In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which:
FIG. 1 is a schematic view of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
fig. 3 is an enlarged view of a portion B in fig. 1.
In the figure: the device comprises a tower body 1, an air duct 2, a fan 3, a packing layer 4, a spraying component 5, a water baffle 6, a beam 7, a column 8, a slide rail 9, a slide block 10, an adjusting component 11, a screw rod 11a, a motor 11b, a water collector 12, a ventilation chamber 13 and a fixed seat 14.
Detailed Description
As shown in fig. 1-3, a mechanical draft cooling tower, tower body 1 has, the top intercommunication of tower body 1 has dryer 2, install fan 3 in the dryer 2, be equipped with packing layer 4 in the tower body 1, packing layer 4's top is equipped with spray set 5, packing layer 4's below interval arrangement has a plurality of breakwaters 6, through a plurality of breakwaters 6 of below interval arrangement at packing layer 4, breakwater 6 establishes the top at ventilation chamber 13, the water droplet that falls packing layer 4 is gathered by breakwater 6 drainage, then fall from breakwater 6's bottom, and then form the independent water curtain of a plurality of individual layers in ventilation chamber 13, form the ventiduct between the independent water curtain of individual layer, the vertical extension of ventiduct, the outer dry and cold air of tower body 1 can get into the vertical depths of ventilation chamber 13 by the ventiduct, thereby the hindrance of continuous water curtain to circulation of air has been avoided, the cooling effect of cooling tower has been guaranteed. The below of packing layer 4 is equipped with crossbeam 7 and stand 8, and the top and the bottom of breakwater 6 respectively with crossbeam 7 and stand 8 swing joint, through with breakwater 6 and crossbeam 7 and stand 8 swing joint for the ascending route of air between breakwater 6 can be adjusted, thereby realizes the regulation to the temperature in the tower body 1. Specifically, the inner wall of tower body 1 is fixed with crossbeam 7 and stand 8, all installs slide rail 9 on crossbeam 7 and the stand 8, and sliding connection has slider 10 on the slide rail 9, and the upper and lower both ends of breakwater 6 are articulated with slider 10 respectively, installs adjusting part 11 on the crossbeam 7, and adjusting part 11 includes screw rod 11a and the motor 11b of being connected with screw rod 11a transmission, and install on fixing base 14 at screw rod 11 a's both ends, and slider 10 screw thread on the crossbeam 7 cup joints in screw rod 11a.
