External-adsorbing type multifunctional trolley for recovering, guiding, combusting, suppressing and removing smoke and dust from coal gas

The utility model belongs to the technical field of coking of coking furnaces and relates to an external-adsorbing type multifunctional trolley for recovering, guiding, combusting and removing smoke and dust from coal gas. The trolley retains the mode of guiding and combusting smoke from coal gas and the mode of guiding smoke from coal gas and ejecting high-pressure ammonia into an N-1 type carbonization chamber and an N+2 type carbonization chamber, can achieve the purposes of deep processing, recovering, reusing and energy saving, is low in manufacturing cost and operation cost and can achieve a high economic profit and a good environmental protection effect. According to the technical scheme of the utility model, a travelling device is arranged at the bottom of the frame of the trolley, a movable adsorbing and guiding pipe and a fixed adsorbing and guiding pipe are arranged on the frame of the trolley, the movable adsorbing and guiding pipe is inserted into the fixed adsorbing and guiding pipe, the fixed adsorbing and guiding pipe is communicated with a smoke inlet of a carbonization chamber, a coal gas inlet of a system for combusting and removing smoke and dust is communicated with a second smoke outlet on the top of the coal carbonization chamber, and the smoke outlet of the system for combusting and removing smoke and dust is communicated with a dust collecting and removing pipe on the top of a coking furnace. The multifunctional trolley provided by the utility model can be widely applied to the field of coking.
