Summary of the invention

Problem to be solved in the utility model is to make waste gas in the incinerator rise to before furnace roof discharged by exhaust chimney, waste gas can block in stove and contained oxygen is utilized the incinerator waste gas oxygen content reduction device of furnace roof high temperature completing combustion under the delay state.

For addressing the above problem, solution of the present utility model is: incinerator waste gas oxygen content reduces device, and this device is located at the adjacent exhaust chimney part in incinerator body of heater top, but wherein establishes the spacer of a detention waste gas in the body of heater top.

Above-mentioned spacer is a Y circular row hollow tube less than body of heater top internal diameter and the opening of upper and lower pipe end, the spacer of this hollow tube form is in the flange of last pipe end outer rim forming device fixing hole, the corresponding locking of flange with body of heater, exhaust chimney, its pipeline section stretches that to put body of heater inner and coat refractory material inside and outside tube wall, and the hollow tube tube wall of spacer can be laid perforation.

Before discharging by exhaust chimney owing to incinerate that the waste gas that produces rises in the stove, the spacer of this hollow tube form can form a retardation to waste gas in furnace roof, and make waste gas can't arrange the intake and exhaust chimney, utilize the high temperature of furnace roof to be burnt totally in this delay state contained oxygen of waste gas of ordering again, thereby reduce the oxygen content of combustion gas.
