Description

Technical Field

[0001] The utility model belongs to the technical field of hydro-generators, and particularly relates to a condensate water collection device for an air cooler of a hydro-generator set. Background Art

[0002] The air cooler of a hydro-generator set is used to cool the stator of the generator. Usually, water is used as the cooling medium. Due to the large temperature difference between the cooler and the air, a large amount of condensate water is usually generated. Under normal circumstances, the condensate water usually drops into the air duct below the air cooler and is collected through the drainage ditch at the bottom of the air duct. This open condensate water collection method will make the wall inside the air duct become damp, thereby increasing the air humidity inside the generator. And a part of the condensate water enters the generator through the air circulation of the generator set. In severe cases, it may cause the insulation of the generator components to decrease, resulting in a short circuit of the generator components, and then leading to an accident shutdown. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a condensate water collection device for an air cooler of a hydro-generator set to solve the problems existing in the prior art in view of the deficiencies of the prior art.

[0004] The technical purpose of the utility model is achieved through the following technical solutions:

[0005] A condensate water collection device for an air cooler of a hydro-generator set includes a plurality of collection components. Each collection component includes a collection box and a water outlet pipe connected to the bottom of the collection box. The collection box is used to connect with the outer shell of the air cooler, collect the condensate water of the air cooler, and discharge it through the water outlet pipe. It also includes a main drainage pipe, and the water outlet pipes of all collection components are communicated with the main drainage pipe.

[0006] Preferably, the collection box includes a bottom plate and side plates connected to three sides of the bottom plate. An ear plate is also connected to two of the side plates, and bolt holes are provided on the two ear plates for connecting with the air cooler.

[0007] Preferably, the water outlet pipe is welded to the collection box.

[0008] Preferably, the water outlet pipe is detachably connected to the main drainage pipe.

[0009] Preferably, the water outlet pipe is detachably connected to the main drainage pipe through a pipe joint.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] A condensate water collection device for a hydro-generator air cooler provided by the utility model can improve the collection efficiency of the condensate water of the hydro-generator air cooler, reduce the time of the condensate water of the air cooler exposed in the air, lower the humidity inside the hydro-generator, reduce the probability of component short-circuit of the hydro-generator, and create conditions for the civilized production of the power plant.

[0012] By adding the condensate water collection device provided by the utility model at the bottom of the air cooler and directly discharging it into the total drainage loop pipe at the bottom through a special pipeline, the original method of collecting condensate water in the drainage ditch in the wind tunnel is cancelled. In this way, the diffusion position of the condensate water can be greatly reduced through the fixed pipeline, thereby reducing the air humidity inside the generator, improving the operating environment of the generator, and ensuring the safe and stable operation of the generator.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As a preferred embodiment of the present utility model, as Figures 1 - 3 shown, this embodiment provides a condensate water collection device for a hydro-generator air cooler, including a plurality of collection components. The collection components include a collection box 1 and a water outlet pipe 2 connected to the bottom of the collection box 1. The collection box 1 is used to connect with the outer shell of the air cooler A, collect the condensate water of the air cooler A, and discharge it through the water outlet pipe 2; it also includes a total drainage pipe 3, and the water outlet pipes 1 of all collection components are communicated with the total drainage pipe 3.

[0023] After the bolt holes 13 are drilled, the condensate collection device is installed on the water turbine air cooler A using M12 bolts. After being fixed, glass glue is applied at the bottom of the condensate collection device and the air cooler as a seal to prevent the collected condensate from flowing into the wind tunnel through the gaps.

[0024] After the condensate collection device is fixed, a hole with a diameter of 15 mm is opened at its bottom for installing an outlet pipe to drain the condensate into the main drainage pipe and then centrally discharged into the plant catchment ditch B.
