Description
Technical field:
The present invention relates to thermal power generation and nuclear electric power generation field of engineering technology, be specifically related to a kind of gravity-flow ventilation cooling tower center conditioner and control method.
Background technology:
The gravity-flow ventilation wet-type countercurrent cooling tower in thermal power plant and nuclear power station, is the equipment of cooling circulating water.General hyperbola rotary shell (tower tube) pattern that adopts, housing is supported along the equally distributed herringbone column of circumference by the bottom.The ring beam of herringbone column top and housing joins, and the bottom is supported by cyclic group.Build the pool wall of grade water on the cyclic group, form collecting-tank.Constitute the tower core by parts such as trickle framework, packing, water distribution system, dehydraters in the housing.The space that the ring beam on herringbone column top and collecting-tank pool wall top form is exactly the air inlet of water tower.
It is generally acknowledged, the height of cooling tower, throat diameter, the air intake vent height, packing model, area and height, after the water tower base diameter was determined, the cooling capacity of a cooling tower is just basic to have been determined.But the effect of cooling also is subjected to environment, season, wind direction, wind-force, the dry humidity of air, the air flow direction, the uniformity (distribution) in water tower, size and intensity between flow velocity, vortex, the influence of factors such as generated output and cooling water inflow.
20th century the nineties, find traditional double-curve cooling column, in the process of cooling circulating water, have the vortex in the hyperbola tower, this vortex accounts for 1/3 of water tower inner space.The existence of vortex has obviously reduced the cooling effectiveness of double-curve cooling column.
China ZL200620021246.8 patent, invented the air generation plants that installs guide plate at the water tower air intake vent additional, the air that enters water tower is oriented in a tangential direction to be entered, rise at the inner eddy flow that forms of water tower, reduced the vortex of water tower inside, improve the air force condition of water tower inside, improved the cooling effectiveness of water tower.Discover, after water tower installs guide plate additional, though improved the cooling effectiveness of cooling tower, but in the water tower center, still the air zone that has a high humidity high temperature, this regional cooling effectiveness is obviously on the low side than other zones, illustrates that the cooling effectiveness of water tower also has the potentiality that improve.
Summary of the invention:
The purpose of this invention is to provide a kind of gravity-flow ventilation cooling tower center conditioner and control method,, improved the cooling effectiveness of cooling tower by the setting of air regulating channel connection conditioner.
Above-mentioned purpose realizes by following technical scheme:
Gravity-flow ventilation cooling tower center conditioner, its composition comprises: install the water tower of guide plate additional, conditioner is equipped with in the packing area of described water tower tower core, is air regulating channel between described packing area and the described conditioner.
Described gravity-flow ventilation cooling tower center conditioner, described passage horizontal section is annular or polygonal annular, or described passage is a comb.
To be ball crown type or fairshaped adjusting plate washer or the hollow round platform with coaxial adjusting plate washer or described conditioner be two coaxial not contour cones up and down for described gravity-flow ventilation cooling tower center conditioner, described conditioner.
Described gravity-flow ventilation cooling tower center conditioner has one group of support member pad and is connected on the described passage on the described conditioner.
The method of gravity-flow ventilation cooling tower center air conditioning, on the air regulating channel of the center of described water tower tower core, conditioner is installed, 5%～45% gap of controllable register diameter is stayed at described conditioner and described air regulating channel top, is used for regulating air mass flow and speed.
Beneficial effect of the present invention:
1. the present invention is in the center of gravity-flow ventilation cooling water Tata core, design a kind of air regulating channel, and installation conditioner, the water tower that helps installing additional behind the guide plate improves cooling performance, this device makes the hot and humid air of water tower center by this passage, directly enter filler top, improved the lifting buoyancy of water tower inside, thereby make fresh relatively, the air that temperature is lower enters the center faster, improved the center intensity of heat exchange of water and air on every side, by adjustment to gravity-flow ventilation cooling tower center aerodynamic field, realize that the air force sports ground changes, and then improved the cooling effectiveness of cooling tower, be a kind of energy-conservation technology.
2. along air duct conditioner, flow and the speed that can regulate air are installed.The diameter of this passage, different according to water tower design parameter and liquid distribution are chosen different values by experiment, generally can choose 0.02 to 0.12 of packing effective diameter.Passage may spatially intersect or conflict with parts such as trickle framework, packing, water distribution system, dehydraters, can take to remove part filler, dehydrater, with ways such as pipeline perforations, guarantees the circulation area of air duct.
