Sludge filtering and drying purification treatment system

Abstract

The invention relates to a sludge filtering and drying purification treatment system. The sludge filtering and drying purification treatment system comprises a bottom plate (1), a supporting plate (2), a recovery device (3), a frame body device (4), a fan device (5), a pipeline device (6), a lifting device (7), a motor device (8) and a concentrating device (9), wherein a first supporting block (11) and first roller wheels (12) are arranged on the bottom plate (1), the supporting plate (2) is provided with first through holes (21), a first spring (22), first vertical bars (23) and a second spring (24), the recovery device (3) comprises a recovery box (31), a first filter mesh (32), a sealing ring (33) and a first pipeline (34), the frame body device comprises a first frame body, a heat dissipating frame, a heating rod and a first bent rod, and the fan device comprises a second frame body, second vertical bars, a first motor, a first rotating shaft and fan blades. The system can be used for carrying out sufficient drying treatment on sludge.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sludge filtration and drying purification 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 utilized as resources. This not ...

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
