Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vaporizers, in particular to a cold-brittle-proof liquid level precise monitoring and control mechanism. Background Art
[0002] A water bath vaporizer is a device that vaporizes low-temperature liquid gas into gaseous gas by exchanging heat between hot water and low-temperature liquid gas.
[0003] However, at present, the water bath vaporizer controls the liquid level of the water bath vaporizer to ensure that the liquid level of the water bath vaporizer is at a high level, so as to increase the heat exchange area between hot water and low-temperature medium. Otherwise, when the low-temperature liquid enters the water bath vaporizer, it will cause incomplete vaporization of the low-temperature liquid or the temperature after vaporization will be too low. When the temperature is lower than -10℃, it will cause the water bath outlet pipeline to become cold and brittle. Utility Model Content

Through the small-diameter liquid discharge end, the heat transfer liquid fully fills the interior of the heat exchange tube, making the heat exchange uniform.
