At present the dedusting method of such gas is divided into to wet method and dry method dust.Wet dedusting not only expends great lot of water resources, also produces a large amount of secondarily polluted waters, and the heat energy loss of waste heat gas is large, is difficult to realize heat recovery.Existing dry method dust purification techniques is of a great variety, comprise gravitational dust collection, inertial dust collection, electric precipitation, bag-type dust, cyclonic separation etc., these equipment ubiquity complex structures are huge, technological requirement is harsh, dust stratification is difficult to cleaning, manufacturing cost and the defects such as the working service cost is high, narrow application range.For the heat recovery of the cryogenic gas that contains a large amount of dust, should consider dedusting, take again the low-loss of heat energy into account, also to consider to reduce secondary pollution, simple in structure, easy and simple to handle, the factor such as cost is low, take into account energy-conservation, economy, environmental protection.To this, prior art does not also have solution preferably.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the utility model provides a kind of low temperature exhaust heat gas automatic dust removing apparatus, and this apparatus structure is simple, and cost is low, and the gas waste-heat loss is little, can fast automatic cleaning collect dust stratification, and easy to use, secondary pollution is little.
the technical scheme that the utility model technical solution problem adopts is: a kind of low temperature exhaust heat gas automatic dust removing apparatus, comprise tubular shell, axle, cylindrical filter frame, filter felt, mouth spray, air inlet, normally closed sewage draining exit, exhausting stub tube, escape pipe, air-introduced machine, pressure sensor and Automatic clearance control system, air inlet is located at tubular shell side top, normally closed sewage draining exit is located at the tubular shell below, mouth spray is distributed in the tubular shell inwall, pressure sensor is located in tubular shell, cylindrical filter frame is positioned in the middle of the tubular shell inner chamber, for the frame hollow structure, on external cylindrical surface, with some reinforcing bars, connect both ends of the surface, its lower surface sealing also is connected with axle, axle stretches out from the tubular shell below by sealing ring and bearing, its upper surface connects exhausting stub tube, exhausting stub tube stretches out from the tubular shell top by sealing ring and bearing, the outer cover escape pipe, air-introduced machine is located at the escape pipe place, filter felt is coated and fixed on cylindrical filter frame external cylindrical surface.During work, need the gas of dedusting to enter from air inlet, under the air-introduced machine effect, after the felt dust removal by filtration, entering cylindrical filter frame inner chamber after filtration, then discharge through the exhausting stub tube of cylindrical filter frame upper surface, enter escape pipe, thereby obtain the gas after udst separation.When the dust accumulation on filter felt is saturated; in tubular shell, gas pressure increases; pressure sensor drives the Automatic clearance control system and under stopped status, is not controlling mouth spray, axle, normally closed sewage draining exit successive relay trip; a plurality of mouth spray water spray flush clean filter felts on the tubular shell inwall; axle drives cylindrical filter frame rotation and dries filter felt, and sewage is discharged from the normally closed sewage draining exit of tubular shell below.Thereby realize automatic dust removing, Automatic clearance collection dust stratification.
As preferably, filter felt is the filter felt of polyphenylene sulfide fibre material.The polyphenylene sulfide fibre filter felt has good temperature tolerance, corrosion resistance, anti-flammability and strainability, and its fusing point is 285 ℃, and continuously serviceability temperature is 170 ℃, moment 190 ℃ of serviceability temperatures, can adapt to well the dedusting needs of low temperature exhaust heat gas.
As preferably, the inner bottom surface of tubular shell is slope shape.So that the sewage that produces while cleaning collects discharge to normally closed sewage draining exit.
The beneficial effects of the utility model are, simple in structure, cost is low, and the gas waste-heat loss is little, easy to use, and automaticity is high, can collect dust stratification in fast automatic cleaning under stopped status not, and secondary pollution is little, and energy consumption is low.
