AI Technical Summary

Technical Problem

Existing flue gas purification equipment for silicon metal smelting furnaces suffers from serious heat waste, low cooling efficiency, and poor filtration effect, making it unable to effectively handle the heat and impurities in the flue gas.

Method used

A flue gas purification system was designed, comprising a housing, an air inlet pipe, a baffle plate, a hollow shaft, a stirring paddle, a cooling mechanism, and a filter screen. The system generates small bubbles by rotating the stirring paddle, increasing the contact area between the bubbles and the cooling water. Multiple cooling mechanisms are used to reduce the flue gas velocity. Combined with a wire mesh demister and a sedimentation tank, the system achieves efficient cooling and filtration.

Benefits of technology

It achieves efficient cooling and filtration of flue gas, reduces heat waste, improves cooling and filtration efficiency, reduces water costs for enterprises, and enhances water resource utilization.

Abstract

This utility model discloses a flue gas purification system for a silicon metal smelting furnace, including a housing and an inlet pipe. The housing is divided into a washing chamber and an inlet chamber by a partition. A hollow shaft is installed in the inlet chamber, with its lower end extending out of the housing and connected to a motor. Its upper end is sealed and extends into the washing chamber, where a stirring paddle is installed. Ventilation holes are provided on both the hollow shaft in the washing chamber and the hollow shaft in the inlet chamber. Multiple cooling mechanisms are installed above the housing. Each cooling mechanism includes a vertical cylinder and a central tube coaxially arranged within the vertical cylinder. The central tube has helical blades, which are hollow structures. The lower end of the central tube communicates with the washing chamber. A water inlet pipe is installed at the upper end of the vertical cylinder, and a water outlet pipe is installed at the lower end, extending into the upper part of the washing chamber. In summary, this utility model has the advantages of low heat waste, good cooling effect, and high filtration efficiency.
