Description
Technical field
The present invention relates to a kind of full circulation carbonization furnace dry method to discharge of the coke system.
Background technology
At present, existing full circulation carbonization furnace adopts wet method to discharge of the coke, and the semicoke of 500 DEG C ~ 600 DEG C directly enters furnace bottom basin, and basin water level is higher than coke outlet, and its warm and humid advantage forms good sealing to gas retort bottom, prevents coal gas in stove from exposing from furnace bottom.The discharge of the coke fatal defects of technique of wet method is that semicoke water ratio is too high, the utilization of semicoke is restricted, the heat energy in its temperature-fall period is all wasted.
Summary of the invention
For overcoming above-mentioned prior art defect, the invention provides a kind of full circulation carbonization furnace dry method and to discharge of the coke system.
For achieving the above object, the technical scheme that the present invention takes is:
Full circulation carbonization furnace dry method is discharged of the coke system, preheating section top is connected with oil gas vent, and be connected with charging opening by form unloading valve I, be connected with retort section bottom preheating section, be connected with heat exchanging segment bottom retort section, heat exchanging segment top is connected with hot gas inlet, bottom is connected with cold gas inlet, heat exchanging segment inside connects set square, set square top connects shaped cap seal head, shaped cap seal head is positioned at retort section, be connected with multistage cold slag device bottom heat exchanging segment, be connected with cone pump by form unloading valve II bottom multi-stage type cold slag device.
Above-mentioned full circulation carbonization furnace dry method is discharged of the coke system, and the bottom of described multistage cold slag device is provided with water inlet, and top is provided with vapour outlet, and the comb between water inlet and vapour outlet is S type trend.
Beneficial effect of the present invention: native system structure is simple, quality is discharged of the coke in flexible operation, raising and ensure energy recovery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, full circulation carbonization furnace dry method is discharged of the coke system, preheating section 2 top is connected with oil gas vent 1, and be connected with charging opening 13 by form unloading valve I 12, be connected with retort section 4 bottom preheating section 2, be connected with heat exchanging segment 7 bottom retort section 4, heat exchanging segment 7 top is connected with hot gas inlet 5, bottom is connected with cold gas inlet 11, heat exchanging segment 7 inside connects set square 6, set square 6 top connects shaped cap seal head 3, shaped cap seal head 3 is positioned at retort section 4, be connected with multistage cold slag device 8 bottom heat exchanging segment 7, be connected with cone pump 10 by form unloading valve II 9 bottom multi-stage type cold slag device 8.The bottom of described multistage cold slag device 8 is provided with water inlet 14, and top is provided with vapour outlet 15, and the comb between water inlet 14 and vapour outlet 15 is S type trend.
Material enters preheating section 2 by charging opening 13, hot gas enters retort section 4 by material destructive distillation from hot gas inlet 5, material after destructive distillation enters heat exchanging segment 7, material after cold gas enters heat exchanging segment 7 and destructive distillation from cold gas inlet 11 carries out heat exchange makes material cool, while material cooling, cold gas temperature rises and enters retort section 4 pairs of material destructive distillation by shaped cap seal head 3, the oil gas produced is discharged by oil gas vent 1, semicoke temperature after thawing is higher, intake through the water inlet 14 of multistage cold slag device 8 and to be carried out S trend by comb the semicoke after melting is cooled, water vapour is discharged by vapour outlet 15, be connected by form unloading valve II 9 with multiple cone pump 10 and deliver to specified location bottom multistage cold slag device 8, set square 6 pairs of shaped cap seal heads 3 play a supportive role.
