Description

Technical Field

[0001] This utility model relates to the field of chemical separation technology, specifically a cryogenic heat exchange device for light and heavy components of diethyl carbonate. Background Technology

[0002] Diethyl carbonate, as a key organic chemical raw material, has a wide range of important applications in many fields such as pharmaceutical synthesis, pesticide preparation and electronic chemical production due to its unique chemical properties, and has a very broad market prospect.

[0003] Patent CN222086773U discloses a cryogenic heat exchange device for light and heavy components of methyl ethyl carbonate, including a base and a reaction vessel. A mixing tank for mixing materials is bolted to one side of the base. A pipe B connecting to the reaction vessel is inserted into the outside of the mixing tank. A pipe A connecting to a cooler is inserted into the outside of the reaction vessel. A fixing pipe connecting to the cryogenic heat exchanger is screwed to the outside of the cooler. A conveying pipe connecting to a material storage tank is screwed to the outside of the cryogenic heat exchanger. A fixing frame supporting the cryogenic heat exchanger is bolted to the outside of the base. A motor B that drives the threaded sleeve outside the one-way lead screw to rotate is bolted inside the fixing frame.

[0004] This cryogenic heat exchange device for light and heavy components of ethyl methyl carbonate, via a vertical rod, motor A, stirring rod, horizontal rod, and transmission plate, allows the material to be mixed in a mixing tank. Motor A drives the vertical rod to rotate, and the stirring rod outside the vertical rod agitates the catalyst inside the tank, ensuring thorough contact between the material and catalyst. Simultaneously, the horizontal rod drives the transmission plate to scrape the inner wall of the mixing tank, facilitating the removal of foreign matter adhering to the inner wall. While suitable for processing diethyl carbonate, this device has limitations. For example, it can only rotate the material and catalyst in one direction, failing to achieve multi-directional mixing, resulting in uneven mixing, small contact area, and low mixing efficiency, thus not meeting current requirements.
