[0052] FIG. 2 is a diagram illustrating the various functional subassemblies of the device;

[0053] FIG. 3 is a diagram of a cross-sectional view of a carburation gas cylinder.

DESCRIPTION OF AN EMBODIMENT

[0054] As illustrated in the drawing of FIG. 1, the device labelled as D overall is a self-propelled mobile device such as a truck or a van that houses in its rear part or useful volume a plurality of functional subassemblies necessary for services of providing hot water, of cleaning ducts for water or for food liquid.

[0055] This device D moves on its site of use like an aircraft workshop for purposes of cleaning the ducts forming the potable-water network of an airplane.

[0056] The device D is equipped with a duct E for inlet of liquid and with a duct S for outlet of the liquid that has passed through at least one of the functional subassemblies with which the device D is equipped.

[0057] As illustrated, the lower part of the useful volume is occupied by a tank 100 for recovering the fluids and by a grating 110 disposed on the tank 100. The upper portion houses a chassis 120 for supporting the various functional subassemblies. The upper wall of the truck is provided with openings 200 to let the gases escape.

[0058] The schema of FIG. 2 illustrates, starting from the inlet duct E, the various functional subassemblies through which the water that can come from the potable-water network of the site of use of the device can pass. Water can also come from a tank mobile or not.

[0059] This water can be treated according to the methods and by the devices described in the documents of the prior art cited above and/or for implementing the methods described in said documents.

[0060] According to the invention, the device D comprises: [0061] a subassembly 300 for producing hot water, [0062] a subassembly 400 for treating liquid, [0063] a subassembly 500 for metered injection of cold water, [0064] a pre-treatment subassembly 900 for treating water before its heating.

[0065] Upstream of these functional subassemblies, a general pump 610 associated with a check valve 620 and with a filtration module 630 move and filter the water coming from the inlet E.

[0066] These subassemblies can operate simultaneously or separately according to the method to be implemented, three-way valves 700 or faucets 800 actuated automatically or by an operator allow to select between separate or simultaneous operations.

[0067] The subassembly 300 for producing hot water comprises three identical modules 300a, 300b, 300c for producing hot water mounted in parallel starting from a duct 640 bringing the water coming from the filtration module 630. According to the invention, these modules operate simultaneously but can be the subject of a stoppage for purposes of maintenance operations. Faucets or valves allow to isolate the modules.

[0068] Only the module 300a is precisely described. This module 300a comprises an exchanger 310a and a boiler 320a. As described above, this is a closed-furnace condensing gas boiler. The gas is provided by a module for supplying gas labelled as 330a. The module for supplying gas comprises two cylinders 331a and 332a of the carburation type disposed as described above horizontally with orifices oriented upwards. The gas coming from the cylinders passes through a membrane expansion valve 333a then into a flash tank 334a and through a flow regulator 335a before supplying the boiler 320a.

[0069] The judicious orientation of the cylinders 331a and 332a allows the use of a membrane expansion valve 333a and one of the tank type 334a without requiring a carburetor. The water becomes hot at the exchanger 310a.

[0070] As illustrated by FIG. 3 for the cylinder 331a, the upwards orientation of the opening orifice 301a of a carburation gas cylinder of 13 kg of propane like that illustrated allows to systematically dispose the end 302a of the internal pipe 303a for passage of gas in the part of the internal volume of the cylinder 331a corresponding to the vapor space 304a and not to the volume of liquefied gas 305a.

[0071] These cylinders are transported in the device D. The device is thus independent with regard to the supply of gas. The supply of electricity is provided by plugging into the network but via a power supply module (not shown) equipped with a device for verifying the phases in order for it to be compliant with the operation of the boilers. In the case of a non-compliant phase, a rectifier (not shown) is used.

[0072] As illustrated, although identical, the modules 300a, 300b and 300c are disposed in a certain order (from upstream to downstream) with respect to the supply flow coming from the cold-water duct 640. In order to avoid a module operating more than another, the order defined by the position of the module with regard to the duct 640 for inlet of cold water is inversed with respect to the order defined by the position of the module (that is to say with regard to the duct for outlet of hot water). Thus, since the module 300a is the first supplied with cold water by the duct 640, the module 300b being supplied second and the module 300c third, the hot water coming from the module 300c corresponds to the duct 650 for outlet of hot water into which the hot water coming from the farther module 300b mixed with the hot water coming from the farthest module 300a is injected.

[0073] The subassembly 400 for treatment of the water treats the water coming from the inlet E and is equipped with at least one interchangeable cartridge 410 containing treatment products in tablets dissolving under the action of the moving water as described in a plurality of the documents of the prior art. This cartridge 410 is removably fastened onto a body 420 through which the water to be treated passes. According to the invention, this body is equipped around the orifice in which the cartridge 410 is housed with a tank 430 for recovering the water that flows during the changing of the cartridge 410.

[0074] The three-way valves 700 allow to use or not use this subassembly 400. The use of three-way valves avoids the use of the treatment subassembly 400 with the subassembly 300 for producing hot water in order for the chemical treatment to not be neutralized by the hot water.

[0075] The subassembly 500 for metered injection of cold water uses the water coming from the inlet E and comprises a metering pump 510 disposed downstream of a pressure-relief valve 520 and of the faucet 800 in order to inject, into the outlet duct of the device, the cold water to regulate if necessary the volume of water treated, the flow and the temperature of the water coming from the other functional subassemblies.

[0076] The pre-treatment subassembly 900 treats the water which has been filtered by the filtration module 630. It uses at least one of the technologies listed below: [0077] adding water softener, [0078] using reverse osmosis technology.

[0079] The subassembly 900 further comprises a tank 910 receiving the different fluids coming from the implementation of the pre-treatment technologies.

[0080] It is understood that the device that has just been described and shown above has been described and shown with a view to disclosure rather than limitation. Of course, various arrangements, modifications and improvements can be made to the above examples without going beyond the context of the invention.
