Abstract
As the working state of an industrial rotary kiln is rotating around central axis during production, a large amount of field wiring needs to be carried out when power supply and data acquisition are carried out on an instrument in the case of the traditional wired temperature monitoring, mounting of the instrument is thus limited, and inner temperature of the kiln can not be measured. In view of the above field conditions, a multi-way multi-point wireless WIA temperature measuring system is adopted for monitoring the inner temperature of the rotary kiln, which is a good solution method. Multiple measuring sections are selected inside a kiln rotary body, each measuring section is uniformly provided with multiple points in the circumferential direction, each direction is provided with a sheath protection sensor for acquiring the inner temperature of the rotary body, and the wiring end of each sensor is led out via a flange at the sheath end. The wireless instrument is fixed on the rotary body to rotate along with the kiln. A receiver is arranged inside or outside a control room, and an antenna is led to a region which can well receive signals of the instrument.

five, embodiment
Wherein armoured thermocouple is installed in the inner core of rotary kiln; this inner core is the equipment of turning; converter divides multistage (for six sections); set multiple measurement point (for 3 points for measuring temperature) for every section; they are positioned on the face, transversal garden of every section; and between two between angle be 120 °; material in converter is carbon granules (wheat size) and oxidation air; carbon granules has abrasive force; the wall of therefore interior stove devises 3 protective casings; the axis parallel of its axle center and converter, the multi-point armoured thermocouple (thermal resistor) installing in every root protective casing at 6 is even.In converter, the long-pending thick general of carbon granules is 1/3 of converter diameter, armoured thermocouple is mainly used to the temperature measuring carbon granules, when armoured thermocouple is in rotation process, the duration be embedded in carbon granules is probably 11 ~ 15 seconds, therefore requires that thermopair is not more than 10 seconds from measuring the time that is stable, accurate temperature after a kind of material enters another kind of material.
At converter every section point for measuring temperature; protective casing all designs a flange port; specification is DN50; Flange Standard is: HG/T20592 flange S050-6RF (according to the situation); and the measuring junction that supplier should be each measurement point provides a slice blind flange, the standard of blind flange and specification are: HG/T20592 blind flange 50-6RF, and the material of blind flange should be identical with equipment; the material of oxidation furnace is 16Mn, and the material of carbonization furnace is OCr25Ni20.
Can this device product quality up to standard, and key is oxidation furnace, material measuring tempeature and control in carbonization furnace.According to technological requirement, at oxidation furnace, carbonization furnace converter be axially evenly arranged from charging aperture to discharging opening 3 groups totally 18 temperature measuring points, each group arrange three temperature measuring points along cylindrical shell ring-type 120 ° of angles, consider safe and reliable, be convenient to safeguard, point for measuring temperature selects single E even, so every platform converter has 18 temperature signals need draw into DCS altogether.
Signal is introduced to the connected mode of pulpit from converter slip ring and wireless transmission two kinds.According to the feature of this device, our recommendation transmission of wireless signals mode, temperature that every platform is wireless becomes can connect the even temperature signals of 3 E, and a stove only needs 6 wireless temperature to become.Because: if with slip ring, every platform converter has 18 measurement points, and signal lead has tens, then slip ring needs tens slideways, and such slip ring is not only difficult to accomplish that slideway seals, and volume is very large, and cost is very high.Add slip ring completely outdoor, failure rate is high, and contact resistance often changes, and signal is not easily stablized, and measuring error is very large.
