Hunan RE Technology Co. Ltd. products

Acid production systems are integral to various industries, facilitating the creation of essential chemicals used in manufacturing, agriculture, and more. These systems encompass a range of technologies and processes designed to produce different types of acids efficiently and safely. We recommend the combination of ionic liquid desulfurization and industrial sulfuric acid process to treat the lead smelting flue gas to meet the standard emission and produce industrial sulfuric acid. Side-blown furnace flue gas purification: adopt adiabatic evaporation dilute acid cooling process, side-blown furnace flue gas purification into the automatic gas separatic system to automatically adjust the amount of gas to be divided, 50% of the flue gas into the composite amine SO2 capture desulfurization system, 50% of the flue gas intc turn one-suction acid production system

in order to realize the clean utilization of hazardous wastes with heavy metals and organic substances, RE TECH has developed a unique low-temperature pyrolysis technology for organic hazardous wastes, which can be widely used in the resource treatment and harmless recycling of waste enamel wires, waste circuit boards, waste tires, and waste lithium batteries with the core equipment of the steel belt-type low-temperature pyrolysis furnace. The technology adopts anaerobic pyrolysis to carry out comprehensive recovery, avoiding the production of a large number of hazardous substances generated by direct incineration, while at the same time, all the organic matter will be converted into reusable products, realizing the recycling of hazardous wastes, and completely solving the problem of environmental pollution in the process of recovery of such resources.

The principle of fuming is a reduction and volatilization process, which is to blow air and pulverized coal into the slag in the fuming furnace, generate heat and carbon monoxide after combustion, keep the slag at high temperature, and make the compounds and free ZnO and PbO in the slag reduced to Zn and Pb vapors, the vapor will rise to the upper space of the furnace, meet CO2 or inhaled air and oxidize to zinc oxide and lead oxide again, and are collected in the state of soot.

This series of patented equipment developed by our company in cooperation with Central South University is mainly adopted to treat arsenic alkali slag, arsenic filter cake, and other arsenic contented materials from copper smelter.lead smelter and zinc smelters. The main process is: hydrometallurgy + pyrometallurgy combined to turn the arsenic-containing hazardous wastes into pure arsenic trioxide, and then reduced to metallic arsenic, metallic arsenic can be sold according to local market demand or rigid landfill disposal. The main patented equipment of this process, AS2O3 purification furnace and arsenic reduction furnace, is widely praised for its high level of environmental protection.
