Embodiment Construction

[0018] Below in conjunction with accompanying drawing, working principle, concrete structure and implementation of the present invention are further described:

[0019] figure 1 It is a structural schematic diagram (front view of the windward side) of an embodiment of an air-cooling tower equipped with a wind-receiving room in the present invention. The air-cooling tower includes an air-cooling tower shell 1, a bottom air inlet 2, and at least one air-cooling tower arranged outside the bottom air inlet. The air chamber 3 and the air receiving chamber 3 are arranged along the circumference of the air cooling tower. The air receiving chamber 3 is open to the direction of the incoming ambient wind, and is closed on the leeward side. It is preferable to arrange two air collection units, one on each side of the air cooling tower. The height of the upper edge, the width of the side extension, and the depth along the wind direction of the air collection chamber can be comprehensivel...

Abstract

The invention discloses a cross wind recycling type air cooling tower and relates to a device for conducting flow guide utilization on environmental wind of an air cooling unit of a power station. The air cooling tower comprises an air cooling tower shell, a bottom wind inlet and at least one wind collecting room arranged on the outer side of the bottom wind inlet. The wind collecting rooms are arranged in the circumferential direction of the air cooling tower and are opened in the incoming flow direction of the environmental wind and are closed on the leeward side. At least one cross wind flow guide structure is arranged on the leeward side of the air cooling tower. Each cross wind flow guide structure comprises an inlet wind flow guide section, a ventilation pipeline and a back outlet wind flow guide section, wherein the inlet wind flow guide section is opened in the incoming wind direction and is arranged on the upper side of the corresponding wind collecting room along the air cooling tower shell. By means of the cross wind recycling tower air cooling tower, due to the arrangement of the wind collecting rooms, the cross wind flow guide structures, wind blocking walls and the like, power sources of environmental cross wind are circumferentially arranged, the circumferential uniformity of inlet wind at the bottom of the air cooling tower under the environmental wind condition is improved, a flow field structure in the air cooling tower in the cross wind environment is improved, and therefore the ventilation characteristic and the cooling performance of the air cooling tower are further enhanced.

Description

technical field [0001] The invention relates to a structural design of an air cooling tower, in particular to a device for guiding and utilizing the ambient wind of an air cooling unit in a power plant, and belongs to the technical field of air cooling equipment. Background technique [0002] The air cooling tower is the key equipment of the indirect air cooling unit in the power plant, and it is a necessary condition to establish the vacuum of the steam turbine and take away the heat source of the cold end. However, due to the existence of environmental crosswinds and the uncontrollability of its direction and wind speed, it has brought great challenges to the economical, safe and stable operation of the unit. [0003] The environmental side wind will mainly destroy the pressure field and flow field environment at the inlet and outlet of the air cooling tower, form a vortex flow inside the air cooling tower, and deflect the air flow at the outlet of the air cooling tower, r...
