Abstract
The invention discloses a dry-type coke discharging system of a half-cycle dry distillation furnace. The upper part of a dry distillation section is connected with an oil gas outlet and also connected with a feeding inlet through a format cindervalve I; a hot cycle gas inlet is formed in the bottom of the dry distillation section; the lower part of the dry distillation section is connected with a combustion gasification section; an air inlet and a steam inlet are formed in the lower part of the combustion gasification section; the lower part of the combustion gasification section is connected with a multisection-type slag cooling device through a format cindervalve II; the lower part of the multisection-type slag cooling device is connected with a cone pump through a format cindervalve III. The dry-type coke discharging system is simple in structure and flexible to operate, and can be used for improving the coke discharging quality and guaranteeing the heat recovery.
Description
Technical field
The present invention relates to a kind of gas retort dry method that partly circulates system of the discharging of the coke.
Background technology
At present, the existing gas retort that partly circulates 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 gas retort dry method that partly circulates system of the discharging of the coke.
For achieving the above object, the technical solution used in the present invention is:
The gas retort dry method that partly the circulates system of the discharging of the coke, retort section top is connected with oil gas vent, and be connected with charging opening by form unloading valve I, the bottom of retort section is provided with thermal cycling gas entrance, retort section bottom is connected with combustion gasification section, combustion gasification pars infrasegmentalis is provided with air and steam-in, and combustion gasification pars infrasegmentalis is connected with multi-stage type cold slag device by form unloading valve II, and multi-stage type cold slag device bottom connects cone pump by form unloading valve III.
The above-mentioned gas retort dry method that partly the circulates system of the discharging of the coke, the bottom of described multi-stage type 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: the present invention 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 gas retort dry method that partly the circulates system of the discharging of the coke, retort section 3 tops are connected with oil gas vent 11, and be connected with charging opening 1 by form unloading valve I 2, the bottom of retort section 3 is provided with thermal cycling gas entrance 4, and retort section 3 bottoms are connected with combustion gasification section 5, and combustion gasification section 5 bottoms are provided with air and steam-in 10, combustion gasification section 5 bottoms are connected with multi-stage type cold slag device 7 by form unloading valve II 6, and multi-stage type cold slag device bottom connects cone pump 9 by form unloading valve III 8.The bottom of described multi-stage type cold slag device 7 is provided with water inlet 12, and top is provided with vapour outlet 13, and the comb between water inlet 12 and vapour outlet 13 is S type trend.
Material adds destructive distillation material by charging opening 1, the hot gas that the hot gas being entered by thermal cycling gas entrance 4 and the air passing into and steam produce in combustion gasification section 5, by retort section 3 by material destructive distillation, the oil gas producing is discharged by oil gas vent 11, semicoke temperature after combustion gasification is higher, water inlet 12 water inlets of multi-stage type cold slag device 7 are carried out S trend by comb the semicoke after melting are cooled, water vapour is discharged by vapour outlet 13, and cooled semicoke is finally delivered to specified location by cone pump 9.Form unloading valve II 6 has prevented that air and steam from entering multistage cold slag device 7.
