Detailed Description
As shown in fig. 1-4, a black water pipeline leakage-proof structure comprises a connecting pipe 1 in a T shape, the connecting pipeline 1 comprises a liquid inlet pipe 11 and a liquid outlet pipe 12 which are connected with each other, a leakage-proof part extends along the axial direction of the connecting part of the liquid inlet pipe 11 and the liquid outlet pipe 12, the liquid inlet of the liquid inlet pipe 11 is connected with the gasification furnace through an adjusting valve 2, the liquid outlet of the liquid outlet pipe 12 is connected with a high-pressure flash tank 3, the leakage-proof part is provided with a blind head 4, so that the solid black water entering the liquid inlet pipe 11 flows to the liquid outlet end of the liquid inlet pipe 11 firstly under the action of the original impulsive force, after meeting the blind head 4, the solid black water is blocked by the blind head 4, and then flows to the liquid outlet pipe 12 and enters the high-pressure flash tank 3 from the liquid outlet pipe 12, namely, the liquid outlet end of the liquid inlet pipe 11 can play a role of buffering, and the situation that the joint of the liquid inlet pipe 11 and the liquid outlet pipe 12 is leaked due to direct flushing of solid black water is prevented. The liquid inlet end of the liquid inlet pipe 11 is provided with the buffer plate 13, so that the flow velocity of solid black water entering the liquid inlet pipe 11 can be reduced, and the buffer effect is achieved.
Specifically, as shown in fig. 1, the buffer plates 13 are sequentially arranged in an inclined manner along the liquid inlet direction of the liquid inlet pipe 11, so as to gradually reduce the flow velocity of the black water. The included angle between the liquid inlet direction of the liquid inlet pipe 11 and the pipe wall of the liquid inlet pipe 11 of the buffer plate 13 is alpha, and the angle of alpha is 100-120 degrees.
