Municipal sludge regeneration and resourceful treatment device

Abstract

The invention discloses a municipal sludge regeneration and resourceful treatment device. The device comprises a device shell, a sludge dewatering assembly and a pyrolysis assembly, wherein a base isarranged at the bottom of the device shell; a sludge pump and a water outlet are arranged on the device shell; the sludge dewatering assembly comprises an extrusion plate, a connecting rod and a powermotor; a guide plate and a sliding rod are arranged in the device shell; the extrusion plate is arranged on the sliding rod; the power motor provides power for the extrusion plate; the pyrolysis assembly comprises a pyrolysis cylinder, a sludge stirring component and a deodorizer; the pyrolysis cylinder is arranged in the device shell and located at the lower end of the extrusion plate; the sludge stirring component comprises a rotating motor and an spiral conveyor; the auger is arranged in the pyrolysis cylinder; the power motor provides power for the spiral conveyor; and the deodorizer communicates with the pyrolysis cylinder and is used for treating volatilized gas. The device is reasonable in structural design, capable of conducting thorough and effective resourceful treatment on municipal sludge, low in operation and maintenance cost and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a municipal sludge recycling treatment device. Background technique [0002] Municipal sludge refers to the mud or mud cake discharged from urban sewage treatment plants after concentration and dehydration. It is rich in organic matter and nutrients such as N, P, and K. If it is not disposed of properly, it will not only easily cause environmental pollution, but also damage resources. Cause waste; At present, there are generally four types of municipal sludge treatment: sludge landfill, sludge incineration, sludge agricultural use and ocean dumping. Among them, sludge incineration refers to the combustion reaction of the organic matter in the sludge in the incinerator under the condition of a certain temperature and sufficient oxygen in the gas phase. However, due to the low content of organic matter in the sludge, the combustion process is difficult to continuously prov...

Problems solved by technology

Among them, sludge incineration refers to the combustion reaction of the organic matter in the sludge in the incinerator under the condition of a certain temperature and sufficient oxygen in the gas phase. However, due to the low content of organic matter in the sludge, the combustion process is difficult to continuously provide sufficient Therefore, sludge incineration is only incineration of sludge, and the organic matter energy in sludge has not been well utilized

[0003] On the other hand, before the sludge incineration treatment, the sludge is dehydrated by selecting the best sludge. The traditional sludge dehydration method is mechanical pressure filtration. input; direct discharge of harmful gases generated during sludge combustion can easily cause secondary pollution
