Two industrial water pumps, are connected with industrial water tank and return water tank respectively by outlet conduit, and during an operation, another is for subsequent use.
Further, described industry water inlet channel, CWR road and three outlet conduits are respectively provided with valve.
Further, described industrial water pump flow is 30m
3/ h, lift is 30m.
Further, described closed cycle water device also comprises two drainage pipelines, and one is connected with the outlet conduit of industrial water tank, and another is connected with the outlet conduit of return water tank, for discharging excess moisture.
Further, two described drainage pipelines are respectively provided with valve.
Further, described industrial water tank and return water tank inside are respectively provided with temperature detecting module.
Further, described industrial water tank and return water tank inside are respectively provided with water level detecting module.
Further, described industrial water tank and return water tank top are respectively provided with a manhole.
Operation principle of the present utility model is:
Industrial water tank is for storing industry water, industry water flows to unit by industrial water pump and cools, the cooled water of unit is recovered water tank by CWR road again and reclaims, the coolant-temperature gage just entered in return water tank is very high, due to return water tank and industrial water tank only have a wall every, and it is very large with the industry water temperature difference in industrial water tank, the two spontaneously can carry out heat exchange, return water temperature is reduced with this, backwater after cooling can as cooling water, flow to unit by industrial water pump again, form a cyclic process.
In running, when temperature detecting module detects that industry water or return water temperature reach warning temperature, industry water inlet channel and industrial water tank outlet conduit valve can be opened automatically, supplement cold water (industry water), make industry water be in recurrent state, make industry water and return water temperature be reduced to normal condition; When the moisture in whole device is inadequate (moisture is not less to when having normal cooling effect), the outlet conduit valve open of industry water inlet channel and industrial water tank, supplements cold water; When industry water and return water temperature is normal and the water yield is sufficient time, the valve of industry water inlet channel is in closed condition, no longer carry out moisturizing, the outlet conduit valve of industrial water tank regulates as required, and the backwater now primarily of return water tank circulates as cooling water.In addition, industrial water tank and return water tank inside are all equipped with water level monitoring module, when the water level in industrial water tank or return water tank exceedes default maximum stage, discharge water by the drainage pipeline being arranged on water side, ensure that water circulation is normally carried out; When industrial water tank water level inside is too low, water level monitoring module can send signal, by opening industry water inlet valve and closedown or turning the valve of industry water outlet conduit down, guarantees that the water level in industrial water tank revert to normal condition.
The beneficial effect that the utility model obtains is:
1. return water tank is arranged on the inside of industrial water tank, four periderm industry waters surround, just enter return water temperature in return water tank higher than the industry water in industrial water tank, the two spontaneously can carry out heat exchange, without the need to lowering the temperature artificially, without the need to setting up heat-exchange apparatus, decreasing energy consumption, reducing the expense of purchase of equipment;
2. is spontaneous cooling down mode due to what adopt, technological process is simple, eliminates some intermediate links, detects, managing and control system is simple, failure rate is low;
3. adopt this return water tank mode nested with inside and outside industrial water tank, return water tank is equivalent to be in a gentle external environment condition, and safety coefficient is high, is applicable to more complicated space enrironment, and structure is simple, inspection, easy to maintenance;
4. return water tank is in industrial water tank inside, eliminates heat-exchange apparatus, takes up room little, and the repowering in short supply for script space is very helpful.
