Abstract
The utility model discloses an enclosed type cooling tower. A ventilating device, a sprayer, a coil pipe and a coil pipe water collecting plate are orderly and longitudinally arranged in a frame. Water-spraying filling material is also arranged below the coil pipe and is connected with an air inlet. Spray water of which the heat is absorbed by the coil pipe can be cooled automatically in the water-spraying filling material, so the temperature of the spray water when the spray water flows to the coil pipe is always below temperature when the spray water leaves the coil pipe, which improves the cooling performance. Radiation fins can also be arranged at the air inlet at the lower side of the coil pipe for cooling the spray water. Large and medium-sized enclosed type cooling towers adopting the structure of the utility model can reduce the occupation area of the tower body about 36 % and decrease the integrative cost about 5 to 25%.
Description
The utility model relates to a kind of cooling device, particularly a kind of closed cooling tower.
Existing closed cooling tower generally adopts the spray recirculated cooling water that the working medium in the coil pipe is cooled off, and the cooling performance of coil portions is subjected to certain influence.For making the working medium temperature in the coil pipe drop to predetermined value, can only increase heat exchange area, as the length of lengthening coil pipe.Cause closed cooling tower volume benzene heavy, cost an arm and a leg.In addition,, both increased volume, be difficult to satisfy the requirement of water distribution uniformity again because framework and shower water EGR are separate.
The purpose of this utility model be for provide a kind of cooling performance good, can dwindle heat exchange area, structure is light and handy, and the low closed cooling tower of cost.
Further purpose of the present utility model is for a kind of closed cooling tower of energy water distribution uniformity is provided.
Task of the present utility model is finished like this: the closed cooling tower that is made of ventilation unit, framework, spray equipment, coil pipe, coil pipe water-collecting tray and shower water EGR, ventilation unit, spray equipment, coil pipe and coil pipe water-collecting tray vertically are arranged in the framework successively, also be provided with packing below coil pipe, air inlet links to each other with packing.Behind coil pipe, the shower water through absorbing heat carries out self cooling in packing.The damp-heat air that ventilation unit is will be almost saturated is taken away, replenishes cold dry air in the surrounding environment at air inlet simultaneously, thereby the temperature that the temperature when making shower water to coil pipe is lower than it all the time when leaving coil pipe improves cooling performance.
Task of the present utility model can also be finished like this: the closed cooling tower that is made of ventilation unit, framework, spray equipment, coil pipe, coil pipe water-collecting tray and shower water EGR, ventilation unit, spray equipment, coil pipe and coil pipe water-collecting tray vertically are arranged in the framework successively, the air inlet place that surveys under coil pipe also is provided with fin, and shower water is cooled off.Ventilation unit is taken almost saturated damp-heat air away, simultaneously the cold dry air in the additional surrounding environment of air inlet.
Task of the present utility model can also be finished like this: by the closed cooling tower that ventilation unit, framework, spray equipment, coil pipe, coil pipe water-collecting tray and shower water EGR constitute, ventilation unit, spray equipment, coil pipe and coil pipe water-collecting tray vertically are arranged in the framework successively.Also be set up in parallel the shower water self-cooling set in the framework, comprised packing, filler spray equipment that matches with packing and filler water-collecting tray.The import of filler spray equipment is connected with the outlet of coil pipe water-collecting tray.Enter the filler spray equipment again through the shower water behind the coil pipe, in packing, cool off.Thereby the temperature when making shower water arrive coil pipe is lower than it all the time and leaves temperature.Ventilation unit is discharged to almost saturated damp-heat air outside the tower, replenishes the cold dry air in the surrounding environment again at the air inlet place.
Further task of the present utility model is finished like this: the shower water EGR is arranged in the framework, constitutes one with framework.Shower water directly enters spray equipment via each column of framework, forms a plurality of water inlets, but water distribution uniformity.
Because the utility model is provided with packing or fin below coil pipe, the part heat of shower water through being taken out of behind the coil pipe, can cool off again at packing or fin respectively, guarantee the temperature when temperature when shower water advances coil pipe is lower than it all the time and leaves coil pipe, alleviated amount of cooling water requirement greatly to the coil pipe section, improved cooling performance, thereby can make the length of coil pipe reduce 15～20%;
The shower water EGR is arranged in the framework, and shower water directly enters spray equipment by upright of frame, forms a plurality of water inlets, but both water distribution uniformities can reduce material again, reduce weight;
Be provided with in the framework and isolate the air channel, discharge via isolating the air channel, no longer participate in the caloic exchange of coil pipe section by the air intake of packing inlet;
Be provided with air inlet and orifice plate between coil pipe and the packing, can further improve the cooling performance of coil pipe section;
Volume is little, in light weight, cost is low.
Below, introduce the utility model in conjunction with the accompanying drawings in detail.
The closed cooling tower of Fig. 1 for adopting packing and being connected in series with the coil pipe section
Fig. 2 has the closed cooling tower of isolating the air channel
Fig. 3 is for adopting the closed cooling tower of fin
Fig. 4 is the closed cooling tower that has the recirculated water Aftercooling device
