Abstract
The utility model relates to a cooling tower temperature control device for a workshop cooling pond and solves the problem of energy waste caused by the fact that cooling tower fans of the workshop total cooling pond run continuously. The cooling tower temperature control device comprises the total cooling pond arranged in a workshop, a cooling tower is arranged above the total cooling pond, and the fans are arranged in the cooling tower. The cooling tower temperature control device is characterized in that a main water outlet channel of the total cooling pond is provided with a water temperature sensor, a first fan and a second fan which are started or shut down by water temperature sensor signal control are respectively arranged in the cooling tower, the starting temperature of the first fan is lower than that of the second fan, and the shutdown temperature of the first fan is lower than that of the second fan. The fans of the cooling tower are controlled to run through the outlet water temperature of the total cooling pond, fan running is reasonably planned, and fan energy consumption of the total cooling pond is reduced.
Description
Technical field
The utility model relates to a kind of cooling pond structure, particularly the cooling tower attemperating unit of cooling pond, a kind of workshop.
Background technology
Total cooling pond of machinery production workshop operated by rotary motion, each is all used for cooling from the water intaking of total cooling pond to the technique lathe of cooling water cleannes no requirement (NR), be pooled to after each lathe back pool, by back water pump, sends total cooling pond back to.The cooling water typical temperature of being sent back to by back water pump is higher, causes the water temperature of total cooling pond to raise, and when environment temperature is lower, total cooling pond can reach water temperature requirement by self-radiating; But in environment temperature higher summer, self-radiating cannot reach the cooling demand of cooling water, just need to adopt the blower fan auxiliary heat dissipation of cooling tower, and the water temperature of total cooling pond is controlled at below 30 degree.Traditional blower fan of cooling tower after the higher weather manual unlocking of environment temperature, continuous service, and the water temperature of total cooling pond is dropping to 20 degree when following, the auxiliary heat dissipation effect of blower fan reduces, cooling-down effect is no longer obvious, there is energy waste in the continuous service of blower fan.
Summary of the invention
The purpose of this utility model is to exist for the blower fan of cooling tower continuous service of total cooling pond, workshop the problem of energy waste, and a kind of cooling tower attemperating unit of controlling the cooling pond, workshop of blower fan of cooling tower operation by total cooling pond water temperature is provided.
The utility model solves the technical scheme that its technical problem adopts: the cooling tower attemperating unit of cooling pond, a kind of workshop, comprise the total cooling pond being arranged in workshop, top, total cooling pond is provided with cooling tower, in cooling tower, be provided with blower fan, the main water outlet of total cooling pond is provided with cooling-water temperature sensor, in cooling tower, be respectively equipped with by water temperature sensor signal and control the first blower fan and the second blower fan of opening or stopping, the open temp of the first blower fan is lower than the open temp of the second blower fan, the first blower fan stop temperature lower than the temperature that stops of the second blower fan.By cooling-water temperature sensor, the leaving water temperature of total cooling pond is detected, and water temperature is divided into the fan operation that some ranks are controlled respectively cooling tower.When water temperature is during lower than the open temp of the first blower fan, two blower fans all stop; When water temperature rise to surpass the first blower fan open temp lower than the second blower fan open temp, the first blower fan is opened and the second blower fan stops; When the open temp of water temperature higher than the second blower fan, two blower fans are all opened; After fan operation, water temperature drop to the second blower fan stop temperature time, the second blower fan stops the first blower fan and is held open; When water temperature drops to the temperature that stops of the first blower fan, two blower fans all stop.According to water temperature, just control fan operating numbers, reduce the total energy consumption of cooling tower.
As preferably, the open temp of described the first blower fan is 23 ℃, and the open temp of the second blower fan is 27 ℃; The temperature that stops of the first blower fan is 20 ℃, and the temperature that stops of the second blower fan is 23 ℃.
As preferably, on the main water outlet of described total cooling pond, be also provided with out water pump, after cooling-water temperature sensor is arranged at out water pump on main water outlet.Go out the coolant water temperature of water pump output, representative, be the cooling water water temperature that enters concrete lathe.
As preferably, between described cooling-water temperature sensor and the first blower fan and the second blower fan, be provided with PLC control panel.
The utility model is controlled the fan operation of cooling tower by the leaving water temperature of total cooling pond, the operation of the blower fan of making rational planning for reduces the fan energy consumption of total cooling pond.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model.
In figure: 1, muddy water pond, 2, cooling tower, the 3, first blower fan, the 4, second blower fan, 5, PLC control panel, 6, cooling-water temperature sensor, 7, go out water pump.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the cooling tower attemperating unit of cooling pond, a kind of workshop, as shown in Figure 1.This device comprises muddy water pond 1, and the top in muddy water pond 1 is provided with cooling tower 2, is provided with the first blower fan 3 and the second blower fan 4 in cooling tower 2.One side in muddy water pond 1 is provided with main water outlet, is provided with out successively water pump 7 and cooling-water temperature sensor 6 on main water outlet, and cooling-water temperature sensor 6 connects PLC control panel 5, and PLC control panel is controlled the operation of the first blower fan and the second blower fan according to the temperature signal of cooling-water temperature sensor.The open temp of the first blower fan is 23 ℃, and the open temp of the second blower fan is 27 ℃; The temperature that stops of the first blower fan is 20 ℃, and the temperature that stops of the second blower fan is 23 ℃.
By cooling-water temperature sensor, the leaving water temperature of total cooling pond is detected, and water temperature is divided into the fan operation that some ranks are controlled respectively cooling tower.When water temperature is lower than 23 ℃, two blower fans all stop; When water temperature rise to surpass 23 ℃ lower than 27 ℃, the first blower fan is opened and the second blower fan stops; When water temperature is higher than 27 ℃, two blower fans are all opened; After fan operation, water temperature drops to 23 ℃, and the second blower fan stops the first blower fan and is held open; When water temperature drops to 20 ℃, two blower fans all stop; When water temperature rises to more than 23 ℃ again, continue to carry out above-mentioned circulation.
