Abstract

The present method relates to a system of cleaning walls, statues, woodwork, stones, stately buildings, archaeological remains and all outdoor covering materials, by rubbing. The method is characterised by the joint use of a mixture of a granular powder with compressed air. This mixture is propelled by very-low-pressure water. The assembly forms a complete system consisting of an air compressor (1), an air cooler (3), a pressure reservoir (2), a high-pressure water propulsion unit (13) and a gun (11) for propelling the mixture onto the surface to be treated and for rinsing this surface down. The mixture of air and granular material is propelled by the pressure of the water transmitted by the high-pressure propulsion unit (13) and mixed inside the gun (11) with the mixture of air and granular material. This gun comprises a cleaning nozzle (25) which works on the support to be cleaned with a rubbing action. This gun throws onto the support a mixture of air and very fine neutral granular material propelled by the water at a pressure of 1.5 to 0.5 bar. This system consumes only 30 litres of water per hour and completely safeguards the structure and the properties of the cleaned support. It is also harmless to the environment.

Ce procédé utilise un ensemble constitué d'un compresseur d'air, d'un refroidisseur d'air, d'un réservoir de pression, aun propulseur d'eau à haute pression et d'un pistolet assurant la propulsion du mélange sur la surface à traiter et le rinçage de cette surfaçe. This process uses an assembly consisting of an air compressor, an air cooler, a pressure tank, a high pressure water propellant and a gun ensuring the propulsion of the mixture on the surface to be treated and the rinsing of this surface.

La propulsion du mélange air-granulat s'effectue à partir de la pression de l'eau transmise par le propulseur à haute pression et mélangé dans le pistolet au mélange air-granulats
Les dessins annexés illustrent le procédé: - La Figure 1, sur la planche 112, représente l'ensemble du procédé en fonctionnement - La Figure 2, sur la planche 212, représente, en coupe, I'ensemble pistolet avec la buse
permettant lemélange eaulairlgranulats et les règlages de pression.The air-aggregate mixture is propelled from the pressure of the water transmitted by the high-pressure propellant and mixed in the gun with the air-aggregate mixture
The accompanying drawings illustrate the process: - Figure 1, on board 112, represents the entire process in operation - Figure 2, on board 212, shows, in section, the gun assembly with the nozzle
allowing mixing of aggregates and pressure settings.

Le compresseur (1) foumit l'air necéssaire à la propulsion des granulats contenus dans le reservoir de pression (2) qui content ces granulats. La pression à la sortie du compresseur doit être de 8 bars et le débit d'air de 2400 litresiminute. The compressor (1) supplies the air necessary for the propulsion of the aggregates contained in the pressure tank (2) which contains these aggregates. The pressure at the outlet of the compressor must be 8 bars and the air flow by 2400 liters decreases.

En sortie du compresseur(1), un refroidisseur d'air(3) est connecté a ce compresseur par un tuyau(4). Ce refroidisseur a pour fonction de libérer au maximum l'air comprimé de la condensation d'eau et porter cet air comprimé à la température ambiante afin d'éviter la formation de condensation dans le réservoir de pression(2) contenant les granulats.At the outlet of the compressor (1), an air cooler (3) is connected to this compressor by a pipe (4). This cooler has the function of freeing the compressed air as much as possible from the condensation of water and bringing this compressed air to room temperature in order to avoid the formation of condensation in the pressure tank (2) containing the aggregates.

Ce refroidisseur est branché sur le réseau électrique 220V (5).This cooler is connected to the 220V electrical network (5).

La sortie du refroidisseur est connectée à un détendeur(6) équipé d'un manomètre(7) par un tuyau(8). The outlet of the cooler is connected to a pressure reducer (6) equipped with a pressure gauge (7) by a pipe (8).

Une télécommande pneumatique permet l'arrêt du système. Cette télécommande est activée à partir d'une commande électrique(9) située sur le pistolet(1 1) et commandé par une électro vanne(1 0) située sur le réservoir de pression(2).A pneumatic remote control stops the system. This remote control is activated from an electrical control (9) located on the gun (1 1) and controlled by a solenoid valve (1 0) located on the pressure tank (2).

Le mélange airlgranulat s'effectue dans le réservoir de pression(2). Ce réservoir est connecté à un pistolet(11) par un tuyau(12)
La pression du mélange airlgranulat au niveau de l'arrivée au pistolet(1 1) est de 4 bars
L'eau sous pression necéssaire à la propulsion du mélange airlgranulats sur la surface à traiter(31) est obtenue par l'utilisation d'un appareil à haute pression(13) alimenté en eau par le tuyau(14) et fonctionnant sur le réseau électrique 220V(15)
Cet appareil fournit l'eau sous une pression de 60 bars au pistolet(11) par un tuyau(16).The air-aggregate mixture takes place in the pressure tank (2). This tank is connected to a gun (11) by a hose (12)
The pressure of the airlgranulate mixture at the level of the gun inlet (1 1) is 4 bars
The pressurized water necessary for propelling the airlgranulate mixture on the surface to be treated (31) is obtained by the use of a high pressure device (13) supplied with water by the pipe (14) and operating on the network. electric 220V (15)
This device supplies water at a pressure of 60 bars to the gun (11) through a pipe (16).

La commande générale d'arrivée d'eau sous pression dans le pistolet(11) est assuré par la commande(17)
Le nettoyage de la surface à traiter(31) est assuré par le pistolet(1 1)
Ce pistolet comporte 2 circuits:
- un circuit de traitement de la surface à nettoyer
- Un circuit de rinçage
Ce pistolet est constitué d'un carter(18) renfermant tous les éléments de traitement. Ce carter s'ouvre en 2 parties, dans le sens longitudinal, afin d'accéder à tous les éléments constituant le pistolet
L'eau arrive dans le pistolet par le tuyau(1 9) sous une pression de 60 bars. Une commande (17) permet de doser ou d'interrompre l'arrivée de l'eau par action sur la vanne(20).The general control of pressure water inlet in the gun (11) is ensured by the control (17)
The surface to be treated (31) is cleaned by the spray gun (1 1)
This gun has 2 circuits:
- a circuit for treating the surface to be cleaned
- A rinsing circuit
This gun consists of a housing (18) containing all the processing elements. This housing opens in 2 parts, in the longitudinal direction, in order to access all the elements constituting the gun
Water enters the gun through the hose (1 9) under a pressure of 60 bars. A control (17) makes it possible to dose or interrupt the arrival of water by action on the valve (20).

L'eau parvient ensuite dans un ensemble dérivateur(21).Cet ensemble pennet sur une voie le rinçage de la surface nettoyée(31). Ce rinçage est exécuté par la buse de micropulvérisation (22) commandée par la mini-vanne de réglage(23).The water then arrives in a diverter assembly (21). This assembly allows on one channel the rinsing of the cleaned surface (31). This rinsing is carried out by the micropulverization nozzle (22) controlled by the mini adjustment valve (23).

Sur l'autre voie de l'ensemble dérivateur(21), une autre mini-vanne(24) permet le réglage fin de la pression d'eau dans la buse de nettoyage(25). L'eau pénètre alors à une pression comprise entre 1,5 et 0,5 bars, par l'intermédiaire d'un orifice injecteur(26), dans une chambre de mélange(27).On the other track of the diverter assembly (21), another mini-valve (24) allows fine adjustment of the water pressure in the cleaning nozzle (25). The water then enters at a pressure of between 1.5 and 0.5 bars, via an injector orifice (26), into a mixing chamber (27).

Le mélange airlgranulats arrive dans le pistolet(11) par le tuyau(28) et est injecté dans la chambre de mélange(27) par un injecteur(29). Cet injecteur est incliné de 30 par rapport à l'axe longitudinal de la chambre de mélange(27).The airgranulate mixture arrives in the gun (11) through the pipe (28) and is injected into the mixing chamber (27) by an injector (29). This injector is inclined by 30 relative to the longitudinal axis of the mixing chamber (27).

Ce mélange aidgranulats est mélangé à l'eau dans la chambre de mélange(27) et est propulsé dans la buse(25) sous forme cyclonique du fait de l'entrée conique de la buse(30) et de l'inclinaison de l'axe de l'injecteur du mélange airlgranulats(29) par rapport à l'axe de projection de l'eau.This aidgranulate mixture is mixed with water in the mixing chamber (27) and is propelled into the nozzle (25) in cyclonic form due to the conical entry of the nozzle (30) and the inclination of the axis of the airlgranulats mixture injector (29) relative to the axis of water projection.

La pression de sortie, donc de travail sur la surface à nettoyer, est comprise entre 1,5 et 0,5 bars.The outlet pressure, therefore working pressure on the surface to be cleaned, is between 1.5 and 0.5 bars.

Le nettoyage s'effectue par gommage léger horizontal et non par projection d'un jet perpendiculaire à la surface à traiter(31). The cleaning is carried out by light horizontal scrub and not by spraying a jet perpendicular to the surface to be treated (31).

L'eau de rinçage ne contenant aucun procédé chimique peut être rejeté directement à l'dégoût sans filtrage spécifique et la pression de travail étant trés basse l'instaliation de chantier est très légère et ne provoque pas de nuisances.The rinsing water containing no chemical process can be discharged directly to the drain without specific filtering and the working pressure being very low the installation of site is very light and does not cause any nuisance.

Le procédé est particulièrement destiné au nettoyage des bâtiments, des monuments, des statues, du patrimoine historique et archéologique, à la suppression des graffitis. The process is particularly intended for cleaning buildings, monuments, statues, historical and archaeological heritage, removing graffiti.
