Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a flow chart of domestic sludge pyrolysis treatment process, figure 2 It is a structural schematic diagram of domestic sludge pyrolysis treatment, and the domestic sludge pyrolysis treatment process includes the following steps:

[0022] 1) Turn on the sludge pump 1, the sludge pump 1 sends the sludge into the dehydrator 2, the dehydrator 2 dehydrates the sludge and then enters the elevator 3, and the elevator 3 lifts the dehydrated sludge and enters it into the pyrolysis furnace 4 tops.

[0023] 2) A stirring shaft 5 is arranged in the pyrolysis furnace 4 along its axial direction, and stirring blades 6 are evenly distributed on the stirring shaft 5, and the motor 7 drives the stirring shaft 5 to drive the stirring blades 6 to stir in the pyrolysis furnace 4; the pyrolysis furnace 4 The interior is divided i...

Abstract

The invention discloses a domestic sludge pyrolysis treatment process. After the sludge is sent to a dehydrator by a sludge pump for dehydration; The flue gas in the dry distillation section enters the preheating and drying section directly; the flue gas entering the preheating and drying section passes through the dust removal after heat dissipation; the flue gas entering the dry distillation section enters the high temperature gas purifier; The purification system separates tar and saturated water gas; the sludge charcoal is cooled and discharged by circulating saturated water gas. The sludge pyrolysis technology used in this process is an effective way to reduce, stabilize, harmless and recycle sludge, with high energy utilization rate, high capacity reduction rate and low operating cost; after combustion, the waste gas that needs to be treated The amount is small; the sludge does not need to be landfilled, and the incomplete incineration process is transformed into a gas complete combustion process, so that the emission of sludge carbon solid particles is extremely small, and it is more environmentally friendly.

Description

technical field [0001] The invention relates to a domestic sludge treatment process, in particular to a domestic sludge pyrolysis treatment process. Background technique [0002] The current domestic sludge is disposed of through landfill, and the organic matter in the domestic sludge cannot be decomposed, which is prone to secondary pollution. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a more environmentally friendly domestic sludge pyrolysis treatment process that can effectively pyrolyze the organic matter in the domestic sludge. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] Domestic sludge pyrolysis treatment process, the process includes the following steps: [0006] 1) Turn on the sludge pump, the sludge pump sends the sludge into the dehydrator, the dehydrator dehydrates the sludge and then ente...
