The coke side smoke outlets 6 and the machine side smoke outlets 8 are arranged at equal intervals along the length direction of the coke oven 1, wherein the machine side smoke outlets 6 are symmetrically arranged in 2 rows along the center line of the carbonization chamber, and the distance between the coke side smoke outlets 6 and the machine side smoke outlets 8 is an integral multiple of the distance between the carbonization chambers.
In the ventilation system of the integrally-closed greenhouse of the coke oven, both the side elevation air inlet 4 and the coke side elevation air inlet 3 adopt a natural ventilation mode. But the heights of the two are different mainly due to the following considerations:
1) In the coke discharging process, the waste heat and smoke dust emitted from the coke tank flow upwards mainly under the action of thermal buoyancy, so that the coke side elevation air inlet 3 is arranged according to the height consistent with the elevation of the upper opening of the coke tank. The elevation of the top of the coke side elevation air inlet 3 is the same as the elevation of the upper opening of the coke tank, so that the overall ventilation effect of the coke oven greenhouse 2 can be ensured, and meanwhile, the harmful substances emitted in the coke tank can not diffuse outside the coke oven greenhouse 2; in addition, as the position of the Jiao Cejin air inlet 3 is basically consistent with the elevation of the coke side operation table, the fresh air introduced from the air inlet 3 on the coke side elevation can purify the working environment of the coke side operation table;

The smoke dust generated at the parts flows upwards under the action of the thermal buoyancy and the horizontal distance between the side furnace column and the outer vertical surface of the coke oven greenhouse 2 is about 40 meters, so that the smoke dust cannot escape outside the coke oven greenhouse 2. Therefore, the height design of the air inlet 4 of the side elevation is consistent with the elevation of the top of the carbonization chamber of the coke oven, so that the waste heat and smoke dust emitted by the coke oven can be effectively trapped, and the trapped smoke dust is sent to a corresponding dust-removing ground station for purification treatment through the side smoke exhaust pipeline 9, so that the emission reaching the standard is realized;
The waste heat and smoke dust emitted from the coke tank flow upwards under the action of heat buoyancy on one hand and float upwards under the action of wind pressure of fresh air on the other hand, so that the coke-side smoke exhaust pipeline 7 and the coke-side smoke exhaust port 6 are arranged at the top of the coke-side space I.

The waste heat and smoke dust generated by the coke oven machine side float upwards under the combined action of thermal buoyancy and wind pressure of the machine side elevation air inlet 4, and a machine side smoke exhaust pipeline 9 and a machine side smoke exhaust port 8 are arranged at the machine side of the coke oven greenhouse 2 and the top of a furnace top space II. The machine side smoke exhaust port 8 is arranged on the main span of the coke oven greenhouse 2, right above the furnace top area, and is provided with 2 smoke exhaust main pipelines. Waste heat and smoke dust in the machine side and furnace top space II are sucked into the machine side smoke exhaust pipeline 9 through the machine side smoke exhaust port 8 and then are sent to the corresponding dust removal ground station for smoke purification treatment and then reach the emission standard.
In the invention, although the coke side space I, the machine side space II and the furnace top space II of the coke oven greenhouse 2 respectively adopt measures of natural air supply and mechanical air exhaust, the furnace top of the coke oven 1 is completely positioned in the coke oven greenhouse 2, and the operating area of the furnace top workers is still positioned in the unfavorable area of airflow vortex. Thus, in order to ensure the working environment of the operating area of the top workers, 2 groups of fresh air pipelines are arranged, wherein
1) A machine side fresh air pipeline 12 is arranged at the upper part of a machine side gas collecting pipe operating platform of the coke oven 1, a plurality of high-speed nozzles 13 are arranged on the machine side fresh air pipeline 12, the high-speed nozzles 13 are positioned at gaps among all ascending pipes, and jet flows to a furnace top area through the high-speed nozzles 13 to convey fresh air, so that the environment of a furnace top working area is improved, and the concentration of harmful substances is reduced.
2) The top of a main pipe of a coke side coal-charging interface valve of the coke oven 1 is provided with a coke side fresh air pipeline 10, the coke side fresh air pipeline 10 is provided with a plurality of air supply pipelines 11, the air supply pipelines 11 are positioned at gaps among the coal-charging interface valves, the air supply pipelines 11 supply fresh air to a furnace top area, and in order to strengthen air disturbance, a pulse valve is adopted to control the air supply sequence, so that the range of the fresh air is ensured, and the environment of a coke oven top worker operation area is further improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
