Vibrating device, is fixed on screen pack, for screen pack is carried out to vibrational excitation.
Can filter the air entering by air-intake device is set, the screen pack of air-intake device can be existing various forms, specifically can select according to the environment in place.In the space that overhead gage, lower baffle plate, screen pack and tower body surround, do not have water droplet etc. and flow through, ensured the working environment of vibrating device.When after cooling tower work a period of time, screen pack has more sand and dust, can affect the operating efficiency of cooling tower, by vibrating device, screen pack is carried out to vibrational excitation, and the sand and dust that make to be attached on screen pack depart from, and arrive the object of Automatic clearance screen pack.
Described vibrating device can be the existing equipment that can produce vibration or concussion excitation, as vibrating motor etc.
As preferably, the lower end of described screen pack is less than the distance of screen pack upper end apart from tower body outer wall apart from the distance of tower body outer wall.
Arrange like this and can make the vibration of most of sand and dust by vibrating device depart from screen pack, fall to cooling tower outside, the amount that farthest reduces sand and dust and enter air-intake device.
In order there to be higher cleaning efficiency, as preferably, described vibrating device is multiple, is uniformly distributed along the axis of tower body.
More preferred, described vibrating device is 4.
As preferably, on described lower baffle plate, be also vertically provided with annular dust board.
Setting by dust board can entry deterrence air-intake device sand and dust enter tower body inside, ensured the working environment of tower body inside.
More preferred, the top of described dust board is provided with the flange towards screen pack.
The beneficial effects of the utility model are: the week that filler is arranged on heat exchange coil along and top, heat exchanger semi-surrounding is got up, make in shower the spray effect of shower water better, cross section wind speed is more even, effectively improve the heat transfer effect of heat exchanger, can reduce the area of heat exchange coil, reduce manufacturing cost; By screen pack being set to air intake filtration, ensureing has good working environment in tower body; By vibrating device, screen pack is carried out to vibrational excitation, the sand and dust that make to be attached on screen pack depart from, and arrive the object of Automatic clearance screen pack; The lower end of screen pack is less than the distance of screen pack upper end apart from tower body outer wall apart from the distance of tower body outer wall, arranges like this and can make the vibration of most of sand and dust by vibrating device depart from screen pack, falls to cooling tower outside, the amount that farthest reduces sand and dust and enter cooling tower; By dust board is set, sand and dust that can entry deterrence air-intake device enter tower body inside, ensure the working environment of tower body inside.
