Sewage sludge high-efficiency deep reduction treatment device

Abstract

The invention discloses an efficient and deep sewage sludge reduction treatment device. The efficient and deep sewage sludge reduction treatment device comprises at least one dehydration module, wherein each dehydration module comprises a two-way oil cylinder (1) and two symmetrically-arranged dehydration units (2), each of the dehydration units (2) comprises a dehydration cylinder (2.1), a supporting plate (2.2) and an extruding plate (2.3), the supporting plate (2.2) is located on the outer side of the corresponding dehydration cylinder (2.1), the extruding plate (2.3) is located on the inner side of the corresponding dehydration cylinder (2.1), and a feeding port (2.4) is formed in the dehydration cylinder (2.1).The two-way oil cylinder (1) is provided with two piston rods (1.1), and the two piston rods (1.1) are respectively connected with the extruding plates (2.3) of the dehydration units (2). The efficient and deep sewage sludge reduction treatment device performs feeding dehydration and squeezing dehydration simultaneously, improves the working efficiency, also ingeniously utilizes a feeding pressure for dehydration during squeezing dehydration, improves a power usage effect and reduces product energy consumption.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to a high-efficiency deep reduction treatment device for sewage sludge. Background technique [0002] Sludge is the product of sewage treatment. At present, a large amount of sludge produced after sewage treatment needs further treatment, and dehydration is an important part of sludge treatment. Its purpose is to remove most of the water in the sludge and make the solids highly enriched. , significantly reduce the volume of sludge to save the cost of sludge treatment, increase the calorific value of sludge and save energy, which is of great significance for the reduction and subsequent disposal of sludge. Mechanical dehydration is the most effective dehydration method with the least energy consumption. Currently, deep dehydration of sludge by conditioning and mechanical methods can generally make the moisture content reach 80%-60%. [0003] Mechanical dehydration methods and ...
