In the coal gasification course using gasification furnace, with the carbonaceous material that slurry or powder state form feed, in gasifying agent
Under effect, there is partial oxidation reaction generation high-temperature gas, the inorganic oxide in the not oxidized carbonaceous material in part and raw material
Thing forms the lime-ash of molten state, as impurity at high temperature.Impure high-temperature gas or impurity sweep along a part of high-temperature gas
Into the shock chamber of gasification furnace.Chilling ring is the critical component of shock chamber, and its effect is to be evenly distributed in Quench liquid such as water
Decline on inside pipe wall, form liquid film, with high-temperature synthesis gas be effectively isolated down-comer with lime-ash and come by this layer of liquid film, so as to protect
Down-comer is not burned, while high-temperature synthesis gas are quenched cooling to a certain extent.
Position and structure existing defects of chilling ring in the prior art, the inner ring outside of chilling ring is directly and high―temperature nuclei
Gas, lime-ash contact, cause chilling ring operating temperature too high, add lime-ash and the abrasion for causing directly is washed away to chilling ring, cause sharp
Cold ring service life is shortened dramatically.Therefore, how to adopt an effective measure and chilling ring is protected, as those skilled in the art
Problem demanding prompt solution.
The content of the invention
It is an object of the invention to overcoming the defect on existing Quench ring structure, there is provided a kind of to being radiated by high-temperature gas
Chilling ring completely cut off the device of protection.
The specific technical scheme for using of the invention is as follows：
A kind of chilling ring guard circle, the guard circle is the annular cold wall of interior logical cooling medium, is arranged on high-temperature medium life
Into between area and chilling ring, the chilling ring is the escape of interior logical cooling medium；The lower surface external diameter of the guard circle is small
The upper surface of the chilling ring is less than in the lower surface of the internal diameter of the chilling ring, and the guard circle.
According to chilling ring guard circle proposed by the present invention, wherein, the folder of cold wall and the high-temperature medium flow direction of the guard circle
Angle is less than 90 degree more than or equal to 0 °.
According to chilling ring guard circle proposed by the present invention, wherein, the cold wall is hardware.
According to chilling ring guard circle proposed by the present invention, wherein, the guard circle be the jacket structured of interior logical cooling water or
Person's coil arrangement.
According to chilling ring guard circle proposed by the present invention, wherein, when the guard circle be coil arrangement when, can also liner it is resistance to
High-temperature material.
According to chilling ring guard circle proposed by the present invention, wherein, the guard circle is the coil arrangement of interior logical cooling water, institute
Chilling ring is stated for spray structure, the lower surface of the guard circle is less than the upper surface of the chilling ring and overflowing less than spray structure
Outlet.
According to chilling ring guard circle proposed by the present invention, wherein, the guard circle is replaceable equipment.
Compared with prior art, the invention has the advantages that：
1st, thermal shock of the chilling device directly facing high-temperature medium and lime-ash is avoided, thermal stress is produced, and then damage；
2nd, guard circle of the invention is replaceable equipment, and overall cost is less than chilling device, is conveniently replaceable, and reduces cost
While shorten maintenance time.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not paid
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 Fig. 2 is referred to, two kinds of structural representations of specific embodiment of chilling ring guard circle respectively of the invention.Such as
Shown in figure, gasification furnace includes that high-temperature medium generates area 6 and the high-temperature medium cooling zone 1 positioned at the lower section of high-temperature medium generation area 6.It is high
The chilling ring 4 below cinder notch and the down-comer below chilling ring 4 are provided with warm medium cooling zone 1, are connected with chilling ring
Cooling medium 2.
Chilling ring guard circle 5 of the invention is arranged between high-temperature medium generation area 6 and chilling ring 4；The guard circle 5
Lower surface external diameter is less than the internal diameter of the chilling ring 4, so that the inwall of guard circle 5 is than chilling ring 4 closer to high-temperature medium.Institute
The upper surface of the lower surface of guard circle 5 less than the chilling ring 4 is stated, prevents from space occur between guard circle 5 and chilling ring 4 to cause
High-temperature synthesis gas understand leaking for lime-ash.And the cold wall of guard circle 5 is less than 90 more than or equal to 0 ° with the angle of high-temperature medium flow direction
Degree.Here the direction of the cold wall of guard circle 5 refers to the angle of the stringcourse of the left and right sides in the vertical section of guard circle, high-temperature medium
Flow direction is commonly referred to be vertical bottom face.In two embodiments of Fig. 1 Fig. 2 of the present invention, the vertical section of guard circle 5 is rectangle,
Its both sides stringcourse is parallel to the vertical direction, therefore the cold wall of guard circle 5 is equal to 0 ° with the angle of high-temperature medium flow direction.
The present invention provides two kinds of embodiments for the concrete structure of guard circle 5.In the embodiment 1 shown in Fig. 1, protection
Circle 5 is the coil arrangement of the jacket structured or high-temperature resistant material of inner lining (can not also serve as a contrast exotic material) of interior logical cooling water,
Its lower surface is less than the upper surface of chilling ring 4 but higher than overfall 3.In the embodiment 2 shown in Fig. 2, guard circle 5 is interior logical cold
But the coil arrangement of water, chilling ring 4 is spray structure, the lower surface of guard circle 5 less than chilling ring 4 upper surface and less than spray
Structure overfall 3.
In sum, chilling ring guard circle proposed by the present invention can avoid chilling ring directly facing high-temperature medium and ash
The thermal shock of slag, produces thermal stress, and then damage；Chilling ring guard circle of the invention is replaceable equipment, overall cost simultaneously
Less than chilling ring, it is conveniently replaceable, maintenance time is shortened while reducing cost.
