Description

Technical Field

[0001] The utility model relates to the technical field of regenerative heat collection, in particular to a regenerative heat collection device for a thermal power plant. Background Art

[0002] During the power generation process of a thermal power plant, a large amount of surplus heat is generated. Generally, cooling water passes through a cooling tower to dissipate this surplus heat into the atmosphere, resulting in heat waste. Therefore, various regenerative heat collection devices have been proposed in the prior art. For example, a waste heat recovery device for a thermal power plant proposed in a Chinese utility model patent with the publication number CN215259899U. This device collects and processes the heat by setting up a waste heat recovery device, stores a sufficient amount of hot water by setting up a water tank to improve the utilization effect of waste heat, and purifies the discharged gas by setting up a filter box to reduce environmental pollution, solving the problems of insufficient waste heat utilization, reduced efficiency of thermal power generation, and being unfavorable for energy-saving production.

[0003] However, like most of the prior art, the above waste heat recovery device only transports heat through heat transfer, with a single way of regenerative heat utilization. Moreover, some of them also need to be equipped with water pumps, resulting in high energy consumption and low efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a regenerative heat collection device for a thermal power plant that can convert the regenerative heat collection of the power plant into kinetic energy, change the way of regenerative heat utilization, and improve the efficiency of regenerative heat collection and utilization.

[0005] A heat recovery collection device for a thermal power plant of the present utility model includes a heat transfer pipe and a water tank. The water tank is sleeved on the outer wall of the heat transfer pipe, and a cavity is provided between the water tank and the heat transfer pipe. It also includes a main piston cylinder, a main piston, a first push rod, a secondary piston cylinder, a secondary piston, a second push rod, and a crankshaft assembly. An endothermic liquid is filled in the cavity between the water tank and the heat transfer pipe. The lower end of the main piston cylinder extends into the cavity, and the upper end of the main piston cylinder is provided with an opening one and extends out of the outside of the water tank. The main piston is slidably installed in the main piston cylinder. The lower end of the first push rod is rotatably connected to the main piston. The secondary piston cylinder is located outside the water tank, and the upper end of the secondary piston cylinder is provided with an opening two. The secondary piston is slidably installed in the secondary piston cylinder. The lower end of the second push rod is rotatably connected to the secondary piston. The bottom of the secondary piston cylinder is connected to the bottom of the main piston cylinder through a first pipeline. The middle of the secondary piston cylinder and the middle of the main piston cylinder are connected through a second pipeline. The upper ends of the second push rod and the first push rod are both rotatably connected to the connecting rod journal of the crankshaft assembly. The crankshaft assembly is rotatably arranged outside the water tank through a bearing bracket. Flue gas or high-temperature cooling water is conveyed in the heat transfer pipe, and the heat in the flue gas or high-temperature cooling water heats the endothermic solution in the cavity of the heat transfer pipe and the water tank. A thermally sensitive expansion gas is filled in the main piston cylinder and the secondary piston cylinder. The endothermic solution heats and expands the thermally sensitive expansion gas at the lower end of the main piston cylinder, pushing the main piston upward in the main piston cylinder. The main piston drives the connecting rod journal of the crankshaft assembly to rotate through the first push rod, thereby driving the main shaft of the crankshaft assembly to rotate. The inertia of the crankshaft assembly drives the main piston to reciprocate in the main piston cylinder. When the main piston passes over the first pipeline, the thermally sensitive expansion gas in the main piston cylinder enters the secondary piston cylinder through the first pipeline. The thermally sensitive expansion gas dissipates heat and cools down and reduces its volume in the secondary piston cylinder. At the same time, the main shaft of the crankshaft assembly drives the secondary piston to move downward in the secondary piston cylinder through the second push rod, and the thermally sensitive expansion gas in the secondary piston cylinder is refluxed to the bottom of the main piston cylinder through the second pipeline, realizing the cyclic work of the endothermic solution on the thermally sensitive expansion gas. The end of the main shaft of the crankshaft assembly is connected to the drive shaft of an external working device, so that the main shaft of the crankshaft assembly drives external working devices such as water pumps to operate, achieving the purpose of converting the recovered heat in the power plant into kinetic energy, changing the way of heat recovery utilization, reducing energy consumption, and improving the efficiency of heat recovery utilization.

[0006] Preferably, it further includes a first check valve and a second check valve. A first check valve is provided in the first pipeline between the secondary piston cylinder and the main piston cylinder. The first check valve enables the main piston cylinder to communicate with the secondary piston cylinder unidirectionally. A second check valve is provided in the second pipeline between the secondary piston cylinder and the main piston cylinder. The second check valve enables the secondary piston cylinder to communicate with the main piston cylinder unidirectionally. Through the above settings, reverse cyclic flow of the thermally sensitive expansion gas is avoided.

[0007] Preferably, it further includes a plurality of fins, and a plurality of fins are evenly arranged on the outer wall of the heat transfer pipe. By providing a plurality of fins, the contact area between the heat transfer pipe and the endothermic solution is increased, and the collection efficiency of the waste heat of the flue gas or high-temperature cooling water in the heat transfer pipe is improved.

[0008] Preferably, it further includes an expansion tank and an expansion pipe. The expansion tank is installed on the water tank. The upper end of the expansion pipe is connected to the expansion tank, and the lower end of the expansion pipe extends into the cavity between the heat transfer pipe and the water tank. The cavity is communicated with the expansion tank through the expansion pipe. When the temperature of the heat-absorbing solution in the heat transfer pipe and the cavity of the water tank is too high, the heat-absorbing solution expands and enters the expansion tank through the expansion pipe. When the temperature of the heat-absorbing solution in the heat transfer pipe and the cavity of the water tank is too low, the heat-absorbing solution in the expansion tank contracts and enters the cavity between the heat transfer pipe and the water tank through the expansion pipe, improving the safety and stability of the device.

[0009] Preferably, it further includes a temperature sensor. The temperature sensor is installed on the water tank, and the probe of the temperature sensor extends into the cavity between the heat transfer pipe and the water tank. The temperature sensor detects the temperature of the heat-absorbing solution in the cavity between the heat transfer pipe and the water tank, which has good practicability.

[0010] Preferably, it further includes a first heat exchanger, a first conveying pipe, a compression pump, a second transducer, and a second conveying pipe. The first heat exchanger is arranged in the cavity between the heat transfer pipe and the water tank. The second transducer is located outside the water tank. The input end of the first conveying pipe is connected to the upper end of the first heat exchanger, the output end of the first conveying pipe is connected to the input end of the second transducer, a compression pump is arranged on the first conveying pipe, the input end of the second conveying pipe is connected to the output end of the second transducer, and the output end of the second conveying pipe is connected to the lower end of the first heat exchanger. The drive shaft of the compression pump is in transmission connection with the main shaft of the crankshaft assembly. A medium is filled in the first heat exchanger, the first conveying pipe, the second conveying pipe, and the second transducer. The crankshaft assembly drives the compression pump to operate. The compression pump compresses and pumps the medium in the first conveying pipe, so that the medium circulates in the first heat exchanger, the first conveying pipe, the second transducer, the second conveying pipe, and the first heat exchanger. The medium absorbs heat in the first heat exchanger and releases heat in the second transducer, realizing the collection, transportation, and reuse of waste heat. By setting the compression pump, the efficiency of the medium circulation is improved.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: realizing the cyclic work of the heat-absorbing solution on the thermally sensitive expansion gas, connecting the end of the main shaft of the crankshaft assembly to the drive shaft of an external working device, so that the main shaft of the crankshaft assembly drives external working devices such as water pumps to operate, realizing the purpose of converting the recovered heat in the power plant into kinetic energy, changing the way of recovered heat utilization, reducing energy consumption, and improving the efficiency of recovered heat collection and utilization.

The upper ends of both the second push rod 8 and the first push rod 5 are rotatably connected to the connecting rod journal of the crankshaft assembly 9. The crankshaft assembly 9 is rotatably arranged outside the water tank 2 through a bearing bracket. It also includes a first check valve 10 and a second check valve 11. The first check valve 10 is provided in the first pipeline between the secondary piston cylinder 6 and the main piston cylinder 3, and the first check valve 10 enables the main piston cylinder 3 to communicate unidirectionally with the secondary piston cylinder 6. The second check valve 11 is provided in the second pipeline between the secondary piston cylinder 6 and the main piston cylinder 3, and the second check valve 11 enables the secondary piston cylinder 6 to communicate unidirectionally with the main piston cylinder 3. It also includes a plurality of fins 12, and a plurality of fins 12 are uniformly arranged on the outer wall of the heat transfer pipe 1.

[0022] The heat transfer pipe 1 conveys flue gas or high-temperature cooling water. The heat in the flue gas or high-temperature cooling water heats the heat-absorbing solution in the cavities of the heat transfer pipe 1 and the water tank 2. The main piston cylinder 3 and the auxiliary piston cylinder 6 are filled with thermally sensitive expansion gas. The heat-absorbing solution heats and expands the thermally sensitive expansion gas at the lower end of the main piston cylinder 3, pushing the main piston 4 upward in the main piston cylinder 3. The main piston 4 drives the connecting rod journal of the crankshaft assembly 9 to rotate through the first push rod 5, thereby driving the main shaft of the crankshaft assembly 9 to rotate. The inertia of the crankshaft assembly 9 drives the main piston 4 to reciprocate in the main piston cylinder 3. When the main piston 4 passes over the first pipeline, the thermally sensitive expansion gas in the main piston cylinder 3 enters the auxiliary piston cylinder 6 through the first pipeline. The thermally sensitive expansion gas dissipates heat and cools down and reduces its volume in the auxiliary piston cylinder 6. At the same time, the main shaft of the crankshaft assembly 9 drives the auxiliary piston 7 to move downward in the auxiliary piston cylinder 6 through the second push rod 8, returning the thermally sensitive expansion gas in the auxiliary piston cylinder 6 to the bottom of the main piston cylinder 3 through the second pipeline, realizing the cyclic work of the heat-absorbing solution on the thermally sensitive expansion gas. The end of the main shaft of the crankshaft assembly 9 is connected to the drive shaft of an external working device, enabling the main shaft of the crankshaft assembly 9 to drive external working devices such as water pumps to operate, achieving the purpose of converting the regenerative heat collection in the power plant into kinetic energy, changing the way of regenerative heat utilization, reducing energy consumption, and improving the efficiency of regenerative heat collection and utilization. By setting the one-way valve 10 and the one-way valve 11, reverse cyclic flow of the thermally sensitive expansion gas is avoided. By setting a plurality of fins 12, the contact area between the heat transfer pipe 1 and the heat-absorbing solution is increased, improving the collection efficiency of the waste heat of the flue gas or high-temperature cooling water in the heat transfer pipe 1.

The temperature sensor 15 is installed on the water tank 2, and the probe of the temperature sensor 15 extends into the cavity between the heat transfer pipe 1 and the water tank 2.

[0025] The temperature sensor 15 detects the temperature of the heat-absorbing solution in the cavities of the heat transfer pipe 1 and the water tank 2. When the temperature of the heat-absorbing solution in the cavities of the heat transfer pipe 1 and the water tank 2 is too high, the heat-absorbing solution expands and enters the expansion tank 13 through the expansion pipe 14. When the temperature of the heat-absorbing solution in the cavities of the heat transfer pipe 1 and the water tank 2 is too low, the heat-absorbing solution in the expansion tank 13 contracts and enters the cavities of the heat transfer pipe 1 and the water tank 2 through the expansion pipe 14, improving the safety and stability of the device.

The main piston 4 drives the connecting rod journal of the crankshaft assembly 9 to rotate through the first push rod 5, thereby driving the main shaft of the crankshaft assembly 9 to rotate. The inertia of the crankshaft assembly 9 drives the main piston 4 to reciprocate in the main piston cylinder 3. After that, when the main piston 4 passes over the first pipeline, the thermally expandable gas in the main piston cylinder 3 enters the auxiliary piston cylinder 6 through the first pipeline.
