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 a method for extracting harmful gases, which uses the possibility of extracting polluted air, especially from the point where its highest concentration occurs. In the case of fat-free pig breeding, the highest concentration is at the point where the liquid faeces are collected, so pipes with drilled holes are placed just below the grate in the liquid feces channel. Exhausted polluted air from under the grate is led outside the hall. This avoids the release of ammonia and greenhouse gases from a site that is largely involved in increasing the concentration of ammonia and greenhouse gases in the facility.
