Further, the online suspension detector, ozone water treatment system are successively set on the heat-exchange apparatus
On pipeline between cooling tower.
Setting control journey in a kind of processing method of above-mentioned Water Treatment in Circulating Cooling System, the intelligence control system
Sequence, when the concentration of suspension that online suspension monitor feeds back reaches the first setting value, the other filter system is opened, when online
When the concentration of suspension of suspension monitor feedback reaches the second setting value, the emergency drainage mechanism is opened.
Further, when the concentration of suspension that online suspension monitor feeds back reaches the first setting value and continues to lift up
When, the opening degree of the other filter system is stepped up, conversely, then progressively declining until closing.
Further, when the concentration of suspension that online suspension monitor feeds back reaches the second setting value and continues to lift up
When, the opening degree of the emergency drainage mechanism is stepped up, conversely, then progressively declining until closing.
The beneficial effects of the present invention are：
1) precipitate for solving to bring because improving cycles of concentration during ozonization cycle cooling water is accumulated, so as to cause
The problems such as blocking that some key position accumulations are brought.
2) by the on-line monitoring of suspension, the discharge capacity of cooling water is farthest reduced, water source is saved, reduction is dirty
Dye.
3) the continuous work of the recirculating cooling water system handled using ozone can be realized, farthest reduces what is shut down
Number of times, improves production efficiency.
4) design of other filter system and emergency dewatering system is ingenious, and other filter or drainage sunk well are realized according to first Monitoring Data
Degree is automatically controlled, strong adaptability, high degree of automation.
5) establish and the automatic monitoring means of complete set and automatically process measure, it is ensured that recirculating cooling water system it is normal
Operation.
Brief description of the drawings
Fig. 1 is Water Treatment in Circulating Cooling System schematic diagram of the present invention.Heat exchanger in figure is provided in heat-exchange apparatus
On heat exchanger.
Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Comparative example：
Certain chemical plant circulation, quantity of circulating water 2000m3/h.Again system is cleaned before going into operation the beginning of this year and
Check, discharge a large amount of iron rust, system internal corrosion is more serious；Cycles of concentration is 2 or so, waste water resource；Air compressor machine form is passed through
Norm is pasted, and it is more that system biological sticks mud；Heat transmission equipment efficiency is reduced, and system has scale formation.In view of the above problems, using smelly
After oxygen processing, upgrading is carried out to existing circular water treating system, takes 3%~5% water of recirculated water to be handled as bypass,
By mixing wastewater with air equipment, ozone gas and side stream are fully dissolved and are mixed into Ozone Water, circulating water treatment system is re-introduced into
System, while sterilizing and algae-removing, reaches anti-corrosion and the balance of scale inhibition, cycles of concentration reaches 6, water saving 60%.After cycles of concentration is improved,
It is found that in white suspension thing, water that concentration of suspension is raised in basin bottom and transparent flowmeter pipeline, it is right as assembled
There is certain risk in pipeline obstruction.
Embodiment one：
For risk present in comparative example, the present embodiment carries out following conceptual design：
Referring to Fig. 1, a kind of Water Treatment in Circulating Cooling System, including intelligence control system, ozone water treatment system；Circulation is cold
But water system includes heat-exchange apparatus, cooling tower, circulating water power mechanism, and three forms the circulation of cooling water；On circulation line
Emergency drainage mechanism is provided with provided with other filter system, cooling tower；The ozone water treatment system is arranged on circulation line, to described
Ozone is added in recirculating cooling water system；The intelligence control system includes control unit, online suspension monitor, for controlling
The electric control valve of emergency drainage processed, described control unit is electrically connected with the online suspension monitor, electric control valve respectively.
Referring to Fig. 1, the cooling tower bottom has tower sink, and the emergency drainage mechanism is connected with tower sink.
Referring to Fig. 1, between the pipeline and recirculated water pump group and heat-exchange apparatus between heat-exchange apparatus and cooling tower
Pipeline respectively filters system connectivity with the side, and the other filter system is connected with the tower sink.
Referring to Fig. 1, after heat-exchange apparatus, water temperature highest pipeline section, there is provided online suspension measuring instrument, water intaking
5% has carried out other filter processing (water pump uses frequency conversion, and treating capacity can change in 0%-5%), passes through online suspension instrument monitoring
Result, carry out the change that other filter system handles flow.When side filter is using full load operation, suspension still former residence is high not in water
When lower, start emergency drainage, specific processing method is as follows：
During with ozone technology processing cycle cooling water, with the raising of cycles of concentration, there are salinity or supersaturated metallics
Separate out, these materials are in suspended state.Can automatic monitor for continuously water using suspension (suspended sol ids) in-line analyzer
Middle suspension, judge suspension in ozone treating process whether close to limit value such as：100mg/L (each system limit value is different, by
Lab scale is determined).If close to (such as：Up to 80mg/L), then other filter is started by automatic control system；If closer to (such as：90mg/L), then
Draining is started by automatic control system, suspension is filtered out or discharged recirculating cooling water system.When suspension drops to above-mentioned set
Below definite value, that is, it is automatically stopped draining or other filter.
The key of the present embodiment is when being handled using ozone cooperative technology recirculated cooling water, online using suspension
Suspension in monitoring analyzer, automatic monitor for continuously water, other filter and draining are automatically controlled according to its data result.
The present embodiment successful implementation, it is ensured that the recirculating cooling water system of ozone processing is not influenceed by precipitate, is being reduced
While circulation blowdown flow rate and amount of makeup water, the safe operation of system has been ensured.
Above is the preferred embodiment of the present invention, one of ordinary skill in the art can also be carried out respectively on this basis
Conversion or improvement are planted, on the premise of the total design of the present invention is not departed from, these conversion or improvement should all belong to the present invention and want
Within the scope of asking protection.
