Abstract

The utility model belongs to the field of thermal explosion pulse soot-blowing technology, in particular to a tree-shaped pipeline distribution type three-pipe thermal explosion pulse soot-blowing device which mainly comprises at least two pulse soot-blowing units, a fuel pipeline, an oxidant air pipeline and a blowing air pipeline, wherein the fuel pipeline, the oxidant air pipeline and the blowing air pipeline are respectively connected with a fuel inlet of each pulse soot-blowing unit, an oxidant air inlet and a blowing air inlet; and the fuel pipeline, the oxidant air pipeline and the blowing air pipeline all adopt tree-shaped structures. The tree-shaped pipeline distribution type three-pipe thermal explosion pulse soot-blowing device has the advantages that the pulse soot-blowing device provides a practical overall system structure for the three-pipe thermal explosion pulse soot-blowing device previously applied by the author when the number of the pulse generator is more than one; and because the fuel pipeline, the oxidant air pipeline and the blowing air pipeline adopt the tree-shaped structures, the total length of the pipeline is simple than a parallel pipeline structure, and the security and the reliability are much higher.

Description

Tree-shaped pipeline distributed type three-pipe heat explosion pulse ash-blowing device

Technical field

The utility model belongs to the heat explosion pulse ash-blowing technical field, is 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.

The utility model content

The purpose of this utility model is: in two or more situations, on the basis of above-mentioned utility model, propose tree-shaped pipeline distributed type three-pipe heat explosion pulse ash-blowing device for the impulse generator group.

Scheme of the present utility model 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 utility model 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.
