Device and method for treating organic matter with high water content

Abstract

The invention discloses a device and a method for treating organic matter with high water content. The device comprises a material charge unit, a hydrothermal drying unit, a press filtering unit, a liquid storage unit, a thermal conversion unit and a solid storage unit, wherein the to-be-treated organic matter with high water content can be sequentially sent into the material charge unit, the hydrothermal drying unit, the press filtering unit and the thermal conversion unit; the hydrothermal drying unit is provided with an air inlet, an air outlet, a first heating device and a second heating device; the press filtering unit is a mechanical press filtering unit; the thermal conversion unit comprises a second heating device and a second temperature control device. The device has the advantages that the water content of the organic matter with high water content can be well reduced via the in-situ hydrothermal dewatering, and the organic matter with high water content after reducing of water content is thermally converted to obtain the product with higher quality; the device is an integral combined device, so that the operation is convenient, and the treatment efficiency of the organic matter with high water content is higher.

Description

technical field [0001] The invention belongs to the technical field of energy conversion and resource utilization of organic solid waste with high water content, and in particular relates to a device and method for treating organic matter with high water content. Background technique [0002] The treatment and resource utilization of organic solid waste with high moisture content has received extensive attention in recent years. Taking sludge as an example, the data shows that in 2016, the national sludge treatment capacity was about 13 million tons per day, and the national sludge treatment rate only reached 33%, and about 67% of the sludge had not been harmlessly treated and disposed of. pose a threat to the ecological environment. It is estimated that my country's sludge output will reach more than 80 million tons in 2020, so the proper treatment of sludge is imminent. Thermochemical conversion technologies such as incineration, thermal conversion, and gasification are ...

AI Technical Summary

Problems solved by technology

At present, there are problems in the recycling of high-moisture organic solid waste: due to the high water content and difficult dehydration of high-moisture organic solid waste, direct use of thermochemical conversion technology will consume a lot of energy to meet the latent heat of vaporization; In addition, due to the high water content of organic solid waste, the quality of obtained products such as thermal conversion oil is not high
