Baghouse free Zhengzhou Pu Technology Co., Ltd. to provide! According to "baghouse classification and specification method," the national standard, bag filter is divided into five categories. Cleaning method is the primary symbol baghouse category: (1) Mechanical vibration class of the bag by mechanical means (including manual, electromagnetic or pneumatic means) generates vibration cleaning bag filter, there is room for work space presumptuous Two tectonic structure and suitable sub-chamber structure forms a continuous bag filter. (2) sub-room cleaning class to take sub-chamber structure, by means of the valve chamber switching airflow in the reverse flow, forcing the bag-shaped deflated or inflated and cleaning bag filter. (3) nozzle cleaning with high pressure air or compressor class provides cleaning airflow performed by moving the nozzle cleaning, jitter and distortion of the bag through the filter and bag filter cleaning (both presumptuous room structure). (4) vibration, cleaning and mechanical vibration with the class (including electromagnetic vibration or pneumatic vibration) and cleaning two kinds of cleaning methods and use of bag filter (both sub-chamber structure). (5) The pulse jet type powered by compressed air cleaning, use an instant release of the compressed air pulse jet bodies, secondary air injection to induce multiple high-speed bag, make a sharp bulging bag, carbon black plant bag Dust, rely on shock and vibration and reverse flow and cleaning bag filter. Boiler first start pre-coated baghouse ash in step 1, the first start is the most critical, because the bag is clean, bag filter maintenance, no protective layer of powder, it is vulnerable to dust, wear, fine sand or other penetration or material adhesion. Flue gas containing a considerable amount of time to start vapor and other condensable gases and the combustion of the fuel is not completely, the temperature of the beginning of the filter will be lower than the dew point temperature of water vapor, and therefore, when the temperature has not reached a stable operation do may protect the media is very important, pre-spray will be covered with a layer of ash on the filter surface to prevent moisture and cause blockages in the pre-coating process, the boiler must be offline. Need slaked lime or other validated pre-spray material following particle size: 75% less than 20μm50% less than 15μm25% less than 5μm2, open the inlet manual control valve. 3, the start of the pre-spraying dust, open each of the chambers of the wind poppet valve. 4, in the pre-coating process, timers and pulse valve cleaning all rooms should all off, to prevent the filter bag cleaning. 5, in which the inlet air control valve actuated suction fan case closed when the fan is working to maximum speed, slowly open the inlet valve to control 30% to 40%, dust bag machine, but do not let the induced draft fan overpower operation, the need for adequate air flow (per room 18000m3 / h) to prevent pre-coating material to fall down into the hopper. 6, the pre-spraying trucks or blower on precipitator inlet pipe nearby, where appropriate, the car delivery tube and pre-spray nozzle flue connection (if any) or open hopper Manhole. .7, Continued into the filter material injected into the pre-spraying until each chamber pressure drop reaches or exceeds 125Pa to 250Pa so far. It is more than an initial reading 125Pa to 250Pa. Observation of airflow or fan speed, to determine which 125Pa to 250Pa growth of water because the pre-filter coating on the cause, rather than the wind increases. 8, pre-spraying end, stop the truck blower system, remove the pre-spray nozzle, put on lid (cap) or cover Manhole. Note; After the pre-coating, bag filter machine works, not for fuel combustion in the bag before cleaning .9, after the pre-spray, we should start the boilers and dust removal system. Combustion of the fuel should be within 48 hours after the start of the pre-spray, spray pre-filter is approximately an hour.
