Description

Technical Field

[0001] This utility model relates to the technical fields of equipment such as chemical engineering and bioengineering, and in particular to a multi-source synergistic high-efficiency gas blowing device for a reaction tank. Background Technology

[0002] In many fields such as chemical engineering and bioengineering, the efficiency of gas-liquid reactions in reaction tanks is crucial. Currently, most reaction tanks use relatively simple traditional gas injection methods, which often result in uneven gas distribution.

[0003] As shown in the attached diagram of the instruction manual. Figure 1 As shown, this is a reaction vessel in the prior art. Label 1 represents the reaction vessel, and label 2 represents the gas inlet pipe. Gas is blown in from only a single inlet, causing it to tend to accumulate locally at the bottom, preventing sufficient contact with the liquid. This results in low mass transfer efficiency, incomplete reaction, and negatively impacts product quality and production efficiency. Furthermore, existing devices lack synergistic design to promote gas-liquid mixing, making it difficult to meet the growing demand for high-efficiency reactions.

[0004] The patent application number "CN201920704304.4" discloses "a gas-liquid mixing device for preparing surfactants". Although it achieves simultaneous stirring and aeration, which increases the efficiency of gas dissolving into liquid to a certain extent, its dissolution efficiency is still not high enough. Utility Model Content

[0005] The purpose of this invention is to provide a multi-source synergistic high-efficiency gas induction device for a reaction tank, which improves gas-liquid mass transfer efficiency and achieves uniform gas distribution within the reaction tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-source synergistic high-efficiency gas induction reaction tank device includes a reaction tank, the inside of which is a liquid material for mixing gases. An annular pipe is sleeved on the outside of the reaction tank. One end of the annular pipe is an air inlet. A first air outlet pipe is provided on the annular pipe. The end of the first air outlet pipe is connected to the air inlet pipe extending into the reaction tank.

[0008] The lower part of the reaction tank is provided with a liquid outlet pipe, which is connected to the inlet of the jet pump. The outlet of the jet pump is connected to the first inlet of the jet injector through a liquid guide pipe. The outlet of the jet injector is connected to the liquid inlet pipe that extends into the reaction tank.

[0009] Preferably, the annular tube is further provided with a second air outlet pipe, the end of which is connected to the second inlet of the injector.

[0010] Preferably, the air inlet pipe is located at the bottom of the reaction tank.

[0011] Preferably, six first exhaust pipes are arranged in an array on the outside of the reaction tank, and the exhaust pipes correspond one-to-one with the first exhaust pipes.

[0012] Preferably, the reaction tank is equipped with a stirring device.

[0013] Preferably, the stirring device includes a power unit located outside the reaction tank and a stirring shaft extending into the reaction tank, wherein stirring blades are provided on the stirring shaft.

[0014] Preferably, the stirring blades are arranged in two places from top to bottom on the stirring shaft, and each stirring blade includes four blades.

[0015] Preferably, the bottom of the reaction tank is a slope that slopes from one end to the other, and the interface between the liquid outlet pipe and the reaction tank is located at the lowest end of the slope.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. High mass transfer efficiency: Through the cooperation of the ejector and the ejector pump, the gas and liquid are mixed twice in the ejector, which greatly increases the gas-liquid contact area, strengthens the mass transfer process, and significantly improves the reaction efficiency.

[0018] 2. Uniform gas distribution: Multiple bottom gas inlets and annular pipes work together to allow gas to enter the reaction tank from different positions at the bottom and top, overcoming the problem of uneven gas distribution caused by traditional single inlets and ensuring sufficient gas-liquid contact throughout the reaction tank.

[0019] 3. The stirring device can stir the liquid in the reaction tank, further promoting gas-liquid mixing. Attached Figure Description

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0024] The present invention will now be further described with reference to the accompanying drawings. Example

[0025] like Figure 2 and Figure 3 As shown, a multi-source synergistic high-efficiency gas-injection reaction tank device includes a reaction tank 1, inside which is a liquid mixture containing the gas to be mixed. An annular pipe 2 is fitted around the outside of the reaction tank 1. One end of the annular pipe 2 is an inlet 21, and a first outlet pipe 22 is provided on the annular pipe 2. The end of the first outlet pipe 22 is connected to an inlet pipe 24 extending into the reaction tank 1. In this embodiment, six first outlet pipes 22 are arranged in an array on the outside of the reaction tank 1. The inlet pipes 24 are located at the lower part of the reaction tank 1 and correspond one-to-one with the first outlet pipes 22. The gas enters the annular pipe 2 through the inlet 21, and then enters the reaction tank 1 through the first outlet pipe 22 and the inlet pipe 24, mixing with the liquid mixture therein.

[0026] A liquid outlet pipe 51 is provided at the lower part of the reaction tank 1. In this embodiment, the bottom of the reaction tank 1 is a slope sloping from left to right. The interface between the liquid outlet pipe 51 and the reaction tank 1 is located at the lowest end of the slope, facilitating the outflow of liquid. The liquid outlet pipe 51 is connected to the inlet of the jet pump 5. The outlet of the jet pump 5 is connected to the first inlet of the ejector 4 through the liquid guide pipe 52. The outlet of the ejector 4 is connected to the inlet pipe 41 extending into the reaction tank 1. The jet pump 5 can draw out the liquid from the reaction tank 1 through the liquid outlet pipe 51, and the liquid enters the ejector 4 along the liquid guide pipe 52. Then, the liquid flows back into the reaction tank 1 from the top along the inlet pipe 41, improving the gas-liquid mixing efficiency.

[0027] The annular pipe 2 is also provided with a second air outlet pipe 23. The end of the second air outlet pipe 23 is connected to the second inlet of the injector 4. With this arrangement, the gas and liquid can be mixed twice in the injector 4, which further improves the mixing efficiency of the gas and liquid.

[0028] A stirring device 3 is installed inside the reaction tank 1. The stirring device 3 includes a power unit located outside the reaction tank 1 and a stirring shaft 31 extending into the reaction tank 1. Stirring blades 32 are installed on the stirring shaft 31. The stirring blades 32 are arranged in two places from top to bottom on the stirring shaft 31, each stirring blade including four blades, which are fixedly installed on the stirring shaft 31 by a hub and are evenly distributed. Stirring further improves the gas-liquid mixing efficiency.

[0029] When this device is in use, gas flows out from the gas source pipe, enters the annular pipe 2 through the air inlet 21, and flows in the annular pipe 2. After flowing in the annular pipe 2, part of the gas enters the bottom of the reaction tank 1 along the first air outlet pipe 22 and the air inlet pipe 24, where it is mixed with the liquid material. The other part of the gas flows out from the second air outlet pipe 23 to the ejector 4. At the same time, the ejector pump 5 draws out the liquid material in the reaction tank 1 and delivers it to the ejector 4. In the ejector 4, the gas and liquid material are mixed a second time, and the gas-liquid mixture flows out from the outlet of the ejector 4 and re-enters the reaction tank 1.

[0030] This multi-source air intake method and liquid circulation mixing mechanism allow gas to enter the reaction tank 1 from multiple angles and different positions, and to fully contact the liquid.
