Abstract
The utility model particularly relates to a sleeve structure of an inlet and outlet of a gasification furnace; comprises a gasification furnace shell, a forged pipe, an inlet and outlet connecting pipe and a sleeve; one end of the forged pipe is embedded into the shell of the gasification furnace, and the forged pipe and the shell are connected into a whole; the sleeve is sleeved at the fixed position of the outer wall of the inlet and outlet connecting pipe, the inner wall of one end of the sleeve is welded with the outer wall of the inlet and outlet connecting pipe, and the other end of the sleeve is in a freely telescopic state; the outer wall of one end of the sleeve is welded with the inner wall of the forged pipe; the inlet and outlet connecting pipes of the gasification furnace adopt a sleeve structure, so that the influences of local undercut and insufficient strength reduction caused by the fact that the connecting pipes are locally welded in the operation process of high-temperature and high-pressure equipment are solved, and the stress condition of the connecting pipes is buffered by the sleeve structure design; the sleeve structure plays a role in protecting the inlet and outlet connecting pipes, and meets the requirement of long-period safe and stable operation of equipment.
Description
Technical Field
The utility model relates to a coal gasification furnace core internals and stove outer covering exit structure such as modern coal chemical industry, petrochemical industry enterprise, concretely relates to gasifier business turn over mouth sleeve structure.
Background
When water-cooled walls of core internals and inlet and outlet connecting pipes of a radiation waste boiler of the existing gasification furnace are led out from a shell forging pipe, the inlet and outlet connecting pipes are directly welded with the end part of the forging pipe, and the structure has the following defects: 1. when the inlet and outlet connecting pipes are welded with the end parts of the forged pipes, the surface undercuts of the inlet and outlet connecting pipes and the stress generated in the assembly process are easily caused; 2. the inlet and outlet connecting pipes are directly welded with the end parts, so that the fracture phenomenon at the connecting part can be caused under the conditions of local bending moment, torque and vibration in the operation process of the equipment, and the safe operation of the system is influenced.
Disclosure of Invention
The utility model provides a sleeve structure for the inlet and outlet of a gasification furnace, which solves the technical problems that the local part of the inlet and outlet connecting pipe of the existing gasification furnace adopts a direct welding method to cause local undercut and strength reduction.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: a sleeve structure for an inlet and an outlet of a gasification furnace comprises a gasification furnace shell, a forged pipe, an inlet and outlet connecting pipe and a sleeve; one end of the forged pipe is embedded into the shell of the gasification furnace, and the forged pipe and the shell are connected into a whole; the sleeve is sleeved at the fixed position of the outer wall of the inlet and outlet connecting pipe, the inner wall of one end of the sleeve is welded with the outer wall of the inlet and outlet connecting pipe, and the other end of the sleeve is in a freely telescopic state; the outer wall of one end of the sleeve is welded with the inner wall of the forged pipe.
The working principle is as follows: when the inlet and outlet connecting pipes are assembled, the sleeve is welded with the forged pipe, the sleeve can play a role in protection, and the phenomenon that the local strength of the connecting pipes is reduced due to undercut caused by direct welding of the inlet and outlet connecting pipes and the forged pipe is avoided; the influence of vibration, bending moment and torque force on the connecting pipe in the operation process of equipment is avoided, the phenomenon of fracture at the connecting part is possibly caused, and the free expansion process of the connecting pipe under high temperature and high pressure is slowed down. The inlet and outlet connecting pipes of the gasification furnace adopt a sleeve structure, so that the influence of the local direct welding defect of the connecting pipes in the operation process of high-temperature and high-pressure equipment is overcome, and the stress condition of the connecting pipes is buffered; the sleeve plays a role in protecting the connecting pipe, and long-period operation of the equipment is met.
Compared with the prior art the utility model discloses following beneficial effect has:
the inlet and outlet connecting pipes of the gasification furnace adopt a sleeve structure, so that the influences of local undercut and insufficient strength reduction caused by the fact that the connecting pipes are locally welded in the operation process of high-temperature and high-pressure equipment are solved, and the stress condition of the connecting pipes is buffered by the sleeve structure design; the sleeve structure plays a role in protecting the inlet and outlet connecting pipes, and meets the requirement of long-period safe and stable operation of equipment.
Drawings
Fig. 1 is a schematic view of the structure of the inlet and outlet sleeve of the gasification furnace of the present invention.
The figures are labeled as follows:
1-gasifier shell, 2-forged tube, 3-inlet and outlet connecting tube and 4-sleeve.
Detailed Description
The present invention will be further described with reference to the following specific examples.
Examples
As shown in fig. 1, an inlet and outlet sleeve structure of a gasification furnace comprises a gasification furnace shell 1, a forged pipe 2, an inlet and outlet connecting pipe 3 and a sleeve 4; one end of the forged pipe 2 is embedded into the gasification furnace shell 1, and the forged pipe and the gasification furnace shell are connected into a whole; the sleeve 4 is sleeved at the fixed position of the outer wall of the inlet and outlet connecting pipe 3, the inner wall of one end of the sleeve 4 is welded with the outer wall of the inlet and outlet connecting pipe 3, and the other end of the sleeve is in a freely telescopic state; the outer wall of one end of the sleeve 4 is welded to the inner wall of the forged pipe 2. The sleeve 4 can play a role in protection, and the phenomenon that the local strength of the connecting pipe is reduced due to undercut caused by direct welding of the inlet/outlet connecting pipe 3 and the forged pipe 2 is avoided; the influence of vibration, bending moment and torque force on the connecting pipe in the operation process of equipment is avoided, the phenomenon of fracture at the connecting part is possibly caused, and the free expansion process of the connecting pipe under high temperature and high pressure is slowed down.
Further, the end of one end of the forged pipe 2 embedded in the gasification furnace shell 1 is flush with the inner wall of the gasification furnace shell 1.
The device of the utility model has reasonable structural design, is convenient for processing and welding, and the inlet and outlet connecting pipes 3 of the gasification furnace adopt the structure of the sleeve 4, thereby solving the influence of the local direct welding defect of the connecting pipe in the operation process of high-temperature and high-pressure equipment and buffering the stress condition of the connecting pipe; the sleeve 4 plays a role in protecting the connecting pipe and meets the requirement of long-period operation of equipment.
