Abstract
The utility model relates to a bag dust remover used for removing dust and smoke, with adopting an inner filter downstream mode, the filter cloth is arranged as a flat bag shape. The dust remover can be operated in a negative pressure state, the collected dust on the bag can be removed with adopting an air leakage dust cleaning mode, and the filter cloth can continuously process the dusty air.
Description
This deduster is in environmental engineering and the Labor Protection, is used for eliminating the novel sack cleaner of the dust of air-flow.
Sack cleaner is of a great variety; the domestic representative pulse bag type dust collector (national general building standard design atlas CT536) that has; the double-deck sack cleaner of LFS type blowback wind (is won Beijing's scientific and technological achievement third prize; the Beijing City Inst. of Labour Safety Science is designed), the horizontal flat bag reversed bay-type deduster of HBF type (Wuhan Iron and Steel Company planning and design institute, Xiangxiang Machinery Factory, Hunan Prov.'s development) etc.These dedusters are all openly produced and sample are arranged.
With filter cloth dust laden air is filtered, have the high advantage of efficiency of dust collection.Therefore, bag-type dust is a kind of important means that purifies air, and its application is very widely.
(mainly refer to efficiency of dust collection, resistance, processing air quantity, filter cloth material and filter area etc.) under the same conditions, the volume minimum of which kind of sack cleaner, minimum with material, to make easily, cost is minimum, and simple and convenient management and power consumption power consumption are minimum, and it is just advanced relatively.But, accomplish comprehensively that these are not easy.
The cloth bag of pulse bag type dust collector is a cylindrical shape, and it can not be littler than flat bag filter volume, and it also uses the compressed air deashing, thereby just poor on the ease of use, and it is also big to consume energy.
The double-deck sack cleaner of LFS type blowback wind, its volume is littler than the former, and is few compared with making things convenient for and consume energy with the compressed air blowback with the blower fan reverse gas cleaning.
The horizontal flat bag reversed bay-type deduster of HBF type, be to design on the basis of the sack cleaner advantage that has absorbed domestic and international production, its advantage was in the majority, on September 20th, 1984, be tested and appraised by twenty several units such as Institute of Safety Technology, Ministry of Metallurgical Induatry, the great achievement of the deduster of this deduster collection China and known external production, advantage are a lot, but undesirable part is also arranged, as sub-room cleaning, just can not work during the cloth bag deashing, be sub-room cleaning, deduster just does complicatedly.
The utility model---the purpose of design of downflow type flat bag filter attempts sack cleaner should be had, but usually the advantage of contradiction is unified in one, thereby produces comparatively desirable sack cleaner.
Under request in person and see downflow type flat bag filter schematic diagram (Fig. 1):
Dust-contained airflow is entered in the upper box (2) by blast pipe (1), is distributed to then in each cloth bag (3).Through the cloth bag filtration, the cleaned air that concentrates in the middle casing (4) is discharged by exhaust duct (5), and this is whole purification process.
In the cloth bag, the big dust particle in the dust-contained airflow will be deposited to bottom ash bucket (10) because of deadweight.The granule dust can be with air-flow attached on the cloth bag inwall.Cloth bag and the equal filtration of dust of adhering on it.This layer adheres to grieshoch and claims dust filtering layer, dust filtering layer, and we do not wish that it is too thin, do not wish that it is too thick yet.Too thin, efficiency of dust collection is just low.Too thick, resistance is big, and the blower fan load is big.The cloth bag deashing is considered this point especially.
Airflow direction is consistent with ash fall direction (downwards), and this claims following current.Following current can impel big dust particle to settle down rapidly.Following current can impel dust filtering layer to cave in when reaching certain thickness down, and following current can not make the dust that has settled down be attached on the cloth bag once more.Also have, because of being following current, the deashing process of cloth bag and filter process can carry out simultaneously.Therefore, following current meets dust removal mechanism most.
Cloth bag section of the present utility model is flat-shaped, so can arrange more filter cloth in the middle casing of certain space, please see downflow type flat bag filter structure diagram (Fig. 2) and 1-1 profile (Fig. 3).
For making cloth bag be flat-shaped, cloth bag is placed in the cloth-bag frame (6), during the cloth bag inflation, can become flat bag because of Frame's Constrain.Frame fixation is in middle casing, and it is to be made by the graticule mesh of wire netting or other material and necessary skeleton.
The two ends of cloth bag are fixed on up and down on the short tube (7) (8).Install or the replacing cloth bag, need not move cloth-bag frame.This just makes operation become quite easy.
Deashing adopts the deashing method of leaking out.Please see Figure 1, deduster moves under negative pressure state, and when its resistance surpassed setting, control pressurer system will be opened the deashing tube valve in order.Deashing pipe (9) is general steel pipe, has aperture in the horizontal direction, and the end port in deduster is shut, and the end in the deduster outside is equipped with valve.Valve one is opened, and air-flow will fling cloth bag from aperture, and this wind can play the deashing effect completely, and is minimum because of leaking out, so can not influence the processing air quantity of deduster.
Can be according to the multiple model that how much is designed to of handling air quantity.Ash bucket (10) and ash exhauster (11) are conventional design, and filter cloth is to supply on the market.
The utility model mainly contains following different with the horizontal flat bag reversed bay-type deduster of HBF type:
1, filter following current in the utility model adopts, the latter adopts outer filter following current.Interior filter following current is more outstanding than outer filter following current advantage.
2, the former locellus not, the cloth bag continuous operation.Latter's locellus, the work of cloth bag interruption.Therefore, the former volume is littler.
3, the former adopts the deashing method of leaking out, and deduster is simple in structure.Latter's sub-room cleaning, complex structure.
Claims (2)
1, in environmental protection and the labour protection engineering, is used for eliminating a kind of flat bag filter of the dust in the air-flow.The top of this deduster is blast pipe (1) and upper box (2), and the middle part is middle casing (4) and exhaust duct (5), and the bottom is ash bucket (10) and ash exhauster (11).In the middle casing (4) is cloth bag (3), cloth-bag frame (6) and deashing pipe (9).It is characterized in that:
A, cloth bag (3) vertical hanging arrange that it is both ends open up and down.Cloth bag upper end open and upper box (2) communicate.Cloth bag lower ending opening and ash bucket (10) communicate.
B, cloth bag (3) place in the cloth-bag frame (6).Cloth-bag frame (6) is fixed in the middle casing (4).
