AI Technical Summary

Technical Problem

Existing sludge granulators are difficult to effectively dewater and granulate under low-cost and low-maintenance conditions, and they also suffer from wear and high energy consumption.

Method used

The sludge, which has a moisture content of 80%, is reduced to 50%-65% by pre-dewatering. It is then transported to the granulation section by steam-heated spiral blades. The granulation process does not require forced pressing. Stable particles are formed by evaporation blades and granulation blades, avoiding wear.

Benefits of technology

It achieves efficient dehydration and granulation, reduces energy consumption and wear, meets the requirements of co-processing of municipal solid waste incineration, and is suitable for energy-saving and consumption-reducing sludge treatment in the environmental protection field.

Abstract

The present application relates to a kind of sludge dewatering granulator, including transmission mechanism and dewatering granulator main body, dewatering granulator main body is divided into dewatering section and granulating section along sludge conveying direction, at least one hollow spindle is arranged inside dewatering granulator main body, transmission mechanism drives hollow spindle, hollow spindle is close to the end of transmission mechanism and is provided with rotary joint into steam, sealing bearing set is arranged at the bottom end of hollow spindle in granulating section, the top of dewatering section is provided with feed inlet and exhaust port, the inside of the granulating section is provided with granulating blade, and the bottom end is provided with end hole plate, the sludge dewatering granulator not only avoids the deposition of semi-dry sludge in horizontal equipment, wear and tear, the disadvantage of low thermal efficiency, but also avoids the defects of large enough motor power consumption and great wear and tear during semi-dry sludge granulation, and the sludge drying and granulating effect is good, and at the same time, it meets the requirements of sludge granulation for life garbage incinerator collaborative incineration.
