Abstract

The invention, mb, is used to cool the circulating water of industrial enterprises and makes it possible to increase the efficiency of heat and mass transfer in a cooling tower. The conical shell 10 is fixed on the lower edge of the diffuser 9, and the plate 12 - in the upper part of the housing 1 along its perimeter. With wind, the air with the help of the shell and the plate is directed to the confused channel 11, causing an increase in thrust in the cooling tower, a decrease in the load on the fan and an increase in air exchange in the cooling tower. 1 il.

The invention relates to contact apparatus and can be used to cool the circulating water of industrial plants.

The purpose of the invention is to increase the efficiency of heat exchange by increasing the draft in the cooling tower.

The drawing shows the fan of the cooling tower torn, a general view.

ij The turn-on valve of the cooling tower includes a housing 1 with air inlet ports 2 and a catchment basin 3 located in its lower part. The irrigation 4, the water distributor 5 and the water trap 6 are installed in the housing 1. On the upper part of the housing 1 is fixed. an exhaust device including a fan 7 with a fan 8 placed in its smallest section and a diffuser 9. At the lower edge of the diffuser 9 a conical shell 10 is fixed to form an annular confuser channel 11 with an outer contour of the confuser 7. on its perimeter fixed annular plate 12.

Hot water is fed to the water dispenser 5, sprayed onto the irrigator 4 and drained from it as a film. The air enters the housing 1 through the windows 2 and cools the water. The air, saturated with vapors and water droplets, flows further into the water incubator 6, where it is cleaned of water. By fan 8, air is drawn out of

Cases 1. The cooled water enters from the irrigator 4 into the pool 3 and then goes to the consumer.

With wind, the air is fed by the shell 10 and the plate 12 into the confused channel 11, where it accelerates and runs vertically upward into the diffuser 9, causing an additional increase in draft in the cooling tower, a decrease in the load on the fan and an increase in air exchange in the cooling tower.

Claims (1)

Formula A cooling tower turn tower containing a housing with air inlet windows and a catchment basin located in its lower part, installed in the case there is an irrigator, a water distributor and a water catcher, an exhaust device mounted on the upper part of the case, which includes a confuser with its smallest section a fan and a diffuser, which is - due to the fact that, in order to increase the heat exchange efficiency by increasing the draft in the cooling tower, the cooling tower is equipped with a conical shell and an annular plate, while the shell is fixed on the lower edge of the diffuser with the outer circumference confuser annular confused channel, and the plate secured in the upper part of the body along its perimeter.
