Method for air exchange in the stable for pigs without bedding technology focused on exhausting air from the space below raft

摘要

Described is the way of extraction of harmful gases, which uses the opportunity to suck air pollution, especially from the point where it occurs the highest concentration. When without bedding breeding fattening pigs the highest concentration is holding at the point where the liquid excrements collect, therefore, the channel area of the liquid excrements is placed just below the grid line having a drilled holes. Sucked polluted air from below the grate is led out of the hall. This will prevent the release of ammonia and greenhouse gases from sites which largely contributes to increasing concentrations of ammonia and greenhouse gases in the building.
