Definitions
- the invention is directed to a method for removing in particular in the syngas recovery obtained slags from a slag bath located in a pressure vessel in a sump for the slag, in the direction of gravity below the slag bath, below the slag if necessary, a device for breaking the slag and a lock valve is provided between the containers, as well as a system for carrying out this method.
- this object is achieved according to the invention in that a standing in contact with the liquid in the containers, filled with a gas bubble space, in particular an annulus or a separate container, is provided in which the pressure of Gas bubble is controlled by gas supply such that at least a portion of the water in the slag locks / plenum when opening the upper slag bath lock valve flows through this in the direction of the slag bath against the direction of gravity.
- the granules of the slag forming container temperatures in the saturation region for example at 200 0 C, which lead at the end of the system with low cooling to a significant vapor formation, which, as stated above, to avoid.
- the invention provides in an embodiment that following the constriction a narrowed flow channel, in which the slag / water stream is cooled, is provided and / or that generates a countercurrent to the slag stream in the slag collecting / lock container by feeding colder water becomes.
- a tangential or secant feed of the water to create swirl and to improve the cooling.
- a particularly favorable procedure, in particular at the end of the slag treatment path, is that the emptying of the slag collecting / lock container by supplying the fresh water adjusted the temperature and opened after reaching the desired temperature, an outlet valve and the water / slag mixture of an encapsulated Absetzpfanne od. Like. is supplied, wherein the encapsulated Absetzpfanne equipped with means for discharging the settled slag and with facilities for the withdrawal of vapors.
- this gas bubble 5a is in operative contact with the liquid clearance in the separation vessel 5, wherein the gas pressure via the line 23 is adjustable so that there is such an overpressure that when opening the lock 4 to a jerky short-term backflow of the liquid mixture from the separation vessel 5 passes through the valve 4 into the funnel region 3 of the slag bath 1, in order to solve any slag bridges wedged thereon.
- the separating tank 5 is followed by a narrowed flow channel 7, which is then fed to a slag / sluice collecting space 8, at the end of which an outlet valve 9 for discharging the slag accumulating there is located.
- the flow channel 7 and the container 8 may be equipped with external cooling coils to significantly cool the flowing slag / water stream
- a supply of cold water to this lock container 8 may be provided, which is designated in Fig. 1 with 20, wherein a cooling, circulating flow is adjustable.
- a corresponding flow line is designated in Fig. 1 with 21, which may be connected to the line 20 via a not shown here Slag / water treatment may be connected to form a Ringströrnung.
- the discharge valve 9 leads to an encapsulation designated 10 of a slag receiving pan 13, which is filled with slag discharge means, e.g. a scraper conveyor 13a, may be equipped, wherein the Schlakkeaustrag called 12 is additionally acted upon by a spray device 11 with liquid to prevent the discharge of impurities to the environment.
- slag discharge means e.g. a scraper conveyor 13a
- a vapor withdrawal 15 is provided, which opens into a drift eliminator 16, with 17 a delivery device, e.g. a water jet pump is indicated, which can be operated simultaneously with a further spray 18, to spray the incoming slag, which then settles in the pan, which is designated 14.
- the exhaust air outlet from the demister 16 is designated 19.
- the water jet pump 17 and the spray device 18 require a high water flow, which is similar to the slag water flow from the container 8 during emptying through the valve 9, eg 12 m 3 in two minutes, ie 0.1 m 3 / s ,
- water from a pressure reservoir 27 for the water jet pump 17 and the spray device 18 and optionally also for the flushing 20 during the filling of the container 8 with Slag used.
- the overpressure is generated with a pressure pad. Preference is given to a higher pressure than that of the water bath, so that the water first for the rinse 20 under high pressure and can then be used for the water jet pump 17 and the spray device 18 during the emptying of the container. Also for the filling of the empty container 8 in the pressureless state, a similarly high water flow is required. This water requirement can be covered by an inexpensive, non-pressurized reservoir, which can be housed above the container 8 (not shown) in order to be able to transfer the water only with the help of the hydrostatic pressure. Both containers are supplied with water with a relatively small flow of water during the entire cycle, for example one hour. The reservoirs also allow the use of continuously accumulated or treated and cooled process water.
- Fig. 1 also shows the means for forming a slag flow supporting ring flow with extract of the liquid from the separation vessel 5 via a circulation pump 22 in the slag bath container 1 below the liquid level.
- a line for the return of displaced water is indicated, with 25 a possible derivation of the displaced water depending on the feed of fresh water, e.g. via the line 20, wherein with 26 an exhaust duct is indicated.
- FIG. 2 a slightly modified embodiment of the system is shown, wherein the elements are the same effective wear the same reference numerals as in Fig. 1, but there is the separation vessel 5 with internals 6 and the slag / lock collection chamber 8 formed as a component and in Fig. 2 denoted by 5, 8.
- FIG. 2 also shows a few additional parts of the installation, for example a fresh water storage tank 27, which is equipped with a gas buffer 28, as well as a slag / water treatment plant, generally designated 29, which contains slag from the individual system parts. Water can be supplied, this if necessary via a line 30 as filtrate the slag bath container 1 can be fed again.
- the described embodiments of the invention are still to be modified in many ways, without departing from the spirit.
- the invention is not limited in particular to a specific shape of the individual components, not even in the manner of a slag breaker 2, the particular way of cooling the cooling section 7 and the treatment of the slag water, to name just a few examples.
- only one lock is provided, e.g. for comparably low slag throughput (e.g., 10 t / h).
- slag throughput e.g., 40 t / h
- two parallel locks with all components i. be provided from the valve 4 to the valve 9 in duplicate.
