[0026] Working principle: The differential pressure coupled distillation tower is a distillation tower design, which is usually used for the separation of multi-component mixtures. The tower body is the main structure of the differential pressure coupled distillation tower, which is usually a vertical cylindrical shape and is made of high-strength stainless steel. The tower plates inside the tower body are the key components for achieving separation. The heat exchanger is usually used in conjunction with the differential pressure coupled distillation tower to provide and absorb heat to regulate and control the temperature inside the tower body. A plurality of material guide pipes 4 are installed on one side of the distillation tower body 1. The plurality of material guide pipes 4 can mainly transport the original mixture and can transport the original mixture to the interior of the distillation tower body 1. A discharge mechanism is installed on the top of the distillation tower body 1 to guide the separated product to the outside world. After starting the circulation pump 3, the reflux pipe 2 can continue to guide the mixture at the bottom of the distillation tower body 1 to the top position of the distillation tower body 1. The mixture can be processed repeatedly, and several covering covers 10 can cover and wrap the outer surface of the distillation tower body 1. The two covering covers 10 at the top are connected to the moving rod body 8 by two extension rods 9. Therefore, under the movement of the moving rod body 8, several covering covers 10 will also move, thereby extending the service life of the differential pressure coupled distillation tower.
