Abstract
The utility model relates to a novel arrangement system for wet-type cooling tower filling materials, belongs to the fields of thermal power generation and nuclear power generation, and especially relates to a novel arrangement system adopted to raise cooling efficiency of a natural ventilation reverse-flow wet-type cooling tower. A non-uniform arrangement is adopted in the novel arrangement system, i.e., an arrangement system with non-uniform height is adopted for the filling materials along a diameter direction of the wet-type cooling tower. Filling materials in a central position of the wet-type cooling tower is the thinnest, the filling materials in an outer edge of the tower is the second thinnest, and the filling materials in some diameter range in the middle is the thickest. In this manner, heat and mass transferring properties at everywhere inside the tower are balanced, an aerodynamic field inside the tower is improved, an optimal matching of air distribution and filling material inside the cooling tower is met, and cooling efficiency of the cooling tower is raised. The technology is applicable to the filling material arrangement of large-scale wet-type cooling towers.
Description
Technical field
The utility model belongs to thermal power generation and nuclear electric power generation field, particularly relates to a kind of new arrangement system of the filler taked for the cooling effectiveness that improves the contrary wet cooling tower of gravity-flow ventilation.
Background technology
Present domestic thermal power plant (comprising the atomic power plant) the main flow tower that cooling tower adopted is a gravity-flow ventilation adverse current wet cooling tower; To be filler arrange that evenly the different radii place is and waits high layout in that cooling tower is inner to the conventional design of gravity-flow ventilation adverse current wet cooling tower filler.Along with the increase of unit capacity, the cooling tower volume is also increasing, and the area of packing area is also increasing, and as far as the 100MW unit, filling area reaches 12000m
2, so big cooling tower area is difficult to guarantee the even ventilation of packing area.After ambient wind got into from cooling tower bottom air inlet mouth, the process of flow through rain belt and packing area was one and absorbs heat gradually and the process of moisture absorption; The closer to the cooling tower center, the temperature of humid air is high more, and humidity is big more; The heat absorption capacity variation causes cooling tower inner air flow velocity skewness, produces whirlpool; Destroy the air force field distribution in the tower, caused the cooling effectiveness of cooling tower to reduce.
The utility model content
The utility model is in order to address the above problem; Overcome existing wet cooling tower filler and arrange existing problem; A kind of new arrangement system of wet cooling tower filler is provided, and the even aerodynamic field in the tower is given full play to the heat and mass transfer performance of filler; Improve the cooling effectiveness of cooling tower, reach the optimum Match that tower inner air-distributing and filler are arranged.
The utility model is realized in the following manner:
A kind of new arrangement system of wet cooling tower filler, filler adopts non-homogeneous layout in the wet cooling tower, and subregion arranges, promptly takes a kind of high arrangement system such as non-from inside to outside along the diametric(al) of wet cooling tower.
Said filler is divided into three districts from inside to outside along diametric(al): I district filler is the thinnest, is positioned at the center of cooling tower; II district filler is the thickest, is positioned at intermediate range; III district depth of packing takes second place, and is positioned at the outer part of cooling tower.
The district filler radius is: I District filler radius:?
II zone radius filler is:?
III zone radius filler: R3 = R; R1 <R2 <R3, where R is the radius of the cooling tower fill area.
The said thickness range of respectively distinguishing filler is: the thickness range of I district filler: h
1=0.75 δ ~ 0.85 δ, II district depth of packing scope is: h
2=1.15 δ ~ 1.3 δ, III district depth of packing scope is: h
3=0.85 δ ~ 0.95 δ, wherein δ is the design depth of packing of cooling inner-tower filling material when taking even arrangement system.
Outside air is the process of a heat absorption moisture absorption gradually in the process that gets into the wet cooling tower center, and after outside air got into wet cooling tower inside, temperature raise, and water capacity increases, and the heat absorption wettability power weakens, and heat and mass transfer performance reduces.The closer to the wet cooling tower center, the temperature of humid air is high more, and humidity is big more, and the heat absorption capacity variation causes wet cooling tower inner air flow velocity skewness, produces whirlpool.In order to reduce the resistance of center, reach each regional balance, need reduce the depth of packing of center; The place, outer of wet cooling tower, because ventilation is relatively low, so depth of packing takes second place; Midway need make full use of the heat and mass transfer performance of filler, increases the heat absorption wettability power of air as much as possible, therefore needs to increase depth of packing.The utility model is owing to adopted the non-height that waits of respectively distinguishing filler to arrange; Can give full play to the heat and mass transfer performance of inner-tower filling material; Under the prerequisite that does not increase the cooling tower flowing resistance; Improve the aerodynamic field in the tower, satisfied the Optimum Matching of inner air distribution of cooling tower and filler, improved the cooling effectiveness of cooling tower.
