Examples

As shown in fig. 1, the present embodiment provides a device for collecting combustible gas in steam, which includes a conduit 1, a condensed water tank 2, a separation bottle 5, a first exhaust pipe 4 and a second exhaust pipe 8; one end of the conduit 1 is used for being connected with a discharge port of the tower kettle; the condensed water tank 2 is communicated with the other end of the guide pipe 1; the separation bottle 5 is internally stored with water, and can separate out combustible gas which is not contained in the water under the action of the water so as to be convenient to collect; one end of the first exhaust pipe 4 is communicated with the guide pipe 1, and the other end of the first exhaust pipe 4 extends into the bottom of the separation bottle 5; one end of the second exhaust pipe 8 extends into the lower part of the bottle mouth of the separation bottle 5, and the other end of the second exhaust pipe 8 is connected with a gas collecting mechanism 9.

A first sealing plug 51 is arranged in the bottle mouth of the separation bottle 5, the first exhaust pipe 4 penetrates through the first sealing plug 51 and extends into the bottom of the separation bottle 5, and one end, far away from the gas collection mechanism 9, of the second exhaust pipe 8 penetrates through the first sealing plug 51 and extends into the lower portion of the bottle mouth of the separation bottle 5.

The side wall of the bottom of the separation bottle 5 is provided with a water outlet 6, the water outlet 6 is internally provided with a second sealing plug 52, the second sealing plug 52 is provided with an overflow pipe 7, one end of the overflow pipe 7 penetrates through the second sealing plug 52 and extends into the separation bottle 5, and the other end of the overflow pipe 7 is of an elbow structure.

A horizontally arranged water level warning line 53 is arranged on the body of the separation bottle 5, the height of the water level warning line 53 is equal to the height of the highest point of the overflow pipe 7, and when the liquid in the separation bottle 5 exceeds the height of the water level warning line 53, the liquid is discharged through the overflow pipe 7, so that the height of the liquid in the separation bottle 5 is kept unchanged.
