Description
Technical Field
The embodiment of the application relates to the technical field of evaporator equipment, in particular to a jacketed thin film evaporator.
Background
The existing jacketed thin film evaporator mainly comprises an integral type thin film evaporator and a semi-tubular type thin film evaporator. The thin film evaporator with the half-tube jacket mostly adopts a mode that the half tube and the cylinder are mutually fixed. Specifically, the cylinder is of a cylindrical structure, the half pipe is wound on the cylinder, two side edges of the half pipe are welded and fixed on the outer wall surface of the cylinder, and a channel for circulating heating fluid is formed by utilizing the outer wall surfaces of the half pipe and the cylinder, so that the jacketed evaporator is formed.
When the jacketed evaporator is used, high-temperature and high-pressure fluid is injected into a channel which is formed by the half pipe and the outer wall surface of the cylinder body and is used for circulating heating fluid, so that the temperature of the inner wall surface of the cylinder body is increased, and materials positioned in the cylinder body are heated and evaporated, thereby realizing the process requirement.
However, when the conventional jacketed evaporator is used, when high-temperature and high-pressure fluid is injected into a channel for circulating the heating fluid, which is formed by the half pipe and the outer wall surface of the cylinder, the channel for circulating the heating fluid, which is formed by the half pipe and the outer wall surface of the cylinder, is easily broken, so that the jacketed evaporator is damaged.
Accordingly, it is desirable to provide a jacketed thin film evaporator that reduces the probability of damage to the jacketed thin film evaporator when high temperature and high pressure fluid is injected into the passageway of the jacketed thin film evaporator for injecting heating fluid.

According to the jacketed thin film evaporator provided by the embodiment of the application, as the first bulge is the bulge protruding from the outer wall surface of the cylindrical body (namely, the first bulge and the cylindrical body are integrally formed), the structural strength of the joint of the first bulge and the outer wall surface of the cylindrical body is high; since the junction between the portion of the wall surface of the first passage other than the outer wall surface of the cylindrical body and the outer wall surface of the cylindrical body is the junction between the first projection and the outer wall surface of the cylindrical body, the structural strength is high based on the junction between the first projection and the outer wall surface of the cylindrical body, so that the structural strength is high at the junction between the portion of the wall surface of the first passage other than the outer wall surface of the cylindrical body and the outer wall surface of the cylindrical body. Thus, when the high-temperature and high-pressure fluid is injected into the channel (namely the first channel for circulating the heating fluid, which is formed by the first half pipe and the second half pipe in a surrounding manner) of the jacket type thin film evaporator, the possibility of cracking the wall surface of the channel (namely the first channel) for circulating the heating fluid can be reduced, and the damage probability of the jacket type thin film evaporator is further reduced.

Detailed Description
As known from the background art, when the conventional jacketed thin-film evaporator is used, when high-temperature and high-pressure fluid is injected into a channel for circulating heating fluid formed by the half pipe and the outer wall surface of the cylinder, the channel for circulating heating fluid formed by the half pipe and the outer wall surface of the cylinder is easily broken, so that the jacketed thin-film evaporator is damaged.
The inventors of the present application have found through intensive studies that, when a high-temperature and high-pressure fluid is injected into a passage for circulating a heating fluid, which is formed by a half pipe and an outer wall surface of a cylindrical body, a stress value at a joint between a portion of the wall surface of the passage excluding the outer wall surface of the cylindrical body and the outer wall surface of the cylindrical body is maximized.
The conventional half-tube jacketed thin film evaporator is formed by mutually fixing a half tube and a cylinder, namely the cylinder is of a cylindrical structure, the half tube is wound on the cylinder, two side edges of the half tube are welded and fixed on the outer wall surface of the cylinder, and a channel for circulating heating fluid is formed by utilizing the outer wall surfaces of the half tube and the cylinder, so that the jacketed thin film evaporator is formed.
In this way, the joint between the portion of the wall surface of the channel excluding the outer wall surface of the tubular body and the outer wall surface of the tubular body is a joint between the half pipe and the tubular body, and since the half pipe and the tubular body are fixed to each other by welding, the structural strength of the joint between the half pipe and the tubular body is small, and therefore the structural strength of the joint between the portion of the wall surface of the channel excluding the outer wall surface of the tubular body and the outer wall surface of the tubular body is small. Therefore, when the high-temperature and high-pressure fluid is injected into the channel which is formed by the half pipe and the outer wall surface of the cylinder body and is used for circulating the heating fluid, the channel is easy to break, so that the jacket type thin film evaporator is damaged.
Based on this, in order to reduce the probability of damage to the jacketed thin film evaporator when injecting a fluid of high temperature and high pressure into a passage for injecting a heating fluid of the jacketed thin film evaporator, the present inventors devised a jacketed thin film evaporator comprising: the cylinder is provided with a cylinder body and two first bulges protruding from the outer wall surface of the cylinder body, a space is reserved between the two first bulges, and the two first bulges and a part of the cylinder body positioned between the two first bulges jointly form a first half pipe; and the second half pipe and the first half pipe jointly enclose a first channel for circulating heating fluid, wherein the second half pipe is fixed with the two first bulges.
In the jacketed thin film evaporator designed by the inventor of the application, as the first bulge is a bulge protruding from the outer wall surface of the cylindrical body (namely, the first bulge and the cylindrical body are integrally formed), the structural strength of the joint of the first bulge and the outer wall surface of the cylindrical body is larger; since the junction between the portion of the wall surface of the first passage other than the outer wall surface of the cylindrical body and the outer wall surface of the cylindrical body is the junction between the first projection and the outer wall surface of the cylindrical body, the structural strength is high based on the junction between the first projection and the outer wall surface of the cylindrical body, so that the structural strength is high at the junction between the portion of the wall surface of the first passage other than the outer wall surface of the cylindrical body and the outer wall surface of the cylindrical body.
Thus, when the high-temperature and high-pressure fluid is injected into the channel (namely the first channel for circulating the fluid, which is formed by the first half pipe and the second half pipe in a surrounding way) for injecting the heating fluid of the jacketed thin film evaporator, the possibility of cracking the wall surface of the channel (namely the first channel) for circulating the heating fluid can be reduced, and the damage probability of the jacketed thin film evaporator is further reduced.
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of each embodiment of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical means claimed in the present application can be realized based on various changes and modifications of the following embodiments.
Referring to fig. 1, some embodiments of the present application provide a jacketed thin film evaporator, comprising: a cylinder 110 having a cylinder body 111 and two first protrusions 112 protruding from an outer wall surface of the cylinder body 111 with a space between the two first protrusions 112, the two first protrusions 112 and a portion of the cylinder body 111 located between the two first protrusions 112 together forming a first half pipe; the second half pipe 120 encloses together with the first half pipe a first channel 130 for the flow of fluid, wherein the second half pipe 120 is fixed to the two first projections 112.
In some embodiments, the two first protrusions 112 extend along the outer wall surface of the cylindrical body 111, and the extending directions of the two first protrusions 112 are parallel to each other, and the protruding direction of any one first protrusion 112 is perpendicular to the extending direction of the first protrusion 112. Further, the two first protrusions 112 are oppositely disposed in a direction perpendicular to the extending direction of the first protrusions 112.
In some embodiments, the second half pipe 120 has two end surfaces disposed opposite to each other in the extending direction thereof, and a first side surface, an outer wall surface, a second side surface, and an inner wall surface connected to both end surfaces, wherein the first side surface, the outer wall surface, the second side surface, and the inner wall surface are connected in order from end to end; the outer surface of one of the two first protrusions 112, which is far from the cylindrical body 111, is attached and fixed to the first side surface, and the outer surface of the other of the two first protrusions 112, which is far from the cylindrical body 111, is attached and fixed to the second side surface.
In this way, when the second half pipe 120 is fixed to the two first protrusions 112, the second half pipe 120 and the first half pipe may be enclosed together to form the first channel 130 for fluid communication. And the cross-sectional area of the first channel 130 defined by the second half pipe 120 and the first half pipe is larger without changing the sizes of the first half pipe and the second half pipe 120.
In still other embodiments, the portion of the outer wall surface of the second half pipe 120 adjacent to the first side is fitted and fixed with the side surface of one of the first protrusions 112, and the portion of the outer wall surface of the second half pipe 120 adjacent to the second side is fitted and fixed with the side surface of one of the first protrusions 112, and at this time, the second half pipe 120 is located between the two first protrusions 112. In this way, when the second half pipe 120 is fixed to the two first projections 112, the second half pipe 120 and the first half pipe can be enclosed together to form the first passage 130 for fluid communication.
In still other embodiments, a portion of the inner wall surface of the second half pipe 120 adjacent to the first side surface is abutted and fixed with a side surface of one of the first protrusions 112, and a portion of the inner wall surface of the second half pipe 120 adjacent to the second side surface is abutted and fixed with a side surface of one of the first protrusions 112, and at least a portion of the two first protrusions 112 are located within the second half pipe 120. In this way, when the second half pipe 120 is fixed to the two first protrusions 112, the second half pipe 120 and the first half pipe may be enclosed together to form the first channel 130 for fluid communication.
It should be noted that, the present application is not limited to the specific embodiment for fixing the second half pipe 120 to the two first protrusions 112. In one example, the second half-tube 120 is welded to the two first protrusions 112.
In some embodiments, the first half pipe has a wall thickness greater than the wall thickness of the second half pipe 120 at the location where the two first protrusions 112 are located. In this way, the structural strength of the wall surface of the first channel 130 at the connection point between the portion of the wall surface of the first channel 130 except the outer wall surface of the cylindrical body 111 and the outer wall surface of the cylindrical body 111 (i.e. the connection point between the first protrusion 112 and the cylindrical body 111) is relatively high, so that the possibility of cracking the wall surface of the first channel 130 for circulating fluid is further reduced, and the probability of damaging the jacketed thin film evaporator is further reduced.
In some embodiments, the wall thickness of the first half tube is greater throughout than the wall thickness of the second half tube 120. In this way, the structural strength of the wall surface of the first channel 130 at the connection point between the portion except the outer wall surface of the cylindrical body 111 and the outer wall surface of the cylindrical body 111 (i.e. the connection point between the first protrusion 112 and the cylindrical body 111) is further increased, so that the possibility of cracking the wall surface of the first channel 130 for circulating fluid is further reduced, and the probability of damaging the jacketed thin film evaporator is further reduced.
In some embodiments, the jacketed thin film evaporator further comprises: a second passage 140 provided on an outer wall surface of the tubular body 111; the first channel 130 communicates with the second channel 140.
In some embodiments, one end of the second channel 140 is fixed with one of the two first protrusions 112; the first protrusion 112 fixed to the second channel 140 has a through hole 113 at a position facing the second channel 140; the second passage 140 communicates with the first passage 130 via the through hole 113.
In this way, when the first channel 130 is communicated with the second channel 140, the second half pipe 120 does not need to be mutually attached and fixed with the second channel 140, so that the structural strength at the joint of the first channel 130 and the second channel 140 is larger.
In some embodiments, the first channel 130 circumferentially surrounds the cylindrical body 111 along the cylindrical body 111; the extending direction of the second channels 140 is the same as the axial direction of the cylindrical body 111, the number of the second channels 140 is a plurality, and the plurality of second channels 140 are sequentially arranged at intervals along the circumferential direction of the cylindrical body 111.
In some embodiments, the number of first channels 130 is two, and the two first channels 130 are disposed opposite to each other in the extending direction of the second channel 140.
In some embodiments, one of the two first channels 130 is provided with a medium inflow opening and the other is provided with a medium outflow opening. In this way, the contact time of the fluid flowing into the first and second channels 130 and 140 with the cylindrical body 111 can be made longer, so that the temperature of the jacketed evaporator can be raised better, thereby increasing the temperature in the cylindrical body 111 faster.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of implementing the present application and that various changes in form and details may be made therein without departing from the spirit and scope of the present application. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model, and the scope of the utility model shall be defined by the appended claims.
