Description

Technical Field

[0001] The utility model relates to the field of polyester production equipment, in particular to an energy-saving cleaning tank for polyester production. Background Art

[0002] Energy-saving cleaning tanks for polyester production are an indispensable part of the polyester manufacturing process. Their main function is to clean and recycle waste generated during the polyester production process, ensuring the stable operation of the production line and the control of product quality.

[0003] During normal production, a connecting device is usually installed at the bottom of the tank, which includes a filter and multiple valves, and is eventually connected to the esterification kettle. A nozzle is usually installed at the position close to the esterification kettle. Due to the accumulation of time, scale will appear on the wall of the 1214-T01 tank in the polyester device. When the liquid level is low, the scale will be exposed, which may cause the scale to fall off, causing the filter in the connecting device to suddenly become blocked, resulting in low pressure pump reporting, pump cavitation, and damage to the pump seal, forcing the pump to reduce production and grades. During emergency repairs on site, a large amount of raw materials will flow into the ditch, causing environmental pollution and employees may also be scalded.

[0004] Therefore, it is necessary to provide a new energy-saving cleaning tank for polyester production to solve the above-mentioned technical problems. Utility Model Content
