Abstract
The utility model relates to a direct forced air cooling of air cooling recirculated cooling water is cooling system again at need cooling equipment external connection air cooling cooling back installation, links to each other through the pipeline and loops in, and air cooling cooling back installation accesss to and sets up first valve on the pipeline that needs the cooling device to and and parallelly connected at least one air -cooled refrigeration and cooling device that sets up of this first valve, set up the second valve before the air -cooled refrigeration and cooling device, first valve and second valve connection control device, the utility model has the advantages of the system is simple, the operational check is convenient, satisfy the droughty and water lack areas needs that recirculated cooling water cools down again under summer extremely hot weather operating mode.
Description
Technical field
This utility model belongs to the power plant cooling down system again that drought and water-scarce area is suitable for.
Background technology
In drought and water-scarce area, especially extreme dehydration area, the feature of summer climate is daytime temperature height, nighttime temperature
Low, day and night temperature is big.Part in this region has the industrial undertaking of the very big equipment of heat dissipation capacity, for ensureing the production peace of enterprise
Row for the national games, need to carry out cooling process by great equipment to heat dissipation capacity, to reach the safe operating temperature of equipment itself.For example generate electricity
Steam turbine in factory and the converter valve cooling system in subsidiary engine blood circulation, extra-high voltage DC transmission system DC current conversion station etc..Right
Drought and water shortage, especially extreme dehydration area, cooling recirculation system typically adopts air cooling system (also referred to as air cooling system), conventional big
The cooled temperature of type air cooling system interior circulation water is high 7～8 DEG C generally than outside atmosphere temperature.Because of extreme arid torrid climate Area during Summer
Meteorological condition is special, and the temperature on daytime is higher, often exceeds more than 32 DEG C so that the coolant-temperature gage after air cooling system cooling is at 39 DEG C
More than, require cooling inflow temperatures to have a special installation of safety requirements less than 38 DEG C for some, cooling water enter water temperature
Degree has exceeded the maximum safety temperature of its safe operation, need to carry out cooling further and process so as to the inflow temperature of recirculated water is low
Below safe temperature required by equipment, the normal operation that guarantee produces.Recirculated cooling water cools equipment from need
Draw and after air cooling cooling back installation cools down, if the temperature of its recirculated cooling water remains above cooled cooling system institute
During the highest safety value that need to lower the temperature with recirculated cooling water inlet temperature, could meet, after process of need to lowering the temperature again, the cooling system that is cooled
Safe operation require.
Generally, the mode processing frequently with water-spraying evaporation cooling of lowering the temperature again of recirculated cooling water, but in drought and water shortage, especially
It is extreme dehydration area, caloric value is larger, need the lower the temperature further system of process of recirculated cooling water to be or should not to prohibit the use of spray
The mode of water cooling, some areas are at all anhydrous to be gone to carry out spraying water, sprays to reach the purpose that evaporation cools.
In addition, because the outdoor temperature of hot arid area summer day higher so that air cooling cooling back installation cooling after
Recirculated cooling water temperature higher, under this operating mode, conventional refrigeration unit (includes electrical chillers and lithium bromide refrigerator
Group) cannot run；Again because BrLi chiller requires to the cooling environment of cooling system, at present all using water cooling
Mode, the operation and Wind-cooling type BrLi chiller does not also put into production.Therefore, for reducing hot, arid, water-deficient area summer
The water consumption of recirculating cooling water system, BrLi chiller is not suitable for recirculation cooling water cooling system again.
Utility model content
The technical problem that this utility model is solved is i.e. in the air cooling circulating cooling providing a kind of drought and water-scarce area to be suitable for
Water directly air-cooled cooling down system again.
The technological means that this utility model is adopted are as follows.
A kind of air cooling recirculated cooling water directly air-cooled cooling system again, need cool device external connect air cooling circulation
Chiller, is connected to form loop by pipeline, and described air cooling cooling back installation leads on the pipeline needing cooling device
It is arranged in parallel air cooling refrigeration cooling system.
Described air cooling refrigeration cooling system comprises at least one air cooling refrigeration heat sink.
Beneficial effect produced by this utility model: simple system, run easy to control, meet drought and water-scarce area in the summer
The needs that under Ji Jiduan sweltering heat weather operating mode, recirculated cooling water is lowered the temperature again.
Brief description
Fig. 1 is the schematic diagram of the direct air-cooled cooling system again of air cooling recirculated cooling water of the present utility model.
Specific embodiment
This utility model protection is applied to the air cooling recirculated cooling water directly air-cooled cooling system again of drought and water-scarce area.As
Shown in Fig. 1, cool equipment 1 external connection air cooling cooling back installation 2 in need, loop is connected to form by pipeline.This reality
Focused on new, lead in air cooling cooling back installation 2 be arranged in parallel on the pipeline need cooling device 1 air-cooled
Refrigeration cool-down system 3, this air cooling refrigeration cooling system 3 comprises at least one air cooling refrigeration heat sink, can be according to actual rings
Border and use demand determine the quantity of this device, and here no longer specifically limits.
Valve 4 is set on output channel 21, it is located between the gateway of air cooling refrigeration cooling system 3, defeated for controlling
Go out the flow of pipeline 21 recirculated cooling water, setting valve 5 before air cooling refrigeration cooling system 3, for controlling entrance air-cooled
The circulating cooling water flow of self cooling cooling system 3.Two valves use cooperatively the assignment of traffic controlling recirculated cooling water.
When actually used, the high temperature circulation cooling water after needing cooling device 1 heat absorption to heat up flow to air cooling circulation
Chiller 2 carries out cooling down, then flows back and the need equipment of cooling is lowered the temperature.When outside is extremely hot weather
During special operation condition, high-temperature cooling water is lowered the temperature but not up to required cooling water temperature by air cooling cooling back installation 2, that is, being higher than need to be cold
But the highest safety entrance temperature of heat sink 1, closes valve 4 and opens valve 5, directly passes through the air-cooled system of specific form
After cold cooling system 3 cooling, make cooling water reach temperature required requirement, that is, be equal to or less than highest safety entrance temperature, then
Entrance need to cool in equipment 1.
The setting of directly air-cooled cooling system more of the present utility model, simple system, run easy to control, meet arid and lack
The water area needs that recirculated cooling water is lowered the temperature again under summer extremely hot weather operating mode.
