A certain number of air supplement tubes are arranged at an air inlet in the bottom of the cooling tower, the air supplement tubes extend from the outer edge of the air inlet of the cooling tower to the central area, the air supplement tubes are in an arch shape or a circular shape or a quadrangle shape or a triangle shape or a semicircle shape or an arch shape, and a layer of soft rubber pad is laid at the upper portions of the air supplement tubes. The cooling tower is characterized in that the air supplement tubes are unevenly arranged according to surrounding air speed, air direction and the distribution situation of buildings around the tower. According to the cooling tower, it is ensured that the air dynamic field and the temperature field inside the space of the whole cooling tower can be more uniform, the ventilation quantity of the cooling tower is larger, the whole cooling tower has the better heat transfer effect, the cooling efficiency is effectively improved, and the temperature of circulating water is reduced.
Description
One, technical field
The utility model belongs to thermal power generation and nuclear electric power generation field, particularly relates to a kind of new-type reverse flow wet type cooling tower that has added secondary air channel.
Two, background technology
The natural draft counter-flow wet cooling tower profile using is at present hyperbolic-type, bottom surrounding natural air inlet.Recirculated water enters cooling tower filler layer position and flows downward, and air upwards flows from bottom inlet, and the heat of absorption cycle water completes the process of heat and mass transfer, and the temperature of recirculated water is reduced.Along with cooling tower volume is increasing, drenching area reaches 10000m
2above, the diameter of air inlet has exceeded hundred meters, and this certainly will cause in cooling tower heat and mass intensity inequality, the especially heat transfer effect of cooling tower middle section everywhere to weaken the most obvious.
Under environment crosswind, the air intake of cooling tower is worse off, and ventilation reduces, and the uneven situation of the power in inner aerodynamic field and temperature field further aggravates, and this greatly reduces the cooling performance of traditional cooling tower.
Some are with bottom air inlet fairing cooling tower at present, the air ducting just being formed by longitudinal baffle or lateral partitions with a circle in air inlet periphery, this can alleviate the impact of extraneous crosswind for cooling tower air intake, and the heat transfer effect of cooling tower middle section still a little less than.In prior art, generally adopt and be evenly arranged guide duct simultaneously, it is not also suitable for all occasions.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existing equipment technology, a kind of new-type natural draft counter-flow wet cooling tower with secondary air channel is provided, the heat transfer effect of the middle section of this cooling tower is enhanced, and in tower, heat transfer intensity is more even, has higher cooling effectiveness.
The utility model is achieved in the following ways: a kind of cooling tower with secondary air channel, be furnished with the secondary air channel of some at the air inlet place of described cooling tower bottom, extend to middle section by cooling tower air inlet outer rim, wherein secondary air channel be shaped as arch door shape, circle, quadrangle, triangle, semicircle or arch door shape, described secondary air channel top is covered with the soft rubber blanket processed of one deck, it is characterized in that, described secondary air channel carries out layout heterogeneous according to ambient wind velocity, wind direction, all structures distribution situations of tower.
The physical dimension of described secondary air channel is: longitudinally full-size M is: h/3≤M≤2h/3, horizontal maximum size N is: l/2≤N≤l, and length L is: R/2≤L≤R, wherein h is cooling tower air inlet height, l is cooling tower air inlet herringbone column maximum spacing, and R is cooling tower bottom radius.
The new-type cooling stack with secondary air channel that the utility model is set forth, after employing, can guarantee that aerodynamic field and temperature field in whole cooling tower space are more even, the ventilation of cooling tower is larger, cooling tower entirety has better heat transfer effect, effectively improve cooling effectiveness, reduce the temperature of recirculated water.
