Background
With the development of urban construction and the improvement of the living standard of people, the generation amount of urban domestic sludge is increased, for example, land construction can generate a large amount of sludge or solid sediment substances generated after sewage is treated by a sewage treatment plant, and the sludge generally comprises organic residues, bacterial cells, inorganic particles, colloids and the like and complex heterogeneous bodies. The sludge treatment method is generally divided into a physical method and a biochemical method, wherein the physical method is generally drying treatment, namely removing most of water contained in the sludge, and then performing harmless treatment on the residual slag or converting the residual slag into other use. Compared with biochemical method, the physical method has the advantages of small occupied area of equipment, short treatment period, difficult secondary pollution and the like.
The existing sludge drying method mainly adopts a physical method, and is divided into direct drying, indirect drying and direct-indirect combined drying according to the contact mode of a medium and sludge, wherein the essence of the direct drying is convection drying, namely hot gas generated by a combustion chamber is directly contacted and mixed with the sludge, and the sludge is heated to evaporate water in the sludge to finally obtain a dry sludge product. The essence of indirect drying is conductive drying, i.e. hot gas generated by a combustion chamber passes through steam and a hot oil medium to heat the wall, and then the heat is transferred to wet sludge through the wall, so that the moisture in the wet sludge is evaporated. Direct-indirect combined drying is a combination of direct drying and indirect drying.
Because the sludge is produced in the sewage treatment process, the sludge has larger water content, when the sludge is dried and incinerated, the water content in the sludge needs to be reduced, the sludge can be dried more quickly, and the use of more fuels is reduced, but the existing sludge incineration equipment has the problems of poor sludge dewatering effect, excessive fuel consumption and low drying efficiency.
