Compared with the prior art, the thermal explosion pulse soot-blowing device can spare special blowing air transmission pipelines, such as the fuel pipeline and the oxidant pipeline, not only reduces the total length of the transmission pipeline by one third, but also simplifies a transmission pipeline system of the pulse soot-blowing device, thereby improving the reliability of the pipeline system.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of heat exploding pulse sootblower with purging motor.
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, adopt air as blowing medium again, thereby having only a fuel conduit to be connected with blender or impulse generator with an air pipe line, this heat exploding pulse sootblower can only adopt oxidant gas as blowing medium.
My application number formerly is that the Chinese patent of 200810111689X has proposed a kind of three-tube type heat exploding pulse sootblower, 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 heat exploding pulse sootblower needs purge gas transfer pipeline special as fuel pump deliver line and oxidant transfer pipeline.
The utility model content
The purpose of this utility model is: a kind of heat exploding pulse sootblower with purging motor is provided, and this heat exploding pulse sootblower not only can adopt the oxidant outside the air, and can save the purging air transfer pipeline.
Scheme of the present utility model is: have the heat exploding pulse sootblower of purging motor, mainly comprise impulse generator, purging motor, fuel conduit and oxidant pipeline, purging motor, fuel conduit, oxidant pipeline are connected with impulse generator.
Have special oxidant pipeline, nature can adopt the oxidant outside the air; Have purging motor, nature can save special purging air transfer pipeline.
With the prior art ratio, the utility model can save purge gas transfer pipeline special as fuel pump deliver line and oxidant transfer pipeline, not only make the total length of transfer pipeline reduce about 1/3rd, and simplified the delivery pipeline system of pulse soot blower significantly, improved the reliability of pipe-line system.
In order to enlarge the performance space of pulse soot blower distribution and purging operation, on the connecting line of purging motor air outlet and impulse generator or other pipeline, can be serially connected with electronic or pneumatic on-off valve.
For fear of the influence of blast impulse, on the connecting line of purging motor air outlet and impulse generator or other pipeline, can be serially connected with non-return valve to purging motor.
