Claims

This invention relates to the field of fire protection. A device for preventing the ignition of a fuel stream from a well is known, which comprises a cylindrical hollow body with a variable internal cross section, nozzles and a branch pipe forming an annular chamber for the liquefied phlegmatizing composition Cl 3 with the body. The disadvantage of the device is insufficient working efficiency under negative temperatures caused by frost failure. composition. The aim of the invention is to increase the efficiency of the devices. The purpose is to ensure that the device for preventing ignition of the flow of fuel from a well, comprising a cylindrical hollow body with a variable internal cross section, with nozzles and a nozzle, forming with the body an annular chamber for the liquefied reflux composition, has a steam line in the body cavity there is a hollow spring, in the walls of which through holes are made parallel to the longitudinal axis of the device, with one end of the spring plugged and the other communicates with the steam line, the cross section of which exceeds the total cross section of the spring holes. Figure 1 shows the proposed device in the inoperative position when the coils of the spring are in a compressed CONDITION; figure 2 is the same device in the working cavity when the coils of the spring are between the nozzles. A device for preventing ignition of the flow of liquid and gas fuel from a well includes an alternating inner diameter body 1 with channels 2, nozzles 3 installed in these channels, a nozzle that forms an annular chamber 5 for a reflux liquid with the body, a nozzle 6 that forms an additional nozzle with i nozzle an annular steam chamber 7 and a hollow spring 8 mounted inside the body with the possibility of re-evaluating its turns relative to the body. The conduit 9 supplies water or some other phlegmatizing fluid to the chamber 5, and the conduit 10 supplies the steam BI to the chamber 7. The upper end of the spring 8 is plugged and the lower open end enters the chamber 7 for steam and is fixed to it. The spring has through vertical holes 11, which communicate its internal cavity with the cavity of the housing. The device is permanently installed at the wellhead. With normal well wiring through the device, all the necessary work can be done. In the event of an open fountain to prevent its ignition through the pipeline 9 under the pressure exceeding the pressure in the housing 1, steam is supplied. Under the action of the vapor pressure, the coils of the spring expand and assume a working position between the nozzles. Exiting tangentially to the surface of the housing I, from the nozzles 3, the jets of phlegmatizing liquid, mixed with a stream of fuel flowing from the well, are diluted and swirled. 10 pairs supplied through the pipeline. into the chamber 7, and then through the holes II of the half-spring 8 into the cavity of the housing 1, also phlegmatizes the flow of fuel from the well. In the course of the movement, the steam transfers its heat to the phlegmatizing liquid and prevents it from freezing at sub-zero temperatures, thereby increasing the efficiency of preventing the ignition of the fuel stream upon exiting the device. The proposed device will provide safe working conditions for workers at the mouth of an open flowing well at minus ambient temperatures. Apparatus of the Invention A device for preventing the ignition of a fuel stream from a well, comprising a cylindrical hollow body with a variable internal cross section, with nozzles and a branch pipe forming an annular chamber for the liquefied phlegmatizing composition with the body, in order to increase its efficiency, it has a steam line and a hollow spring placed in the body cavity, in the walls of which through holes are made parallel to the longitudinal axis of the device, with one end of the spring plugged and the other with Communication with steam pipe whose section is greater than the total cross section of the spring holes.
