Specific embodiment
Unless otherwise indicated, the scientific and technical terminology of the utility model is that the conventional of this field understands.
It is the specific embodiment of the utility model below, to be further explained explanation to the utility model.
Embodiment 1:
The semi-coke furnace roof raw coke oven gas recycle device of the utility model, raw coke oven gas are administered in a manner of recycling:
With reference to Fig. 1, device includes the collection ballute 11, diffuse channel 10 and recovery channel 17 being located in coal bunker 1, collects ballute
11 are located in coal bunker 1, and diffuse channel 10 is mounted on 11 top of collection ballute, and one end is connected to collection ballute 11, and the other end sets top cover
14, top cover 14 communicates after opening with atmosphere；17 one end of recovery channel is connected to collection ballute 11, and the other end is raw coke oven gas delivery outlet,
The raw coke oven gas delivery outlet refers to the system that can utilize recycled raw coke oven gas using system for connecting the system of utilizing, such as existing
Semi-coke drying combustion system or semi-coke stove air pipeline, raw coke oven gas enters after semi-coke drying combustion system for carrying out to semi-coke
It is dry, into air pipeline after be pyrolyzed for combustion with meagre oxygen.
When semi-coke furnaceman makees: leaking into coal bunker by gate valve if any a small amount of raw coke oven gas can be collected by collection ballute,
Burning in semi-coke drying system is sent by recovery channel, heat is provided, reach the loss raw coke oven gas purpose in recycling coal bunker.It returns
When receipts system breaks down, diffuse channel top cover 14 is opened, furnace roof excludes raw coke oven gas, after system is normal, starts recovery system, closes
Close diffuse channel top cover, system normal functional operation.
