A metal smelting enterprise in Zhejiang Province has invested in the construction of a modern multi metal staircase utilization factory. The factory's production line has an annual capacity to dispose of 15000 tons of catalysts and 200000 tons of waste metal sludge. It adopts oxygen enriched side blowing smelting technology and has achieved significant benefits since its commissioning in 2020. It has attracted many peer enterprises to visit and exchange ideas at the factory, and has received widespread attention from the industry, with good demonstration significance.
In the early stage of project preparation, the factory conducted a detailed comparison of oxygen consumption processes in the oxygen enriched side blowing furnace, and ultimately decided to adopt the widely used pressure swing adsorption oxygen production technology and scheme in China. In the third quarter of 2020, after intense and orderly construction, the production process of the factory was fully connected, and the pressure swing adsorption oxygen production equipment was officially put into operation.
At present, the factory production line has been running stably for nearly two years, and the enterprise has accumulated valuable experience in oxygen enriched side blowing furnace production control, flue gas environmental protection treatment, and multi metal step purification and utilization. especiallyPressure swing adsorption oxygen production equipmentThe advantages of fast start stop and flexible load adjustment have played a significant role in production practice. At the same time, the oxygen production equipment also has advanced intelligent modules such as unmanned operation and cloud management, further ensuring the safe and stable operation of the equipment. The process combination of "VPSA+oxygen enriched side blowing furnace" has been widely used in industrial applications of hazardous waste metal smelting, and is a widely recognized supporting technology with high economy and reliability in the industry.
From the perspective of economic benefits, according to user statistics, only the pressure swing adsorption oxygen production part can save more than 2 million yuan in oxygen costs annually, promoting a significant improvement in the comprehensive benefits of enterprises. In recent years, multiple comprehensive treatment projects for copper containing sludge and metal hazardous waste in China have adopted VPSA oxygen generation technology as the oxygen source, with Peking University Pioneer serving as the domestic leaderPressure swing adsorption oxygen productionA well-established manufacturer has constructed multiple sets of medium to large-scale VPSA oxygen production units for renewable resource utilization enterprises, all of which have achieved good application results, fully proving that VPSA oxygen production technology is the preferred process for oxygen assisted side blowing furnaces.
