The pressure relief method of the tandem dust collector
With the continuous development of industrialization, the problem of environmental pollution is becoming more and more serious. In order to effectively control pollution, many enterprises have begun to use dust collectors for dust control. During the operation of the dust collector, the choice of pressure relief method is directly related to the performance and reliability of the equipment. This article will introduce in detail the pressure relief method and its characteristics of the tandem dust collector.
1. The structure and working principle of the tandem dust collector.
A tandem dust collector is a dust collection system consisting of multiple dust collection units, each of which is equipped with an independent pressure relief valve. By connecting multiple dust collection units in series, the air can be purified step by step, thereby reducing the emission concentration.
Second, the choice of pressure relief method.
1.Throttling and depressurizing.
Throttling and pressure reduction is a common pressure relief method that reduces pressure by setting a throttle orifice plate inside the dust collector. When the dust-laden gas passes through the orifice plate, the flow rate increases and the pressure decreases due to the sudden decrease in the flow area, so that the dust can be settled and separated. Throttling and pressure reduction have the advantages of simple structure and easy operation, but it is easy to cause secondary pollution.
2.Spray depressurization.
Spray depressurization is a form of pressure relief by spraying liquid into the dust collector to reduce pressure. During the spraying process, the liquid interacts with the dusty gas, which separates the dust particles from the gas. Spray pressure reduction can effectively reduce the dust concentration in the gas, but the nozzle needs to be cleaned and maintained regularly, otherwise it is easy to cause clogging.
3.Mechanical vibration relief.
Mechanical vibration relief is the use of mechanical vibration device to vibrate the inside of the dust collector, so that the dust accumulated inside the dust collector is loosened and discharged from the equipment. This pressure relief method can effectively improve the service life and reliability of the dust collector, but it requires regular inspection and maintenance of the mechanical vibrator to ensure its normal operation.
4.Sonic vibration decompression.
Sonic vibration relief is a type of pressure relief that vibrates dust and expels it from the equipment by emitting sound waves inside the dust collector. Sonic vibrators can generate high-frequency vibrations that loosen and expel dust that has accumulated inside the collector. Sonic vibration relief has the advantages of simple operation and easy maintenance, but it needs to be regularly inspected and maintained to ensure its normal operation.
III. Conclusion. The pressure relief method of the series dust collector is an important technology related to the performance and reliability of the equipment. In practical application, the appropriate pressure relief method should be selected according to different working conditions and dust properties. At the same time, in order to improve the service life and reliability of the dust collector, it is also necessary to regularly inspect and maintain the equipment to ensure its normal operation.
