Description

Technical Field

[0001] The invention belongs to the field of heat exchangers, in particular to a heat exchanger. Background Art

[0002] The main function of a heat exchanger is to achieve heat transfer and distribution. It can transfer heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process. The types of heat exchangers include partition heat exchangers, heat storage heat exchangers, and solid tube-sheet heat exchangers. The general principle of the solid tube-sheet heat exchanger is to allow the liquid cold material to enter the tube bundle of the heat exchanger, and then introduce the gas hot material into the heat exchanger. When both the gas hot material and the cold material are in the heat exchanger, a heat exchange process will occur. The gas hot material is liquefied inside the heat exchanger and then collected, while the liquid cold material is vaporized at high temperature and released from the inside of the heat exchanger, thereby completing the heat exchange work.

[0003] There are many types of heat exchangers, such as solid tube sheet heat exchangers and partition wall heat exchangers. In solid tube sheet heat exchangers, after heat exchange, the liquefied material will flow down layer by layer on the baffles set inside the heat exchanger. However, when it contains substances such as sulfuric acid and hydrogen chloride, the gas material will show a certain viscosity after being liquefied. When the viscosity is not large, the liquefied material is not easy to flow on the horizontally set baffles, which will cause some liquid materials to remain on the baffles, making it inconvenient for subsequent collection.

[0004] To this end, the present invention provides a heat exchanger. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a heat exchanger described in the present invention comprises a shell and an upper head and a lower head fixedly installed at the upper and lower ends of the shell, a cold material outlet is fixedly installed on one side of the upper head, a hot material inlet and a hot material outlet are fixedly installed on the outer side of the shell, a cold material inlet is fixedly installed on one side of the lower head, a heat exchange component is fixedly installed inside the shell, the heat exchange component comprises a plurality of tube bundles and a plurality of baffle components installed inside the shell, a plurality of the baffle components are fixedly connected to the inner wall of the shell, a plurality of the tube bundles are fixedly installed with tube sheets at the upper and lower ends, and a plurality of the lower ends of the tube bundles are fixedly installed with fixed anti-collision plates at the outer sides;

[0007] The deflector assembly includes a deflector baffle and an inclined baffle fixedly installed at the lower end of the deflector baffle, the inclined baffle is inclined, a plurality of leakage grooves and a first fixed groove are penetrated on the deflector baffle, and a plurality of second fixed grooves are penetrated on the inclined baffle.

[0008] Preferably, the plurality of leakage grooves are located directly above the corresponding inclined baffles, and the inner walls of the plurality of first fixed grooves and second fixed grooves are in contact with the outer side of the tube bundle.

[0009] Preferably, an anti-impact component is installed directly below the tube sheet, the anti-impact component is located at the upper end of the plurality of tube bundles, and the anti-impact component is at the same level as the hot material inlet.

[0010] Preferably, the anti-collision assembly comprises a fixing ring fixedly mounted on the upper ends of the plurality of tube bundles, and a rotating anti-collision plate is movably mounted on the outer side of the fixing ring.

[0011] Preferably, a rotation groove is provided inside the fixing ring, and annular grooves are provided above and below the rotation groove.

[0012] Preferably, the rotating anti-collision plate comprises a rotating ring movably mounted inside the rotating groove, a plurality of ear strips are fixedly mounted on the outer side of the rotating ring, and a plurality of air-permeable grooves are penetrated through the interior of the ear strips.

[0013] Preferably, a plurality of balls are movably mounted on the upper and lower sides of the rotating ring, and the plurality of balls are located inside the annular groove.

[0014] Preferably, an air inlet groove is provided inside the hot material inlet, and an air flow baffle is fixedly installed on the air inlet groove toward the inside of the anti-impact component.

[0015] Preferably, a plurality of air inlet holes are formed through the interior of the air flow baffle, and the air flow baffle is arranged in an arc shape.

[0016] Preferably, the air inlet groove comprises a vertical air groove and an oblique air groove fixedly opened inside the hot material inlet, and the vertical air groove and the oblique air groove are connected.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In a heat exchanger described in the present invention, when a small amount of viscous liquid material is retained on the upper side of the baffle plate, it will leak to the upper side of the inclined baffle plate through the leakage groove. Because of the inclined setting of the upper side of the inclined baffle plate, the viscous liquid retained on the baffle plate will flow to the next baffle assembly through the inclined baffle plate, and the liquid impacted from the inclined part of the inclined baffle plate will act on the upper side of the next group of baffle plates, generating an impact force on the contact position between the baffle plate and the inner wall of the shell, impacting away the viscous liquid on the surface of the baffle plate, and further preventing the viscous liquid from being retained inside the shell.

[0019] 2. A heat exchanger described in the present invention feeds gas materials from the position of the hot material inlet. The gas continuously enters the shell and acts on multiple tube bundles continuously. When the gas material contains substances such as sulfuric acid and hydrogen chloride, it directly acts on the multiple tube bundles and corrodes them. At this time, an anti-impact component is provided at the same position as the hot material inlet. The gas will first act on the anti-impact component to avoid the gas material impacting and quickly corroding the tube bundles.

[0020] 3. The heat exchanger described in the present invention directly acts on the rotating ring when the gas material is fed from the hot material inlet. When the gas material generates impact force on the ear bar, it drives the rotating ring to rotate inside the rotating groove. As the rotating ring has rotation inertia and the hot material inlet is continuously fed, the rotating ring will continue to rotate, allowing the gas material to evenly act on the outside of the rotating ring, avoiding the gas material from always impacting only one position of the rotating ring. Because when the gas material has a certain corrosiveness, it will quickly damage the rotating ring and cause damage to multiple tube bundles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1

[0034] like Figure 1-5 As shown, a heat exchanger according to an embodiment of the present invention comprises a shell 2 and an upper head 3 and a lower head 1 fixedly mounted at the upper and lower ends of the shell 2, a cold material outlet 31 is fixedly mounted on one side of the upper head 3, a hot material inlet 21 and a hot material outlet 22 are fixedly mounted on the outer side of the shell 2, a cold material inlet 11 is fixedly mounted on one side of the lower head 1, a heat exchange component 4 is fixedly mounted inside the shell 2, the heat exchange component 4 comprises a plurality of tube bundles 6 and a plurality of baffle components 8 mounted inside the shell 2, the plurality of baffle components 8 are fixedly connected to the inner wall of the shell 2, a plurality of tube bundles 6 are fixedly mounted with tube sheets 5 at the upper and lower ends, and a plurality of fixed anti-collision plates 9 are fixedly mounted on the outer sides of the lower ends of the plurality of tube bundles 6;

[0035] The deflector assembly 8 includes a deflector baffle 81 and an inclined baffle 82 fixedly installed at the lower end of the deflector baffle 81. The inclined baffle 82 is inclined. The deflector baffle 81 is provided with a plurality of leakage grooves 811 and a first fixed groove 812. The inclined baffle 82 is provided with a plurality of second fixed grooves 821.

[0036] Specifically, when the heat exchanger needs to work, first, liquid cold material is fed through the cold material inlet 11. After the liquid enters the lower head 1, it is allowed to enter the multiple tube bundles 6 in an accumulation manner, so that the multiple tube bundles 6 are in a low-temperature state. At this time, the high-temperature gas material is allowed to enter the shell 2 through the hot material inlet 21. The high-temperature gas material exchanges heat with the liquid material inside the tube bundle 6. At this time, the gas material is liquefied and flows downward through the baffle assembly 8, and the liquid material is vaporized inside the tube bundle 6. The vaporized cold material enters the upper head 3 and is finally released through the cold material outlet 31. When the gas material contains substances such as sulfuric acid and hydrogen chloride, the gas material will have a certain viscosity after being liquefied, which makes it difficult for the viscous liquefied material to flow down from the baffle assembly 8. In this device, the baffle The flow component 8 is not only provided with a deflection baffle 81, because when a small amount of viscous liquid material flows downward on the deflection baffle 81, the liquid material will be retained on the deflection baffle 81 due to the horizontal setting of the deflection baffle 81, and it is not easy to collect. In the present device, when a small amount of viscous liquid material is retained on the upper side of the deflection baffle 81, it will leak to the upper side of the inclined baffle 82 through the leakage groove 811. Because of the inclined setting of the upper side of the inclined baffle 82, the viscous liquid retained on the deflection baffle 81 will flow through the inclined baffle 82 to the next deflection component 8, and the liquid impacting from the inclined part of the inclined baffle 82 will act on the upper side of the next group of deflection baffles 81, generating an impact force on the contact position between the deflection baffle 81 and the inner wall of the shell 2, and impacting the viscous liquid on the surface of the deflection baffle 81, further preventing the viscous liquid from being retained inside the shell 2.

[0037] like Figure 5 As shown, the plurality of liquid leakage grooves 811 are located directly above the corresponding inclined baffles 82 , and the inner walls of the plurality of first fixed grooves 812 and second fixed grooves 821 are in contact with the outer side of the tube bundle 6 .

[0038] Specifically, the inclined baffle 82 and the deflector baffle 81 are fixedly connected to the multiple tube bundles 6. When the gas material liquefies and descends from the inside of the shell 2, the high-temperature gasified material and even the liquefied material will not enter the multiple tube bundles 6 through the cooperation of the multiple deflector baffles 81 and the inclined baffle 82.

[0039] like Figure 6 As shown, an anti-impact assembly 7 is installed directly below the tube sheet 5 , the anti-impact assembly 7 is located at the upper end of the plurality of tube bundles 6 , and the anti-impact assembly 7 is at the same level as the hot material inlet 21 .

[0040] Specifically, the gas material is fed from the position of the hot material inlet 21, and the gas continuously enters the interior of the shell 2, and will continuously act on the multiple tube bundles 6. When the gas material contains substances such as sulfuric acid and hydrogen chloride, it will directly act on the multiple tube bundles 6 to corrode them. At this time, an anti-impact component 7 is arranged at a position flush with the hot material inlet 21, and the gas will first act on the anti-impact component 7 to prevent the gas material from impacting and quickly corroding the tube bundle 6.

[0041] like Figure 6-7 As shown, the anti-collision assembly 7 includes a fixed ring 71 fixedly installed on the upper ends of multiple tube bundles 6, a rotating anti-collision plate 72 is movably installed on the outer side of the fixed ring 71, a rotating groove 711 is opened inside the fixed ring 71, and annular grooves 712 are opened at the upper and lower positions of the rotating groove 711. The rotating anti-collision plate 72 includes a rotating ring 721 movably installed inside the rotating groove 711, a plurality of ear strips 722 are fixedly installed on the outer side of the rotating ring 721, and a plurality of air permeable grooves 723 are opened inside the ear strips 722.

[0042] Specifically, when the gas material is fed from the hot material inlet 21, it will directly act on the rotating ring 721. When the gas material generates an impact force on the ear bar 722, it will drive the rotating ring 721 to rotate inside the rotating groove 711. As the rotating ring 721 has the inertia of rotation and the hot material inlet 21 is continuously fed, the rotating ring 721 will continue to rotate, allowing the gas material to evenly act on the outside of the rotating ring 721, avoiding the gas material from always impacting only one position of the rotating ring 721. Because when the gas material has a certain corrosiveness, it will quickly damage the rotating ring 721, and then cause damage to multiple tube bundles 6.

[0043] like Figure 7 As shown, a plurality of round balls 724 are movably mounted on the upper and lower sides of the rotating ring 721 , and the plurality of round balls 724 are located inside the annular groove 712 .

[0044] Specifically, the rotating ring 721 rotates inside the rotating groove 711 by rolling a plurality of balls 724 inside the annular groove 712 , thereby reducing the sliding friction between the rotating ring 721 and the fixed ring 71 , and reducing the damage between the fixed ring 71 and the rotating anti-collision plate 72 .

[0045] Embodiment 2

[0046] like Figure 8-9As shown, comparative example 1, wherein another implementation of the present invention is: an air inlet groove 211 is opened through the interior of the hot material inlet 21, an air flow baffle 212 is fixedly installed on the interior of the air inlet groove 211 toward the anti-collision component 7, a plurality of air inlet holes 2121 are opened through the interior of the air flow baffle 212, the air flow baffle 212 is arranged in an arc-shaped state, the air inlet groove 211 includes a vertical air groove 2111 and an oblique air groove 2112 fixedly opened in the hot material inlet 21, and the vertical air groove 2111 and the oblique air groove 2112 are communicated with each other.

[0047] Specifically, the gas material enters the oblique gas groove 2112 through the vertical gas groove 2111. The oblique gas groove 2112 is inclined toward the ear strip 722 and the rotating ring 721. Therefore, when the gas material impacts the rotating anti-collision plate 72 through the oblique gas groove 2112, it is equivalent to acting on the circumferential outer section of the rotating ring 721, that is, the gas material impacts the rotating ring 721 obliquely. In this way, the feed amount at the hot material inlet 21 will not be reduced, and the effect of driving the rotating ring 721 to rotate will be better. An air flow baffle 212 is fixedly installed inside the air inlet groove 211. When the gas is transported out of the vertical gas groove 2111, part of the gas passes through the vertical gas groove 2111 without obstruction. The gas passes through the straight gas groove 2111, and part of the gas passes through the air inlet 2121 from the inside of the air flow baffle 212. Because the feed amount cannot be reduced, the apertures of the vertical gas groove 2111 and the oblique gas groove 2112 cannot be reduced. However, such a feed amount will cause the diameter of the gas impacting the rotating anti-collision plate 72 to be larger, which will impact the inner wall of the shell 2. Therefore, the gas passing through the unobstructed vertical gas groove 2111 will act on the rotating ring 721 at the oblique section to make it rotate, and the gas material passing through the air flow baffle 212 will have its impact force relieved, so that when this part of the gas acts on the inner wall of the shell 2, there will be no problem of damage to the inner wall of the shell 2 caused by the impact force.

[0048] Working principle: When the heat exchanger needs to work, firstly, the liquid cold material is fed through the cold material inlet 11. After the liquid enters the lower head 1, it is allowed to enter the multiple tube bundles 6 in an accumulation manner, so that the multiple tube bundles 6 are in a low temperature state. At this time, the high-temperature gas material is allowed to enter the shell 2 through the hot material inlet 21. The high-temperature gas material exchanges heat with the liquid material in the tube bundle 6. At this time, the gas material is liquefied and flows downward through the baffle assembly 8, while the liquid material is vaporized inside the tube bundle 6. The vaporized cold material enters the upper head 3. , and finally released through the cold material outlet 31. When the gas material contains substances such as sulfuric acid and hydrogen chloride, the gas material will show a certain viscosity after being liquefied, which makes it difficult for the viscous liquefied material to flow down from the baffle assembly 8. In this device, the baffle assembly 8 is not only provided with a baffle baffle 81, because when a small amount of viscous liquid material flows down on the baffle baffle 81, the horizontal setting of the baffle baffle 81 will cause the liquid material to be retained on the baffle baffle 81, which is not easy to collect. In this device, when a small amount of viscous liquid material is retained on the baffle baffle 8 1, it will leak to the upper side of the inclined baffle 82 through the leakage groove 811. Because the upper side of the inclined baffle 82 is inclined, the viscous liquid retained on the baffle 81 will flow to the next baffle assembly 8 through the inclined baffle 82, and the liquid impacted from the inclined part of the inclined baffle 82 will act on the upper side of the next group of baffle baffles 81, generating an impact force on the contact position between the baffle baffle 81 and the inner wall of the shell 2, impacting the viscous liquid on the surface of the baffle baffle 81, further preventing the viscous liquid from being retained in the interior of the shell 2, and the gas material from the hot material inlet 21. When feeding, it will directly act on the rotating ring 721. When the gas material generates impact force on the ear bar 722, it will drive the rotating ring 721 to rotate inside the rotating groove 711. As the rotating ring 721 has the inertia of rotation and the hot material inlet 21 is continuously fed, the rotating ring 721 will continue to rotate, allowing the gas material to evenly act on the outside of the rotating ring 721, avoiding the gas material from always impacting only one position of the rotating ring 721. Because when the gas material has a certain corrosiveness, it will quickly damage the rotating ring 721, and then cause damage to multiple tube bundles 6.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
