Abstract
The utility model belongs to the technical field of the thermal explosion pulse soot blower, concretely relates to trigeminy oxidant solenoid valve thermal explosion pulse soot blower mainly includes impulse generator, fuel pipeline, oxidant pipeline and gas mixture pipeline, has concatenated the oxidant solenoid valve of two forward installations on the oxidant pipeline, at the back of the oxidant solenoid valve of these two forward installations, has still concatenated the oxidant solenoid valve of reverse installation. The dual-oxidant electromagnetic valve has the main advantages that on the premise of not improving the internal leakage probability of the oxidant electromagnetic valve, the oxidant pipeline, the oxidant source and the forward-mounted dual-oxidant 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 the reliability of the thermal explosion pulse soot blower are effectively 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 oxidant 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.
In order to reduce the interior leakage probability of oxidant magnetic valve, the duplex magnetic valve that the oxidant magnetic valve of heat exploding pulse sootblower generally all adopts two magnetic valves to be composed in series, existing this class duplex magnetic valve all is that forward is installed, in moment of pulse soot blower igniting blast since blast pressure often greater than the supply gas pressure of oxidant, the high-temperature gas that blast impulse and explosive flame and blast produce can pass duplex oxidant magnetic valve, brings following harm:
1. the high-temperature gas of blast impulse and explosive flame and blast generation is oxidant pipeline and oxidizer source transmission to the upstream of fuel magnetic valve, constitutes certain 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 oxidant magnetic valve, so very easily cause for a long time leaking in the oxidant magnetic valve;
3. blast impulse causes the moment of fuel magnetic valve flap to open and close, and emits one oxidant after next-door neighbour's blast, causes the waste of oxidant.
The utility model content
The purpose of this utility model is: a kind of three oxidant magnetic valve heat exploding pulse sootblowers are provided, and with the prior art ratio, this heat exploding pulse sootblower can either reduce the oxidant magnetic valve the interior probability that leaks takes place, and can avoid above-mentioned defective again.
Scheme of the present utility model is: three oxidant magnetic valve heat exploding pulse sootblowers, mainly comprise impulse generator, fuel conduit, oxidant pipeline and gaseous mixture pipeline, on the oxidant pipeline, be serially connected with the oxidant magnetic valve that two forwards are installed, the back of the oxidant magnetic valve of installing at these two forwards also is serially connected with the oxidant magnetic valve of reverse installation.
Two oxidant magnetic valves that are serially connected in the front are identical with prior art, can reduce the probability that leaks in the oxidant magnetic valve, backmost the oxidant 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 oxidant 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: leak in not improving the oxidant magnetic valve under the prerequisite of probability; the duplex oxidant magnetic valve that can effectively protect oxidant pipeline, oxidizer source 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 improved the security and the reliability of heat exploding pulse sootblower.
In order to reduce the size dimension of oxidant magnetic valve, what described oxidant 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. fuel conduit, 2. oxidant pipeline, 3,4,5. oxidant 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 fuel conduit 1, oxidant pipeline 2, gaseous mixture pipeline 8 and impulse generator 9, on oxidant pipeline 2, pass through silk 6,7, by being serially connected with three closed type oxidant magnetic valves 3,4,5 behind the forward direction successively, wherein the oxidant magnetic valve the 3, the 4th, and forward is installed, and oxidant magnetic valve 5 is oppositely to install.Before igniting blast, as long as shutoff oxidant magnetic valve 3,4,5, just can guarantee the two-way normal turn-off of the three magnetic valve groups formed by oxidant 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, oxidant magnetic valve 3,4,5 can all or part ofly be a normal-open electromagnetic valve also.
