Abstract
The utility model relates to the field of residual-heat utilization of an industrial kiln and particularly relates to a power generation system using steam surplus steam. The power generation system is characterized by comprising a heat accumulator, a screw extruder and a generator which are connected in sequence, wherein a residual heat boiler is connected with the heat accumulator through a steam outlet I; and the screw extruder is connected with a heating steam pipeline through a steam outlet II. The steam outlet I is connected with a middle-pressure steam pipeline. The steam outlet II is connected with a low-pressure stream pipeline. Compared with the prior art, the power generation system has the following beneficial effects: 1) the power generation system is used for energy-saving power generation in a self-use process of decompressing and heating by using steam generated by the residual heat boiler; middle-pressure steam generates the power through the generator to realize combined heat and power generation, so that the enthalpy lost by the previous decompression valve is sufficiently utilized; 2) the occupied area of the screw extruder is small, the performance is reliable, the requirements of steam levels are low and the long-range social benefits are more outstanding; and 3) the problem of wasting energy is solved, utilization ways of three steam energies of industrial steam, steam for heating and power generation are provided, and the utilization ways can be flexible converted according to conditions.
Description
Technical field
The utility model relates to industrial furnace residual heat and utilizes the field, and the abundant pressure of particularly a kind of steam is utilized power generation system.
Background technique
At present, in industrial processes, exist the equipment of a lot of UTILIZATION OF VESIDUAL HEAT IN, like exhaust heat boiler etc.; The vapor pressure of its generation is lower and parameter is unstable, when being used for factory building heating, uses after usually directly reducing pressure into low pressure steam through reduction valve; Steam energy is wasted in throttling process, and the steam grade is descended, and a large amount of enthalpies lose in vain; The heat energy of steam is not utilized fully, causes the huge waste of the energy.
Summary of the invention
The purpose of the utility model provides the abundant pressure of a kind of steam and utilizes power generation system; Overcome the deficiency of existing technology; Be used for the steam energy-conservation generating of the personal process of decompression heating of exhaust heat boiler, medium pressure steam reduces pressure to behind the low pressure steam through generator for electricity generation; Be used for industrial plant heating, the energy is fully used.
For solving the problems of the technologies described above, the technological scheme of the utility model is:
The abundant pressure of a kind of steam is utilized power generation system, comprises that thermal accumulator is connected with screw expander, generator successively, and exhaust heat boiler links to each other with thermal accumulator through steam (vapor) outlet one, and screw expander links to each other with the steam pipe road with heating through steam (vapor) outlet two.
Said steam (vapor) outlet one connects the medium pressure steam pipeline.
Said steam (vapor) outlet two connects low pressure steam line.
Compared with prior art; The beneficial effect of the utility model is: 1) be used for the steam energy-conservation generating of the personal process of decompression heating of exhaust heat boiler; Medium pressure steam is realized cogeneration of heat and power through generator for electricity generation, makes in the past to be fully used through the enthalpy of reduction valve loss; 2) the screw expander floor space is little, and reliable performance is low to the steam grade requirement, and long-range social benefit is more outstanding; 3) solved the energy waste problem, factory steam, heating that exhaust heat boiler steam is provided are with vapour, generating three kinds of use approach, according to circumstances flexible conversion.

Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; Be that the abundant pressure of a kind of steam of the utility model is utilized power generation system example structure schematic representation; Comprise that thermal accumulator 2 is connected with screw expander 5, generator 6 successively; Exhaust heat boiler 1 links to each other with thermal accumulator 2 through steam (vapor) outlet 1, and screw expander 5 links to each other with the steam pipe road with heating through steam (vapor) outlet 28.Steam (vapor) outlet 1 connects the medium pressure steam pipeline.Steam (vapor) outlet 28 connects low pressure steam line.
Among the embodiment; The steam that exhaust heat boiler 1 produces has factory steam, heating with vapour, three kinds of use approach of generating; Flexible conversion according to circumstances; The steam that exhaust heat boiler 1 produces is divided into two-way through Medium Pressure Steam Pipeline, and one the tunnel uses with vapour as manufacture, and another road gets into thermal accumulator 2 energy-storing pressure-stabilizings;
The output of thermal accumulator 2 is further divided into two-way, and one tunnel process modulating valve 3 is delivered to screw expander 5, and screw expander 5 drives generators 6 and generates electricity, and the steam that screw expander 5 is discharged is used for heating and uses vapour; The vapour emergency bypass is used as heating in another road after 4 decompressions of reduction valve group, when screw expander 5, generator 6 maintenance, open and use.
When as the stopping using of workshop heating with vapour, running parameter that can adjusting screw rod decompressor 5, screw expander 5 is exhaust steam no longer, but discharges condensed water, thus energy saving.
