Abstract
The invention belongs to the thermal explosion pulse soot blowing technical field and in particular relates to a dentritic pipeline distributed three-tube thermal explosion pulse soot blower. The soot blower mainly comprises at least two pulse soot blowing units, fuel pipelines, oxidant gas pipelines and sweeping gas pipelines; the fuel pipeline, the oxidant gas pipeline and the sweeping gas pipeline are respectively connected with a fuel inlet, an oxygen gas inlet and a sweeping gas inlet of each pulse soot blowing unit; the fuel pipeline, the oxygen gas pipeline and the sweeping gas pipeline respectively adopt a dentritic structure. The dentritic pipeline distributed three-tube thermal explosion pulse soot blower has the advantages of providing a practical and feasible overall system structure for an applicant when the three-tube thermal explosion pulse soot blower previously applied by the applicant has more than one pulse generator set; as the fuel pipeline, the oxygen gas pipeline and the sweeping gas pipeline adopt the dentritic structure; the total length of the pipelines is much smaller than a parallel pipeline structure and the safety and reliability is much higher.
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 distributed 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 200810111689X, mainly be outside fuel conduit, oxidant pipeline, to have increased special purge gas 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 propose be actually one and basic blow grey unit.
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 distributed type three-pipe heat explosion pulse ash-blowing device for the impulse generator group.
The solution of the present invention is: tree-shaped pipeline distributed type three-pipe heat explosion pulse ash-blowing device, mainly comprise at least two impulse soot blowing unit and fuel conduit, the oxidant gas pipeline, the purge gas pipeline, each impulse soot blowing unit all has independently purge gas pipeline, oxidant gas pipeline and fuel conduit, fuel conduit is connected with the fuel inlet of each impulse soot blowing unit, the oxidant gas pipeline is connected with the oxidant gas import of each impulse soot blowing unit, the purge gas pipeline is connected fuel conduit with the purge gas inlet of each impulse soot blowing unit, the oxidant gas pipeline, what the purge gas pipeline adopted all is tree.
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, because what fuel conduit, oxidant gas pipeline, purge gas pipeline adopted all is tree, the pipeline total length is than simple and direct many of parallel pipeline structure, and security and reliability are also much higher.
Description of drawings
Below in conjunction with accompanying drawing, the present invention is provided further instruction by embodiment.
Accompanying drawing 1 is the schematic diagram of the embodiment of the invention.
Among the figure: 1,2,3,4,5,6,7,8. impulse soot blowing unit, 9. fuel conduit, 10. oxidant gas pipeline, 11. purge gas pipelines.
The specific embodiment
As shown in Figure 1, heat exploding pulse sootblower mainly comprises impulse soot blowing unit 1,2,3,4,5,6,7,8 and fuel conduit 9, oxidant gas pipeline 10, purge gas pipeline 11, fuel conduit 9 and each impulse soot blowing unit 1,2,3,4,5,6,7,8 fuel inlet is connected, oxidant gas pipeline 10 and each impulse soot blowing unit 1,2,3,4,5,6,7,8 oxidant gas import is connected, purge gas pipeline 11 and each impulse soot blowing unit 1,2,3,4,5,6,7,8 purge gas inlet is connected, fuel conduit 9, oxidant gas pipeline 10, what purge gas pipeline 11 adopted all is tree.
