AI Technical Summary

Technical Problem

The flange connection of the existing closed cooler is easily corroded by the primary water source, which leads to unstable equipment operation. In addition, the nozzles of the cleaning device are prone to falling off and being damaged, affecting the cleaning effect and equipment safety.

Method used

Anti-corrosion layers are installed on the water chamber flange and the reverse flange, and a reinforcing cover is installed at the nozzle. Anti-corrosion metal plates are welded and bolted to fix the nozzle. The threaded connection between the nozzle and the injection main pipe is reinforced with protection.

Benefits of technology

It effectively prevents flange corrosion, improves equipment operation stability, enhances nozzle connection strength, facilitates maintenance, and increases cleaning coverage to over 95%.

Abstract

The closed cooler with the cleaning device comprises an integrated water chamber, a water chamber flange is arranged on the integrated water chamber, the water chamber flange is in butt joint with a counter flange, a shell connecting structure is arranged on the counter flange, and the shell connecting structure is used for being connected with a shell of the closed cooler. A water chamber flange anti-corrosion layer and a counter flange anti-corrosion layer are laid on the surface of the water chamber flange and the surface of the counter flange respectively, and the water chamber flange anti-corrosion layer and the counter flange anti-corrosion layer are used for preventing the water chamber flange and the counter flange from being corroded by media in the integrated water chamber. The closed cooler with the cleaning device has the advantages that the water chamber flange anti-corrosion layer and the counter flange anti-corrosion layer are laid on the water chamber flange and the counter flange respectively, and the water chamber flange and the counter flange can be effectively prevented from being corroded by media in the integrated water chamber; moreover, the cleaning device adopts a reinforcing cover and a second-section nozzle to reinforce the nozzle, so that the nozzle is prevented from damaging a threaded hole, and the maintenance is convenient.
