Description
Technical field
The utility model relates to a kind of afterheat generating system, relates in particular to a kind of electricity generation system of utilizing coke dry quenching furnace cogeneration.
Background technology
Dry coke quenching for coke wet quenching, dry coke quenching be adopt inert gas by red Jiao at the cooling a kind of coke quenching method of the environment borehole cooling of anaerobic.In dry coke quenching process, red Jiao packs into from dry top of putting out stove, and low temperature inert gas blasts dry putting out in the red burnt layer of stove cooling section by circulating fan, and cooled coke is discharged from the dry furnace bottom that puts out; Absorb temperature raises after red burnt latent heat inertia recyclegas from coke dry quenching furnace ring-shaped flue is discharged, enter dry coke quenching residual heat boiler and carry out heat exchange, the steam that boiler produces enters steam turbine and drives generator generating, enters circulating fan again blast the dry stove that puts out from the cooled low temperature inert gas of dry coke quenching residual heat boiler.
Current coke wet quenching stove waste heat power generation system, waste gas and the dust of generation are serious to atmosphere pollution, are unfavorable for environmental protection; Though existing dry coke quenching afterheat generating system has reduced waste gas and dust discharge amount, has reduced air pollution, utilization rate of waste heat is low, complex structure, construction cost are high, and security performance is lower.
Utility model content

Steam Turbine is connected with generating set;
On storage heater, be provided with pressure gauge; On described coke dry quenching furnace, be provided with carbon monoxide detector.
The utility model has been simplified system architecture, has reduced construction cost, is provided with storage heater simultaneously, has improved UTILIZATION OF VESIDUAL HEAT IN efficiency, has improved the security of operation, energy-saving and environmental protection more.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is that system of the present utility model forms structural representation.
In figure: 1, inert gas entrance; 2, carbon monoxide detector; 3, coke dry quenching furnace; 4, high temperature inert gas outlet; 5, dry coke quenching residual heat boiler; 6, pressure gauge; 7, Steam Turbine; 8, generating set; 9, storage heater; 10, inert gas recovery tube; 11, cooling chamber; 12, valve.
The specific embodiment
As shown in Figure 1, the utility model comprises inert gas entrance 1, carbon monoxide detector 2, coke dry quenching furnace 3, high temperature inert gas outlet 4, dry coke quenching residual heat boiler 5, pressure gauge 6, Steam Turbine 7, generating set 8, storage heater 9, inert gas recovery tube 10, cooling chamber 11 and valve 12.
Dry coke quenching residual heat boiler 5 is connected with coke dry quenching furnace 3 by pipeline one end, and the other end is connected with storage heater 9; Dry coke quenching residual heat boiler 5 is connected with cooling chamber 11 by inert gas recovery tube 10, and cooling chamber 11 is connected on inert gas entrance pipe by inert gas recovery tube 10.Storage heater 9 is connected by respectively with one group, valve, two or more sets Steam Turbine 7.Steam Turbine 7 is connected with generating set 8.
On storage heater 9, be provided with pressure gauge 6.On coke dry quenching furnace 3, be provided with carbon monoxide detector 2.The setting of pressure gauge 6 and carbon monoxide detector 2, makes the utility model can constantly recognize the pressure of system and the content of carbon monoxide in use, to reasonably discharge and prevent, has improved the security performance of system.
Electricity generating principle: low temperature inert gas enters the red burnt latent heat of coke dry quenching furnace absorption and becomes high temperature inert gas, and enter dry coke quenching residual heat boiler heat is passed to water, make water become steam, steam successively enters the last Steam Turbine that arrive such as storage heater (playing the effect of storage or accumulation of energy) and drives generator generating.On coke dry quenching furnace, be provided with carbon monoxide detector, prevent explosion danger.It is cooling that inert gas enters cooling chamber through piping 10, finally enters coke dry quenching furnace and re-use (fully having accomplished energy-conserving and environment-protective).What in figure, arrow represented is the route that UTILIZATION OF VESIDUAL HEAT IN and inert gas reclaim.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
