Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, and particularly relates to a reaction kettle with a hydrogen-passing function. Background Art

[0002] The structure of a reaction kettle mainly consists of a kettle body, a transmission device, a stirring device, a heating device, a cooling device and a sealing device. It is a container capable of carrying out physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling and mixing at low and high speeds required by the process are realized. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine and food, and are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization and condensation.

[0003] When the existing reaction kettle transports hydrogen for hydrogenation reaction, due to the large diameter of the pipeline, the transported hydrogen forms large bubbles and emerges from the material immediately. However, the material in the kettle does not reach half of the reaction kettle. When hydrogen is passed, the hydrogen is at the top of the reaction kettle, resulting in less contact between the material and hydrogen, incomplete hydrogenation or more waste of hydrogen, causing the material to fail to meet the standards. During the hydrogen transportation process, the introduced hydrogen cannot emerge in the form of small-diameter bubbles and contact the material; when the reaction kettle passes hydrogen, there is a problem that the introduced hydrogen is not dispersed and does not contact the material in the form of tiny bubbles. Therefore, this application proposes a reaction kettle with a hydrogen-passing function. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reaction kettle with a hydrogen-passing function to solve the problem that there is no design on the reaction kettle to disperse the introduced hydrogen and make it contact the material in the form of tiny bubbles as mentioned in the above background art.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment

[0024] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a reactor with a hydrogen inlet function, including a reactor body 1. The reactor body 1 serves as a container for chemical reactions and is a conventional reaction container device, which will not be elaborated in detail in this application. Limit blocks 11 are provided on the inner side walls opposite to the reactor body 1. The limit blocks 11 are combined with the reactor body 1 by conventional methods, and the limit blocks 11 limit the connecting pipe 31; a gas transmission assembly, including a hydrogen inlet pipe 2 penetrating the surface of the reactor body 1 at one end, a connecting pipe 31 connected to the limit block 11 at one end, and a shunt pipe 3 installed between the symmetrically distributed connecting pipes 31. One end of the hydrogen inlet pipe 2 is connected to the opposite connecting pipe 31. When hydrogen is introduced, hydrogen enters the connecting pipe 31 from the hydrogen inlet pipe 2, then flows into the interior of the shunt pipe 3, and finally is shunted into the interior of the gas storage pipe 4; gas storage pipes 4 evenly distributed on the bottom surface of the shunt pipe 3. Guide plates 5 are provided symmetrically on the surface of the gas storage pipe 4. A water film screen 51 is provided on the inner surface of the guide plate 5. An air outlet 52 is provided on the surface of the guide plate 5. A waterproof and breathable membrane 53 is attached to the inner surface of the guide plate 5. The gas in the gas storage pipe 4 enters the interior of the guide plate 5 and emerges after passing through the waterproof and breathable membrane 53, the air outlet 52, and the water film screen 51. Hydrogen emerges from the micropores. The introduced hydrogen is dispersed and in the form of tiny bubbles to fully contact the material. The waterproof and breathable membrane 53 is made of a polymer waterproof and breathable material and has a microporous structure, which can achieve the effect of dispersing hydrogen. The water film screen 51 is made of corrosion-resistant stainless steel material. The water film screen 51 has a high surface tension on its surface, which can form a layer of material water film on the surface of the water film screen 51. The hydrogen dispersed through the micropores contacts the water film, enabling more contact between hydrogen and the material water film and avoiding waste of hydrogen or incomplete reaction.

[0025] In this embodiment, the hydrogen supply pipe 2 has an "L" shape. The hydrogen supply pipe 2, the connecting pipe 31, the shunt pipe 3, and the gas storage pipe 4 are internally connected. One end surface of the gas storage pipe 4 is provided with a connecting pipe 41 inserted into the shunt pipe 3. The gas storage pipe 4 and the guide plate 5 are bent. The interior of the gas storage pipe 4 is provided with a gas storage chamber 42. The hollow connecting pipe 41 communicates with the gas storage chamber 42. When hydrogen is supplied, hydrogen enters the connecting pipe 31 from the hydrogen supply pipe 2, then flows into the interior of the shunt pipe 3, and finally is shunted into the interior of the gas storage pipe 4. The interior of the guide plate 5 is provided with a gas chamber a. The surface of the gas storage pipe 4 is provided with a connecting hole. The gas storage chamber 42 communicates with the gas chamber a through the connecting hole. The hydrogen inside the gas storage pipe 4 enters the interior of the guide plate 5.

[0026] In this embodiment, the air outlet 52 has a tapered hole shape that is wide at one end and narrow at the other end, which is conducive to the flow of hydrogen. The wide-diameter end of the air outlet 52 is attached to the waterproof and breathable membrane 53, and the narrow-diameter end of the air outlet 52 contacts the water film gauze 51. The water film gauze 51 has a bent shape, and the outer surface of the water film gauze 51 fits the inner surface of the guide plate 5. A layer of material water film is formed on the surface of the water film gauze 51 by the material solution. The hydrogen dispersed through the micropores contacts the water film, so that the hydrogen contacts the material water film more, avoiding waste of hydrogen or incomplete reaction.

[0027] In this embodiment, a pressure strip 6 is provided on the surface of the gas storage pipe 4. The pressure strip 6 includes a middle fixing part installed on the surface of the gas storage pipe 4 and limiting parts symmetrically distributed at both ends. The limiting parts are bent. The inner surface of the water film gauze 51 fits the bending curve of the limiting parts. The pressure strip 6 serves to limit the water film gauze 51.

[0028] The working principle and usage process of the present utility model:

[0029] When hydrogen is supplied, hydrogen enters the connecting pipe 31 from the hydrogen supply pipe 2, and then flows into the interior of the shunt pipe 3;

[0030] The hydrogen inside the shunt pipe 3 is shunted into the interior of the gas storage pipe 4;

[0031] The gas in the gas storage pipe 4 enters the interior of the guide plate 5, and then emerges after passing through the waterproof and breathable membrane 53, the air outlet 52, and the water film gauze 51. Hydrogen emerges from the micropores. The supplied hydrogen is dispersed and in the form of tiny bubbles to fully contact the material. The waterproof and breathable membrane 53 is made of a polymer waterproof and breathable material and has a microporous structure, which can achieve the effect of dispersing hydrogen;

[0032] The water film gauze 51 is made of corrosion-resistant stainless steel material. The surface of the water film gauze 51 has a high surface tension, which can make the material solution form a layer of material water film on the surface of the water film gauze 51. The hydrogen dispersed through the micropores contacts the water film, so that the hydrogen contacts the material water film more, avoiding waste of hydrogen or incomplete reaction.

[0033] In summary: There is a design on the reactor to disperse the introduced hydrogen and make it in the form of tiny bubbles to fully contact with the material. The gas in the gas storage pipeline 4 enters the inside of the guide plate 5, passes through the waterproof and breathable membrane 53, the air outlet 52 and the water film screen 51 and then emerges. The hydrogen emerges from the micropores, and the introduced hydrogen is dispersed and in the form of tiny bubbles to fully contact with the material.
