in oil discharge of pipelines and gas storage tanks. The following points should also be paid attention to in processing and manufacturing. 1. The connection between the filter bag and the flooring board should consider not only the convenience of disassembly and assembly when changing the bag, but also the tightness of air leakage, preventing short circuit of air flow and reducing dust removal efficiency. 2. When external filtration is used, the cage bone surface supporting the filter bag is smooth and smooth, and sharp bulges or corner burrs are not allowed to prevent puncture or excessive wear and tear of the filter bag, resulting in short-circuit air flow and reducing dust removal efficiency. 3. When internal filtration is adopted, the upper suspension mechanism and the lower flooring board should be centered to ensure that the filter bag has enough verticality and equal strip spacing; the lifting tightness of the filter bag should be kept consistent to prevent the filter bag from transitional deformation and affect the normal operation of the dust collector. 4. Pulse valves, solenoid valves and pulse control instruments for pulse ash cleaning are required to have good performance, flexible operation and long-term continuous operation. 5. The reversing valve and its control device with air back suction or air back blowing for ash removal are in place, flexible in action, light in operation and tight in closing.

1. High dust removal efficiency: Especially for fine dust, it has high efficiency. If sufficient attention is paid during design and maintenance management, the dust removal efficiency is not difficult to hit 99.9%. 2, strong adaptability: can capture dust of different nature. For example, for high specific resistance dust, the use of a bag filter is superior to an electrostatic precipitator. In addition, when the inlet dust concentration changes over a relatively large range, there is little effect on the efficiency and resistance of the precipitator. 3, flexible use: processing air volume can be hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour, or even larger. It can be made into a small unit directly in the room or near the machine tool, or it can be made into a large dust room, the so-called "bag room". 4, the structure is simple: You can use a simple bag to remove dust according to local conditions. A more efficient pulse jet bag filter can also be used when conditions permit. 5, stable work: easy to recycle dry dust, no sludge treatment, corrosion and other issues, easy to maintain.

Because the pulse bag type dust collector has strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small floor space, stable and reliable operation, and good economic benefits. It has become one of the most dust-removing devices in the market. When the pulse bag type dust collector equipment works normally, the dust-containing gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, a part of the coarse dust particles fall into the ash hopper due to inertia or natural settlement, etc. The cleaning command first closes the lifting valve plate, and the dust particles are retained on the outside of the filter bag. The purified gas enters the upper tank from the inside of the filter bag, and is discharged into the atmosphere through the valve plate hole and the exhaust port, thereby achieving dust removal. the goal of. The filter airflow is cut off, and the cleaning controller sends a signal to the pulse solenoid valve. As the pulse valve sends the high-pressure reverse airflow used for cleaning into the bag, and generates strong vibration, when the box area is cleaned, the remaining box areas are still In normal work, the continuous operation of the equipment is guaranteed. The reason why it can handle high concentration of dust causes the dust outside the filter bag to shake off and achieve the purpose of cleaning. Since the equipment is divided into several box areas, the filter bag quickly swells, and most of the remaining dust particles rise into the bag chamber with the airflow. After filtering through the filter bag, as the filtration continues, the dust collector resistance also rises, when the resistance reaches When the value is certain, the above process is carried out box by box. The key point is that the cleaning time required for such strong cleaning is extremely short (only 0.1 to 0.2 s is required for spraying once). After the cleaning is completed, the dust collector works normally.
