Description
Technical field
The utility model relates to a kind of open cooling tower drain water recycling systems.
Background technique
The draining of Open Industrial cooling tower is usually originated from industrial tap water or river and lake water, in circulating cooling process
In, after dissolved matter is concentrated 3-5 times, heat exchange equipment surface scale corrodes in order to prevent, and cooling water will do it discharge and more renew water.Quilt
The water of discharge toward contact with the dust particles in a large amount of air during spray, while also can in addition to containing certain salinity
A small amount of pollutant in dissolved air.Cooling tower draining is directly immediately discharged to pipe network by most enterprises at present, then Xiang Leng again
But fresh water is added in tower, is unfavorable for enterprise's drop low water usage and blowdown cost.
Utility model content
It is structurally reasonable the purpose of this utility model is to provide a kind of open cooling tower drain water recycling system, it improves
Useless water reuse, reduces discharge of wastewater；Enterprise water use and blowdown cost are reduced simultaneously.
To achieve the above object, the technical solution of the utility model is to design a kind of open cooling tower draining reuse system
System further includes the catch basin being successively connected with the drainpipe, the including cooling tower and the drainpipe connecting with cooling tower
One water pump, multi-bed filter, the first intermediate water pot, the second water pump, BA filter device, high-pressure pump and membrane filter tube；The film mistake
The second intermediate water pot and MVR evaporator is also respectively connected in chimney filter, and the second intermediate water pot is connected with water demineralizer, and the water is soft
Change and be connected with recovery tube between device and the cooling tower, the MVR evaporator and the second intermediate water pot are connected.
It preferably, further include that the solid waste being connected with the MVR evaporator collects filling.
Preferably, the material of the membrane filter tube is RO film.
Preferably, the multi-bed filter is equipped at least three layer filtration net, and the aperture of the filter screen is gradually reduced, and is leaned on
The filter screen aperture of the nearly first intermediate tank body is minimum.
Preferably, the water demineralizer include cylinder and be set to the intracorporal ion exchange resin of cylinder.
The working principle of the utility model are as follows: waste water is discharged into catch basin by drainpipe and stored by cooling tower, then
The suspended solid in water removal is filtered off by multi-bed filter, because the suspended solid in raw water is more, common filter medium holds
It is easily dirty stifled, by using multi-bed filter, suspended solid is successively retained, extends the cleaning frequency to realize, improves filtering effect
The purpose of rate.To allow the water to meet the needs of entering MVR evaporator, the water outlet of multi-bed filter enters BA filter device, BA mistake
Device is filtered for before membrane filter tube, the further suspended solid crossed in drainage to prevent the runner inside blocking RO film.
The water outlet of BA filter device enters membrane filter tube, the salinity in water is concentrated, resulting fresh water is discharged into second
Between water pot be collected, and highly-saline condensed water then enters MVR evaporator and is evaporated, and resulting condensed water is equally discharged into
Two intermediate water pots are collected, and obtained concentrate residue is discharged into solid waste collection filling and is collected.It is collected in second intermediate water pot
Water using water demineralizer carry out sofening treatment, hardness is down to 1mg/l hereinafter, eventually by recovery tube be discharged into cooling tower into
Row recycles.
The utility model has the following beneficial effects: improving useless water reuse, discharge of wastewater is reduced；Enterprise water use is reduced simultaneously
With blowdown cost.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1, a kind of open cooling tower drain water recycling system, connect including cooling tower 1 and with cooling tower 1
Drainpipe 2 further includes the catch basin 3 being successively connected with the drainpipe 2, the first water pump 4, among multi-bed filter 5, first
Water pot 6, the second water pump 7, BA filter device 8, high-pressure pump 9 and membrane filter tube 10；The membrane filter tube 10 is also respectively connected
Two intermediate water pots 11 and MVR evaporator 12, the second intermediate water pot 11 are connected with water demineralizer 13, the water demineralizer 13 and institute
It states and is connected with recovery tube 14 between cooling tower 1, the MVR evaporator 12 is connected with the second intermediate water pot 11.
It further include that the solid waste being connected with above-mentioned MVR evaporator 13 collects filling 15.
The material of above-mentioned membrane filter tube 10 is RO film.
Above-mentioned multi-bed filter 5 is equipped at least three layer filtration net, the aperture of the filter screen and is gradually reduced, and close to described
The filter screen aperture of first intermediate tank body 6 is minimum.
Above-mentioned water demineralizer 13 is including cylinder and is set to the intracorporal ion exchange resin of cylinder.
The working principle of the utility model are as follows: waste water is discharged into catch basin 3 by drainpipe 2 and stored by cooling tower 1, so
The suspended solid in water removal is filtered off by multi-bed filter 5 afterwards, because of more, the common filter medium of the suspended solid in raw water
It is stifled to be easy dirt, by using multi-bed filter 5, suspended solid is successively retained, extends the cleaning frequency to realize, improves filtering
The purpose of efficiency.To allow the water to meet the needs of entering MVR evaporator 12, the water outlet of multi-bed filter 5 enters BA filter device
8, BA filter devices 8 are used for before membrane filter tube 10, and the further suspended solid crossed in drainage prevents the stream inside blocking RO film
Road.
The water outlet of BA filter device 8 enters membrane filter tube 10, the salinity in water is concentrated, resulting fresh water is discharged into second
Intermediate water pot 11 is collected, and highly-saline condensed water then enters MVR evaporator 12 and is evaporated, and resulting condensed water is same
It is discharged into the second intermediate water pot 11 to be collected, obtained concentrate residue is discharged into solid waste collection filling 15 and is collected.Among second
The water collected in water pot 11 carries out sofening treatment using water demineralizer 13, and hardness is down to 1mg/l hereinafter, eventually by recycling
Pipe 14 is discharged into cooling tower 1 and is recycled.
The utility model has the following beneficial effects: improving useless water reuse, discharge of wastewater is reduced；Enterprise water use is reduced simultaneously
With blowdown cost.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
