Description

Technical Field

[0001] This application relates to the technical field of air compressor tailstock utilization equipment, and in particular to an industrial air compressor exhaust waste heat recovery and utilization system. Background Art

[0002] Industrial air compressors are one of the indispensable important equipment in modern industrial production and are widely used in multiple fields such as manufacturing, mining, chemical industry, and food processing. Industrial air compressors compress air and store it in an air storage tank to provide a power source for various pneumatic tools and automated equipment. During the use of industrial air compressors, high-temperature gases are discharged. To avoid heat loss, heat exchangers are usually used to recover the heat in the discharged high-temperature gases and reuse it. When using a heat exchanger to recover waste heat, a spraying device or a filtering device is usually used to filter the high-temperature gases to prevent dust from entering the heat exchanger and causing damage to the heat exchanger. However, when using a spraying device to filter the gases, the spraying liquid released by the spraying device will exchange heat with the high-temperature gases, resulting in heat loss. When using a filtering device to filter the high-temperature gases, the filtering device will reduce the flow rate of the high-temperature gases, resulting in an increase in the transportation time of the high-temperature gases, thereby causing heat loss during transportation.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0038] As Figures 1 to 3 shown, the present application provides an industrial air compressor exhaust waste heat recovery and utilization system, including an industrial air compressor (not shown in the figure), a heat exchanger 100, and a transportation mechanism 200. The industrial air compressor has an exhaust port (not shown in the figure) and an intake port (not shown in the figure). The heat exchanger 100 has an intake pipe 110, an exhaust pipe 120, a liquid inlet pipe 130, and a liquid discharge pipe 140. The transportation mechanism 200 includes a fan 210, a separation cylinder 220, a deflector 230, a waste discharge cylinder 240, and an opening and closing valve 250. The fan 210 is communicated with the exhaust port. The separation cylinder 220 is arranged between the fan 210 and the intake pipe 110. The deflector 230 is installed in the separation cylinder 220 and is configured to direct the gas so that the gas advances spirally. The waste discharge cylinder 240 is connected to one end of the separation cylinder 220 away from the fan 210 and is communicated with the separation cylinder 220. It is also configured to collect impurities in the separation cylinder 220. The opening and closing valve 250 is installed at one end of the waste discharge cylinder 240 away from the separation cylinder 220 and is used to control the opening and closing of the end of the waste discharge cylinder 240 away from the separation cylinder 220.

[0039] An industrial air compressor exhaust heat recovery and utilization system provided by the present application, during use, under the action of the separation cylinder 220 and the deflector 230, can make the high-temperature gas discharged from the industrial air compressor spiral forward in the separation cylinder 220, thereby being able to centrifuge impurities and then separate the impurities from the high-temperature gas. Compared with the related art, the separation cylinder 220 and the deflector 230 can quickly separate impurities from the high-temperature gas in a limited space and will not affect the flow rate of the high-temperature gas, effectively avoiding heat loss and having a high recovery efficiency. Moreover, through the impurity discharge cylinder 240, it can be used to collect the impurities separated from the high-temperature gas, improving the convenience of use of the device. In addition, through the opening and closing valve 250, it is convenient for the staff to clean the impurities in the impurity discharge cylinder 240, which helps to further improve the convenience of use of the device.

[0040] In an embodiment of the present application, please refer to Figures 1 to 3 , the separation cylinder 220 includes a first conical cylinder 221, a mounting cylinder 222, a second conical cylinder 223, and a third conical cylinder 224. The mounting cylinder 222 is installed at one end of the first conical cylinder 221 away from the fan 210. The second conical cylinder 223 is installed at one end of the mounting cylinder 222 away from the first conical cylinder 221. The third conical cylinder 224 is connected to one end of the second conical cylinder 223 away from the mounting cylinder 222.

[0041] Among them, the first conical cylinder 221 is arranged to gradually expand along the gas conveying direction; the second conical cylinder 223 is arranged to gradually contract along the gas conveying direction; the third conical cylinder 224 is arranged to gradually expand along the gas conveying direction.

[0042] With such a setting, the high-temperature gas is conveyed to the first conical cylinder 221 under the action of the fan 210. Since the first conical cylinder 221 is arranged to gradually expand along the gas conveying direction, it can avoid the gas being concentrated and conveyed to the central position of the deflector 230, facilitating the deflector 230 to deflect the gas, thereby helping to improve the impurity removal effect of the device. Since the second conical cylinder 223 is arranged to gradually contract along the gas conveying direction and the third conical cylinder 224 is arranged to gradually expand along the gas conveying direction, compared with being set as a cylindrical cylinder in the related art, it helps to improve the separation effect of the separation cylinder 220 on impurities, thereby being able to effectively protect the heat exchanger 100, helping to improve the heat exchange efficiency of the heat exchanger 100, and also helping to extend the service life of the heat exchanger 100.

[0043] In an embodiment of the present application, please refer to Figures 1 to 3 together, the separation cylinder 220 further includes an outer cylinder 225, an inner cylinder 226, and a baffle 227. The outer cylinder 225 is connected to one end of the third conical cylinder 224 away from the second conical cylinder 223. The inner cylinder 226 is arranged inside the outer cylinder 225. The baffle 227 is sealingly connected between the outer cylinder 225 and the inner cylinder 226.

[0044] With such an arrangement, under the action of the outer cylinder 225 and the baffle 227, it is possible to prevent the separated impurities from leaking out of the separation cylinder 220, facilitating the entry of impurities into the impurity discharge cylinder 240. Under the action of the inner cylinder 226, the high-temperature gas after separation can be transported to the intake pipe 110 of the heat exchanger 100, enabling the heat exchanger 100 to recover the heat in the high-temperature gas.

[0045] In an embodiment of the present application, referring to Figures 1 to 3 , the deflector 230 includes a deflector block 231 and a plurality of deflector plates 232. The deflector block 231 is disposed inside the separation cylinder 220, and the plurality of deflector plates 232 are all connected between the separation cylinder 220 and the deflector block 231.

[0046] With such an arrangement, under the action of the deflector block 231, the high-temperature gas can be guided to the plurality of deflector blocks 231, facilitating the deflection of the high-temperature gas by the plurality of deflector plates 232. Under the action of the plurality of deflector plates 232, the transport direction of the high-temperature gas can be changed, causing the high-temperature gas to advance in a spiral manner. During the spiral process, the high-temperature gas will drive the impurities to advance in a spiral manner, and the impurities will generate a centrifugal force during the spiral process, thereby being able to be separated from the gas. The separation effect is good, and it will not affect the heat exchanger 100's recovery of the heat in the high-temperature gas.

[0047] In an embodiment of the present application, please refer to Figures 1 to 3 , the impurity discharge cylinder 240 includes a first storage cylinder 241, a second storage cylinder 242, a connecting plate 243, and a mounting frame 244. The first storage cylinder 241 is connected to one end of the separation cylinder 220 away from the blower 210. The second storage cylinder 242 is disposed at one end of the first storage cylinder 241 away from the separation cylinder 220 and is in communication with the first storage cylinder 241. The connecting plate 243 is connected between the first storage cylinder 241 and the second storage cylinder 242. The mounting frame 244 is installed inside the second storage cylinder 242; wherein, the diameter of the first storage cylinder 241 is smaller than the diameter of the second storage cylinder 242.

[0048] The transport mechanism 200 further includes a bearing member 260. The bearing member 260 is installed on the mounting frame 244, plugs the first storage cylinder 241, and is further configured to release the plugging when the weight of the impurities carried reaches a preset threshold.

[0049] It should be noted here that the preset thresholds above and below refer to the preset weight of the impurities.

[0050] Specifically, when the staff cleans the impurities in the impurity discharge cylinder 240, the opening and closing valve 250 needs to be opened to remove the impurities in the impurity discharge cylinder 240. However, after the opening and closing valve 250 is opened, the separation cylinder 220 will be connected to the external environment, which is likely to cause heat loss. Moreover, the impurities and high-temperature gas will overflow from the opening and closing valve 250, affecting the staff's cleaning of the impurities and prone to safety accidents.

[0051] With such a setting, under the cooperation of the first storage cylinder 241, the second storage cylinder 242, the connecting plate 243, the mounting bracket 244 and the bearing member 260, when cleaning the impurities, the bearing member 260 blocks the first storage cylinder 241, effectively avoiding heat loss, thereby improving the heat recovery efficiency of the device. Moreover, when cleaning the impurities, it effectively avoids the overflow of impurities and gas, facilitating the staff to clean the impurities and contributing to improving the convenience of use.

[0052] In an embodiment of the present application, please refer to Figures 1 to 3 , the bearing member 260 includes a bearing rod 261, a bearing platform 262 and a bearing elastic structure 263. The bearing rod 261 passes through the mounting bracket 244 and can move relative to the mounting bracket 244. The bearing platform 262 is connected to one end of the bearing rod 261 close to the first storage cylinder 241. The bearing elastic structure 263 is sleeved on the bearing rod 261 and abuts between the mounting bracket 244 and the bearing platform 262.

[0053] With such a setting, under the action of the bearing elastic structure 263, the bearing platform 262 can be abutted against the connecting plate 243, so that the bearing platform 262 blocks the first storage cylinder 241. When the weight of the impurities exceeds the preset threshold, the bearing elastic structure 263 is compressed, and the bearing platform 262 is separated from the connecting plate 243, and the impurities can enter the second storage cylinder 242 from the first storage cylinder 241. In this way, the impurities can enter the second storage cylinder 242 from the first storage cylinder 241 in a sealed state, effectively avoiding heat loss. Moreover, under the action of the mounting bracket 244, the bearing rod 261 can be guided, which helps to improve the movement stability of the bearing rod 261, and further helps to improve the movement stability of the bearing platform 262 and avoid the bearing platform 262 from getting stuck.

[0054] Optionally, the bearing elastic structure 263 is set as a spring or a spring sheet.

[0055] In an embodiment of the present application, refer to Figures 1 to 3 , the impurity discharge cylinder 240 further includes at least one heat insulation ring 245, and at least one heat insulation ring 245 is installed on the connecting plate 243.

[0056] With such a setting, through at least one heat insulation ring 245, heat can be prevented from being conducted from the gap between the connecting plate 243 and the bearing platform 262 into the second storage cylinder 242. When cleaning impurities, heat loss is also effectively avoided, which helps to further improve the heat recovery efficiency.

[0057] In an embodiment of the present application, please refer to Figures 1 to 3 , both the industrial air compressor and the transportation mechanism 200 are provided with two. The transportation mechanism 200 further includes a first transportation pipe 270, a second transportation pipe 280, and a third transportation pipe 290. The first transportation pipe 270 is arranged between the exhaust port and the fan 210. The second transportation pipe 280 is arranged between the separation cylinder 220 and the intake pipe 110. The third transportation pipe 290 is installed at the intake port. The industrial air compressor exhaust waste heat recovery and utilization system further includes an intake three-way joint 400 and an exhaust three-way joint 500. The intake three-way joint 400 is installed on the intake pipe 110 and connects the two second transportation pipes 280 to the intake pipe 110. The exhaust three-way joint 500 is installed on the exhaust pipe 120 and connects the two third transportation pipes 290 to the exhaust pipe 120.

[0058] With such a setting, under the action of the first transportation pipe 270 and the second transportation pipe 280, high-temperature gas can be transported to the intake pipe 110. Under the action of the third transportation pipe 290, after recovering the heat in the gas, it can be returned to the intake port of the industrial air compressor to supply gas to the industrial air compressor. Under the action of the intake three-way joint 400 and the exhaust three-way joint 500, the heat exchanger 100 can simultaneously recover the waste heat of two industrial air compressors, greatly improving the utilization rate of the heat exchanger 100.

[0059] In an embodiment of the present application, please refer to Figures 1 to 3 together, the industrial air compressor exhaust waste heat recovery and utilization system further includes a bypass mechanism 600, and the bypass mechanism 600 is installed between the two first transportation pipes 270.

[0060] The transportation mechanism 200 includes a transportation switch valve 300. The transportation switch valve 300 is installed on the first transportation pipe 270 and is located between the fan 210 and the bypass mechanism 600.

[0061] The bypass mechanism 600 includes a bypass pipe 610 and a bypass switch valve 620. The bypass pipe 610 is installed between the two first transportation pipes 270, and the bypass switch valve 620 is installed on the bypass pipe 610.

[0062] Specifically, when the heat exchanger 100 simultaneously recovers the waste heat of two industrial air compressors, when one of the transportation mechanisms 200 fails, the transportation mechanism 200 needs to be disassembled from the corresponding industrial air compressor. Therefore, during the maintenance process, heat loss of the corresponding industrial air compressor will occur, and the recovery efficiency is relatively low.

[0063] With such a setting, when maintaining the transportation mechanism 200, the staff closes the transportation switch valve 300 on the side of the transportation mechanism 200 to be maintained and opens the bypass switch valve 620. Under the action of the bypass pipe 610, the two first transportation pipes 270 can be connected, and the two industrial air compressors transport high-temperature gas to the heat exchanger 100 through the same first transportation pipe 270, effectively avoiding heat loss.

[0064] The working principle of the device is as follows: The industrial air compressor discharges high-temperature gas from the exhaust port. Under the action of the fan 210, the high-temperature gas is transported from the first transportation pipe 270 to the first conical cylinder 221. Under the action of the guide block 231 and multiple guide plates 232, the high-temperature gas spirally advances in the second conical cylinder 223 and the third conical cylinder 224. During the spiral process of the high-temperature gas, the impurities in the high-temperature gas gradually move towards the inner peripheral sides of the second conical cylinder 223 and the third conical cylinder 224 under the action of centrifugal force. After the impurities are separated from the high-temperature gas, the impurities move between the outer cylinder 225 and the inner cylinder 226 until the impurities enter the first storage cylinder 241. After the impurities are separated from the high-temperature gas, the high-temperature gas is transported from the inner cylinder 226 to the second transportation pipe 280, and then from the second transportation pipe 280 to the intake pipe 110, and finally enters the heat exchanger 100 from the intake pipe 110. The heat exchanger 100 inputs high-temperature gas from the intake pipe 110, outputs low-temperature gas from the exhaust pipe 120, inputs cold water from the liquid inlet pipe 130 and outputs hot water from the liquid discharge pipe 140. The hot water output by the heat exchanger 100 can be used for industrial production, domestic water, etc., so as to achieve the purpose of recovering the waste heat of the industrial air compressor and reusing the waste heat. When the gravity of the impurities acting on the bearing platform 262 is greater than the elastic force of the bearing elastic structure 263 acting on the bearing platform 262, the bearing platform 262 will move towards the mounting frame 244. At this time, the bearing elastic structure 263 is gradually compressed, and a gap appears between the bearing platform 262 and the connecting plate 243. The impurities in the first storage cylinder 241 enter the second storage cylinder 242 through the gap until the gravity of the impurities acting on the bearing platform 262 is less than the elastic force of the bearing elastic structure 263 acting on the bearing platform 262. Then the bearing platform 262 will move towards the connecting plate 243 until the bearing platform 262 abuts against the connecting plate 243. At this time, the first storage cylinder 241 and the second storage cylinder 242 are blocked by the bearing platform 262. The staff opens the opening and closing valve 250 to clean the impurities in the second storage cylinder 242.

[0065] One or more embodiments of the present application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application shall be included within the protection scope of the present application.
