Background technology
With the development of China's solar power generation and wind-power electricity generation, generation of electricity by new energy accounts for the ratio of gross generation increasingly
Greatly, the requirement to traditional thermal power generation depth peak regulation is higher and higher.Existing octet formula accumulation of heat water pot water distributor, using water distributor
The form of upper trepanning.The water distributor of such form, actual internal area is small, is easy to block.Water distributor is discharged along accumulation of heat water pot height
Direction has component velocity, thermocline thickness to increase.Water distributor structure is complicated simultaneously, and consumptive material is more, and processing and installation required precision is high, at
This is higher.
Invention content
The purpose of the present invention is to provide it is a kind of it is simple in structure, at low cost, shunting water distribution, water flow velocity is low, water distribution is uniform, no
Block, effectively reduce the thermoclinic thickness of accumulation of heat water pot, suitable for large-scale accumulation of heat water pot water distribution thermal power plant's depth peak regulation it is flexible
Property hold over system accumulation of heat water pot water distributor.
In order to achieve the above object, thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, packet
Lower water distribution plectane is included, the guiding cone that on lower water distributing plate and top is cylindrical, lower part is tapered is mounted on, in guiding cone week
Arranged for interval, convex and in guiding cone and lower water distributing plate split-flow baffles are enclosed, are mounted on split-flow baffles protrusion
The upper water distribution plate body in face is mounted on the shaped Nozzles of split-flow baffles protrusion side, connects between upper water distribution plate body and shaped Nozzles
The baffle liner connect, in the water distributor of shaped Nozzles upper end link.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, the upper water distribution plate body, under
It is supported by split-flow baffles between water distribution plectane and forms multiple independent water distribution cavitys.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, the upper water distribution plate body,
Positive pitch is 0 °~10 °.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, when can be electricity consumption high load capacity on daytime
Heat production stored in the form of hot water, heat releases heat supply user use when night electricity consumption underload, so that thermoelectricity is decoupled, reaches
To the purpose of depth peak regulation.Accumulation of heat water pot can coordinate electric boiler to use simultaneously, and electric energy is converted into thermal energy storage in trough-electricity
It stores away, heat supply use when for peak electricity.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, accumulation of heat water pot are using water as storage
Can medium energy storage equipment, carry out natural layering using the difference of the density of hot and cold water, hot water storage is cool on accumulation of heat water pot top
Water is stored in accumulation of heat water pot lower part, and the place of intermediate hot and cold water transition is mesolimnion.Core of the water distributor as accumulation of heat water pot
Part, design play the role of the thermoclinic thickness of accumulation of heat water pot vital.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, operation principle are：Work as flow
When entering accumulation of heat water pot by water distributor, flow enters water distributor by the water distributor with external connection, into shaped Nozzles, stream
Logical sectional area becomes larger, and water flow velocity reduces.By split-flow baffles, flow is divided equally, and is then entered under by the water conservancy diversion of baffle liner
Several independent water distribution cavitys that water distributing plate, upper water distribution plate body and split-flow baffles are formed, flow velocity further decreases, into accumulation of heat
In water pot body.When flow flows out accumulation of heat water pot by water distributor, the water in accumulation of heat water pot is uniformly only by several first
Vertical water distribution cavity, then enters shaped Nozzles by the water conservancy diversion of baffle liner, and by the cooperation with guiding cone, flow converges,
Water distributor is flowed out by water distributor.
Thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, simple in structure, at low cost, flow
Channel design transition is round and smooth, and no mutation, actual internal area is big, does not block, and water flow velocity is low, and water distribution is uniform.Water distributor disengaging simultaneously
Water is small in vertical direction component velocity, can effectively reduce the thermoclinic thickness of accumulation of heat water pot, is suitable for large-scale accumulation of heat water pot water distribution.
In conclusion thermal power plant's depth peak regulation flexibility hold over system accumulation of heat water pot water distributor of the present invention, simple in structure, at
This is low, shunts water distribution, and water flow velocity is low, and water distribution is uniform, does not block, and effectively reduces the thermoclinic thickness of accumulation of heat water pot, is suitable for big
Type accumulation of heat water pot water distribution.
