Description

Desulfurization and demisting flushing water system with communicating pipe

Technical Field

The utility model relates to a power plant's desulfurization technique specifically is a desulfurization defogging wash water system with closed tube.

Background

Because the existing desulfurization absorption tower process water systems of various power plants are generally designed into two process water pumps, one is used for transportation and the other is used for standby, and the main functions of the process water systems are to provide machine seal cooling water or desuperheating water for main key equipment such as a circulating pump, a jet pump, a slurry discharge pump, an oxidation fan and the like. Because the mechanical seals of main desulfurization equipment such as a circulating pump jet pump and the like are water-cooled, when water is cut off for more than 3 minutes, the mechanical seals are damaged due to high temperature generated by high-speed rotation, slurry leakage is caused, the equipment is stopped, and a desulfurization system and even the whole boiler unit can be stopped when the equipment is seriously stopped. Therefore, the process water pump running pump and the standby pump are interlocked, and the standby equipment can be immediately started in an interlocked manner when the running equipment is damaged and stopped.

However, in the traditional desulfurization and demisting washing water system on the market, the process water pump and the demisting water pump are relatively independent, and cooling water cannot be provided for key equipment when the process water pump fails, so that the whole boiler unit is stopped.
