Compression system and method for recovery plant

The embodiment of the invention provides a compression system and method for recycling equipment. The system comprises a compression module, a limiting detection module, an ultrasonic detection module, a current detection module and a Hall sensor detection module. Wherein the compression module is used for starting compression under the condition that the ultrasonic detection module detects that the height of the compressed object is greater than a first threshold value; when the compression force applied to the compressed object by the compression module reaches a second threshold value or the limit detection module detects that the compression module reaches a preset position, the compression work is stopped, and the compression module is withdrawn; the compression force is determined based on the motor current and the motor speed. According to the system, the compression capacity and the compression efficiency are effectively improved, the failure rate of compression equipment is reduced, and the safety of
