Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail.
Referring to Fig. 1 to Fig. 4, a kind of high temperature dry ash cooler, comprises cools body 1, and described cools body 1 is provided with punishment in advanceChamber 11 and the cooling chamber 12 that is arranged at 11 outsides, punishment in advance chamber, be provided with feed mechanism 2 in described punishment in advance chamber 11; Described punishment in advance chamber 11One end be provided with charging aperture 13, the other end of described punishment in advance chamber 11 is provided with discharging opening 14; Establish one end of described cooling chamber 12Be equipped with the first water inlet 15, the other end of described cooling chamber 12 is provided with the first delivery port 16; Also comprise for driving feederThe drive unit 3 of structure 2. High temperature dry ash mentioned herein refers to the various slags of the fuel generation after burning that comprises high temperature furnaceAnd ashes etc., the operation principle of this cooler is: preferably this cooler is directly installed on to the slag-drip opening of high temperature furnace, this sample prescriptionJust directly cooling, high temperature dry ash enters punishment in advance chamber 11 from charging aperture 13, meanwhile, in cooling chamber 12, passes into cooling water, this cooling waterEnter from the first water inlet 15 of cooling chamber 12, discharge from the first delivery port 16, realize continuous-flow, thereby to punishment in advance chamber 11 shapesBecome constant cooling, certainly, also can regulate by control valve the flow velocity of cooling water, thereby improve cooling velocity; High temperature dry ash existsUnder the effect of feed mechanism 2, constantly forward and be cooled to gradually predetermined temperature, then discharge from discharging opening 14, like thisCooled high temperature dry ash can directly be concentrated stacking, need not share heat radiation, save land used, and this cooler is being realized high temperatureWhen cooling, cooling water can also be carried out to energy recovery, namely the water by cooling chamber 12 be carried out to energy recovery, adopt pipeRoad is delivered to hot water in productive life and is recycled, thereby has avoided the waste of heat energy, and this cooler operating efficiency is high, coolingSpeed is fast, saving human cost that can be a large amount of.
The experiment proved that: this cooler generally reaches 1000 ~ 1100 degrees Celsius in the temperature of the high temperature dry ash of charging aperture 13, warpAfter this cooler is cooling, detect at discharging opening 14 that the temperature of dry ash is minimum reaches 50 degrees Celsius, good cooling results.
In the technical program, described feed mechanism 2 comprises transmission shaft 21 and is arranged at the helical-blade on transmission shaft 21 surfacesSheet 22. When feed mechanism 2 is worked, transmission shaft 21 rotarily drives helical blade 22, makes helical blade 22 that material is pushed to dischargingMouth 14 directions, the stroke of its transmission is long, thereby improves cooling effect.
Specifically, described helical blade 22 comprises the continous way helical blade 221 and the distributing helical-blade that set graduallySheet 222, described continous way helical blade 221 is positioned at the feed end of punishment in advance chamber 11. Described continous way helical blade 221 can will enterThe dry ash of material mouth 13 is sent in punishment in advance chamber 11 fast, adopts continous way helical blade 221, and its feeding efficiency is high, has avoidedMaterial mouthful 13 slag charges are piled up, and described distributing helical blade 222 is because blade quantity is many and disperse this distributing helical blade222 can carry out fragmentation to the slag charge of larger volume, thereby improve cooling speed, certainly, and described distributing helical blade 222Certain cutting edge is preferably set, in the time of fragmentation, can improves broken effect.
Because transmission shaft 21 is in the time working, need to contact with high temperature dry ash the thickness for fear of high temperature to transmission shaft 21Impact, in the technical program, described transmission shaft 21 comprises successively the first connecting axle 211 of connecting, quill shaft 212 and theTwo connecting axles 213, described the second connecting axle 213 is provided with passage 214, and described passage 214 communicates with the inside of quill shaft 212.Utilize this passage 214 to carry out transmission shaft 21 further cooling, as air-cooled, water-cooled etc.
