Catalyst device and gas cracking heating system

Abstract

A gas heating pyrolysis system includes an outer sleeve, an inner sleeve located within the outer sleeve, a heat insulation structure, multiple heating rods, coils, and a catalyst device. The outer sleeve has an inlet section, an outlet section, and a base plate located in the outlet section. The catalyst device is located in the outlet section. The catalyst device is detachably located within the inner sleeve and inside the heating rods. The catalyst device includes a housing, a catalyst layer located within the housing, a cover covering the catalyst layer, and a disassembly module covering the outlet section of the housing. This disassembly module is detached from the base plate of the outer sleeve, allowing the catalyst device to be completely removed from the gas heating pyrolysis system for catalyst replacement.

Claims

1. A catalyst device, comprising: a housing having an inlet and an outlet; at least one catalyst layer located within the housing, the catalyst layer having a catalyst; at least one cover member located within the housing and covering one end of the catalyst layer, the cover member having a plurality of pores, each pore having a diameter smaller than a particle size of the catalyst; and a disassembly module connected to the housing and covering the outlet.

2. The catalyst device as claimed in claim 1, wherein the number of catalyst layers is multiple, the catalyst layers including a first catalyst layer, a second catalyst layer and a third catalyst layer arranged sequentially from the inlet to the outlet, and the number of cover members is multiple, respectively covering one end of the first catalyst layer, one end of the second catalyst layer and one end of the third catalyst layer.

3. The catalyst device as claimed in claim 2, wherein the housing includes an outlet region accumulation space located between the third catalyst layer and the outlet portion.

4. The catalyst device as claimed in claim 3, wherein the housing includes a plurality of spaced storage spaces located between the first catalyst layer and the second catalyst layer, and between the second catalyst layer and the third catalyst layer.

5. The catalyst device as claimed in claim 2, wherein the number of the cover members is six, respectively covering two ends of the first catalyst layer, two ends of the second catalyst layer and two ends of the third catalyst layer.

6. The catalyst device as claimed in claim 2, wherein the catalyst layer includes an openable sleeve, the catalyst is disposed within the openable sleeve, and the openable sleeve has two opposing semi-circular tubes.

7. The catalyst device as claimed in claim 1, wherein the disassembly module includes a cover plate, a cover member, and a seal member, the cover member covering the cover plate, and the seal member being located between the cover member and the cover plate.

8. The catalyst device as claimed in claim 7, wherein the disassembly module includes a plurality of fasteners attached to the cover.

9. A gas heating and pyrolysis system, comprising: an outer sleeve having an inlet, an outlet, and a bottom plate located in the outlet; an inner sleeve disposed within the outer sleeve, the inner sleeve having a flow channel communicating between the inlet and the outlet; a heat insulation structure disposed between the outer sleeve and the inner sleeve; a plurality of heating rods arranged in a ring within the inner sleeve; a coil surrounding the outer side of the heating rods, the coil including an inner tube and an outer tube of a double-tube structure, the inner tube and the outer tube of the coil each having a communicating inner circumferential path, the coil having an inlet communicating with the inlet and an outlet communicating with the flow channel; and a catalyst device located in the outlet and disposed within the inner sleeve, the catalyst device comprising: A housing having an inlet and an outlet; at least one catalyst layer located inside the housing, the catalyst layer having a catalyst; at least one cover member located inside the housing and covering one end of the catalyst layer, the cover member having a plurality of pores, each pore having a diameter smaller than a particle size of the catalyst; and a disassembly module connected to the housing and covering the outlet, the disassembly module being detachably connected to the bottom plate of the outer sleeve.
