Embodiment 1

[0021] refer to Figure 1-Figure 2 , a water-saving and fog-eliminating cross-flow cooling tower described in this embodiment includes a cooling tower body 1 having an air mixing chamber 10, and the left and right end faces of the cooling tower body 1 are respectively provided with air mixing chambers 10 communicated with The left air inlet 11 and the right air inlet 12; the upper end surface of the cooling tower body 1 is provided with an air duct 2 communicating with the air mixing chamber 10, and the air outlet of the air duct 2 is installed with a A fan for air circulation in the cavity 10; the left air inlet 11 is provided with a first packing device, and the right air inlet 12 is provided with a second packing device; the cooling tower body 1 is located in the first packing device and A water distribution system 3 is provided directly above the second packing device;

[0022] Both the first packing device and the second packing device include a number of packing modules...

Embodiment 2

[0029] The characteristics of this embodiment are: counting from front to back along the longitudinal direction, louver-type shielding structures are installed at the water inlets of the even-numbered packing frames, and the water inlets are in an open state by controlling the opening or closing of the louver-type shielding structures or closed state. Others are the same as in Example 1.

Embodiment 3

[0031] The feature of this embodiment is that: the air mixing chamber of the cooling tower body is also provided with a water collecting pan below the water eliminator. Others are the same as in Example 1.

Abstract

The invention discloses a water-saving and fog-clearing crossflow type cooling tower which comprises a cooling tower body, wherein a left air inlet and a right air inlet are formed in the cooling tower body; an air duct is arranged on the upper end face of the cooling tower body; a first filler device is arranged at the left air inlet; a second filler device is arranged at the right air inlet; a water distribution system is arranged in the cooling tower body; the first filler device and / or the second filler device comprise a plurality of independent filler modules; each filler module consists of a filler frame and filler in the filler frame; a first air inlet is formed in one side of each filler frame, and a first air outlet is formed in the other opposite side; a water inlet is formed in the top face of each filler frame; louver type shading structures are mounted at the water inlets of the odd or even numbered filler frames longitudinally in sequence from front to back; opening or closing of the louver type shading structures is controlled to make the water inlets open or close. The water-saving and fog-clearing crossflow type cooling tower can achieve a fog clearing structure, and has the characteristic of good water-saving effect.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a water-saving and fog-eliminating cross-flow cooling tower. Background technique [0002] In the projects of established power plants, petrochemical, papermaking, metallurgy and other industries, most circulating cooling water systems adopt open systems, and the main equipment is traditional wet cooling towers. The make-up water of this type of circulating cooling water system accounts for more than 60% of the fresh water consumption of the whole plant. For a large iron and steel company such as Shougang, or a large chemical enterprise such as a 4 billion m3 / a coal-to-natural gas project, the size of the circulating water cooling tower is about 200,000 m 3 / h, its replenishment amount is about 2%. During the normal operation of the project, the cooling tower emits about 150,000 tons of water vapor into the air every 2 days, forming fog. [0003] In a traditional cross-flow cooling tower, th...
