Detailed Description
The first embodiment is as follows: the present embodiment is described with reference to fig. 1 to 2, and the present embodiment includes at least one smoke suction hood main body 1, the smoke suction hood main body 1 is horizontally installed on the upper surface of the graphitization furnace 4, the smoke suction hood further includes at least one smoke suction pipeline 2, one smoke suction pipeline 2 is installed on the upper surface of each smoke suction hood main body 1, the smoke suction hood main body 1 and the smoke suction pipeline 2 are communicated with each other through a plurality of smoke suction holes 3, and a draught fan 5 is disposed on the smoke outlet side of the smoke suction pipeline 2.
The size and the main part number of the flue gas absorption cover 1, the thickness of the flue gas absorption pipeline and the number of the smoke absorption holes 3 can be automatically adjusted according to the size of the Acheson graphitizing furnace.
The outer neck 6 of flue gas absorbing hood links to each other with draught fan 5, and draught fan 5 draws forth harmful gas in Acheson's graphitizing furnace in by flue gas absorption pipeline 2 to carry flue gas aftertreatment system and handle, discharge the gas that reaches the environmental protection requirement after the processing in the atmosphere, realized preventing that poisonous and harmful gas from leaking, the emission of nonhazardous gas makes a very big contribution to human environmental protection.
The second embodiment is as follows: the present embodiment will be described with reference to fig. 1 to 2, and a plurality of smoking holes 3 are provided along the longitudinal direction of the smoke absorbing duct 2.
Other components and connections are the same as those in the first embodiment.
The third concrete implementation mode: in the present embodiment, the sizes of the plurality of smoking holes 3 gradually increase from left to right, which is described with reference to fig. 1 to 2.
Because the suction of the smoke suction hole 3 which is closer to the draught fan 5 is larger, and the suction of the smoke suction hole 3 which is farther from the draught fan 5 is slightly smaller, the size of the smoke suction hole 3 is gradually increased from left to right according to the gas flow, so that the smoke suction amount of each smoke suction hole 3 is ensured to be balanced and consistent, the Acheson graphitization furnace is realized, and the toxic and harmful gas generated in the production process is completely and uniformly absorbed.
Other components and connection relationships are the same as those in the first or second embodiment.
The fourth concrete implementation mode: the present embodiment is described with reference to fig. 1 to 2, and the number of the smoking holes 3 in each of the smoke absorbing ducts 2 of the present embodiment is at least two. Other components and connection relationships are the same as those in the first, second or third embodiment.
The fifth concrete implementation mode: the present embodiment will be described with reference to fig. 1 to 2, and the flue gas absorption duct 2 of the present embodiment is manufactured by welding an iron plate or a steel plate.
Other components and connections are the same as those of the first, second, third or fourth embodiments.
