    • 专利摘要:
    In a heat consumer (2), of which the supply conduit (12) is under a predetermined pressure and of which the return (13) is at a lower pressure, the steam, drawn off from the primary steam circuit in relation to the heat used by the consumer, is cooled down until condensation by drawing off heat by means of a secondary fluid and by maintaining a certain overpressure with respect to the pressure prevailing in the supply conduit (12). This overpressure is reduced to the pressure of the supply conduit (12) by means of a jet pump which allows a drive force to be obtained for the supply conduit (12) and the addition to the supply conduit heated secondary fluid obtained by the cooling of steam. In order to avoid installing an overpressure pump upstream of the jet pump while eliminating superfluous valves and connections, the condensate is accumulated to set the heat consumer temperature and the accumulation of condensate is exclusively set by adjusting the ejection nozzle (10).

    专利说明:

    The invention relates to centralized heat supply systems, and in particular to steam heating systems for buildings with a central heat exchanger
    The purpose of the invention is to simplify regulation and reduce metal consumption.
    The drawing shows a schematic diagram.
    The method is as follows.
    The steam is supplied under excess pressure through a supply steam line, condensed in a heat exchanger by heating the return water returned from the heat consumer. Steam condensate is supplied under overpressure to the working nozzle of the jet pump, and part of the return water after the consumer is supplied to its receiving chamber and the return water, which is not used in the jet pump, is returned to the steam generator. Then, heat consumption is controlled by changing the level of condensate in the heat exchanger by changing the flow area of the nozzle of the jet pump.
    The device comprises a primary steam pipe 1, a heat exchanger 2, a coil 3, a connecting pipe 4, a jet pump 5, a nozzle 6, a consumer supply pipe 7, a consumer return pipe 8, a heat consumer 9, and a condensate return 10, a control valve 11, a level sensor 12, a magnet 13, a pressure sensor 14, a heat-sensitive element 15, a control device 16, an actuator 17, an adjustment needle 18.
    The device operates as follows.
    From the primary steam line 1, steam enters the tubular coils 3 of the heat exchanger 2, where it condenses as a result of heating the reverse water washing the bundle of tubular coils 3. The condensate formed in this case is under pressure in the primary steam line 1 and flows through the pipe 4 to the nozzle 6 of the jet pump 5 Depending on the position of the pump nozzle 6, a different amount of condensate flows through the jet pump, which then passes through the supply pipe 7 to the heat consumer 9. When condensate passes through the jet The fifth pump 5 is suctioned on the return water side after the consumer from the heat exchanger 2 heated by condensing steam. This medium is mixed with condensate entering the jet pump 5 according to the position of the pump nozzle 6, and therefore the heat consumer 9 receives a mixture of condensate with return water after it. Depending on the amount of heat consumed by the heat consumer 9, the temperature of the water in the supply pipe 7, measured by the heat-sensitive element 15, differs from the pre-set temperature and therefore the control device 16, using the actuator 17, restores the set temperature by adjusting the position of the needle 18 in the nozzle 6 of the jet pump. If the temperature exceeds a predetermined temperature, then the needle 18 is set in a position in which more condensate can flow from the heat exchanger 2 compared to the steam in the steam network. At the same time, energy decreases behind the pump nozzle 6 and less return water is pumped out of the heat exchanger 2 to supply heat to the consumer 9. If the temperature measured in the supply pipe 7 is lower than the set temperature, i.e. the heat consumer · 9 takes a large amount of heat, then using the device 16 and the actuator 17 the pump nozzle 6 is controlled so that the flow rate of condensate and return water increases.
    If the condensate level in the coil 3 or in the heat exchanger 2 rises unacceptably high with an extremely small heat removal by the consumer 9, then in this case the level sensor 12 is activated, which opens through a magnet 13 connected to the control valve 11, and the condensate is removed from the pipeline 4 bypassing the jet pump 5 and the heat consumer 9 into the return condensate line 10 of the steam network. The condensate is discharged non-j directly into the return condensate line 10 under the influence of steam pressure on it. In this case, the control valve 11 together with the pressure sensor 14 serve simultaneously to maintain the minimum pressure in the return condensate line 10.
