Description

Tamping coke oven machine side furnace door and furnace top smoke trapping device and method
Technical Field
The invention relates to the technical field of coke oven smoke purification, in particular to a tamping coke oven machine side furnace door and a furnace top smoke trapping device and method.
Background
When the tamping coke oven is filled with coal, the smoke dust emitted from the oven top is trapped and purified in two main modes, one is that the smoke dust is trapped by adopting an oven top smoke elimination car or an oven top smoke guide car and then is treated on site by a dust remover and a fan; the other is that the crossing pipe of the smoke guiding vehicle is adopted to guide the coal-charging smoke dust into the adjacent carbonization chambers, and the cross pipe is matched with high-pressure ammonia water injection to guide part of the smoke dust into the coke oven gas collecting pipe. The method can only collect and treat the smoke dust at the furnace top, but has no corresponding treatment means for the escaping smoke dust of the side furnace door, and the smoke dust discharged to the atmosphere from the upper part of the side furnace door still causes serious pollution when the coke oven is charged with coal.
The Chinese patent with the application number of 200710158812.9 discloses a method and a device for trapping furnace top smoke and side furnace door of a tamping coke oven, which can realize the trapping of the furnace top smoke and side smoke, wherein the trapped furnace top smoke is led into a dust-removing ground station through a smoke butt joint duct, a double-interface flap valve and a dust-removing main pipe after being combusted in a vehicle-mounted combustion chamber; the smoke dust emitted by the machine side furnace door comes from the furnace door of the carbonization chamber which is charging coal, and is led into the interface valve by adopting the suction hood and the connecting pipe, and is led into the dust-removing ground station after being converged with the smoke dust of the furnace top.
However, in practical application, because the smoke guide car is longer, one end of the smoke guide car collects furnace top smoke dust through the lifting sleeve, the smoke dust burnt in the combustion chamber reaches the other end of the smoke guide car through the smoke dust guide pipe, and the condition that the furnace top smoke dust is in horizontal dislocation with the side furnace door of the carbonization chamber for emitting the smoke dust when the coal is charged to the outlet of the dust removal dry pipe can not be realized, and the requirements of simultaneously guiding the furnace top smoke dust on the smoke guide car and the side smoke dust from the side furnace door of the machine side furnace can not be met.
