This structure is less than the prior art in one group of heat source 1 supply. The heat source 1 is boiler equipment, the boiler equipment operates with large temperature difference, the output of the boiler is fully utilized, and the heat supply capacity of the main circulating pipe is increased. The number of running boiler equipment is reduced, and the electricity consumption of the circulating pump and the burner 2 is reduced, so that the energy consumption is saved.
In the present application, a circulation assembly is connected between the first oil outlet pipe 12 and the second oil inlet pipe 13, which is different from the original technical scheme. The heat utilization equipment operates by adopting small temperature difference through the circulating assembly, so that the heat supply stability is improved, and the qualification rate of the produced products is ensured.
The circulation assembly includes a third oil inlet pipe 23, a third oil inlet valve 24, a fourth oil inlet pipe 25, a fourth oil inlet valve 26, a fifth oil inlet pipe 27, a fifth oil inlet valve 28, a second circulation pump 29, a third oil outlet pipe 30, and a third oil outlet valve 31.
The third oil inlet pipe 23 is connected with a third oil inlet valve 24, one end of the third oil inlet pipe 23 is connected to the first oil outlet pipe 12, the fourth oil inlet pipe 25 is connected with a fourth oil inlet valve 26, one end of the fourth oil inlet pipe 25 is connected to the oil supply main pipe 8, the other ends of the third oil inlet pipe 23 and the fourth oil inlet pipe 25 are connected with one end of a fifth oil inlet pipe 27, the fifth oil inlet pipe 27 is connected with a fifth oil inlet valve 28, the other end of the fifth oil inlet pipe 27 is connected with the input end of a second circulating pump 29, and the output end of the second circulating pump 29 is connected to the second oil inlet pipe 13 through a third oil outlet pipe 30 connected with a third oil outlet valve 31.
The power of the second circulating pump 29 is smaller than that of the first circulating pump 5, a frequency converter is arranged on the second circulating pump 29, the lift and flow of the second circulating pump 29 can be adjusted in real time through the frequency converter, and the supplementing amount of high-temperature heat conduction oil can be adjusted in real time through the fourth oil inlet valve 26, so that the heating amount meets the normal use of the second heat utilization equipment 4. The second circulation pump 29 is made to lift just against the own resistance of the second heat-consuming device 4. Thus, the heat utilization stability of the second heat utilization device 4 is improved, the flow and the lift of the second circulating pump 29 are reduced, the power of the second circulating pump 29 is reduced, and the electricity consumption is saved.
In the prior art, the number of heat sources 1 is set to 2 (of course, 3, 4, 5, etc.), the rated supply is n=600 kilocalories, q=400 m 3/H, the circulating pump q=400 m 3/H, h=0.45 mpa, n=110 KW, and the burner 2n=45 KW. With 2 thermal devices, each thermal load n=212 kilocalories, q=300 m 3/h.
The maximum allowable use temperature of the actual operation of the heat conduction oil is set to be 280 ℃.
Since the heat using equipment operates with a small temperature difference, the inlet temperature of the heat using equipment 1# and the heat using equipment 2# is 270 ℃, the outlet temperature is 255 ℃, and the inlet-outlet temperature difference is only 15 ℃ (assuming 15 ℃, 12 ℃ to 16 ℃ are possible)
The temperature of the heat conducting oil outlet passing through the heat utilization equipment is higher (255 ℃), the heat of the heat conducting oil under the same flow rate is not fully utilized, and the return oil can only be heated to 270-280 ℃ due to the limitation of the highest temperature of the heat conducting oil after being heated by the heat source 1, so that the insufficient output of the heat source 1 is caused. The power of the circulating pump and the power of the burner 2 are fixed, so that the heat source 1 uses the same electricity consumption and only provides about 30-40% of heat supply. The electric power consumption is greatly wasted.
After the improvement of the application, the combined energy-saving system of the heat conduction oil heat source 1 and the main pipe large-temperature-difference operation and the heat equipment small-temperature-difference operation system is adopted.
For the convenience of analysis, relevant parameters are set according to actual conditions, the resistances of the corresponding branch pipes and valves are ignored, and the resistances of the main pipeline, the heat source 1 and the heat utilization equipment are respectively marked on the figures. As the basis of qualitative analysis.
The pressure value of the heat conduction oil after being pressurized by the first circulating pump 5 and passing through the heat source 1 is artificially set to be H=0.35 MPa, and the available pressure after pressure drop is set to be 0.05MPa through pipeline pressure loss. The pressure head of the first heat equipment 3 is 0.3MPa, Q=300 m 3/h, the pressure loss of the first heat equipment 3 is 0.15MPa, and the heat consumption is 212 ten thousand kilocalories.
The oil outlet pressure of the first heat equipment 3 is 0.14MPa, and the oil outlet temperature is 255 ℃. The extraction of the partial oil q=250 m 3/h and the extraction of the partial oil 270 ° C, Q =52 m 3/h from the oil supply manifold 8 is directly pumped into the second heat consumer 4 by the second circulation pump 29.
The second circulating pump 29 adopts variable frequency control, and can adjust the lift and flow at any time to meet the use requirement of 212 ten thousand cards of the heat consumption of the second heat consumption equipment 4.
The pressure head of the second circulating pump 29 only overcomes the resistance of the second heat utilization device 4, so that the flow and the lift are small. The power of the motor used is also much smaller. The third oil inlet valve 24 and the fourth oil inlet valve 26 can meet the oil supply amount entering the second circulating pump 29 through opening degrees, and the valves can be manually or automatically controlled.
In this way, to operate using 2 heat sources 1 originally, only 1 heat source 1 is operated, and the power of the burner 2 and the first circulating pump 5 of 1 heat source 1 is reduced. Through actual measurement, the electric power of 1 first circulating pump 5 can be basically saved.
The comparison shows that the main pipe system operates with large temperature difference and small flow rate, and the heat equipment operates with small temperature difference and large flow rate.
The oil supply and return flow of the oil supply main pipe 8 and the oil return main pipe 9 can be reduced, the heat supply load under the same flow is greatly improved, the capacities of the heat source 1 and the first circulating pump 5 can be fully exerted, the heat supply load can be improved, the heat supply requirement can be met, and a larger margin is provided.
The heat utilization equipment operates with small temperature difference and large flow, and has better hydraulic stability for the heat conduction oil system of the whole heat utilization equipment. And the amount of high-low temperature oil intake of the second circulation pump 29 can be adjusted according to the actual heat load and the actual heat temperature.
The second circulating pump 29 adopts variable frequency control to ensure the pressure and flow of the second heat utilization equipment 4 at any time so as to meet the heat load for equipment, and the hydraulic stability of the system is better.
In summary, the component for reducing the energy consumption of the heat conduction oil system provided by the utility model aims at the heat conduction oil system, the heat source and the main circulation system to operate with large temperature difference and small flow, and the heat utilization equipment adopts the technical scheme and the component with small temperature difference and large flow, so that the operation stability of the system can be greatly increased after the use, the heat supply quality of the heat utilization equipment is improved, the product combination rate of the heat utilization equipment is improved, the number of heat source use is reduced, the power consumption is reduced, and the energy saving purpose of the heat conduction oil system is achieved.
