AI Technical Summary
Technical Problem
The energy carried by the waste gas generated during the vegetable oil refining process is not fully utilized, resulting in waste of resources.
Method used
A waste gas recovery and utilization device is designed to exchange heat between waste gas and dewaxed oil and non-deodorized oil through a heat exchanger and a vacuum unit. The heat of the recovered waste gas is used to preheat the dewaxed oil and non-deodorized oil, and the waste gas is converted into electrical energy or thermal energy.
Benefits of technology
Effectively utilize waste gas heat, save energy, reduce production costs, improve production efficiency, and achieve efficient utilization of waste gas resources.
