Dry-type anaerobic reaction treatment device

Abstract

The invention relates to a dry-type anaerobic reaction treatment device. The dry-type anaerobic reaction treatment device comprises a reaction container and a stirring mechanism, wherein the stirring mechanism is supported on the reaction container; a charging mechanism is arranged on one side of the reaction container; a discharging mechanism is arranged on the other side of the reaction container; a heat preserving layer and a plurality of detection installation holes are formed outside the reaction container, and a methane collection port is formed in the top of the reaction container; the reaction container is divided into at least three heating regions from a charging side to a discharging side; two groups of heat exchangers are arranged at the side lower part of the reaction container respectively; each heat exchanger comprises at least three heat exchange tube groups; each heat exchange tube group penetrates through the reaction container from the charging side and is arranged in the corresponding heating region; a stirring shaft of the stirring mechanism, corresponding to each heating region, is provided with at least four stirring blades; all stirring blades are staggered in the circumferential direction along the axial direction of the stirring shaft; each stirring blade comprises a stirring box and a stirring arm; an opening is formed in the outer side of the stirring box; the stirring arm is fixed with the stirring shaft. The dry-type anaerobic reaction treatment device is reasonable in structure; the quantity of treatment units is small; the sewage treatment cost can be reduced; the anaerobic treatment efficiency can be improved.

Description

Technical field [0001] The invention relates to a dry anaerobic reaction treatment device, which belongs to the technical field of garbage treatment. Background technique [0002] At present, the problem of garbage disposal has become increasingly prominent, and all cities are facing the problem of the way out of organic garbage. As people's material life is becoming more and more abundant, the amount of waste generated is also increasing rapidly. The original simple method of simply burying garbage in the landfill can no longer cope with the rapid increase in the amount of garbage, especially the organic waste in the garbage has a bad impact on the environment. [0003] At present, there are many methods to deal with garbage to avoid the harm caused by garbage to the human living environment. Take the treatment process of organic waste in garbage as an example. At present, a simple and effective treatment method is wet anaerobic treatment technology, which is to separate the col...

AI Technical Summary

Problems solved by technology

[0004] Although the wet anaerobic treatment of garbage is applied in many projects, due to the complex pretreatment and many treatment units, the degradation rate of organic matter is low, the amount of sewage produced is large, and the treatment cost is high.

In order to improve the efficiency of anaerobic treatment, heating devices will be added in some reactors to quickly reach the required anaerobic treatment temperature for the organic waste in the reactor, but the usual reactor and length exceed 10m, due to the The material is heated as a whole, so the temperature of the material at the front of the reactor is lower than the temperature at the rear of the reactor, resulting in uneven heating temperature of the material before and after the reactor, which cannot make the material fully enter the high-temperature anaerobic fermentation working condition, and cannot further improve the organic waste degradation rate
