Abstract
The invention discloses a greenhouse type cooling tower and relates to cooling equipment for absorbing and utilizing solar energy. The cooling tower comprises a normal steel structure cooling tower steel frame and a light-transmitting sealing plate arranged on the cooling tower steel frame. Under the condition with sunshine, the light passes through the light-transmitting sealing plate to enter the cooling tower, so that large-space greenhouse effects are formed for heating the hot air in the tower, increasing the air temperature in the tower, lowering the density of the air in the tower, increasing air density difference inside and outside the tower, and improving the suction capacity of the cooling tower. For a wet-type cooling tower, the saturated humidity of the hot air is further increased, the capacity of the hot air carrying water vapor is improved, and the cooling performances of the cooling tower are further strengthened when the hot air temperature of the evaporation region is increased through the greenhouse effects.
Description
Technical field
The present invention relates to a kind of circulating water equipment, particularly to the energy-saving gravity-flow ventilation cooling device that solar energy absorbs, belong to the industrial cooling fields such as electric power, metallurgy, chemical industry,
Background technology
Cooling tower is the key equipment of power plant indirect air cooling unit or closed cycle Water type cooling unit, is set up steam turbine vacuum, and by necessary condition that cold junction thermal source is taken away.But the change of weather directly affects the cooling capacity of cooling tower, time as stronger in sunlight, environment temperature rises, cooling tower heat transfer temperature difference reduces, thus causes ventilation to decline, and causes circulating water temperature to rise further, thus cause unit back pressuce to raise, greatly damage the performance driving economy of unit.At summer high temperature weather, ambient air temperature significantly improves, and causes that circulating water temperature is corresponding significantly to be improved, and causes that unit back pressuce is corresponding significantly to be improved further, affects performance driving economy and the stability of unit on the one hand largely, also greatly reduces unit output.For indirect air cooling unit, when back pressure exceeds to a certain degree, likely exceed the highest operation upper limit of unit back pressuce, the safety in operation of crisis unit.
For the situation of cooling tower hot weather degradation, wet type cooling unit often adopts increase circulating pump to exert oneself, increase the way of circulating water flow, but because water circulating pump initial stage type selecting is limited, be difficult to balance well between long-term efficiency and short-term extreme operating condition, thus be difficult to tackle the problem at its root.Indirect air cooling unit affects more obvious by hot weather, more common way adopts spray to wait the way of spike cooling to improve cooling tower cooling effect, greatly wastes the valuable water resource of arid area on the one hand, and increase energy consumption, pollute pipeline, effect is also limited.
Summary of the invention
The object of this invention is to provide a kind of greenhouse type cooling tower, to overcome the negative effect that hot weather produces cooling tower cooling performance, and convert solar energy into the driving force that can effectively utilize, to improve the overall performance of cooling tower.
Technical scheme of the present invention is as follows:
A kind of greenhouse type cooling tower, comprises steel structure cooling tower steelframe and link plate, it is characterized in that: described link plate adopts light transmission sealing plate.
Preferably, described light transmission sealing plate adopts safety glass or lucite; One-way reflecting transmission coating is scribbled inside light transmission sealing plate.
In technique scheme, described light transmission sealing plate is arranged on inside cooling tower steelframe or is arranged on outside cooling tower steelframe.
The present invention compared with prior art, have the following advantages and the technique effect of high-lighting: when there is sunlight, light therethrough cooling tower light transmission sealing plate enters cooling tower inside, form large space greenhouse effects, hot-air in heating tower, thus the temperature difference increasing hot-air and tower external environment air in tower further, reduce the density contrast of tower inner air and outer air, improve the suction capactity of cooling tower, and then improve the cooling performance of cooling tower.Therefore make up to a certain extent because environment temperature raises the negative effect produced cooling tower cooling performance, thus improve the adaptive ability of cooling tower with variation of ambient temperature.For wet cooling tower, the further raising of temperature in tower, not only increases the density contrast of tower inner air and outer air, can also improve the saturated humidity of air in tower, increases hot-air in tower and carries the ability of recirculated water, further improve the cooling capacity of cooling tower.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of greenhouse type cooling tower.
In figure: 1-steel structure cooling tower steelframe; 2-light transmission sealing plate.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated:
Fig. 1 is the structural representation of a kind of greenhouse type cooling tower provided by the invention, and this greenhouse type cooling tower comprises steel structure cooling tower steelframe 1 and light transmission sealing plate 2, namely replaces the link plate of conventional steel construction cooling tower with light transmission sealing plate.Described light transmission sealing plate can adopt the material that safety glass, lucite and other light transmission are good.Preferably, can also be coated with last layer one-way reflecting transmission coating inside light transmission sealing plate, extraneous light can be entered, and internal light is difficult to leave.Light transmission sealing plate can be arranged on inside cooling tower steelframe, also can be arranged on outside cooling tower steelframe.
One of the present invention is specifically implemented as follows: first require and the selected light transmission sealing plate such as material behavior, price material, as safety glass, lucite etc. according to property of cooling tower; Secondly according to local environment as weather conditions design steel structure cooling tower steelframe (generally little than same performance conventional steel construction cooling tower) such as wind speed, temperature, sunshines, design cooling tower steelframe designs the mounting groove of light transmission sealing plate, adopts welding to be connected with bolt the method combined and carry out the installation of cooling tower steelframe; Then select one-way reflecting transmission coating according to factors such as the market prices, light transmission sealing plate is smeared; Finally, after cooling tower steelframe installs, carry out light transmission sealing plate fills.
Operation principle of the present invention is as follows:
When there is sunlight, light therethrough cooling tower light transmission sealing plate enters cooling tower inside, form large space greenhouse effects, hot-air in heating tower, thus increase the temperature difference of hot-air and tower external environment air in tower further, reduce the density contrast of tower inner air and outer air, improve the suction capactity of cooling tower, and then improve the cooling performance of cooling tower.Make up to a certain extent because environment temperature raises the negative effect produced cooling tower cooling performance with this, thus improve the adaptive ability of cooling tower with variation of ambient temperature.For wet cooling tower, the further raising of temperature in tower, increases the density contrast of tower inner air and outer air on the one hand, on the other hand, the saturated humidity of air in tower can also be improved, increase hot-air in tower and carry the ability of recirculated water, further improve the cooling capacity of cooling tower.
