Ion exchange resin tank for improving isopropanol preparation efficiency

Abstract

The invention discloses an ion exchange resin tank capable of improving isopropanol preparation efficiency, and relates to the field of isopropanol preparation devices, the ion exchange resin tank comprises a tank body, and ion exchange resin is arranged in the tank body; a liquid inlet pipe is fixedly arranged at the upper end of the tank body, and a liquid outlet pipe is fixedly arranged at the lower end; a liquid return outlet pipe is fixedly arranged at the lower end of the tank body, and a liquid return inlet pipe is fixedly arranged at the upper end; a liquid return pump for driving liquid in the liquid return outlet pipe to flow into the liquid return inlet pipe is connected between the liquid return outlet pipe and the liquid return inlet pipe; and the liquid return outlet pipe and the liquid return inlet pipe are communicated with the interior of the tank body. The liquid return pump inputs liquid at the lower end of the tank body to the upper end of the tank body through the liquid return inlet pipe, and the liquid at the upper end of the tank body flows downwards, so that the liquidity of the liquid in the tank body is improved, and an isopropanol raw material in the tank body is in full contact with ion exchange resin; therefore, the ion exchange efficiency between the isopropanol raw material and the ion exchange resin is improved, and the preparation efficiency of isopropanol is improved.

Description

technical field [0001] The present application relates to the field of isopropanol preparation devices, in particular to an ion exchange resin tank for improving isopropanol preparation efficiency. Background technique [0002] Isopropyl alcohol is a colorless, transparent liquid with a pungent odor. It can be used as a disinfectant and a cleaning agent, especially in the fields of surface cleaning and etching of circuit boards, chips, and silicon wafers. In the production and preparation process of isopropanol, it is necessary to use an ion resin tank for deionization treatment to reduce the content of metal impurities in isopropanol and improve the purity of isopropanol. [0003] An ion resin tank, refer to figure 1 , which includes a tank body 1, the tank body 1 is filled with ion exchange resin 2; the side wall of the upper end of the tank body 1 is welded and fixed with a liquid inlet pipe 11, and the lower end of the tank body 1 is welded and fixed with a liquid outle...

Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor thinks that ion exchange resins are generally granular solids, and the isopropanol raw material located in the gap between the ion exchange resins is difficult to contact with the ion exchange resins, thereby affecting the isopropanol raw material and ion exchange. The ion exchange efficiency between the resins leads to low production efficiency of isopropanol, so it needs to be improved
