Title: Process for the collection and removal of harmful gases or putrefaction gases by means of hoods floating in the liquid manure
Inventor: HUNKEMOELLER JOSEF
IPC: A01C3/02
Filed: 1989-02-14
Abstract: The collection and removal of harmful gases above the liquid-manure surface is characterised by a gas-tight hood which floats in the liquid manure. The surface of the cover is designed so that material (faeces, urine, rain and the like) falling down onto the hood from above can slide off into the liquid manure. Under the hood, the gases generated in the liquid manure are collected and are discharged separately via a pipe/hose system. The pre-eminent object of this technique is to reduce the fraction of harmful gases in the stable air. The process can also be used for other surfaces which are liquid to pulpy and in which putrefaction gases are generated (liquid compost).
