Abstract

The invention relates to the technical field of sludge treatment, and in particular relates to a fuel sludge preparation device, which is simple in structure and low in use cost and can improve the heat efficiency of a sludge incinerator. The fuel sludge preparation device comprises a sludge dryer which is provided with a feeding hole and a discharge hole, wherein a sludge feeding device is arranged at the feeding hole of the sludge dryer, and a sludge discharge device is arranged at the discharge hole of the sludge dryer. The fuel sludge preparation device is characterized in that a vibrating screen classifier is arranged at the discharge end of the sludge discharge device, and a fuel sludge conveying device is arranged at the discharge position of a blanking plate of the vibrating screen classifier.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a fuel sludge preparation device. Background technique [0002] The treatment methods of municipal sludge are mainly landfill, used for agricultural fertilizer and incineration. Sludge incineration treatment has some advantages that other treatment methods do not have: large sludge incineration capacity, and complete thermal decomposition of organic matter. [0003] In the sludge incineration treatment method, the direct incineration system of dewatered sludge is simple, and the initial investment in equipment is small, but it generally needs to consume auxiliary fuel; while the sludge drying incineration adds a sludge drying system, which increases the initial investment, but can effectively recover waste water. The heat generated by mud incineration reduces operating costs. If the calorific value of the sludge can be maintained or even greater than the heat balance r...
