Continuous sludge oxygen-control low-temperature cracking and carbonizing integrated device

Abstract

The invention discloses a continuous sludge oxygen-control low-temperature cracking and carbonizing integrated device. The device comprises a combustion chamber, a reaction kettle, a feeding assembly,a waste recovery chamber, a waste gas recovery assembly and a waste material recovery assembly, wherein the reaction kettle is divided into an inner kettle and an outer kettle, and the inner kettle is sleeved with the outer kettle; an inner kettle spiral propelling blade is arranged on the inner wall of the inner kettle; an outer kettle spiral propelling blade is arranged on the inner wall of theouter kettle; a feeding hole of the combustion chamber is rotationally connected with the outer kettle; a discharge hole of the feeding assembly is formed in an inner cavity of the inner kettle; a waste material recovery chamber sleeves the outer side of the end, close to the feeding assembly, of the outer kettle; a discharging hole is formed in the outer wall of the joint of the outer kettle andthe waste material recovery chamber; the top of the waste material recovery chamber is connected with an exhaust pipe; the exhaust pipe is connected with the waste recovery assembly; and the bottom of the waste material recovery chamber is connected with the waste material recovery assembly. The device can prevent generation of dioxin, sludge is easy to clean, organic matters can be completely carbonized, pathogens can be killed, the size of the sludge can be reduced to the maximum extent, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of energy and environmental protection technology, and more specifically relates to a continuous sludge oxygen control low-temperature pyrolysis and carbonization integrated device. Background technique [0002] With the gradual attention to environmental issues, energy conservation and environmental protection have become the development themes of various countries, and how to effectively solve sludge treatment is one of the major issues. Sludge treatment must ultimately achieve reduction, harmlessness, and resource utilization, turning waste into treasure and becoming a new renewable resource. [0003] At present, the existing sludge treatment equipment usually adopts the treatment method of high temperature incineration. During the treatment process, the chlorine-containing organic matter in the sludge will generate dioxin under the action of a certain range of temperature, and the toxicity of dioxin will...

Problems solved by technology

[0003] At present, the existing sludge treatment equipment usually adopts the treatment method of high temperature incineration. During the treatment process, the chlorine-containing organic matter in the sludge will generate dioxin under the action of a certain range of temperature, and the toxicity of dioxin will be very high. Causes serious pollution to the environment; and the sludge is easily bonded to the inner wall of the equipment during the treatment process, making it difficult to be treated
