Abstract
The invention belongs to the thermal explosion pulse sootblowing technical field, and in particular relates to a parallel pipeline distributed thermal explosion pulse sootblower for dispersedly supplying sweeping air, mainly comprising at least two pulse sootblowing units, a fuel main pipe, an oxidant main pipe, fuel branch pipes, oxidant branch pipes, a fuel distribution channel and an oxidant distribution channel, wherein, a fuel inlet and an oxidant inlet of each pulse sootblowing unit are communicated with corresponding exclusive ports of the fuel distribution channel and the oxidant distribution channel respectively through the exclusive fuel branch pipes and the exclusive oxidant branch pipes; and each pulse sootblowing unit comprises a blowing draught fan. The parallel pipeline distributed thermal explosion pulse sootblower has the advantages that: as a patent item applied by the author with the application number of 20081011211.1, a feasible total system structure is provided when the number of the pulse generator sets is more than one, the reliability is higher, and the whole set of an air blowing pipeline with a parallel structure is saved.
Description
Technical field
The invention belongs to the heat explosion pulse ash-blowing technical field, be specifically related to a kind of parallel pipeline distributed type thermal explosion combustion pulse soot blower, particularly relate to a kind of parallel pipeline distributed type thermal explosion combustion pulse soot blower of decentralized supply purging air.
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.
Heat exploding pulse sootblower wanted paired pulses generator inner chamber to purge before charging into fuel and oxidant gas in impulse generator at every turn usually.Existing heat exploding pulse sootblower had both adopted air as oxidant, adopted air as blowing medium again, thereby had only a fuel conduit and an air pipe line, and this heat exploding pulse sootblower can only adopt oxidant gas as blowing medium.
The author's application number is that 2008101121101 patent application has proposed a kind of heat exploding pulse sootblower with purging motor, have independently fuel conduit and oxidant gas pipeline and utilize blower fan as source purge gas, not only can adopt the oxidant gas outside the air, and saved special purge gas transfer pipeline, this patent application proposes is actually a basic impulse soot blowing unit.
Summary of the invention
The objective of the invention is to: in two or more situations, is on the basis of 2008101121101 patent for the impulse generator group at application number, proposes a kind of parallel pipeline distributed type heat exploding pulse sootblower of decentralized supply purging air.
The solution of the present invention is: the parallel pipeline distributed type heat exploding pulse sootblower of decentralized supply purging air, mainly comprise at least two impulse soot blowing unit, and fuel manifold, the oxidant gas house steward, the fuel arm, the oxidant gas arm, and fuel distributes header, oxidant gas distributes header, 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, and each impulse soot blowing unit all includes purging motor.
Positive part of the present invention is: for the author's application number provides a kind of practicable general system set-up for 2008101121101 patent during more than one in the quantity of impulse generator group, because fuel conduit and oxidant gas pipeline all adopt parallel construction, once some impulse soot blowings unit generation problem, only need close and blow fuel arm that grey unit is connected with this and the fuel cock valve and the oxidant gas switch valve of oxidant gas arm front end gets final product, other blows grey unit still can normally blow grey operation, and owing to adopting purging motor decentralized supply purging air to save the purge gas transfer pipeline, saved the air purge pipeline of a whole set of parallel construction, cost is also reduced effectively.
