specific Embodiment

[0044] The specific example is as follows: at the air inlet of the cooling tower, 10 air passages are evenly arranged radially along the circumference, one end of the pipe is located at the air inlet of the cooling tower, and the other end is located at the center of the cooling tower. The air duct is tapered from the outer end to the inner end, and the cross-section of the air duct is designed to be rectangular or arched. Among them, 5 are long air passages with a length of 45 meters; 5 are short air passages with a length of 35 meters, and the lengths are staggered. The height of the air inlet of the ventilation duct is 5 meters, and the width of the air inlet of the ventilation duct is 10 meters. In this way, when the cooling tower is running, a part of the cold air enters the center of the cooling tower along the ventilation channel. Because there is no heat exchange process outside the rain area, this part of the cold air has a large momentum and low temperature, which ca...

Abstract

The invention provides a natural ventilation wet type cooling tower ventilation device, and belongs to the technical field of heat exchange devices. The device comprises a plurality of ventilation channels. The ventilation channels are evenly distributed in the radial direction of the circumference of an air inlet of a cooling tower, the cross sections of the ventilation channels are in an arch shape, and the cross sections of the ventilation channels are decreased from the exterior to the center of the air inlet. According to the natural ventilation wet type cooling tower ventilation device,a ventilation duct is additionally arranged inside the cooling tower, cold air can be directly fed into the center of the cooling tower, the blast capacity and the air speed of heat exchange in the center of the cooling tower are increased, the heat transfer of the central region of the cooling tower is effectively enhanced, the outlet water temperature is lowered, and the efficiency and economical efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and more specifically relates to a ventilation device for a natural ventilation wet cooling tower. Background technique [0002] The cooling towers of the existing units all directly take in the air from the air inlet, and the cold air gathers from the periphery to the central area and then flows to the upper part of the cooling tower. When the natural ventilation wet cooling tower is in operation, the cold air entering the cooling tower will first pass through the rain area. In the rain area, the cold air exchanges heat with the high-temperature condensed water, thereby losing part of the kinetic energy and increasing the temperature of the cold air. This leads to poor heat transfer performance after the cold air enters the central area of ​​the cooling tower, and cannot effectively cool the central area. This kind of heat transfer distribution with good heat transfer around the...
