AI Technical Summary

Technical Problem

When using existing vertical water bath vaporizers, the heat exchange chamber is not filled with hot water, resulting in the heat exchange tubes not being fully submerged, which affects the heat exchange efficiency and makes it impossible to detect leaks inside the vaporizer in a timely manner.

Method used

Design a U-tube sheet cryogenic liquid vaporizer with liquid level monitoring function. Use a liquid level gauge to monitor the liquid level in the heat exchange chamber, vent the top gas through the vent pipe to ensure that the heat exchange chamber is filled with hot water, and monitor for leaks through the liquid level gauge and vent pipe to realize real-time adjustment of heat exchange efficiency and timely detection of leaks.

Benefits of technology

It improves heat exchange efficiency, ensures that hot water fills the heat exchange chamber, allows for timely detection and handling of leaks, avoids the formation of dead zones, and enhances the operational stability and efficiency of the equipment.

Abstract

The utility model discloses a kind of U-shaped tube plate low-temperature liquid gasifiers with liquid level monitoring function, it is related to gasifier technical field, and it includes: shell, heat exchange cavity is provided in shell;The top of heat exchange cavity is provided with liquid level meter, vent pipe is provided on the shell, one end of vent pipe extends to the top of heat exchange cavity, the other end extends to the outside of shell, vent pipe is provided with vent valve;The utility model inputs hot water in heat exchange cavity, the gas of the top of heat exchange cavity is exhausted through vent pipe, and it is convenient to fill in hot water;And because the top of heat exchange cavity is provided with liquid level meter, the liquid level of liquid in heat exchange cavity can be monitored, timely adjust the amount of hot water input, timely carry out hot water compensation, so as to maintain higher heat exchange efficiency;And when gas medium in heat exchange pipe leaks into heat exchange cavity, it will gather in the top of heat exchange cavity, by observing the liquid level abnormality of liquid level meter or monitoring the gas composition discharged by vent pipe, the condition of heat exchange pipe leakage can be known in time.
