The method has the advantages that: the tree-shaped pipeline shared pulse soot blower is improved, so that the air inflation ratio of the soot blower is always kept near the optimal ratio, the soot blowing effect is very stable, and the problem of carbon precipitation and carbon deposition caused by over-concentration of fuel can be solved.
Description
Technical field
The invention belongs to the heat explosion pulse ash-blowing technical field, be specifically related to a kind of constant-current tree-shaped pipeline sharing type 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 application number by name be 2008101116917 in first to file a kind of tree-shaped pipeline sharing type heat explosion impulse blower has been proposed, mainly be that the gaseous mixture pipeline adopts tree, all be serially connected with the moving or operated pneumatic valve of two energisings connecting on the final stage gaseous mixture arm of each impulse generator group, its major advantage is to have abandoned distributor, the mixed gas pipeline road is very simple, its shortcoming is: because each impulse generator group is distributed in the different parts of boiler, the path difference of each impulse generator group inflation is very big, thereby the difference of its circulating resistance is also very big, maximum can differ from several times, flow of aerating air difference great disparity when causing each impulse generator group to blow grey operation, the proportioning difference great disparity of gaseous mixture when finally causing each impulse generator group to blow grey operation, fuel overrich or cross and rarely all to have a strong impact on explosion energy and bursting strength and finally to influence explosive effect also can cause the serious carbon deposit charcoal of analysing in addition during the fuel overrich.
Summary of the invention
The objective of the invention is to: a kind of constant-current tree-shaped pipeline sharing type heat explosion pulse ash-blowing device is provided, and the uniformity of the flow of aerating air of each impulse generator group of this heat exploding pulse sootblower is better.
The solution of the present invention is: constant-current tree-shaped pipeline sharing type heat explosion pulse ash-blowing device mainly comprises impulse generator group, air distributing device or distribution igniter and the gaseous mixture person in charge; The quantity of impulse generator group is at least two, each impulse generator group comprises an impulse generator at least, all moving or operated pneumatic valve and exclusive gaseous mixture arm are connected with the gaseous mixture person in charge each impulse generator group by two energisings, moving or the affiliated impulse generator group of close its exclusive gaseous mixture arm that is connected in series of operated pneumatic valve of this two energising all is serially connected with restricting orifice or control valve on the exclusive gaseous mixture arm of each impulse generator group.
Owing to all be serially connected with restricting orifice or control valve on the exclusive gaseous mixture arm of each impulse generator group, the restricting orifice that can be by selecting suitable throttle diameter or the suitable aperture of control valve are adjusted the resistance of exclusive gaseous mixture arm, thereby the flow of aerating air of each impulse generator group is kept substantially always, thereby the uniformity of its flow of aerating air is better.
Positive part of the present invention is: the tree-shaped pipeline sharing type pulse soot blower is improved, its inflation proportioning is maintained near the best proportioning all the time, it is very stable to blow grey effect, also can eliminate the carbon deposit charcoal problem of analysing that causes because of the fuel overrich.
