Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0021] refer to figure 1 As shown, an oil sludge pyrolysis carbonization furnace includes an outer cylinder body, a kiln head cover, a kiln tail cover and a rotary kiln. The outer cylinder body is obliquely arranged on the kiln head cover and the kiln tail cover. It is installed on the outer cylinder, and the gap between the rotary kiln and the outer cylinder forms a jacket combustion chamber. The kiln head cover, jacket combustion chamber, and kiln tail cover are connected. The rotary kiln The kiln tail of the kiln is equipped with an outlet component for introducing the sludge semi-coke to the jacketed combustion chamber;

[0022] A hot air pipe is arranged on the kiln tail cov...

Abstract

The invention relates to the technical field of oil sludge pyrolysis, and relates to an oil sludge pyrolysis carbonization furnace. The oil sludge is conveyed into a rotary kiln, a first spiral pushing plate drives the oil sludge to move in the rotary kiln to form pyrolysis vortexes, the oil sludge can be heated evenly, heat transfer is enhanced, sufficient pyrolysis of the oil sludge is achieved,and meanwhile oil sludge hot slag generated by oil sludge semicoke combustion is guided into the rotary furnace to serve as a heat carrier to increase heat in the oil sludge pyrolysis process; and the rest of heat is supplemented by high-temperature flue gas generated by combustion of externally supplied fuel gas or fuel oil, so that the heat utilization rate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of oil sludge pyrolysis, in particular to an oil sludge pyrolysis carbonization furnace. Background technique [0002] The carbonization furnace is a thermal equipment for heat treatment of materials, which has been in existence for more than a hundred years. At present, rotary kilns are widely used in industrial production processes such as nonferrous metallurgy, refractory materials, cement, chemicals, papermaking and solid waste treatment. The existing carbonization furnaces used for pyrolysis of oily sludge mainly use direct heating, which consumes a lot of energy. At the same time, coking of oily sludge occurs during the treatment process, which makes pyrolysis insufficient and equipment cleaning difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil sludge pyrolysis and carbonization furnace that can make the oil sludge evenly h...
