Title:
LIVESTOCK MANURE TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/116728
Kind Code:
A1
Abstract:
The present invention relates to a livestock manure treatment system, which enables rapid fermentation of livestock manure; even in winter when the temperature is low, can maximize power generation efficiency using methane gas generated during a fermentation process of livestock manure; and transforms organic wastes, such as livestock manure, into liquid fertilizer while eliminating malodors in a livestock barn. The livestock manure treatment system is configured to process wastewater discharged from a manure storage tank into liquid fertilizer and to capture the methane gas generated from the manure storage tank and use same to generate power using a methane gas generator. Further, the livestock manure treatment system is characterized in that: a filter mesh body is installed on the bottom of the manure storage tank, and a heat exchange room is provided below the filter mesh body, the heat exchange room including first and second heat exchange conduits installed therein, wherein the first heat exchange conduit is connected to a cooling water conduit for cooling a gas engine unit in the methane gas generator, and the second heat exchange conduit is connected to a water heating container including a heat exchange conduit, wherein exhaust gas discharged from the methane gas generator passes through the heat exchange conduit, thus enabling heat exchange of the manure storage tank; a vent provided on one upper side of the livestock barn is connected to a discharge conduit, wherein a spray nozzle is installed on the discharge conduit, and from the spray nozzle, fine water droplets are sprayed under high pressure into the exhaust gas, causing same to contain water; and a tip portion in a travelling direction of the discharge conduit is connected to a steam separator, causing water to fall downward and air to be discharged upward, thereby eliminating the malodors.
