In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cooling stack air duct with anti-freezing structure, comprise herringbone column, air duct frame structure and glass reinforced plastic panel, air duct frame structure and herringbone column are fixed together, in air duct frame structure, glass reinforced plastic panel is installed, described air duct frame structure is interior outer double-layer structure, layered arrangement in vertical direction, glass reinforced plastic panel is arranged on the skin of air duct frame structure, the middle part of described air duct frame structure is provided with multiple air regulator, multiple described air regulator is movably arranged in air duct frame structure, the position of the corresponding air regulator of described glass reinforced plastic panel is movable structure, that is the glass reinforced plastic panel outside air regulator can be opened with air regulator or close.
Preferably, described air regulator annular array is arranged in air duct frame structure.
Preferably, the top of air duct frame structure is provided with lightning arrester.
Preferably, the material of air duct frame structure is stainless steel.
The beneficial effect that the utility model compared with prior art has is:
1, described air duct frame structure is interior outer double-layer structure, layered arrangement in vertical direction, glass reinforced plastic panel is arranged on the skin of air duct frame structure, so whole parts of the present utility model are all produce at factory floor, Assembling, do not need large-scale construction equipment, construction site is also smaller, and having 1/10th of cement tower construction site can with construction and installation.Greatly can shorten construction period, compared with constructing with cement tower, construction period can the reduction of erection time more than 60% simultaneously.In work progress, do not have dust and noise pollution, construction environment-protecting clean simultaneously.
2, the utility model is compared with the air duct of reinforced concrete structure, and cost can reduce by 20% ~ 50%, and for user and country save a large amount of investments, and the weight of entirety reduces.
3, the top of air duct frame structure is provided with lightning arrester, protects the safety of inner water spray system, ensure that the safe dirt of equipment produces.
4, the utility model arranges adjustable air regulator for ventilating along air duct frame structure outer surface, environmentally temperature air regulator can be opened when using in the winter time, extraneous cold air is not directly entered in tower by the bottom of air duct frame structure, mix with the hot-air in tower, the temperature of hot-air is reduced, the draft of cooling tower reduces, and prevent tube bank Yin Wendu low and freeze, these antifreezing measures cannot realize in traditional cement tower.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure, 1 be herringbone column, 2 be air duct frame structure, 3 be glass reinforced plastic panel, 4 be lightning arrester, 5 for air regulator.
Detailed description of the invention
As shown in Figure 1, a kind of cooling stack air duct with anti-freezing structure of the utility model, comprise herringbone column 1, air duct frame structure 2 and glass reinforced plastic panel 3, air duct frame structure 2 and herringbone column 1 are fixed together, air duct frame structure 2 is provided with glass reinforced plastic panel 3, described air duct frame structure 2 is interior outer double-layer structure, layered arrangement in vertical direction, glass reinforced plastic panel 3 is arranged on the skin of air duct frame structure 2, the middle part of described air duct frame structure 2 is provided with multiple air regulator 5, multiple described air regulator 5 is movably arranged in air duct frame structure 2, the position of the corresponding air regulator 5 of described glass reinforced plastic panel 3 is movable structure, that is the glass reinforced plastic panel 3 outside air regulator 5 can be opened with air regulator 5 or close.
Described air regulator 5 annular array is arranged in air duct frame structure 2.
The top of air duct frame structure 2 is provided with lightning arrester 4.
The material of air duct frame structure 2 is stainless steel.
The utility model has unique advantage with domestic and international similar technique contrast:
(1) cost is low.This Novel cooling tower cost compared with conventional cement cooling tower can reduce by 20% ~ 50%, and building the lower area of cement tower ground material, cost can save more than 20%, in the area that ground material is somewhat expensive, can reduce investment outlay and reach 40%.
(2) lightweight.What cooling tower adopted is metal framework mosaic glass steel facing structure, metal framework structure reasonable in design has higher bulk strength, and weight reduces greatly, the own wt of this light-duty tower is about 4000 tons, about 85000 tons of the own wt of traditional cement tower, only have 1/20th of conventional cement tower, reduce the requirement of cooling tower basis to geological conditions, thus also reduce the processing cost of geology, can use in the area that geology is poor, require the bearing capacity of basic foundation, under the condition that wet shape cools, be greater than 70KPa; The condition of dry calibration is greater than 120KPa.
