Embodiment 1

[0025] Such as figure 1 Shown, in the embodiment of the present invention, a kind of method of sludge dry distillation into charcoal, comprises the following steps:

[0026] S1. Sludge receiving. The sludge truck arrives at the weighbridge metering and marking station outside the factory gate. After the automatic metering and marking and billing, it enters the factory's automatic odor-proof closed sludge discharge area. The discharge area mainly includes Sludge receiving, conveying, storage hoppers, discharge valves and other facilities fully meet the conditions for the collection and transportation of sealed sludge transport vehicles.

[0027] S2, sludge modification, the sludge with a moisture content of 80-85% after a mechanical dehydration treatment in the sewage treatment plant is transported to the centralized sludge treatment plant by the collection vehicle, and sent to the sludge collection pool after being weighed by the weighbridge. After the sludge is conditioned a...

Abstract

The invention discloses a method for carbonization of sludge into charcoal. The method comprises: sludge receiving, sludge modifying, sludge dehydrating and drying, solid-gas separating, sludge drying and powder preparing, carbonization treatment, treatment of waste gas, and treatment of waste liquid, wherein a continuous gasification carbonization machine is used during the carbonization treatment process so as to continuously treat the sludge dry power. The invention provides the method for carbonization of the sludge into the charcoal, wherein the sludge is subjected to dehydration-drying-low temperature carbonization to form the charcoal, such that the environmental pollution problem is solved, the new energy sources are created for human, and the waste is turned into treasure.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a method for dry distillation of sludge into charcoal. Background technique [0002] With the acceleration of industrialization and urbanization, the amount of sludge in sewage treatment plants has increased sharply. The sludge in many lakes, ponds, lakes, and rivers, as well as the industrial sludge produced by industrial systems have brought great environmental problems. . How to safely and effectively treat sludge has become a major problem to be solved in the process of industrialization and urbanization. [0003] At present, there are three main types of sludge treatment methods: incineration, landfill, and resource utilization. At present, incineration and landfill are commonly used abroad. However, due to the huge investment and high cost of the incineration method, few people in China use this process. At present, landfill is generally used in China, but landfill needs t...
