A device and method for treating organic matter with high moisture content

Abstract

A device and method for treating an organic matter having high water content. The device comprises: a feeding unit (1), a hydrothermal drying unit (2), a press filtering unit (3), a liquid storage unit (4), a thermal conversion unit (5), and a solid storage unit (7); an organic matter having high water content to be treated is capable of entering the feeding unit (1), the hydrothermal drying unit (2), the press filtering unit (3), and the thermal conversion unit (5) in sequence; the hydrothermal drying unit (2) is provided with an air inlet and an air outlet; the hydrothermal drying unit (2) is provided with a first heating device and a first temperature control device; the press filtering unit (3) is a mechanical press filtering unit; the thermal conversion unit comprises a second heating device and a second temperature control device. The water content of the organic matter having high water content can be well reduced by means of in-situ hydrothermal dewatering, and the organic matter having high water content subjected to water content reduction is thermally converted to obtain a product having high quality; the device is an integral combined device, so that the operation is convenient, and the treatment efficiency of the organic matter having high water content is high.

Description

technical field [0001] The invention belongs to the technical field of energy and resource utilization of organic solid waste with high moisture content, and particularly relates to a device and method for treating organic matter with high moisture 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, the national sludge treatment rate only reached 33%, and about 67% of the sludge was not treated harmlessly. threat to the ecological environment. It is estimated that my country's sludge production will reach more than 80 million tons in 2020, so the proper disposal of sludge is imminent. Thermochemical conversion technologies such as incineration, thermal conversion and gasification are one of the effective ways to deal wi...

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
