Description
Technical field
The present invention relates to a kind of full circulation carbonization furnace dry method system of the discharging of the coke.
Background technology
At present, existing full circulation carbonization furnace adopts wet method to discharge of the coke, and the semicoke of 500 ℃～600 ℃ directly enters furnace bottom basin, and basin water level is higher than coke outlet, and its warm and humid advantage is that gas retort bottom is formed to good sealing, prevents that in stove, coal gas exposes from furnace bottom.The discharge of the coke fatal shortcoming of technique of wet method is that semicoke water ratio is too high, and the utilization of semicoke is restricted, and 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 system of the discharging of the coke.
For achieving the above object, the technical scheme that the present invention takes is:
The full circulation carbonization furnace dry method system of the discharging of the coke, preheating section top is connected with oil gas vent, and be connected with charging opening by form unloading valve I, preheating section bottom is connected with retort section, retort section bottom is connected with heat exchanging segment, Yu Re gas inlet, heat exchanging segment top is connected, Yu Leng gas inlet, bottom is connected, the inner set square that connects of heat exchanging segment, set square top connects shaped cap seal head, shaped cap seal head is positioned at retort section, heat exchanging segment bottom is connected with multistage cold slag device, and multi-stage type cold slag device bottom is connected with cone pump by form unloading valve II.
The above-mentioned full circulation carbonization furnace dry method system of the discharging of the coke, 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 is simple in structure, flexible operation, raising discharge of the coke quality and guarantee energy recovery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the full circulation carbonization furnace dry method system of the discharging of the coke, preheating section 2 tops are connected with oil gas vent 1, and be connected with charging opening 13 by form unloading valve I 12, preheating section 2 bottoms are connected with retort section 4, retort section 4 bottoms are connected with heat exchanging segment 7, heat exchanging segment 7 Yu Re gas inlets, top 5 are connected, Yu Leng gas inlet, bottom 11 is connected, the inner set square 6 that connects of heat exchanging segment 7, set square 6 tops connect shaped cap seal head 3, shaped cap seal head 3 is positioned at retort section 4, heat exchanging segment 7 bottoms are connected with multistage cold slag device 8, multi-stage type cold slag device 8 bottoms are connected with cone pump 10 by form unloading valve II 9.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, the material of cold gas from cold gas inlet 11 enters heat exchanging segment 7 and destructive distillation carries out heat exchange makes material cooling, in the time of material cooling, cold gas temperature rises and enters 4 pairs of material destructive distillation of retort section by shaped cap seal head 3, the oil gas producing is discharged by oil gas vent 1, semicoke temperature after thawing is higher, through water inlet 14 water inlets of multistage cold slag device 8, by comb, carrying out S trend cools to the semicoke after melting, water vapour is discharged by vapour outlet 15, multistage cold slag device 8 bottoms are connected and deliver to specified location with a plurality of cone pumps 10 by form unloading valve II 9, 6 pairs of shaped cap seal heads 3 of set square play a supportive role.
