Problems solved by technology

These sludge treatment equipment have the defects of large volume, scattered layout, single function and high energy consumption.
[0003] Due to the characteristics of strong viscosity, easy to agglomerate and difficult to break, the drying process of sludge is relatively long, especially for the drying of dehydrated sludge, which consumes a lot of energy
Since the existing sludge drying process is carried out separately in each sludge treatment equipment according to the steps of dehydration, crushing and drying, it is inevitable to transfer the treated sludge from one equipment to another in each treatment stage. sludge, which increases process complexity and energy consumption

Embodiment Construction

[0016] The following description is merely exemplary in nature and is in no way intended to limit the invention, its application or uses.

[0017] figure 1 A preferred embodiment of a combined device (or device combination) 100 for sludge drying according to the present invention is shown in a perspective view. The combined device 100 generally includes a dehydration unit, a conveying adjustment unit, a crushing unit and a drying unit. The dehydration unit, the conveying adjustment unit, the crushing unit and the drying unit are generally arranged vertically together, wherein the dehydration unit is arranged at the upper part of the combined device 100, the drying unit is at the lower part thereof, and the conveying adjustment unit and the crushing unit are arranged at the dehydration unit. Between the unit and the drying unit, but the position of the conveying adjustment unit is generally higher than the crushing unit. Generally, the sludge drying process is to turn liquid ...

Abstract

The invention provides a combined device for drying sludge. The device consists of a plate-and-frame filter press at the upper part, a belt conveying adjustment apparatus, a crusher, and a horizontalsingle-cavity drying machine located at the lower part, wherein the conveying adjustment apparatus and the crusher are located between the filter press and the drying machine, and the position of theconveying adjustment apparatus is higher than the crusher and includes a conveyor for receiving and conveying sludge blocks, and the conveying speed of sludge blocks to the crusher can be controlled by adjusting the operation of the conveyor. The invention also provides a method for drying sludge with the combined device.

Description

technical field [0001] The invention relates to the field of sludge drying, in particular, to a combined device for drying sludge and a method for drying sludge using the combined device. Background technique [0002] The treatment of sewage is essential in modern cities, and a large amount of sludge will be produced with the treatment of sewage. At present, sewage treatment plants generally use the methods of concentration and dehydration to pre-treat the sludge in order to reduce the moisture content of the sludge from more than 90% to 60-80%, and the treated sludge is subsequently landfilled and solidified. or drying. Landfill is easy to ferment the sludge and cause secondary pollution to the environment, and the existing solidification or drying equipment usually has low drying efficiency and large energy consumption. sludge. It usually takes multiple sludge treatment processes to reduce the moisture content of the sludge from more than 90% to the expected moisture co...
