Gas dryer baghouse dust control
Wind. The filter in use, it has been running with the host, the chimney exit determined by the environmental protection department of Huaibei City, emission concentrations were 50mg / n ~ below. Good closed the entire system, reducing air leakage, so much improved stove ventilation, air temperature rise, water down the material, and production increased. Ventilation and dust collection systems as well, meet the design requirements, the drying workshop clean and tidy, clean and bright work. HKD new dryer baghouse has achieved good economic benefits, significant environmental benefits, and social benefits. The filter equipment has been running with the host, the use of more than three years Break bag was not found, no replacement had a spare. 6.2 Economic Analysis HKD170-4 type bag filter a total investment of 28 million, including installation costs, holding costs, construction costs and costs of non-standard pipe. Inlet dust concentration to 30g / n ~ design, dust removal efficiency of 99.86. Recovery of 85 yuan per ton of dust materials,[link widoczny dla zalogowanych], design, recycling 12 million per year / year, 5 million per year exempt from sewage charges, the two combined total of 17 million. Two and a half after the substantial return on investment available,[link widoczny dla zalogowanych], resulting in great economic benefits. 6.3 New social HKD drying machine bag filter in the cement plant in Huaibei Mining Group has made good use of effective 2003. N9.4SCIENCEANDTECHNOLOGYOFCEMENT23 fruit, resulting in considerable economic benefits, even greater significance lies in the dryer completely solve the plant in Huaibei city's environmental pollution,[link widoczny dla zalogowanych], its social benefits are immeasurable. 7 transformation Conclusion 1) A HIKE) new bag filter dust as a dryer ventilation system design level is reasonable. Filter design for the whole steel structure,[link widoczny dla zalogowanych], the lower air intake, vacuum operation is also reasonable to meet the production line of the dryer and dust removal process requirements. ''(2) HKD new dryer baghouse adaptable, you can capture different characteristics of the dust, long-term efficient and stable operation,[link widoczny dla zalogowanych], high collection efficiency, especially for fine dust collection efficiency higher export concentration of less than the national iOOmg / m ~ emission standards, the measured results of 50mg / m ~ below, can meet the requirements of continuous use and environmental protection. In addition, if the dust concentration of population in a large range of fluctuation, the emission concentration of dust did not affect exports. (3) Hl <D new bag filter dryer, a \(4) microcomputer automatic control system is reliable. Long-term stable operation, easy to use anti-jamming ability, and easy to achieve \(5) The structural design is reasonable, and is conducive to serialization and on-site assembly, site installation work to reduce and speed up the progress of the project. Dust hopper each pouch has room and access door, replace the bag do not need to check the bag down. (6) dust into the wind and dust exhaust pipes are placed in the interior of the dryer and baghouse other models than the structure more reasonable and compact, taking up less space, low steel consumption reduced equipment investment. (7) with various parameters of the new bag filter, reasonable structure, easy maintenance, operation stable and reliable, and good cleaning effect.
