Abstract

An efficient and environmentally friendly sludge filtration and drying treatment system, comprising a bottom plate (1), a support plate (2), a recovery device (3), a frame device (4), a fan device (5), and a pipeline device (6) , a lifting device (7), a motor device (8) and a concentration device (9), the base plate (1) is provided with a first support block (11) and a first roller (12), and the support plate (2) is provided with a second A through hole (21), the first spring (22), the first vertical bar (23) and the second spring (24), the recovery device (3) includes the recovery box (31), the first filter screen (32), the sealing ring (33), the first pipeline (34), the frame device includes the first frame body, heat dissipation frame, heating rod, first bending rod, and the fan device includes the second frame body, the second vertical rod, the first motor, the first A rotating shaft and fan blades, the invention can fully dry the sludge.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an efficient and environmentally friendly sludge filtration and drying treatment system. Background technique [0002] At present, all cities and most counties in my country already have urban sewage treatment plants. The total amount of sewage treated by sewage treatment plants has exceeded 48 billion cubic meters each year, and more than 33 million tons of sludge with a moisture content of 80% are produced every year. Although the urban sewage treatment rate has reached 90%, the sludge treatment devices of urban sewage plants have not kept pace. The harmless disposal of sludge is only about 56%, and about 15% of the sludge is unknown. It can be seen that the traditional concept of heavy water and light mud has not changed. Nearly half of the sludge has not been harmlessly treated, and a large amount of organic matter and energy in the sludge have not been utili...

AI Technical Summary

Problems solved by technology

The current sludge drying technology mainly has the following problems: (1) Volatile organic compounds (VOCs) are easily generated during the sludge drying process, causing secondary pollution and increasing subsequent treatment costs; (2) The process is complicated and the equipment occupies Larger land area, higher energy consumption

However, it cannot recover the water contained in the sludge, and needs to dry the water in it, which wastes resources and energy; at the same time, it can only use the heated air once and cannot be reused, resulting in a waste of energy ; and it can't intensify the flow of air inside it, so that the drying efficiency is not high, the efficiency is low, and it can't effectively save time
