Description

Technical Field

[0001] This utility model specifically relates to the field of reaction vessel technology, and more specifically to an easy-to-clean sulfonation reaction vessel. Background Technology

[0002] A sulfonation reactor is a pressure vessel used for sulfonation reactions. The external main structure of the reactor is typically made of metal, serving to support and protect the internal components. The choice of material is crucial; highly corrosion-resistant materials such as stainless steel are generally selected because corrosive substances may be generated during the sulfonation reaction. The stirring device is one of the key components of the sulfonation reactor, used to agitate the reactants, ensuring thorough mixing, accelerating the reaction rate, and improving reaction efficiency. The stirring device typically consists of a motor, reducer, stirring shaft, and impeller.

[0003] Chinese Patent Publication No. CN 204234088U discloses a 2-naphthol sulfonation reactor, including a reactor cover with an equipment flange and a reactor body. The reactor body is provided with a jacket on the outside. The reactor body is provided with a high-speed stirring shaft and a low-speed stirring shaft. The high-speed stirring shaft is provided with a number of stirring blades from top to bottom. The lower end of the low-speed stirring shaft is connected to a scraper mechanism. The scraper mechanism includes a reactor wall scraper and a bottom scraper. The inner side of the reactor wall scraper is provided with the same number of stirring teeth as the stirring blades. The stirring blades and stirring teeth are arranged alternately, and the stirring blades extend into the gaps between two adjacent layers of stirring teeth.

[0004] The aforementioned patent uses a scraper to clean the inner wall during sulfonation. However, relying solely on the scraper to clean the vessel body will leave a significant amount of chemical residue on the corrosion-resistant layer of the inner wall, which can easily accelerate the corrosion rate of the corrosion-resistant layer on the inner wall. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-clean sulfonation reactor with a rotating spray cleaning mechanism. After sulfonation is completed, the inner wall of the reactor can be sprayed and cleaned with high-pressure water or cleaning agent to reduce the residue of chemical materials and avoid corrosion of the reactor; thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-clean sulfonation reactor includes a frame body on which multiple reactors are mounted, and a material feeder is installed on one side of each reactor. Each reactor includes a vessel body, a tank top cover is fixedly mounted on the top of the vessel body, and a drive device is mounted on the top of the tank top cover. An agitator is installed below the drive device. A cleaning component is installed on the outside of the agitator.

[0008] The cleaning assembly includes two spray components that are snapped and fixed to the stirring paddle. The two spray components are connected by a connecting pipe, and a vertical pipe is welded to the bottom of the connecting pipe.

[0009] As a further technical solution of this utility model, straight pipes are also vertically welded to the lower ends of the connecting pipe.

[0010] As a further technical solution of this utility model, the two spray elements are arranged symmetrically, and there are multiple nozzles in a rectangular array on the outer side of the spray elements.

[0011] As a further technical solution of this utility model, the lower end of the vertical pipe extends to the bottom outer side of the vessel body and is connected to a conveying pipe through a rotary joint; the vertical pipe and the vessel body are connected by a rotary seal.

[0012] As a further technical solution of this utility model, the top of the tank cover is provided with a manhole, and multiple fixing seats that are fixed to the frame body are evenly distributed on the outside of the vessel body; the bottom of the vessel body is also fixed with a drain port, which is located on one side of the conveying pipe.

[0013] As a further technical solution of this utility model, the vessel body includes an outer tank and an inner tank; the outer tank and the inner tank are integrally formed, and a cavity is reserved between the outer tank and the inner tank, and a heating wire is provided in the cavity; the heating wire is coiled around the outside of the inner tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, when sulfonating materials, the materials are added to the reaction vessel by a material additive, and then the driving device drives the stirring paddle to stir. The heating wire heats the inner tank, thereby ensuring the temperature of the chemical liquid during the reaction.

[0016] 2. In this utility model, when stirring chemical raw materials, compressed gas can be introduced from the conveying pipe. When the compressed gas enters the connecting pipe, a negative pressure will be generated at the straight pipe connection, which will cause the chemical liquid in the reactor to enter the connecting pipe. Under the push of the wind, the chemical liquid will be sprayed out from the spraying element through the nozzle. This can uniformly refine the chemical liquid and make the chemical liquid mix more thoroughly.

[0017] 3. In this invention, after the material reaction is complete, the material can be discharged through the drain port at the bottom; then, the cleaning liquid is introduced into the conveying pipe, and the cleaning liquid is transported to the connecting pipe and two spray components by external high-pressure equipment. The high-pressure cleaning liquid is sprayed onto the inner wall of the reactor through the nozzles to flush away the residual chemical materials on the inner wall of the reactor, thereby reducing the adhesion of chemical materials, reducing corrosion of the reactor, and improving its service life.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figure 1-9 In this embodiment of the present invention, an easy-to-clean sulfonation reactor includes a frame body 1, on which a plurality of reactors 3 are mounted, and a material feeder 2 is installed on one side of each reactor 3; the reactor 3 includes a vessel body 35, on which a tank top cover 31 is fixedly mounted, and a driving device 32 is mounted on the top of the tank top cover 31; a stirring paddle 36 is installed below the driving device 32; and a cleaning component 37 is installed on the outside of the stirring paddle 36.

[0034] The cleaning component 37 includes two spray elements 371 that are snapped and fixed to the stirring paddle 36. The two spray elements 371 are connected by a connecting pipe 372, and a vertical pipe 375 is welded vertically below the connecting pipe 372.

[0035] More specifically, the top of the tank cover 31 is provided with a manhole 33, and multiple fixing seats 34 fixed to the frame body 1 are evenly distributed on the outside of the vessel body 35; the bottom of the vessel body 35 is also fixed with a drain port 38, which is located on one side of the conveying pipe 377.

[0036] By adopting the above technical solution, when the material is sulfonated, the material is added to the reaction vessel 3 by the material additive 2, and then the driving device 32 drives the stirring paddle 36 to stir, so that the material can react at a certain temperature.

[0037] After the material reaction is complete, the material can be discharged through the drain port 38 at the bottom; then the cleaning liquid is introduced into the conveying pipe 377, and the cleaning liquid is transported to the connecting pipe 372 and the two spray components 371 by the external high pressure equipment. The high pressure cleaning liquid is sprayed onto the inner wall of the reactor 3 through the nozzle 374 to flush the residual chemical materials on the inner wall of the reactor 3, thereby reducing the adhesion of chemical materials and thus reducing the corrosion of the reactor 3.

[0038] Example 2

[0039] Please see the appendix Figure 6-9 In this embodiment, straight pipes 373 are also vertically welded below both ends of the connecting pipe 372.

[0040] By adopting the above technical solution, when stirring the chemical raw materials, compressed gas can also be introduced from the conveying pipe 377. When the compressed gas enters the connecting pipe 372, a negative pressure will be generated at the connection of the straight pipe 373, so that the chemical liquid in the reaction vessel 3 enters the connecting pipe 372. Under the push of the wind, the chemical liquid is sprayed out from the spraying element 371 through the nozzle 374. This can uniformly refine the chemical liquid and make the chemical liquid mix more thoroughly.

[0041] In this embodiment, the two spray elements 371 are arranged symmetrically, and there are multiple nozzles 374 in a rectangular array on the outer side of the spray elements 371.

[0042] In this embodiment, the lower end of the vertical pipe 375 extends to the bottom outer side of the vessel body 35 and is connected to the conveying pipe 377 through the rotary joint 376; the vertical pipe 375 and the vessel body 35 are connected by a rotary seal.

[0043] By adopting the above technical solution, since the two spray components 371 are fixedly connected to the stirring paddle 36, the two spray components 371 rotate along with the stirring paddle 36 when it rotates. By setting the rotary joint 376, it is possible to ensure the normal delivery of gas or cleaning liquid and the normal rotation of the spray components 371.

[0044] In this embodiment, the vessel body 35 includes an outer tank 351 and an inner tank 353; the outer tank 351 and the inner tank 353 are integrally formed, and a cavity is reserved between the outer tank 351 and the inner tank 353, in which a heating wire 352 is provided; the heating wire 352 is coiled around the outside of the inner tank 353.

[0045] By adopting the above technical solution, the heating wire 352 heats the inner tank 353, thereby ensuring the temperature of the chemical liquid during the reaction.

[0046] The working principle of this utility model is as follows: when the material is sulfonated, the material is added to the reaction vessel 3 through the material additive 2, and then the driving device 32 drives the stirring paddle 36 to stir. The heating wire 352 heats the inner tank 353, thereby ensuring the temperature of the chemical liquid when it reacts.

[0047] When stirring the chemical raw materials, compressed gas can be introduced through the conveying pipe 377. When the compressed gas enters the connecting pipe 372, a negative pressure will be generated at the connection of the straight pipe 373, so that the chemical liquid in the reactor 3 enters the connecting pipe 372. Under the push of the wind, the chemical liquid is sprayed out from the spraying element 371 through the nozzle 374. This can evenly refine the chemical liquid and make the chemical liquid mix more thoroughly.

[0048] After the material reaction is complete, the material can be discharged through the drain port 38 at the bottom; then the cleaning liquid is introduced into the conveying pipe 377, and the cleaning liquid is transported to the connecting pipe 372 and the two spray components 371 by the external high pressure equipment. The high pressure cleaning liquid is sprayed onto the inner wall of the reactor 3 through the nozzle 374 to flush the residual chemical materials on the inner wall of the reactor 3, thereby reducing the adhesion of chemical materials and thus reducing the corrosion of the reactor 3.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
