Efficient corrosion resisting dust-collecting energy-saving chimney

Abstract

A high-efficiency anticorrosive dust-collecting energy-saving chimney has a chimney barrel lined a hearth spiral line. At the bottom of the chimney barrel there is an air intake in communication withthe hearth spiral line.

Description

technical field [0001] The invention relates to an anti-corrosion, dust-collecting and energy-saving chimney. Background technique [0002] In the existing chimney, the flue enters through the pipe core line of the chimney. The chimney with this structure has high resistance and no dust collection. The flue gas in the chimney rises along the inner wall of the chimney, and the flue gas corrodes the inner lining, causing the inner lining to rot and peel off, and the chimney is broken. In recent years, in order to protect the environment, sulfur dioxide, a harmful substance in the atmosphere from smelting, power generation, and chemical production, which is discharged from the chimney, is subjected to wet desulfurization before the flue gas enters the chimney, thereby reducing the temperature of the flue gas to below the dew point. However, the resulting acid liquid flows down the inner wall of the chimney, which can easily cause the lining to rot and cause the cylinder to cra...
