    Arrangement for sucking-off gases, creating by means of water supplied to an annular nozzle surrounding the outlet of a gas conduit and forming a first hydraulic pump with a vortex, thereby mixing the gas and water thoroughly and sucking off the mixture by a second annular water nozzle into an ejector or second pump extending into a diffuser which terminates below the level of water in a vessel, where separation of the gas and water takes place.

    专利说明:

    The invention relates to a plant for sucking gases used to suck air from a steam turbine condenser.
    A known gas-suction installation containing an air nozzle, a pipe and an ejector (ed. St. USSR No. 2,6674, class G 04 G 5/00, 1971).
    The disadvantage of the known gas suction unit is its low efficiency.
    The purpose of the invention is to increase the efficiency of the gassing unit.
    The goal is achieved by the fact that in a gas-suction unit containing an air nozzle, a nozzle and an ejector, an air nozzle is inserted into the nozzle to form a chamber connected to the supply pipe, an annular nozzle and a mixing chamber, and the nozzle is placed inside the ejector to form a chamber connected. feed line, ring-:
    2 nd nozzle and mixing chamber, to the wall of which a diffuser is connected with the bottom end face placed in the tank.
    The drawing shows a gassing unit connected to a steam turbine condenser.
    The gas extraction unit consists of a mixing part 2, connected via a connecting pipe 10 to a steam turbine condenser, and an ejector 3, which is located downstream of the mixing part 2 and introduced by its diffuser 32 into a tank 4. The mixing part 2 consists of an air nozzle 21, connected to the pipeline 10 and placed the output slice in the chamber 230. The ejector 3 has a chamber 310 in the upper part, a mixing chamber 330 in the middle part, and its lower part is a diffuser 32. The mixing part 2 connection the ejector 3 is carried out by the size

    The bottom of the nozzle 22 in the chamber 310 of the ejector.
    In the upper part of the nozzle 22, a water chamber 210 is formed, equipped with a nozzle 20 of the feeding conduit 5. In the upper part of the ejector 3 there is a chamber 310 equipped with a feeding nozzle 30, which is connected to the lower branch of the feeding conduit 5. The air nozzle 21 is placed in the water chamber 210 concentrically with the formation between its surface and the inner surface of the water chamber 210 of the annular gap, which is an annular nozzle 220. Both the annular nozzle 220 and the air nozzle 21 are located in the upper part of the mixing chamber 230. The mixing chamber 230 is arranged concentrically in the mixing chamber 330, as a result of which an annular gap is formed between the outer surface of the chamber 230 and the inner surface of the chamber 310, which is an annular nozzle 32p.
    Both the annular nozzle 320 and the mixing chamber 230 are located in the upper part of the mixing chamber 330 of the ejector 3. The diffuser 32 is placed with the lower end in the tank 4.
    The operation of the gas suction unit according to the invention is based on the use of a shock wave to homogenize a mixture of water and air in mixing part 2 and on the effective movement of the resulting mixture under the action of ejector 3 to the level of atmospheric pressure. The air sucked from the steam turbine condenser through the connecting pipe 10 is directed by the air nozzle 21 to the mixing part 2 of the ring nozzle 220. From the ring nozzle 220, the water supplied from the feed pipe 5 to the water chamber 210 flows out at high speed. Under the conditions for the occurrence of a shock wave, which are determined from the ratio of pressure in the water chamber 210 and in the mixing chamber 230, i.e. before and behind the shock wave, and the interaction of the annular water jet, given by the size of the annular nozzle 220 with the wall of the mixing chamber 230 and the amount of air supplied through the air nozzle 21, in the mixing chamber 230, a turbo 5- fold circular vortex occurs and air pressure P with water, coming through the annular nozzle 220, increases to a pressure P m . The phenomenon that occurs in the mixing chamber 230 has a highly dissipating nature and is associated with a significant loss of mechanical energy of water that flows from the annular nozzle 220. Therefore, in the proposed gas-suction unit, the effect of the shock wave is limited to the formation of a homogeneous mixture of water and air and the achievement of an intermediate pressure P m so that 20 was achieved optimum efficiency of the ejector 3. The total efficiency of the installation steps above classical ejector efficiency that significantly removed zhaet consumption of working water. The mixture of water with an air of <25 spirit, fed into the ejector 3 from the mixing chamber 230, in the mixing chamber 330 of the ejector 3 is accelerated.
    In the mixing chamber 330 is obtained
    30 further further homogenize the initial air mixture with water flowing from the ejector ring nozzle 320 3. The resulting mixture with increased kinetic energy is led35 into the diffuser 32 through the lower part of the mixing chamber 330. As a result of performing geometric diffuser 32 the kinetic energy of the mixture is gradually transformed into a static davle4θ of which, together with the relative hydrostatic pressure ensures profluvium mixture of air and water through the lower portion of the diffuser 32 to the level of water in the tank 4. In the water tank ob4 5 Birmingham 4 venting occurs from the water / air mixture supplied through the diffuser 32, and the air is freely removed from the tank 4 to the atmosphere.
    50 Thus, the invention may be used not only for the steam turbine condenser, but wherever it is necessary to remove non-condensable gases while improving their 'davle55 Nia ·
