Abstract
The utility model discloses a kind of electric precipitation storehouse pump bleeder line structure, comprise storehouse pump, pump top, storehouse is connected with ash bucket by pipeline, ash bucket top is provided with electric precipitation body, storehouse pump outer wall is provided with exhaust supervisor, and exhaust supervisor is provided with exhaust main valve, and the exhaust supervisor in exhaust main valve downstream is connected with the other pipe of exhaust, the other pipe of exhaust is provided with the secondary valve of exhaust, and exhaust supervisor inserts on top the connection location of ash bucket and electric precipitation body.The utility model can avoid exhausr port to block, and both can improve safety, ensures that unit is normally with high-load operation, can ensure the tracheae bypass operation that do not begin to rehearse simultaneously, reduce the pollution to surrounding environment; Equipment operation maintenance expense can be decreased again, decrease operating maintenance, repair and maintenance work capacity; In addition, pump each blanking in storehouse can reach full pumping conveying thus save economizes defeated grey compressed air consumption, can subtract the power consumption reducing ash disposal Air compressor.
Description
Technical field
The utility model relates to thermal power generating technology field, is specifically related to a kind of electric precipitation storehouse pump bleeder line structure.
Background technology
In thermal power generating technology field, electric precipitation storehouse pump freeing pipe is generally divided into two-way: a road is freeing pipe bypass, and the air with dust in the pump of storehouse directly enters in air by freeing pipe bypass; Another road is freeing pipe main road, the air with dust in the pump of storehouse is entered electric precipitation body interior, after dedusting, enters flue gas system.Freeing pipe bypass directly enters in air by the air of storehouse pump band dust, because the air got rid of contains a large amount of dust, directly enters air and can cause environmental pollution.Freeing pipe main road is that the air of storehouse pump band dust is entered electric precipitation body interior, environmental pollution can not be caused, but when ash bucket material level increases to over freeing pipe main road exhausr port, freeing pipe main road is blocked, air in the pump of storehouse can not be discharged when storehouse pump blanking, when causing storehouse pump blanking, blanking is smooth, and storehouse pump can not reach full pumping conveying.
Because the coal ash being commonly used to generate electricity is higher, especially in Southwestern China area, the average ash of coal is generally 45%, most Gao Shida 52%, when unit high load capacity (550MW and more than) runs due to defeated grey undercapacity, there will be ash bucket material level to raise, exceed freeing pipe main road exhausr port, cause freeing pipe main road to block, storehouse pump can not be vented, cause storehouse pump can not to fall full pumping, affect the safe operation of unit load carrying and electric field, electric precipitation ash bucket.
Utility model content
The utility model aims to provide a kind of electric precipitation storehouse pump bleeder line structure, to solve in prior art existing defeated grey undercapacity, ash bucket material level raises, the blocking of freeing pipe main road, storehouse pump can not be vented, storehouse pump can not fall full pumping problem.
The utility model is achieved by following technical solution:
A kind of electric precipitation storehouse pump bleeder line structure, comprise storehouse pump, pump top, storehouse is connected with ash bucket by pipeline, ash bucket top is provided with electric precipitation body, storehouse pump outer wall is provided with exhaust supervisor, and exhaust supervisor is provided with exhaust main valve, and the exhaust supervisor in exhaust main valve downstream is connected with the other pipe of exhaust, the other pipe of exhaust is provided with the secondary valve of exhaust, and the connection location of ash bucket and electric precipitation body is inserted on described exhaust supervisor top.
The beneficial effects of the utility model are:
Compared with prior art, the electric precipitation storehouse pump bleeder line structure that the utility model provides, exhaust supervisor exhausr port will move to the connection location of ash bucket and electric precipitation body, avoids ash bucket material level to raise the exhausr port blocking of exhaust supervisor, affect storehouse pump exhaust.Both can improve the safe reliability of electric field, electric precipitation ash bucket, ensure that unit was normally with high-load operation, and the tracheae bypass operation that do not begin to rehearse can have been ensured simultaneously, reduce the pollution to surrounding environment; Equipment operation maintenance expense can be decreased again, decrease operating maintenance, repair and maintenance work capacity; In addition, pump each blanking in storehouse can reach full pumping conveying thus save economizes defeated grey compressed air consumption, can subtract the power consumption reducing ash disposal Air compressor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the pump of 1-storehouse, 2-ash bucket, 3-electric precipitation body, 4-is vented supervisor, and the other pipe of 5-exhaust, 6-is vented main valve, and 7-is vented secondary valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1, the electric precipitation storehouse pump bleeder line structure that the utility model provides, comprise storehouse pump 1, storehouse pump 1 top is connected with ash bucket 2 by pipeline, and ash bucket 2 top is provided with electric precipitation body 3, and storehouse pump 1 outer wall is provided with exhaust supervisor 4, exhaust supervisor 4 is provided with exhaust main valve 6, the exhaust supervisor 4 in exhaust main valve 6 downstream is connected with the other pipe 5 of exhaust, and be vented on other pipe 5 and be provided with the secondary valve 7 of exhaust, the connection location of ash bucket 2 and electric precipitation body 3 is inserted on described exhaust supervisor 4 top.Open exhaust main valve 6, close the secondary valve 7 of exhaust, in storehouse pump 1, the air of band dust enters the connection location of ash bucket 2 and electric precipitation body 3 by exhaust supervisor 4, air with dust enters in electric precipitation body 3 and carries out dedusting, air after dedusting just can enter in air, and the exhausr port end of exhaust supervisor 4 is arranged on the connection location of ash bucket 2 and electric precipitation body 3 due to the utility model, fall in ash bucket 2 ash time, the dust be deposited in ash bucket 2 can not block the exhausr port of exhaust supervisor 4, both electric field can be improved, the safe reliability of electric precipitation ash bucket, ensure that unit is normally with high-load operation, the tracheae bypass operation that do not begin to rehearse can be ensured simultaneously, reduce the pollution to surrounding environment, equipment operation maintenance expense can be decreased again, decrease operating maintenance, repair and maintenance work capacity, in addition, pump each blanking in storehouse can reach full pumping conveying thus save economizes defeated grey compressed air consumption, can subtract the power consumption reducing ash disposal Air compressor.
