Description

Technical Field

[0001] This utility model relates to the technical field of energy recovery devices, specifically a heat energy recovery device for power engineering. Background Technology

[0002] Power engineering studies the theories and technologies of energy conversion, transmission, and utilization in the engineering field, aiming to improve energy efficiency and reduce primary energy consumption and pollutant emissions. Currently, in the process of using thermal energy as a power source for processing, thermal energy is generally emitted directly through gas. Since the gas carries a large amount of thermal energy, the emission not only has a serious impact on the environment but also fails to effectively recover and utilize the thermal energy, resulting in heat loss and resource waste. To address these issues, the inventor proposes a heat recovery device for power engineering to solve the above problems. Utility Model Content

[0003] In order to address the problem that heat energy is generally directly emitted as gas during current processing using heat energy as a power source, the purpose of this utility model is to provide a heat energy recovery device for power engineering.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a heat recovery device for power engineering, comprising a housing, a water storage cylinder embedded in the top surface of the housing, an agitator in the water storage cavity of the water storage cylinder, the water storage cylinder comprising an outer shell and an inner shell, a spiral tube disposed between the outer shell and the inner shell, a connecting pipe fixedly connected to the bottom end of the spiral tube, an air outlet pipe fixedly connected to the top end of the spiral tube, a baffle fixedly connected to the inner side wall of the spiral tube, a filter cylinder fixedly connected to the end of the connecting pipe away from the spiral tube, an air inlet pipe connector fixedly connected to the input end of the filter cylinder, a filter screen disposed inside the filter cylinder, and a waste storage cylinder inserted and fixedly connected to the bottom surface of the filter cylinder.

[0005] Preferably, the baffle is semi-circular in shape, and there are several baffles, which are staggered with each other. When the high-temperature flue gas flows in the spiral tube, the baffles can block the high-temperature flue gas to slow down its flow rate, thereby increasing the contact time between the high-temperature flue gas and the water storage tank, and thus improving the heating efficiency of the water in the water storage tank. The multiple baffles are used to better slow down the flow rate of the high-temperature flue gas, and the staggered arrangement of the baffles avoids affecting the flow of the flue gas.

[0006] Preferably, a motor is installed above the water storage tank, and an extension shaft is fixedly connected to the output shaft of the motor. The agitator is fixedly sleeved on the extension shaft. An end cap is detachably installed at the opening of the water storage tank. A base is installed on the side wall of the motor, and the base is fixedly connected to the top surface of the end cap. A through-hole is provided on the top surface of the end cap, and the through-hole is offset from the motor. The motor is installed through the base. When the motor is started, the extension shaft rotates under the action of the motor output shaft, which in turn causes the agitator to rotate, thereby agitating the water in the water storage tank. This, in conjunction with the high-temperature flue gas in the spiral tube, ensures that the water is heated evenly. The water in the water storage tank can be removed or released through the through-hole.

[0007] Preferably, the end of the exhaust pipe furthest from the spiral tube passes through the housing, and a perforated sleeve is fixedly fitted at the end of the exhaust pipe. The flue gas that exchanges heat with the water storage tank is discharged through the exhaust pipe. The perforated sleeve protects the exhaust pipe from external debris and birds entering it. The filter screen is located between the connecting pipe and the storage cylinder. The lower part of the outer wall of the storage cylinder is provided with external threads, and a threaded cap is provided at the bottom of the storage cylinder. The threaded cap corresponds to and cooperates with the external threads, connecting the exhaust pipe of the combustion furnace to the inlet pipe joint, so that the high-temperature flue gas enters the filter cylinder. The filter screen can filter the particulate matter contained in the flue gas, so as to prevent the particulate matter from accumulating and clogging when the flue gas flows in the spiral tube due to the obstruction of the baffle inside the spiral tube, thus affecting the use of the spiral tube. The filtered particulate matter falls into the storage cylinder. By turning the threaded cap, the threaded cap can be opened through the cooperation of the threaded cap and the external threads, so as to clean the filtered particulate matter.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model can effectively recover and utilize the heat in high-temperature flue gas. A spiral tube is installed inside the water storage tank, and a baffle is installed inside the spiral tube. When the high-temperature flue gas flows inside the spiral tube, the baffle can block the high-temperature flue gas, thereby slowing down the flow speed of the high-temperature flue gas, thereby increasing the contact time between the high-temperature flue gas and the water storage tank, and thus improving the heating efficiency of the water in the water storage tank.

[0010] 2. In this utility model, a filter cylinder is provided at the opening of the connecting pipe. When high-temperature flue gas enters the filter cylinder, the particulate matter contained in the flue gas can be filtered through the filter screen to prevent the particulate matter from accumulating and clogging due to the obstruction of the baffle when the flue gas flows in the spiral tube, thereby affecting the use of the spiral tube, and also making it easier to clean the filtered particulate matter.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5As shown, this utility model provides a heat recovery device for power engineering, including a box 1. A water storage cylinder 13 is embedded in the top surface of the box 1. An agitator 19 is installed in the water storage cavity of the water storage cylinder 13. The water storage cylinder 13 includes an outer shell 14 and an inner shell 15. A spiral tube 9 is installed between the outer shell 14 and the inner shell 15. A connecting pipe 2 is fixedly connected to the bottom end of the spiral tube 9. An air outlet pipe 10 is fixedly connected to the top end of the spiral tube 9. A baffle 12 is fixedly connected to the inner side wall of the spiral tube 9. A filter cylinder 3 is fixedly connected to the end of the connecting pipe 2 away from the spiral tube 9. An air inlet pipe connector 4 is fixedly connected to the input end of the filter cylinder 3. A filter screen 5 is installed inside the filter cylinder 3. A waste storage cylinder 6 is inserted and fixedly connected to the bottom surface of the filter cylinder 3.

[0020] The baffle 12 is semi-circular in shape, and there are several baffles 12, which are staggered with each other.

[0021] By adopting the above technical solution, when the high-temperature flue gas flows in the spiral tube 9, the baffle 12 can block the high-temperature flue gas to slow down the flow speed of the high-temperature flue gas, thereby increasing the contact time between the high-temperature flue gas and the water storage tank 13, so as to improve the heating efficiency of the water in the water storage tank 13. Several baffles 12 are set to better slow down the flow speed of the high-temperature flue gas, and the several baffles 12 are staggered to avoid affecting the flow of flue gas.

[0022] A motor 17 is installed above the water storage cylinder 13. An extension shaft 18 is fixedly connected to the output shaft end of the motor 17. An agitator 19 is fixedly sleeved on the extension shaft 18. An end cap 16 is detachably installed at the opening of the water storage cylinder 13. A base 20 is installed on the side wall of the motor 17. The base 20 is fixedly connected to the top surface of the end cap 16. A through-hole 21 is provided through the top surface of the end cap 16, and the through-hole 21 is offset from the motor 17.

[0023] By adopting the above technical solution, the motor 17 is installed on the base 20. When the motor 17 is started, the extended shaft 18 rotates under the action of the output shaft of the motor 17, which in turn causes the agitator 19 to rotate, so as to agitate the water in the water storage tank 13, so as to cooperate with the high temperature flue gas in the spiral tube 9 to make the water evenly heated. The water in the water storage tank 13 can be taken out and put in through the port 21.

[0024] The end of the vent pipe 10 away from the spiral tube 9 passes through the box body 1, and the end of the vent pipe 10 is fixedly fitted with a hollow sleeve 11.

[0025] By adopting the above technical solution, the flue gas that exchanges heat with the water storage tank 13 is discharged through the exhaust pipe 10. The exhaust pipe 10 can be protected by the hollow sleeve 11 to prevent external debris and birds from entering the exhaust pipe 10.

[0026] The filter screen 5 is located between the connecting pipe 2 and the storage cylinder 6. The lower part of the outer wall of the storage cylinder 6 is provided with an external thread 7. The bottom of the storage cylinder 6 is provided with a threaded cover 8, which corresponds to and cooperates with the external thread 7.

[0027] By adopting the above technical solution, the exhaust pipe of the combustion furnace is connected to the inlet pipe connector 4 so that the high-temperature flue gas enters the filter cylinder 3. The filter screen 5 can filter the particulate impurities contained in the flue gas to prevent the particulate impurities from accumulating and clogging due to the obstruction of the baffle 12 inside the spiral tube 9 when the flue gas flows inside the spiral tube 9, thereby affecting the use of the spiral tube 9. The filtered particulate impurities fall into the impurity storage cylinder 6. By turning the threaded cover 8, the threaded cover 8 can be opened through the mutual cooperation between the threaded cover 8 and the external thread 7, so as to clean the filtered particulate impurities.

[0028] Working principle: When using this utility model, the exhaust pipe of the combustion furnace is connected to the air inlet pipe connector 4. The high-temperature flue gas enters the filter cylinder 3 through the air inlet pipe connector 4. The filter screen 5 can filter the particulate impurities contained in the flue gas. The filtered high-temperature flue gas enters the spiral tube 9 through the connecting pipe 2. The filtered particulate impurities fall into the impurity storage cylinder 6. By turning the threaded cover 8, the threaded cover 8 can be opened through the cooperation between the threaded cover 8 and the external thread 7, so as to clean the filtered particulate impurities.

[0029] When the high-temperature flue gas flows inside the spiral tube 9, the baffle 12 can block the high-temperature flue gas to slow down its flow rate, thereby increasing the contact time between the high-temperature flue gas and the water storage tank 13 and improving the heating efficiency of the water in the water storage tank 13. Several baffles 12 are set to better slow down the flow rate of the high-temperature flue gas, and the several baffles 12 are staggered to avoid affecting the flow of flue gas.
