The advancement of the manufacturing process technology of the Explosion-proof Pulse Valve and the formalized manufacturing process are the keys to the continuous progress of the Explosion-proof Pulse Valve. Its production has formed a production line model, and each production process can be strictly controlled layer by layer. To achieve automated and semi-automated welding, as well as mold-based and uniform processing of general parts. The establishment of the Explosion-proof Pulse Valve standard system. The standardized system standard of the Explosion-proof Pulse Valve has been customized. The Explosion-proof Pulse Valve is also produced in accordance with the standardized requirements. The progress of the standard system also leads the progress of the dust collector.

The technical requirements regarding the principle, structure, precautions for use and operation and maintenance of auxiliary equipment of the Explosion-proof Pulse Valve, so that the operators can correctly understand the use of this type of dust collector for debugging and use.

The Explosion-proof Pulse Valve is composed of the upper box, the middle box, the ash hopper, the deflector plate, the bracket, the filter bag assembly, the injection device, the offline valve, the ash discharge device, as well as the detection and control systems, etc. The entire dust collector also includes auxiliary equipment such as maintenance platforms, lighting systems, and maintenance power supplies.

The dust collector uses filter materials to capture dust particles in the flue gas. The ability of the filter material to capture dust particles determines the dust removal efficiency of the dust collector. Therefore, the entire process flow of the dust collector can be simply described as maintaining a large ability of the filter material to capture dust particles by controlling the resistance of the dusty airflow passing through the dust collector. This control is to periodically clean the bags to prevent excessive airflow resistance.

All flange connections of the dust collector should be lined with sealing materials for sealing. All manhole covers and inspection doors should be pressed tightly. There should be no missing sealing strips and no air leakage.

Before starting the induced draft fan, the lift valve or bypass valve should be inspected. At least one of them should be in the open position. Prevent starting the fan when both the lift valve and the bypass valve are in the closed position. This will seriously damage the motor as well as the lift valve and the bypass valve! Before starting the dust collector, it is necessary to do a good job in cleaning and inspecting the dust collector.

After startup, the dust collector will filter the dusty gas to achieve the dust removal effect, and the dust cleaning process will be carried out in the online state. Generally, the good performance of a dust collector is indicated by the pressure drop of the dust removal system.

The processing air volume determines the specification size of the Explosion-proof Pulse Valve. Generally, the processing air volume is the working condition air volume. When designing, attention should be paid to the application site of the dust collector and the flue gas temperature. If the flue gas treatment temperature of the Explosion-proof Pulse Valve has been determined and the gas is cooled by the dilution method, the treatment air volume also needs to consider increasing the volume of diluted air.

Considering the future process changes, the design value of the air volume should increase the safety factor by 5% to 10% on the basis of the normal air volume. Otherwise, once the process is adjusted and the air volume is increased in the future, the filtration speed of the Explosion-proof Pulse Valve will increase, thereby increasing the equipment resistance and even shortening the service life of the filter bag. It will also be the cause of a sharp increase in the frequency of other faults. However, if the safety factor is too large, it will increase the investment and operating costs of the dust collector.

The filtration air velocity varies greatly due to the form of the Explosion-proof Pulse Valve, the type and characteristics of the filter material. Once the processing air volume is determined, the filtration area can be decided according to the determined filtration air velocity.

For high-temperature gases, to cool them below the temperature that the filter material can withstand, there are various cooling methods, such as natural duct cooling, forced air cooling, and water cooling, among which the more typical ones include natural air duct cooling, forced air cooling, and water cooling. The specific design and selection can be based on different processes, cooling temperatures, and layout size requirements.

Except for the circumstances, the gases processed by the Explosion-proof Pulse Valve are mostly ambient air or flue gas from furnaces and kilns. Under normal circumstances, the design of the Explosion-proof Pulse Valve is calculated based on the processing of air. The composition of the gas is only considered when parameters such as density, viscosity, and mass heat capacity are related to the calculation of the fan's dynamic performance and pipeline resistance, as well as the design of the cooling device.
