Description

[0002] The split slag lock valve is often used in water-coal slurry, multi-component slurry and dry coal powder fluidized bed pressurized gasification systems for coal gasification liquid slag discharge, and participates in the gasification furnace slag program control.

[0003] For example, a split slag lock valve with the authorization announcement number "CN219639506U" has a second step surface set as an annular corrugated surface, a sealing gasket is set between the valve stem seat and the valve body, and the contact surface between the valve stem seat and the sealing gasket is set as an annular corrugated surface, which greatly improves the sealing effect, and the first valve stem positioning ring and the second valve stem positioning ring enable the upper valve stem and the lower valve stem to be on the same axis, avoiding rotational deviation, improving rotation stability, and not easy to lock, avoiding leakage problems caused by lateral wear due to deviation, and reducing the risk of leakage at the valve stem seat. However, in the use of the split slag lock valve, since there are control structures on both sides above the split slag lock valve, the overall weight of the split slag lock valve is greater than that of different valve bodies. Then, after the split slag lock valve is connected to the pipeline, downward pressure will be generated on the pipeline. In addition, the split slag lock valve has no support, and long-term use will cause deformation of the connecting pipeline and damage to the connection of the split slag lock valve, increasing the maintenance cost of the split slag lock valve and affecting the normal use of the split slag lock valve.

[0026] Working principle:

[0027] Working of split slag lock valve:

[0028] Slag collection: The slag at the bottom of the quenching chamber and a small amount of unburned carbon residue are collected in the lock bucket through the lock bucket inlet valve. In order to facilitate the collection of slag, there is a pipeline on the top of the lock bucket. The black water on the top of the lock bucket is pressurized and circulated back to the washing and cooling chamber of the gasifier through the lock bucket circulation pump as the lock bucket circulation water, so that the black water in the washing and cooling chamber will bring down the slag in the process of flowing downward.

[0029] Lock bucket pressure relief: After the slag collection is completed, the lock bucket inlet valve is closed, and then the lock bucket pressure relief valve is opened to relieve pressure. When the lock bucket pressure indication is less than (0.18MPa), the lock bucket pressure relief valve is closed, and then the lock bucket flushing valve is opened to flush the pressure relief pipeline, and then closed.

[0030] Slag discharge: The lock bucket slag flushing valve is opened so that the lock bucket can be flushed during slag discharge, and the slag in the lock bucket is flushed into the slag pool. The lock bucket outlet valve is opened and the lock bucket discharges slag. After slag discharge, the lock bucket outlet valve is closed and the lock bucket flushing valve is closed.

[0031] Pressurization: After the slag discharge is completed, the lock bucket pressure valve is opened to pressurize the lock bucket to the normal working pressure. After the pressure is charged, the pressure valve is closed and the lock bucket inlet valve is opened.

[0032] Installation support for split slag lock valve:

[0033] The front and rear ends of the split slag lock valve 1 are respectively fixed with the flange 4 and the flange of the external pipeline, and then the first screw 201 on the right side is rotated downward through the straight plate 6. The rotating first screw 201 rotates the groove wheel 206 below, and the rotating groove wheel 206 cooperates with the belt 207 to rotate the groove wheel 206 on the left side, thereby realizing the two first screws 201 rotating downward at the same time, and the rotating first screw 201 moves the square plate 202 downward, and the moving square plate 202 makes the vertical plate 203 move downward on the inner wall of the shell 5, and the moving vertical plate 203 cooperates with the horizontal plate 204 to move the bottom plate 205 downward until the bottom of the bottom plate 205 is tightly pressed against the contact surface, thereby completing the support of the split slag lock valve 1.

[0034] Wire placement of split slag lock valve:

[0035] After the installation of the split slag lock valve 1 is completed, the wire is plugged into the interface of the split slag lock valve 1, and then the handle 304 is used to rotate the second screw 303 upward through the pressure plate 302, so that the bottom of the outer wall of the second screw 303 is separated from the support plate 8, and then the pressure plate 302 is rotated upward through the inner side of the vertical plate 301 to separate the pressure plate 302 from the round rod 9, and then the excessively long wire is wrapped around the outer wall of the round rod 9, and then the pressure plate 302 is rotated downward to make the bottom of the pressure plate 302 press against the top of the round rod 9, and then the handle 304 is used to rotate the second screw 303 downward through the pressure plate 302 to make the bottom of the outer wall of the second screw 303 threadedly connected to the top of the support plate 8, thereby completing the storage of the wire.

[0036] Embodiment 2:

[0037] See also Figure 1-6 In this embodiment, a split slag lock valve further includes a bent rod 10, the bottom of the bent rod 10 is fixedly connected to the top of the first screw rod 201 on the right side.

[0038] Working principle:

[0039] When rotating the first screw rod 201 , the user can hold the curved rod 10 with his hand to exert force, thereby rotating the first screw rod 201 , and the curved rod 10 facilitates the operation of the supporting structure 2 as a whole.
