Abstract

The method involves carrying out evaporation taken from compressed air issued from a compressor for calorific energy. A cavity (2) of a metal block (1) is used as tank for accumulation and concentration of the condensates, where the metal block is constituted as a principal part of a machine. An input (4) is used to push condensates by the compressed air. A valve (9) is located in top of a coil that ensures a blocking of liquid in a case. An independent claim is also included for a machine for the implementation of the static process of operation that separates water from oil contained in the condensates of compressed air, comprising a metal block.

Description

DESCRIPTIF DESCRIPTION

SEPARATEUR DE CONDENSATS EAU/HUILE DE COMPRESSEURS WATER / OIL COMPRESSOR CONDENSATE SEPARATOR

La présente invention concerne une machine statique de séparation Des condensats de compresseurs constitués d'eau et d'huile . The present invention relates to a static separation machine Compressor condensates consisting of water and oil.

Cette machine fait appel à la différence de caractéristiques d'évaporation existante entre l'huile et l'eau contenus dans les condensats d'air comprimé en sortie de compresseurs. This machine uses the difference in evaporation characteristics existing between the oil and the water contained in the condensate of compressed air at the compressor outlet.

Le principe de cette machine repose sur une évaporation cyclique des condensats déclenchée par l'arrivée des condensats mélangés avec l'air comprimé . The principle of this machine is based on a cyclic evaporation of the condensates triggered by the arrival of condensates mixed with compressed air.

A chaque arrivée les condensats sont envoyés dans un évaporateur qui au fur et à mesure concentre l'huile , une évacuation de l'huile concentré s'effectue par gravitation dans un récipient . Each time the condensate is sent to an evaporator which gradually concentrates the oil, an evacuation of the concentrated oil is carried out by gravitation in a container.

La présente invention permet sans énergie supplémentaire de concentré les condensats de compresseurs sachant qu'ils sont constitués, au départ de 97% d'eau pour 3% d'huile. The present invention makes it possible without additional energy to concentrate the condensates of compressors knowing that they consist of 97% water and 3% oil.

Cette machine permet donc de réduire considérablement la quantité de condensats qu'il faut recueillir dans les bacs de récoltes de ces derniers. Cette machine est étudiée principalement pour être utilisée dans un environnement ou il peut y avoir des vibrations et aussi des variations d'accélérations comme par exemple l'application sur des engins embarqués type : trains ou camions . 25 Cette machine est constituée en figure 1 de : Un bloc métallique (1) constituant la partie principale de la machine , dans ce bloc il y a une cavité (2) servant de réservoir d'accumulation et de concentration des condensats , Une arrivée de condensats poussée par l'air 30 comprimé est située en (4) , un serpentin (3) permet de laisser monté les condensats pris à la base de la cavité (2) , ce serpentin constitué d'une grande surface et étant plus chaud que le liquide fait évaporer l'eau contenue dans les condensats à chaque cycle de monté et descente de ces derniers ; un clapet (9) situé en haut du serpentin assure un blocage du 35 liquide dans le cas ou celui-ci arriverait à ce niveau ; un filtre à air (8) permet de filtrer l'air de détente montant à chaque arrivé de condensats avant de sortir de la machine (10) ; un clapet (7) ouvert en position repos Page 1 sur 2 permet de fermer l'orifice de sortie (6) lorsque la cavité (2) est sous pression à chaque arrivée des condensats ; un récipient (11) récupère l'huile 40 concentrée ; un canal serpentin (5) permet de connecter une dérivation d'air comprimé chaud prélevée en sortie compresseur qui retourne dans le circuit d'air après avoir restitué la chaleur dans notre machine et ainsi provoqué son réchauffement. This machine can therefore significantly reduce the amount of condensate that must be collected in the harvest bins of the latter. This machine is mainly studied to be used in an environment where there can be vibrations and also variations of accelerations like for example the application on embedded machines type: trains or trucks. This machine is constituted in FIG. 1 of: A metal block (1) constituting the main part of the machine, in this block there is a cavity (2) serving as a reservoir of accumulation and concentration of the condensates, An arrival of condensate pushed by compressed air is located in (4), a coil (3) allows to let the condensate taken at the base of the cavity (2), this coil consists of a large surface and being hotter than the liquid evaporates the water contained in the condensates at each cycle of raising and lowering thereof; a valve (9) located at the top of the coil ensures a blockage of the liquid in the case where it would arrive at this level; an air filter (8) makes it possible to filter the expansion air rising with each arrival of condensates before leaving the machine (10); a valve (7) open in the rest position Page 1 of 2 makes it possible to close the outlet orifice (6) when the cavity (2) is under pressure at each arrival of the condensates; a container (11) recovers the concentrated oil; a serpentine channel (5) is used to connect a bypass of hot compressed air taken from the compressor outlet which returns to the air circuit after returning the heat to our machine and thus causing its heating.

45 Dans la figure 1 il est représenté la machine en phase « arrivée sous pression des condensats » , ces derniers constitués d'eau à la base de la cavité remontent suite à la pression d'air comprimé arrivant en (4) , le mélange dans le serpentin constitué principalement d'eau commence a s'évaporer ; le clapet sous l'effet de la pression qui existe dans la cavité (2) 50 est fermé ; l'air s'échappe, en passant par le filtre (8) à travers l'orifice (10). In FIG. 1, the machine is shown in the "pressurized condensate inlet" phase, the latter consisting of water at the base of the cavity rise up again as a result of the pressure of compressed air arriving at (4), the mixture in the serpentine consisting mainly of water begins to evaporate; the valve under the effect of the pressure that exists in the cavity (2) 50 is closed; the air escapes through the filter (8) through the orifice (10).

Dans la figure 2 la machine est représentée pendant la phase « arrêt de l'arrivée des condensats « a ce moment les condensats redescendent du 55 serpentin (3) vers la cavité (2) , le niveau remonte dans la cavité et l'eau contenue dans les condensats s'évapore partiellement en redescendant du serpentin . In FIG. 2, the machine is shown during the phase "stop of the arrival of the condensates" at this moment the condensates descend from the coil (3) to the cavity (2), the level rises in the cavity and the water contained in the condensates evaporates partially down from the coil.

Le mélange eau/huile contenu dans la cavité (2) se concentre donc en 60 huile et s'accumule à la surface du liquide . The water / oil mixture contained in the cavity (2) is therefore concentrated in oil and accumulates on the surface of the liquid.

Dans la figure 3 la machine est représentée pendant la phase « repos du cycle «; il n'y a plus de pression d'air et tous le liquide est remonté dans la cavité (2) ; à ce moment le clapet (7) s'ouvre et le liquide constitué 65 en surface d'huile concentré s'évacue à travers l'orifice (6) et s'accumule dans le réservoir (11). Page 2 sur 2 In Figure 3 the machine is shown during the "rest phase of the cycle"; there is no more air pressure and all the liquid is raised in the cavity (2); at this moment the valve (7) opens and the liquid constituted 65 in the concentrated oil surface is evacuated through the orifice (6) and accumulates in the reservoir (11).
