Description
Technical field
The present invention relates to the technical field of cleaner structural design, particularly relate to a kind of sack cleaner.
Background technology
Sack cleaner is a kind of dry type dust filtration device, and it is applicable to trap tiny, dry, non-fiber dust.The filter bag of existing sack cleaner adopts the filter cloth of weaving or nonwoven felt to become, the filtration of fabric is utilized to filter dusty gas, after dusty gas enters sack cleaner, large, the heavy dust of particle, because the effect of gravity settles down, fall into ash bucket, containing the gas compared with fine dusts when by filter bag, dust, by detention, makes gas be purified.
The applicant finds that existing sack cleaner exists following problem:
The intake of each bin 1, in sack cleaner is unequal, and the load that each filter bag bears is uneven, and cause part filter bag load excessive, the life-span has a greatly reduced quality.Simultaneously also cause the storage ash quantity in each ash bucket unequal, easily cause equipment centre-of gravity shift, the accident such as to decay.Also easily make the load of downstream ash material conveying equipment uneven.And there is the defeated ash of the excessive bin of load not in time, also easily block, block clearing need be shut down, the normal operation of influential system.
2. dusty gas enters each bin by ash bucket.Because the initial flow rate of dusty gas is fast, cause filter bag undermining phenomenon serious.And due to gas flow be from the bottom to top, the dust under filter bag is cleared up presents suspended state under the effect of updraft, is repeatedly adsorbed on filter bag and is difficult to fall into ash bucket, cause equipment resistance to rise, energy consumption strengthen.And force soot cleaning system (soot cleaning system work can cause adverse effect to life-span of the filter bag) high-frequency operation, cause life-span of the filter bag to reduce.
3. rounded pocket takies equipment sectional area greatly, and is unfavorable for the gas flowing between filter bag.Can not ensure the filter bag uniform load of same bin in running, the filter bag premature aging causing load too high damages.And low load zones often produces low temperature because air-flow is few, final dewing corrosion.
Therefore, the applicant is devoted to develop a kind of sack cleaner effectively can eliminating at least one the problems referred to above, improves service life and the dedusting effect of equipment.
Summary of the invention
Object of the present invention, propose one exactly and can realize each bin uniform air intake in running, uniform load, service life of equipment is longer, the sack cleaner of better dust removal effect.
The present invention is for solving the problems of the technologies described above, provide a kind of sack cleaner, comprise frame, dedusting bin, intake stack and wind pipe, described dedusting bin is arranged in described frame, described intake stack and the conducting respectively of described wind pipe are arranged on described dedusting bin, dusty gas to enter in described dedusting bin after filter dust by described intake stack, is externally exported by described wind pipe.
Wherein, multiple described dedusting bin respectively conducting is connected on described intake stack, described intake stack is formed with multiple connector, described in each, connector correspondence connects a described dedusting bin, and connector described in each is provided with one for realizing the air distribution valve of the allocation of the amount of airs such as each dedusting bin.
The present invention enough realizes dusty gas by above technical scheme and carries out allocation of the amount of air such as grade by intake stack, and import each dedusting cabin indoor respectively and process, in running, each bin air intake is even, uniform load, thus effective raising service life of equipment is longer and dust removing effects.
Preferably, dedusting bin of the present invention comprises warehouse, air inlet, deflector, filter bag and ash bucket, described ash bucket conducting is docked at the bottom of described warehouse, described deflector is vertically plugged in described warehouse, described warehouse is divided into water conservancy diversion decanting zone and filter bag district, described water conservancy diversion decanting zone and described filter bag district are in the upper position mutual conduction of described warehouse, multiple described filter bag is all mounted in described filter bag district, described air inlet is opened on the lower position of described water conservancy diversion decanting zone of described warehouse, for docking with described connector, described dusty gas is imported by the lower position of the described water conservancy diversion decanting zone of described warehouse, described dusty gas enters described water conservancy diversion decanting zone flow velocity and declines, most of dust is caused directly to fall into described ash bucket, all the other dust are guided into the top of described water conservancy diversion decanting zone by described deflector with low speed flow, enter described filter bag district, again filtered by described filter bag.
The present invention is by further improvement to described dedusting bin, and make described dusty gas be subject to the effect of deflector when just entering described dedusting bin, its flow velocity declines to a great extent, and causes most of dust directly to fall into ash bucket in water conservancy diversion decanting zone with regard to sedimentation.By the difference of deflector top and bottom openings of sizes, air-flow is greater than by upper end flow resistance by the flow resistance of lower end, thus regulates the flow direction of air-flow in water conservancy diversion decanting zone, airflow direction is flowed to deflector upper end by deflector lower end.All the other dust then guide top, filter bag room with low speed flow into by described deflector, and air-flow slowly and evenly diffuses to whole filter bag room from top to bottom.The present invention, under the protection of described deflector, reduces dusty gas washing away filter bag, extends life of bag filter, and can reduce flow velocity reduction resistance.
Preferably, described filter bag adopts cross section to be oval elliptical filter bag, multiple described filter bag is being arranged in described filter bag district of many row arrays column alignment, and the long axis direction of the oval cross section of filter bag described in each and the airflow direction of dusty gas are arranged in parallel.
The present invention is by structure of filter bag design as above and layout, make to enter filter bag room by the air-flow of deflector along the long axis direction of elliptical filter bag, give full play to the feature that front face area reduces, increase liquid flowability between filter bag, gas is enable to flow to the every nook and cranny of filter bag room uniformly, make the load of every bar filter bag equal, higher than dew-point temperature, avoid dewing corrosion by temperature in good gas flowing guard box body.
Preferably, described intake stack comprises the connecting pipe of the bores such as a main pipeline and N root, N be greater than 1 integer, whole described connecting pipe is all docked on described main pipeline, and described intake stack forms a described connector by connecting pipe described in each.
Preferably, the cross section of described main pipeline is square, and the cross section of described connecting pipe is also square, and connecting pipe described in each is all equal with the interface of described main pipeline, and the area sum of whole described interface equals the cross-sectional area of described main pipeline.
The present invention, by intake stack structural design as above and layout, further realizes, to the allocation of the amount of air such as grade of dusty gas, playing a multiplier effect.
Preferably, described dedusting bin also comprises soot cleaning system, and described soot cleaning system is arranged on described warehouse, is connected with described filter bag, for removing dust stratification on described filter bag.
Preferably, described dedusting bin also comprises clean air fluidized bed, described clean air fluidized bed is arranged on described warehouse top, after described dusty gas is filtered by described dedusting bin, all import described clean air fluidized bed, be connected to described wind pipe by the conducting of described clean air fluidized bed and externally discharge.
Preferably, the quantity of described dedusting bin is 6, is evenly arranged in described frame between two side by side.
