Definitions
- the invention relates to a device for gas sampling from a flowing gas through a pipe, in particular from the exhaust gas of a metallurgical furnace vessel, wherein the removal takes place through a suction line by means of a plunging into the gas stream, connected to a sample sucking analysis device flow body whose inlet opening in the flow direction the gas is open,
- a sampling tube is gas-tight through the wall of the flowing gas
- Extraction tube designed as a flow body.
- the aspiration of the gas sample is carried out through an opening in the sampling tube, which in
- Gas flow is located.
- This device has an inner tube with which the extracted gas sample of the
- Analytical device is supplied, wherein at the beginning of this tube, a particulate filter is arranged.
- This innermost tube is surrounded by a second tube, which with the
- the invention has for its object to simplify the device for gas sampling and at the same time to increase their service life.
- This object is achieved according to the invention with a device for gas sampling from a gas flowing through a pipe, in particular from the exhaust gas of a metallurgical furnace vessel, wherein the removal takes place through a suction line by means of a plunging into the gas stream, connected to a sample sucking analysis device flow body whose Inlet opening in the flow direction of the gas is open, which is characterized in that the adjoining the inlet opening region is formed as a flow calming chamber.
- a particle filter is arranged at the rear end of the flow calming chamber, at the rear side of which the suction line for the gas sample is connected.
- the suction line is surrounded by a flushing pipe, with which a flushing medium from the back of the particle filter can be pressed therethrough.
- the flow body has cavities, to which a hot water supply for cooling the flow body are connected.
- the inlet opening can be arranged essentially tangentially opening in the flow body relative to the gas stream flowing past the flow body or also transversely in the flow body relative to the gas stream flowing past the flow body.
- FIGS 1 to 3 schematically show three different embodiments of the flow body according to the invention.
- the flow body is shown schematically, but not the line or the pipe through which the exhaust gas flows coming from the metallurgical vessel Substitute only the surrounding the flow body flow of the exhaust gas is indicated and designated 2.
- the flow body itself is designated 1.
- the flow body has an inlet opening 3, which in the embodiment shown in this figure is arranged transversely or perpendicular to the flowing exhaust gas. It is open in the direction of the flowing exhaust gas.
- a flow calming chamber 4 connects. This serves to achieve at least a first deposition of dust particles contained in the exhaust gas.
- a particle filter 5 is provided at the outlet side of which the suction pipe 6 for the sampling begins.
- the suction pipe is surrounded by a flushing pipe 7 through which a flushing medium can be pressed against the suction of the sample gas from the rear side through the particle filter 5, in order to free it from deposits.
- cavities 8 through which a coolant can flow, wherein the coolant may be, for example, 100 ° C. hot water.
- the embodiment of the flow body 1 shown in FIG. 2 deviates so far from the embodiment according to FIG. 1, as here a back-side of the particle filter 5, a mechanical cleaning mechanism 9 is shown, in the manner of a pusher.
- the design of the flow body according to FIG. 3 deviates so far from the two other embodiments shown in FIGS. 1 and 2, as here the inlet opening 3 is not arranged transversely to the flow direction of the exhaust gas in the flow body, but is opened in the lateral wall, that is, it is essentially tangentially open-based on the gas stream flowing past the flow body 1.
