Abstract
The utility model discloses a circulating water cooling system for a power plant, which comprises a water circulating pump (2), a steam condenser and a natural draft cooling tower (1) that are sequentially connected through a circulating water pipeline (3), wherein circulating water in the circulating water pipeline (3) enters the natural draft cooling tower (1) for heat exchanging after being heated by the steam condenser; the cooled circulating water drops into a bottom pool and flows out through the water circulating pump (2); and the water circulating pump (2) is arranged at the bottom of the natural draft cooling tower (1) and between two water distributing troughs. The water circulating pump (2) is a vertical diagonal flow pump. With the adoption of the arrangement, the floor area and the circulating water pipeline are saved without affecting the normal operation of the circulating water cooling system.
Description
Technical field
The utility model relates to the cooling system in thermal power plant, refers in particular to a kind of circulating water cooling system that cooling stack is arranged.
Background technology
The circulation in thermal power plant adopts the secondary circulation cooling system of band cooling stack more; The basic procedure of this system is: water circulating pump → circulating water pipeline → condenser → circulating water pipeline → cooling stack, recirculated water circulates in this cooling system.
This system is driven into low-temperature circulating water in the condenser through water circulating pump; In condenser, carry out heat exchange with the steam of being discharged by steam turbine, be condensed into water to steam, low-temperature circulating water is heated; The high temperature circulation water that flows out is sent in the water distribution system of cooling stack through circulating water pipeline; Be transported to central vertical shaft through water supply pipeline, be assigned to distribution channel, by the aperture on the distribution channel water is sowed at filling surface equably again; The air of dry low break value is got in the tower by the bottom under the effect of blower fan; The high temperature circulation current when filling surface, form moisture film and air carries out heat exchange; The hot blast of the high break value of high humility is extracted out from the top, and the recirculated water that is cooled splashes in the pond, bottom, flows out through circulating water pipeline.
At present, water circulating pump mostly is arranged in the circulating pump room, and floor space is bigger, and because the requirement of minimum range is arranged between cooling stack and other building, often makes that the circulating water pipeline distance is longer, increases the circulating water pipeline cost.
The utility model content
The technical problem that the utility model mainly solves provides a kind of saving floor space, the arrangement of economized cycle waterpipe.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of generating plant circulation-water cooling system of the utility model comprises the water circulating pump 2, condenser, the cooling stack 1 that are connected successively by circulating water pipeline 3; In the tower body center of circle of cooling stack 1 central vertical shaft 4 is set, on through the tower body radius of a circle of central vertical shaft 4, arranges distribution channel 5; Wherein said water circulating pump 2 is arranged in the cooling stack 1.
The concrete scheme of the utility model is: said water circulating pump 2 is arranged in the bottom of cooling stack 1, the position between two distribution channels.
The further improvement of the utility model is: said water circulating pump is two, and is arranged symmetrically in the both sides of cooling stack 1 an interior distribution channel.
The further improvement of the utility model is: said water circulating pump 2 is vertical diagonal flow pump.
Owing to adopted technique scheme, the technological progress that the utility model is obtained is:
Be placed on water circulating pump in the cooling stack in the secondary circulation cooling system in thermal power plant; Through such layout; Water circulating pump directly from the suction of cooling tower bottom, not only reduce the recirculated water pump lift, and cooling tower can be arranged outside main building nearby; The economized cycle waterpipe is saved floor space.
Adopting the arrangement economical rationality of the utility model, is trickle area 3500m like construction scale
2The circulating cooling system of cooling stack, adopt the mode of arranging in the water circulating pump tower than about 1,200,000 yuan of the conventional arrangement saving investment that has circulating pump room and operating cost.
Water circulating pump is arranged between two distribution channels, and so neither influence is normal uses, away from the trickle district, safe and reliable again.
Water circulating pump adopts vertical diagonal flow pump, owing to be the vertical pump housing, can reduce the flowing resistance in the tower, reduces to minimum to the influence of blowing in the tower.And this pump is simple to operate in work progress, is convenient to install.

Fig. 2 is the cooling stack cross section along I among Fig. 1-the I line is got.
Wherein: 1, cooling stack, 2, water circulating pump, 3, circulating water pipeline, 4, central vertical shaft, 5, distribution channel, 6, motor.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Can be found out that by Fig. 1 and Fig. 2 a kind of generating plant circulation-water cooling system of the utility model comprises cooling stack 1, water circulating pump 2, condenser, they are connected by circulating water pipeline 3; The tower body center of circle of cooling stack 1 is provided with central vertical shaft 4, on through the tower body radius of a circle of central vertical shaft, arranges 4 distribution channels 5, and per two adjacent distribution channels are rectangular.Said water circulating pump 2 is arranged in the cooling stack 1, and motor 6 is arranged on the water circulating pump 2.The circulating water cooling system of the utility model is in running; Low-temperature circulating water is driven in the condenser through water circulating pump 2; In condenser, carry out heat exchange with the steam of being discharged by steam turbine, the high temperature circulation water that from condenser, flows out is sent into through circulating water pipeline 3 in the water distribution system of cooling stack 1, is transported to central vertical shaft 4 through water supply pipeline; And be assigned to distribution channel 5, by the aperture on the distribution channel 5 water is sowed at filling surface equably again; Recirculated water carries out heat exchange with the air that gets in the tower, and the recirculated water that is cooled splashes in the pond, bottom, is got by the water circulating pump 2 of tower bottom.
With the trickle area is 3500m
2Cooling stack be example; The tower bottom diameter is 72m; The diameter of water circulating pump 2 and motor 6 is about 3m; 2 water circulating pumps are set in the bottom of cooling stack, and every water circulating pump 2 is arranged in two positions between the distribution channel, and two water circulating pumps are arranged symmetrically in the both sides of a distribution channel.Water circulating pump 2 adopts vertical diagonal flow pump.Through such layout, under the situation that does not influence normal use, can reduce the flowing resistance in the tower.
Water circulating pump arranges in cooling tower, and the harmonious property with civil engineering should attention equipment be installed, and the position of water circulating pump can be adjusted the position as required.
