Method and container for preparing biological carbon

Abstract

The invention provides a method for preparing biological carbon at high quality, and the method is low in cost, simple to operate and environment-friendly. The method comprises the following steps: (1) spreading carbon on the bottom of a container with an opening at the upper part, spreading kitchen garbage on carbon spread on the bottom, then spreading carbon on the layer of the kitchen garbage, then repeating the above operations until a gas is reserved between the final layer and the container opening, and sealing the container opening; (2) performing sealed anaerobic sintering on carbon and kitchen garbage in the container together with the container, and controlling the sintering temperature to be 400-700 DEG C and the sintering time to be 1 h-1.5 h; and (3) after sintering is finished, cooling the temperature in the container to be 60 DEG C or less, and opening the container, so as to obtain biological carbon. The invention also provides the container applicable to the method. The container is used to hold kitchen garbage and carbon for preparing biological carbon through sintering, and the container is simple and ingenious in structure and low in cost. By employing the technical scheme, kitchen garbage is employed for preparing biological carbon without being dried, operation is convenient, and prepared biological carbon is high in combustion value and less in ash content. Equipment for preparing biological carbon through sintering is low in cost. The method is great in environment protection value, and has constructive social meaning on solving of kitchen garbage and clean energy.

Description

Technical field [0001] The invention relates to a method for preparing biological carbon, in particular to a method for preparing kitchen waste into biological carbon. Background technique [0002] With the rapid economic development, the acceleration of urbanization and the improvement of people’s living standards, the domestic waste produced in production and life is also increasing sharply, but the corresponding urban construction capacity for waste disposal has not kept up with economic development. The pace has created the situation of "garbage siege" in major cities today. [0003] There are many ways to dispose of garbage, such as landfill, incineration, and recycling. In terms of garbage landfill, it occupies a lot of land and causes environmental pollution, especially surface pollution and air pollution, which affect the health and life of the people. Larger, so is the incineration of garbage. Therefore, the disposal of garbage has attracted more and more people and the ...

Problems solved by technology

However, there are two major bottlenecks in the existing biomass carbon production technology. One is that the steps are cumbersome, and the raw material (fresh biomass) needs a pre-drying treatment so that the water content reaches about 10% before entering the carbon production process; the other is that the cost is too high. High, reflected in manual collection costs, raw material transportation costs and energy consumption costs in the firing process

[0005] The patent number of the prior art closest to the present invention is 201110419809.4, which is called a method for preparing biomass carbon from biomass materials and a patent on a carbonization furnace. Long time, complicated equipment and high cost
