Abstract
The utility model provides a short-process blowing dust cleaning device. The length of a blowing tube is reduced, so that the length of blown air flow is ensured, the energy consumption for compressing air is reduced, the dust cleaning effect of a filtering bag is good, and the filtering bag can be lengthened. The device comprises air bags, pulse valves, blowing tubes, filtering bags and an air bag inlet tube, wherein the outlet of the air bag inlet tube is communicated with an air inlet in one end of each air bag; a compressed air source is connected with the inlet of the air bag inlet tube. The device is characterized in that air bag outlets are distributed on the air bags and are respectively connected with the air inlet of the corresponding pulse valve; the air outlets of the pulse valves are connected with the upper openings of the corresponding blowing tubes; the blowing tubes are vertically arranged; the lower openings of the blowing tubes face to the upper openings of the corresponding filtering bags; the filtering bags are positioned just below the corresponding blowing tubes and are only provided with the upper openings.
Description
Technical field
The utility model relates to the dedusting technology field of energy-conserving and environment-protective industry, is specially a kind of short flow process jetting deashing device.
Background technology
Existing pulse bag type dust collector mostly adopts tubular type jetting deashing device, mainly gas bag, pulse valve, injection tube, several nozzle, filter bag etc., consists of.The positional distance filter bag of gas bag is distant, when filter bag needs deashing, opens pulse valve, and the compressed air in gas bag enters injection tube, then by a plurality of left and right of tube wall side nozzle, sprays simultaneously, is ejected into respectively in corresponding filter bag.Due to compressed air high velocity stream, cross long and with the injection tube of bend pipe, resistance is damaged quite large, compressed air energy consumption is higher; And compressed air successively enters into each nozzle of diverse location by jet pipe, make each nozzle spray compressed-air actuated pressure, mass flow discrepancy weighing apparatus, outgassing direction and nozzle shaft, to there being some to depart from, have shortened the length of jet-stream wind, affect filter bag ash removal effect, filter bag length is restricted.
Summary of the invention
For existing above-mentioned defect, the utility model provides a kind of short flow process jetting deashing device, and the length of its injection tube reduces, and guarantees the length of jet-stream wind, makes that compressed air energy consumption is low, filter bag ash removal is effective, and filter bag can lengthen.
A kind of short flow process jetting deashing device, its technical scheme is such: it comprises gas bag, pulse valve, injection tube, filter bag, gas bag air inlet pipe, the outlet of described gas bag air inlet pipe is communicated with one end air inlet of described gas bag, compressed air gas source connects the import of described gas bag air inlet pipe, it is characterized in that: on described gas bag, be placed with gas bag gas outlet, described gas bag gas outlet connects respectively the air inlet of corresponding described pulse valve, the gas outlet of described pulse valve connects the upper port of corresponding described injection tube, described injection tube is arranged vertically, the lower port of described injection tube is towards the upper opening of the described filter bag of correspondence, described filter bag be positioned at corresponding described injection tube under position, described filter bag only arranges upper opening.
It is further characterized in that: the length of described filter bag is 7 meters～10 meters;
Described pulse valve is specially submerging pulse valve, described gas bag gas outlet is positioned at the top of described gas bag, the valve seat of described submerging pulse valve is flush-mounted in described gas bag gas outlet, it is inner that the gas outlet of described submerging pulse valve is positioned at described gas bag, and the gas outlet that is communicated with described submerging pulse valve after the lower sides of described gas bag is run through on the top of injection tube.
Adopt after the utility model, by gas bag, pulse valve is arranged on the top of upper opening of the filter bag of pulse bag type dust collector inside, injection tube is arranged vertically, upper port is communicated with pulse valve, lower port is directly aimed at the upper opening of filter bag filter bag, can make injection tube length greatly reduce, compressed air flow process only has the distance of 300mm～500mm from pulse valve to injection tube lower port, injection tube resistance is damaged obviously and is declined, can reduce compressed-air actuated pressure simultaneously, reduce compressed-air actuated energy consumption, and an injection tube is only to a filter-bag blowing deashing, the air-flow of each injection tube ejection does not interfere with each other, make the stream pressure of each injection tube ejection, flow-rate ratio is more balanced, improved the ash-removal effect of deduster.Injection tube compressed air flows to consistent vertically downward with the airflow direction of ejection, has increased the length of jet-stream wind, can increase the length of filter bag, also can improve filter bag ash removal effect simultaneously; The increase of filter bag length can reduce the floor space of deduster, save the material of deduster, can also be near dirt source flexible arrangement deduster, reduced the adapter between deduster and dirt source, save the material of pipeline, reduced the power consumption of dust pelletizing system, saved investment and operating cost, improve economic benefit and social benefit, be widely used in the industry-by-industries such as building materials, metallurgy, chemical industry, the energy.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model;
Fig. 2 is the left view structural representation of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2, it comprises gas bag 1, pulse valve 2, injection tube 3, filter bag 4, gas bag air inlet pipe 5, the outlet of gas bag air inlet 5 is communicated with one end air inlet of gas bag 1, compressed air gas source connects the import of gas bag air inlet pipe 5, on gas bag 1, be placed with gas bag gas outlet 6, gas bag gas outlet 6 connects respectively the air inlet of corresponding pulse valve 2, the gas outlet 7 of pulse valve 2 connects the upper port of corresponding injection tube 3, injection tube 3 is arranged vertically, the lower port of injection tube 3 is towards the upper opening of corresponding filter bag 4, it is the upper opening that the lower port of injection tube 3 is directly aimed at filter bag 4, filter bag 4 be positioned at corresponding injection tube 3 under position, filter bag 4 only arranges upper opening.
Wherein, the length L of filter bag is 7 meters～10 meters, pulse valve 2 is specially submerging pulse valve, gas bag gas outlet 6 is positioned at the top of gas bag 1, the valve seat of submerging pulse valve is flush-mounted in gas bag gas outlet 6, the gas outlet 7 of submerging pulse valve is positioned at gas bag 1 inside, and the gas outlet 7 that is communicated with submerging pulse valve after the lower sides of gas bag 1 is run through on the top of injection tube 3.
In figure, arrow is gas flow direction.
Its operation principle is as follows: blowing-out apparatus for ash when work, pulse valve 2 is opened, and is stored in compressed air moment in gas bag 1 by pulse valve 2, and ejection after injection tube 3 is directly injected to and in filter bag 4, carries out deashing; Pulse valve 2 cuts out, and winding-up finishes.The compressed air that gas bag 1 internal consumption falls, is constantly supplemented through gas bag air inlet pipe 5 by compressed air piping by source of the gas.
When a row (group) filter-bag blowing deashing finishes, the gas bag 1 being combined into one, pulse valve 2, injection tube 3, gas bag air inlet pipe 5 move to next row (group) filter bag top, and next row (group) filter bag is carried out to jetting deashing, by that analogy until finish.
