Definitions

• the present invention relates to a method of com ⁇ bating micro dust, primarily in stables.
• the dust originates both from the animals them ⁇ selves, from their fodder and possible bedding, and from the ventilation air.
• the dust particles have a certain positive electric charge, and it has been close to hand to seek to combat the dust by means of ionizing appara ⁇ tuses, but these have proved to be of a very poor ef ⁇ ficiency.
• a more effective method is to spray out atomized rape oil in the stable air, this having a pre ⁇ cipitating effect on the dust, but this solution is very expensive if satisfactory results should be obtained, and besides the precipitated oil gives rise to substan ⁇ tial difficulties, because it exhibits itself as a greasy layer all over the place.
• the invention is based on the consideration that in connection with dust combating in a different field, viz. for pre ⁇ venting a whirling up of macro dust on dusty roads and open spaces, it is known to spread out certain salts or solutions thereof, notably magnesium chloride, which is indicated to be active in being highly hygroscopic; by attraction of water from the air the water is bound, even after the salt crystals having been dissolved, and thereby the loose dust will be through-moistured and bound. This is not particularly relevant for a solution of the problem here discussed, but it is suitable to explain the invention on this background.
• the micro dust is corn- batted by the method stated in the characterizing clause of claim 1, i.e. by injecting a solution of potassium chloride into the room air through atomizer nozzles at a level well above the floor, such injection being ef ⁇ fected only briefly some few times a day, e.g. through 5-20 secon s 5-25 times every 24 hours.
• a solution of potassium chloride into the room air through atomizer nozzles at a level well above the floor, such injection being ef ⁇ fected only briefly some few times a day, e.g. through 5-20 secon s 5-25 times every 24 hours.
• it is not suitable to apply the agent or the solution directly to the floor surface while on the other hand it is highly advantageous to produce a reasonably even distribution by an injection at a higher level.
• Potassium chloride as a solution is obtainable with a concentration of approximately 38%, but it is perfect ⁇ ly possible to make use of a solution of a lower concen ⁇ tration, e.g. even down to 10-15%.
• the invention can be realized in a very simple manner, as it can be suf ⁇ ficient to mount in the stable, in a high level therein, a hose provided with suitably mutually spaced fan nozzles for horizontal or slightly upwardly directed injection of the said solution, which is supplied to the hose from a suitably controlled pressure source. All according to actual desires there may be arranged for a more or less even distribution of the injection from many different places, depending also on the general layout of the stable or room.
• connection wjLth the invention it has been found that just potassium chloride gives rise to the desired effect without noticeable negative side effects, but it may well be possible that there exist other and cor ⁇ respondingly applicable substances, which will thus also be covered by the invention.
