FR2465851A1 - Tomb ventilation system with opt. plastics vent siphon tube - to treat exhaust with liquid disinfectant - Google Patents

Abstract

System is described for purging of sealed tombs with oxygen or carbon dioxide to avoid unhygienic contamination of the surrounding environment by corpse decomposition products. It optionally involves use of a vent siphon tube made of plastics material and partially filled with disinfectant solution of e.g. phenol. Pref. the siphon tube is fitted with an inlet grill to exclude solids.

Description

 The main object of the present invention is decompression, the purification of putrefaction gases caused by the natural decomposition of bodies in coffins deposited in watertight vaults. In the case which interests us, the gases are evacuated to the open air after having been previously filtered, deodorized as well as the neutralized bacteria, (interchangeable filters).

 The proposed method which is the subject of the present invention is intended mainly for vaults in waterproof prefabricated reinforced concrete, vitrified or asphalted, in sheet metal treated against corrosion or in stainless steel in sheets, as well as in laminated polyester or other products allowing this realization.

Given the new regulations concerning the rotation of places in city cemeteries of medium and great importance (Hygiene and environment) septic liquids from the decomposition of corpses no longer having to be naturally evacuated in the basement, watertight vaults allow better pollution control, provided that efficient equipment is used and which has received the favorable opinion of the Council
Superior of Public Hygiene of France and the Approval Number.

 In the case of depositing a coffin in a watertight vault, the body must not, under any circumstances, be buried in a plastic cover whatever the model proposed; nevertheless, the corpse can be placed in a bottom of a coffin called a bowl, rubberized fabric to temporarily hold the liquids released during the transfer. The invention recommends to accelerate the decomposition of the body to fix on the walls of the vault a device allowing the admission of Industrial or other oxygen, in proportion to be defined in liters per second flow according to the importance of the boxes provided in the vault.

 The compression and purification of gases takes place naturally by the purifying filter in the open air.

 It is essential to provide in the vault, a mixture of sawdust of oak with lime granules in order to bring down the hygrometry on the one hand, and to capture the liquids which will flow from the bottom of the coffins on the other go.

 In-- in the case of unregulated cemeteries, we can plan to replace the injection of oxygen with C.0.2 (Carbon dioxide) in sufficient quantity using the same device mentioned above, in order to place the interior of the vault under neutral atmosphere and keep keep the bodies. It is also possible to use formalin or other disinfectant.

The drawings shown and described are given here only for schematic, non-limiting indication and are subject to numerous variants of embodiments and applications as a product.
New industrial.

 FIG - I - represents, seen in section, a sealed cement cellar (I) covered with a concrete plate above the ground. At the upper part of the cellar will be sealed in advance tubing primers which can receive on the one hand the arrival of oxygen coming from a bottle and having a non-return connection (3) and on the other hand, the fixing of a filter provided with an automatic valve (2) placed inside the cell acting in the event of compression coming from the putrefaction gases and after filtering evacuate them in the open air. This filter purifier and decompressor is provided with an interchangeable cartridge replaced with each deposit of coffin. You can also place in the vault a siphon proper containing in (5) formalin or other disinfecting liquid product. This siphon contains at its base a perforated grid (4) absorbing the gases which will be evacuated in (I2) to the air free. In (6) re-wicking cap of the siphon. verification and filling is done at each burial. In (I3) Asphate or vitrification.

 FIG - 2 - shows the automatic connector (3), allowing oxygen to be sent into the cellar. In (7) the movable part of the fitting screwing onto the sealed end piece and integral with the cellar.

In (8) and (9) the pressure and decompression control dials. In (IO - setting and closing the oxygen supply.

In (II) the hose bringing oxygen from the bottle.

 Of course, the invention is not limited to the embodiment shown and described and to the drawings appended as an example, but it can vary in shape, in materials of dimensions without being altered the principle of the invention, the aim being to remain within the framework of the Idea new object of this present patent

Claims (1)

IO CLAIMS- Purifier of watertight vaults by admission of oxygen and decompression in the open air, characterized by the fact that it consists of a purifier and de-decompression filter placed at an end piece integral with the watertight vault and allowing '' introduce oxygen and allow the evacuation of gases after filtering to the outside in the open air, or by a siphon provided with a grid at its base and filled with formalin or any liquid product disinfectant evaporating at the top of the cellar in the open air by an inverted pipe, after having absorbed the putrefaction gases. 2 - sealed cellar cemented or laminated polyester or other according to claim - I - characterized in that its upper part, this sealed cellar is provided with screw caps allowing if necessary, to fix a fitting or socket allowing to send oxygen into the cellar once it is sealed. 30-Cellar according to claim - 2 - characterized by the fact  that at its upper part it will be provided with a tip or socket  fitted with an automatic non-return valve, acting in the event of  overpressure of putrefaction gases which will be evacuated to the air  free.  4 - Filter according to claim - I - characterized in that  that this purifier filter consists of an interchan cartridge  geable consisting of disinfectant products eliminating  bacteria.  5 - Filter according to claim - I - characterized in that  that it can consist of a siphon fitted with a perfo grid  filled with formalin or other disinfec liquid products  tants resting at the bottom of the vault, so that the gases as well  purified are evacuated to the air automatically.  The filling of the siphon is done at the top  inside of the cellar by a screw cap with a seal  waterproof. This siphon is made of suitable plastic.  60- The oxygen injection according to claim - I - is charac  confirmed by the fact that it can be replaced by C.0.2.  (Carbon dioxide) or other disinfectants, such as  formalin.
