Abstract

The invention discloses a device and a method for preventing resin leakage of fine treatment regeneration equipment, the device comprises a separation tower, a positive regeneration tower, a negative regeneration tower, a waste resin trapper and other equipment, and the functions of separation, regeneration and mixing of resin are realized. In a fine treatment resin regeneration process, the separation tower, the positive regeneration tower and the negative regeneration tower all have resin air scrubbing and backwashing processes, and when the air scrubbing water level and the backwashing water amount are inappropriately controlled, the resin is very easy to be discharged from exhaust ports at the tops of the separation tower, the positive regeneration tower and the negative regeneration tower, so that the problem of resin leakage is caused. Resin intercepting devices are arranged at exhaust ports at the tops of the separation tower, the positive regeneration tower and the negative regeneration tower, so that resin leakage is prevented. The device and the method can reduce the loss of the resin, reduce the supplement amount of the resin and save the operation cost. Meanwhile, the problem that the separation, regeneration and mixing effects of the resin are influenced due to improper operation steps caused by insufficient resin is avoided.

Description

technical field [0001] The invention relates to condensate fine treatment equipment in a thermal power plant, in particular to a device and method for preventing resin leakage from the fine treatment regeneration equipment. Background technique [0002] Both subcritical and supercritical units are designed with a condensate polishing system, in which the finishing regeneration system includes separation towers, positive regeneration towers, negative regeneration towers and waste resin traps to realize resin separation, regeneration and mixing functions. During the resin regeneration process of fine treatment, the separation tower, positive regeneration tower and negative regeneration tower all have resin scrubbing and backwashing processes. The exhaust port at the top of the tower is exhausted, causing the problem of resin leakage. [0003] After the resin leaks from the exhaust port on the top of the regeneration equipment, it can be intercepted and found by the waste resi...
