Problems solved by technology

The various methods currently used, such as anaerobic digestion, drying and dehydration, incineration, etc., have limited reduction effects or high costs, and all belong to process treatment, either front-end treatment or back-end treatment
Although my country's policies on sludge treatment and disposal have become more and more stringent, no major breakthroughs have been made in the development of the industry, and the lack of technology has become the biggest shortcoming. High-efficiency and low-cost treatment technologies are in urgent need

Embodiment 1

[0021] The municipal sludge with a water content of 80% is transported to the pipeline-transported heating unit through the sludge pump 3, and heated during the transport of the sludge to a temperature of 120-150°C. The sludge enters the pressurized part of the reaction kettle from the pipeline conveying heating part through the sludge pump, and at the same time, the waste gas, steam and sludge generated during heating are continuously pumped out by using the vacuum tank to connect the suction port 204. After all the sludge enters, the valve is closed, and the drive motor 4 is The valve in the reaction kettle 2 provides power, and nitrogen gas is fed into the reaction kettle to continuously increase the pressure to 12-22MPa, so that the biomass in the sludge is cracked and the water in it is released. The reacted sludge is discharged from the discharge port 202, and 75% of the water in the sludge can be removed by ordinary mechanical dehydration to obtain biochar, which can be ...

Abstract

The invention discloses a sludge carbonization all-in-one machine which comprises a pipeline conveying type heating part and a reaction kettle pressurizing part, wherein the pipeline conveying type heating part comprises a spiral winding type conveying pipeline and a heating device on the exterior of the pipeline; the reaction kettle pressurizing part comprises a high-pressure-resisting reaction kettle body and a pressurizing apparatus. The invention also discloses a sludge dehydration and carbonization method which comprises the following steps: heating and pressurizing to pyrolyze biomass inthe sludge into charcoal; converting internal water into free-state water; dehydrating to obtain charcoal.

Description

technical field [0001] The invention relates to a sludge treatment device and method, in particular to a sludge carbonization integrated machine and method. Background technique [0002] With the acceleration of urbanization and the rapid development of industry, a large amount of sludge has been brought. Municipal sludge includes river sludge, etc. Industrial sludge includes printing and dyeing sludge, paper mill sludge, pharmaceutical factory sludge, slaughterhouse, distiller's grains, seafood processing plants, etc. Hazardous waste sludge includes oil sludge generated in the process of petroleum and petrochemical production , coal coking sludge, electroplating sludge, medical waste, mining sludge, etc. It is predicted that the sludge output in 2020 will reach 60-90 million tons. The purpose of sludge treatment is firstly "reduction, stabilization, and harmlessness", and secondly, the possibility of "recycling". The various methods currently used, such as anaerobic diges...
