Description
Technical field
The utility model relates to the key structure in powdered coal pressuring gasified technology, specifically a kind of high-temperature synthesis gas chilling device.
Background technology
Coal Gasification Technology is one of the gordian technique of Coal Chemical Engineering Project and core technology, is the important composition of coal efficient clean utilization, and it transforms into clean crude synthesis gas by gasification.Crude synthesis gas is the main raw material of synthetic ammonia, coal liquefaction and other Chemicals of coal system.
Vapourizing furnace is the key equipment in Coal Gasification Technology, and shock chamber is one of key structure in vapourizing furnace, and its effect is mainly high-temperature synthesis gas to be lowered the temperature with slag and to realize gas slag separated.And chilling ring is the key part of Quench system, its design directly has influence on the time length of the normal operation of vapourizing furnace.
Chilling ring generally comprises the epimere part of the chilled water distribution chamber of ring-type, the chilled water transfer lime communicating with chilled water distribution chamber and downtake, forms chilled water annular space between chilled water distribution chamber and downtake.Chilled water enters chilled water distribution chamber from chilled water transfer lime, through chilled water annular space, flows out, and along downtake inner wall surface, flows down formation moisture film.
In prior art, still contain a lot of fine particle dusts and enter raw gas washing system in crude synthesis gas, can cause obstruction and the fouling of follow-up pipeline and equipment, impact is operation normally.
Utility model content
According to the technical problem of above-mentioned proposition, and provide a kind of high-temperature synthesis gas chilling device.
The technique means that the utility model adopts is as follows:
A high-temperature synthesis gas chilling device, is characterized in that:
Chilling ring I and the chilling ring II of arranging are up and down set in shock chamber, and described chilling ring I is arranged on the top of described chilling ring II;
Described chilling ring I is inner side chilling ring, comprises Quench endless tube I, Quench liquid distribution chamber I, downtake I and cooling fluid transfer lime I; Described cooling fluid transfer lime I is connected with described Quench liquid distribution chamber I, is provided with a plurality of Quench pendular ring gap rows mouthful between described Quench endless tube I and described downtake I;
Described chilling ring II is outside chilling ring, comprises Quench endless tube II, Quench liquid distribution chamber II, downtake II and cooling fluid transfer lime II; Described cooling fluid transfer lime II is connected with described Quench liquid distribution chamber II, and described Quench endless tube II is provided with a plurality of Quench liquid spray apertures.
As preferably, described Quench pendular ring gap row's mouthful diameter is 6～8mm.
As preferably, the line angle of every two described Quench liquid spray apertures medullary rays is between 15 °～30 °.Equally distributed Quench liquid spray apertures can make liquid distribution more even, and cooling performance is better.
The high temperature rough gas that feed coal produces through burning and molten ash enter gasification quench chamber from vaporizer bottom trunnion and carry out water-bath Quench.The moisture film forming between the chilled water that now chilling ring I flows out and downtake can effectively be protected downtake.Then crude synthesis gas and the fine dusts of carrying secretly rise and enter crude synthesis gas outlet pipe after water-bath washing.In uphill process, crude synthesis gas washs through the spray Quench liquid of chilling ring II, thereby further removes the fine dusts in crude synthesis gas.
Compared with prior art, compare, the utility model comprises 2 cover chilling ring devices, chilling ring I and chilling ring II are used in conjunction with, after spray washing by chilling ring II, thereby can allow crude synthesis gas be washed more fully the fine dusts further reducing in crude synthesis gas, thereby solved the excessive obstruction scale problems that causes follow-up system pipeline and equipment of ash amount in crude synthesis gas, can further to synthetic gas, carry out fast cooling in addition.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is chilling ring I structural representation of the present utility model.
