Abstract

The utility model relates to a heat pipe type cooling tower water-saving device which comprises a circulating water pre-cooling device arranged on a water inlet pipeline of a cooling tower, wherein the circulating water pre-cooling device mainly comprises a cooling box with air channels formed in the two sides and a water tank located on the bottom of the cooling box, the water tank and the cooling box are separated through a partition board, the water tank is connected to the water inlet pipeline of the cooling tower in series, a radiating pipe containing working media is arranged on the partition board, the evaporating end of the radiating pipe is inserted into the water tank, and the condensing end of the radiating pipe is inserted into the air channel of the cooling box. The whole device is easy to produce and simple and compact in structure, transformation of an original cooling tower is not needed, and pre-cooling of circulating water and water saving can be achieved simply by enabling the device to be connected to the water inlet pipeline of the cooling tower in series; circulating water is pre-cooled before entering the cooling tower by means of the efficient heat conducting property of a heat pipe, the load of the cooling tower is reduced, and then water loss caused by evaporation during cooling is reduced.

Description

The cooling tower water saving fixtures of a kind of heat pipe-type
Technical field
The utility model relates to a kind of pre-cooled device, is specifically the cooling tower water saving fixtures of a kind of heat pipe-type.
Background technology
Along with deepening continuously of industrialized production, scale and the quantity of all kinds of cooling towers increase gradually, and evaporative cooling tower take that its cost is low, heat exchange efficiency is high, the cooling limit is widely used in all trades and professions as advantages such as air ' s wet bulb temperatures; But water directly contacts with air in evaporative cooling tower, one side relies on water and cross-ventilation heat exchange and cooling, relies on the other hand part evaporation of water process to carry a large amount of gasification latent heats and cooling, and wherein the latter is the main type of cooling; In cooling procedure, evaporation of water loss amount accounts for the 40%-60% of the total water consumption of power plant, and the consumption of this part water resource cannot be retrieved when being huge; In addition, the water losing because of evaporation can form at cooling tower tower top " white cigarette ", and surrounding environment is caused to pollution to a certain degree; The evaporation of water consumption how reducing in cooling tower running becomes a large problem that perplexs cooling tower industry.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of heat pipe-type cooling tower water saving fixtures, and this device can advance reduction water temperature be alleviated the problem of a large amount of water consumptions of cooling tower.
In order to solve above technical problem, the utility model provides a kind of heat pipe-type cooling tower water saving fixtures, comprise the pre-cooled device of the recirculated water being located on cooling tower inlet pipeline, the pre-cooled device of recirculated water mainly comprises that both sides have the heat dissipation tank and the water tank that is positioned at heat dissipation tank bottom in air channel, between water tank and heat dissipation tank, by dividing plate, isolate, water tank is connected on cooling tower inlet pipeline, on dividing plate, be provided with the radiating tube that includes working medium, it is inner that the evaporation ends of radiating tube inserts water tank, and the condensation end of radiating tube inserts in the air channel of heat dissipation tank; This device utilizes the feature of hot tube high-efficiency heat conduction, and the heat of recirculated water is exported in extraneous air, carries out precooling before, thereby reduce the water yield that cooling tower load reduces evaporation loss in cooling procedure thereby make recirculated water enter cooling tower.
The technical scheme that the utility model further limits is:
Further, cooling tower inlet pipeline comprises the first water inlet pipe and the second water inlet pipe, and the first water inlet pipe connects water tank inlet, and the second water inlet pipe is connected between water outlet of water tank and cooling tower water inlet, by pipeline segmentation design, is convenient to later maintenance and repairs.
Further, heat dissipation tank is provided with blower fan near the air channel of the second water inlet pipe one side, and the air channel sidewall of heat dissipation tank is screen pack, and blower fan is for increasing air agitation enhanced heat exchange.
Further, the condensation end of radiating tube is provided with fin, and fin can effectively expand the heat exchange area of air side.
The beneficial effects of the utility model are: whole device is convenient for production, simple and compact for structure, without original cooling tower is transformed, only this device need be connected on cooling tower inlet channel and can realize the object to the pre-cold-peace water saving of recirculated water; Utilize the feature of hot tube high-efficiency heat conduction, make recirculated water enter cooling tower and carry out precooling before, thereby reduce the water yield that cooling tower load reduces evaporation loss in cooling procedure; In device, between hot water and air, rely on the capable heat exchange of the hot swap-in of high efficient heat exchanging element, hot water does not occur directly to contact with air, does not have evaporation of water loss in the cooling procedure of hot water; Utilize blower fan and enhanced fin heat transfer effect, fin can effectively expand the heat exchange area of air side, and blower fan can be strengthened air agitation, further enhanced heat exchange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
embodiment 1
The cooling tower water saving fixtures of heat pipe-type that the present embodiment provides, as shown in Figure 1, cooling tower inlet pipeline comprises the first water inlet pipe 1 and the second water inlet pipe 2, the first water inlet pipe 1 connects the water inlet of water tank 3, the second water inlet pipe 2 is connected between the delivery port of water tank 3 and the water inlet of cooling tower 4, water tank 3 tops are provided with heat dissipation tank 5, between water tank 3 and heat dissipation tank 5, by dividing plate 8, isolate, the air channel sidewall of heat dissipation tank 5 is screen pack 6, heat dissipation tank is provided with blower fan 7 by the air channel of 5 nearly the second water inlet pipe 2 one sides, the air supply direction of blower fan 7 is contrary with the water (flow) direction in water tank 3, on dividing plate 8, be provided with the radiating tube 9 that includes working medium, the evaporation ends of radiating tube 9 inserts water tank 3 inside and does heat exchange with the recirculated water in water tank 3, the condensation end of radiating tube 9 inserts in the air channel of heat dissipation tank 5, the condensation end of radiating tube 9 is provided with fin 10,
During work: first the recirculated water that need to be cooled enter water tank 3 by the first water inlet pipe 1, pass through heat convection, the heat of recirculated water passes to the evaporator section of radiating tube 9, heat absorption evaporation by working medium arrives the cold rear working medium condensation heat release of radiating tube 9 condensation ends chance, heat is passed to air by tube wall and the fin 10 of radiating tube 9 condensation ends by heat convection, condensed working media comes back to the evaporator section of radiating tube 9 under the effect of gravity, so move in circles, in the middle of heat is constantly passed to air from the fluid of below, realize two kinds of Continuous Heat Transfer between fluid.
