Collaborative project: Development of a 'Heat-Exchange-Scrubber' to reduce gaseous emissions and energy consumption of pig houses - subproject 1
Project
Project code: 2817501111
Contract period: 01.04.2013
- 31.03.2016
Budget: 195,359 Euro
Purpose of research: Applied research
The objective of this project was to contribute to a more environment-friendly and energy-efficient in pig husbandry. Therefore, a new plant technology (“exchange scrubber”) was developed. It is a combination of a trickle-bed reactor and a recuperative heat exchanger (HE) to clean exhaust air (particulate matter, ammonia, odor) and recover thermal energy for the heating of incoming supply air simultaneously. The investigations were carried out on a small scale pilot-plant and under practical conditions on a pig farm.While passing the HE, cool incoming supply air is heated up to the temperature level of the scrubbing water. In consequence, fossil fuel reserves are substituted, carbon dioxide emissions avoided, heating costs saved, and operating costs reduced. Supply air heating depends on temperature of outside air and scrubbing water. For outside temperatures below the scrubbing water temperature, the following applies: the lower the outside temperature, the higher the supply air heating and the heating output. Cooling effects can be seen at outside temperatures above the scrubbing water temperature.
