Description
Technical field
The utility model relates to bag filters, more particularly, to the filter bag ash removal device of bag filter.
Background technique
The filter bag of bag filter is in dust removal process, as the dust for being attached to filter bag surface increases, filtered airflow
Channel can be gradually reduced, and cause filter bag to increase the resistance of air-flow, can if things go on like this seriously affect the dust removing effects of filter bag.Cause
This, in order to guarantee that dust removing effects, bag filter require to clear up attachment in time by filter bag ash removal device in use
In the dust of filter bag surface.
Currently, filter bag ash removal device mostly uses pulse dust cleaning mode, pulsed filter bag ash removal device mainly include pulse valve,
Gas bag and injection tube, one end of injection tube pass through gas bag and are connected to pulse valve, and the other end protrudes into filter bag area.When clearing up filter bag,
Pulse valve is opened, reverse impulse air-flow rises the pressure in filter bag rapidly, and filter bag expands rapidly outward, makes to be attached to filter bag table
The dust in face is shaken off.Since air pulse is contrary with the filtered airflow of bag filter, need when clearing up filter bag by cloth bag
The power source of deduster is closed, and influences normal filtration operation, and pulsed filter bag ash removal apparatus structure is complicated, cost is high.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem, to provide a kind of filter bag ash removal dress for bag filter
It sets, in filter bag ash removal, without closing bag filter power source, guarantees that filtration operation works normally, structure is simple, cost
It is low.
The technical solution of the utility model is:
A kind of filter bag ash removal device for bag filter, including dust cleaning case, the dust cleaning case are separated by partition
The exhaust chamber in portion, the filter chamber of lower front side, lower rearward side exhaust duct arranged up and down and flue, filtering indoor top setting
Filter bag, the partition between filter chamber and flue are equipped with smoke intaking hole, and the partition between exhaust chamber and exhaust duct is equipped with exhaust outlet,
It is characterized in that the exhaust chamber is separated into the exhaust locellus that multiple left and right are arranged side by side by partition, outside each exhaust locellus
Lift cylinders are inverted in top surface, and the corresponding exhaust locellus of lift cylinders cylinder rod insertion, each lift cylinders cylinder rod bottom end is installed and corresponding exhaust outlet
The cover board of face, and be located at lift cylinders in each exhaust locellus inner top surface and be surrounded by air inlet.
Further preferably, the exhaust flange coaxial with exhaust outlet is equipped in each exhaust locellus inner bottom surface.
Further preferably, each exhaust locellus inner top surface be equipped with by air inlet be trapped among in it and with lift cylinders it is coaxial into
Gas flange.
Further preferably, it is covered with ventilation rain cover in each lift cylinders, guarantees that natural air can enter ventilation rain cover
Under the premise of interior, lift cylinders moisture damage is prevented.
The beneficial effects of the utility model are:
Due to outside multiple exhaust locellus top surface be inverted lift cylinders, each lift cylinders cylinder rod bottom end installation with corresponding exhaust outlet just
Pair cover board, and be located at lift cylinders in each exhaust locellus inner top surface and be surrounded by air inlet, when filter operation, above propose lift cylinders
Cylinder rod closes cover board by air inlet, and filtered clean gas is successively discharged into atmosphere through exhaust chamber, exhaust duct；Cleaning filter
When bag operation, lift cylinders cylinder rod in each exhaust chamber is successively fallen from left to right, makes the cover closure pair of lift cylinders cylinder rod bottom end
The exhaust outlet answered, each lift cylinders circuit sequentially cleaning filter bag operation；When lift cylinders cylinder rod falls, the lid of lift cylinders cylinder rod bottom end
Plate recline corresponding exhaust outlet when, outside air enters in corresponding filter bag through air inlet, exhaust chamber, cuts down corresponding sock filtration
Air pressure makes its expansion, to the dust being attached on the filter bag be shaken off to filter chamber bottom, when clearing up filter bag, without closing
Bag filter power source ensure that filtration operation works normally, and structure is simple, low cost.
