Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Such as Figure 1-4 As shown, the present invention is a high-temperature-resistant self-cleaning anti-corrosion microwave antenna, which includes an outer sleeve 1, an antenna inner cover 2, a flange piece 3, a heat sink 4, a water inlet joint 5, a water outlet joint 6, and a PTFE antenna rod 7. High temperature protective coating 8, water cooling cover 9, water cooling pipe 10, air cooling cavity 11, microwave channel 12, wave transparent material plate 13, air inlet joint 14, air inlet 15, flow detection device 16, and gas flow Count 17.

[0031]The upper end of the outer sleeve 1 is welded with the flange piece 3; the antenna inner cover 2 is placed in the outer sleeve 1, and the upper end is threaded with the flange piece 3; the inner surface of the antenna inner cover 2 is coated with a high-temperature protective coating 8, and ...

Abstract

The invention belongs to the technical field of high-temperature industry related measurement facilities and particularly relates to a self-cleaning microwave antenna with resistance to high temperature and corrosion. The self-cleaning microwave antenna comprises an outer sleeve used for installation, an antenna inner cover, a flange plate, a cooling fin, a PTFE (Polytetrafluoroethylene) antenna rod, a water-cooling cover, an air-cooling cavity, a wave-transmitting material plate, and the like. The invention has the beneficial effects that both a horn and a microwave reflection plane of the integral antenna are made from high-temperature-resistant self-cleaning ceramic materials so that the integral self-cleaning microwave antenna has strong temperature tolerance; the antenna is of a single-layer, double-layer or multilayer nested type cooling structure, a water-air mutual-separation and co-cooling closed structure is adopted according to the requirement of total cooling quantity, the air-cooling cavity plays a blowing role at the same time of playing a cooling role so as to form a rotation air flow to remove deposited dust on the inner surface of a radar and guarantee the cleanness of the surface of the wave-transmitting material plate, and an adherence resistant function is also fulfilled; and on the premise of meeting the requirement on the total cooling quantity and taking the balance between nitrogen-cooling expense and water-cooling expense into consideration, a thermal balance is achieved for the cooling quantity between water cooling and air cooling, and the advantages of large volume and fast temperature drop are achieved by applying water cooling to save nitrogen.

Description

technical field [0001] The invention belongs to the technical field of high-temperature industry-related measurement facilities, and particularly relates to an antenna structure with high-temperature-resistant, self-cleaning and anti-dust devices for ironmaking blast furnace roofs or coke ovens and other high-temperature furnace microwave detection devices. Background technique [0002] The process of blast furnace smelting in the iron and steel industry is a continuous smelting process, in which the shape of the furnace top distribution needs to be continuously detected - to obtain real-time and accurate three-dimensional material surface shape information in the blast furnace and control the distribution method and blast furnace gas distribution. It plays a very important role in judging the furnace condition. At the same time, the three-dimensional material surface shape information and acquisition are very important for controlling the activity of the hearth, ensuring the...
