Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for hydrogen chloride organic solution, in particular to a device for uniformly mixing hydrogen chloride organic solution. Background Art

[0002] Hydrogen chloride organic solution has a wide range of applications in the pharmaceutical intermediates industry and is a raw material for the preparation of a variety of pharmaceutical intermediates. Various hydrogen chloride organic solutions are obtained by dissolving hydrogen chloride gas in methanol, ethanol, ethyl acetate, and other liquid organic substances. Currently, there are two main methods for producing hydrogen chloride organic solutions. The first is the direct-through method, which involves passing hydrogen chloride gas into a container containing liquid organic matter and dissolving the hydrogen chloride gas in the liquid organic matter through stirring or gas bubbling, thereby obtaining a hydrogen chloride organic solution. The second is the falling film absorption method, which uses multiple falling film absorbers in series to achieve reverse absorption of the liquid organic matter and hydrogen chloride gas, thereby obtaining a hydrogen chloride organic solution. Regardless of which method is used, the hydrogen chloride organic solution inevitably suffers from large fluctuations in hydrogen chloride concentration and poor uniformity, which affects subsequent use. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a device for uniformly mixing hydrogen chloride organic solution.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0005] A device for uniformly mixing hydrogen chloride and organic solution, comprising:

[0006] case;

[0007] The first hydrogen chloride organic solution inlet pipe and the second hydrogen chloride organic solution inlet pipe are respectively arranged on the upper part of the side walls at both ends of the shell;

[0009] A first built-in baffle and a second built-in baffle are vertically arranged in parallel with each other in the housing;

[0010] an agitator disposed in the housing and located between the first built-in baffle and the second built-in baffle;

[0011] The hydrogen chloride organic solution overflow outlet is provided on the side wall of the shell and is located between the first built-in baffle and the second built-in baffle;

[0012] Wherein, the first hydrogen chloride organic solution inlet pipe, the second hydrogen chloride organic solution inlet pipe, the nitrogen inlet pipe and the nitrogen outlet are all provided with switch valves.

[0013] The first hydrogen chloride organic solution inlet pipe, the second hydrogen chloride organic solution inlet pipe and the nitrogen inlet pipe are all installed on the shell through fastening flanges.

[0014] A plurality of openings are provided on the tops of the first built-in baffle and the second built-in baffle.

[0015] The nitrogen inlet pipe and the nitrogen outlet are respectively arranged at both ends of the shell, so that nitrogen can enter the shell from one end and flow out from the other end, completing the gas replacement in the shell.

[0016] The beneficial effects of the present invention are as follows: the present invention adds the present device to the existing conveying pipeline for hydrogen chloride organic solution products from the straight-through method or falling film absorption method to the packaging process, allowing the hydrogen chloride organic solution to enter the interior of the device simultaneously through the inlets at both ends of the device. Then, under the action of the first built-in baffle and the second built-in baffle, hydrogen chloride organic solutions of different concentrations are preliminarily mixed between the first built-in baffle and the second built-in baffle. At the same time, under the action of the agitator, the mixing effect is further improved. As the liquid level continues to rise, the evenly mixed hydrogen chloride organic solution naturally flows out through the hydrogen chloride organic solution overflow outlet to the packaging process. After adopting the present invention, the problem of large fluctuation range of hydrogen chloride concentration in the hydrogen chloride organic solution is solved, and the uniformity of the concentration of the hydrogen chloride organic solution is improved.
