Description
The technical field is as follows:
the utility model relates to an automatic adjustment formula cooling tower rimq device for power plant.
Background art:
in each domestic thermal power plant, all be equipped with industrial circulating water system, carry out circulating water cooling with the form of cooling tower mostly, and in winter severe cold and cold areas such as northeast of China, northwest, the severe phenomenon that freezes and ice deposition often appears in winter in cooling tower, causes filler and beam column crash and falls in the tower, forms the window passageway to reduce the cooling effect of cooling tower, also can increase the maintenance volume, the maintenance cost of cooling tower simultaneously, threaten the safe operation of main system equipment even seriously. Therefore, the invention discloses an automatic adjusting type cooling tower wind shielding device for a power plant, which is an effective method for solving the problem.
At present, the anti-freezing measure commonly adopted by cooling water towers of domestic power plants in winter is to hang wind shields, and the wind shields are not detached after being hung in winter until the weather in spring is warmed up. Firstly, the construction risk exists when the wind shield is suspended, and the constructors are easy to cause personal injury or falling risk; secondly, the wind shield is easy to fall off after being suspended, and icing can be formed at the position when the wind shield is not timely found, so that filler in the tower is easy to fall off to block ventilation, and the ice-breaking work increases the manual maintenance cost; and thirdly, the temperature of the circulating water rises sharply when the temperature rises in the daytime, the temperature of the circulating water periodically warms up and the load rises, and the artificial suspension cannot be quickly adjusted along with the temperature change around the clock, so that the temperature of the circulating water rises, the vacuum of a condenser is insufficient, the vacuum of a unit cannot keep a designed value, the efficiency of a steam turbine is greatly reduced, and the coal consumption is seriously increased.
The invention content is as follows:
the utility model aims at providing a power plant is with automatically regulated formula cooling tower rimq device solves cooling tower circulating water temperature in winter and stabilizes at best design temperature range, can improve steam turbine efficiency, solves the big, the big scheduling problem of capital investment of cooling tower maintenance volume.
The above purpose is realized by the following technical scheme:
the utility model provides a power plant is with automatically regulated formula cooling tower rimq device, its constitution includes: cooling tower, portal support steelframe and windshield driving motor, cooling tower down along air intake installation round group the portal support steelframe, a set of the portal support steelframe be 16, and be cyclic annular arrangement and be in cooling tower's water tower lower extreme, every the portal support steelframe on install one windshield driving motor, windshield driving motor be connected with the windshield, the portal support steelframe the tip with cooling tower's packing layer water tower department connect, the bottom and the support column of packing layer be connected.
The automatic adjustment type cooling tower wind shielding device for the power plant is characterized in that the wind shielding device for the power plant is a group, a wind shielding curtain driving motor is respectively connected with a manual control cabinet and an automatic control system, and the automatic control system is respectively connected with a circulating water temperature sensor and an environment temperature sensor.
The utility model has the advantages that:
1. the utility model discloses a keep circulating water temperature invariable around, through opening and stopping the air blocking curtain driving motor, control air blocking curtain aperture, and then control the intake (like figure 3). The design is divided into automatic control and manual control, the manual control is carried out the manual operation of opening and close the motor by the manual control cabinet, and automatic control is through gathering ambient temperature and circulating water temperature, is carried out logical judgement by control system, and automatic control driving motor opens and close.
The utility model discloses a steel construction is along air intake installation round portal frame under the cooling tower, 16 frames of installation altogether (like fig. 2), and 16 driving motor of installation are installed altogether to 16 driving motor of every frame mounting to installation PVC industry base cloth utilizes driving motor to carry out control switch as the windshield material. The system monitors the temperature of the inlet water of the circulating water condenser in real time, when the temperature of the water drops, the wind-shield curtain is properly closed, the area of the air inlet is reduced, and when the temperature of the water rises, the wind-shield curtain is properly opened, the area of the air inlet is increased, so that the air inlet amount is automatically adjusted, the cooling effect of the cooling tower is achieved, meanwhile, the temperature of the circulating water is controlled to be stable at a set temperature, the efficiency of the steam turbine is improved, and the generator set. In addition, in windy weather, the windward side wind screen can be properly closed, and the problem of uneven air intake of the windward side and the leeward side of the cooling tower is solved.
The utility model discloses also can electric regulation, avoid artifical picking and hanging the risk. The operating and maintaining cost of the cooling tower is greatly reduced, the baffle adopts PVC industrial base cloth, the service life is long, the low temperature resistance and the repeated bending performance are good, and even if cracks are damaged, only simple pasting and repairing can be carried out. Meanwhile, the opening of the wind shield can be adjusted in time according to the environment temperature condition due to convenient and quick adjustment, so that the freezing in the tower is controlled to the maximum extent, the filler of the cooling tower is prevented from being damaged, and the replacement cost of equipment is increased.
The utility model discloses can realize on the spot and remote control in control, can access to power plant main control system, realize carrying out automatic control to cooling tower air inlet area according to circulating water temperature, and then reach the purpose of winter protection and control circulating water temperature in optimum temperature range. When the water temperature is reduced, the baffle is properly closed, the area of the air inlet is reduced, and when the water temperature is increased, the baffle is properly opened, the area of the air inlet is increased, so that the air inlet amount is automatically adjusted, the temperature of the circulating water is controlled to be stable at a set temperature, the efficiency of the steam turbine is improved, and the steam turbine unit is kept in the optimal working condition to run economically.
The utility model discloses can replace traditional artifical installation deep bead, can use manpower sparingly and the maintenance volume, also can avoid taking place personnel and fall the accident. The wind shield can adapt to weather change and power generation load adjustment, automatically adjust the opening of the wind shield according to actual conditions, and adapt to power generation requirements. Simultaneously, according to temperature variation regulation baffle aperture round clock, and then control circulating water temperature, make the condenser vacuum keep outstanding value, improve steam turbine efficiency, the energy saving consumes, promotes generating set economic nature.
