Description
Technical field
The utility model relates to field of cooling tower more particularly to a kind of preventing freeze in winter induced cooling tower systems.
Background technique
Currently, induced cooling tower is the pith of power plant's cold end system, cooling efficiency influences in condenser
Vacuum degree, and then influence the thermal efficiency of cycle of entire therrmodynamic system.Cooling tower water distribution system whether rationally with the height of cooling efficiency
It is low closely related.
Common mechanical draft tower is arranged in pairs or groups water system using blower forced ventilation, but north cold area winter temperature compared with
Low, cooling tower icing will form larger harm, and air inlet, which freezes, will make incoming air area reduce to influence the cooling of cooling tower
Effect increases the loading of structure after icing, reduce structure service life.
Therefore, there are also to be developed for the prior art.
Utility model content
Place in view of above-mentioned deficiencies of the prior art, it is logical that the purpose of this utility model is to provide a kind of preventing freeze in winter machine powers
Cooling Tower system, it is intended to solve existing induced cooling tower because weather cold icing effect cooling effect reduces cooling tower
The problem of service life.
In order to achieve the above object, the utility model takes following technical scheme:
A kind of preventing freeze in winter induced cooling tower system, including induced cooling tower, butterfly valve, heat exchanger, water drenching
Device, circulating water inlet, circulating water outlet pipe, the heat exchanger is located at around the induced cooling tower, described to follow
Ring water water inlet pipe is divided into first circulation water water inlet pipe and second circulation water water inlet pipe, the first circulation water water inlet pipe and the leaching
It is equipped with first butterfly valve between water installations, second butterfly valve, institute are equipped between the second circulation water water inlet pipe and the heat exchanger
It states heat exchanger and is parallel to the induced cooling tower, the heat exchanger is connect with the circulating water outlet pipe, the heat
Third butterfly valve is equipped between exchanger and the circulating water outlet pipe.
Further, the heat exchanger is shutter form, or mobile door form.
The utility model compared with prior art the utility model has the advantages that the utility model using butterfly valve control first circulation water into
First circulation water water inlet pipe is closed when weather cold and closes cooling tower water inlet by water pipe and second circulation water water inlet pipe
Pipe opens heat exchanger pipeline, is cooled down using surface-type heat exchange to water, prevents industrial circulating water from directly connecing with cold air
Touching, prevents cooling tower from freezing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of preventing freeze in winter induced cooling tower system provided by the embodiment of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It should be noted that it can be directly another when element is referred to as " being fixed on " or " being set to " another element
On one element or it may be simultaneously present centering elements.When an element is known as " being connected to " another element, it can
To be directly to another element or may be simultaneously present centering elements.
It is only each other relatively it should also be noted that, the positional terms such as left and right, upper and lower in the utility model embodiment
Concept or be reference with the normal operating condition of product, and should not be regarded as restrictive.
As shown in Figure 1, be a kind of preventing freeze in winter induced cooling tower system of the utility model specific embodiment,
Including induced cooling tower 1, heat exchanger 3, liquid distribution 4, butterfly valve, circulating water inlet, recirculated water water outlet
Pipe, the heat exchanger 3 is located at around the induced cooling tower 1, the circulating water inlet be divided into first circulation water into
Water pipe 5 and second circulation water water inlet pipe 6 are equipped with first butterfly valve between the first circulation water water inlet pipe 5 and the liquid distribution 4
21, second butterfly valve 22 is equipped between the second circulation water water inlet pipe 6 and the heat exchanger 3, the heat exchanger 3 is parallel to
The induced cooling tower 1, the heat exchanger 3 are connect with the circulating water outlet pipe 7, the heat exchanger 3 with it is described
Third butterfly valve 23 is equipped between circulating water outlet pipe 7.
Specifically, the heat exchanger 3 is shutter form, or mobile door form.
Heat exchanger 3 is increased around the induced cooling tower 1, with the water drenching in the induced cooling tower 1
Device 4 forms parallel system, and the second circulation water water inlet pipe 6 of induced cooling tower 1 is closed in cold winter operation, is opened
3 pipeline of heat exchanger, cools down water using surface-type heat exchange, prevents recirculated water from directly contacting with cold air, with anti-cold
But tower freezes, and guarantees safety in production.
The utility model controls first circulation water water inlet pipe 5 and second circulation water water inlet pipe 6 using butterfly valve, weather cold
When by first circulation water water inlet pipe 5 close i.e. close cooling tower water inlet pipe, open 3 pipeline of heat exchanger, changed using surface-type
Heat cools down water, prevents industrial circulating water from directly contacting with cold air, prevents cooling tower from freezing.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
