Abstract
The utility model discloses an energy recovery heat electric tri-generation and tri-machine coaxial steam turbine driving unit, which comprises a steam turbine, a compressor and a generator, wherein the main shaft of the steam turbine is respectively connected with the compressor and the generator, a transmission is connected between the generator and the steam turbine, and the steam turbine adopts a steam extraction condensing turbine. The utility model is different from the common 'heating, cooling and power tri co-generation' or 'heating, power and coal gas tri-generation', exchanges the 'residual heat' and 'waste heat' generated during industrial processes through an exhaust heat boiler for generating steam with high parameter; and the steam with high parameter passes through the steam turbine and simultaneously drives an industrial compressor to work or drives the generator to generate power, the extracted steam and exhaust steam of the steam turbine are used for industrial production and life heating, realizes the step efficient utilization of energy, and has significant energy conservation and environment protection meaning.
Description
Technical field
Thermoelectric moving three combined production devices, three machines coaxial (steam turbine+compressor+generator) belong to the comprehensive utilization of the energy, and the energy-conserving and environment-protective technology has the effect that reduces pollution, environment purification, can be widely used in fields such as metallurgy, petrochemical industry, biochemical industry.The utility model is specifically related to a kind of large and medium-sized industrial enterprise and moves the coaxial steamer drive train of three coproduction, three machines with energy recovery thermoelectricity.
Background technique
Since 2006, China has strengthened energy-saving and emission-reduction work, has issued the decision of strengthening energy conservation, has formulated a series of policies and measures that promote energy-saving and emission-reduction, and large and medium-sized industrial enterprise has taked many measures and way in energy-saving and emission-reduction.But, in the technological process of a lot of large and medium-sized industrial enterprises, still exist the situation that a large amount of overbottom pressure, the waste heat energy do not have fine utilization.At present, the general pattern of the recycling of overbottom pressure, waste heat is that overbottom pressure, exhaust heat recovery power generation or overbottom pressure, heat recovery produce steam by rotating machinerys such as Steam Turbine Driven compressors, in this pattern, steam turbine is connected with compressor with generator respectively and forms two cover systems, make the energy recovery utilization ratio not high, can not realize centralized control, centralized management, unit maintenance takes high.
Along with implementing of thermoelectric moving coproduction development policies of country and energy-saving and emission-reduction work, the combination of industrial steam turbine and other prime mover is in the hope of obtaining better comprehensive benefit in the large scale system, and the thermoelectric moving three coproduction Steam Turbine Driven units of research are significant to overbottom pressure UTILIZATION OF VESIDUAL HEAT IN, energy recovery, the energy-saving and emission-reduction aspect of industrial enterprise.
Summary of the invention
At defective that exists in the above-mentioned prior art or deficiency, the purpose of this utility model is, provide a kind of energy recovery the thermoelectric moving coaxial steamer drive train of three coproduction, three machines, the utility model is different from general meaning " hot, cold, electric three alliances " or " heat, electricity, coal gas three coproduction ", but residual activity or " used heat " that produces in the industrial flow is passed through the heat exchange of waste heat (used heat) boiler, produce high parameter steam; High parameter steam drives industrial compressors acting simultaneously or drives generator for electricity generation by steam turbine, and the drawing gas of steam turbine, steam discharge is used for industrial production and the life heating, realizes that the step of the energy efficiently utilizes.
In order to achieve the above object, the utility model is by the following technical solutions:
The thermoelectric moving coaxial steamer drive train of three coproduction, three machines of a kind of energy recovery, comprise steam turbine, compressor and generator, it is characterized in that the main shaft two ends of described steam turbine connect compressor and generator respectively, are connected with speed changer between described generator and the steam turbine.
Described steam turbine adopts the condensing turbine that draws gas.
The beneficial effects of the utility model are as follows:
1, the utility model is bound up on an axle with steam turbine, compressor, generator and fastens, units layouts hot, moving, electric three coproduction have been realized, realize efficient, stable, safe heat, moving, electric three coproduction functions, reduce the operation maintenance personnel, easily realize centralized control, centralized management.
2, the utility model has been realized the maximization that waste heat (used heat) utilizes in the industrial flow.Be used in the direct Driven Compressor of steam turbine, than adopting motoring to save the double energy conversion loss of generator and motor separately, and the exhaustless power of Driven Compressor is transformed electric energy by generator, and the waste heat (used heat) of industrial process is all utilized, can significantly improve the thermal efficiency.Intermediate extraction has the most rational needs that satisfy factory steam, makes whole waste heat (used heat) utilize process to change fully.
3, the utility model net coal consumption rate is significantly less than standard, little investment, instant effect, and overall economic efficiency is remarkable.
Description of drawings
Fig. 1 is the Steam Turbine Driven set structure figure of moving three coproduction of thermoelectricity of the present invention.
Below in conjunction with embodiment's the utility model is further explained explanation.
Embodiment
Referring to Fig. 1, the thermoelectric moving coaxial steamer drive train of three coproduction, three machines of energy recovery of the present utility model, comprise steam turbine 1, compressor 2 and generator 3, the main shaft two ends of described steam turbine 1 connect compressor 2 and generator 3 respectively, are connected with speed changer 4 between described generator 3 and the steam turbine 1.
The utility model adopts the amount of drawing gas can reach 50～60% the condensation steam turbine series of completely newly drawing gas of throttle flow, can realize the multiple function of driving, heat supply, generating; Compressor can adopt centrifugal compressor or axial flow compressor according to purposes;
Working principle of the present utility model: industrial enterprise utilizes rich steam or utilizes waste material, waste gas, used heat to produce steam, condensing steam turbine 1 can be converted into mechanical energy with the interior of steam by drawing gas, the mechanical energy that transforms Driven Compressor 2 actings on the one hand, compressor 3 is used to pressurized air or other medium pressurized gass is provided in the industrial flow, residue mechanical energy drives generator 3 generatings, to electrical network output electric energy; Steam turbine has intermediate extraction on the other hand, extracts low parameter steam out and is used for heat supply or industrial process vapour.Thereby the step of realizing the energy efficiently utilizes, and the energy of whole waste heat (used heat) is all reclaimed, and utilizes more thorough.
To sum up, application of the present utility model has the important energy saving environment protection significance for large and medium-sized industrial enterprise.In addition, in the grassroot project plant design, the utility model is owing to good thermal equilibrium effect, and the system synthesis benefit is good, will be widely used.
