Mid-frequency furnace bag filter design skills

The working principle of medium frequency bag pulse dust collector
1. Filtration: Dust-laden gas enters the air intake chamber under the action of the main fan. Due to inertia and impact, some of the coarse dust directly falls into the bottom of the hopper. Dust-laden gas is evenly distributed to the chambers by the flow guiding device, filtered into the clean air flow through the inner surface of the filter bag, and discharged from the main fan through the exhaust pipe above the chamber. The negative pressure operation of the pulse dust collector, the dust concentration of the purified gas is less than 50mg/Nm 3 , which is lower than the national standard.
2 Ash removal and electronic control: After the dust collector is running, the dust layer attached to the inner surface of the dust bag will be thickened. When the resistance reaches a certain value (or a certain time), the control system will switch the electric valve body, due to the negative pressure, The natural air or recirculating air is sucked into the filter chamber, the filter bag shrinks, and vibration is generated. The dust is removed, and the dust is peeled off and dropped into the ash hopper. The spiral conveyor and the ash discharge device discharge the dust. The entire dust removal process is divided into chambers and dust collectors are operated in turn using advanced programmable controllers with differential pressure, timing, and manual three control methods. Control cleaning, control system control of three-way tangential valve, pneumatic components, cold air valve, and ash discharge valve, alarm on sensing elements such as temperature, material level, etc., and cold air system, bypass system, main wind The agency started interlocking control. In this way, while ensuring the cleaning effect, the service life of the dust removal bag is maximized, and the operating efficiency of the dust removal device is further improved. The bag filter is a filter-type dust-removing device based on the filtration principle. The organic dust or inorganic fiber filter cloth is used to filter the dust out of the gas.
Bag filter structure: dust collector hopper, inlet and outlet duct, filter room (middle and lower box), clean room, filter bag and frame (bag cage bone), manual air inlet valve, pneumatic butterfly valve, pulse Ash removal agencies.
1. Bag filter body: shell, cloth bag assembly, exhaust pipe, back blowing pipe, air inlet pipe, manhole door, unloading device, bracket, various valves, etc.
2. The electrical control part of the dust collector: Adopt advanced digital PLC program control technology (the main components use ABB).
3. The main fan, ash conveying device and external inlet and exhaust pipes matched with the bag filter.
