Sludge treatment equipment and process

Abstract

The invention relates to sludge treatment equipment and a sludge treatment process. The equipment comprises a sludge conveyor, a sludge crushing former and a sludge dryer, wherein a pair of sludge crushing rollers and a pair of sludge strip compression molding rollers driven by a variable-frequency motor are arranged from top to bottom in a sludge hopper of the sludge crushing former; the inner cavity of the drying cabin of the sludge dryer is partitioned into a drying chamber and a circulating air heating chamber; a plurality of layers of stainless steel mesh belt conveying tables are formed in the drying chamber; the discharging hole of the sludge hopper of the sludge crushing former is positioned above the conveying start end of the topmost layer stainless steel mesh belt conveying table in the drying cabin. When applied to an urban domestic sludge treatment process, the sludge treatment equipment and the process have the remarkable advantages of high durable treatment capacity, short period, high efficiency, good treatment effect, avoidance of secondary pollution, environmental friendliness, stability and safety in equipment running, low energy consumption, high degree of automation and the like. The sludge treatment equipment and the process are high in input-output ratios and have good popularization and application prospects, and good social benefit can be achieved.

Description

technical field [0001] The invention relates to a sludge treatment equipment and process, which are used for efficiently and batch-processing urban domestic sludge and reducing environmental pollution caused by urban domestic sludge. Background technique [0002] With the development of urban construction and the improvement of living standards, the generation of urban domestic sludge is also increasing, and the long-term accumulation will greatly affect the urban environment and air quality. Municipal domestic sludge has a high water content (about 80%), making it difficult to treat it effectively and in batches. Some current treatment methods, including biochemical means, have the disadvantages of large site occupation, long treatment cycle, high energy consumption, and easy Therefore, there is an urgent need for a more efficient and reasonable urban domestic sludge treatment plan.
