Abstract

The invention discloses a polyester waste heat utilization device. The invention aims to provide a polyester waste heat utilization device capable of comprehensively utilizing heat. The polyester waste heat utilization device comprises a reflux water storage tank, a reflux water delivery pump, an air cooler, a technological tower, a filament air conditioning unit, a hot water type lithium bromide refrigerator, a heat exchanger I, a heat exchanger II, a heat exchanger III, a heat exchanger IV, a pneumatic valve, a water inlet manifold and a return water manifold. The polyester waste heat utilization device has the characteristics of being simple in structure, high in waste heat utilization rate and the like.

Description

technical field [0001] The invention relates to the field of polyester chemical production, in particular to a polyester waste heat utilization device. Background technique [0002] As an important branch of the chemical industry, polyester production is also a high-energy-consuming industry. At present, with the economic development of our country, the pressure on the environment and energy is increasing. According to statistics, in 2012, 58.7% of my country's crude oil needs to be imported, and coal and natural gas The dependence on imports is also increasing, and the energy crisis is becoming more and more obvious. In the face of this situation, the work of energy conservation and consumption reduction is a long way to go. The national energy strategy also requires the continuous reduction of energy consumption per unit of GDP. Implement various energy-saving and consumption-reducing measures to reduce the energy consumption index per unit of product. [0003] The function...
