Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a mechanically ventilated counterflow wet cooling tower group with a rain zone structure. The ambient wind can flow between the windward towers, and can also enter the leeward tower through the windward tower, increase the ventilation volume of the leeward tower, balance the aerodynamic field in the tower, reduce the ventilation resistance in the rain area of ​​the tower group, and solve the problem of existing cooling towers. The problem of low heat transfer efficiency inside the cluster and on the leeward side

Embodiment 1

[0033] In a typical embodiment of the present invention, such as figure 1 As shown, a mechanical ventilation counterflow wet cooling tower group with rain area structure is proposed, including several rows of cooling tower groups, each row of cooling tower groups is provided with a plurality of cooling tower bodies 1, and the cooling tower groups form a mechanical ventilation counterflow wet cooling tower group (hereinafter referred to as the mechanical tower group).

[0034] The cooling tower body 1 is provided with a tower core element inside. The tower core element includes a spray area, a filler and a rain area. The spray area is located on the upper part of the rain area, and the filler is arranged between the spray area and the rain area.

[0035] The cooling tower bodies of the mechanical tower group are arranged adjacently, and the rain areas of adjacent cooling tower bodies are separated by tower walls, and the tower walls between the rain areas of adjacent cooling to...

Embodiment 2

[0050] Such as figure 2 As shown, in the present embodiment, the second tower wall 3 spaced between the cooling tower groups is set as a porous structure, and the second tower wall 3 is arranged horizontally to connect the first tower wall 2 between the rain areas of the mechanical tower group. .

[0051] Specifically, this embodiment is a group of back-to-back mechanical towers. The mechanical towers in the mechanical tower group have single-sided air intake and are arranged in a back-to-back form. There are 4 mechanical towers in each row, arranged in 2 rows, and a total of 8 mechanical towers.

[0052] The transverse wall between the mechanical tower group rain areas is a porous structure, that is, the second tower wall 3 is a porous structure, and the porosity is set according to the operating conditions of the mechanical tower group, local prevailing wind speed, wind direction, and air temperature. The setting interval is Between 0.2 and 1.

[0053] The second tower wa...

Embodiment 3

[0058] Such as image 3 As shown, what is set as the porous structure in the present embodiment is the first tower wall 2 and the second tower wall 3 between the rain areas of the mechanical tower group, wherein the first tower wall 2 is arranged vertically, and the second tower wall 3 is horizontally arranged. It is set to connect the first tower wall 2 between the rain areas of the mechanical tower group through the second tower wall 3 .

[0059] Specifically, this embodiment is a group of back-to-back mechanical towers. The mechanical towers in the mechanical tower group have single-sided air intake and are arranged in a back-to-back form. There are 4 mechanical towers in each row, arranged in 2 rows, and a total of 8 mechanical towers.

[0060] The horizontal wall and vertical wall between the mechanical tower group rain areas are all porous structures, that is, the first tower wall 2 and the second tower wall 3 are porous structures, and the porosity depends on the operat...

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a group of mechanically ventilated counterflow wet cooling towers with a rain zone structure. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As a kind of heat exchange equipment, cooling tower is widely used in electric power, metallurgy, refrigeration and other fields. Its working principle is to transfer the circulating water carrying industrial waste heat to the atmosphere in the tower to realize the cooling of circulating water. [0004] According to the form of ventilation, cooling towers can be divided into natural ventilation cooling towers and mechanical ventilation cooling towers. Due to its small size and flexible working condition adjustment mechanism, mechanical draft cooling towers have received more and more attention. Mechanical...
