Haihui Group’s New Generation Low-Resistance Dust Collector: A Proven Solution for Electric Furnace Flue Gas Treatment

Drawing on years of extensive experience gained from numerous electric furnace flue gas treatment projects, Haihui Group’s Dust Collection Division has developed a profound understanding of the technologies involved in the capture, conveyance and purification of high-temperature flue gas. Building on a thorough understanding of the operational characteristics of various electric furnaces, the division’s technical team has successfully developed and upgraded a new generation of low-resistance dust collectors, incorporating optimised low-resistance designs for the ductwork system. During actual operation, this equipment has demonstrated outstanding advantages such as high dust removal efficiency, low operating resistance and low energy consumption, earning the praise and trust of a wide range of customers.

Process Description

The complete process for electric furnace flue gas treatment is as follows: dust-laden flue gas generated during smelting is first effectively contained within a large, mobile, fully enclosed furnace hood, minimising fugitive emissions. Driven by an induced draught fan, the dust-laden gas stream first enters a heat exchanger for cooling, adjusting the high-temperature flue gas to the appropriate operating temperature range for the baghouse dust collector. Subsequently, the cooled flue gas enters the electric furnace baghouse dust collector for deep purification. The clean flue gas, having passed through the filter bags, is discharged into the atmosphere via the induced draught fan. The dust intercepted by the filter bags accumulates in the ash hopper and is periodically discharged via an ash discharge device for separate centralised treatment, ensuring that secondary pollution is kept under control.

System Configuration and Services

This electric furnace dust collection system employs an advanced fan power system and is equipped with system control and adjustment solutions tailored to meet the diverse needs of different users. With energy conservation, reduced consumption and long-term low-cost operation as its core design philosophy, Haihui Group provides clients with high-standard, one-stop services. These encompass comprehensive support throughout the entire process, including customised design, equipment manufacturing, on-site installation, system commissioning and operational management guidance, ensuring the long-term stable, efficient and economical operation of the dust collection system.
