Radar antenna cooling anti-adhesion device for high temperature dust measurement

Abstract

The invention relates to a radar antenna cooling anti-adhesion device for high temperature dust measurement, belonging to the field of high temperature radar survey. The device is characterized by comprising an adjustable radar heat insulation sleeve (1), a gas induct hole (2), a flange piece (3), an antenna inner cover (4) and an antenna outer cover (5); the processing length of the radar heat insulation sleeve can be adjusted, and the upper part of the radar heat insulation sleeve is provided with a cooled sink which has the functions of radar heat insulation and heat dissipation; the gas induct hole is externally connected with nitrogen pressure gas, and the pressure of the gas is 0.9-1.1kg higher than that near an antenna; the antenna inner cover takes on a horn shape, the outer coveris fixed on the inner cover and screwed down by screw thread or compressed by the flange piece, the antenna outer cover is parallel to the axis of the antenna by axial cylinder, and the inner cover istaken as an echo reflecting surface of a bellmouth of a radar. The radar antenna cooling anti-adhesion device has the advantages of good sweeping effect, long maintenance free time and the like, canbe used for the places needed to be swept and cooled, and is widely applied to the fields such as metallurgy, petrochemical engineering, etc.

Description

technical field [0001] The invention belongs to the field of high-temperature radar measurement, and in particular relates to a radar antenna anti-glue adhesion device, and also relates to a cooling and anti-dust device. Background technique [0002] The working principle of the anti-adhesion antenna is mainly used on the inner side of the horn antenna. By opening a number of small holes, the cooling or purge gas is introduced into the inner surface of the horn. Through the design of the purge angle, the introduced gas is inclined. Along the inner surface of the antenna, a sweeping airflow with a rotating effect is formed to clean the radar surface and resist the adhesion of pollutants. [0003] The design of the purge intensity and angle can be determined according to the degree of pollution, including the number, diameter, and inclination angle of the purge holes. The existing radars basically open a small hole near the radar antenna to directly purge the top of the inner...
