When the special precipitator dust collector works in the stone factory, with the continuous filtration, the dust accumulation on the surface of the filter cartridge increases gradually, and the resistance of the dust collector gradually increases. When the set value is reached or the time is reached, the dust control instrument sends out the ash cleaning instructions, clears the dust on the surface of the filter and falls into the ash bucket, and the whole process is filtering, pulsing and blowing out.
The stone plant dust remover is suitable for the process recovery and dust removal and purification of the fine dust, and the emission concentration can be far lower than the state regulations.
The dust collector of the stone factory is a low energy dust cleaning and external filter bag filter. Its filter bag is flat bag, and the cross section shape of the filter bag is made into trapezoidal or wedge-shaped. Compared with the circular filter bag, under the same filter load per unit area of the filter, the area is small and the structure is compact, that is to say, the filter area can be arranged in a unit volume, which is a major feature of it. At present, it has been gradually popularized in the crushing and screening industry.
The stone plant dust remover is suitable for process recovery and dust removal purification of fine dust. It belongs to low energy dust cleaning and external filter bag filter.
advantage
(1) the central cleaning is adopted for the cleaning device.
(2) injection pressure has low pressure injection, pressure is less than 0.4MPA, high pressure injection, pressure is higher than 0.4MPA. The high pressure gas source has larger kinetic energy and less gas consumption, and the low pressure gas source has less kinetic energy and more gas consumption. The pressure of pulse gas source is high or low, so that the ash removal power is the same.
(3) the injection cleaning mechanism is divided into a venturi tube without a drain nozzle, a venturi tube with a drainage nozzle, and a venturi tube with a drainage nozzle.
(4) pulse jet cleaning is divided into on-line cleaning and off-line cleaning. By adjusting the parameters of the dust collector, the online and off-line cleaning can achieve the same cleaning effect.
