Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail in combination with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. The technical solutions of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0019] Such as Figure 2-3 As shown in the manhole sleeve of the Lurgi gasifier, the sleeve 3 is a cylindrical barrel, and the inside of the sleeve 3 is filled with a heat insulation layer 4 and a reinforcement layer 5 in sequence from the inside to the outside. The heat insulation layer 4 The reinforcing layer 5 is adjacent to each other and completely fills the inside of th...

Abstract

The invention discloses a Lurgi gasifier manhole inner sleeve, relates to a gasifier manhole sleeve structure and aims at solving the problem that a steel plate at the bottom of the traditional manhole sleeve cracks and falls off. The sleeve is a cylindrical drum; the sleeve is filled with a thermal insulation layer and a reinforcing layer sequentially from inside to outside and the thermal insulation layer and the reinforcing layer are adjacent to each other to thoroughly fill the interior of the sleeve; the reinforcing layer is provided with reinforcing ribs. In the Lurgi gasifier manhole inner sleeve, a welded steel plate arranged at the bottom of a traditional sleeve is removed, the reinforcing ribs are welded to the interior of the sleeve, a high-temperature resistance material is poured for solidification, the high-temperature resistance material is directly contacted to a high-temperature environment, and the running effect is achieved through modification, so that the conditionthat a main furnace grate is clamped as the bottom steel plate drops off is prevented, guarantee is provided to stable running of a gasifier, and the Lurgi gasifier manhole inner sleeve can be popularized and used for gasifiers in a same type.

Description

technical field [0001] The invention relates to a manhole sleeve structure of a gasification furnace, in particular to an inner sleeve of a Lurgi gasification furnace manhole. Background technique [0002] Lurgi gasifier, a pressurized moving bed coal gasification device in which coal and gasification agent are in countercurrent contact. The furnace body adopts a double-layer jacketed shell, and the jacket is cooled by boiler water to generate self-produced medium-pressure steam. The main internal parts of the gasifier: the upper Bossman sleeve, the pagoda-shaped grate for ash discharge. In addition to the furnace body, the components of the gasifier include the coal lock for coal feeding at the upper part, the ash lock for discharging ash at the bottom, and the washing cooler at the outlet of the gasifier. [0003] The manhole is used as the maintenance entrance of the gasifier body. Since there is no cooling jacket at this position, in order to ensure the external temper...
