The main advantages of the method are that the flame propagation speed of the combustible premixed gas in the pulse generator in the length direction of the pulse generator is increased to be close to the current speed, the burnout time of the premixed gas is greatly shortened, and the explosion intensity and the soot blowing effect are improved.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of high speed ignition heat explosion pulse soot blower.
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.
Under the certain prerequisite of thermal explosion energy, the flame propagation velocity in the impulse generator is fast more, in it time that burns of gaseous mixture just short more, bursting strength is just high more, it is just good more to blow grey effect.In order to improve the flame propagation velocity in the impulse generator, all be provided with multiple tracks flame intensifier ring in the existing impulse generator along its length, its flame propagation velocity is the highest also can only to accelerate to local velocity of sound.
Application number is that 200520112623.4 utility model patent discloses a kind of deflagration tank, mainly be on impulse generator, to be provided with a plurality of ignition points along its length to light a fire simultaneously, because the connected mode between the spark ignition head of each ignition point of shortage is difficult to accomplish to light a fire simultaneously.
The utility model content
The purpose of this utility model is: a kind of high speed ignition heat explosion pulse soot blower is provided, and with the prior art ratio, along its length flame propagation velocity is higher in the impulse generator of this heat exploding pulse sootblower.
Scheme of the present utility model is: high speed ignition heat explosion pulse soot blower, mainly comprise impulse generator, at least three spark ignition heads and corresponding lead, wherein the spark ignition head is to disperse to be arranged in the impulse generator or on its wall towards the length direction of generator along the pulse, is connected in series by lead between each spark ignition head.
As everyone knows, the speed of electric current is 300,000 kilometer per seconds, because each spark ignition head is to arrange along the length direction of Impulsive tank, and be connected in series between each spark ignition head, along its length gaseous mixture flame propagation velocity is just near rate of current in the impulse generator, be higher than prior art far away, near 300,000 times to millions of times of prior art.
Major advantage of the present utility model is:
1. along its length flame propagation velocity in the impulse generator has been brought up near rate of current, greatly shortened burning the time of gaseous mixture significantly, thereby improved the bursting strength of gaseous mixture very significantly, had and better blow grey effect.
2. because igniter head is installed on the impulse generator or in it, be installed in after the blender near blender place ratio with common igniter head, the mixture homogeneity of the gaseous mixture at igniter head place is higher, fully mixes basically, does not have carbon deposit on igniter head substantially.
3. because igniter head is installed on the impulse generator or in it, be installed in after the blender near blender place ratio with common igniter head, even only close fuel and do not close oxidant at igniter, its ignition success rate also can be up to 100%.
In order to realize the purpose of this utility model better, described high speed ignition pulse soot blower preferably also comprises fire rod, this fire rod is arranged in the impulse generator towards the length direction of generator along the pulse, described spark ignition head is fixed on this fire rod along the length direction of fire rod, in order to improve reliability, preferably also be cast with the insulation casting glue in the fire rod.
In order to realize the purpose of this utility model better, the quantity of described spark ignition head preferably equals more than or equal to 6.
