Description

Technical Field

[0001] The invention belongs to the technical field of boiler waste heat recovery, in particular to a boiler continuous waste heat recovery device. Background Art

[0002] Industrial boiler products are mainly divided into two categories: steam boilers and coal-fired boilers. In order to ensure that the water quality of steam boilers meets the standards, continuous blowdown operation must be implemented. The water temperature discharged during the blowdown process is the same as the saturated water temperature in the boiler. This blowdown process consumes about 1% of the total energy. If this part of high-temperature sewage is directly discharged, it will not only waste energy, but also pollute the environment. Therefore, a variety of waste heat recovery devices have appeared on the market to solve this problem.

[0003] For example, Chinese patent application CN114777532B discloses a boiler-type waste heat recovery device, which relates to the technical field of waste heat recovery devices, and includes a base, a cylinder is fixedly connected to the middle of the upper end face of the base, a wastewater inlet pipe is fixedly connected to the left end face of the cylinder, a wastewater outlet pipe is fixedly connected to the right end face of the cylinder, and a driving mechanism is arranged at the front of the outer wall of the cylinder; brackets are fixedly connected to the left and right sides of the inner cavity of the cylinder, a mixing mechanism is arranged between the brackets on the left and right sides, and a heat exchange mechanism is arranged at the front and rear sides of the upper end face of the base. This technology, through the arrangement of the heat exchange plate, can absorb the heat of the high-temperature wastewater in the inner cavity of the cylinder, and the heat exchange coil is fixedly connected to the heat exchange plate. By starting the output pump, the heat exchange liquid in the liquid storage tank can enter the heat exchange coil through the liquid inlet pipe, and then be discharged from the liquid outlet pipe, thereby realizing the circulation of the heat exchange liquid, so that the entire device realizes the function of recovering the waste heat of the wastewater.

[0004] Although the above technology can absorb the residual heat energy in the wastewater through the heat exchange plate, since the wastewater contains a large amount of impurities, when the wastewater enters the cylinder, the impurities will adhere to the inside of the heat exchange plate, thereby affecting the heat exchange plate to absorb heat energy. As time goes by, the heat exchange efficiency decreases, which in turn affects the efficiency of waste heat recovery.

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] like Figures 1 to 8 As shown, a boiler-tank waste heat recovery device described in the present invention includes a recovery part, a material guiding mechanism, a filtering mechanism, a circulation mechanism, a cleaning mechanism and a control mechanism.

[0047] The recovery part includes a storage tank 2, a supporting seat 1 and a feed pipe 11. The storage tank 2 is fixedly mounted on the upper end of the supporting seat 1. The supporting seat 1 is used to provide installation and support for the storage tank 2. The storage tank 2 is used to provide space for absorbing heat energy in the waste.

[0048] The feed pipe 11 extends to the inner cavity of the storage tank 2 and is distributed in a spiral shape inside the storage tank 2. The feed pipe 11 is connected to an external water pump to introduce external unheated materials, thereby absorbing heat energy in the waste material to achieve the effect of preheating the material.

[0049] The material guiding mechanism includes a feed pipe 4 and a discharge pipe 3, which are respectively distributed at the two ends of the storage tank 2, wherein the outer walls of the feed pipe 4 and the discharge pipe 3 are both provided with flanges, the feed pipe 4 is used for inputting hot waste, and the discharge pipe 3 is used for discharging materials inside the storage tank 2.

[0050] The filtering mechanism includes a mounting frame 8, a filter plate 19 and a connecting tube 9. The connecting tube 9 is fixedly mounted inside the feed pipe 4. The waste inside the feed pipe 4 enters the inner cavity of the storage tank 2 through the connecting tube 9. The filter plate 19 is mounted on one side of the connecting tube 9 through the mounting frame 8, wherein the mounting frame 8 is detachably mounted on the outer wall of the connecting tube 9. The filter plate 19 is fixedly mounted inside the mounting frame 8 and is used to filter impurities in the waste. When the waste is input into the storage tank 2, the impurities are prevented from adhering to the outer wall of the delivery pipe 11, thereby maintaining the heat exchange efficiency between the waste and the material inside the delivery pipe 11.

[0051] The circulation mechanism is used to control the circulation flow of the waste liquid in the inner cavity of the storage tank 2, and is used to increase the heat exchange time by controlling the circulation flow of the waste material in the inner cavity of the storage tank 2.

[0052] The cleaning mechanism includes a cleaning scraper 16 and a transmission shaft 20. The transmission shaft 20 is rotatably set on one side of the mounting frame 8, and one end of the transmission shaft 20 passes through the filter plate 19. The transmission shaft 20 passes through the middle of the filter plate 19. The cleaning scraper 16 is fixedly mounted on the outer wall of the transmission shaft 20. The cleaning scraper 16 is located on the side of the waste input. The cleaning scraper 16 is driven to rotate by rotating the transmission shaft 20, thereby scraping off impurities attached to the outer wall of the filter plate 19, preventing the filter plate 19 from being blocked, and maintaining the filtering efficiency.

[0053] In order to improve the cleaning efficiency of the cleaning scraper 16 when scraping the outer wall of the filter plate 19, the side wall of the cleaning scraper 16 is inclined, and the outer wall of the cleaning scraper 16 is fitted with the outer wall of the filter plate 19. By inclined the side wall of the cleaning scraper 16, the cleaning efficiency of the cleaning scraper 16 when scraping the filter plate 19 can be effectively improved.

[0054] A bearing frame 10 is fixedly mounted on the outer wall of the mounting frame 8 , and a bearing tube 14 is fixedly mounted inside the bearing frame 10 . The bearing frame 10 is provided to support the bearing tube 14 .

[0055] One end of the transmission shaft 20 extends to the inner cavity of the supporting tube 14 and is elastically connected to the supporting tube 14 through a torsion spring. After the transmission shaft 20 is rotated to control the cleaning scraper 16 to scrape off impurities, the elastic force of the torsion spring is used to control the transmission shaft 20 to reset, thereby controlling the cleaning scraper 16 to reset.

[0056] As a preferred embodiment of the present invention, the control mechanism controls the rotation of the transmission shaft 20 through the temperature of the inner cavity of the storage tank 2. The control mechanism includes a control cylinder 7, a sliding plug 21 and a control wheel 23. The control wheel 23 is fixedly mounted on the axial end of the transmission shaft 20. Rotating the transmission shaft 20 drives the control wheel 23 to rotate synchronously.

[0057] One end of the control tube 7 extends to the inner cavity of the storage tank 2, and the other end of the control tube 7 is provided with an exhaust hole. After the hot waste material passes into the storage tank 2, the temperature of one end of the control tube 7 rises.

[0058] The sliding plug 21 is slidably installed in the inner cavity of the control cylinder 7. The rotation of the control wheel 23 is controlled by the sliding of the sliding plug 21. Through the setting of the sliding plug 21, a closed space is formed in the control cylinder 7. When the control cylinder 7 is heated up, the gas inside the control cylinder 7 expands. At this time, the sliding plug 21 slides. After the waste material inside the storage tank 2 is discharged, the temperature inside the storage tank 2 decreases. At this time, the gas in the inner cavity of the control cylinder 7 contracts, thereby controlling the sliding plug 21 to reset.

[0059] Among them, the sliding of the sliding plug 21 is controlled by the temperature inside the storage tank 2, and cooperates with the elastic force of the torsion spring on the outer wall of the transmission shaft 20. When hot waste is input, the control wheel 23 is driven to rotate through the sliding plug 21. After the waste is discharged, the control wheel 23 is reset by the torsion spring, thereby achieving the cleaning of the cleaning scraper 16.

[0060] A connecting shaft 22 is fixedly installed at the bottom of the sliding plug 21. The connecting shaft 22 passes through the control cylinder 7, and a floating sealing plug is provided at the connection position. When the sliding plug 21 slides, the connecting shaft 22 is driven to rotate. At the same time, the setting of the connecting shaft 22 can effectively improve the sliding stability of the sliding plug 21.

[0061] A traction rope 15 is fixedly installed on the bottom surface of the connecting shaft 22, and the other end of the traction rope 15 extends to the inner cavity of the supporting cylinder 14 and is fixedly connected to the radial outer wall of the control wheel 23, so that when the sliding plug 21 slides upward, it drives the control wheel 23 to rotate, and then drives the transmission shaft 20 and the cleaning scraper 16 to rotate, so as to clean the filter plate 19. When the torsion spring drives the control wheel 23 to rotate, the traction rope 15 is reeled in through the control wheel 23.

[0062] As a preferred embodiment of the present invention, a connecting tube 12 is fixedly installed on the outer wall of the connecting cylinder 9, one end of the connecting tube 12 passes through the feed pipe 4 and is fixedly installed with a collecting box 13. By setting the connecting tube 12, when external waste passes through the filter plate 19, the impurities in the waste are controlled by water flow to flow back to the connecting tube 12, and then enter the inner cavity of the collecting box 13 through the connecting tube 12, thereby realizing the collection of impurities.

[0063] A guide plate 17 is fixedly installed on the inner wall of the connecting tube 9. The guide plate 17 is located on one side of the connecting tube 12 and is inclined toward the filter plate 19. When the waste flows, part of the waste hits the filter plate 19 to generate backflow. At this time, the impurities in the waste are guided into the interior of the connecting tube 12 through the setting of the guide plate 17, thereby improving the collection efficiency of the impurities.

[0064] An elastic sheet 18 is provided on the inner wall of the connecting tube 12, one end of the elastic sheet 18 is fixedly connected to the inner wall of the connecting tube 12, and a blocking bar is provided on the inner wall of the connecting tube 12 for preventing the elastic sheet 18 from lifting. By setting the blocking bar, the elastic sheet 18 can be controlled to rotate in one direction, thereby preventing impurities inside the collecting box 13 from flowing back into the inner cavity of the connecting tube 9 when the waste flows, thereby keeping the filter plate 19 clean.

[0065] As a preferred embodiment of the present invention, the circulation mechanism includes a control pump 5, a feed pipe 6 and a suction pipe 26. The control pump 5 is fixedly installed on the outer wall of the storage tank 2. The control pump 5 is a common water pump. One end of the feed pipe 6 is fixedly connected to the outer wall of the feed pipe 4, and the other end of the feed pipe 6 is connected to the output end of the control pump 5. When the control pump 5 absorbs the waste inside the storage tank 2, it is discharged into the inner cavity of the storage tank 2 through the feed pipe 4, thereby increasing the time that the hot waste stays in the storage tank 2. At the same time, the control pump 5 controls the circulation of the hot waste, which can realize the stirring of the waste in the storage tank 2, keep the waste in uniform contact with the feed pipe 11, and thereby improve the heat exchange efficiency.

[0066] One end of the extraction pipe 26 is connected to the bottom of the storage tank 2, and the other end of the extraction pipe 26 is connected to the input end of the control pump 5. The connection between the input end of the control pump 5 and the inner cavity of the storage tank 2 is achieved through the extraction pipe 26, so as to control the circulation flow of hot waste inside the storage tank 2.

[0067] A transfer tube 27 is fixedly mounted on the bottom surface of the storage tank 2 , and the bottom of the transfer tube 27 is fixedly connected to the extraction pipe 26 , wherein a cavity is provided inside the transfer tube 27 for achieving communication between the extraction pipe 26 and the inner cavity of the storage tank 2 .

[0068] A mounting frame 29 is fixedly mounted on the upper end surface of the adapter tube 27, and a mounting plate 28 is rotatably mounted on the inner wall of the mounting frame 29, wherein the mounting plate 28 is disc-shaped, and its axis coincides with the axial direction of the adapter tube 27, and an arc plate 30 is fixedly mounted on the bottom surface of the mounting plate 28. When the adapter tube 27 draws out the liquid inside the storage tank 2, the arc plate 30 is pushed by the liquid to drive the mounting plate 28 to rotate.

[0069] In order to improve the rotation stability of the mounting plate 28, a plurality of arc plates 30 are provided, and the plurality of arc plates 30 are evenly distributed along the axis of the adapter tube 27, so that when the adapter tube 27 sucks liquid, the mounting plate 28 is controlled to rotate stably, thereby disturbing the flow of waste in the storage tank 2 and keeping the material inside the storage tank 2 in uniform contact with the feed pipe 11.

[0070] A transmission rod 24 is fixedly mounted on the upper end surface of the mounting plate 28 . The transmission rod 24 is located at the center of the upper end of the mounting plate 28 . When the mounting plate 28 rotates, the transmission rod 24 is driven to rotate.

[0071] In order to improve the efficiency of disturbing the flow of waste materials inside the storage tank 2, a spoiler 25 is fixedly installed on the outer wall of the transmission rod 24. The spoiler 25 is distributed in a spiral shape along the outer wall of the transmission rod 24, thereby effectively improving the efficiency of disturbing the flow of waste materials inside the storage tank 2 and improving the heat exchange efficiency.
