This invention discloses a monitoring method for a box-shaped keel on an ice-covered vessel, comprising the following steps: marking three spaced monitoring positions on the box-shaped keel, one of which is located at the heavy-load waterline at the bow; installing at least one monitoring component at each of the three monitoring positions; using a vibration sensor on the monitoring component to detect the vibration amplitude of the box-shaped keel and transmitting the detected vibration amplitude to a processor; and using a temperature sensor to detect the temperature of the box-shaped keel and transmitting the detected temperature to the processor; when the vibration amplitude detected by any vibration sensor exceeds a set amplitude, or when the temperature detected by any temperature sensor continuously rises to a set temperature within a set time period; reducing the vessel's speed from the current speed to a safe speed; and / or changing the vessel's course from the current course to a safe course. This method protects the scientific research equipment inside the box-shaped keel by monitoring its vibration amplitude and temperature changes.

The present disclosure relates to the technical field of chloroacetic acid tail gas treatment, and one embodiment of the present disclosure provides a processing device for monochloroacetic acid synthesis tail gas, which comprises a first acetic acid absorption tower, a second acetic acid absorption tower, a third acetic acid absorption tower and a gas inlet pipeline, and further comprises heat preservation covers, sun protection covers, fixing mechanisms, heat preservation and sun protection mechanisms and connecting mechanisms, two heat preservation covers are movably sleeved on the first acetic acid absorption tower, the second acetic acid absorption tower and the third acetic acid absorption tower, and the sun protection covers are installed on the outer sides of the heat preservation covers. Through the above technical solution, the technical problem that the tail gas inlet pipeline and the acetic acid recovery tower in the processing device for monochloroacetic acid synthesis tail gas lack effective heat preservation and sun protection structures in the prior art, so that the temperature inside the tail gas inlet pipeline and the acetic acid recovery tower is affected by the outside world and rises, the tail gas is greatly lost when the air temperature is high, and the tail gas is easily greatly lost, thereby affecting the recovery efficiency of acetic acid is solved.
