Description

[0002] The heat storage device for flue molten salt waste heat recovery is a technical device for efficiently utilizing industrial flue gas waste heat. This device transfers the heat of high-temperature exhaust gas in the flue to molten salt, and then stores the molten salt as a heat energy carrier so that the heat can be released when needed.

[0003] The heat transfer between the high-temperature exhaust gas and the molten salt in the flue is mainly achieved by a heat exchanger. The existing heat exchangers are generally shell and tube heat exchangers, plate heat exchangers or sleeve heat exchangers. The main principle is to evenly divide the channels in the pipeline, one part is used for the flow of high-temperature flue gas, and the other part is used for the flow of molten salt. This design greatly reduces the flow channel of the high-temperature flue gas, which will cause serious obstruction to the flow of high-temperature flue gas, and may cause the high-temperature flue gas to accumulate in the flue and cause the air pressure in the flue to increase, resulting in safety hazards. Moreover, this design makes the molten salt only have a good heat recovery effect on the high-temperature flue gas near the inner wall of the channel, but it is difficult to recover the heat from the high-temperature flue gas in the middle of the channel, resulting in poor heat recovery effect of the overall device.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0037] Example 1 A heat storage device for recovering flue molten salt waste heat, such as Figure 1-Figure 5 As shown, it includes a mounting plate frame 11, a support ring 12, a buffer frame 13, a connecting pipe 14, a rotating blade 15, a first connector 16, a guide pipe 17, a storage box 18, a temperature-insulating shell 19 and a liquid pump 110. The flue pipe 1 is used to install the mounting plate frame 11. The mounting plate frame 11 has support rings 12 fixedly connected to both upper and lower sides. The middle of the support ring 12 is rotatably connected to the rotating blade 15. The rotating blade 15 is fixedly connected to the outside of the rotating blade 15. The upper and lower buffer frames 13 are fixedly connected and connected with five connecting pipes 14 equidistantly distributed on the circumference. The upper and lower buffer frames 13 are connected to each other. A first connector 16 is fixedly connected to the side of the support rings 12 that is away from each other. The first connector 16 is rotatably connected and communicated with the adjacent retention frame 13. A thermal insulation shell 19 is fixedly connected to the inside of the right side of the mounting plate frame 11. The upper and lower parts of the right side of the thermal insulation shell 19 are fixedly connected and communicated with a connecting valve port. A storage box 18 is fixedly connected to the inside of the thermal insulation shell 19. A flow guide pipe 17 is fixedly connected and communicated between the storage box 18 and the first connector 16. A liquid pump 110 is fixedly connected to the inside of the right side of the mounting plate frame 11. The liquid pump 110 is fixedly connected and communicated with the flow guide pipe 17 on the lower side.

[0038] When workers need to recover the waste heat in the high-temperature flue gas and store the heat, they can first install the mounting plate frame 11 and other components at the outlet of the flue pipe 1. At this time, the high-temperature flue gas ejected from the flue pipe 1 will contact the retention frame 13, and the hot oil stored in the retention frame 13 will absorb the heat in the high-temperature flue gas. At the same time, the high-temperature flue gas will also contact the rotor blades 15 and drive the rotor blades 15 and the retention frame 13 and other components to rotate. The rotation of the retention frame 13 and the hot oil inside can contact the high-temperature flue gas at various locations in the mounting plate frame 11 and recover the heat without causing large-scale obstruction to the flow of flue gas. In addition, the rotation of the rotor blades 15 driven by the flue gas can reduce the flow rate of the flue gas, so that the hot oil in the retention frame 13 can fully absorb the heat in the high-temperature flue gas, thereby improving the heat recovery efficiency. Then the liquid pump 110 can be started. 110 will cause the hot oil to circulate in the guide pipe 17, the first connector 16, the retention rack 13, the connecting pipe 14 and the storage box 18. When the high-temperature hot oil that has absorbed the heat of the flue gas enters the storage box 18, the molten salt between the storage box 18 and the insulation shell 19 will continuously absorb the heat of the high-temperature hot oil in the storage box 18 and gradually heat up or even melt, so that the heat collected by heat recovery can be stored in the molten salt. The insulation shell 19 has a good thermal insulation effect and can effectively reduce the loss of heat energy. When the workers need heat, the melted molten salt is discharged through the connecting valve port of the insulation shell 19 and transported to the heat-using equipment through the material pump, thereby transferring the stored heat to water or other media to meet the heat demand of production or life. When the flue pipe 1 no longer discharges flue gas, the liquid pump 110 can be turned off.

[0039] Example 2 On the basis of Example 1, Figure 6-Figure 9 As shown, it also includes a heat absorption mechanism, which is arranged on the support ring 12. The heat absorption mechanism includes a hollow bar frame 2, a second connector 21, a connecting pipe 2101, a connecting ring 22, a support frame 23 and a baffle block 24. The support frame 23 is fixedly connected to the top of the support ring 12 on the upper side, and the lower part of the support frame 23 is fixedly connected to the hollow bar frame 2. The outside of the hollow bar frame 2 is fixedly connected and connected to the connecting ring 22. The outside of the connecting ring 22 is rotatably connected to the second connector 21. The second connector 21 and the retention frame 13 are fixedly connected and connected to the connecting pipe 2101. The right side of the hollow bar frame 2 is fixedly connected to the inside of the baffle blocks 24 evenly distributed.

[0040] like Figure 6-Figure 8 As shown, the middle portion of the hollow bar frame 2 is composed of sixteen hollow heat absorbing plates, and the top of the hollow heat absorbing plate on the left side is designed to be inclined.

[0041] When the rotor blades 15 and the buffer frame 13 rotate under the impetus of the flue gas, the connecting pipe 2101 and the second connector 21 will also rotate with the buffer frame 13. Whenever the second connector 21 rotates until the connecting pipe 2101 is connected with the connecting ring 22, part of the hot oil in the lower buffer frame 13 will enter the connecting ring 22 and the hollow bar frame 2 through the connecting pipe 2101 and the second connector 21. The hot oil in the connecting ring 22 and the hollow bar frame 2 that has absorbed the heat of the flue gas will also enter the upper buffer frame 13 through the connecting pipe 2101 and the second connector 21 to participate in the circulation, so that intermittent Replace the hot oil in the hollow bar frame 2 and the connecting ring 22. At the same time, the hollow bar frame 2 has a large surface area, which can also enable the hot oil to fully absorb the heat of the high-temperature flue gas in the middle and realize heat recovery. The inclined design of the top left side of the hollow bar frame 2 can guide the flue gas to positively impact the blades of the rotor 15, so that the flue gas can better drive the rotor 15 and the retention frame 13 to rotate, and the baffle blocks 24 evenly distributed inside the right side of the hollow bar frame 2 will hinder the high-temperature flue gas, thereby extending the contact time between the high-temperature flue gas and the hollow bar frame 2, so that the hot oil in the hollow bar frame 2 can more fully absorb the heat in the high-temperature flue gas.

[0042] like Figure 10-12 As shown, it also includes a fixing mechanism, which is arranged on the mounting plate frame 11, and the fixing mechanism includes a threaded screw rod 3, a capstan block 31, a sealing cloth 32, a pressure block 33 and a pull rope 34. The three threaded screw rods 3 equidistantly distributed around the circumference are all threadedly connected to the lower part of the mounting plate frame 11, and the end of the threaded screw rod 3 close to the flue pipe 1 is fixedly connected to the capstan block 31, and the sealing cloth 32 is fixedly connected to the lower part of the mounting plate frame 11. The capstan block 31 and the sealing cloth 32 are squeezed together, and two upper and lower pull ropes 34 are fixedly connected between the three capstan blocks 31 equidistantly distributed around the circumference, and a pressure block 33 equidistantly distributed around the circumference is fixedly connected between the two upper and lower pull ropes 34, and the pressure block 33 and the sealing cloth 32 are squeezed together.

[0043] When workers need to install the mounting plate frame 11 and other components on the flue pipe 1, they can first put the mounting plate frame 11 on the air outlet of the flue pipe 1, and then rotate the four threaded screw rods 3 that are equidistantly distributed on the circumference in a positive direction, and the threaded screw rods 3 will then drive the capstan top block 31 to move inward while rotating, and the inward movement of the capstan top block 31 will contact and squeeze the sealing cloth 32, and the four corners of the sealing cloth 32 corresponding to the capstan top block 31 will then deform and fit tightly against the flue pipe 1, and the rotation of the capstan top block 31 will also reel in the draw rope 34, so that the pressing block 33 will also move inward and squeeze the sealing cloth 32, so that other parts of the sealing cloth 32 The four screw rods 3 are also tightly attached to the flue pipe 1, so that not only can the installation plate frame 11 be conveniently installed with the help of the winch top block 31 and the pressure block 33, but also the sealing cloth 32 can be used to fill the gap between the installation plate frame 11 and the flue pipe 1 to avoid leakage of high-temperature flue gas, thereby causing environmental pollution and safety risks. When workers need to disassemble the installation plate frame 11 and other components, they can simply rotate the four threaded screw rods 3 in the opposite direction. The threaded screw rods 3 and the winch top block 31 will move outward to reset while rotating in the opposite direction, and the pull rope 34 will also be loosened. At this time, the sealing cloth 32 will return to its original state under the action of its own elasticity and drive the pressure block 33 to move outward to reset.

[0044] like Fig.13 As shown, it also includes a gathering mechanism, which is arranged on the mounting plate frame 11. The gathering mechanism includes a collecting block 4 and an air guide frame 41. The collecting block 4 is fixedly connected to the lower part of the mounting plate frame 11, and the top of the collecting block 4 is fixedly connected and connected to the evenly distributed air guide frame 41.

[0045] like Fig.13 As shown, the air outlet on the upper part of the air guide frame 41 is designed to be oblique.

[0046] When the high-temperature flue gas is discharged from the flue pipe 1 and enters the mounting plate frame 11, the high-temperature flue gas will also pass through the collecting block 4 and enter the air guide frame 41. The collecting block 4 and the air guide frame 41 will first gather the high-temperature flue gas dispersed in the flue pipe 1, and then make the flue gas spray upward obliquely from the air guide frame 41 toward the lower side of the rotor blade 15, so that the thrust generated by the flue gas can be concentrated on the blades of the rotor blade 15, so that the rotor blade 15 and the retention frame 13 can be better driven to rotate with the help of the flue gas, so that the hot oil in the retention frame 13 can better recover the heat of the high-temperature flue gas at various locations inside the mounting plate frame 11.

[0047] like Figure 14-16 As shown, it also includes a vibration mechanism, which is arranged on the hollow bar frame 2. The vibration mechanism includes a shock-guide frame 5, a rotating shaft 51, a vibration spring piece 52 and a shifting block 53. The shock-guide frame 5 is fixedly connected to the lower part of the hollow bar frame 2. The middle part of the lower side of the shock-guide frame 5 is fixedly connected with vibration spring pieces 52 that are equidistantly distributed around the circumference. The top of the lower rotating blade 15 is fixedly connected with the rotating shaft 51. The upper part of the rotating shaft 51 is fixedly connected with the shifting block 53. The shifting block 53 is squeezed and matched with the vibration spring piece 52.

[0048] like Fig.15 and Fig.16 As shown, the outer side of the shift block 53 is provided with protrusions on both the front and rear sides.

[0049] When the smoke discharged from the flue pipe 1 passes through the hollow bar frame 2, the smoke contained in the smoke may adhere to the hollow bar frame 2, thereby affecting the heat transfer efficiency between the high-temperature smoke and the hot oil in the hollow bar frame 2, and even causing a partial blockage of the smoke passage of the hollow bar frame 2. When the rotating blade 15 rotates under the action of the smoke, the rotating shaft 51 and the shifting block 53 will also rotate with the rotating blade 15. When the shifting block 53 rotates until the surface protrusion contacts the adjacent vibrating spring piece 52, the surface protrusion of the shifting block 53 will squeeze the vibrating spring piece 52 and cause it to deform. When the surface protrusion is separated from the vibrating spring piece 52, the vibrating spring piece 52 will be deformed and restored to its original shape under the action of its own elasticity. When the shift block 53 rotates continuously with the rotating blade 15, the vibrating spring piece 52 will be deformed and restored to its original shape under the action of the shift block 53 and cause the vibration guide frame 5 and the hollow bar frame 2 and other components to vibrate, so that the smoke and dust adhering to the surface of the hollow bar frame 2 can be shaken off, and the shaken-off smoke and dust can continue to be discharged outward with the smoke, and the hollow bar frame 2 can be prevented from being partially blocked due to excessive smoke and dust adhering to it, and the heat transfer efficiency between the high-temperature smoke and the hot oil in the hollow bar frame 2 can be affected.

[0050] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
