Abstract
The utility model belongs to the field of thermal explosion pulse soot-blowing technology, in particular to a distributing type thermal explosion fuel pulse soot-blowing device which disperses, supplies and blows the air. The distributing type thermal explosion fuel pulse soot-blowing device mainly comprises at least two pulse soot-blowing units, a fuel pipeline and an oxidant pipeline, wherein each pulse soot-blowing unit comprises a blowing air blower; the fuel pipeline and the oxidant air pipeline are respectively communicated with a fuel inlet of each pulse soot-blowing unit and an oxidant air inlet; and the fuel pipeline and the oxidant air pipeline adopt tree-shaped structures. The distributing type thermal explosion fuel pulse soot-blowing device has the advantages that a fuel distribution linkage box is completely discarded; the fuel pipeline adopts the tree-shaped structure; sidpersing type air supply is adopted and an air transmission pipeline is cancelled; the entire pipeline system becomes extremely simple; and the security and the reliability of the pipeline system are greatly enhanced.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of distributed heat detonation pulse soot blower, particularly relates to a kind of distributed heat detonation pulse soot blower of decentralized supply combustion 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 is divided into two kinds from overall system: a kind of is that a plurality of impulse generator groups are passed through the shared air distributing device of gaseous mixture distributor, is called and shares the formula heat exploding pulse sootblower; Another kind of then be that each impulse generator group all is furnished with exclusive air distributing device, be called distribution type heat explosion pulse ash-blowing device.Distribution type heat explosion pulse ash-blowing device is further divided into parallel pipeline distributed type heat exploding pulse sootblower and tree-shaped pipeline distributed type heat exploding pulse sootblower again, the former has fuel and distributes header and air to distribute header, distributing header fuel conduit and air pipe line afterwards all is exclusive pipeline, between the exclusive pipeline of each fuel and all be coordination between the exclusive pipeline of each air, its pipe-line system is very complicated; Latter's fuel of then having sublated distributes header and air to distribute header, and fuel conduit and air pipe line all adopt simple and direct tree.
Existing distribution type heat explosion pulse ash-blowing device is by air pipe line centralizedly supply combustion air mostly, needs more long air pipe line.Application number is the deflagration pulse soot blower that 2005100829152 Chinese patent discloses a kind of decentralized supply combustion air, mainly be that each impulse generator group all is furnished with exclusive blower fan, thereby saved the pipeline of centralizedly supply combustion air, simplified the pipe-line system of distribution type heat explosion pulse ash-blowing device significantly, but the fuel conduit of this heat exploding pulse sootblower has still adopted parallel construction, still remain with fuel and distribute header, the fuel conduit more complicated, the pipeline total length is longer.
The utility model content
The purpose of this utility model is: a kind of distribution type heat explosion pulse ash-blowing device of decentralized supply combustion air is provided, and the fuel conduit total length of this heat exploding pulse sootblower is shorter.
Scheme of the present utility model is: the distribution type heat explosion pulse ash-blowing device of decentralized supply combustion air, mainly comprise fuel conduit and at least two impulse soot blowing unit, each impulse soot blowing unit all includes blower fan, fuel conduit is connected with the fuel inlet of each impulse soot blowing unit, and what fuel conduit adopted is tree.
With the pipe-line system ratio of parallel construction, the pipe-line system of tree can sharedly be responsible for, and pipeline total length nature is more than the parallel construction weak point.
Major advantage of the present utility model is:
1. fuel conduit adopts tree, makes system of fuel lines obtain great simplification, and pipe internal memory tolerance and leak hidden danger and reduce significantly makes the security of fuel conduit obtain the raising of essence.
2. thoroughly abandoned fuel and distributed header and fuel distributing valve, made the reliability of system of fuel lines obtain the raising of essence.
3. because each impulse soot blowing unit all includes blower fan, completely abolished the air delivery pipe road, made the whole pipe-line system of heat exploding pulse sootblower obtain further greatly simplifying.
4. because each impulse soot blowing unit all includes blower fan, a blower fan generation problem of blowing grey unit can not influence the operate as normal that other blows grey unit.
5. cancelled a large amount of air slide valves and complicated and long combustion air distribution circuit, the power consumption of blower fan has also reduced significantly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is provided further instruction.
Fig. 1 is the system schematic of the utility model embodiment.
1. fuel conduits among the figure, 2,3,4,5,6,7,8,9,10. impulse soot blowing unit.
The specific embodiment
As shown in Figure 1, the heat exploding pulse sootblower of present embodiment comprises fuel conduit 1 and heat explosion pulse ash-blowing unit 2,3,4,5,6,7,8,9,10, and each heat explosion pulse ash-blowing system all includes blower fan, and what fuel conduit 1 adopted is tree.
Claims (1)
