SU197231A1 - AUTOMATIC CONDENSATION DEVICE FOR MEASURING HIGH-TEMPERATURE GAS MOISTURE - Google Patents

Description

A known automatic condensation instrument for measuring the humidity of a high-temperature gas containing a condensation system, a float gauge of condensed liquid level, a reducer for stabilizing the flow rate of a groove, an exhaust solenoid valve and a recording instrument.

The proposed device differs from the known one in that it is equipped with a differential transformer system, in which an additional induction coil is introduced, kinematically connected with a thermometric chamber connected to a gearbox and a float level meter. This allows a correction for moisture entrained in the waste gases, depending on the temperature, and increases the measurement accuracy.

FIG. 1 shows a schematic diagram of the device; in fig. 2 - structural diagram of the thermometric system.

The measured hot gas, the passage through the coil /, is cooled and moisture is released from it, which flows into the measuring chamber 2. The cooled gas enters the thermometric system 3 through the connecting tubes, and then through the filter 4 - into the reduction gear 5. From the reduction gear stabilizing the gas flow is emitted to the atmosphere. The moisture level is measured with the help of the float 6 and the core 7 connected with it, moving in the induction coil 8. The measurement result is fed to the secondary device 9, the scale of which is calibrated in the dry gas ZPIHM.

Automatic moisture meter operates cyclically. The cycle is strictly limited in time and equal to 5 or 15 minutes. The cycle duration corresponding to the selected humidity range is carried out by the cycle controller 10. Io the expiration of gypsum time

The electromagnet 1 is turned on and opens the edge to drain the condensate from the measuring chamber 2. After the condensate has been descended and the chamber has been drained, the edge closes and a new cycle begins. Automatic switching

All stages of the cluster are produced by the electrical circuit of the instrument.

The gas passing through the condensation system is cooled by the air flow generated by the fan 12.

The temperatures of the ambient air and the gas being measured are different, and therefore the temperature of the exhaust gas is not constant. Depending on the waste gas treatment, different amounts of gas are carried along with it, and correction of the waste gas temperature is provided for.

The thermometric system (Fig. 2) consists of a chamber 13 and a sealed thermo-bottle 14 filled with methyloxy alcohol. A bellows 15 is welded to the top of the TCP cylinder. The gas leaving the measuring chamber 2 is passed through chamber 13. The alcohol in the thermal cylinder 14 takes the gas temperature and changes its volume. As a result, the sylphs 15 point moves and, through a system of levers, moves the core 16 of the induction coil 17. With this coil included in the differential-transformer circuit, the magnitude of the additional voltage entering the circuit varies depending on the temperature oTxo; i, nП1, er (o from the gas measuring chamber.

During calibration, the thermometric system is adjusted to the temperature of the exhaust gas (- | -30 ° C). When the temperature changes

the correction function is performed by the thermometric system within + 15 °.
