Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies of the prior art, to provide a kind of municipal sewage that can realize the three-phase separation of the liquid phase, the gas phase and the solid phase of the sludge treatment, and the treatment process of the precipitation of the three phases is harmless. Sludge pyrolysis treatment device to overcome the defect that the traditional treatment method of municipal sludge is easy to cause secondary pollution again

Embodiment Construction

[0039] Examples such as Figure 1-3 As shown, a municipal sludge pyrolysis treatment device includes a feeding device for feeding, a thermal conditioning device for preliminary treatment of municipal sludge, and a pyrolysis device for pyrolyzing semi-dried sludge. A carbonization device, a heating device for supplying heat to the whole device, and an exhaust gas treatment device for treating the tail gas of the whole device.

[0040] The feeding device includes a silo for storing materials (sludge), a screw (auger) for conveying materials, and a feeding metering system for calculating the flow of materials.

[0041] The feeding device is arranged in two groups, and one group is connected with the thermal conditioning device for transporting the sludge to the thermal conditioning device;

[0042] The other group connects the thermal conditioning device with the pyrolysis carbonization device, and is used to transport the semi-dried sludge generated by the thermal conditioning ...

Abstract

The invention discloses a municipal sludge pyrolysis treatment device for whole-course closed negative pressure, solidifying heavy metal in sludge and avoiding secondary pollution so as to overcome the defect that a traditonal treatment method of municipal sludge is easy to cause secondary pollution. Meanwhile, the invention also discloses a municipal sludge pyrolysis treatment packaged technologywith the application of the above device, comprising the following processes: a thermal tempering separation process, a pyrolysis carbonization process and a tail gas treatment process. By the technology and the device, resource utilization of municipal sludge can be realized, cyclic development of ''treating waste by waste'' can be achieved, energy recycling of municipal sludge is realized, andexternal energy is reduced. By the whole technological process, heat balance can be realized, and secondary environmental pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a process and a device for treating municipal sludge by using the principle of pyrolysis to realize three-phase separation and achieve the effect of environmental protection disposal. Background technique [0002] With the rapid development of China's economy and the deepening of urbanization, urban production, domestic sewage treatment capacity and sewage treatment rate continue to increase, and the municipal sludge output of sewage treatment plants has also increased. However, in the development of sewage treatment in our country, although municipal sludge treatment should be one of the important links in the sewage treatment process, due to long-term lack of understanding and neglect, the municipal sludge treatment that should have accounted for 10%-20% of sewage treatment costs The issue of sludge treatment and disposal has been shelved for a long ti...
