Anti-corrosion dust collection energy-saving chimney

Abstract

The invention discloses an anti-corrosion dust collection energy-saving chimney, which can solve the problems of high cost and poor turbulence effect, caused by the fact that the conventional chimney solves the problem of corrosion of a cylinder body by assembling an inner sleeve. The anti-corrosion dust collection energy-saving chimney comprises a chimney cylinder body; a plurality of turbulence ribs with a lift angle alpha are arranged on the inner wall of the chimney cylinder body; the lift angle alpha is more than 0 degree and is equal to and less than 90 degrees; an outlet of an arc flue on the outer face at the lower end of the chimney cylinder body is communicated with the turbulence ribs; each two adjacent turbulence ribs are arranged in the same direction; the height of each turbulence rib is increased along with the horizontal height of the chimney cylinder body; and the height Hh that the turbulence rib with a higher horizontal height protrudes from the inner wall of the chimney cylinder body to the center of the chimney cylinder body is less than or equal to the height HL of the turbulence rib with a lower horizontal height protruding from the inner wall of the chimney cylinder body to the center of the chimney cylinder body. The anti-corrosion dust collection energy-saving chimney provided by the invention has the advantages of high structural stability, good flow guide effect, and uniform smoke disturbance; and a great number of materials can be saved.

Description

technical field [0001] The invention relates to an anti-corrosion, dust-collecting and energy-saving chimney. Background technique [0002] In recent years, in order to protect the environment, the flue gas containing harmful sulfur dioxide produced by smelting, power generation, chemical industry and other industries has been subjected to wet desulfurization before it enters the chimney, so that the temperature of the flue gas will drop below the dew point; but the resulting acid The liquid flows down the inner wall of the chimney, which can easily cause the inner lining to rot and cause the cylinder to crack. [0003] To solve this problem, the general method is to install an inner sleeve in the chimney. But such inner sleeves are expensive. For example, the 210-meter chimney of a 600,000-kilowatt thermal power plant needs 10 million yuan for the inner cover investment, and the flow disturbance effect is not good, and this method is only a measure for easy replacement, a...

Problems solved by technology

[0004] In order to overcome the problems of high cost and poor flow-disturbance effect of the existing chimney by installing an inner sleeve to solve the corrosion problem of the cylinder, the present invention aims to provide an anti-corrosion and dust-collecting energy-saving chimney, which is relatively cheap in cost. It has the functions of anti-corrosion, dust collection and energy saving
