Description

Novel chilling chamber

Technical Field

The utility model relates to the technical field of coal gasification, in particular to a novel chilling chamber.

Background

The gasifier is a device for converting solid or liquid fuel into gas fuel, and is widely applied to the fields of chemical industry, metallurgy, energy sources and the like. In the gasification furnace, the chilling chamber is an important component part and mainly comprises a chilling ring, a descending pipe, a shell and the like, wherein the chilling ring is arranged at the upper part of the descending pipe, chilling water is uniformly distributed through the chilling ring, a layer of water film is formed on the inner surface of the descending pipe to flow down, so that the descending pipe is prevented from being damaged by high-temperature gas and slag, and the effect of protecting the descending pipe from deformation caused by high temperature is achieved.

Because the existing chilling ring is mostly in direct contact with high-temperature synthetic gas and slag, the chilling ring can be subjected to high-temperature overheat deformation, so that an annular gap in the chilling ring is deformed, and uneven chilling water distribution can not well reduce heat for a downcomer. The internal structure of the annular space of the existing chilling ring is not improved, and most of chilling water flowing out through the water outlet of the annular space flows into the bottom of the shell vertically along the inner wall of the descending tube, so that when the chilling ring is slightly deformed, uneven water film distribution of the descending tube can possibly cause the burning-through of the chilling ring.

Meanwhile, the prior down tube mostly welds the pipe orifice on the shell directly, and the welding contact area of the pipe orifice and the shell is small, so that the down tube falls off from the shell under the scouring of high-temperature slag.

Such as the chinese patent with the document number CN206858506U, which discloses a split type gasifier quench chamber, the patent greatly simplifies the internal structure of the quench chamber and reduces the manufacturing and installation difficulties of the quench chamber. However, as one end of the cooling chamber down tube 3 is welded and fixed at the cooling chamber inlet 7, the down tube is easy to fall off from the shell under the scouring of high-temperature slag; at the same time, the patent does not improve the inside of the water jacket 8 (equivalent to a quench ring), which makes the quench water flowing out from the gap between the bottom edge of the water jacket 8 and the inner wall of the downcomer 3 slide down vertically along the inner wall of the downcomer, and when the inner water jacket 8 provided in the downcomer 3 is deformed by heat, the quench water flowing out from the gap cannot necessarily be uniformly distributed on the inner wall of the downcomer, which may cause the downcomer to burn out.

The down tube 3 is arranged in the shell 1 through a rib plate 13, one end of the down tube 3 is embedded in the jacket end socket 3, an inner annular gap and an outer annular gap are formed in the jacket end socket 3, and the inner annular gap and the outer annular gap are communicated. The foam breaker 4 and the partition plate 14 are welded or connected between the inner wall of the shell 1 and the outer wall of the downcomer 3 through angle steel, the partition plate 14 is an annular steel plate and mainly plays a role of isolating a shell cavity, the partition plate 14 is positioned above the foam breaker 4, the air outlet 7 and the water inlet 6 are positioned below the partition plate 14, the water inlet 6 is connected with a water inlet pipe 17 in the shell, and the water inlet pipe 17 penetrates through the partition plate 14 in a sealing manner; the water outlet 8 is positioned below the water inlet 6.

Because the middle of the jacket end socket is hollow, two ports of the down tube 3 are in a zigzag shape, thus high-temperature synthesis gas and slag flow into the down tube through the jacket end socket, the zigzag design is favorable for breaking the boundary layer formed when the slag flows in the pipeline, thereby reducing the flow resistance, improving the flow efficiency, and the zigzag design of the lower port of the down tube 3 is favorable for eliminating bubbles.

In some embodiments, the inner annular space is uniformly circumferentially provided with swirl vanes 21; the outer annular gap is uniformly circumferentially provided with positioning claws 22.

In some embodiments, the bubble breaker 4 is an annular bubble breaker plate having three layers, the three layers of annular bubble breaker plates being horizontally or obliquely distributed in parallel between the inner wall of the housing and the outer wall of the downcomer. As shown in fig. 3-5, the annular bubble breaking plate comprises angle steel uniformly welded in a metal ring. Of course, the annular foam breaking plate can also be a commercially available annular foam breaking plate.

In some embodiments, the outer wall of the down tube 2 is welded with a stiffener 5 or stiffening tube.

The novel chilling chamber can pass through the lug type support 16 to fixedly install the whole chilling chamber shell 1, and after the shell 1 is fixed, the combustion chamber can be hoisted on the corresponding combustion chamber bolt hole and fixed. And then the water inlet 6, the air outlet 7 and the water outlet 8 are connected with corresponding procedures.

When the gasification furnace works, the coal water slurry firstly carries out combustion reaction in the combustion chamber of the gasification furnace, a large amount of synthesis gas and melted ash slag generated after combustion flow into the chilling chamber from the combustion chamber, sequentially pass through the jacket end socket 2 and the down tube 3 of the chilling chamber, finally cool and wash at the bottom of the chilling chamber shell 1, and the ash slag sinks into the slag hole 11 after washing water bath in the chilling chamber. The synthetic gas continuously bubbles in the water bath, and bubbles with the synthetic gas rise, and after three-stage defoaming by the foam breaker 4, the synthetic gas is discharged out of the chilling chamber through the air outlet 7 to enter the next working procedure. When a large foam is observed in the quench chamber by the level gauge, an antifoaming agent may be added to the quench chamber through the dosing port 9. In order to maintain the constant liquid level of slag water at the bottom of the shell 1 when the gasification furnace works, the water inflow from the water inlet 6 and the water outflow from the water outlet 8 can be controlled to be consistent.

It should be noted that when the synthetic gas and the melted ash slag flow from the combustion chamber to the quench chamber, the quench water needs to be introduced into the inner wall of the downcomer 3 in real time, so that a water film is formed on the inner wall of the downcomer 3 to protect the downcomer 3 from being burnt. The chilling water specifically sequentially enters the descending tube 3 through the water inlet 6, the water inlet pipe 17, the outer annular gap and the inner annular gap of the jacket seal head 2, and the annular gap in the descending tube 3 is provided with the swirl vanes 21, so that the chilling water forms annular tangential flow on the descending tube 3, and the water film thickness of the descending tube is greatly increased.

When the gasification furnace works, ash is removed by an end cover or an ash locking valve on the opened slag hole 11, and other substances such as ash can be removed by opening the hand hole 10 when the gasification furnace is stopped if necessary.

It should be noted that, in the actual operation of the quench chamber, the next connection procedure of the water inlet 6, the water outlet 8 and the air outlet 7 is not fixed, so long as the principle and the purpose of the present utility model can be achieved, and whether the water inlet 6, the water outlet 8 and the air outlet 7 are provided with valves is also not fixed, and whether the valves are provided should belong to the protection scope of the present utility model. Secondly, the observation sequence and the effect of the liquid level meter and the pressure meter 15 can be adjusted according to the actual working condition, for example, the pressure meter 15 can be replaced by other measuring meters, for example: expansion type thermometers, pressure type thermometers, flow meters, and the like.
