designation:

Air improvement system for barn buildings.

Scope of production:

This provision relates to an air improvement system for installation by slurry ducts in connection with housing buildings. The purpose of the production is to reduce especially ammonia and odor emissions in and around the barn.

The air improvement system is a separate system that can be installed independently of the other ventilation systems of the stable. The system thus works to suck air away from the gill surface via spot extraction located at various locations above the gutter duct or along the gutter duct. The air is passed through an air purification plant for the reduction of especially ammonia and other odorous substances before the air is released into the open air, or possibly. reused in the stable.

Prior Art:

Floor extraction systems for slurry ducts are known, as various types of floor extraction systems have been installed over the years, the purpose of which has been to ventilate the stables. These systems differ from the production in that the main aim has been to ensure the total and necessary ventilation through the floor extraction system.

The technical problem:

The air quality in and around a barn, especially pig stables, is often poor due to evaporation from the slurry channels in the stables. This is to the detriment and disadvantage of animals, stables and neighbors of the stables.

With the production, it is possible to improve the climate and the environment in and around a stable. The stable can be ventilated in the traditional way, typically via ceiling ventilation, while a smaller airflow is sucked away from the slurry surface to remove especially dust, ammonia and other odors.

Pen nve technique:

What is new about the production is that the system is a separate system that operates independently of the other ventilation system of the barn. In winter periods, where the heat is typically desired to be kept in the barn, the purified air may be used. reused in the stable.

The system reduces the ammonia and odor emission problem by removing the air close to the main problem source - the manure.

In existing stables with slatted floors, one or more point extractors are typically installed at each site. In case of multiple point extraction at one point, point extraction panels can be used for mounting directly on top of the slatted floor.

The technical impact:

By using the air improvement system, it is ensured that even at very low airflow at the point extraction, ammonia and other odorants are continuously removed as they are developed and released into the slurry duct. A large part of the substances are removed before they are mixed with the rest of the air in the barn, which results in a significantly better indoor climate in the barn with far less ammonia and odor emission. This means better indoor climate for animals and housing staff. Overall, ammonia and odor emission from the other ventilation of the barn are significantly reduced, which means better environment for the surroundings.

When establishing point extraction panels as claimed in claim 2, a high collection of ammonia and odorants from the slurry surface is ensured.

List of Figures:

Figure 1 shows an example of the air improvement system according to the production installed in a stable. Figure 2 shows a principle sketch of the air improvement system.

Figure 3 shows an example of installation of point extraction panel on slatted floor.

Figures 4 and 5 show examples of different types of point extraction panels.

Example Examples: Figure 1 shows how the point extractor is established at each site. Through a complete pipe system, the air is drawn to an air purification plant, after which the treated air is discharged into the open air or returned to the stable. Several point extraction panels are connected via a single pipe system to a central air purification system.

Figure 3 shows how the point extraction panel can be installed on top of the slit floor. The individual point suction nozzles are passed down through the slit floor.

Claims (2)

1. Air improvement system for housing buildings consisting of point extraction (1) mounted, for example, as a panel on top of the slatted floor or point extractor integrated in other housing fixtures such as partition or split floor, coupled to a pipe system (2) connected to a blower (3) which conducts it the slurry duct absorbed air into an air purification system (4), located either inside or outside the stable. From here, the purified air is discharged into the open air (5) or returned to the stable (6) for any heat recovery. The air improvement system is new to the air from the slurry surface under the slatted floor via vacuum extraction and is sucked up - not all the housing air. The air extraction system point extraction panel according to claim 1, comprising a closed pipe (7) mounted on point extraction plug (8) and a connecting pipe (9) with a plug with plug (10). The point extraction panel is new in that the panel is mounted on top of a slotted floor while only the point extraction slots are passed down through the slotted floor.
