Abstract
The invention relates to a cooling-tower heat exchanger with evaporated water recovery. The cooling-tower heat exchanger comprises a first group of channels (1) and a second group of channels (2), wherein the first group of channels (1) is used for the passing of external dry and cold airflow, and the second group of channels (2) is used for the passing of damp and hot airflow. The first group of channels (1) is separated from the second group of channels (2), so that water is condensed on a damp and hot airflow wall. Condensed purified water flows into a cooling-tower water pool.
Description
Technical field
A kind of heat exchanger that the application's patent of invention evaporation water general and a kind of wet cooling tower reclaims.Patent of the present invention is general and a kind ofly for wet cooling tower evaporation water, reclaim and the method and apparatus of fog dispersal, reduces water consumption and the water smoke of cooling tower.
Technical background
In industrial processes, can form a large amount of waste heats.Cooling tower reduces the temperature of water by evaporation, be the place that waste heat shifts.By cooling tower, process a certain proportion of process water, water is wherein by systemic circulation and because evaporation reduces.The loss of this water is very large loss for the user of cooling tower device.
Because the state of the water of cooling tower in clean steam left in evaporation, in system, the concentration of water can raise.For the normal operation of system and cooling tower, must add water and supplement the part water losing because of evaporation and blowdown.Meanwhile, in blowdown part water, contain chemical agent, be difficult to process, very easily cause the pollution of environment.
Water causes loss because of evaporation; And evaporation makes again the cooling water concentration degree of circulation increase, for stabilizing water quality, the normal other filter method of dosing and the blowdown method of adopting, wherein blowdown method is because of investment and the low widely application of operating cost, its processing method higher water of a part of concentration of draining, rely on supplementing water to reduce concentration, have blowdown loss, must have new water to supplement.Meanwhile, water smoke can cause near the equipment of cooling tower and road to freeze, and causes ambient light contamination and affects local climate, causes environmental issue.
Summary of the invention
In order to address the above problem, the invention provides a kind of heat exchanger for the recycle-water type cooling tower that disperses fog, be intended to reduce the water consumption of cooling tower and reduce the steam that cooling tower goes out tower.The effect with good water saving and environmental protection.
Use patent of the present invention, will effectively reduce the water evaporation of cooling tower and the blowdown of system.Air-intake device for controlling the tower body side blinds adjusting device of cooling blast, can regulate according to the design condition of concrete task.In condensation process, water vapour and condensation air form condensation by heat exchanger place, form water droplet on heat exchanger, fall in tower.Because patent of the present invention, the water reclaiming at cooling tower systems approaches pure water, better than the water quality initially adding; Can effectively improve the water quality in cooling tower and industrial circulating water.
On the other hand, patent of the present invention can effectively reduce cooling tower misty rain (going out tower steam).When in tower, damp-heat air and tower condensed exterior air enter heat exchanger, heat exchanger in tower, and according to field condition (design condition), calculate the cold air amount entering in tower, and adjusting louver device in addition, thereby make tower outlet reduce the generation of steam.This patent of invention is very effective to fog dispersal, because the damp and hot steam that can produce steam is before cooling tower is discharged into surrounding environment, its overwhelming majority has been eliminated in tower.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The invention provides a kind of cooling tower: contain tower body, be arranged on blinds adjusting device on the packing layer, storage cistern, tower body sidewall at condensation module in tower body, water-locator, tower body middle part, fan transmission system etc.
Operation principle of the present invention: the air feed shutter device on tower body sidewall, this air feed shutter device can be installed to corresponding particular location according to field condition (design condition).Can regulate, according to actual conditions, realize varying load operation.
In addition, the technical characterictic of the present invention aspect fog dispersal: introduce extraneous with respect to the cold dry air in tower by air feed shutter adjusting device, and with tower in the high wet-hot steam heat exchanger device of entering simultaneously, impel high-temperature water steam in tower to form water droplet in heat exchanger condensation, and recycle-water is in tower.
The present invention can several different methods and structure put into practice and completed, in the situation that not departing from the spirit and scope of the present invention, the requirement of having the right is considered to comprise these equivalent structures.By changing the version of cooling tower, with the obvious advantage compared with prior art: 1) to reduce evaporation capacity, can improve water-saving rate; 2) can eliminate or reduce the steam of tower outlet, reduce environmental pollution, be conducive to environmental protection; 3) in the water reclaiming, contain the water droplet of carrying secretly in tower air, thereby make to waft, drip loss late reduction, environmental protection more, further improves recycling of water.

Fig. 1 is the schematic diagram of the cooling tower heat exchanger that reclaims of a kind of evaporation water that the present invention preferably implements;
Fig. 2 is the principle schematic of the cooling tower heat exchanger that reclaims of a kind of evaporation water that the present invention preferably implements;
Fig. 3 is the frame diagram explanation of cooling tower according to one preferred embodiment of the present invention.
Concrete embodiment:
In conjunction with institute's accompanying drawing, patent of the present invention is described further.
Heat exchanger part
With reference to figure, wherein identical label symbol represents identical element.Fig. 1, has expressed heat-exchanging part (3) in Fig. 2.Shown in 3 be to have much to bond together to form to there is the first passage (1) of two different air-flows and the PVC thin slice (11) of second channel (2) formation.In force, two kinds of orthogonal entering in heat exchanger component (3) of air-flow, keep its separation by thin slice (11), do not make its mixing.Have for the first group of passage (1) by extraneous dry and cold air-flow with by the second channel (2) that contains damp and hot air-flow.First group of passage and second group of passage are separated from each other, and water is condensed in and contain on damp and hot air-flow wall.The pure water that condenses flows in pond of cooling tower.
Housing structure part in enforcement
Use the preferred embodiment of patent of the present invention to be explained in Fig. 3.In Fig. 3, thermal source is sprayed on filler uniformly by spray system (5), and the damp and hot air-flow forming thus and part water droplet, because the draft of axial flow blower (8) is flowed upward, are hospitalized part water droplet in the water collection device of flowing through (4).Damp-heat flows to while above locating by heat exchanger (3), the damp and hot air-flow that the extraneous cold dry air that first passage (in Fig. 2 1) enters and second channel (2 in Fig. 2) enter locates to carry out heat exchange at heat exchanger (3), condensation water outlet is dropped in tower, and steam is eliminated substantially.Whole process is all to be regulated to realize according to on-the-spot situation (or design condition) by the blinds air intake adjusting device (7) on tower body sidewall.To realize to greatest extent water saving and to eliminate water smoke.
The heat exchanger of a kind of recycle-water type of patent of the present invention cooling tower, except being applied in the aspect of cooling tower water saving and fog dispersal, can also be applied in seawater cooling tower aspect.The supplementing or pure water reclaimed to an approach as desalinization as seawater column by the pure water of retrieving.
