Description
Technical field
The present invention relates to reclaim in a kind of steam heating system the heating power pressure steam turbine of low pressure steam, relate in particular to the heating power pressure steam turbine that heating steam pressure improves in a kind of thermoelectricity plant.
Background technique
Use the enterprise of steam in the production process, ubiquity exhaust steam discharging had so not only been polluted environment but also had been wasted the energy.For exhaust steam is recycled, just exhaust steam need be improved pressure.The method that in the past improved steam pressure has mechanical compress and heating power to compress two kinds.Mechanical compress is wanted power drain, and the heating power compression directly consumes heat energy.Directly consume heat energy specific consumption electric energy economy,, reduced transition loss because reduced the transition process of heat energy to electric energy.The mode of heating power compression generally also is two kinds, the one, steam-jet ejector, another kind is to utilize steam turbine directly to drag vapour compression machine, this dual mode all is subjected to on-the-spot high pressure steam and the restriction of low pressure steam parameter, only the ratio in the voltage rise of the pressure drop of high pressure steam and low pressure steam just can have higher efficient in a certain scope, efficient is lower or make the complex structure of turbocompressor group generally speaking, cost increases, the efficient of general steam-sprayed heating power compressor is 10-20%, be up to 50%, and the efficient of turbocompressor group generally also has only 40-60%, although cogeneration power plant can be used as power with the boiler live steam and improve the pressure of extracted steam from turbine like this, satisfy hot user's usage requirement,, often can not meet the demands because of its efficient is low.
Steam-sprayed heating power is pressed the inefficient reason of steam turbine, mainly is because the high speed steam flow directly contacts mixing with the low speed steam flow, has produced due to the bigger irreversible loss; The lower reason of pressure steam turbine group efficient that turbine drags is that corresponding different optimum speeds and progression are if satisfy the requirement of efficient owing to the pressure drop of high pressure steam and the voltage rise of low pressure steam, structure is just very complicated, cost just increases, if simplified structure will be sacrificed efficient.
Summary of the invention
The present invention is directed to the problem that prior art exists, provide a kind of efficient height, high pressure steam directly not to contact, be not subjected to that high pressure steam pressure drop and low pressure steam voltage rise influence, simple in structure, piston type thermodynamic that cost is low, easy to operate is pressed vapour (gas) machine with low pressure steam.
The present invention realizes that the technological scheme of inventing is as follows: comprise two cylinders that are respectively equipped with high and low pressure steam inlet/outlet on it, place coaxial piston in the cylinder separately and the control system that is complementary with it.
Described coaxial be a kind of in d-axis, the bent axle.
Described control system comprises that the low pressure steam source links to each other with the low pressure steam import of cylinder respectively by pipeline, one-way valve, and the outlet of low pressure steam links to each other with the steam supply pipe network by one-way valve, pipeline, pressure transmitter; Source of high pressure steam links to each other with the high pressure steam import of cylinder respectively by modulating valve, the valve of the transmitter that is stressed, intelligent regulator control, and the high pressure steam outlet links to each other with the steam supply pipe network by valve, pipeline, pressure transmitter.
Described one-way valve, valve are autocontrol valve.
Described low pressure steam is imported and exported the same side that is located at piston.
Described high pressure steam is imported and exported and is located at the opposite side that piston is imported and exported with respect to low pressure steam.
The present invention compared with prior art, owing to utilize high pressure steam directly not contact with low pressure steam, employing Piston Compression mode is boosted low pressure steam with the energy of high pressure steam, two cylinder alternations make the voltage rise of low pressure steam to predetermined value, make low pressure steam outlet one-way valve open a series of technical measures such as input steam supply pipe network by control system, and the saving energy is arranged, raise the efficiency 2-4 doubly through evidence, not restricted by high pressure steam and low pressure steam parameter, Applicable scope is wide; Simultaneously simple in structure, reduce cost, be beneficial to and apply.

Fig. 2 is an another embodiment of the present invention.
Among the figure 1, cylinder; 2, piston; 3,5: the high pressure steam inlet valve; 4,6: the high pressure steam outlet valve; 7, pressure transmitter; 8, intelligent regulating valve; 9, high pressure steam inlet adjusting valve; 10,11,12,13: one-way valve.
Embodiment
Embodiments of the invention are described in detail in conjunction with the accompanying drawings.As shown in Figure 1, be respectively equipped with in two identical cylinders 1 with coaxial continuous piston 2, and cylinder 1 inner chamber is divided into low pressure steam chamber and high pressure steam chamber by piston 2, the end face in the low pressure steam chamber of cylinder 1 is provided with the low pressure steam inlet/outlet, the top in high pressure steam chamber is provided with the high pressure steam import, and the bottom is provided with the high pressure steam outlet; Described control system comprises that the low pressure steam source links to each other with the 1 low pressure steam import of two cylinders by one-way valve 10,12 respectively by valve, pipeline, source of high pressure steam links to each other with the high pressure steam import by valve 3,5 respectively by electric control valve 9, the pipeline that is controlled by AI-808C3L4L type intelligent regulator, the low pressure steam outlet links to each other with the steam supply pipe network by one-way valve 13,11, pipeline, BR571 type pressure transmitter 7 respectively, and the high pressure steam outlet links to each other with the steam supply pipe network by valve 6,4, pipeline, pressure transmitter 7 respectively; That shown in Figure 2 is the coaxial embodiment of bent axle that is of the present invention.
Low pressure steam was by one-way valve 10 when the present invention used, 12 enter the low pressure steam chamber of cylinder 1, control system instruction this moment high pressure steam inlet valve 3 is opened the high pressure steam chamber that high pressure steam then enters cylinder 1, promoting piston 2 moves right, low pressure steam pressure in the low-pressure cavity improves, one-way valve 11 is opened when boosting to the outlet rated pressure, steam enters the steam supply pipe network, valve 3 is closed when piston 2 reaches certain position before the right dead point, piston 2 reaches the dead point, valve 4,5 open simultaneously, high pressure steam in the cylinder 1 high pressure steam chamber, the right enters the steam supply pipe network from valve 4, meanwhile low pressure steam enters low-pressure cavity once more from valve 10, high pressure steam enters the hyperbaric chamber of left cylinder 1, promoting piston 2 is moved to the left, compression and low pressure steam makes it to boost when reaching the outlet rated pressure, enter the steam supply pipe network from valve 13, valve 5 is closed during certain position before reaching dead point, a piston left side, high pressure steam continues to expand, make piston 2 arrive left dead point, high pressure steam enters the steam supply pipe network from valve 6, meanwhile high pressure steam moves right from the hyperbaric chamber push piston 2 that valve 3 enters right cylinder 1, the compression and low pressure raise steam, move in circles like this, make two cylinder 1 alternations, continuously to steam supply pipe network steam supply, pressure transmitter 7 is surveyed the pressure on the steam line, and the signal that sends 4-20mA compares for intelligent regulator 8 and setup pressure value, as being higher than setup pressure value, then to make high pressure steam control valve 9 open little, then make modulating valve 9 open greatly if be lower than setup pressure value, to keep outlet pressure stable, and then the steam supply pipe network is normally moved, satisfy hot user's usage requirement.
