Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, when not conflicting, the feature in the utility model embodiment and embodiment can combine mutually.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
device embodiment
Referring to figs. 1 through 3, it illustrates composition and the structure of many burners gasification installation of the present embodiment, this many burners gasification installation comprises: vapourizing furnace reaction chamber 40, main burner 10 and auxiliary burning nozzle 20.Main burner 10 is arranged at the top center of vapourizing furnace reaction chamber 40, auxiliary burning nozzle 20 is arranged in the circumference of main burner 10, auxiliary burning nozzle 20 has multiple interface channel, and is provided with and feeds intake the control valve switched between pattern in go into operation pattern and technique of igniting for control interface passage.
In above-described embodiment, many burners gasification installation adopts the layout mounting means of many burners, can be evenly arranged multiple auxiliary burning nozzle 20, realize the pressurized gasification of coal water slurry or fine coal in gasification installation top circumference.Wherein, auxiliary burning nozzle 20 not only can be lighted a fire and be gone into operation, and according to the load condition of gasification installation, selectively auxiliary burning nozzle 20 can also be switched to process burner pattern from igniting startup burner pattern.Like this, before feeding intake, auxiliary burning nozzle 20 goes into operation ignition mode, carries out increasing temperature and pressure, the response capacity of vapourizing furnace reaction chamber 40 is increased to vapourizing furnace reaction chamber 40, and vapor pressure improves, and then shortens furnace drying time.
In addition, when main burner 10 startup feeds intake, auxiliary burning nozzle 20 can start process burner pattern according to working load or mission requirements, feed intake with in main burner 10 1 in the same way vapourizing furnace reaction chamber 40, improve the load of gasification installation, improve the continuity that vaporising fuel enters stove, improve nebulization efficiency and transformation efficiency.Can say, auxiliary burning nozzle 20 and central process burner and main burner 10 together form Alternative burner.
In addition, when main burner 10 breaks down, many burners gasification installation can not stop immediately, ensures the steady running of many burners gasification installation, avoids stopping suddenly and breakdown loss.Here, according to the needs of load, can select the process burner function of whether opening auxiliary burning nozzle 20, flexible, it is convenient to control.
It should be noted that, after the response capacity increase of vapourizing furnace reaction chamber 40, in the specifications and models without the need to improving process burner, even can also when reducing size and the load of process burner, response capacity and the load that process burner function meets vapourizing furnace reaction chamber 40 is started by auxiliary burning nozzle 20, thus extend the process burner life-span, realize the long-period stable operation of many burners gasification installation.
Such as, when constant relative to many burners gasification installation model, the model of main burner 10 can be changed little or reduce load, being balanced by auxiliary burning nozzle 20, thus the abrasion of material for process burner shower nozzle can be reduced, improving the life-span of process burner.
It is pointed out that the quantity of auxiliary burning nozzle 20 can be two, but in the present embodiment, the quantity of auxiliary burning nozzle 20 is at least three, is evenly arranged centered by main burner 10.Such as: in gasification installation top center, a process burner and main burner 10 are set, the auxiliary burning nozzle 20 of uniform more than three of top circumference.Like this, adopt multiple auxiliary burning nozzle baker together, the time of vapourizing furnace reaction chamber 40 increasing temperature and pressure when gasification installation starts can be shortened further, improve further the response capacity of gasification installation and reaction pressure.
As shown in Figure 1, the elongated central line of auxiliary burning nozzle 20 and the elongated central line of main burner 10 to intersect in vapourizing furnace reaction chamber 40 1 O on central axis.Wherein, O point is positioned at a certain position on vapourizing furnace reaction chamber 40 central axis, and the particular location of O point can carry out selected setting according to the internal diameter of vapourizing furnace reaction chamber 40 and length and ature of coal etc.Like this, the elongated central line of the Way out of many burners intersects in vapourizing furnace reaction chamber 40, and the material collision that many burners are sprayed is intersected, and contributes to the atomization of coal slurry, thus improves the atomizing effect of material, improve transformation efficiency.
As the optional embodiment of one, as shown in Figure 1, auxiliary burning nozzle 20 can be arranged at the top of vapourizing furnace reaction chamber 40, axially angle is installed formed by between the axis of auxiliary burning nozzle 20 and the central axis of vapourizing furnace reaction chamber 40---the span of shaft installation angle α can be 0 ° to 90 °, i.e. 0 ° of < α <90 °, as 30 °, 45 °, 60 ° etc.
Alternatively, as shown in Figure 2, radial direction between auxiliary burning nozzle 20 is installed angle β and be can be 360 °/N, wherein, N is the number of auxiliary burning nozzle 20, such as, for the auxiliary burning nozzle of four in Fig. 2 20, radial installation angle β is 90 °, if 3 auxiliary burning nozzles 20, then radial installation angle β is 120 °.Here to the deployment scenarios of other angles, illustrate no longer one by one.
