    The invention relates to a nozzle for continuous separation of a representative sample from a duct-containing gas for its analysis. The nozzle has a pipe, intended to open into the sample-taking space, for continuous separation of the sample from a dust-containing gas and for directing the sample to be analyzed, and a second pipe for feeding water into the mouth of the sample-taking pipe in order to keep it clean and to mix the water with the gas sample. In order to obtain a representative sample and to ensure that the nozzle remains open, at the sample-taking end of the sample-taking pipe there is fitted a sleeve which extends somewhat beyond the pipe and encircles it, the water pipe being connected to the sleeve in order to feed water via the annular clearance between the sleeve and the sample-taking pipe to a point in front of the mouth of the sample-taking pipe, and from the inner wall of the open part of the sleeve, extending beyond the sample-taking end of the sample-taking pipe, there extends a ring-like stop oriented against the water flow, in which case a slit, transverse in relation to the gas flow direction and encircling the sample-taking mouth, is formed between the stop and the end of the pipe.

    This invention relates to a device for taking a representative sample from a gaseous mixture containing a solid impurity, for example dust, for analyzing this sample.
    The purpose of the invention is to increase the representativeness of the sample and to ensure the required flow rate.
    1 shows a sampling nozzle; FIG. 2 shows the node I in FIG. one ; 3 is a nozzle, an embodiment of FIG. 4 is a gas analyzer circuit.
    The sampling nozzle includes a sampling tube 1 with an inlet 2, a channel 3 for supplying fluid to the inlet. The outlet part of the channel 3 is located at a distance from the inlet of the sampling tube 1 with the formation of a slot 4 located across the axis of the inlet of 2. A channel 3 for supplying fluid supplying with a sleeve 5 protruding outward at the end of the sampling tube 1 and coaxially with the formation of a gap between them, communicating with channel 3. The sleeve 5 is made with an inner ring-shaped stop 6. The slot 4 is made of constant width, at each point perpendicular to the axis of the inlet 2 of the tube 1 and is located symmetrically about the axis Khodnev sampling tube orifice. The width of the slit is 0.005-0.1 mm, preferably 0.05 mm, while providing the required flow rate.
    The end of the sampling tube may be provided with a spiral groove in order to provide a spiral stream of water.
    The nozzle for sampling works as follows.
    The gas sample is sucked off with a certain flow rate through the sampling tube 1. The inner surface of the tube is washed with a continuous stream of liquid (water). The water is directed through the channel 3 to the inlet 2 so that it completely passes into the inside of the tube 1 for washing the gas sample and cleaning its inner surface with an exactly dosed amount of liquid.
    Thereafter, the water is directed to the separator 7, where the water-insoluble solid components are separated from the stream of water, which is then sent to the next separator 8,

    where the gases are separated from the flow of water and sucked away. The flow of water is directed to the measuring cell 9. In case of clogging of the inlet 2, sampling is stopped and, due to the termination of the vacuum in the sampling tube 1, the flow of water coming out of the slot 4 goes from the nozzle to the space from which the sample is taken and effectively cleans a mouth 10 of the sampling tube I and an opening 11 formed by an annular abutment 6. Such a short flushing is carried out periodically, whereby the tip of the nozzle is not soiled. When resuming the intake of the sample into the sampling tube 1, the sample will be of high quality, since the flushing stopped both the gas and the flushing liquid in the sampling tube 1.
    Fluid in the nozzle, it is advisable to enter as close as possible to the front. nozzle edge. In the sampling tube 1, a liquid film is formed at the inlet, the impact of gas and the dust inside it starts to dissolve in the liquid. Passing through the nozzle, the flushing fluid, which flows with the gas in the tube 1, forms a plug at fairly regular intervals, and due to this, flushes the tube walls well.
    Sleeve 5 can be installed on. The implementation of the sleeve on the thread allows you to adjust the axial width of the slit.
