Description
Technical field
The utility model relates to a kind of power generation system, particularly relates to a kind of heat supply network backwater top pressure power generation system.
Background technique
Play April in the coming year in annual October the northern area of China, and reaching half a year is Heating Period.From factors such as environmental protection, safety and Economy, consider, by past every household, independently with coal stove for heating, progressively change heat supply network central heating into.For energy-conservation current use more be high-pressure water heating boiler heating, in an area, have exactly heating plant to adopt heat supply network piping resident's supplying high temperature hot water towards periphery, as the thermal source of heating, after use, return to again heat supply network, reheat, recycle.
Because heating plant overlay area is larger, the pressure of the high-temperature-hot-water that it provides can not be too low, otherwise be difficult to guarantee the demand of far-end heating user in region, and near-end heating user pressure of supply water is just seemed to too high, backwater after heating still has higher overbottom pressure, be flowed to heat supply network return main, the energy of this part is to have wasted in vain.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of heat supply network backwater top pressure power generation system, and it utilizes the overbottom pressure of backwater to generate electricity, and reaches energy-conservation object.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of heat supply network backwater top pressure power generation system, it is characterized in that, it comprises the first pressure transducer, the first ball valve, tee ball valve, the second ball valve, position transducer, metering valve, the second pressure transducer, the 3rd ball valve, centripetal turbine, the 4th ball valve, speed probe, asynchronous motor, the first pressure transducer is connected with the first ball valve, the second ball valve, centripetal turbine is all connected with tee ball valve, position transducer is connected with metering valve, metering valve is connected with centripetal turbine, the second pressure transducer is connected with the 3rd ball valve, the 3rd ball valve, the 4th ball valve, asynchronous motor is all connected with centripetal turbine, speed probe is connected with asynchronous motor.
Positive progressive effect of the present utility model is: the utility model heat supply network backwater top pressure power generation system utilizes the overbottom pressure of backwater to generate electricity, and reaches energy-conservation object.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model heat supply network backwater top pressure power generation system.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model heat supply network backwater top pressure power generation system comprises the first pressure transducer 1, the first ball valve 2, tee ball valve 3, the second ball valve 4, position transducer 5, metering valve 6, the second pressure transducer 7, the 3rd ball valve 8, centripetal turbine 9, the 4th ball valve 10, speed probe 11, asynchronous motor 12, the first pressure transducer 1 is connected with the first ball valve 2, the second ball valve 4, centripetal turbine 9 is all connected with tee ball valve 3, position transducer 5 is connected with metering valve 6, metering valve 6 is connected with centripetal turbine 9, the second pressure transducer 7 is connected with the 3rd ball valve 8, the 3rd ball valve 8, the 4th ball valve 10, asynchronous motor 12 is all connected with centripetal turbine 9, speed probe 11 is connected with asynchronous motor 12.The first pressure transducer 1, the first ball valve 2, tee ball valve 3, the second ball valve 4, position transducer 5, metering valve 6, the second pressure transducer 7, the 3rd ball valve 8, centripetal turbine 9, the 4th ball valve 10, speed probe 11, asynchronous motor 12 is all the element that can buy on market, such as the first pressure transducer, the second pressure transducer can adopt the sensor of red W. J. Furse & Co., Ltd, the first ball valve, the second ball valve, the 3rd ball valve, tee ball valve can adopt the ball valve of Guan Long company, centripetal turbine can adopt the centripetal turbine of Haining XingHoly whale New Energy Technology Co., Ltd., asynchronous motor can adopt the asynchronous motor of Haining XingHoly whale New Energy Technology Co., Ltd., speed probe can adopt the speed probe of development in science and technology Co., Ltd of Zhuzhou Air China.
The working principle of the utility model heat supply network backwater top pressure power generation system is as follows: the second ball valve 4 is closed, tee ball valve 3 heat supply network backwater sides are opened, electricity generating device side closure, and heat supply network backwater is directly flowed to heat supply network return main, heat supply network backwater is not sent into electricity generating device, and electricity generating device is stopped transport.The second ball valve 4 is opened, and tee ball valve 3 heat supply network backwater enter valve side closure, and valve export side is opened, and electricity generating device side is opened, and heat supply network backwater is not directly flowed to heat supply network return main, but sends into electricity generating device, and electricity generating device is in running state.When electricity generating device is in running state, backwater flows to centripetal turbine 9, and the overbottom pressure of utilizing backwater to have promotes centripetal turbine 9 rotations, and asynchronous motor 12 rotary electrifications that are directly connected with centripetal turbine 9 of drive.The pressure decreased that flows out the backwater of centripetal turbine 9, approaches heat supply network return main pressure, and is flowed to heat supply network return main.Backwater reclaims the pressure energy of backwater by this loop, reach energy-conservation object.Asynchronous motor 12 generated energy number, depend on the product that flows into the Pressure Drop that the backwater amount of centripetal turbine 9 and backwater import and export at centripetal turbine 9.With the loop in addition that centripetal turbine 9 loops are in parallel, metering valve 6 is installed on this loop.The object that this valve is set is the flow that shunting enters centripetal turbine 9 backwater amounts, thus the generated energy of adjusting centripetal turbine 9.It is to send into for Information Monitoring the use that automatic control system is implemented electricity generating device control that the first pressure transducer 1, the second pressure transducer 7, speed probe 11 and position transducer 5 etc. are also set in electricity generating device.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
