Oxygen circulating water energy conserving system of the present utility model can reach following beneficial effect: the circulating water energy conserving system in the utility model comprises by sensing group, first temperature sensor, signal picker, controller, the looped system of motor composition, each parameter situation is monitored therefore, it is possible to instant, and by each signal feedback to controller, realize the effect of automatic control flow, and can saving water resource effectively, realize continuous print water rate control, be conducive to the operational efficiency improving oxygen generating plant unit, ensure safety in production, the energy consumption of water circulating pump can be reduced.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, simple introduction is done below by the accompanying drawing used required in embodiment or description of the prior art, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Accompanying drawing 1 is the schematic diagram of the utility model embodiment.
In accompanying drawing, 1 is water storage device, and 2 is supply lines, and 21 is water circulating pumps, and 22 is pressure sensors, 23 is flow sensors, and 24 is second temperature sensors, and 3 is cooling towers, and 4 is water return pipelines, and 41 is first temperature sensors, 5 is signal pickers, and 6 is controllers, and 7 is frequency converters, and 8 is motors.
Detailed description of the invention
Below by specific embodiment, the utility model is further described.
By reference to the accompanying drawings shown in 1, a kind of oxygen circulating cooling water energy-saving system that the utility model provides, comprises water storage device 1, supply line 2, water circulating pump 21, cooling tower 3, water return pipeline 4.The top of water storage device 1 is connected with cooling tower 3 by water return pipeline 2, and the bottom of water storage device is connected with water circulating pump by supply line 2, and water circulating pump outlet is connected with cooling tower 3 by supply line 2.
Oxygen circulating cooling water energy-saving system also comprises sensor group, and sensor is assembled on supply line 2.Wherein sensor group comprises the second temperature sensor 22, flow sensor 23, pressure sensor 24.Oxygen circulating cooling water energy-saving system also comprises the first temperature sensor 41, first temperature sensor 41 and is arranged on water return pipeline 4.Oxygen circulating cooling water energy-saving system also comprises signal picker 5 and controller 6, and signal picker 5 is connected with controller 6 by RS485.
Oxygen circulating cooling water energy-saving system also comprises frequency converter 7 and motor 8, and frequency converter 7 is connected with motor 8 by cable.
During work, first gathered the transducing signal of the first temperature sensor 41, second temperature sensor 22, flow sensor 23, pressure sensor 24 by signal picker 5, then multiple transducing signal is sent on controller 6.Controller 6 exports the discernible signal of frequency converter after computing, corresponding frequency is provided by adjusting frequency to the motor 8 on water circulating pump 21 after frequency converter 7 receives signal, the rotating speed regulating motor can be realized, thus reach the object regulating the circulation water yield, reduce energy consumption of electrical machinery simultaneously, improve water pump efficiency.Such as when the first temperature sensor 41 temperature is too high, the temperature difference can be caused to rise, controller is to frequency converter positive energize signal, frequency converter just can improve frequency makes motor speed increase, motor speed increases water circulating pump flow and increases, return water temperature then can be made to reduce, thus realize feedback regulation, vice versa.
The utility model provides a kind of oxygen circulating cooling water energy-saving system, can realize continuous print, high-precision water rate control, is conducive to the operational efficiency improving oxygen generating plant unit, ensures safety in production, and can reduce the loss of circulating cooling evaporated quantity of water.Avoid the adverse effect brought because of seasonal variations.
