Abstract
The utility model belongs to the technical field of thermal explosion pulse soot blowing, and particularly relates to an improved distributed three-tube thermal explosion pulse blower which mainly comprises at least two pulse blowing units, at least two fuel branch tubes, an oxidant gas branch tube, a blow gas line, a fuel distribution header and an oxidant gas distribution header. Each pulse blowing unit is connected with a port of a corresponding distribution header through the fuel which only belongs to the pulse blowing unit and through the oxidant gas branch tube, to which the port only belongs. The blow gas line adopts a tree-type structure. The positive point is that the improved distributed three-tube thermal explosion pulse blower combines the properties of safety, reliability and economy.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of improved distributed type three-pipe heat explosion pulse ash-blowing device, particularly relates to the distributed type three-pipe heat explosion pulse ash-blowing device that a kind of fuel conduit and oxidant gas pipeline adopt parallel construction.
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 a kind of improved distributed type three-pipe heat explosion pulse ash-blowing device for the impulse generator group.
Scheme of the present utility model is: improved distributed type three-pipe heat explosion pulse ash-blowing device, mainly comprise at least two impulse soot blowing unit and fuel manifold, the oxidant gas house steward, the purge gas pipeline, the fuel arm, the oxidant gas arm, and fuel distributes header, oxidant gas distributes header, each impulse soot blowing unit all has independently purge gas pipeline, oxidant gas pipeline and fuel conduit, fuel manifold, the oxidant gas house steward distributes header with fuel respectively, oxidant gas distributes the import of header to be connected, the fuel inlet of each impulse soot blowing unit, the oxidant gas import is all respectively by only belonging to the fuel arm of this impulse soot blowing unit, the oxidant gas arm distributes header with corresponding fuel, oxidant gas distributes the interface that only belongs to this arm of header to be connected, the purge gas pipeline is connected with the purge gas inlet of each impulse soot blowing unit, and what the purge gas pipeline adopted 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 each fuel arm, each oxidant gas arm all is exclusive, once the impulse soot blowing unit generation problem that a certain road arm or its are connected, only need close the respective valves of distributing on the header gets final product, can not influence the operate as normal of other impulse soot blowing unit, and purge gas because the air that adopts more, very little to Influence on security, adopt tree can simplify pipeline structure, improve reliability, reduce cost.
