Embodiment 2
As shown in figure 8, the mixer wash mill of the present embodiment dust-laden synthesis gas includes 3 groups of ash water lines, actual fabrication
When, according to the different flexible settings of gasifier operation load.
The ash water lines are same as Example 1, the other parts of the mixer wash mill of the present embodiment dust-laden synthesis gas
It is same as Example 1.
Embodiment 3
As shown in figure 9, grey water lines further include the second buck in the mixer wash mill of the present embodiment dust-laden synthesis gas
Endless tube 25 and gray water outlet line 26, the gray water outlet line 26 are opened on the tube wall of syngas tube 1, the second buck endless tube 25 with
The gray water outlet line 26 is connected to and is circumferentially arranged along the syngas tube inner wall, and one end of grey water pipe 23 and the first buck endless tube 22 connect
Logical, the other end is connected to the second buck endless tube 25.The diameter of the second buck endless tube 25 be 20mm, the gray water outlet line 26 it is straight
Diameter is 45mm.
The other parts of the mixer wash mill of the present embodiment dust-laden synthesis gas are same as Example 1.
The working principle of the mixer wash mill of the dust-laden synthesis gas of the present embodiment is as follows: when buck solid content is very high,
Particle is easily settled in buck, when low-load operation, buck can be made to keep one in grey water lines using circulation line
The flowing of constant current speed, effectively avoids the fouling blockage of grey water lines.
