This series of pulse bag dust collectors are widely used in metallurgy, steel, cement, and electric power industries. The structure of the pulse dust collector has its own characteristics, which improves dust collection efficiency and adaptability, and extends the service life of the filter bag. After years of production practice, the equipment operates stably, requires little maintenance, and has a wide range of combinations, and is well received by users.
This series of products can be widely used in dust collection systems for dust and smoke in asphalt mixing plant crushers, mills, dryers, furnaces, etc. The dust collector bag is generally made of polyester needle felt, and the allowed operating temperature It can reach ℃. If the inlet air temperature is higher than the allowable temperature of the above filter material, cooling measures should be taken before the exhaust gas enters the dust collector.
The pulse dust collector can be combined with a variety of dividers of different specifications according to the solenoid valves of different specifications. This series of dust collectors can operate under negative pressure or positive pressure without any change in its body structure. The dust collection efficiency reaches more than .%, and the purification Gas dust concentration &;/, if this series of dust collectors are used in cold areas or when the flue gas is below zero, an insulation heating device must be added, and the shell must be changed accordingly.
Structure and working principle:
Structure of pulse jet bag dust collector:
The equipment mainly consists of the following parts:
() Box: including bag chamber, pre-dust collection chamber, Clean air chamber, porous plate, filter bag, filter bag frame. The cabinet is designed to withstand pressure.
() Injection system: including main air pipe, injection pipe, pulse valve, and controller.
() There are two forms of ash hopper and ash discharge part: one is that the ash hopper is directly connected to the ash discharge valve, and the other is that the ash hopper is connected to the ash discharge through conveying equipment.
Working principle:
Dust-containing gas enters the enlarged hopper of the dust collector for pre-dust collection, and is evenly distributed between each filter bag through the guide plate, and the dust is retained on the surface of the filter bag. To ensure that the resistance of the equipment does not exceed the limit, the high-pressure gas generates pulse jets through the electromagnetic pulse valve, causing the compressed air in the air bag to be ejected from the holes of the blow pipe (called primary air) through the Venturi tube to induce the surrounding air several times the primary wind (called secondary air). Wind) enters the filter bag, causing the filter bag to expand rapidly in an instant, and shakes off the dust with the reverse effect of the air flow, achieving the purpose of dust cleaning. Microcomputer automatic control device is used to adjust the cleaning cycle and pulse injection time at will according to the dust concentration, so that the dust collector can operate within a certain resistance range.
When changing the bag of this dust collector, just open the top bag changing cover and directly pull out the filter bag. Maintenance is simple and convenient.
