Abstract
The utility model discloses a circulating water cooling device of a hydraulic turbine generator unit in a hydropower station, which is composed of a machine set, a circulating water pool, a circulating water pump and a circulating water cooler; the circulating water cooler is formed by connecting two coolers by a flange plate and a bolt; the coolers are communicated with side walls of an upper branched pipe and a lower branched pipe by two end heads of radiating pipes which are arranged in both sides of the branched pipes closely; one end of the branched pipe is fixedly communicated with a side wall of a main pipe; the other end of the upper branched pipe is connected with the flange plate of the branched pipe which corresponds to the cooler by the flange plate; the other end of the lower branched pipe is communicated with the flange plate of the branched pipe which corresponds to the cooler by the flange plate; a main pipe on one side of the cooler is provided with a water inlet, and the main pipe on the other side of the cooler is provided with a water outlet; and the circulation cooler is fixed in a water tank by using a lifting lug and a foundation bolt. The circulating water cooling device of the hydraulic turbine generator unit in the hydropower station reduces the temperature of hot water in the cooler by using the flowed river water so as to reach the quality requirement of circulating water and guarantee the safe running of the machine set.
Description
Technical field:
The utility model belongs to the circulating water cooling device of generator and transformer cooling water in the water power plant.
Background technique:
Water supply mainly is to be generator and transformer cooling water in the water power plant, the reliability that cooling is supplied water and the quality of water have very big influence to the normal operation in power station, generally adopt before the dam or spiral case water intaking or downstream water intaking, such water supply is vulnerable to the influence of silt and floating debris, quality of water supply is difficult to guarantee, so need be improved.
The model utility content:
The purpose of this utility model provides the water power plant hydraulic generator unit circulating water cooling device of hydropower generator and transformer cooling water.
Technical solutions of the utility model as shown in Figure 1, water power plant hydraulic generator unit circulating water cooling device is made up of unit 1, circulating water pool 2, circulating water pump 3, unit 1 water outlet water pipe is connected with circulating water pool 2, circulating water pump 3 feed-water end water pipes are connected with circulating water pool 2, circulating water pump 3 waterexit end water pipes are connected with the water intake 13 of recirculation cooler 4, and water outlet 14 water pipes of recirculation cooler 4 are connected with unit 1 water intake.Recirculation cooler 4 is seen Fig. 2, shown in Figure 3, be to connect to form with flange plate 12 and bolt in the middle of cooler 5 and the cooler 6, cooler 5 or cooler 6 are that the two ends by the heat dissipating pipe 7 that is closely packed in arm 8 both sides is communicated with elevation by-pass 8 sidewalls, one end of arm 8 fixedly is communicated with house steward's 9 sidewalls, the other end of top arm 8 is by flange plate 12 connections of the corresponding arm 8 of flange plate 12 and cooler 6, the other end of below arm 8 is by flange plate 12 connections of the corresponding arm 8 of flange plate 12 and cooler 6, the top house steward 9 of cooler 5 is provided with water intake 13, the top house steward 9 of cooler 6 is provided with water outlet 14, and the both sides, top of recirculation cooler 4 are provided with hanger 10 and the bottom is provided with stone bolt 11.
Recirculation cooler 4 is placed in the streamway, as shown in Figure 4, be fixed in the tank of specializing in by hanger on the recirculation cooler 4 10 and stone bolt 11, after the circulating water that has temperature enters water intake 13, hot water is discharged by water outlet 14 by arm 8, house steward 9 through heat dissipating pipe 7, the coolant-temperature gage that discharge this moment is reduced to the requirement of satisfying unit 1 water temperature, flows into the cooling water that unit 1 cools off again and flows back to circulating water pool 2 again, just can be recycled.
According to the needs of water power plant cooling, many group recirculation coolers 4 can be set in the unit.

Wherein: 1, unit; 2, circulating water pool; 3, circulating water pump; 4, recirculation cooler; 5, cooler; 6, cooler; 7, heat dissipating pipe; 8, arm; 9, house steward; 10, hanger; 11, stone bolt; 12, flange plate; 13, water intake; 14, water outlet.
Embodiment:
The utility model is implemented by technique scheme, the available steel pipe specification of the heat dissipating pipe of recirculation cooler has specifications such as Φ 32 * 3～Φ 45 * 3,600～1000 of one group of nearly heat dissipating pipes of cooler, house steward and arm adopt Φ 325 * 8, Φ 273 * 8, specifications such as Φ 159 * 6, Φ 75 * 4.
The recirculation cooler 4 of water power plant hydraulic generator unit is to be placed in the river to specialize in the tank as shown in Figure 4, and the water of effluent stream comes the heat radiation of cooling heat dissipation pipe, makes that hot water turns cold in the pipe, utilizes the suspension hook on four jiaos of the recirculation coolers and the stone bolt of below to fix.Hydropower Plant 1 cooling water enters water intake 13 after the house steward 9 of cooler 5 flows to each top arm 8, pass through flange plate 12 through heat dissipating pipe 7 by below arm 8, enter the below arm 8 of cooler 6, flow into top arm 8, be pooled to house steward 9 through heat dissipating pipe 7 again by water outlet 14 outflows, finished a cooling procedure, the heat of cooling water is taken away by river, guarantees that unit 1 normally moves, and unit 1 cooling water has formed circulating water.But this hydraulic generator unit circulating water cooling device is energy saving both, can guarantee the quality of using of generator and transformer again, safe operation.
