Description

The invention relates to a device for disposal of faecal smells, bacilli, tobacco smoke or the like from the Breathing air, in the housing of two chemisorption masses kete are arranged at a distance from each other, whereby in the space between the chemisorption mass pa keten is a fan.

Such a device is known from US 35 77 710, whose filter mass packages the most diverse On can own construction. The different filter masses are used in the known device in specially for this formed supporting and holding elements arranged.

The US 35 09 697 shows a similar device as a component an air conditioning system, with various measures for sound insulation are provided.

However, it has been found that the two before standing devices are not sufficiently safe unit can be prevented from leaving the air flow particularly resistant germs, Bak terien and the like. contains.

The invention is based, based on the task State of the art described above a device for disposal from faecal smells, bacilli, tobacco smoke or the like to create the air we breathe, in which the airflow leaving it to a much greater extent of germs, bacteria or the like is exempt.

This object is achieved in that in the flow direction of the breathing air to be cleaned the two Chemisorption mass packages together have the following stratification:

A layer of soda lime, a second layer of expanded Substances with a high capillary ratio, which with or polybasic carboxylic acids are impregnated, a third layer, also consisting of bulking agents with a high capillary ratio, impregnated with alkaline iron (II) hydroxide solution (Fe (OH) ₃) and a fourth layer of activated carbon.

The change alkaline / acidic between the second and third layers leads to many bacteria, germs ud. The like both a strongly alkaline and a strongly acidic Can survive milieu, but the sudden change of milieu have not grown from the pressure side of the device Clean air flow are removed.  

The individual layers of chemisorption can be advantageous bulk packages separated by fleece filters or be be limited, as this results in a largely dense, however particularly permeable for the passage of the air flow Separation can be realized.

In the following, the invention is illustrated by an embodiment explained in more detail with reference to the accompanying drawing.

A case-like device 1 for eliminating faecal odors, bacilli, tobacco smoke or the like. from the breathing air is provided with a chemisorption mass package 2 on its intake side. Downstream of the chemisorption mass package 2 , a fan 3 is arranged, on the pressure side of which a further chemisorption mass package 4 is arranged. From the chemisorption mass package 4, the air flow into a blow-out part 5 of the case-like device 1 . The blow-out part 5 is connected to a blow hose 6 . An electronic monitoring and control unit 7 is arranged in the area between the chemisorption mass packages 2 and 4 .

To reduce noise, the fan 3 is clamped between the two chemisorption mass packets 2 and 4 , so that the chemisortpion mass packs 2 and 4 are used not only for odor and / or bacteria removal but also for suction and pressure-related sound insulation.

The chemisorption mass packets 2 and 4 are formed from several layers, namely a first layer of soda lime, then a second layer consisting of expanded substances with a high capillary ratio, these substances being impregnated with mono- or polybasic carboxylic acids, a third layer also consisting from expanded materials with a high capillary content, soaked with alkaline iron (III) hydroxide solution (Fe (OH) 3), and a fourth layer of activated carbon.

This layer sequence is arranged on the suction and pressure side of the fan 3 .

It is very effective in eliminating faecal odors simultaneous killing of bacilli and / or germs, pollen, Mushrooms and tobacco smoke, with the individual layers through Filter fleeces are separated from each other and suction and pressure on the side of the layer sequence, fleece filters to differentiate the suction and pressure side free space are attached.

Claims (3)

1. Apparatus for removing faecal odors, bacilli, tobacco smoke or the like from the breathing air, in the housing of which two chemisorption mass packets ( 2 , 4 ) are arranged at a distance from one another, with a fan in the space between the chemisortpion mass packets ( 2 , 4 ) ( 3 ), characterized in that in the flow direction of the breathing air to be cleaned, the two chemical sorption mass packages ( 2 , 4 ) together have the following stratification:
  • a) a soda lime layer,
  • b) a second layer of expanded substances with a high capillary ratio, which are impregnated with mono- or polybasic carboxylic acids,
  • c) a third layer, also consisting of bulking agents with a high capillary ratio, soaked with alkaline ferric hydroxide solution (Fe (OH) 3) and
  • d) a fourth layer of charcoal.
2. Apparatus according to claim 1, characterized in that the individual layers through fleece filters from each other are separated.
3. Device according to claim 1, characterized in that the fourth layer of charcoal on the exhaust side is limited by a fleece filter.
