specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 with figure 2 Describe this embodiment, a slag breaking device for the bottom of a slag gasifier in this embodiment includes a flexible sealing device 1, a lever 2, an operating handle 3, a support rod 4, a telescopic rod 5, a flow regulating valve 6, a water supply Pipe 7, water pump 8, and support rod 4 are installed vertically on the ground. Lever 2 is rotatably connected to the upper part of support rod 4. The head end of lever 2 passes through the furnace body of the gasifier and extends into the lower part of the bottom of the gasifier. Inside the tube, the lever 2 is sealed and connected to the gasifier body through a flexible sealing device 1. The end of the lever 2 is provided with an operating handle 3, and a hollow channel is opened from the head end of the lever 2 to the connecting part between the lever 2 and the support rod 4 for water supply. The pipe 7 is airtightly connected with the hollow passage, t...

specific Embodiment approach 2

[0012] Specific implementation mode two: combination figure 1 with figure 2 Describe this embodiment, the lever 2 of this embodiment includes a horizontal part 2-1 and a bending part 2-2, the horizontal part 2-1 is rotatably connected with the lever 2, the bending part 2-2 and the horizontal part 2-1 The left ends are joined and made into one piece. In this way, the bending part 2-2 is provided to facilitate the lever to be inserted into the furnace body, so as to realize the crushing of the slag in the furnace body. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Specific implementation mode three: combination figure 1 with figure 2 To illustrate this embodiment, the bending part 2-2 of this embodiment includes a horizontal rod 2-2-1, a first vertical rod 2-2-2 and a second vertical rod 2-2-3, and the first vertical rod 2-2-3. A vertical rod 2-2-2 and a second vertical rod 2-2-3 are relatively vertically arranged, and the first vertical rod 2-2-2 and the second vertical rod 2-2- 3 are connected by horizontal rods. Such setting is convenient to adapt to the requirements of the downcomer structure of the furnace body, and at the same time, it is convenient to adjust the movement direction of the first vertical rod 2-2-2, so that the cooling water output by the first vertical rod 2-2-2 can be poured On the slag, and after the slag is broken, it can also provide enough falling space for the broken slag. Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention discloses a slag crushing device for the bottom of a slag gasifier, relates to a slag crushing device and aims to solve the problems of unsmooth slagging of a gasifier and influence on normal running of the gasifier caused by high slag blockage rate of a bottom tap of the gasifier in the prior art. A lever (2) is connected with the upper part of a support rod (4) in a rotating manner, wherein the front end of the lever (2) penetrates through a body of the gasifier, and extends into a downcomer at the bottom of the gasifier; the lever (2) is connected with the body of the gasifier through a flexible sealing device (1) in a sealing manner; an operating handle (3) is arranged at the tail end of the lever (2); a hollow passage is formed from the front end of the lever (2) to a connected part of the lever (2) and the support rod (4); a water supply pipe (7) is connected with the hollow passage in the sealing manner; a telescopic rod (5) and a low regulation valve (6) are arranged on the upper part of the water supply pipe (7); the tail end of the water supply pipe (7) is connected with a water pump (8). The slag crushing device is applied to slag crushing of the bottom tap of the gasifier.

Description

technical field [0001] The invention relates to a slag breaking device, in particular to a slag breaking device used at the bottom of a slag gasifier. Background technique [0002] Coal gasification technology is an efficient and clean clean coal technology. The current coal gasification technology is mainly divided into four categories: moving bed gasification, fluidized bed gasification, entrained flow gasification and molten bed gasification. Among them, entrained bed gasification technology has become the main development direction of coal gasification technology due to its advantages of high gasification intensity, large production capacity and high carbon conversion rate. Entrained bed gasification has two main features. One is the high operating temperature, about 1300-1600 ° C. The ash and slag formed in the furnace is liquid, and the slag discharge method is liquid slag discharge; "Technology to protect the furnace wall and reduce heat loss. Slagging accidents of...
