Description
Technical field
The utility model relates to chemical industry equipment, specifically refers to a kind of vapourizing furnace quench chamber descending pipe operator guards.
Background technology
In coal gasification apparatus operational process, shock chamber is the key equipment of whole technique, serves the effect of synthetic gas cooling, humidification.Shock chamber is arranged on the below of vapourizing furnace combustion chamber, is connected between the two by downtake.Downtake is the vitals of shock chamber, is that synthetic gas enters the passage of shock chamber by vapourizing furnace combustion chamber, and it has with high-temperature synthesis gas and contacts very closely.
For protection downtake, usually arrange chilling ring on downtake top, the chilled water passed into by chilling ring forms water membrane at the inwall of downtake, avoids synthetic gas to contact with the direct of downtake inwall.
But, in industry park plan, the lower cinder notch inevitably stifled slag phenomenon of part of vapourizing furnace combustion chamber, when stifled slag is serious, there is bias current when causing synthetic gas to enter downtake, and due to flow velocity very large, synthetic gas can direct impact downtake inwall, can moisture film be broken through and burn downtake when gas speed is too high, bringing extreme influence to whole technical process.
Summary of the invention
Technical problem to be solved in the utility model be for the present situation of prior art provide a kind of can the not breakdown vapourizing furnace quench chamber descending pipe operator guards of available protecting downtake, thus extend the work-ing life of downtake.
The utility model solves the problems of the technologies described above adopted technical scheme: this vapourizing furnace quench chamber descending pipe operator guards, comprise the downtake be arranged in shock chamber, the entrance of described downtake connects the lower cinder notch of combustion chamber, the lime-ash outlet of the outlet shock chamber of described downtake; The top of described downtake is provided with the chilling ring connecting extraneous chilled water; It is characterized in that the periphery wall of described downtake is provided with the cooling body for cooling described downtake, the entrance of described cooling body is arranged on bottom relative to described downtake, the outlet of described cooling body is arranged on top relative to described downtake, described cooling body is communicated with external source, and described cooling body covers on the outer side wall of the downtake between shock chamber's liquid level and the outlet of described chilling ring.
Described cooling body can select as required of the prior art any one, preferably, described cooling body can be the spiral coil cooling tube along described downtake periphery wall coiled coil.
Or described cooling body can be cooling jacket, and the outlet of this cooling jacket is open upwards and is communicated with the inner chamber of described shock chamber.
Described cooling body can also for the many cooling tubulations be arranged in parallel along described downtake periphery wall.For tubulation structure, each tubulation can be parallel to the axis of downtake, also can be parallel to the contour of downtake.
In above-mentioned each scheme, described cooling body can be close to downtake outer side wall arrange, also can and outer side wall between be separated with gap; When both have gap, between described cooling body 8 and described downtake 4, the heat-transfer medium for heat conduction also can be provided with, to increase heat-transfer effect further.
Compared with prior art; the stifled slag of part is there is in vapourizing furnace quench chamber descending pipe operator guards provided by the utility model at lower cinder notch; when downtake inner side-wall chilled water protection moisture film is broken through in synthetic gas bias current; cooling body can remove the localized hyperthermia that synthetic gas bias current causes in time; strengthening cooling is implemented to downtake; avoid downtake damage so that by the serious accident of burning, effectively extend the work-ing life of downtake.

Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, this vapourizing furnace quench chamber descending pipe operator guards comprises: be arranged on the downtake 4 in shock chamber 6, and the entrance of downtake 4 connects the lower cinder notch 2 of combustion chamber 1, the lime-ash outlet of the outlet shock chamber of downtake.The top of downtake is provided with the chilling ring 3 connecting extraneous chilled water; Chilling ring entrance 7 connects extraneous Quench water source, and chilling ring outlet is positioned at the top of downtake 4 and the inner side-wall of subtend downtake, flows down along the inner side-wall of downtake to make chilled water.On the periphery wall of downtake, coiled coil has the spiral coil cooling tube 8 for cooling downtake, and this spiral coil cooling tube is the cooling body 8 of the present embodiment.
The entrance of spiral coil cooling tube 8 is communicated with external source, is arranged on bottom relative to downtake 4; The extraneous backwater equipment of outlet of spiral coil cooling tube 8, be arranged on top relative to downtake, spiral coil cooling tube 8 covers on the outer side wall of the downtake between shock chamber's liquid level and chilling ring outlet.
Spiral coil cooling tube 8 can directly fit downtake outer side wall arrange, between the two also can certain gap, interval, when being separated with gap, the heat-transfer medium (not shown) for heat conduction can be filled with between spiral coil cooling tube and the outer side wall of downtake.
