Embodiment 1

[0024] The structure of the mixer

[0025] figure 1 The general structure of the loop mixer of the present invention is schematically shown.

[0026] Above and below are defined in the description of the invention with the orientation of the annular mixer in the drawings. The circulating mixer includes a tank body 1, a first opening 2 at the lower part of the tank body 1 and a second opening 3 at the upper part, and a guide cylinder 4 suspended and fixed in the tank body 1, wherein the guide cylinder 4 is free from the upper and lower parts. Cylindrical structure of the lid. The interior of the tank body 1 also includes a gas distributor 6 fixed under the guide tube 4. For example, the gas distributor 6 can be fixed inside the tank body 1 through a bracket 8; The first delivery pipe 10 of the nozzle 5 leads from the lower end of the tank body 1 to the interior of the tank body 1 , that is to say, the first delivery pipe 10 can pass through the first opening 2 and its two en...

Embodiment 2

[0033] Utilize the mixer of the present invention to prepare acetic acid, the schematic flow diagram is shown in Figure 5. The material flow rate of 2316g / h of methanol and 2311g / h of CO is continuously fed into the 5L zirconium material tank 1, and will contain 200wtppm of Rh, 1500wtppm of Ir, 1500wtppm of Ru, 9wt% Methyl iodide, the water of 5.5 % by weight, the methyl acetate of 12 % by weight, all the other are the reaction solution of 528g of acetic acid (the volume of the reaction solution is 4L) and pass into the tank 1 and carry out carbonylation reaction, and the temperature of reaction is 195 ℃ °C, and the reaction pressure was 2.8 MPa. The mixture obtained after the reaction is sent to a flash tower through a pipeline connected to the first opening 2 for flash distillation, and a gas phase component containing acetic acid and an acetic acid solution containing Rh, Ir and Ru are obtained in the flash tower. The acetic acid solution containing Rh, Ir and Ru in the ...

Abstract

The invention especially relates to a circulation mixer, belonging to the technical field of mixers. The circulation mixer comprises a tank with at least one opening, a guide shell fixed in the tank in a suspension manner, a nozzle located below the guide shell, and a gas distributor fixedly arranged in the tank and located below the guide shell, wherein the nozzle is connected with a first conveyer pipe which penetrates the sidewall of the tank and extends to the interior of the tank, and the gas distributor is connected with a second conveyer pipe which penetrates the sidewall of the tank and extends to the interior of the tank. The circulation mixer is simple in structure; during mixing of equal amounts of raw materials, the circulation mixer achieves the purpose of liquid-liquid or gas-liquid mixed mass transfer or heat transfer through formation of circulation in the circulation mixer; the size of the mixer may be substantially reduced compared with mixers in the prior art; and in particular, when the mixer is used as a chemical reactor needing heating, and heat and mass transfer efficiency of the reactor is high.

Description

technical field [0001] The invention relates to the technical field of mixers, in particular to a circulating mixer. Background technique [0002] In the process of chemical synthesis or composition preparation, the reactor used for chemical synthesis or the mixer used for composition preparation is generally a conventional mechanically stirred vessel, which can effectively carry out liquid-liquid and gas-liquid mixing However, the shaft seal and bearing required for the mechanical transmission using mechanical stirring are easily damaged in long-term operation, resulting in shutdown and maintenance, and it is difficult to achieve continuous, stable and safe operation, which is the deficiency of the existing technology. [0003] When the mixed raw materials or the prepared reactive species contain corrosive gases and / or liquids, the corrosive substances will increase the corrosion of equipment, thereby damaging the container, causing shutdowns and safety accidents. In some ...
