Description

Technical Field

[0001] The utility model relates to a scouring-resistant water tank structure of a gas cooler. Background Art

[0002] The steel mill currently uses dry dust removal technology for primary dust removal. The gas cooler is a key equipment and facility for gas recovery. Failure will cause the gas to be unable to be recovered for a long time, directly affecting the economic benefits of the steel mill and accompanied by potential safety hazards. The lower water tank of the gas cooler is made of patchwork welding. When recovering the gas, the cooling water is turned on for cooling. Due to the material and welding process of the lower water tank, the welds of the lower water tank are constantly eroded and corroded under the intermittent scouring of the cooling water, and the welds at the annular seam of the lower water tank leak. Long-term leakage will further aggravate the erosion and corrosion of the cooling water welds, resulting in leakage of the lower water tank during the gas recovery stage and gas leakage during the release stage. Summary of the invention

[0003] The utility model aims to provide a scouring-resistant gas cooler water tank structure, which can prolong the service life of the cooler water tank and prevent gas leakage.

[0004] The technical solution adopted by the utility model is a scour-resistant gas cooler water tank structure, including a water tank body, an inverted cone shell is arranged in the water tank body, the inverted cone shell is a stainless steel shell, a drain pipe is vertically fixed at the bottom center of the inverted cone shell, the upper end of the drain pipe is 40cm higher than the bottom center of the inverted cone shell, a circle of annular water baffle is arranged in the top surface of the water tank body, and the distance between the annular water baffle and the top end of the inverted cone shell is 2m.

[0005] By analyzing the parts with frequent water leakage and combining the on-site structural conditions, the original structure was modified: 1. The material of the lower water tank was changed to stainless steel to increase the service life. 2. The return pipe was lengthened by 40cm to ensure that there was always water accumulation at the cone-mouth weld of the lower water tank, reducing the erosion and rust of the welding seam by cooling water. 3. A circle of annular water baffles was added at a height of 2m from the upper cone surface of the lower water tank to ensure that the cone surface of the lower water tank and the tank body weld were no longer impacted by water flow, reducing the erosion and rust of the welding seam by cooling water. BRIEF DESCRIPTION OF THE DRAWINGS
