Abstract
A high temperature radar charge level indicator device for an active lime vertical type cooler. The high temperature radar charge level indicator device is a solid charge level indicator used in high temperature and dust environment, and is used for measurement of high temperature active lime material level in the active lime vertical type cooler. An installation vertical pipe is arranged at the central portion of the high temperature radar charge level indicator device, a guided wave pipe is arranged in the center of the installation vertical pipe, and the top of the guided wave pipe is connected with a radar charge level indicator. Downward sloping compressed air channels are evenly arranged on the installation vertical pipe near one side of the radar charge level indicator, and a guided wave pipe high pressure nitrogen channel is arranged at the guided wave pipe portion on the outside of a mounting flange. According to the charge level indicator, the extended installation vertical pipe is used, so that distance between the charge level indicator and high temperature materials is increased, and direct radiation effect of high temperature on the radar charge level indicator in the cooler is reduced. Two stage compressed air/ high pressure nitrogen purging is used, so that cooling effect of the radar charge level indicator is greatly improved, and service life of the charge level indicator is prolonged by more than two times. The high temperature radar charge level indicator device is simple in structure, safe and reliable, convenient to carry out, and low in cost. Moreover, the compressed air is mainly used to purge.
Description
Technical field
The utility model belongs to the instrument for automatic control field, particularly relates to a kind of active lime shaft cooler high temperature radar level gauge device.Be a kind of leve meter for solid matter of using in high temperature, the dust atmosphere of being applicable to, be used for the measurement of high temperature active lime material level in the active lime shaft cooler.
Background technology
On the shaft preheater-rotary kiln of production active lime-shaft cooler production line, temperature reaches 900 ℃ when entering shaft cooler through the lime behind the calcined by rotary kiln, the cooling air cooling that is blasted by overfire air fan in refrigeratory is discharged after about 100 ℃, simultaneously, cooling air is by carrying out entering the combustion-supporting burning of rotary kiln after heat interchange is preheated to about 600 ℃ with lime.Therefore, refrigeratory top is in high temperature, high dust atmosphere, special high temperature resistant radar level gauge for the inner controlling level of monitoring refrigeratory, affected often by scaling loss by this high temperature, high dust atmosphere, only have three months serviceable life, increased spare parts consumption and maintenance cost, level-sensing device even output spurious signal have a strong impact on the operation operation of measurement effect and system sometimes.
Summary of the invention
The purpose of this utility model is to provide a kind of novel active lime shaft cooler high temperature radar level gauge device, has further improved the cooling-down effect of radar level gauge, improves its serviceable life.
The utility model high temperature radar level gauge device, heart position is an installation standpipe therein, and it is opening towards outside material level one end that standpipe is installed, and the other end is mounting flange.At installation standpipe center one waveguide pipe is arranged, waveguide pipe is inserted in by mounting flange and installs in the standpipe.The waveguide pipe top links to each other with radar level gauge.Near on the installation standpipe of radar level gauge one side, uniform downward-sloping compressed air channel is set, form nozzle in the inflow point that standpipe is installed.Waveguide pipe in the mounting flange outside partly is provided with waveguide pipe high pressure nitrogen passage.
The utlity model has following advantages:
1, the level-sensing device device adopts the installation standpipe that lengthens, and towards material level one end steel pipe opening, the other end and the welding of level-sensing device mounting flange strengthen the distance between level-sensing device and high-temperature material, has reduced the direct radiation effect of the interior high temperature of refrigeratory to radar level gauge.
2, the level-sensing device device is installed standpipe and at the body near level-sensing device one side 4 uniform compressed-air atomizers is set, injecting compressed air, form local positive pressure environment, the radar level gauge that rises to that stops the interior hot blast of refrigeratory, to reduce the bell-mouthed temperature of radar level gauge waveguide pipe, reduced the impact of high temperature on radar level gauge.Simultaneously, sealing function is played in the compressed-air actuated injection of large flow simultaneously, stops that the high-temperature dust in the refrigeratory enters the installation standpipe and is infected with radar level gauge radar wave emission original paper.
3, the level-sensing device device exposes waveguide pipe at radar level gauge partly increases waveguide pipe inner high voltage nitrogen blowing, makes and is filled with high voltage protective nitrogen in the waveguide pipe, has further reduced the impact of high temperature on radar level gauge, the protection radar level gauge.
4, the level-sensing device device adopts pressurized air to purge, and the pressurized air that passes into mutually is without requirements such as humidity, dust degree, and cheap with respect to other gas mediums, cost is lower.The cooling air that this pressurized air uses refrigeratory overfire air fan to bloat need not to dispose separately air compressor machine or blower fan, and is entered by refrigeratory and also can be used as auxiliary air behind the rotary kiln and help burning.
