Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of efficient submerged combustion gasifier, including gas mixer chamber 11, combustion chamber 12, surge chamber 2, pond 3, chimney
32,
Air pipeline 13 and gas pipeline 14 are provided with above the gas mixer chamber 11, combustion chamber 12 is located at gas mixing
The lower section of room 11, combustion chamber 12 are connected to by the first flue gas transmission pipeline 21 with surge chamber 2, the first flue gas transmission pipeline 21
On be provided with the first pump blower 22, surge chamber 2 is connected to by the second flue gas transmission pipeline 25 with distribution lines 41, the second flue gas biography
It is provided with flow control valve 23 and the second pump blower 24 on defeated pipeline 25, connects several outlet pipes on the distribution lines 41
42, several ventholes 43 are opened up on outlet pipe 42,
The surge chamber 2, distribution lines 41, outlet pipe 42 are set in pond 3, and chimney 32 is set to the upper of pond 3
Side,
The arrival end of natural-gas transfer pipeline 4 and outlet end are respectively positioned on outside pond 3, and middle section is located in pond 3 and is in
Coil shape, is distributed in several levels along the vertical direction, and the outlet pipe 42 is located at natural-gas transfer pipeline 4 and is located at pond
The middle position of upper layer and lower layer coil pipe beam inside 3.
As shown in Figure 1, air and combustion gas pass through air pipeline 13 respectively and gas pipeline 14 enters in gas mixer chamber 11
After being sufficiently mixed, enter burning generation high-temperature flue gas in combustion chamber 12 by lighting, passes through the first cigarette by the first pump blower 22
Gas transmission pipeline 21 is pumped into surge chamber 2, then it is lower after flow into distribution lines 41, into outlet pipe 42 after through 43 row of venthole
Out, in pond 3 water and natural-gas transfer pipeline 4 heat.
Gas burns in combustion chamber 12, and due to the severity of burning, the speed of the high-temperature flue gas of generation has one
Fixed fluctuation and impact, in addition, the high-temperature flue gas for generation of burning must be discharged in time in order to make the abundant of burning, it is combustion gas
