Abstract
The utility model relate to a kind of there is thermo-lag drippage edge slag bank fluid, namely for original for the gasification of heat gas and molten slag are transferred to slag bank fluid for directly carrying out the quench chamber that cools, wherein in order to the drippage of described molten slag constructs thermo-lag drippage edge from the vaporizer of entrained flow gasifiers.Described drippage along preventing molten slag because backflow, the quenched water of cold air that water vapor is saturated and spray and just harden before entering into quench chamber and cause blocking.
Description
Technical field
The present invention relates to a kind of for when to when carrying out partial oxidation containing the liquid fuel of ash or the solid fuel of dirt shape preferably in supercharging the gasification gas of the slag of liquid state and heat transferred to device the quench chamber of entrained flow gasification reactor from vaporizer.
Background technology
The present invention is not only suitable for reactor that vaporizer surrounds by cooling cowl but also is suitable for the reactor that those vaporizers are limited by fire-resistant furnace lining, shown in patent documentation DE4446803 and EP0677567.
At this, according to the different system introduced in this art, the slag of original gas and melting is discharged from the vaporizer of equipment for gasification dividually or jointly, as shown in DE14718131.At J.Carl, " Noell-Konversationsverfahren (Noel's transformation approach) " of P. Fritz, EF press, " Die Veredelung und Umwandlung von Kohle (refining of coal and conversion) " DGMK of 1996 and M.Schingnitz, can find the detailed description to whole technology in " GSP-Verfahren(GSP method) " this chapter in December, 2008.From vaporizer, discharge the original gas of gasification and molten slag be uninterruptedly not only prerequisite that continuously carrying out gasifies runs but also the output determining granular slag, thin slag and thin dirt, wherein the latter needs to expend a lot of time and efforts and cleans.
Document DD299893 show a kind of for by original for the gasification of heat gas and molten slag from the vaporizer of entrained flow gasifiers be discharged to subsequently, be used for cooling gas and be used for the device the fast cooling device of granulated slag.This device is made up of the cover of water cooling tube, and the bottom of described water cooling tube is surrounded by drowning pipe, and described drowning pipe is damaged by the protected medium be not heated of moisture film on inner side.Described drowning pipe passes into the pond for the original gas of cooling heat and slag and its granulation.The interference caused by the slag deposition thing in drowning pipe is shown as disadvantageous, and these slag deposition things do not allow the moisture film of homogeneous to enter.The water carried by spray has prevented slag constantly to drip along on limit at the lower of dropping body, can form obstruct thus.
Document DD288614 shows a kind of device, and wherein the vaporizer of entrained flow gasifiers and outdoor fast cooling device (Freiraumquenchung) couple together by slag bank fluid.This outdoor fast cooling device is not by the quenched water accessory that sprayed into by single-stage or multistage nozzle ring of water coolant in other words.Here also exist following dangerous, i.e. bank fluid lower is sprayed water moistening along limit, this equally also causes forming the slag deposition thing solidified.Even if when selecting resistant to elevated temperatures material, the change programme had without the thermal protection system of cooling also only demonstrates insufficient stability because temperature is very high.
Summary of the invention
From prior art, task of the present invention realizes a kind of device, its allow heat the original gas of gasification and molten slag from the vaporizer of entrained flow gasifiers reliably transfer to subsequently, for the quench chamber by spraying into the direct cooling heat medium of moisture.The temperature up to 1900 DEG C and the pressure up to 10MPa can be there is at this.
This task is solved by the device with feature described in Section 1 claim, and wherein dependent claims specifies the favourable embodiment for solving proposed task.
By arranging that thermo-lag drippage is along preventing in slag excretion body, even if still arrive drippage edge from the quenched water spraying into nozzle under the interference of uniform atomizing and therefore may cause slag deposition, described slag deposition can hinder slag to discharge equably.Namely prevent molten slag because adverse current, the quenched water of cold air that water vapor is saturated and spray and just harden before entering into quench chamber and cause blocking.
