Description

Device for automatically and stably controlling water level of condensate polishing regeneration tower

Technical Field

The utility model relates to the technical field of condensate polishing in a thermal power plant, in particular to a device for automatically and stably controlling the water level of a condensate polishing regeneration tower, which has the advantages of simple structure, convenient use and good drainage effect.

Background

As is known, in order to avoid the danger of regenerated acid liquor or alkali liquor leaking into a thermodynamic system, an external regeneration process is adopted in a high-speed mixing bed for condensate polishing in a power plant. The in vitro regeneration system generally comprises a cation resin regeneration tower (cation tower), an anion resin regeneration tower (anion tower), a mixed grease tower, a Roots blower, an acid pump, an alkali pump, a flushing water pump and the like.

After the failure resin from the mixed bed is separated, the positive resin is in the positive tower, the negative resin is in the negative tower, and a small amount of mixed resin is in the mixed resin tower. The separated failure cation resin and failure anion resin need to be respectively regenerated in acid liquor and alkali liquor with certain concentration. In order to ensure the regeneration effect, the water levels of the positive tower and the negative tower which are full of water are required to be reduced to 20-30cm on the surfaces of corresponding resins before acid and alkali are fed. In order to meet the requirement of the water level, two methods are usually used, one method is to control the water level by manually observing and operating the drain valve in time. The other is to control the water level by using a time-measuring drainage mode.

The above two ways of controlling the water level find the following problems in practical use:

1. the first method is labor-consuming and has high requirements on the quality of personnel. If the operation is not timely, the water is replenished after excessive drainage, so that water resource waste is caused, and meanwhile, the pump is damaged by frequently starting and stopping the flushing water pump.

2. The second method causes multiple rows or less rows in the same time when the drainage working condition changes, and also causes improper water level control and reduced air-water mixing scrubbing effect.
