Definitions
- the present invention relates to a device for purifying atmospheres in general and in particular improving the functioning of refrigerated rooms such as refrigerators by absorbing and converting volatile organic compounds into compounds favorable to the metaboiism of living materials.
- the maturation of living materials leads in their metaboiism the release in surrounding atmospheres of gases of ethylene type and volatile compounds, aldehydes, amines and others
- This atmosphere present in ies refrigerators brings a certain acceleration of the metabolism of maturation of living materials, triggers them metaboiisms of slowly maturing materials, promotes the development of microorganisms, and causes mixed odors containing catalyst products accelerating the senescence of living materials in the volumes of preservations in the food chain.
- This device which is the subject of the present invention for the treatment of atmospheres is described in its particular application in the conservation of living materials in refrigerators.
- This device essentially comprises a processing and filtration unit (12) for the atmosphere of the refrigerated tanks (1) of the refrigerators.
- the filtration element (128) comprises dry matter granules also with strong oxidizing power and with reducing capacity which particularly ensures the conversion of volatile short chain compounds which would not have been transformed during their transit in the porosities (153 ) of the treatment block and transforms the longer chain pretreated compounds by physico-chemical reactions during their passage through the humidified porosities (153).
- This filtration element (128) placed above the active material treatment bioc (121) makes it possible to ensure satisfactory purification of the atmosphere for conserving living materials and results in a significant improvement in the duration of maturation in, very significantly improved hygienic conditions.
- the physico-chemical reactions by this processing and filtration block (12) allow this purification of volatile organic compounds by transformation of the carbonaceous parts into inactive and neutral gases including carbon dioxide and hydroxyl radicals in atmospheres with low relative humidity.
- FIG. 1 shows a general view of the refrigerator with its refrigerated tank (1), the lower treatment and filtration unit (12) resting on a shelf support (2).
- the shelf (3) rests on the upper plate of the processing block (12).
- This arrangement allows the installation of the device in all ventilated or non-ventilated refrigerators.
- the ventilation circuit comprises a fan (6) aspirating to the top part of the refrigerator and discharging into the annular spaces (7) (9) to supply the tank refrigerated by baffles (8).
- the air rises by heating up slightly and passing over the treatment and filtration bioc (12), then flows to exit through the top filter element (4) and (5).
- FIG. 2 represents the treatment and filtration bioc which comprises, a liquid receptacle tank (12) with its reservoir (123) and its level (124), the active material continuously humidified (121) and its filtration element ( 128).
- the active, absorbent and high porosity material (121) is arranged in a bridge to receive the gases to be treated at the central part and rests by its ends (151) at the bottom of the receptacle.
- the air discharged by the ventilation circuit arrives below the active material (121), passes through the porosities to exit in (126) (127) and rise through the filter (128) to disperse in purified air in ( 11) on materials stored in the refrigerator above the storage grids (3).
- the processing bioc is supported by an upper plate (129) which rests on the shelf support (2)
- FIG. 3 represents the functionality of the treatment and filtration bioc (12) which comprises:
- the active material (121) has porosities (153) and has a large capacity (152) allowing the path of the liquid by humidification of the capillary channels and the fractures of the porosities (152).
- This material is made up in a bioreactor by the assembly of mixed constituents of feidspaths including a pumice stone variant with a pretreatment based on mineral salts and a slightly acidified liquid containing a part of ozone.
- This material (121) in the form of a bridge rests by its lower part (151) at the bottom of the receptacle (12).
- the liquid maintained in level (132) is in communication through the orifices (191) with the liquid reservoir (123).
- the lower part of the active material (150) is completely moistened to the level (132).
- the capillaries of the fine crack type (152) and the open porosities (153) cause the complete humidification of the material up to the central part of the material bridge.
- the active liquid comprising a solution of mineral salts mixed with a portion of ozone and peroxides has an oxidizing power which can satisfactorily effect the oxidation of gases and volatile organic compounds with short and long chains from the atmosphere of conservation of living materials and passing through the humidified porous active material.
- This liquid enables active sensitization of the internal surfaces of the porosities (153) and the external surface of the material (150). This continuous humidification ensures regular treatment of the material and guarantees the efficiency of the transformation of organic compounds.
- the operation of this continuous humidification is based on the balance of relative pressures.
- the pressure at point (180) is equal to the atmospheric pressure added to the liquid height of the receptacle at level (132); this pressure (180) always remains equivalent to the pressure at point (190) of the tank bottom (160) added to the strong depression of the evacuation of the upper part of the tank (170) as and when consumption of liquid in the receptacle (122) by the active material.
- This distribution allows a regular and automatic feeding of the receptacle level (132).
- a level mount (124) makes it possible to follow the evolution of the consumption of the treatment liquid by the active material.
- a device (125) allows the filling of the liquid reservoir.
