Description

Technical Field

[0001] This application belongs to the field of polymerization reaction equipment technology, specifically relating to a reaction apparatus. Background Technology

[0002] A reaction vessel is a container used for chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. For some reactions, such as polymerization, a stirring paddle is installed inside the reaction vessel to improve reaction efficiency.

[0003] For stirred tank reactors used in polymerization reactions, due to the mechanism and method of polymerization, solid precipitates and gels are prone to adhere to the reactor walls and agitator during the reaction. As the amount of precipitates and gels increases, the heat transfer efficiency deteriorates, which in turn affects the polymerization reaction, such as causing safety issues like explosive polymerization or substandard product quality. Utility Model Content

[0004] Based on the above problems, it is necessary to provide a reaction device that can clean the reactor and prevent excessive deposits and gels inside from affecting the polymerization reaction.

[0016] Furthermore, the spray ball is rotatably connected to the connecting pipe about a vertical axis, and the spray ball has a turbine structure inside to drive the spray ball to rotate when the telescopic assembly inputs cleaning fluid into the spray ball.

[0017] Furthermore, the reaction device also includes a connector connected to the connecting pipe; the spray ball includes a connecting part and a ball connected to each other, the connecting part is rotatably connected to the connector about a vertical axis, and a turbine structure is provided inside the ball.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Existing reactors used for polymerization reactions are prone to the accumulation of precipitates and gels on the inner walls and agitators, affecting the polymerization reaction efficiency. To address this issue, this application provides a reaction apparatus equipped with a structure for cleaning the reactor. This allows for cleaning of the reactor interior after a period of use to remove precipitates and gels, thus preventing their deposition.

[0030] like Figure 1As shown, in one embodiment, the reaction apparatus includes a reaction vessel 110, a telescopic assembly 120, a spray ball 130, and a liquid supply assembly 140. The telescopic assembly 120 is disposed within the reaction vessel 110, with its telescopic end extending into the reaction vessel 110 and capable of reciprocating vertically. The spray ball 130 is connected to the telescopic end and is capable of rotating around a vertical axis. The liquid supply assembly 140 is connected to the telescopic assembly 120 to deliver cleaning liquid to the spray ball 130, which then sprays the cleaning liquid into the reaction vessel 110, thus cleaning the reaction vessel 110. The telescopic assembly 120 can move linearly, thereby adjusting the position of the spray ball 130 within the reaction vessel 110. Simultaneously, the spray ball 130's ability to rotate around a vertical axis allows for cleaning of various locations within the reaction vessel 110, improving the cleaning effect.

[0031] Furthermore, the reaction apparatus also includes a recovery component 150, which is connected to the reaction vessel 110 and the liquid supply component 140 to recover the cleaning liquid and transport the recovered cleaning liquid to the liquid supply component 140, thereby reducing the consumption of cleaning liquid and reducing cleaning costs.

[0032] Using the above-described reaction apparatus, after a period of use, the reaction vessel 110 receives cleaning fluid via the liquid supply assembly 140 into the spray ball 130. The cleaning fluid is sprayed from the spray ball 130 into the reaction vessel 110, thereby cleaning the interior of the reaction vessel 110. During the cleaning process, the spray ball 130 can reciprocate vertically and rotate around its vertical axis, thus improving the cleaning effect. Simultaneously, the cleaning fluid can be recovered via the recovery assembly 150 and returned to the liquid supply assembly 140 for reuse, thereby reducing cleaning fluid consumption and lowering cleaning costs.

[0033] It should be noted that the spray ball 130 has a spray chamber, and the telescopic component 120 is connected to the spray chamber of the spray ball 130; the side wall of the spray ball 130 has multiple spray holes spaced apart, and the spray holes are connected to the spray chamber, so that cleaning liquid is sprayed around the spray ball 130 through the spray holes. Combined with lifting and rotation, this ensures comprehensive cleaning of the interior of the reactor 110. Specifically... Figure 1 In the embodiment shown, the spray ball 130 includes a connecting part 131 and a ball 132 that are connected to each other. The connecting part 131 is connected to the telescopic end of the telescopic component 120, and the ball 132 has a spray chamber and spray holes.

[0034] In one embodiment, the liquid supply assembly 140 includes a storage tank 141 and a delivery pump 142. The storage tank 141 stores the cleaning fluid, and is connected to a telescopic assembly 120 via the delivery pump 142. The delivery pump 142 pumps the cleaning fluid from the storage tank 141 to the telescopic assembly 120, and then the fluid is fed into the spray ball 130 via the telescopic assembly 120. Further, a recovery assembly 150 is connected to the storage tank 141 to transport the recovered cleaning fluid back to the storage tank 141 for reuse.

[0035] In one embodiment, the telescopic component 120 includes an installation pipe 121 and a connecting pipe 122. The installation pipe 121 is connected to and communicates with the interior of the reactor 110. The connecting pipe 122 is reciprocally inserted into the installation pipe 121 along its length, and one end of the connecting pipe 122 extends into the reactor 110 to connect with the spray ball 130, thereby driving the spray ball 130 to reciprocate. Thus, the telescopic end is the end of the connecting pipe 122 that extends into the reactor 110. The end of the connecting pipe 122 away from the spray ball 130 extends out from the installation pipe 121, and the liquid supply component 140 is connected to this end.

[0036] In Embodiment 1, the connecting pipe 122 is also rotatable about a vertical axis, and the spray ball 130 is fixed relative to the connecting pipe 122. Preferably, the connecting pipe 122 is threaded to the mounting pipe 121, and the connecting pipe 122 and the spray ball 130 are welded together or fixed together by a threaded connection. Specifically, the bottom end of the connecting pipe 122 can be welded to the connecting part 131 or threaded together. In this way, by rotating the connecting pipe 122, the connecting pipe 122 can be moved back and forth along the length of the mounting pipe 121, thereby driving the spray ball 130 to move in a straight line while simultaneously rotating the spray ball 130, thus further enabling all-round spraying inside the reactor 110 and improving the spraying effect.

[0037] In embodiment 2, the spray ball 130 is rotatably connected to the pipe 122 about a vertical axis, and when the telescopic component inputs cleaning fluid into the spray ball 130, the spray ball 130 can rotate under the action of the cleaning fluid.

[0038] In order to make the spray ball 130 rotate under the action of the cleaning fluid, a turbine structure can be set inside the spray ball 130, specifically a turbine structure inside the ball 132, so as to drive the spray ball 130 to rotate when the telescopic component 120 inputs the cleaning fluid into the spray ball 130; or spray holes can be spaced horizontally circumferentially on the side wall of the ball 132, with the extension direction of the spray holes inclined in the same direction relative to the horizontal radial direction of the ball 132, so that the cleaning fluid can provide the driving force for the rotation of the ball 132 when it is sprayed out from the spray holes.

[0039] It should be noted that the turbine structure described above is a conventional turbine rotor structure, which is fixedly connected to the ball 132. When the cleaning fluid flows through the turbine structure, it drives the turbine structure to rotate, thereby causing the spray ball 130 to rotate. In addition, the following description of Embodiment 2 uses the example of a turbine structure installed inside the ball 132.

[0040] In this embodiment, the connecting pipe 122 can reciprocate only in the vertical direction. At this time, the connecting pipe 122 can be connected to the mounting pipe 121 by a structure such as a sealing ring. While ensuring the sealing performance, the connecting pipe 122 can reciprocate in the vertical direction under the action of external force. Moreover, the damping provided by the sealing ring can ensure that the connecting pipe 122 is prevented from moving during the cleaning process.

[0041] Furthermore, the reaction apparatus also includes a connector, which is connected to the connecting pipe 122; a connecting part 131 is rotatably connected to the connector about a vertical axis, and a turbine structure is provided inside the sphere 132. In practical applications, the connector is cylindrical, with the end of the connecting part 131 away from the sphere 132 extending into the connector and making sealed contact with the interior of the connector, allowing the connecting part 131 to rotate relative to the connector; the connector is threadedly connected to the connecting pipe 122. It should be noted that the rotatable connection between the connecting part 131 and the connector is a conventional structure, such as an existing rotary joint, which will not be described in detail here.

[0042] In one embodiment, the top of the reactor 110 has an installation port, and the installation pipe 121 is installed on the top of the reactor 110 and communicates with the installation port. The connecting pipe 122 passes through the installation pipe 121, and the bottom end (telescopic end) of the connecting pipe 122 can extend into the reactor 110 through the installation port.

[0043] In one embodiment, the reaction vessel 110 includes a vessel body 111 and a stirring structure 112. The stirring structure 112 is disposed in the vessel body 111 and is used to stir the reactants inside the vessel body 111, thereby improving the reaction effect. A telescopic component 120 is disposed in the vessel body 111, that is, the mounting pipe 121 is installed at the top of the vessel body 111, and the bottom end of the connecting pipe 122 extends into the vessel body 111; a recovery component 150 is connected to the vessel body 111 to obtain and recover the cleaning liquid inside the vessel body 111.

[0044] In one embodiment, the distance D between the central axis of the telescopic component 120 and the central axis of the reactor 110 is: 1 / 2R ≤ D ≤ 2 / 3R, where R is the inner radius of the reactor. This ensures that the telescopic component 120 is radially spaced from the stirring structure 112 in the reactor 110, preventing collisions between the connecting pipe 122 and its spray ball 130 and the stirring structure 112 during movement.

[0045] In one embodiment, the reaction apparatus further includes a discharge valve 161 and a discharge pipe 162. The discharge valve 161 is connected to the bottom of the reaction vessel 110, and one end of the discharge pipe 162 is connected to the discharge valve 161 and the other end is connected to the recovery component 150, thereby conveying the cleaned material in the reaction vessel 110 to the recovery component 150, through which the cleaning liquid is recycled and reused.

[0046] In one embodiment, the recovery assembly 150 includes a recovery pump 151 and a separator 152. The reactor 110 is connected to the separator 152 via the recovery pump 151, so that the material in the reactor 110 is transported to the separator 152 via the recovery pump 151. The separator 152 is used to separate the solids and the cleaning fluid, and to transport the cleaning fluid to the liquid supply assembly 140. Specifically, the recovery pump 151 is connected to the discharge pipe 162, and the liquid phase outlet of the separator 152 is connected to the storage tank 141, thereby transporting the cleaning fluid to the storage tank 141 for reuse. Optionally, the separator 152 can be a centrifuge or a filter, as long as it can separate the solids and the cleaning fluid, and is not limited thereto.

[0047] In addition, it is understood that after the cleaning fluid cleans the reactor 110, the cleaned substances include the cleaning fluid as well as the solid substances such as precipitates and gels that have been washed off; the separator 152 is a solid-liquid separator that can separate the solid substances and the cleaning fluid, and transport the separated cleaning fluid to the storage tank 141.

[0048] Furthermore, the recycling assembly 150 also includes a solid phase collection tank 153, which is connected to the solid phase outlet of the separator 152 to collect the solid phase material separated in the separator 152. It can be determined that the collected solid phase material can be collected as a product, recycled and reused, or used for other purposes, without limitation.

[0049] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 The working process of the reaction apparatus in the above embodiments is described as follows:

[0050] After the reactor 110 has been operating for a period of time, the material input is paused. Simultaneously, the cleaning solution is pumped to the connecting pipe 122 via the transfer pump 142, and then sprayed out through the spray ball 130. During the spraying process, the connecting pipe 122 is rotated, causing the spray ball 130 to reciprocate up and down within the reactor 110, rotating during this process, thereby cleaning the inner wall of the reactor 110 and the stirring structure 112. During the cleaning process, the discharge valve 161 can remain open, and the cleaning material is pumped to the separator 152 via the recovery pump 151. The separator 152 separates the solid material from the cleaning solution, transferring the solid material to the solid collection tank 153 and the cleaning solution to the storage tank 141.

[0051] It should be noted that during the process of the spray ball 130 spraying the cleaning fluid, the stirring structure 112 can perform a stirring action to improve the cleaning effect. In addition, the rotation of the connecting pipe 122 can be done manually or by setting a drive structure, such as a motor directly driving the connecting pipe 122 to rotate back and forth.

[0052] In summary, the reaction apparatus provided in this application has at least the following advantages:

[0053] 1. The inside of the reaction vessel 110 is cleaned by spray ball 130 to avoid excessive deposition of precipitates and gels that may affect the reaction effect;

[0054] 2. The spray ball 130 can rise, fall and rotate during the spraying process, thereby spraying and cleaning the inside of the reaction vessel 110 in all directions and improving the cleaning effect;

[0055] 3. The cleaning solution can be recycled and reused by the cleaning component 150 after cleaning, reducing the consumption of cleaning solution and thus reducing cleaning costs.
