More Information
Summary:The invention discloses a method for preparing smokeless carbon by using household garbage, which takes pipe sludge, organic waste or a mixture of the pipe sludge and the organic waste as raw materials, and the process is as follows: 1) the household garbage is dried to contain moisture content of 15 percent to 20 percent; 2) the dried household garbage form blocks are placed in a charring kiln for combustion for 42-54 hours at the temperature of 100-200 DEG C; 3) the air flow is adjusted to lead the temperature to rise to 400-500 DEG C, and the combustion is continued for 48-56 hours at the temperature of 400-500 DEG C so as to cause the form blocks to be charred and desulphurized; and 4) the combustion is stopped, and situation is maintained for 42-56 hours under the condition of isolating oxygen. The household garbage can generate heat by self through burning, the combustion temperature is controlled by adjusting the air flow, and extra heat is not needed. The prepared smokeless carbon has the heat product
