Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
See Fig. 1-3, a kind of Anti-overflow device of pump tower common manifold interconnection system open cycle cooling water, it is characterized in that, including recovery channel, electromagnetic valve, cooling water storage tank, reflux pipe, ball-cock assembly, time controller, cooling tower enters tower main, cooling tower goes out tower main, communicating pipe, enter tower water pipe electrodynamic valve, wherein, enter tower water pipe electrodynamic valve to be arranged on cooling tower and enter on tower main；Electromagnetic valve is arranged on recovery channel；Cooling tower storage tank is connected with cooling tower by reflux pipe；Being connected by communicating pipe between cooling tower with cooling tower, described cooling tower storage tank is provided with blow-off line, when cooling water storage tank needs are relatively big or installation site is by limited time, and cooling water storage tank can use the form of series connection to be connected by storage tank communicating pipe.
When cooling water enters the electrodynamic valve closedown of tower water pipe, output signal to time controller, time controller output signal, open and the electromagnetic valve entered in the recovery pipe that cooling tower pipeline is connected, part cooling water enters cooling water storage tank, the time that electromagnetic valve is opened is controlled (this time sets) when debugging by the electrodynamic valve entering tower water pipe, corresponding with the model of the cooling tower closed, the electromagnetic valve opening time controls before electrodynamic valve completely closes, and when having multiple electrodynamic valve to simultaneously close off, this time adds up.After completing water storage work, cooling water storage tank is connected by the reflux line tower tray that catchments with cooling tower, and when cooling tower water level drops to set low water level, ball-cock assembly is opened, and cooling water passes through reflux pipe entrance cooling tower, amount of makeup water.When cooling tower water level rises to set high water level, ball-cock assembly is closed, and stops moisturizing.By this process the most repeatedly, the water of cooling water storage tank is finally back in system.
Anti-overflow device equipment and the selection of pipeline
According to " building plumbing system design manual " second edition the 12.5.2 article, the water-locator of cooling tower and the liquid distribution attachment water yield are the 1.5% ~ 2.0% of quantity of circulating water, after cooling water to cooling water storage tank, least favorable situation catchments tower tray to low water level for now cooling tower, the most a part of water is back to water-collecting tray, until after high water level, stopping moisturizing.Therefore the computing formula of dischargeable capacity V of cooling water storage tank is:
V=V1+hA
V1=water-locator and the liquid distribution attachment water yield (m3)
The h=tower tray high-low water level that catchments is poor (m)
A=catchments tray area (m2)
