Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to an ester hydrolysis reactor. Background Technology

[0002] An ester hydrolysis reactor is a device specifically designed for the hydrolysis of ester compounds. Its working principle is primarily based on chemical reaction kinetics and thermodynamics. By controlling conditions such as reaction temperature, pressure, and material concentration, it promotes the hydrolysis of ester compounds with water, producing the corresponding acids and alcohols.

[0003] In the ester hydrolysis reaction, it is necessary to thoroughly mix the gas and liquid. However, in the prior art, the gas and liquid to be mixed are injected separately into the ester hydrolysis reactor. During the injection process, the liquid is injected into the reactor from the bottom, while the gas is transported into the reactor from the top. When transporting the gas, it is sprayed onto the liquid surface through a nozzle. During this process, the gas and liquid undergo a hydrolysis reaction to produce the corresponding acid and alcohol. However, due to its characteristics, some gas floats to the top of the ester hydrolysis reactor, resulting in the gas sprayed from the nozzle not being fully mixed with the liquid, leading to low mixing efficiency and affecting the hydrolysis effect of the gas and liquid. Utility Model Content

[0004] The present invention aims to provide an ester hydrolysis reactor that can fully mix gas and liquid, thereby improving mixing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 1) An ester hydrolysis reactor, comprising a tank, wherein the top of the tank is provided with an air inlet pipe extending downward into the tank body, the inlet of the air inlet pipe is provided with a nozzle, the end face of the nozzle away from the air inlet pipe is provided with an air outlet and a liquid outlet, the nozzle is provided with a gas channel and a liquid channel, the gas channel is connected to the air outlet, and the liquid channel is connected to the liquid outlet.

[0007] This invention features a gas channel and a liquid channel within the nozzle. Gas is injected into the tank through the gas channel and outlet, while liquid is injected into the tank through the liquid channel and outlet. During this process, gas and liquid can be simultaneously injected into the tank through the nozzle. Simultaneously, the gas and liquid mix immediately after exiting the nozzle, undergoing hydrolysis to produce the corresponding acids and alcohols. Furthermore, as the gas and liquid fall downwards, they mix further. Additionally, the liquid splashes as it reaches the bottom of the tank, mixing again with the surrounding gas. Therefore, the mixing efficiency is improved, resulting in a more complete hydrolysis reaction between the gas and liquid.

[0008] 2) An ester hydrolysis reactor according to 1), wherein:

[0009] The tank has a liquid inlet and a liquid outlet on both sides of the bottom. The liquid outlet is connected to the liquid channel through a flexible hose, and a suction pump is installed on the flexible hose.

[0010] In this invention, a liquid inlet is provided at the bottom of the tank to facilitate the injection of liquid into the tank. Gas is sprayed onto the liquid surface through a nozzle. During this process, the gas mixes with the liquid at the bottom of the tank, undergoing hydrolysis to generate the corresponding acids and alcohols. Simultaneously, a liquid outlet is provided at the bottom of the tank. A suction pump extracts the liquid from the bottom of the tank and delivers it through a hose to the liquid channel inside the nozzle. The liquid is then sprayed out simultaneously with the gas through the nozzle, allowing the liquid to circulate and mix with the gas repeatedly, thus improving mixing efficiency.

[0011] 3) An ester hydrolysis reactor according to 1), wherein:

[0012] Several fixed supports are evenly distributed along the height direction on the outer wall of the tank, and the hose passes through the fixed supports in sequence.

[0013] In this invention, several fixed supports are evenly distributed along the height direction on the outer side wall of the tank. The fixed supports can prevent the hose from moving, deforming or being damaged due to pressure, gravity or external force during the liquid transportation process.

[0014] 4) An ester hydrolysis reactor according to 1), wherein:

[0015] The gas channel is a straight channel, and the gas channel includes a front channel and a rear channel. The inner diameter of the rear channel is twice the inner diameter of the front channel.

[0016] In this invention, the inner diameter of the rear channel is twice that of the front channel. When gas passes through the front channel, the gas velocity increases, forming a high-speed gas flow. This high-speed gas flow can disperse the liquid into finer droplets, thereby increasing the contact area between the gas and liquid and improving the mixing efficiency. Simultaneously, the high-speed gas flow can increase the hydrolysis reaction rate, thus improving the efficiency of the gas-liquid hydrolysis reaction.

[0017] 5) An ester hydrolysis reactor according to 1), wherein:

[0018] The liquid channel includes an annular channel and an inclined channel. The annular channel is fitted onto the front end channel and is connected to the inclined channel.

[0019] In this invention, an annular channel is fitted onto the front channel, allowing the liquid to be evenly distributed around the gas when sprayed through the nozzle. This increases the contact area between the gas and liquid, enabling the gas to more effectively disperse the liquid into fine droplets, thereby improving mixing efficiency. Furthermore, the annular channel is connected to an inclined channel, facilitating the flow of liquid from the inclined channel into the annular channel.

[0020] 6) An ester hydrolysis reactor according to 5), wherein:

[0021] The inner diameter of the annular channel is the same as the inner diameter of the rear channel.

[0022] In this invention, the inner diameter of the annular channel is the same as the inner diameter of the rear channel, which allows the gas and liquid to be mixed in matching amounts when they are sprayed out of the nozzle at the same time, so that the gas and liquid can be mixed evenly and avoid low mixing efficiency caused by mismatch in liquid volume.

[0023] Compared with the prior art, this utility model also has the following technical effects:

[0024] This invention incorporates gas and liquid channels within the nozzle. Gas is injected into the tank through the gas channel and outlet, while liquid is injected into the tank through the liquid channel and outlet. During this process, gas and liquid can be simultaneously injected into the tank through the nozzle. Immediately after being ejected from the nozzle, the gas and liquid mix, undergoing hydrolysis to produce the corresponding acids and alcohols. Furthermore, as the ejected gas and liquid fall downwards, they further mix. Additionally, as the liquid reaches the bottom of the tank, it splashes, further mixing with the surrounding gas. Therefore, this design improves mixing efficiency, resulting in a more complete hydrolysis reaction between the gas and liquid. Attached Figure Description

[0025] Figure 1 This is a schematic diagram of an ester hydrolysis reactor according to the present invention.

[0026] Figure 2 This is a cross-sectional view of the nozzle in an ester hydrolysis reactor according to the present invention. Detailed Implementation

[0027] The following detailed description illustrates the specific implementation method:

[0028] The reference numerals in the accompanying drawings include: tank body 1, air inlet pipe 2, nozzle 3, air outlet 4, liquid outlet 5, gas channel 6, liquid channel 7, liquid inlet 8, liquid outlet 9, fixed bracket 10, front channel 11, rear channel 12, annular channel 13, and inclined channel 14.

[0029] See the example. Figure 1 and Figure 2 As shown, in this embodiment, an ester hydrolysis reactor includes a tank 1. The top of the tank 1 is provided with an air inlet pipe 2 extending downward into the tank 1. The inlet of the air inlet pipe 2 is provided with a nozzle 3. The end face of the nozzle 3 away from the air inlet pipe 2 is provided with an air outlet 4 and a liquid outlet 5. A gas channel 6 and a liquid channel 7 are opened inside the nozzle 3. The gas channel 6 is connected to the air outlet 4, and the liquid channel 7 is connected to the liquid outlet 5.

[0030] In this embodiment, a gas channel 6 and a liquid channel 7 are provided within the nozzle 3. Gas is injected into the tank 1 through the gas channel 6 and the gas outlet 4, while liquid is injected into the tank 1 through the liquid channel 7 and the liquid outlet 5. During this process, gas and liquid can be simultaneously injected into the tank 1 through the nozzle 3. Simultaneously, the gas and liquid mix immediately after being ejected from the nozzle 3, undergoing hydrolysis to generate the corresponding acids and alcohols. Furthermore, as the gas and liquid ejected from the nozzle 3 fall downwards, they further mix. Additionally, when the liquid falls to the bottom of the tank 1, it splashes, and the splashed liquid mixes again with the surrounding gas. Therefore, the mixing efficiency is improved, resulting in a more complete hydrolysis reaction between the gas and liquid.

[0031] Secondly, liquid inlet 8 and liquid outlet 9 are provided on both sides of the bottom of the tank 1. The liquid outlet 9 is connected to the liquid channel 7 through a hose, and a suction pump is provided on the hose.

[0032] In this embodiment, a liquid inlet 8 is provided at the bottom of the tank 1 to facilitate the injection of liquid into the interior of the tank 1. Gas is sprayed onto the liquid surface through a nozzle 3. During this process, the gas mixes with the liquid at the bottom of the tank 1, undergoing hydrolysis to generate the corresponding acids and alcohols. Simultaneously, a liquid outlet 9 is provided at the bottom of the tank 1. After the liquid at the bottom of the tank 1 is extracted by a suction pump, it is transported through a hose to the liquid channel 7 inside the nozzle 3. The liquid is sprayed out simultaneously with the gas through the nozzle 3, allowing the liquid to circulate and mix with the gas repeatedly, thereby improving the mixing efficiency.

[0033] See Figure 1 As shown, several fixed supports 10 are evenly distributed along the height direction on the outer side wall of the tank 1, and the hose passes through the fixed supports 10 in sequence.

[0034] In this embodiment, several fixed supports 10 are evenly distributed on the outer wall of the tank 1 along its height direction. The fixed supports 10 can prevent the hose from moving, deforming or being damaged due to pressure, gravity or external force during the liquid transportation process.

[0035] See Figure 2 As shown, the gas channel 6 is a straight channel, which includes a front channel 11 and a rear channel 12. The inner diameter of the rear channel 12 is twice the inner diameter of the front channel 11.

[0036] In this embodiment, the inner diameter of the rear channel 12 is twice the inner diameter of the front channel 11. When gas passes through the front channel 11, the gas velocity increases, forming a high-speed gas flow. This high-speed gas flow can disperse the liquid into finer droplets, thereby increasing the contact area between the gas and the liquid and improving the mixing efficiency. At the same time, the high-speed gas flow can increase the reaction rate, thereby improving the hydrolysis reaction efficiency between the gas and the liquid.

[0037] See Figure 2 As shown, the liquid channel 7 includes an annular channel 13 and an inclined channel 14. The annular channel 13 is fitted onto the front end channel 11, and the annular channel 13 is connected to the inclined channel 14.

[0038] In this embodiment, the annular channel 13 is fitted onto the front channel 11, allowing the liquid to be evenly distributed around the gas when sprayed through the nozzle 3. This increases the contact area between the gas and liquid, enabling the gas to more effectively disperse the liquid into fine droplets, thereby improving mixing efficiency. Furthermore, the annular channel 13 is connected to the inclined channel 14, facilitating the flow of liquid from the inclined channel 14 into the annular channel.

[0039] See Figure 2 As shown, the inner diameter of the annular channel 13 is the same as the inner diameter of the rear channel 12.

[0040] In this embodiment, the inner diameter of the annular channel 13 is the same as the inner diameter of the rear channel 12, which enables the gas and liquid to be mixed in matching amounts when they are sprayed out through the nozzle 3 at the same time, so that the gas and liquid can be mixed evenly and avoid low mixing efficiency caused by the mismatch between the amount of liquid and gas sprayed out through the nozzle 3.

[0041] In this embodiment, a gas channel 6 and a liquid channel 7 are provided within the nozzle 3. Gas is injected into the tank 1 through the gas outlet 4 via the gas channel 6, and liquid is injected into the tank 1 through the liquid outlet 5 via the liquid channel 7. During this process, gas and liquid can be simultaneously injected into the tank 1 through the nozzle 3. Simultaneously, the gas and liquid mix immediately after being ejected from the nozzle 3, undergoing hydrolysis to generate the corresponding acids and alcohols. Furthermore, as the gas and liquid ejected from the nozzle 1 fall downwards, they further mix. Additionally, when the liquid falls to the bottom of the tank 1, it splashes, and the splashed liquid mixes again with the surrounding gas. Therefore, the mixing efficiency is improved, resulting in a more complete hydrolysis reaction between the gas and liquid.

[0042] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
