Abstract

The application relates to the technical field of waste gas treatment, and discloses an energy-saving alkali liquor spraying tower and application of the energy-saving alkali liquor spraying tower in steel wire heat treatment, wherein the energy-saving alkali liquor spraying tower comprises a tower body, an air inlet pipe fixedly arranged on the inner wall of the tower body, a connecting pipe fixedly arranged on the outer wall of the top of the tower body, a grid fixedly arranged on the inner wall of the tower body, a filler frame fixedly arranged on the inner wall of the tower body, and a spraying pipe fixedly arranged on the inner wall of the tower body, characterized in that the energy-saving alkali liquor spraying tower further comprises a mounting hole formed in the side wall of the tower body, a tower plate assembly fixedly arranged on the inner side wall of the tower body, and a bubble cap assembly slidingly arranged on the inner side wall of the tower plate assembly; the air passage aperture is adjusted through linkage extrusion of a servo motor and a rubber pipe, so that different airflow pressure and flow speed working conditions in the tower are matched, thereby flexibly adjusting and controlling the air path damping, the problem that waste gas flow speed is too fast to cause incomplete purification is avoided, and the problem that airflow accumulation affects treatment flux is prevented.
