Definitions
- the invention is directed to a method for discharging the resulting in the operation of a dedusting system for raw gas dust of the type specified in the preamble of claim 1.
- the thermal gasification solid fuel such as a variety of coals, peat, hydrogenation residues, residues, waste, biomass and fly ash or a mixture of these substances is carried out under elevated pressure and high temperature with the aim of a raw gas with high energy content and / or to produce with a composition favorable for further chemical syntheses.
- the raw gas is loaded with fly ash, which has its origin in the ash content of the supplied fuel.
- the fly ash is in the form of particles that must be separated before further use and discharged from the pressure chamber.
- the usually very fine-grained solid falls as a bed, before it is discharged from the pressure chamber.
- there is gas in the void volume of the particle bed in this case raw gas which is discharged with the solids and which must be removed before further use or disposal of the ashes.
- the fly ash After separation of the fly ash from the raw gas, it is first collected over a certain period of time before this batch is discharged.
- the batch is usually transferred from the buffer in a lock container, which is still at this time at the same high pressure level.
- the lock container is then decoupled and relaxed to a lower pressure level.
- the ash in the lock container is removed for further treatment, disposal and / or storage.
- the empty lock container is brought back to system pressure by gas supply and coupled to the buffer to receive the next collected batch of fly ash.
- the purge gas must be available at a pressure level above the filter pressure, so that a short-term gas flow with a required impulse can be achieved.
- the covering of the lock container and also the cleaning of the filter elements with nitrogen are carried out, which is available to a sufficient extent from the air separation plant.
- the use of nitrogen has been proven and largely mature. If the aim of the gasification plant is the production of a synthesis gas for the subsequent performance of various chemical syntheses, then the nitrogen content in the synthesis gas is extremely undesirable and, moreover, usually limited to limits that are dependent on the respective synthesis.
- the object of the present invention is to provide a method for discharging the resulting dust in such a way that a nitrogen input into the raw gas is minimized or completely avoided in order to free subsequent chemical syntheses from the outset of a nitrogen input.
- this object is achieved according to the invention in that filter elements are positioned in the dust, which are backwashed by means of a carbon dioxide-containing gas or pure CO 2 -GaS.
- the proportion of inert gases (such as N 2 , Ar) and of hydrocarbons (such as CH 4 , C x H y ) together should be ⁇ 50%.
- the remainder consists of CO 2 and may possibly also contain synthesis gas components (CO, H 2 ) etc.
- the carbon dioxide is raised to a temperature level for backwashing, such that the required temperature is maintained at the filter elements.
- the invention provides that the CO 2 -containing backwashing gas is used for fluidizing and loosening the fly ash fill in the dust separator.
- Such fluidization or loosening may be expedient, since the mean particle diameters are very small, for example ⁇ 2 microns.
- the use of CO 2 -containing gas or pure CO 2 as a loosening gas has the advantage that only these gas components reach the raw gas. Since, according to the invention, the CO 2 -containing backwash gas is also used to cover the lock container, this component enters the raw gas while the ash passes into the lock container where it expels the portion of the gas present in the lock container, which then flows back into the raw gas.
- a further advantage of the invention is that lower volume flows are necessary for cleaning the filter elements compared to nitrogen, since smaller amounts of carbon dioxide are necessary to exercise certain pulses for cleaning the filter elements due to the higher density of the carbon dioxide , so that smaller quantities and lower compressor power will be necessary.
- supply lines which are externally heated can be used to heat the CO 2 -containing gas.
- a further embodiment of the invention consists in that the gas discharged from the lock container is fed to a dedusting device.
- Such a dedusted gas from the lock container according to the invention can be fed to an intermediate buffer and then partially used as a gas for carrying out the method steps described above, as the invention also provides.
- the adhering to the filters and purged of these dust collects in a discharge area, which is equipped with fluidizing 7 to loosen the dust for further transport, including CO 2 or CO 2 -containing gas line 6th supplied to these fluidizing devices.
- the dust is then passed via the connecting line 8 into a lock container 9, which in turn is equipped with fluidizing devices 11 in the outlet region, which are operated by means of CO 2 or by means of CO 2 -containing gas, line 10.
- the gas from the gas dome of the lock container 9 is returned by means of compensation line 12 into the gas space of the dust collector 2.
- a gas supply line 13 for CO 2 or CO 2 -containing gas is provided, which act on the backwash lines 14, the filter elements optionally impact or impulsively.
- a further line 15 is provided from the gas dome of the lock container 9, which acts on a filter element 17.
- a buffer tank 21 can be acted upon via the line 18, the gas is optionally applied via a recycle line 19 to the expansion tank 9 or derived via a line 20 as a relaxed gas according to line 22 into the environment or for further use.
- the pressing or the partial pressing of the lock container 9 can also be advantageous backwards through the filter 17 (not shown).
- the valve to the line 18 (as generally when pressed) is closed.
- Backwash gas which is used, for example, to supply 6 and 10, is used to clean the filter 17, wherein the gas then passes through the line 15 for covering the lock container.
- the discharge line for the dust is designated 16, via which the dust can be disposed of after pressure equalization.
- the pressurized crude gas containing the fly ash is fed into the filter 2. You get a Dusted synthesis gas 3 and fly ash, the latter being temporarily stored in the collecting space 5.
- the collecting space 5 is characterized by a conical shape, which opens into the connecting line 8 to the lock container 9.
- fluidizing or loosening devices 7 are provided according to the prior art, to allow the discharge of the ash in the lock container.
- the fluidizing or loosening devices 7 are operated with gaseous carbon dioxide 6.
- the collecting chamber 5 may be geometrically integrated into both the lower part of the container of the filter housing or consist of a separate constantly connected to the filter container.
- the lower part of the filter housing is also provided with fluidizing and loosening devices to assist the transport of the fly ash into the collecting space.
- fluidizing and loosening devices In the first case, in which collecting chamber and filter housing form a geometric unit, it is generally sufficient to provide fluidizing and loosening devices in the lower part in or near the conical region.
- the lock container is for this purpose at the same pressure level as the filter 2 and collecting chamber 5.
- the equalizing line 12 may also be for discharging the displaced gas to another destination, such as e.g. another container, another filter, etc.
- a dust cake builds up on the filter elements in the course of cleaning the raw gas. If this reaches a predetermined thickness, defined by the pressure loss, which increases in accordance with the filter cake layer thickness, a cleaning of the filter elements 4 by backwashing is performed.
- the filter elements 4 can be acted upon individually or in groups with a backwash gas 13, 14. This flows counter to the filter direction through the filter elements 4 and provides with a corresponding pulse for the replacement of the filter cake.
- equalization line 12 and connecting line 8 are closed and decoupled from the filter and collecting space.
- the filled lock container 9 is expanded to a lower pressure level, which is sufficient to carry out the further method steps, the expansion gas is discharged 15. A portion of the expanded gas 15 is passed through a filter 17 in a buffer tank 21 intermediate. saved. The rest of the expansion gas 20 is removed.
- At least one buffer tank 21 is particularly advantageous because it allows a portion of the gas 18 expanded from the lock 9 to be used again for partial covering 19 of the lock after emptying. As a result, the amount of gas to be discharged, consisting of carbon dioxide-containing gas and raw gas components, is reduced.
- buffer tank Another advantage of the buffer tank is equalization of the flash gas quantities.
- the classic approach of Be StrukturerentSpannung occurs at the beginning of the highest mass flow, which is smaller with decreasing tank pressure. Since, as described, inevitably small amounts of raw gas constituents are present in the gas to be expanded, the expansion gas must be supplied for proper use or disposal. In practice, this type of gas is usually supplied to combustion. Through the buffer container, it is possible to gradually equalize the amount of gas removed, which allows optimized operation of the combustion device.
- the fly ash is transferred from the lock container 9 for further handling.
- fluidizing and loosening devices 11 are located in the outlet area of the lock container 9 as well as in the collecting space 5 in order to facilitate the transfer of the fly ash.
- the loosening and fluidization takes place with carbon dioxide 10.
- With the help of the stored gas in the buffer tank 21 19 of the lock container partially covered.
- the pressing of the lock container to the required operating pressure is effected by further addition of carbon dioxide 10, for example via the fluidizing and loosening devices 11 of the lock container 9 or via additional supply devices, such as those provided for the supply of the stored gas 19.
- the further process steps to which the fly ash is subjected may be, for example, the return to the gasification process or the treatment for storage or disposal. In the latter case, care must be taken to remove the raw gas components that are inevitably still in the void volume of the fly ash.
- US 4,838,898 A and US 2007/0084117 A1 describe processes which liberate the fly ash separated from a synthesis gas in a plurality of process steps from the remaining crude gas constituents.
- the above example is selected from the range of typical operating parameters, as they occur when stringing the lock container.
- the temperature of the carbon dioxide used must be adjusted by preheating in order to compensate for the cooling effect in the throttling. This is necessary in order to be able to meet the required process temperatures and not to exceed the permissible temperature gradients, for example via the filter elements and the loosening devices.
- the carbon dioxide or carbon dioxide-containing gas used for cleaning the filter elements is preheated to the point where, after expansion to operating pressure (of the filter), it has a temperature which is above the boundary to the two-phase region.
- the carbon dioxide or the carbon dioxide-containing gas should advantageously after relaxation have a temperature which is above the condensation temperature of the raw gas components.
