Abstract
The invention belongs to the thermal explosion pulse soot blowing technology field and particularly relates to a tree-like pipeline shared thermal explosion pulse soot blower which mainly comprises pulse generator groups, a gas distribution device and a mixed gas main pipe; the number of the pulse generator groups is at least two, each pulse generator group comprises at least one pulse generator, each pulse generator group is connected with the mixed gas main pipe by a two-way electric or pneumatic valve and a special mixed gas branch pipe, the two-way electric or pneumatic valve is near to the pulse generator group, to which a serially-connected special mixed gas branch pipe thereof belongs; the main advantage is that the tree-like pipeline shared thermal explosion pulse soot blower of the invention can not only retain the advantages of the shared thermal explosion pulse soot blower, but also overcome the shortcomings of the complicated pipeline system of the prior shared thermal explosion soot blower, thereby greatly reducing the total length of the mixed gas pipeline.
Description
Technical field
The invention belongs to the heat explosion pulse ash-blowing technical field, be specifically related to tree-shaped pipeline sharing type heat explosion impulse blower.
Background technology
Heat exploding pulse sootblower is called for short pulse soot blower, have another name called the shock-wave ash blowing device, the shock wave soot blower, weak quick-fried soot blower, blast wave blower, the detonation wave soot blower, pinking pulse soot blower etc., invent by the people of the former Soviet Union the earliest, imported China in 1988 into, develop by " gas big gun ", its basic principle of blowing ash is: the gaseous mixture that makes fuel and oxidant gas with impulse generator that flue is communicated with in light a fire and explode, utilize " the alternation punching press is inhaled and drawn effect " of the compression shock ripple of blast generation, " the purging effect " of " physics effect of micro-explosion " and high-speed pulse jet blown down the various dust stratifications on boiler heating surface and the flue wall, has vibration simultaneously concurrently, three kinds of deashing effects of sound wave and high temperature pyrolysis.Impulse generator claims shock wave generator, surge generator, blast wave generator, detonation wave generator, blast jar, Impulsive tank etc. again; Impulse generator can directly be communicated with flue, also can be communicated with flue by pulse conduit, and pulse conduit claims transmitting tube, jet pipe etc. again.Because belonging to dry type blows ash, and blow that grey intensity height, no dead angle, sphere of action are big, good energy-conserving effect, equipment dependability height, to blow grey expense cheap, has impayable superiority with traditional steam soot blowing ratio, not only be used for heated surface at the end of boiler at large and replaced traditional steam soot blowing, and begin to be used to blow down industrial furnace interior dust stratification and slagging scorification, even also attempted being used for other occasions such as auxiliary deashing of electrostatic precipitator.
It is so-called that to share the formula heat exploding pulse sootblower be exactly the heat exploding pulse sootblower of each impulse generator or all shared air distributing device of impulse generator group, for example application number be 2004200045324 utility model patent disclosed be exactly a kind of shared formula heat exploding pulse sootblower.Existing shared formula pulse soot blower all comprises distributor, each impulse generator or impulse generator group are all shared an air distributing device by distributor, owing to need exclusive gaseous mixture pipeline from distributor to each impulse generator or impulse generator group, between these exclusive gaseous mixture pipelines is arranged side by side, be called the parallel pipeline structure, the gaseous mixture pipeline of this pulse soot blower is complicated, and total length is longer.
Summary of the invention
The objective of the invention is to: a kind of tree-shaped pipeline sharing type heat explosion impulse blower is provided, and the gaseous mixture pipeline of this pulse soot blower is simple, total length is shorter.
The solution of the present invention is: tree-shaped pipeline sharing type heat explosion impulse blower mainly comprises impulse generator group, air distributing device and the gaseous mixture person in charge; The quantity of impulse generator group is at least two, each impulse generator group comprises an impulse generator at least, each impulse generator group all by two energisings moving or operated pneumatic valve and exclusive gaseous mixture arm be responsible for gaseous mixture and be connected, the moving or operated pneumatic valve of this two energising is near the affiliated impulse generator group of its exclusive gaseous mixture arm that is connected in series.
Moving or the close impulse generator group of operated pneumatic valve of two energisings, the distributor that is equivalent to share the formula impulse generator is cut apart and is distributed near each impulse generator group, the gaseous mixture arm that is specific to the impulse generator group like this is just very short, the gaseous mixture person in charge has only then shared by each impulse generator group, with shared formula pulse soot blower ratio, gaseous mixture pipeline system has just been simplified significantly, and the total length of gaseous mixture pipeline has also reduced significantly.
The present invention provides a kind of shared formula heat exploding pulse sootblower that adopts the tree-shaped pipeline structure first, the advantage that has promptly kept shared formula heat exploding pulse sootblower, overcome the deficiency of existing shared formula heat exploding pulse sootblower pipe-line system complexity again, reduced the total length of gaseous mixture pipeline significantly, for the medium-sized heat exploding pulse sootblower of a cover, the total length of gaseous mixture pipeline of the present invention often has only and adopts 1/tens even 1/tens of parallel pipeline structure.
Described two energising movable valves are the moving ball valve of two energisings preferably.
In order to improve reliability, air distributing device is preferably two parallel connections.
Described air distributing device also can comprise igniter.
Description of drawings
Below in conjunction with accompanying drawing, the present invention is provided further instruction by most preferred embodiment.
Accompanying drawing 1 is the schematic diagram of most preferred embodiment of the present invention.
Among the figure: 1,2,3. impulse generator group, 4,5, the 6. exclusive gaseous mixture arm of impulse generator group, the moving ball valve of 7,8,9. two energisings, 10. gaseous mixture is responsible for, the exclusive gaseous mixture arm of 11,12. air distributing devices, 13,14. electrical ball valves, 15,16. air distributing devices, 17. impulse generators.
The specific embodiment
Most preferred embodiment:
As shown in Figure 1, heat exploding pulse sootblower mainly comprises impulse generator group 1,2,3, the gaseous mixture person in charge 10 and air distributing device 15,16; Each impulse generator group all comprises two impulse generators 17; Impulse generator group 1,2,3 is responsible for 10 by exclusive gaseous mixture arm 4,5,6 of impulse generator group and gaseous mixture respectively and is connected, and is serially connected with the moving ball valve 7,8,9 of two energisings on the exclusive gaseous mixture arm 4,5,6 of impulse generator group respectively; All include igniter in the air distributing device 15,16, air distributing device 15,16 is connected by the import that exclusive gaseous mixture arm 11,12 and gaseous mixture are responsible for respectively, is serially connected with electrical ball valve 13,14 respectively on the exclusive gaseous mixture arm 11,12 of air distributing device.
15,16 1 of air distributing devices are standby with one, when certain set of pulses generator need blow grey operation, can open the moving ball valve of the energising of two on the exclusive gaseous mixture arm of this impulse generator group, and make the moving ball valve of the energising of two on the exclusive arm of other impulse generator group be in closed condition, blow grey operation then.
