Description
Technical field:
The utility model relates to a kind of automatic control device, relates in particular to a kind of automation cell formula intelligent gas impulse ash blower that is applied in the boiler soot-blowing process.
Background technology:
In the boiler soot-blowing technical field, adopt the impulse soot blowing state of the art at present:
One, basic principle:
Constitute source of the gas by tow channel gas, the one tunnel is combustible gas, and another road is an air.Tow channel gas converges the formation gaseous mixture through control, arrives and is stored in the generator.Inflation through special time, the mist volume ratio and the quantity of expectation or calculating generator are suitable, in the time of can carrying out work, then igniting, flame quickens to pass to generator by the road, and the detonation of gaseous mixture gas produces shock wave in generator, thermal current, seismic wave, through spout with lead the as wide as possible heat-transfer surface of dust stratification of energy, to remove various types of dust stratifications on the heat-transfer surface, to improve heat exchange efficiency.
Two, present product category and the present situation of impulse ash blower:
Present impulse ash blower product type, tandem, parallel two classes;
(1), the tandem impulse ash blower basic element of character is formed:
Tandem is meant the connecting relation of critical piece in the impulse ash blower, refers in particular to mixing chamber and distributor, and these two parts are that forward and backward coupled in series or mixing chamber serial connection igniter are connected in series the distributor situation again, are commonly defined as the tandem impulse ash blower.On the general custom, from behind air slide valve and the combustible gas distributing valve to this section general designation of mixing point firearm along separate routes.Be referred to as main road before this.As shown in Figure 1: generally have in this device:
1, two-way source of the gas, a tunnel is combustible gas (available combustible gas (C
2H
2), hydrogen (H
2), methane, natural gas, petrochemical industry by-product dry gas etc.), another road is air (compressed air, a boiler air inducing), this two-way gas respectively has control valve (main valve) to control its volume flow;
2, mixing chamber (or be blending tank, generally be the container through particular design), tow channel gas converge fully at mixing chamber and mix;
3, igniter (or the electronic ignition element that makes igniter head, transformer or electronic circuit constitute), by pipeline, be installed in series after mixing chamber, in the moment of setting, light gaseous mixture, it is made up of igniter head, firing circuit and igniting container;
4, distributor (or cry and distribute header, the allocation set case), be the device that one road gas is divided into a plurality of shunt.Each has motor-operated control valve to control the switch and the closure of this shunt along separate routes, and it generally is connected on the igniter back with pipeline or goes here and there in the mixing chamber back;
5, impulse generator (or cry Impulsive tank, blast jar), be used for the gaseous mixture that temporary front shunt canalisation is sent, after igniter is lighted gaseous mixture, fire finally passes to this impulse generator, in this impulse generator, produce detonation, will mix the shock wave of its detonation generation, the dust stratification face that the thermal current guiding need be blown ash from the spout of this impulse generator;
6, controller, generally move control, control and will blow grey branch apparatus by relay circuit or PLC paired pulses soot blower.
Among Fig. 1: X0, Y0 are main valve, X1, Y1 pressure transmitter or flowmeter, and X2, Y2 debug valve, the W0 mixing chamber, W1 point cupping jar, the W4 igniter, the W2 distributor, WA1, WA2......WAN be motor-driven valve along separate routes, WB1, WB2......WBN generator.
This is the maximum version of impulse ash blower in the market, has quantitatively accounted for the domestic market by producer and has accounted for domestic 85%-90%.
In-line obvious weakness:
Since the tandem impulse ash blower through the application in surplus the domestic manufacturers nearly ten years, exposed extremely significantly security vulnerabilities and technology leak,
1, as mixing chamber apart from combustible gas gas source hypotelorism, distance is transmitted in combustion gas, tempering control is difficult;
2, lack safeguard protection buffering level on the fuel gas path, very easily when the mixing chamber tempering takes place, jeopardize gas source, cause major break down.
3, each air feed along separate routes, all control by the pulse valve of main road, when mixing chamber generation tempering, have only when each shunt that is connected on the distributor and all blown ash, the main pulse valve could close gas, like this, the distributor connecting pipeline is many more, and the main road service life is long more, and the time of burning when producing tempering is long more, when especially attemperating unit lost efficacy, be easy to generate big security incident more.
4, in addition, cascaded structure can not be used the automated manner isolated fault, continuously service ability with blow ash content way amount and be inversely proportional to.It is many more to blow ash shunt (point), and fault rate is high more, and service ability is poor more continuously.
(2), the parallel impulse ash blower basic element of character is formed:
Because production firm and use manufacturer to have realized that all the tandem impulse ash blower has safe hidden danger and technical defective, so, also have in addition at present this impulse ash blower improved, produced modular parallel-connection structure,
Technological process in parallel is that distribution is air and flammable gas circuit earlier, be distributed into the shunt that quantity equates separately at main road earlier, correspondence is converged the formation gaseous mixture along separate routes one by one again, between the combustible gas shunt, between the air shunt, all the cellular structure that concerns in parallel between the gaseous mixture shunt.
As shown in Figure 2: configuration such as Fig. 1 of its constituent apparatus are basic identical, just the configuration that will constitute is structurally adjusted, in Fig. 2: X0, Y0 is a main valve, X1, Y1 is pressure transmitter or flowmeter (No. one device), X3, Y3 is a non-return valve, X4 is a spark arrester, XA, YA is a distributor, XA1 wherein, XA2......XAN, YA1, YA2......YAN is a distributing valve, XA2, XB2......XBN is a pulse valve, XA3, XB3......XN3 is a non-return valve, XA4, XB4......XN4 is a spark arrester, XA5, XB5......XN5 is an igniter, XA6, XB6......XBN is a blender, and W0 is a mixing chamber, and W1 is a cupping jar, W4 is an igniter, W2 is a distributor, WA1, WA2......WAN is the shunt motor-driven valve, WB1, WB2......WBN is a generator.On the basis of the present situation of the technology that provides as Fig. 1, the technology that this evolution of the technology that provides as Fig. 2 just will provide as Fig. 1 structurally improvement, do not further develop this structural advantage, only change textural association, gaseous mixture formation order, just mix earlier in-line, it is first separately along separate routes tow channel gas that reallocation makes into to explain as Figure 11, converge along separate routes with each again and form gaseous mixture (i.e. back mixing along separate routes earlier), plenum system is that each oneself controls air feed along separate routes, when tempering takes place, the time of burning has lacked, and the tandem that compares safety has just risen some level to safety on structure.
The open defect of parallel impulse ash blower:
Complete, independently configuration that in parallel each all has along separate routes, this change has also brought new problem, caused blender to roll up, igniter rolls up, motor-driven valve also rolls up, and by a large equipment, makes a plurality of skinny devices in a word, the unified domination of large equipment, the point that now each need be blown ash carries out single domination;
Like this:
1, caused parts many;
2, the outer leak source of combustible gas is many, and the trouble point also increases thereupon greatly, and it is many just to equal tempering point, and interior leak source also increases;
3, leakage in the generation, mute chance quick-fried, that leak outside have increased greatly;
4, after system was out of order, master control system did not have means in time to send information, control in time, and reliability, stability, continuous failure-free operation ability descend greatly, can only by manually, turn off the fault road after maintenance overhaul.
The gas source and flow amount supply feature of impulse soot blowing is pulsation (no matter being series and parallel), promptly gives and blows ash point air feed once, and igniting once discharges once again, fills once again; Igniting again discharges again, and so circulation is until having blown ash.So the combustible gas supply flow is one section one section (or one one), manual adjustments way or pressure transmitter when common tow channel gas mixing ratio is debugging.Flowmeter+proportioning valve, the mixing ratio control level of this method is very low, very on a large scale, discrete fluctuation, cause and stably to control combustible gas and be in mixing ratio under the various pressure, the mixing ratio of each inflation is all different and differ greatly, thereby air consumption is big, blows grey weak effect or instability.In addition, directly adding the proportional valve control flow on pipeline does not have positive effect, can not keep blowing grey intensity according to different dust stratification stability of characteristics ground, and generally be to adopt inflationtime to regulate, have little significance.Can not be at the following energy cascade of the prerequisite of same volume combustible gas.Can make mixing ratio stable also is that the main reason that causes miso-fire rate height (be that combustible gas molecule and hydrogen molecule do not have active combustion, mix by ratio.)
