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
[0018] The following description is merely exemplary in nature and is in no way intended to limit the invention and its application or uses.
[0019] 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 combination 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 vertically arranged together, wherein the dehydration unit is arranged on the upper part of the combination device 100, the drying unit is located on the lower part thereof, and the conveying adjustment unit and the crushing unit are arranged on the dehydration unit 100. Between the unit and the drying unit, but the location of the conveying adjustment unit is generally higher than the crushing unit. Generally, the sludge drying proce...

The invention provides a combined device for drying sludge. The device consists of a belt dewaterer at the upper part, a conveying adjustment apparatus, a vertical crusher, a pair-roller type or hammer crusher, and a combined ventilated horizontal drying machine at the lower part, wherein the conveying adjustment device and the crusher are located between the belt dewaterer and the drying machine,also the position of the conveying adjustment apparatus is higher than the crusher and includes a conveyor for receiving, storing and conveying sludge blocks, and the conveying speed or feeding amount of sludge blocks to the pair-roller type or hammer crusher can be controlled by adjusting the operation of the conveyor in the hopper and the sludge blocks can be pre-crushed. 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 in modern cities is essential, and with the treatment of sewage, a large amount of sludge will be produced. At present, sewage treatment plants generally use the method 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 then carry out subsequent landfill and solidification of the treated sludge. or drying treatment. Landfills tend to ferment sludge and cause secondary environmental pollution. However, existing solidification or drying equipment usually has low drying efficiency and high energy consumption. It is difficult to reduce the moisture content of sludge while also processing a large amount of sludge. sludge. It usually takes several s...
