When the pulse bag type dust collector works normally, the dusty gas enters the ash bucket through the air inlet. Due to the expansion of the gas volume, some coarse dust particles fall into the ash bucket due to inertia or natural settlement, and most of the rest dust particles rise with the air flow into the bag chamber. After being filtered by the filter bag, the dust particles are retained outside the filter bag, and the purified gas enters the upper box through the filter bag. Then through the valve plate hole, exhaust outlet into, so as to achieve the purpose of dust removal. With the continuous filtration, when the resistance reaches the value, the cleaning controller issues the cleaning command to close the valve plate and cut off the filter air flow; Then, the cleaning controller sends a signal to the pulse solenoid valve. With the pulse valve, the high-pressure reverse air flow used for cleaning is sent into the bag, and the filter bag bulges and produces strong shaking, resulting in the dust on the outside of the filter bag to shake off and achieve the purpose of cleaning. Since the equipment is divided into several box areas, the above process is carried out box by box. When one box area is cleaned, the other box areas are still working normally, and the continuous normal operation of the equipment is normal. The reason why it can handle the concentration of dust, the key is that this strong cleaning time is short (0.1 ~ 0.2s).

function of cyclone ventilation will not only lead to a good reduction in the operation rate of dust removal equipment, but also harm the service life of dust removal bag. The dust removal equipment of air drying machine will cause condensate water in the dust collector bag due to ventilation, so that the dust removal equipment can not be all normal application. To deal with such problems, it is necessary to improve the design scheme and installation of dust removal equipment. Improve the sealing of cloth bag type dust collector.

1. Design and installation of long bag single pulse cloth bag type dust collector

Mechanical long bag single pulse cloth bag dust collector has a large volume, in order to better transport, generally choose the methods of disassembly, split shipment, spot assembly and so on. Poor installation on the spot is easy to lead to machine equipment left and right shift, forced installation is easy to cause partial deformation, welding asymmetry; After the machine and equipment are put into operation, under the synergistic effect of fan power, ash removal driving force and welding stress, the defect is easy to produce the aspect ratio stress, which may lead to partial cracking, resulting in ventilation of the machine and equipment. In the design scheme of dust removal equipment, in addition to taking into account the sufficient compressive strength and bending stiffness of the machine itself, the installation procedure should also be improved to reduce the accumulation deviation of installation as far as possible and improve the installation quality.

2, improve the sealing of mechanical long bag single pulse cloth bag type dust collector equipment

Improve the tightness of the manhole door: the design scheme of the rear cover plate of the manhole door should consider the requirements of compressive strength and bending stiffness. When making the door frame and the rear cover plate of the door should be flattened. In the assembly line, sealing rubber strips should be used to carry out the sealing, and the door should be clamped together with pressing blocks. The common sealing rubber strip structure has "U" type and "Y" type.

If the bag dust collector accumulates too much dust in the long term, the friction resistance inside the bag dust collector will expand, which will harm the actual effect of dust removal and the service life. Therefore, when the dust bag of the bag dust collector is found to have a lot of dust accumulation, the dust cleaning should be carried out. Dust removal equipment to clean up dust, not manual cleaning method, only by opening the equipment to rise ash removal, you can clean the dust on the machine equipment.
