)。The principle of a classical psychrometric hygrometer using a soft-bulb temperature trace sensor and its vapor moistened with a liquid contained in the measuring gas is also not available. Wet-bulb temperature sensors are surrounded by a porous material that is moistened with a liquid only once (prior to measurement) or continuously, in which case it has recently been moistened with vapor contained in the measuring gas. Condensate liquids have also been used (see, for example, European Patent Application No. 14809). The supply of liquid to the wet bulb temperature sensor, either by capillary action in a porous material or by a tape carrying the liquid and in contact with the sensor, is difficult to achieve when the temperature is high and therefore the evaporation rate is high, and when the measured gas is contaminated. It turns out that this is not enough. For this reason, it has been proposed to periodically immerse the wet-bulb temperature sensor in a liquid bath, but this, of course, cannot be used for continuous measurements (see French Patent No. 7,705,941).

う。When heat and mass transfer takes place in a bubble column (e.g. US Pat. No. 2,302,528 or PCT
(see patent WO 82102771), the measuring device has excessive wear and tear, excessively rapid liquid contamination and associated high monitoring costs. The same can be said for devices with fluidized beds or devices for splashing liquid onto the sample gas (Research paper 2145 J, Res, Nat.
If the heat and mass transfer takes place at the liquid surface which is flushed with the measuring gas, the surroundings of the measuring device may be slightly In order for the wet-bulb temperature reading to be influenced by the temperature with little delay, the strength of the transmission process must be very high. This condition is not met if the liquid inside the flat shell is washed along its surface, as is the case for example in DE 12 27 692. However, this is not the case when the liquid surface is supplied with a rebound flow of measuring gas.

ンサーはノズル開口と液体表面どの間に位置し、湿球温
度センサーは液体表面の下側に深く位置している。At the bottom of the thermally insulated container there is a ring made of porous material and containing a liquid that is supplied with a rebound flow. The measuring gas flows out of the nozzle in the container lid without swirling, is guided radially across the liquid surface, and flows out of the container tangentially above the container bottom. Liquid is fed under small pressure through a capillary tube placed around the ceramic ring. Since the amount of liquid supplied is determined to be greater than the amount of evaporation J: excess liquid carries away dirt from the liquid tank. The dry bulb temperature sensor is located between the nozzle opening and the liquid surface, and the wet bulb temperature sensor is located deep below the liquid surface.

供給毛管の測定ガスの供給は横への測定ガスの排出に関
して最少であるので、多孔質リングの外側壁および供給
毛管内にある液体の熱絶縁ないし加熱が十分ではない。After deflection over the liquid surface, the measuring gas flow is not guided radially by the vessel wall. This results in recirculation and mixing within the container, which has the effect of increasing the display delay of the measuring device. Since the supply of measuring gas in the outer wall of the porous ring and in the supply capillary is minimal with respect to the lateral discharge of the measuring gas, there is insufficient thermal insulation or heating of the liquid present in the outer wall of the porous ring and in the supply capillary. .

に相応した種々の湿球温度が生ずる。液体表面がひどく
汚れている場合、勿論新鮮な液体の強い供給は十分にで
きない。Since the liquid supply is adapted to the degree of contamination of the measuring gas in order to self-clean the liquid, different wet bulb temperatures corresponding to the contamination occur under the same measuring gas conditions. Of course, if the liquid surface is very dirty, a strong supply of fresh liquid will not be sufficient.

サーの位置との間に大きな温度差を生じてしまう。The liquid surface has irregular wavy characteristics. The wet bulb temperature sensor must therefore be located at a fairly large distance from the temporally averaged liquid surface, which results in large temperature differences between the liquid surface and the location of the sensor.

とするものである。The purpose of the invention is to continuously and accurately measure the vapor content of contaminated hot to hot gases. It also eliminates the disadvantages of conventional devices, requires minimal monitoring costs, has a small time constant, and is therefore suitable for continuous measurement, monitoring, and for controlling or adjusting the steam content. The aim is to obtain a measuring device that can be used as a transmitter. Furthermore, the aim is to analyze processes in energy-consuming plants and, as an additional device, to obtain a measuring device which can be operated economically in a way that is not possible with previously known devices.

It consists in controlling or adjusting. Also, a lithium chloride dew point meter, a fluid oscillator, a classic psychrometric hygrometer or an improved psychrometric hygrometer with a bubble column, a fluidized bed or a scattering device, or a wet bulb temperature sensor in a classic psychrometric hygrometer are sufficient. In the rebound flow type wet-bulb hygrometers mentioned at the outset, the sensitivity of gas-borne dirt is improved by means of bubble columns, fluidized beds or splatter devices, or with liquid flushed longitudinally. To eliminate the drawbacks of the above-mentioned rebound flow type psychrometric psychrometric hygrometers, which have a delay in display and both types of inaccuracy, which are conditioned on the interaction of the liquid with the surroundings and the supply. It is in.

A measuring chamber with a wet bulb temperature sensor is concentrically separated from a measuring chamber having a wet bulb temperature sensor and a supply chamber positioned around it by a partition wall, and a flat liquid tank that does not protrude from the t is hung at the bottom of the container. A rebound flow type psychrometric/wet-bulb hygrometer is equipped with a ring-shaped flow path around the liquid tank for discharging the measurement gas and liquid, and automatically and intermittently depending on the dry-bulb and wet-bulb temperatures.

直ぐ近くに位置している。In some cases, the measuring gas stream, which is kept at a constant temperature by regulating heating, is rotated in a swirl generator and the liquid in the liquid bath is rotated vertically from above in the form of a rebound flow that swirls out of the nozzle. supplied to After deflection at the liquid surface, the measuring gas is guided by the container lid and the wall of the container body and is returned to the outer wall or to the object to be measured through a channel provided around the liquid reservoir in the bottom of the container. Recirculation of the rebound flow into the interior of the wet-bulb hygrometer is thereby prevented; the dry-bulb temperature sensor 9- is supplied with only a fresh flow of measuring gas at the nozzle opening, and the wet-bulb temperature sensor is supplied with only a fresh flow of measuring gas at the nozzle opening. in the immediate vicinity of the rotationally stabilized liquid surface in the measuring chamber.

供給液体の合理的な消費を生ずる。The liquid supply is automatically metered intermittently from the storage tank under pressure and is controlled by the dry-bulb and wet-bulb temperatures to tangentially adjust the direction of liquid rotation in the tank, corresponding to several times the evaporation rate. The liquid stream is then periodically fed into the outer chamber of the liquid tank, while the liquid flow periodically transports the dirt that collects in the liquid tank by centrifugal force into the annular channel for gas exhaust at the bottom of the tank, from where it collects any excess contaminants. The evaporated liquid is carried away by the measuring gas flow, and the evaporated amount in the measuring chamber of the liquid tank is replenished via the slightly permeable liquid tank partition. As a result, the liquid supply measurement does not affect the wet bulb temperature and the liquid purification is greatly enhanced. The supply control of the liquid to be evaporated to a higher or higher degree, which can be adjusted accordingly to the contamination variations of the measuring gas, results in a reasonable consumption of the supply liquid at different vapor contents of the measuring gas.
