Description
Technical field
The present invention relates to heat recovery and technical field of power generation, more particularly to ORC waste-heat recovery device.
Background technique
For plant gas, biomass power generation, garbage loading embeading power plant, cement plant, steel mill etc., due to environment and raw material
Requirement, usually construction is in the suburb far from urban district, farther out apart from heat user, the flue gas of combustion engine is caused to waste or big portion
Dividing cannot be used effectively.
Traditional ORC system, using the expanding machine direct generation of electricity, working medium pump has power supply system power supply.The system flow and confession
Electric system is complicated, and grid loss is big, and up-front investment is more.Later by improving, improved ORC system is mostly used now, is expanded
Machine directly drives working medium pump, and extra power output power generation online, it is too long which will cause shaft system of unit, it is difficult to meet compact cloth
It sets.
Summary of the invention
Present invention solves the technical problem that:
The present invention provides a kind of efficient ORC machine waste heat recovery group devices, can effectively increase set structure compact, avoid axis
It is too long, the generating efficiency of raising ORC unit.
The invention adopts the following technical scheme:
A kind of efficient ORC machine waste heat recovery group device, including evaporator, condenser, working medium tank, expanding machine, supercharger；
After the high pressure gas output end of evaporator sequentially enters expanding machine, condenser, working medium tank, supercharger by pipeline, then lead to
The output end for crossing supercharger reenters evaporator；
The expanding machine and supercharger are both connected on gear shaft II, and motor is connected on gear shaft I by shaft coupling, gear shaft
II and gear shaft I pass through gear engagement connection.
The gear shaft II and gear shaft I are connected on gear-box, are connected by meshing transmission by the gear of gear-box.
The connection type of the expanding machine, supercharger and gear shaft II is end-tooth connection, taper axis connection, connecting rod company
It connects, triangle axis connection.
The motor connects external power supply.
Beneficial effects of the present invention:
(1) expanding machine, supercharger are separately mounted on gear shaft II, be can be shortened shafting, are saved arrangement, improve generating efficiency.
(2) when expanding machine is contributed, the work of supercharger 7 can be directly driven.
(3) motor is driven by gear shaft I, gear shaft II, can effectively adjust the revolving speed of gear shaft II, is realized swollen
The efficient design of swollen machine, supercharger.
(4) compact-sized, by gear-box, realize the integrated of unit.Relative to conventional design, which can be effective
The problems such as conventional arrangement bring shafting is too long, and whole system land occupation is excessive, and arrangement is inconvenient is reduced, the whole effect of unit is improved
Rate.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
The present invention provides a kind of efficient ORC(Organic Rankine Cycle) machine waste heat recovery group device, which is existing system
System, the present invention improve its connection structure, which includes booster expansion turbine group, evaporator, condenser, control system
System.The booster expansion turbine group uses multiaxis arrangement, configures synchronous motor, the high pressure gas that evaporator generates is through swollen
It drives booster stage to do work after swollen grade expansion work, is condensed out liquid working substance for condenser and pressurizes.
In embodiment as shown in Figure 1, including evaporator 1, condenser 2, working medium tank 8, expanding machine 3, supercharger 7.
Wherein, the working medium being heated in evaporator 1 enters expanding machine 3 by pipeline, makes 3 expansion work of expanding machine, swollen
The medium that swollen machine 3 exports enters condenser 2 by pipeline and is condensed, and condensed medium is entered in working medium tank 8 and carried out
It stores, the medium in working medium tank 8 can enter supercharger 7 and work, and the medium exported after the work of supercharger 7 re-enter into steaming
It works in hair device 1, again output high-pressure gas.
In above-mentioned device, expanding machine 3 and supercharger 7 are both connected on gear shaft II 6, and motor 4 is connected by shaft coupling
On gear shaft I 5.Gear shaft II 6 and gear shaft I 5 are attached on gear-box 9, are connected by the gear engaged transmission of gear-box 9
It connects.
When above-mentioned motor 4 is driven by gear shaft II 6 and gear shaft I 5, and since motor is connected to gear shaft I 5
On, the revolving speed of gear shaft II 6 can be effectively adjusted by motor, and then realize the efficient design of expanding machine 3, supercharger 7.
In the present invention, expanding machine 3, supercharger 7 are both connected on gear shaft II 6, when expanding machine 3 is in the effect of high pressure gas
When lower work is contributed, the work of supercharger 7 can be directly driven by gear shaft II 6, and compared with existing connection type, it can
Shorten shafting, saving arrangement from significant, improves generating efficiency.
Above-mentioned expanding machine 3, supercharger 7 and the connection type of gear shaft II 6 be end-tooth connect, taper axis connection, company
Bar connection, triangle axis connection.
Motor 4 can connect external power supply, be powered by external power supply.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without depart from that overall concept of the invention, several changes and improvements can also be made, these also should be considered as of the invention
Protection scope.
