Description

Technical Field

[0001] This utility model relates to the field of low-temperature heat energy recovery technology for flue gas acid production, and in particular to a low-temperature heat energy recovery device for flue gas acid production based on ion liquid desulfurization. Background Technology

[0002] In industrial production, flue gas desulfurization is a crucial step in reducing sulfur dioxide (SO2) emissions. Ion-liquid desulfurization technology, due to its high efficiency, environmental friendliness, and recyclability, has gradually become one of the mainstream methods for flue gas desulfurization. However, the desulfurization process generates a large amount of low-temperature heat energy (typically 50℃~150℃). Directly releasing this heat energy not only wastes energy but also causes thermal pollution to the environment. Therefore, those skilled in the art provide a low-temperature heat energy recovery device for flue gas-to-acid production based on ion-liquid desulfurization to solve the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-temperature heat energy recovery device for flue gas acid production based on ionic liquid desulfurization.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A low-temperature heat recovery device for flue gas acid production based on ion liquid desulfurization includes a base. A heat pump is fixedly installed in the middle of the top surface of the base. A delivery pipe is inserted into the top of the heat pump. A heat exchanger is inserted into one end of the delivery pipe. An air inlet pipe is inserted into one side of the output end of the heat exchanger. An installation plate is fixedly installed at one end of the air inlet pipe. A connecting plate is threaded onto the surface of the installation plate. A filter assembly is fixedly installed on the front side of the connecting plate. A water storage tank is fixedly installed on one side of the front side of the heat pump. A heat-conducting plate is provided on one side of the inner wall of the water storage tank. A baffle is threaded onto the front side of the water storage tank. A drain pipe is inserted into the middle of the front side of the baffle.

[0006] The filter assembly includes a fixed cylinder that is inserted into the surface of the connecting plate. A connecting ring is fixedly connected to the front of the fixed cylinder. A blower is fixedly installed on the inner wall of the connecting ring. A connecting rod is fixedly connected to the axis on the front of the blower. A brush rod is fixedly connected to one end of the connecting rod. An interception net is fixedly connected to the inner wall of the fixed cylinder.

[0007] As a further embodiment of this utility model, the surface of the interception net is in contact with the brush rod, the inner bottom wall of the fixed cylinder is provided with a leakage groove, and a storage box is provided at the bottom edge of the leakage groove.

[0008] As a further embodiment of this utility model, an observation window is provided on the front of the storage box, and a transparent plate is embedded in the surface of the observation window.

[0009] As a further embodiment of this utility model, a control box is provided on the other side of the front of the heat pump, and both sides of the front of the control box are hinged with door panels.

[0010] As a further embodiment of this utility model, a gas guide pipe is inserted into one side of the top surface of the heat-conducting plate, and one end of the gas guide pipe is inserted into the interior of the heat exchanger.

[0011] As a further embodiment of this utility model, a device box is provided on one side of the heat exchanger, and a connecting pipe is inserted into the bottom of the device box.

[0015] 1.

The recovered low-temperature heat energy is then transported to the surface of the interception net by a blower. As the blower rotates, it drives the connecting rod and brush rod to clean the foreign objects on the surface of the interception net. The cleaned foreign objects then fall into the storage box through the leakage groove, thus facilitating the filtration and cleaning of foreign objects inside the low-temperature heat energy.

Then, the heat conduction plate can transport the high-temperature heat energy to the water source inside the water storage tank, so that the water source inside the water storage tank can be heated, thereby facilitating the personnel to heat the water source.

[0022] 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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0023] Reference Figures 1-4 A low-temperature heat energy recovery device for flue gas acid production based on ion liquid desulfurization includes a base 1, a heat pump 2 fixedly installed in the middle of the top surface of the base 1, a delivery pipe 3 inserted into the top of the heat pump 2, a heat exchanger 4 inserted into one end of the delivery pipe 3, a control box 14 set on the other side of the front of the heat pump 2, and a door 15 hinged to both sides of the front of the control box 14.

[0024] When personnel need to recover the low-temperature heat energy from flue gas acid production, they can move the base 1 and heat pump 2 to a suitable position. Then, they can connect the external recovery pipe using the connecting ring 82. The external low-temperature heat energy is then transported along the fixed cylinder 81 to the surface of the interception net 86. The interception net 86 can then intercept impurities contained within the low-temperature heat energy. Afterwards, personnel can reconnect the power to the blower fan 83, causing it to rotate the connecting rod 84 and the brush rod 85. The brush rod 85 then cleans the dust or foreign objects from the surface of the interception net 86, causing the foreign objects to fall into the storage box 1 through the discharge groove. The low-temperature heat energy, after being filtered, is then transported to the heat exchanger 4. The heat exchanger 4 converts the low-temperature heat energy into high-temperature heat energy, which is then transported through the air guide pipe 16 to the heat conduction plate 10. The heat conduction plate 10 then transports the heat energy to the water storage tank 9, thereby heating the water source inside the water storage tank 9. This allows personnel to heat the water source. During the low-temperature heat energy recovery process, the heat exchanger 4 and heat pump 2 can be started using the equipment box 17 and control box 14, thus facilitating the recovery of low-temperature heat energy.

[0025] In this utility model, an air inlet pipe 5 is inserted into one side of the output end of the heat exchanger 4. An installation plate 6 is fixedly installed at one end of the air inlet pipe 5. A connecting plate 7 is threadedly connected to the surface of the installation plate 6. A filter assembly 8 is fixedly installed on the front of the connecting plate 7. The filter assembly 8 includes a fixed cylinder 81 inserted into the surface of the connecting plate 7. A connecting ring 82 is fixedly connected to the front of the fixed cylinder 81. A blower 83 is fixedly installed on the inner wall of the connecting ring 82. A connecting rod 84 is fixedly connected to the axis on the front of the blower 83. A brush rod 85 is fixedly connected to one end of the connecting rod 84. An interception net 86 is fixedly connected to the inner wall of the fixed cylinder 81. The surface of the interception net 86 is in contact with the brush rod 85. A leakage groove is opened in the inner bottom wall of the fixed cylinder 81. A storage box 13 is provided at the bottom edge of the leakage groove. An observation window is opened on the front of the surface of the storage box 13. A transparent plate is embedded in the surface of the observation window.

[0026] With the filter assembly 8 in place, when personnel are recovering low-temperature heat energy, they can use the connecting ring 82 to connect the external low-temperature heat energy. The recovered low-temperature heat energy is then transported to the surface of the interception net 86 by the blower 83. Subsequently, as the blower 83 rotates, it can drive the connecting rod 84 and the brush rod 85 to clean the foreign objects on the surface of the interception net 86. The cleaned foreign objects then fall into the storage box 13 through the leakage groove, thus facilitating the filtering and cleaning of foreign objects inside the low-temperature heat energy.

[0027] In particular, a water storage tank 9 is fixedly installed on one side of the front of the heat pump 2, a heat conduction plate 10 is provided on one side of the inner wall of the water storage tank 9, a baffle 11 is threadedly connected to the front of the water storage tank 9, a drain pipe 12 is inserted into the middle of the front of the baffle 11, a gas guide pipe 16 is inserted into one side of the top surface of the heat conduction plate 10, and one end of the gas guide pipe 16 is inserted into the interior of the heat exchanger 4.

[0028] With the installation of water tank 9, heat conduction plate 10 and drain pipe 12, during the process of personnel recovering low-temperature heat energy, its heat exchanger 4 can convert low-temperature heat energy into high-temperature heat energy. Part of the high temperature is transported to the interior of heat conduction plate 10 through air guide pipe 16. Then, heat conduction plate 10 can transport the high temperature to the water source inside water tank 9, so that the water source inside water tank 9 can be heated, thereby facilitating the function of personnel heating water source.

[0029] In particular, an equipment box 17 is provided on one side of the heat exchanger 4, a connecting pipe is inserted into the bottom of the equipment box 17, a fixed box 18 is inserted into one end of the connecting pipe, a card is snapped into the front of the fixed box 18, an anti-oxidation film is attached to the outer surface of the heat pump 2, and an anti-slip pad is provided at the bottom of the base 1.

[0030] With the installation of the equipment box 17 and the fixed box 18, when personnel need to use the heat exchanger 4, the heat exchanger 4 can be operated by using the equipment box 17, which makes it convenient for personnel to use.

[0031] Working principle: When personnel need to recover the low-temperature heat energy from flue gas acid production, they can move the base 1 and heat pump 2 to a suitable position. Then, they can connect the external recovery pipe using the connecting ring 82. The external low-temperature heat energy is then transported along the fixed cylinder 81 to the surface of the interception net 86. The interception net 86 intercepts impurities contained within the low-temperature heat energy. Afterwards, the personnel can reconnect the power to the blower 83, causing it to rotate the connecting rod 84 and brush rod 85. The brush rod 85 then cleans the dust or foreign objects from the surface of the interception net 86, causing the foreign objects to fall into the storage channel. The low-temperature heat energy, after being filtered, is transported to the heat exchanger 4 inside the storage box 13. The heat exchanger 4 then converts the low-temperature heat energy into high-temperature heat energy. The high-temperature portion converted inside the heat exchanger 4 is then transported through the air guide pipe 16 to the heat conduction plate 10. The heat conduction plate 10 then transports the heat energy to the water storage tank 9, thereby heating the water source inside the water storage tank 9. This allows personnel to heat the water source. During the low-temperature heat energy recovery process, the heat exchanger 4 and the heat pump 2 can be started using the equipment box 17 and the control box 14, thus facilitating the recovery of low-temperature heat energy.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
