Abstract
The utility model belongs to the technical field of the thermal explosion pulse soot blower, concretely relates to trigeminy fuel solenoid valve thermal explosion pulse soot blower mainly includes impulse generator, fuel pipeline, oxidant pipeline and gas mixture pipeline, has concatenated the fuel solenoid valve of two forward installations on the fuel pipeline, at the back of the fuel solenoid valve of these two forward installations, has still concatenated the fuel solenoid valve of reverse installation. The main advantage is that on the premise of not improving the internal leakage type tempering probability, the fuel pipeline, the fuel source and the forward-mounted duplex fuel electromagnetic valve can be effectively protected from being damaged and various adverse effects by explosion impact, explosion flame and high-temperature gas generated by explosion, and the safety and reliability of the thermal explosion pulse soot blower are greatly improved.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of three fuel magnetic valve heat exploding pulse sootblowers.
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., the earliest by the people of former Soviet Union utility model, 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.
Probability for leakage type tempering generation in reducing, the duplex magnetic valve that the fuel magnetic valve of heat exploding pulse sootblower generally all adopts two magnetic valves to be composed in series, existing this class duplex magnetic valve is that forward is installed mostly, be far longer than the supply gas pressure of fuel owing to blast pressure in the moment of pulse soot blower igniting blast, the high-temperature gas that blast impulse and explosive flame and blast produce can pass the duplex magnetic valve, brings following harm:
1. the high-temperature gas of blast impulse and explosive flame and blast generation is fuel conduit and fuels sources transmission to the upstream of fuel magnetic valve, constitutes serious security threat;
2. the high-temperature gas of blast impulse and explosive flame and blast generation can constitute infringement to the rubber seal of magnetic valve when passing the fuel magnetic valve, so very easily cause leaking in the fuel magnetic valve leakage type tempering in the initiation fuel magnetic valve for a long time;
3. blast impulse causes the moment of fuel magnetic valve flap to open and close, and emits one fuel gas after next-door neighbour's blast, not only wastes fuel, and causes the short tempering of breech, quickens the temperature rise of blender and gaseous mixture pipeline, more easily causes the tempering fault.
The utility model content
The purpose of this utility model is: a kind of three fuel magnetic valve heat exploding pulse sootblowers are provided, and with the prior art ratio, the probability that the tempering of leakage type took place in this heat exploding pulse sootblower can either reduce can be avoided above-mentioned defective again.
Scheme of the present utility model is: three fuel magnetic valve heat exploding pulse sootblowers, mainly comprise impulse generator, fuel conduit, oxidant pipeline and gaseous mixture pipeline, on fuel conduit, be serially connected with the fuel magnetic valve that two forwards are installed, the back of the fuel magnetic valve of installing at these two forwards also is serially connected with the fuel magnetic valve of reverse installation.
Two fuel magnetic valves that are serially connected in the front are identical with prior art, the probability that the tempering of leakage type takes place in can reducing, backmost the fuel magnetic valve of oppositely installing then after outage (closed type) or energising back (open type) can guarantee reverse normal turn-off, thereby the reverse impact that produces of the blast of can avoiding lighting a fire and pass the fuel magnetic valve, thereby avoid the above-mentioned defective of prior art with the explosive flame and the high-temperature gas of reverse impact.
Major advantage of the present utility model is: in not improving under the prerequisite of leakage type tempering probability; the duplex fuel magnetic valve that can effectively protect fuel conduit, fuels sources and forward to install is not subjected to the destruction and the various adverse effect of the high-temperature gas of blast impulse, explosive flame and blast generation, has increased substantially the security and the reliability of heat exploding pulse sootblower.
In order to reduce the size dimension of fuel magnetic valve, what described fuel magnetic valve preferably adopted all is the closed type magnetic valve.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is provided further instruction by most preferred embodiment.
Among the figure: 1. oxidant pipeline, 2. fuel conduit, 3,4,5. fuel magnetic valve, 6,7. pair silk, 8. gaseous mixture pipeline, 9. impulse generator.
The specific embodiment
Embodiment 1:
As shown in Figure 1, present embodiment mainly comprises oxidant pipeline 1, fuel conduit 2, gaseous mixture pipeline 8 and impulse generator 9, on fuel conduit 2, pass through silk 6,7, by being serially connected with three closed type fuel magnetic valves 3,4,5 behind the forward direction successively, wherein the fuel magnetic valve the 3, the 4th, and forward is installed, and fuel magnetic valve 5 is oppositely to install.Before igniting blast, as long as shutoff fuel magnetic valve 3,4,5, just can guarantee the two-way normal turn-off of the three magnetic valve groups formed by fuel magnetic valve 3,4,5, thereby avoid a series of infringements and the adverse effect that reverse impact brought of exploding.
In the present embodiment, fuel magnetic valve 3,4,5 can all or part ofly be a normal-open electromagnetic valve also.
