Description
Technical field
The utility model relates to the cooling device in power industry, particularly a kind of heat exchanger with volume adjusting apparatus be applied in cooling tower.
Background technology
Cooling tower is cooling device conventional in the industry such as electric power, oil, chemical industry, pharmacy, oil refining.In known technology, cooling tower adopts gravity-flow ventilation, hyperbola, reinforced concrete structure.Indirect air cooling mode, as the conventional methods for cooling of cooling tower, obtains fast development in China in recent years.The heat exchanger of indirect air cooling system, usually have two kinds of arrangements, one is arranged horizontally in air cooling tower, another kind of for being arranged vertically on the peripheral circumferential space of air cooling tower.
Severe cold period, especially northern area in the winter time, easily there is the freezing accident of heat exchanger in indirect air cooling system unit, water circulation can be caused to interrupt, heat exchanger bursting by freezing time serious, and even indirect air cooling system is stopped transport.Cause the main cause freezed to be that the water temperature entered in heat exchanger is low, heat is few, and the quantity delivered of sub-zero cold air too " is had more than needed ".Existing antifreezing measures are that the air intake surface of heat exchanger is provided with motor-driven shutter, control the air capacity by heat exchanger by change shutter aperture.Shutter is different according to weather, and select to open or close, as when summer temperature is higher, shutter will be opened completely, to reach maximum radiating effect; When temperature is lower in the winter time, shutter will partially or completely be closed, and freeze heat exchanger to prevent cool ambient air.But during non-antifreeze operating mode, because shutter needs to use a large amount of curtain sheet, when shutter is opened completely, curtain sheet is shield portions incoming air area still, and this causes the air intake resistance of cooling tower to increase, reduce intake, reducing cooling effectiveness, for reaching same cooling effect, using the cooling tower of shutter than the cooling tower not using shutter, size is larger, which increases equipment cost and engineering cost.
Summary of the invention
For realizing preventing freeze in winter, the air intake surface simultaneously overcoming existing heat exchanger uses shutter to cause cooling effectiveness to reduce, the utility model provides a kind of heat exchanger with volume adjusting apparatus, it arranges volume adjusting apparatus at air intake surface, the volume adjusting apparatus of this heat exchanger takes up room little, can cooling effectiveness be improved, reduce cooling tower size.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of heat exchanger with volume adjusting apparatus, its two sides are made up of the radiating fin managed and be arranged on pipe, and bottom surface is air intake surface, and air intake surface arranges volume adjusting apparatus.Outside air by volume adjusting apparatus, to contact with radiating fin with the pipe in heat exchanger and completes heat exchange.Heat exchanger is horizontally disposed or be arranged vertically.Volume adjusting apparatus can be rolling screen door, vertical hinged door, hinged door, sliding door or structure of folding door, preferred folding door and rolling-door structure.Volume adjusting apparatus has automatic control system and manual control system, and can control the open and close of volume adjusting apparatus by automatic or manual, automatic or manual regulates opening degree.Volume adjusting apparatus comprises a body and motor, and door body is made up of single or multiple door sheet.Volume adjusting apparatus has some fixing points, can when different opening degrees, fixing volume adjusting apparatus.Further, the volume adjusting apparatus of rolling-door structure, comprises guide rail, roller shutter box, spool.
This heat exchanger applications is in cooling tower.Be provided with support column bottom cooling tower, be also furnished with multi-group heat exchanger.
The beneficial effects of the utility model are owing to adopting the volume adjusting apparatus improved, do not freezing dangerous season, volume adjusting apparatus standard-sized sheet, the curtain sheet overcoming shutter takies the defect of part incoming air area, have when freezing danger, according to actual Air Quantity Required opening section volume adjusting apparatus, while preventing freezed in winter, improve cooling effectiveness, reduce equipment cost and engineering cost.

Fig. 2 is the schematic diagram of the horizontally disposed heat exchanger with volume adjusting apparatus.
1. cooling towers, 2. support column, 3. heat exchanger in figure, 31. volume adjusting apparatus.
Detailed description of the invention
As shown in Figure 1, indirect air cooling equipment, comprise the cooling tower 1 that bottom is provided with support column 2, bottom cooling tower 1, be also furnished with multi-group heat exchanger 3, heat exchanger is set to level.
As shown in Figure 1, heat exchanger 3 is arranged along the direction that the concentric circles radius with cooling tower 1 is parallel, multiple horizontally disposed heat exchanger 3 is arranged in cooling tower 1 radially, and quantity can adjust according to the size of cooling tower and cooling requirement, and each horizontally disposed heat exchanger 3 is triangle.The radiating fin that the two sides of heat exchanger 3 comprise pipe and are arranged on pipe, power plant in, the water to be cooled of outflow is cooled at Bottomhole pressure, and volume adjusting apparatus is arranged on bottom surface.Outside air enters from bottom surface, by volume adjusting apparatus, to contact and complete heat exchange with pipe with the radiating fin be arranged on pipe.
Heat exchanger can also adopt and be arranged vertically, it is arranged along the direction vertical with the concentric circles radius of cooling tower, multiple vertically arranged heat exchanger circumferentially shape around cooling tower, each vertically arranged heat exchanger is triangular prism shaped, three sides of the pipe of both sides and radiating fin and volume adjusting apparatus formation triangular prism, water to be cooled is at Bottomhole pressure and cooled, and volume adjusting apparatus is arranged on three faceted pebbles away from centre of cooling column.Outside air by volume adjusting apparatus from cooling tower surrounding, to contact with the radiating fin be arranged on pipe with pipe and completes heat exchange.
The volume adjusting apparatus of heat exchanger can be rolling screen door, vertical hinged door, hinged door, sliding door or structure of folding door, preferred rolling screen door and structure of folding door.As shown in Figure 2, for horizontally disposed heat exchanger, the volume adjusting apparatus of rolling-door structure comprises a body, guide rail, roller shutter box, spool, motor, wherein roller shutter box is arranged on the top of heat exchanger, and door body is connected by multiple sheets and formed, and can slide in guide rail, spool is arranged in roller shutter box, arrange tubular motor in the middle part of spool, tubular motor rotates centered by spool, with the folding and unfolding in fixing guide rail of driving gate sheet.During rising, door sheet is wound on spool, during decline under door sheet follows track sideslip.Motor is connected with the control system of cooling tower, the rising of a sheet, stopping, down maneuver is realized by the control of control system, the its stored position of door body can carry out in real time adjustment automatically according to ambient temperature and cooling requirement, thus the air-flow in control heat exchanger, and then maintain the preference temperature of heat exchanger.Badge can be lived the track end position when door is in opening by this external door, not allow during accident condition and glide; In the lower end of door body, hooking point is established at positive middle part, can adopt specific purpose tool that door is moved up and down; Establish bolt at the two ends, downside of door body, door can be made when door is in closed condition to be fixed on door pillar; On door pillar, differing heights establishes the point of some fixing bolts, makes door can rest on several height.
