Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, the energy-saving counter-flow cooling tower described in this embodiment includes an air duct 1, a tower body 2 and a water pool 3, an induced draft fan 4 is disposed in the air duct 1, an air inlet 5 is disposed on the tower body 2, a water collector layer 6, a spray layer 7, a packing layer 8 and a packing layer support are sequentially disposed in the tower body 2 from top to bottom, the spray layer 7 includes a plurality of water distribution pipes and a plurality of nozzles uniformly distributed on the water distribution pipes, the water distribution pipes are connected to a water inlet pipe 9 of the cooling tower, the packing layer support includes a frame body 10 and a plurality of small section beams 11 disposed on a top surface of the frame body 10, the small section beams 11 are in contact with a bottom surface of the packing layer 8, a cross section of each small section beam 11 is rectangular or C-shaped, the small section beams 11 are made of steel or glass fiber reinforced plastic, and a cross section width of the preferred small section beam 11 is 3cm to 10cm.

Support body 10 includes many stands, has set firmly the connecting rod of X shape between the adjacent stand, and the stand bottom surface can the snap-on 3 bottom surfaces in pond, and another kind of fixed mode of stand is: concrete buttresses 12 are poured in the pool 3, and the bottom surfaces of the upright posts are fixedly arranged on the concrete buttresses 12.

The working principle of the embodiment is as follows:

when the new tower is cast and constructed, a thick beam fat column used for supporting the packing layer 8 in the tower is cancelled, and the packing layer bracket is directly erected for supporting the packing layer 8, so that compared with concrete beam support, the shielding area of a small-section beam 11 in the packing layer bracket on the bottom of the packing layer 8 is obviously reduced, and the air distribution uniformity of the cooling tower is obviously improved; compared with the prior art, the cooling efficiency is higher under the same external environment condition, the water temperature of the discharged tower is closer to the design target, the energy consumption of the fan is lower, the circulating water compensation capacity is lower, and the purposes of energy conservation and environmental protection are favorably realized;

former thick roof beam fat post in the tower need not to get rid of when old tower is reformed transform, only need make 10 top surfaces of support body and little section roof beam 11 exceed original concrete beam who supports packing layer 8 can, have the difference in height between 8 bottom surfaces of packing layer and the concrete beam this moment, the air current still can get into in the packing layer 8 smoothly.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
