Comprehensive utilization project of purified ash return to furnace incineration in the calcium carbide industry

The calcium carbide purification dust generated during the production process of raw material calcium carbide has become a challenge for enterprises to cope with environmental pollution and safety production due to its small fineness, high toxicity, flammability and explosiveness. Shandong Zhanggu Pneumatic Conveying Engineering Company has successfully solved this problem for the enterprise by adopting nitrogen circulation conveying technology.

By designing a system for circulating purified ash nitrogen gas back to the furnace for combustion and slag recycling, the purified ash containing some calorific value is collected by a pneumatic conveying device and sent as auxiliary fuel to the boiling furnace for combustion and utilization. The slag produced after incineration in the boiling furnace is collected and recycled after cooling.

This project can process solid waste for enterprises, save standard coal for users after recycling, and directly generate economic benefits. At the same time, in order to solve environmental problems for the company, the particulate matter of the project system has basically achieved zero emissions, greatly exceeding the latest national emission standard for solid waste pollutants of less than 10mg per cubic meter.
