Problems solved by technology

[0003] However, since the air condenser is exposed to the air and directly exchanges heat with the surrounding air, the combination of different wind directions, wind speeds, and air temperature will inevitably have a great impact on the normal operation of the air condenser, which will cause the back pressure of the steam turbine to increase. A large increase will reduce the power generation efficiency, which may cause shutdown in severe cases and adversely affect the operation of the steam turbine

Embodiment

[0021] A windproof device 1 for improving the heat dissipation efficiency of a direct air cooling system, comprising a support frame 3, a base of the support frame 3, a wind barrier blade 4 installed on the support frame 3, and a wind barrier blade opening system.

[0022] The wind barrier blade 4 is provided with an air guide hole 5, and the opening rate of the air guide hole 5 on the wind barrier blade 4 is 20%-60%.

[0023] The wind barrier blade opening system is composed of an anemometer, a thermometer, a computer-controlled instrument and an opening device. The anemometer and the thermometer are connected to the computer-controlled instrument, and the computer-controlled instrument is connected to the motor of the opening device.

[0024] After the wind speed, wind direction angle and other data are obtained through the anemometer and the thermometer, they are transmitted to the computer controller, and the control system calculates and sends instructions to the opening d...

Abstract

The invention discloses an anti-wind device improving the heat exchange capability of a direct air-cooling unit. The device comprises a windbreak blade and is characterized in that the device is arranged in a cross shape under an air-cooling platform of the direct air-cooling unit in a thermal power plant, the length and the width of the device are the same with those of the air-cooling platform, so that the lower side of the air-cooling platform is sealed totally. Vent holes with certain aperture ratios and different diameters are formed on the windbreak blade, a windbreak blade opening system is arranged on the device and can adjust the opening area and angle of the windbreak blade automatically according to different wind speeds and wind direction angles, therefore the heat exchange efficiency of the air-cooling system is improved effectively, the backpressure is reduced, the electric energy production is improved, energy is saved, and emission is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection and energy saving, and specifically relates to a windproof device for improving the heat dissipation efficiency for the problem that the direct air-cooling unit of a thermal power plant is affected by the strong wind and the heat exchange capacity is reduced. Background technique [0002] my country's water resources are relatively poor, and water conservation and protection of water resources are increasingly being highly valued. In the coal-rich and water-poor areas in northern my country, many power plants currently use direct air-cooling systems due to the superior water-saving properties of air-cooling technology. [0003] However, since the air condenser is exposed to the air and directly exchanges heat with the surrounding air, the combination of different wind directions, wind speeds, and air temperature will inevitably have a great impact on the normal operation of the air condense...
