Description
Technical Field
The invention relates to the technical field of fog dispersal water-saving cooling towers, in particular to a multi-channel fog dispersal water-saving device and a cooling tower.
Background
Water resources in China are also very unevenly distributed in regions, the difference between the south and the north is large, and the contradiction between the supply and the demand of the water resources is very prominent. At present, the industrial field of China wastes more water resources, and the recycling rate of the water resources is lower. Therefore, the development of a new water-saving technology, the reduction of industrial water consumption and the improvement of the recovery and utilization rate of industrial water resources have great significance.
When a traditional mechanical ventilation cooling tower runs, cold air is in direct contact with circulating water to exchange heat. The saturated humid air formed is directly discharged outside the tower, causing a large loss of cooling water. Meanwhile, the hot and humid air coming out of the tower contacts and mixes with the external cold air, and forms fog after condensation, which affects the humidity and visibility of the surrounding environment and becomes a carrier of the fog and haze, thus causing environmental pollution. Because the air takes away a large amount of vapor, the concentration multiple of circulating water in the tower is increased, the circulating times are reduced, and the sewage discharge amount and the medicament use amount are increased. Therefore, it is very important to recycle the water vapor in the humid air.
The existing defogging type cooling tower still has some problems in use: the traditional finned tube radiator has large wind resistance, high cost, limited space of a cooling tower and small area of a heat exchanger, so that the fog dissipation and water saving effects are not ideal.

As shown in fig. 1, the cold and hot air channels are arranged in different order to form two different fog-dispersal water-saving modules, namely a first fog-dispersal water-saving module 41 and a second fog-dispersal water-saving module 42. The cold hot air channels in the first fog dispersal water saving module 41 are sequentially and alternately arranged in a circulating manner according to the arrangement sequence of the first hot air channel 100, the first cold air channel 300, the second hot air channel 200 and the second cold air channel 400. The cold and hot air channels in the second fog dispersal and water saving module 42 are sequentially and alternately arranged in a circulating manner according to the arrangement sequence of the second cold air channel 400, the second hot air channel 200, the first cold air channel 300 and the first hot air channel 100.
The fog dispersal water saving module 4 is formed by sequentially and alternately distributing a first fog dispersal water saving module 41 and a second fog dispersal water saving module 42.
The lower area of the fog dispersal water saving module 4 is divided into a hot channel 7 and a cold channel 9 which are alternately distributed by a partition plate 8. The damp and hot air in the tower flows into the fog dispersal water saving module 4 through the hot channel 7. The distribution of the hot and humid air at the inlet of the defogging and water saving module 4 is shown as the hot air inlet 46 in fig. 8.
The lower part of the cold channel 9 is provided with a first louver 10. The opening degree of the first louver 10 is adjustable, and the purpose of controlling the flow rate of the cold air is achieved. The first louvers 10 are arranged on the front and rear side outer walls of the tower body 1. The first louver 10 communicates the cold air outside the tower with the cold channel 9 inside the tower. And second shutters 11 are arranged on two sides of the fog dispersal water saving module 4. The opening degree of the second louver 11 is adjustable. The second louvers 11 are disposed on left and right side outer walls of the tower body 1. The second louver 11 communicates the cold air outside the tower with the cold channel 9 inside the tower. The cold air outside the tower enters the fog dispersal water saving module 4 through the first louver 10 and the second louver 11. The distribution of the cold air at the inlet of the fog dispersal water saving module 4 is shown as the cold air inlet 47 in fig. 8.
The bottom of the cold channel 9 is provided with a partition plate 5. The opening degree of the partition board 5 is adjustable. When the partition 5 is closed, the hot and cold passages 7 and 9 are separated. When the partition 5 is opened, the hot passage 7 and the cold passage 9 are communicated.
When the device operates in summer, the first louver 10 and the second louver 11 are closed, the partition plate 5 is opened, and the fog dissipation and water saving module 4 does not work.
During winter operation, the first louver 10 and the second louver 11 are opened, the partition plate 5 is closed, and the fog dispersal water saving module 4 starts to work. The damp and hot air in the tower enters the fog dispersal water saving module 4 through the hot channel 7 for heat exchange and condensation. The cold air outside the tower enters the cold channel 9 inside the tower through the first louver 10 and the second louver 11, and then enters the fog dispersal water saving module 4. After the cold and hot air exchanges heat in the fog dispersal water saving module 4, the hot air leaves the fog dispersal water saving module 4 from the hot air outlet 43, and the cold air leaves the fog dispersal water saving module 4 from the cold air outlet 44. At the outlet of the fog dispersal water saving module 4, two adjacent outlet channels of the same fog dispersal water saving module (the first fog dispersal water saving module 41 or the second fog dispersal water saving module 42) respectively blow out cold air and hot air, so that the mixing effect of longitudinal cold air and longitudinal hot air can be enhanced. The channels of two adjacent fog dispersal water saving modules (the first fog dispersal water saving module 41 and the second fog dispersal water saving module 42) are opposite to each other to respectively blow out cold air and hot air, so that the mixing effect of transverse cold air and transverse hot air is enhanced, and the fog dispersal effect is enhanced. The arrows in fig. 1 to 6 show the flow paths of the hot air and the cold air in the fog dispersal water saving module 4, wherein the solid lines represent the flow paths of the hot air and the dotted lines represent the flow paths of the cold air. It can be seen that the hot and cold air mixing of the present invention is significantly improved.
Fig. 9 and 10 are sectional temperature distribution cloud charts of the space above the outlet of the fog dispersal water saving module and the traditional diamond fog dispersal water saving module at different heights respectively. It can be seen that the temperature distribution of the invention is more uniform at the section with the same height, which shows that the mixing effect of cold and hot air is better and the mixing of cold and hot air is obviously improved.
The above examples are only intended to illustrate the technical solutions of the present disclosure, not to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present disclosure.
