Low temperature waste heat recovery and energy saving

Drying equipment

Under the entrustment of the National Development and Reform Commission, the expert assessment team of the Energy Saving Technology Center of Qinghai Province recently completed the energy saving and settlement of the sulfuric acid low-temperature waste heat recovery and utilization project, and determined that the energy conservation of the unit from January to August was 22,100 tons of standard coal. Significant.

It is understood that the Weidun 2×400,000-ton/year sulphuric acid plant low-level thermal energy utilization project, which is carried out by Handan Phosphate Fertilizer Plant, is a state financial fund subsidy energy-saving project during the “Eleventh Five-Year Plan” period. After the device is completed and put into operation, it can replace 320,000 tons of coal-fired steam annually, save 576,000 tons of circulating cooling water, save 1.92 million kilowatt-hours, and recover more than 30 million yuan from steam waste heat recovery. At the same time, the project also emits a certain amount of carbon dioxide, which has better environmental benefits.
