(1) bag selection: bag house is a use of organic or inorganic fibers filter cloth dust containing gas in solid dust bag filter, inertial impaction, interception, diffusion, electrostatic, gravity sedimentation and other effects isolated under an efficient dust removal equipment, bag is directly related to the efficiency of the dust removal system. Superb sewing techniques and selection of appropriate high-quality filter, high efficiency of the system is the key to protection. Development and development of domestic bag house filter is synchronized, asphalt mixing equipment with dust filter needle felt filter mainly NOMEX aramid needle felt filter and so on. If the asphalt mixing plant using heavy oil, coal or other foreign oil as a fuel, it is necessary to take NOMEX needle felt filter treated in different ways, to suit different requirements, especially with the amount of high sulfur heavy oil, fuel oil as an impurity or higher water content of raw materials, leading to the burning asphalt mixing plant with sticky dust, smoke components and strong acidity. Use of anti-acid, anti-oil and water treatment NOMEX needle felt filter, can greatly improve the wear resistance, high temperature resistance, acid and alkali resistance, hydrolysis resistance and dimensional stability NOMEX filter to improve the clear bag ash dust removal efficiency and performance and service life of the bag. Therefore NOMEX (polyaramide) High temperature needle felt filter is one of the ideal filter dust asphalt concrete equipment, and life can reach more than 2 years. (2) temperature control: general NOMEX bag when subjected to a temperature of 200 ℃, so treatment facilities inlet temperature should be controlled below 200 ℃, reach the cleaner body through the flue gas after the smoke pipe, the temperature can be reduced to 200 ℃ the following. To protect the bag from accidental burning in the bag house flue entrance equipped with a safety valve, with high and low temperature protection device, extended filter bag life. (3) selection of the fan: the use of an adjustable suction mode damper size to adjust the suction device or boiler and burner flame size. (4) According to the filter bag cleaning effect and service life, currently mostly used air filter cleaning or pulse cleaning. (5) Leakage rate: Theoretically calculated baghouse dust removal efficiency of 99%, but measured in reach, mainly the impact of air leakage, the lower the leakage rate, the better the effect of dust. (6) filtration velocity: the lower the average filtration velocity, the larger the filter area, the higher collection efficiency, longer bag life, but the cost will be increased, so according to working conditions, select the appropriate filtration velocity, speed control in general 1 ~ 2m / min, dust effect is better. (7) Container type dust removal system: Before settling chamber is equipped with the cleaner body, the configurations bag filter, formation of secondary dust. Removing a portion of the settling chamber can be large particles of dust, reducing the temperature, the pressure to reduce dust, this part of the large particles of dust as fine aggregate direct reuse; fine dust behind the baghouse collected as powder recycling, both It reached the effect of dust, but also save raw materials. (8) There is also a vacuum dust removal system automatically adjusted to ensure that operating conditions in its best condition, reduce system power consumption. (9) filter bags are generally required to be pre-coating to prevent incomplete combustion burner oil or viscous baghouse dust into direct stick bag paste bag phenomenon occurs. (10) designed the double lever gravity control valve: screw conveyor for ash and dust below the two under a dust by a screw conveyor into the hot aggregate powder hoist or hoist recycling or discharge off valve cover this kind of different weights from the weight of the control valve can automatically switch to ensure that the valve remains closed state, the vacuum dust removal system is not affected by the outside world.
