The gasifier is a vertical cylinder lined with refractory bricks. The quenching ring is a quenching device in the downcomer of the water-coal slurry pressurized gasifier. It mainly forms a water film on the inner wall of the downcomer that flows down with the synthesis gas, isolating the high-temperature synthesis gas from direct contact with the downcomer, and protecting the downcomer from deformation caused by high temperature.

[0003] According to a gasification furnace quenching ring with application number CN202122791533.4, this solution solves the problem of how to separate the connecting rod from the guide groove by pulling the connecting ring upward, thereby separating the slider from the liquid inlet pipe, making it easier to disassemble and replace the filter.

[0004] However, the following problems still exist in actual use:

[0005] (1) The existing equipment cannot be effectively and stably installed on the gasifier during use, which makes it unstable as a whole during use, thereby reducing the corresponding protection effect and being unfavorable for actual use.

[0006] (2) The existing equipment has problems during use, such as the poor sealing of its installation location, which results in poor performance. Utility Model Content

Through this technical solution, in response to the shortcomings of the existing technology, the wedge principle is utilized to respectively provide conical blocks and conical grooves on the clamping block and the cross clamping block. Under the clamping of the clamping block, the gasifier and the quenching ring body can be tightly and quickly docked, and the stability and sealing effect are greatly improved.

[0008] The cam is secured to the upper edge of the cam body with a plurality of slots therein and a plurality of slots therein, each of which is secured to a plurality of opposite ends of the cam body by a plurality of locks.

[0009] As a further technical solution, it also includes a tapered block and a tapered groove, wherein the tapered block is inclined upwardly arranged in the inner concave surface of the clamping block, and the tapered groove is inclined upwardly arranged in the two ends of the cross clamping block in the same direction as the rectangular groove.

[0010] As a further technical solution, a rotary cap is also included, which is arranged on one end of the bidirectional threaded rod extending out of the quenching ring body.

[0011] As a further technical solution, a metal sealing gasket is also included. The upper surface of the metal sealing gasket is fixed to the lower surface of the cross block, and the lower surface of the metal sealing gasket is fixed to the gasifier at the corresponding position.

[0012] As a further technical solution, a sealing ring is further included, which is sleeved on the outer side of the connecting ring on the gasifier.

[0013] The beneficial effects of adopting the above technical solution are: a quenching ring docking device for a water-coal slurry pressurized gasification furnace. Through this technical solution, the wedge principle is utilized to respectively provide conical blocks and conical grooves on the clamping block and the cross clamping block. Under the clamping of the clamping block, the gasifier and the quenching ring body are tightly and quickly docked. At the same time, the quenching ring body is tightly pressed against the metal sealing gasket of the gasifier, which greatly improves the stability and sealing effect.
