Description

Antifreezing protection device of cross-flow cooling tower Technical Field The utility model relates to the technical field of cross flow cooling towers, in particular to an anti-freezing protection device of a cross flow cooling tower. Background A cross-flow cooling tower is a device that cools water. The water flow vertically falls from the upper part of the tower, the air horizontally flows through the water spraying filler, the air flow is orthogonal to the water flow, and the anti-freezing protection device of the cross flow cooling tower is mainly used for preventing circulating water from freezing in a low-temperature environment in winter and avoiding equipment damage. Common anti-freezing measures can be divided into two types, passive anti-freezing and active anti-freezing. The prior Chinese patent with reference number of CN219776404U provides an antifreezing square cross flow cooling tower, which comprises a square cross flow cooling tower body, wherein a group of air inlets are formed in the left side wall of the square cross flow cooling tower body, a group of air outlets are formed in the right side wall of the square cross flow cooling tower body, a filler is fixedly connected with the inner wall of the square cross flow cooling tower body, a guide plate is fixedly connected with the upper surface of the filler, two symmetrical antifreezing fluid discharging mechanisms are arranged in the square cross flow cooling tower body, and the two antifreezing fluid discharging mechanisms comprise conveying pipelines, and the outer surfaces of the conveying pipelines are fixedly connected with the inner wall of the square cross flow cooling tower body.
