Daqing Petrochemical Plastic Factory successfully applied its new cooling system
The Daqing Petrochemical Company Plastics Plant's high-pressure polyethylene finished product packaging and blow-molding cooling system renovation project lasted for half a year. The original product packaging line was put into use in 2005. Due to frequent occurrence of high-pressure gas interlock alarms and unplanned parking of ice machines in the cooling system, waste was generated. In order to solve this problem, this factory introduced condensation water instead of the original ice machine cooling method from the production device. The new investment cooling system operated smoothly and effectively reduced the waste loss caused by parking. It can save more than 2 million yuan annually for the enterprise. .
