A municipal sludge energy treatment device and its working method

Abstract

The invention discloses an energy regeneration treatment device for municipal sludge and a working method thereof. The energy regeneration treatment device comprises a base, wherein a vertical plate and a bracket are fixed on the top surface of the base respectively; the top of a side face of the vertical plate is connected with a fixed barrel which is transversely arranged; a rotary shaft which is connected onto the vertical plate is arranged in the fixed barrel; the axis of the rotary shaft is located below the axis of the fixed barrel; a roller sleeves the outer part of the rotary shaft; the roller is provided with a plurality of material distribution barrels; the top of the bracket is connected with a squeezing box; a first hydraulic cylinder and a second hydraulic cylinder which are symmetrically arranged are mounted at the outer parts of two sides of the squeezing box respectively; a first piston plate and a second piston plate are connected with output ends, located in the squeezing box, of the first hydraulic cylinder and the second hydraulic cylinder respectively. According to the energy regeneration treatment device for the municipal sludge, disclosed by the invention, squeezing and water removal of sludge and automatic discharging of dewatered sludge blocks are automatically finished; the energy regeneration treatment device is simple and compact in structure, convenient to use, high in sludge dewatering efficiency and low in equipment cost.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a municipal sludge energy treatment device and a working method thereof. Background technique [0002] With the rapid development of society and economy, the continuous improvement of industrial productivity and human living standards, the generation and discharge of sludge have been increasing. According to conservative statistics, the global annual discharge of municipal sludge alone has exceeded 100 million tons. The disorderly disposal and spread of such a large amount of sludge has aggravated the harm to the environment and has become one of the major problems in the environmental field. In addition to a large amount of organic matter, rich nitrogen, phosphorus, potassium and other nutrients, these sludges also contain harmful components such as heavy metals, pathogenic bacteria, and parasites. Improper disposal can easily lead to secondary pollution of t...

Problems solved by technology

In addition to a large amount of organic matter, rich in nutrients such as nitrogen, phosphorus, and potassium, these sludges also contain harmful components such as heavy metals, pathogenic bacteria, and parasites. Improper disposal can easily lead to secondary pollution of the environment. Will offset the effect of pollution control and emission reduction

At present, the energy conversion of sludge has become the best way to treat sludge. Sludge is generally in a mud state. It needs to remove a large amount of water before it can be dried and other subsequent processing. The existing technology center, sewage Dewatering of sludge requires the use of special equipment such as thickeners and presses. The equipment is expensive, occupies a large area, and the operating cost is also high. It is not suitable for small-scale sludge energy treatment.
