Abstract
The invention belongs to the thermal explosion pulse sootblowing technical field, and in particular relates to a dendritical pipeline shared three-tube thermal explosion pulse sootblower, mainly comprising pulse generator sets, an air distributing device and a mixed gas main pipe, wherein, at least two pulse generator sets are arranged, and each pulse generator set is connected with the mixed gas main pipe through a two-way valve and an exclusive mixed gas branch pipe; the two-way valve is close to the pulse generator set the exclusive mixed gas branch pipe of which is connected with the two-way valve in series; and the air distributing device is provided with a fuel pipeline, an oxidant gas pipeline and a sweeping gas pipeline. The dendritical pipeline shared three-tube thermal explosion pulse sootblower has the advantages that when the number of the pulse generator sets in the three-tube thermal explosion pulse sootblower applied by the author is more than one, a feasible total system structure is provided, because of the shared air distributing device and the adoption of the dendritical structure of the mixed gas pipeline, the three-tube thermal explosion pulse sootblower has low cost.
Description
Technical field
The invention belongs to the heat explosion pulse ash-blowing technical field, be specifically related to a kind of tree-shaped pipeline sharing type three-pipe heat explosion pulse ash-blowing device.
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.
The author's patent application has formerly proposed a kind of three-tube type heat exploding pulse sootblower, its application number is to have increased special purge gas pipeline outside the 200810111689X pipeline again, thereby, heat exploding pulse sootblower lays a good foundation for adopting other oxidant outside the air and other purge gas outside the oxidant, for wide space has been expanded out in the further research and development of heat exploding pulse sootblower, but this patent application proposes is actually one and basic blows grey unit, and wherein the part outside the impulse generator is actually a three-tube type distribution igniter.
Summary of the invention
The objective of the invention is to: in two or more situations, on the basis of foregoing invention, propose tree-shaped pipeline sharing type three-pipe heat explosion pulse ash-blowing device for the impulse generator group.
The solution of the present invention is: tree-shaped pipeline sharing type three-pipe heat explosion pulse ash-blowing device 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, all moving or operated pneumatic valve and exclusive gaseous mixture arm are connected with the gaseous mixture person in charge each impulse generator group by two energisings, moving or the affiliated impulse generator group of close its exclusive gaseous mixture arm that is connected in series of operated pneumatic valve of this two energising, air distributing device has fuel conduit, oxidant gas pipeline and purge gas pipeline.
Positive part of the present invention is: for the author's application number provides a kind of practicable general system set-up for the patent of 200810111689X during more than one in the quantity of impulse generator group, adopt tree owing to share air distributing device and gaseous mixture pipeline, its cost is lower.
