Abstract
The utility model discloses a joint control system for cooling towers. The joint control system comprises a first fan, a second fan, a third fan, the first cooling tower, the second cooling tower and the third cooling tower. The first fan, the second fan and the third fan are arranged at the upper end of the first cooling tower, the upper end of the second cooling tower and the upper end of the third cooling tower respectively and connected in series. Intelligent optimization control over the cooling towers is adopted for the joint control system, evaporation amount of circulating water of the cooling towers and electric charge cost of the fans of the cooling towers can be effectively reduced, and the comprehensive electricity-saving rate is 20%-50%.
Description
Technical field
The utility model relates to cooling tower energy-conserving and environment-protective field, especially a kind of cooling tower combined control system.
Background technology
At present, industrial cooling tower blower fan turns round always under power frequency state, can not carry out real-time adjust operation frequency according to load and environmental change, and the cooling water leaving water temperature of cooling tower can be because of the variation difference of the size of load and environment temperature, humidity in one day.Particularly environment temperature, the humidity of morning and evening differ greatly, and at this moment the actual leaving water temperature of cooling tower also can respective change.And blower fan of cooling tower is no matter how weather changes, and the load variations of cooling load end how, power frequency full power operation all the time.In the time that system cools coolant-temperature gage approaches wet-bulb temperature, blower fan can not adaptive change, still power frequency running, and the energy consumption that now spent can not reduce temperature again, just produces huge energy consumption waste.Simultaneously in the time of system, the parameter of cooling device is all to produce and the maximum load of ambient parameter is that standard designs, and retains certain surplus simultaneously, but in actual motion, it is few that system operates in the extreme case of maximum load, less than 10% of whole service year.So in nearly 90% time, have a large amount of design power surpluses when the equipment operations such as blower fan, therefrom can obtain the larger energy saving space.Blower fan of cooling tower in the winter time for energy-conservation conventionally can standard-sized sheet, and there is following point in this start-up mode: one, cooling tower has the cooling water return water temperature of blow in machine and the machine that do not blow in different.While dropping in tank under water, form mixed water phenomenon when uneven in temperature, promoted the temperature of cooling backwater, affected cooling effect; When two, 2 Fans are only opened 1, the blower fan mouth of start can not form a huge wind-tunnel, causes air flow shortcircuit, affects air intake and the cooling effect of another cooling tower; When three, 2 Fans are only opened 1, area of dissipation is underutilized, and cooling capacity is not fully exerted.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of cooling tower combined control system.
For realizing this technical purpose, scheme of the present utility model is: a kind of cooling tower combined control system, comprises the first blower fan, the second blower fan, the 3rd blower fan, the first cooling tower, the second cooling tower and the 3rd cooling tower; Described the first blower fan, the second blower fan and the 3rd blower fan are arranged at respectively the first cooling tower, the second cooling tower and the 3rd cooling tower upper end; Described the first blower fan, the second blower fan and the 3rd fans in series are connected.
Compared with prior art, the beneficial effects of the utility model are: this cooling tower combined control system, adopt the control of cooling tower intelligent optimization, and can effectively reduce the evaporation capacity of cooling-tower circulating water and the grid electricity fee cost of blower fan of cooling tower; Integrated power-saving rate 20%-50%.
Brief description of the drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is that the utility model blower fan of cooling tower power percentage and air quantity percentage are with power frequency change curve;
Wherein: 1, the first blower fan, 2, the second blower fan, 3, the 3rd blower fan, 4, the first cooling tower, 5, the second cooling tower, 6, the 3rd cooling tower.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1～2, in the utility model embodiment, a kind of cooling tower combined control system, comprises the first blower fan 1, the second blower fan 2, the 3rd blower fan 3, the first cooling tower 4, the second cooling tower 5 and the 3rd cooling tower 6; Described the first blower fan 1, the second blower fan 2 and the 3rd blower fan 3 are arranged at respectively the first cooling tower 4, the second cooling tower 5 and the 3rd cooling tower 6 upper ends; Described the first blower fan 1, the second blower fan 2 and the 3rd blower fan 3 are connected in series.
The utility model operation principle is: open whole many Fans simultaneously, adopt associating converter technique, make many Fans operate in identical frequency, when blower fan is at 25HZ-42HZ section operation, now only consume the electric weight of 13%-51%, but air quantity can reach 55%-86%.Under the prerequisite that meets cooling requirement, make as far as possible fan operation in efficient district, to reach the object that improves efficiency.Simultaneously, cooling tower efficiency switch board can be realized cooling tower fan start operation automatically, automatically the operational efficiency of computing environment temperature, humidity, Inlet and outlet water variations in temperature, cooling tower etc. in running, and the optimal operating condition of Automatic-searching cooling tower, realize fully automatic operation.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any Reference numeral in claim should be considered as limiting related claim.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle amendment that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
