Definitions
- the invention is directed to a process for the discharge of slag from a water bath of a synthesis gas recovery reactor, wherein the slag is brought to a lower pressure level by means of a lock tank.
- DE 600 31 875 T2 or DE 37 14 915 A1 may be mentioned as an example, the latter corresponding to EP 0 290 087 A2 essentially.
- shut-off valves are provided in the direction of gravity below the reactor in front of the lock container as well as in the direction of gravity below the lock container to open and close here cyclically to the slag from the water bath of the reactor in the batch Transfer lock container and then later out of these.
- the known procedure has a number of disadvantages, since the cooling only in the lock container or only takes place before the lock process, so that all components of the slag / Schleussystemes including any existing slag breakers, valves, piping u. like. subject to higher loads due to the corresponding higher temperatures.
- the cooling in the lock tank or the exchange of water requires only a short time before the discharge a higher amount of time, resulting in higher cycle times.
- a disadvantage of this known process is that a higher peak cooling capacity for cooling the slag and lock hopper has to be applied, since it is in the lock vessel, as indicated above, to ensure that the temperature ⁇ 100 0 C, that a plume formation is prevented , which leads to corresponding impacts of the cooling performance for safety reasons, wherein, as already mentioned, the cooling is not continuous and the heated cooling water, which still has a temperature well below the temperature of the water bath, can not be used to cool the slag. Also, therefore, a considerable amount of make-up water is needed, since the cooling capacity can be introduced alone on this additional water in the lock container.
- the object of the present invention is that the components associated with the discharge of the slag are subjected to a low temperature, with immediate slag discharge without water exchange being made possible with minimal required cooling capacity.
- this object is achieved according to the invention in that in the outlet region of the slag from the water bath of the gas generator or the pressure vessel surrounding the slag stream a cooling water flow in a region of larger cross-section than the cross section of the inlet nozzle of another part of the plant, such as the lock container, is supplied such that a temperature stratification in the outlet area is made possible.
- cooling water flow od by means of an annular gap.
- annular gap Like. between the pressure vessel outlet and a cross-sectional taper at the lock vessel inlet.
- the invention also provides that the supply of the cooling water flow into the conveying pipe of the slag stream takes place at a low flow velocity.
- the invention provides that thedewasserström is used as a hydraulic conveying means for the slag stream for conveying the slag and against the direction of gravity to at least one lock container.
- the lock container can be placed next to the reactor. This leads to lower heights, ie there are no restrictions as regards the container dimensions in the Design of the device for discharging the slag, also several lock containers can easily be used, which process either cyclically or with partitions the corresponding slag stream.
- a particular advantage is that the strain of the carburetor can be absorbed by the eg horizontal conveyor line.
- the invention also provides that the cooling water stream is fed to the slag stream in a region of larger cross section than the cross section of the inlet nozzle of the lock container.
- the invention also provides that a portion of the recirculated cooling water flow in a lower portion of the lock container, preferably in the lower socket of the lock container, is introduced, for. to stir up finer slag particles and thus possible blockages, bridge formations od. Like. to avoid when discharging the slag, possibly also to effect a further cooling of the slag.
- part of the cooling water flow in the outlet region of the reactor or of the pressure vessel surrounding it is directed counter to the solids flow in the direction of the water bath, such that a water flow out of the water bath is avoided. This ensures that the water bath is not deprived of additional heat, the scheme so can be made that a water exchange is completely avoided.
- another embodiment of the invention consists in dividing the cooling water / slag stream into at least two lock containers and / or feeding them alternately. Due to the mutual supply to different lock containers a comparably continuous slag removal is possible, i. while a lock container is emptied, the other lock container can be filled again with slag, etc.
- the invention also provides a corresponding apparatus for carrying out the method, which is characterized in that aligned at the outlet of the reactor in the direction of gravity the slag cooling tube is provided which is provided with an annular space for gentle annular supply of a cooling water flow. This measure allows the maintenance of a temperature stratification by the gentle supply of the cooling water flow.
- the corresponding device can also be distinguished by the fact that the slag guide and cooling tube has a cross section of 0.5 to 2 m, preferably 1 m, for equalizing the delivery and flow velocities within the cooling section and associated formation of a temperature stratification.
- Fig. 1 is a simplified schematic diagram of a
- Fig. 2 in a similar representation as in Fig. 1, the design with standing next to the reactor lock containers and in
- Fig. 3 is a schematic, enlarged partial view of the pressure vessel outlet.
- Fig. 1 generally designated 1 circuit simplified a pressure vessel 2 is shown with a water bath 3, wherein the withdrawn from the water bath 3 slag crushed in a slag breaker 4 and a distributor 5 is fed to the slag, for example, alternately Lock container A and a lock container B supplies, the two lock containers are designated 6a and 6b.
- valves 7a and 7b are provided in front of the lock containers, and valves 8a and 8b are provided behind the lock containers.
- Essential for the invention is a cooling water return line, generally designated 9, which removes cooling water from the lock containers 6a and 6b via valves 10a and 10b, the cooling water flow being conducted via a pump 11 and a heat exchanger 12 and via the line section 9a eg is returned to the region of the slag breaker 4 and / or via the line section 9c before the slag breaker 4 in a line region 13a with a large cross-section.
- the optionally also hyddrauli Service promotion serving line 13 between slag crusher 4 and manifold 5 is so dimensioned that the slag stream is cooled by the supplied cooling water accordingly.
- Dashed line is another line in Fig. 1 indicated for the return of cooling water in the lower region of the pressure vessel 2.
- This line section is denoted by 9b, wherein also a further return line, designated 9c, may be provided to water in the lower region of the or to guide the lock container / s, eg in the lower nozzle of the respective lock container to possibly build up a countercurrent, the u. Aufwirbelung of mud particles u. like. can serve.
- Fig. 3 the outlet of the pressure vessel 2 is shown schematically, wherein the water bath is extended in the hopper 3 in the outlet of the pressure vessel 2 and is surrounded by an annular channel 14, in which via pipe socket 15 cooling water can be gently introduced.
- the thermal separation layer is indicated by dotted lines and denoted by 15. The approximate temperatures are given as an example in Fig. 3, without the invention being limited thereto.
