It is appreciated that question response gas can also enter from the first gas collecting tube 80, basket 70 is reacted subsequently into radial direction, is being catalyzed
React under the action of agent, while produce heat, the heat of generation is absorbed by the unreacted cold air in air cooled lamp 57, by anti-
Gas after answering enters gap 105 by the venthole of radially reaction 70 side wall of basket, finally exports the reaction that is gas-cooled from gas port 104
Device.When question response gas enters from the first gas collecting tube 80, when being exported from gas port 104, radial direction reacts the cylinder of the vent hole structure of basket 70
Body 701 should be arranged on compared with air permeable plate 703 close to the side of outer barrel 10, the cylinder 801 of the first gas collecting tube 80 should be arranged on compared with
Side of the air permeable plate 803 away from the radially cylinder 701 of reaction basket 70, and radially the structure of the venthole of reaction basket 70 is preferably to scheme
The vent hole structure as gathering gas shown in 4, and the structure of the venthole of the first gas collecting tube 80 is preferably the work shown in Fig. 3
For the vent hole structure of gas dispersion, i.e., radially the structure of the venthole of reaction 70 and first gas collecting tube 80 of basket is exchanged.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Cannot therefore it be construed as limiting the scope of the patent.It should be pointed out that come for those of ordinary skill in the art
