Description

Gas-liquid nano reactor Technical Field The utility model relates to the field of gas-liquid mixing, in particular to a gas-liquid nano-reactor. Background It is well known that gas-liquid mass transfer is a very common technical means in the fields of chemical production and the like. The purpose of gas-liquid mass transfer is to absorb or desorb a gas in a liquid. From the aspect of mass transfer, the most direct way to increase the rate of gas-liquid reaction is to increase the total contact area of gas and liquid, such as the gas-liquid mixing reactor disclosed in the patent publication CN217410737U, where liquid and gas are mixed by micro-channels to react. However, some gas-liquid reactions are slow, such as waste water oxidation to remove COD (which can describe what gas phase and liquid phase reactions are slow), and only the existing gas-liquid mixing reactor is adopted, so that the gas-liquid reaction is still low in efficiency and insufficient in reaction, and therefore, the gas-liquid contact area needs to be further extracted. Disclosure of utility model The utility model provides a gas-liquid nano-reactor, which solves the problem of low reaction efficiency of substances with slower gas-liquid reaction, and utilizes a mixing cavity to generate a cavitation effect so as to enable gas and liquid to reach the nano-level, thereby improving the gas-liquid contact area and increasing the reaction efficiency. The utility model is realized by the following technical scheme: The gas-liquid nano reactor comprises a columnar reactor body, wherein a plurality of mixing cavities which are communicated in sequence are arranged on the reactor body along the axis direction; The mixing cavity is sequentially divided into a converging section and a diffusing section along the fluid flow direction, the converging section is a first conical cavity with gradually reduced inner diameter along the fluid flow direction, and a plurality of diversion trenches converging towards the center to form a vortex shape are arranged on the inner wall of the converging section; The diffuser section is a second conical cavity with gradually enlarged inner diameter along the fluid flow direction, and the second conical cavity is communicated with the first conical cavity. Further, adjacent mixing cavities are communicated through a transition cavity, and the inner wall of the transition cavity is a cylindrical surface. Further, a front end cover is arranged at the front end of the reactor body, and the front end cover is communicated with an air inlet pipe and a liquid inlet pipe; The rear end of the reactor body is provided with a rear end cover, and the rear end cover is provided with a mixed fluid outlet pipe. Further, the number of the diversion trenches is 5-7. Further, the number of the mixing cavities is 5-9. Further, the reactor body is made of 316l stainless steel, alloy silicon carbide, special ceramics or special tetrafluoro materials. Compared with the prior art, the utility model has the following beneficial effects: 1. The gas-liquid nano reactor comprises a reactor body, wherein a plurality of mixing cavities which are sequentially communicated are arranged in the axial direction of the reactor body, and the mixing cavities are sequentially divided into a collecting section and a diffusing section along the fluid flow direction; When the gas and the liquid flow through each mixing cavity in sequence, the gas and the liquid in the fluid are enabled to generate cavitation effect by utilizing the ultrahigh flow rate of the fluid, so that the gas and the liquid reach the nanometer level and are invisible to naked eyes, and a huge contact area is formed between the gas and the liquid to increase the reaction efficiency between the gas and the liquid; 2. the inner wall of the collecting section is provided with a plurality of diversion trenches converging towards the center to form vortex shapes, so that a part of fluid can be diverted to generate rotational flow, and other fluids reach the nano-scale at the junction of the collecting section and the diffusing section due to cavitation effect, thereby improving the gas-liquid contact area and increasing the reaction efficiency; 3. The number of the mixing cavities is 5-9, and the mixing cavities are distributed along the axial direction of the reactor body, so that gas and liquid can be mixed for multiple times, the contact time is greatly prolonged, and the reaction efficiency is improved.
