The dust cleaning system of GA type air cleaning bag filter with high frequency vibration and anti air handling, which blow back by a specially designed electric cylinder to drive the valve to achieve the electric cylinder action is controlled by a set of automatic control system, ratio of pulse back blowing and high pressure blow back bag dust collector used in the past. Save the auxiliary equipment investment, but also significantly reduce the operating costs of electricity consumption and equipment.
Work with the time extension, the bag on the inner wall of the dust layer thickness increases, the resistance is gradually rising high value reached 80 ~ 120 mm horizontal column, we can pass through the U type pressure gauge to see this change, the electric cylinder start the main valve plate using electric three-way valve closed, the valve plate can be opened to pay. For cleaning. At the same time, the device also has the advantages of stable and reliable performance, long service life of the filter bag, high efficiency, convenient maintenance etc.. The intake pipe into the hopper dust containing gas, and then to the box body through the bag after the purification, the main valve plate opening by electric three-way valve row to the trachea, tracheal gas by centrifugal fan, chimney into the atmosphere. The dust collector is widely used in ceramics, metallurgy, casting, light industry, food, building materials, chemical industry and so on.
The main features of GA type air cleaning bag filter:
GA type air bag type dust collector by import and export, flue dust chamber, air purifying chamber, cleaning system and bucket etc.. The off-line pulse filter when the exhaust gas temperature is reduced to 130 DEG C, up to the moment distribution of inlet flue gas containing dust by 180 DEG C in the lower part of the bag filter after entering the room the ash bucket, baffle and speed reducing flue gas due to such causes as dust particles are thick and heavy in the settlement, reached the pre separation the purpose of. Fine dust with air turning to dust chamber into the off-line pulse filter, the filtering effect of off line pulse dust bag, dust by the outer surface resistance in the bag, net gas filtered pulse air purifying chamber filter bag dust collector into each unit by off-line, and converge to the outlet flue through the draft "the fan through the chimney into the atmosphere.
In the GA series of air cleaning daily operation of ash bag filter, because the operating conditions will have some changes, or some faults occur, the normal operation and performance will affect the equipment, to regularly check and adjust the appropriate, the purpose is to extend the life of the filter dust, reduce power consumption and recycling useful materials.
GA series air cleaning dust bag filter should pay special attention to the measures taken to prevent combustion, explosion and fire accident. In the high temperature gas or gas combustion process, there is often dust, incomplete combustion of Mars, burning and explosive gas into the system, some dust has auto ignition properties or charged, at the same time, most of the material is easy to filter and burning, friction is easy to produce static electricity accumulation, in this operation under the condition of occurring explosion combustion accident, and the accident consequences are often very serious. Should be well considered to take fire, explosion-proof measures, such as:
In a combustion chamber or Mars trap in front of dust collector, so that the dust and gas incomplete combustion combustion or the Mars capture down.
We take measures to prevent the accumulation of static electricity, the conductive material for grounding, or conductive fiber in the filter manufacturing.
To prevent dust accumulation or dust accumulation, so as to avoid spontaneous combustion and explosion.
Check or repair the people into the bag chamber or pipe, be sure to ventilation, to prevent CO poisoning
