Description

The invention relates to gas burner devices and may find application in the combustion of associated petroleum gases.

Known flare pipe, which contains a barrel with lower and upper inlet openings, a lattice of round or rectangular cross section with partitions of different heights with the formation of a conical surface, a multi-nozzle nozzle, the angle formed by the conical surface and normal to the axis of the nozzle is 35-40 ° (patent RF №2062950, publ. 06/27/1996).

Closest to the claimed invention in technical essence is a flare pipe including a flare barrel, a flare barrel head, a candle, an electric valve, a running flame device, a support, a gas inlet fitting, a steam inlet fitting, a fuel gas fitting, a condensate outlet fitting (Makarov GV "Labor protection in the chemical industry". M: Chemistry, 1989, p. 304 - prototype).

A common disadvantage of the known flare pipes is the lack of the ability to drain impurities and gas condensate deposited in the blind part of the flare pipes.

The proposed invention solves the problem of removing sedimentary impurities and condensate.

The problem is solved in that in the flare pipe including a support, a housing and a gas inlet fitting, according to the invention, the support is conical, an elliptical bottom is placed at the junction of the support and the housing, equipped with a tube with a valve in the lower part, the housing and the support are equipped with a heater in the form of a coil with the beginning of the coil located below the elliptical bottom, and the end of the coil located above the gas inlet fitting.

SUMMARY OF THE INVENTION

A disadvantage of the known flare pipes is the lack of the ability to drain impurities and gas condensate deposited in the blind part of the flare pipes. When an insufficiently separated gas is supplied to the combustion, impurities and condensate from the gas accumulate in the lower stagnant zone of the housing, which can lead to a stop of gas combustion. The proposed invention solves the problem of eliminating the stagnant zone in the blind part of flare pipes and removing sedimentary impurities and condensate. The problem is solved by the flare pipe shown in the drawing.

The following notation is adopted in the drawing: 1 - housing, 2 - conical support, 3 - gas inlet fitting, 4 - elliptical bottom, 5 - tube, 6 - valve, 7 - coil heater, 8 - coil end, 9 - coil beginning .

A tube 5 with a valve 6 is welded into the elliptical bottom 4. Then, an elliptical bottom 4 with a pipe 5 with valve 6 is welded into the lower part of the housing 1 provided with a gas inlet 3, and a conical support 2 is welded to the housing 1. The elliptical bottom is on the contact of the housing 1 and conical support 2.

The diameter of the tube 5 is selected to ensure the maximum flow of condensate from the housing 1. By means of the valve 6, the flow is regulated, providing, on the one hand, a constant flow of condensate, on the other hand, preventing gas from breaking through the tube 5.

To completely remove condensate and impurities, it is necessary to maximize the mobility of the condensate by heating it.

To heat condensate, a heater 7 is installed in the lower part of the housing 1 so that the upper part of the heater 7 is above the gas inlet fitting 3, and the lower one is below the elliptical bottom 4. For this, the heater is made in the form of a coil with the beginning of a coil 9 located below the elliptical bottom 4, and the end of the coil 8, located above the gas inlet fitting 3. When the flare pipe is operating, the coolant passes through the heater coil 7 from the beginning of the coil 9 to the end of the coil 8.

The coil of the heater 7 relative to the gas inlet 3 is made two shoulders: the upper arm or part of the heater 7 above the gas inlet 3 makes up a third of the length of the heater 7, and the lower shoulder or part of the heater 7 below the gas inlet 3 makes two-thirds of the length of heater 7. As shown studies, it is this arrangement of the heater 7 that provides the best heat distribution in the condensation zone in the lower part of the housing 1 and contributes to the most complete removal of condensate, a complete discharge of the heated the condensate through the tube 5. Placing the beginning of the coil 9 below the elliptical bottom 4, below the junction of the housing 1 and the conical support 2 provides heat accumulation in the upper part of the conical support 2 under the elliptical bottom 4, heating of the elliptical bottom 4 and heating of the condensate by the elliptical bottom 4 itself. The conical part of the conical support 2 contributes to the concentration of heat by the cone of the support 2 on the elliptical bottom 4, which also contributes to the heating of the elliptical bottom 4 and the condensate.

The application of the proposed device will solve the problem of removing sedimentary impurities and condensate from the flare pipe.
