Summary of the invention
The purpose of this utility model is exactly in order to solve the above-mentioned defective of prior art, and provide a kind of raising deduster reliability of operation, improve the deduster dust removing effects, be particularly suitable for electric cleaner and transform sack cleaner as, the end inlet side that has enlarged the scope of application of sack cleaner goes out the multicell Low-Pressure Pulse Bag Filter.
The purpose of this utility model realizes by following technical solution:
A kind of Low-Pressure Pulse Bag Filter, comprise upper box, middle casing, import smoke box, outlet smoke box, lower box, each casing is communicated with in the space, is provided with filter bag in the middle casing, is provided with gas bag in the upper box, be provided with ash bucket in the lower box, wherein said one deck airflow-distribution board that is provided with at least in the import smoke box is provided with a plurality of filter chambers in middle casing, the passage of boiler smoke goes out for the end inlet side, the direction that boiler smoke enters the import smoke box is consistent with the direction of leaving the outlet smoke box, is straight direction.
The purpose of this utility model also can further realize by following technology solution:
Airflow-distribution board is provided with in the face of the air current flow direction and with the air current flow direction is vertical for positive in the aforesaid a kind of Low-Pressure Pulse Bag Filter, wherein said import smoke box, and airflow-distribution board is provided with airflow hole.
Aforesaid a kind of Low-Pressure Pulse Bag Filter, the wherein said blind plate district that on airflow-distribution board, is positioned at center position that air communication crosses for not perforate.
Aforesaid a kind of Low-Pressure Pulse Bag Filter, wherein said in the import smoke box along airflow direction in the back of airflow-distribution board the parallel airflow uniform distribution plate that is provided with, evenly open air-flow distribution hole on the described airflow uniform distribution plate.
Aforementioned a kind of Low-Pressure Pulse Bag Filter, wherein said in upper box the adjacent of each filter chamber be linked with spoiler vertically downward, the height of each spoiler successively decreases in regular turn according to airflow direction, the line of each spoiler 13 forms a wedge shape discharge pipe.
This practical advantage is: air current composition and air intake mode be through simulated test, thereby simple in structure, and air current composition is reasonable, and the deduster running resistance is low, and be reliable, efficiency of dust collection is high; Pulse dust cleaning is effective, damages little to filter bag; Can create bigger economic benefit, thereby be widely applied to the dedusting field of industries such as electric power, iron and steel, cement.
The purpose of this utility model, advantage and characteristics will illustrate and explain that these embodiment only provide as an example with reference to accompanying drawing by the non-sex-limited explanation of following preferential embodiment.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is the utility model airflow-distribution board structural representation.
The specific embodiment
As shown in Figure 1-Figure 3, the utility model comprises upper box 5, middle casing 2, import smoke box 3, outlet smoke box 4, lower box 14, described each casing is communicated with in the space, be provided with filter bag filter bag and framework 6 in the middle casing 2, be provided with gas bag 7 in the upper box 5, be provided with several ash buckets 1 in the lower box 14, in import smoke box 3, be provided with one deck airflow-distribution board 11 at least, can be multilayer; Main design parameters is installation site, percent opening and position of opening; Airflow-distribution board 11 is provided with in the face of the air current flow direction and with the air current flow direction is vertical for positive, and airflow-distribution board 11 is provided with airflow hole 15, and the airflow hole that described this air-flow distributes adopts circular hole, and diameter is determined according to importing and exporting size, is generally about 45mm; In order to reduce the influence of central gas stream, on airflow-distribution board 11, be positioned at import center position that air communication crosses blind plate district 19 for not perforate for airflow homogeneity; In import smoke box 3 along airflow direction in the back of airflow-distribution board 11 the parallel airflow uniform distribution plate 12 that is provided with, evenly open air-flow distribution hole on the described airflow uniform distribution plate 12, the percent opening in air-flow distribution hole and installation site will be determined according to inlet size and shape and exhaust gas volumn.Be provided with a plurality of filter chambers 20 in middle casing 2, each filter chamber 20 is corresponding with ash bucket respectively; The passage of boiler smoke goes out for the end inlet side, and the direction that boiler smoke enters import smoke box 3 is consistent with the direction of leaving outlet smoke box 4, is straight direction.The adjacent of each filter chamber 20 is linked with spoiler 13 vertically downward in upper box 5, the height of each spoiler 13 successively decreases in regular turn according to airflow direction, the line of described each spoiler is provided with in upper box 5 and forms a wedge shape discharge pipe, and main design parameters is the spoiler height.
The utility model is when work, and the straight deduster that enters of boiler smoke in the described flue is end and advances; Air-flow adopts direct-passing mode, and in regular turn by several layers airflow-distribution board 11 and air-flow uniform board 12 are set in the import smoke box 3, because airflow-distribution board 11 is provided with the not perforate blind plate of certain area in the heart in aiming at import, can avoid the excessive difficulty that causes airflow uniform distribution to be adjusted of center flow velocity, and two plates are evenly opened circular hole, percent opening and installation site are all determined according to inlet size and shape and exhaust gas volumn, cause air-flow through out-of-date, but the even regulation air velocity is unanimous between the higher and lower levels, make air-flow even, resistance is little, reduces resistance and decreases, and increases the service life of filter bag.Air-flow enters upper box 5 again, because the line of each spoiler 13 forms a wedge shape discharge pipe in the upper box 5, it successively decreases highly in regular turn, makes each chamber actual treatment exhaust gas volumn even; Injection system comprises gas bag 7, pulse valve 8, jet pipe 9 and nozzle 10, adopt the low-pressure compressed air of 0.25-0.35Mpa owing to process gas bag 7, pulse valve 8, jet pipe 9 and nozzle 10 at middle casing 2 air-flows, filter-bag blowing line by line, the dust of filter bag is trembled in the ash bucket 1, air current composition flows out by outlet smoke box 4, promptly brings out and by the flue machine of giving a dinner for a visitor from afar; Whole dust removal process finishes.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
