The scheme provides a coal industry slag water treatment facilities of gas-liquid separation, including exhaust line 4, horizontal extension's black water pipeline 7, connect in the flash distillation angle valve 8 of the exit end of black water pipeline 7, set up three-way pipe 1 on the black water pipeline 7, the orientation of the bypass interface of three-way pipe 1 upwards and communicate in the entry end of exhaust line 4. The exhaust line 4 may employ thickened carbon steel pipes, such as DN200, CL150 thickened carbon steel pipes.
The black water is conveyed to a flash evaporation angle valve 8 connected with the outlet end of the black water pipeline 7, meanwhile, a three-way pipe 1 is arranged on the black water pipeline 7, the three-way pipe 1 is provided with an inlet and an outlet, the directions of the inlet and the outlet are on the same straight line and are respectively connected with the black water pipeline 7, and in addition, a bypass interface of the three-way pipe 1 faces upwards and is communicated with the inlet end of the exhaust pipeline 4. The non-condensable gas in the fluid in the black water pipeline 7 tends to flow upwards more, so that at least part of the non-condensable gas in the black water can flow upwards into the exhaust pipeline 4 through the bypass interface of the tee pipe 1, thereby realizing at least partial gas-liquid separation with the black water in the black water pipeline, reducing the gas entering the flash angle valve 8, and reducing the impact of the gas on the flash angle valve 8, so as to reduce the vibration caused by the diagonal valve and reduce the loss to the valve core. The tee 1 can adopt DN350 and CL150 to thicken a carbon steel tee.
The gas-liquid separation coal chemical industry slag water treatment device also comprises a flash evaporation cylinder 9 connected to the lower end of the flash evaporation angle valve 8. As shown in fig. 1, the black water in the black water line 7 flows into the flash drum 9 through the flash angle valve 8 and is collected at the bottom of the flash drum 9.
Further, the outlet end of the exhaust line 4 is connected to the bottom of the flash drum 9. The outlet end of the exhaust pipeline 4 is connected to the bottom of the flash evaporation barrel 9, so that noncondensable gas in the black water pipeline 7 is directly conveyed to the bottom of the flash evaporation barrel 9 through the exhaust pipeline 4 without passing through the flash evaporation angle valve 8, gas-liquid separation is realized, vibration of the flash evaporation angle valve 8 is reduced, and the service life of the angle valve is prolonged. And, because the bottom of the flash evaporation barrel 9 gathers and has black water, the black water can play the cushioning effect, reduces the impact that noncondensable gas caused to flash evaporation barrel 9, reduces barrel striking sound and noncondensable gas to the washing of barrel, avoids the barrel to take place to leak.
Optionally, the gas-liquid separation coal chemical industry slag water treatment device further comprises a control valve 5 which is arranged in the exhaust pipeline 4 and used for adjusting the exhaust gas amount. The exhaust amount of the exhaust line 4 can be regulated through the opening degree of the control valve 5, so that the opening degree of the control valve 5 is ensured to be large enough, and the noncondensable gas in the black water pipeline 7 is discharged into the exhaust line 4 as much as possible, so that the reduction of the angle valve vibration and the elimination of the cylinder striking sound are realized. The control valve 5 can adopt DN200 and CL150 ball valves.
Optionally, the gas-liquid separation coal industry slag water treatment device further comprises an exhaust valve 6 arranged on the exhaust pipeline 4 and positioned downstream of the control valve 5. When the exhaust valve 6 is in a closed state, the exhaust pipeline 4 can be isolated from the flash drum 9; in the working process, the exhaust valve 6 is in a complete opening state so as to avoid the inner leakage caused by the abrasion of the valve core due to the erosion of black water. The exhaust valve 6 can adopt DN200 and CL150 ball valves.
Optionally, the gas-liquid separation coal industry slag water treatment device further comprises a flushing pipeline 3 which is connected with the exhaust pipeline 4 at the upstream side of the control valve 5. The flushing pipeline 3 is used for accessing flushing water, flushing the exhaust pipeline 4 when the pipeline stops working so as to avoid impurity deposition carried in the process of conveying noncondensable gas or blocking the exhaust pipeline 4, and simultaneously, the flushing pipeline is convenient for replacing parts after flushing. The flushing pipeline is provided with a flushing water valve, and DN80 and CL150 ball valves can be adopted.
Further, the exhaust line 4 comprises a first line segment 41 directly connected to the tee 1, the first line segment 41 extending vertically perpendicular to the black water line 7. The first straight line segment 41 is connected to the upwardly facing line connection of the tee 1 and extends upwardly in the same direction as it. The noncondensable gases in the black water tend to flow upward more, and therefore, the upward extension of the first straight line section 41 facilitates the smooth upward flow of the noncondensable gases in the black water line 7 into the exhaust line 4.
Further, the first straight line section 41 is provided with an intake valve 2. The intake valve 2 is closed to isolate the exhaust line 4 from the flash drum 9. For example, when the control valve 5 needs to be replaced, the exhaust valve 6 and the intake valve 2 respectively arranged at the outlet end and the inlet end of the exhaust pipeline 4 can be closed, the exhaust pipeline 4 is isolated from the black water pipeline 7, the flash angle valve 8 and the flash drum 9, flushing water is connected through the flushing pipeline 3, and the exhaust pipeline 4 is flushed and the valve is replaced. In the working process, the air inlet valve 2 is in a complete opening state so as to avoid the inner leakage caused by the abrasion of the valve core due to the erosion of black water. The air inlet valve 2 can be a ball valve, for example, the air inlet valve 2 adopts DN200 and CL150 ball valves, and is connected with the top pipe orifice of the tee pipe 1 through reducing pipes of DN200 and CL150 thickened carbon steel.
Specifically, the exhaust line 4 further includes a second straight line segment 42, a third straight line segment 43, a fourth straight line segment 44, and a fifth straight line segment 45, the second straight line segment 42 is connected to the first straight line segment 41 and is perpendicular to the first straight line segment 41 and the black water line 7, respectively, the third straight line segment 43 is connected to the second straight line segment 42 and extends vertically perpendicular to the second straight line segment 42, the fourth straight line segment 44 is connected vertically to the third straight line segment 43 and extends parallel to the black water line 7, and the fifth straight line segment 45 is connected to the fourth straight line segment 44 and extends parallel to the second straight line segment 42.
Further, the first straight line segment 41, the second straight line segment 42, the third straight line segment 43, the fourth straight line segment 44, and the fifth straight line segment 45 are connected by elbows.
Because of the expansion and contraction effect, the pipeline may have overlarge local stress, causing pipeline tearing and other accidents, and the pipeline is easy to deform or damage due to the action of thermal elongation or temperature stress. Thus, the first, second, third, fourth, and fifth straight line sections 41, 42, 43, 44, 45 of the exhaust line 4 are arranged perpendicular or parallel to the extending direction of the black water line; the sections of the exhaust pipeline 4 are connected through elbows, for example, a 5D elbow can be adopted; as shown in fig. 1, the first straight line section 41, the second straight line section 42 and the third straight line section 43 are combined to form an upward-protruding "n" shaped structure to form a gate-type compensation section, so that the acting force of extension can be counteracted and the stress generated by expansion and contraction of the pipeline can be eliminated.
In summary, the utility model provides a gas-liquid separation coal chemical industry slag water treatment device, which can recover noncondensable gas and realize gas-liquid separation of noncondensable gas, so that vibration and impact caused when black water passes through an angle valve are reduced, the service life of the angle valve is prolonged, and the leakage risk is reduced.
