LMC long pulse dust collector bag and low long bag low pressure pulse bag filter dust bag pulse marks the successful development of technology has entered a new stage. This equipment has been in EAF, BOF, blast furnace gas purification, coal preparation, carbon black, fire-resistant, aluminum electrolytic, aluminum and zinc smelting and other areas used currently at a faster rate promotion. Description: LCM developed low-voltage pulse jet bag filter is summed up in the long baghouse on the basis of a variety of a new, efficient bag filter. It uses off-line low-pressure pulse cleaning technology to prevent reattachment of dust and loss of control, and enhance the cleaning effect of the bag, improved filtration rate, save energy and prolong the cleaning filter bag life. ESP uses PLC programmable logic controller, automatic control cleaning, ash the whole process. Thus, the dust is a process air flow, cleaning effect, high collection efficiency, reliable operation, easy maintenance, small footprint of large dust removal equipment. How it works: The dust is mainly composed of ash bucket, filter chamber, the net chamber, stand, lifting portion of the valve, jet cleaning devices and other components. Work, dust and gas from the duct into the hopper. Large dust particles directly into the bottom of the hopper, the smaller dust into the filter chamber with the air turning up, and was retained on the outer surface of the bag, clean the flue gas into the bag, and the bag and clean gas chamber by into the wind down, discharged from the exhaust port. With the continuous filtration, an outer surface of the dust filter bag is increasing, the device resistance rise. When the resistance of the device up to a certain value, should be cleaning operation, remove the bag surface fouling. Features: 1 ﹑ low-pressure pulse-jet technology, high cleaning efficiency and low energy consumption. Using the straight-pressure pulse valve. Injection pressure only 0.2 ~ 0.4MPa, low resistance, opening and closing fast, strong cleaning ability. Due to the cleaning effect, long cleaning cycle, reducing energy consumption blowback gas. 2 ﹑ pulse valve long life and reliability. Due to the low injection pressure, low pulse valve diaphragm pressure and impact force when opening and closing. At the same time due to the longer cleaning cycle, the pulse frequency and a corresponding reduction in the valve opening, thereby extending the life of the pulse valve, improves the reliability of the use of the impulse valve. 3, equipment running resistance is small, the general design resistance 1100Pa, the actual running resistance does not exceed 1200Pa, good injection effect. 4. bag easy assembly and disassembly, fixed and reliable manner using the upper pumping equipment, when changing bag from dust bag net gas chamber out of the skeleton, the dirty bag into the hopper. Remove from the hopper into the hole. Improve the environment for bags. Bag by bag of elastic ring rose flower plate fixed on the hole, fixed firmly, sealing well. The main features of the technology: 1 bag long. Generally reach 6-8 meters, is the traditional use of pulse jet bag filter bag 3-4 times the length, so small footprint; 2, injection pressure is low. As a result of straight-fast pulse valve open and close rapidly, their resistance is small, therefore, so long bag, injection pressure only 0.15-0.25MPa, you can get a good cleaning effect; 3, the cleaning ability strong. Strength cleaning bag to measure the gravitational acceleration g, while the use of anti-hair cleaning, cleaning intensity usually 35g, while the low-voltage pulse-jet cleaning mode allows the bag strength of 60 -200g. Thus, the low-pressure pulse cleaning strength is ten times the number of anti-hair; 4, filtered large load. Due to strong cleaning guaranteed, even at high operating precipitator filtration velocity, the resistance is not overrun. On the same occasion to use, low-voltage fast pulse baghouse filtration velocity reverse air baghouse is usually higher than the filtration velocity, so the same filter area, low pressure fast pulse jet bag filter with greater air volume; 5, running low energy consumption. Due to a significant reduction in injection pressure, and the cleaning method using fixed-pressure control mode, so that the cleaning power consumption is greatly reduced, and as a result of a thorough cleaning, the bag surface fouling thin, so the device resistance is lower than the anti-hair bag dust, so the system main motor power can be reduced by about 20%; 6, small maintenance workload. Due to the large pulse valve borne by cleaning area, number of pulses of the pulse valve with respect to the conventional bag filter is greatly reduced, because the diaphragm to improve the quality, reduce the injection pressure, the pulse valve diaphragm significantly improved service life, reduce maintenance workload. 7. Check and replace the filter bag convenience. Anti-Hair baghouse for bags, the operator need to go inside the box, on the bag, bind, operating environment is very bad. Long bag low pressure fast pulse jet bag filter bag by bag installation is elastic up the bag ring embedded in the flower board, no banding, and without bolts and other fittings. Side air bag when the net change in the flower people side panel, brief contact with the dust bag, changing bag work is very simple, eliminating the heavy labor, but also improve the operating environment for bags. 8, of the ground is extremely small, low investment. Because of the long bag and filter load is high, the same flue gas treatment filter area is less than the required anti-hair baghouse, which equipment, compact structure, less steel consumption, low cost equipment.
