Description

Technical Field

[0001] The present invention relates to providing, by mobile means, a variety of services related to the provision of hot water, water treatment, cleaning of pipes for the provision of drinking water or food liquids. Background Art

[0002] In the prior art, there are various devices and methods related to water treatment, cleaning pipes and providing hot water. Some of the documents proposing these solutions are described below.

[0003] Document EP 1 289 890 describes a device for metering reactants by dissolution in a liquid stream.

[0004] Document FR 2 946 622 describes a method for treating a drinking water circuit of an aircraft, a device and an aircraft making it possible to implement said method.

[0005] Document FR3011754 describes a treatment method for cleaning the pipes of an aircraft's drinking water network.

[0006] Document EP 2 718 033 describes a method for dynamically cleaning the water pipes of a vehicle and a device allowing the implementation of said method.

[0007] Document EP 3 055 080 describes a treatment method for cleaning the pipes of an aircraft's drinking water network.

[0008] Document EP3021989 describes a device for cleaning the pipes of an aircraft's drinking water network. This document describes in particular a device independent of the aircraft, which is occasionally connected to the network and supplied with liquid. This device comprises a number of functional elements necessary for producing hot liquid and a mobile chassis supporting a closed-furnace condensing gas boiler, which contains a number of gas cylinders providing a sufficient volume of gas capable of providing the energy necessary to produce a large amount of heat in a very short period of time. Summary of the invention

[0009] The applicant has conducted research aimed at using the last device described in the larger scope. This research has led to the design and creation of a mobile device that combines multiple functional subcomponents that not only implement the functions of the last device described in the larger scope but also realize the functions of other methods and devices.

[0010] In general, this mobile device of the invention provides services related to the provision of hot water, water treatment, cleaning of any fixed or mobile surface such as aircraft engines and pipes for the provision of drinking water or food liquids.

[0011] Therefore, the combination of the increase and / or oversizing of technical means for handling large volumes, in a single mobile device with volume and mass constraints, makes the features of the present invention solve new technical problems.

[0012] According to the invention, a device for services related to the provision of hot water, water treatment, cleaning of any fixed or mobile surface is remarkable because it is mobile and comprises: an internal chassis housing in the lower part a tank for recovering possible fluids, and a subassembly for producing hot water using at least one condensing boiler associated with at least one module for supplying gas formed by a plurality of gas storage tanks storing in their internal volume said gas in liquid state in said lower part and said gas in gaseous state in an upper part, said tanks being each equipped with a pipe for the passage of said gas, said pipe connecting said upper part containing said gas in said gaseous state to an opening orifice.

[0013] The extracted gas is therefore systematically in the gaseous phase. The presence of a carburetor and / or vaporizer is therefore no longer necessary, which avoids additional equipment between the boiler and the tank. The upper volume of the gas cylinder serves as an evaporation chamber.

[0014] This feature therefore avoids investments and saves volume and weight of the goods to be transported.

[0015] Also according to the invention, the device for services related to the provision of hot water, water treatment, cleaning of any fixed or mobile surface is excellent because it is mobile and comprises: an internal chassis housing in the lower part a tank for recovering possible fluids, and a subassembly for producing hot water using at least one condensing boiler associated with at least one module for supplying gas formed by a plurality of vaporizing type cylinders storing in their internal volume said gas in liquid state in said lower part and said gas in gaseous state in an upper part, said cylinders being placed substantially horizontally in said internal chassis with the opening orifice oriented upwards so that the end of the tube for the passage of said gas opens into a larger elongated gas-containing portion.

[0016] The presence of a chassis serves as an interface for positioning and keeping in place between the walls of the vehicle formed by the device and the functional subassembly. The chassis allows to house the cylinder according to an optimized orientation. The presence of a tank for recovering possible fluids avoids the accumulation of fluids in the volume.

[0017] The device of the invention comprises at least one inlet pipe and cable for connection to a source for supplying cold water and to a source for supplying electricity.The gas required for the boiler is stored in gas cylinders delivered by the device.

[0018] The device of the invention further comprises at least one outlet pipe allowing itself to be connected to an installation requiring its intervention, such as:

[0019] - Drinking water network on board aircraft, for example,

[0020] - Pipes of facilities through which food liquids circulate,

[0021] - Water network that requires hot water,

[0022] - any fixed or moving surface to be cleaned, such as aircraft engines,

[0023] -wait.

[0024] The advantage of this type of device is that it allows combining in the same mobile volume several functional subassemblies capable of implementing, in combination or not, several services related to the use of the above-mentioned facility.

[0025] The mobile device is a truck or van type vehicle equipped with a usable volume in which a chassis and various sub-assemblies on the chassis are placed.

[0026] The functional subassemblies accommodated on the chassis are, for example:

[0027] - a subassembly for producing hot water,

[0028] - subassemblies for handling liquids,

[0029] - Subassembly for metered injection of cold water,

[0030] -wait.

[0031] In order to produce a larger volume of hot water still in a very short time, the subassembly for producing hot water comprises a plurality of independent condensing gas boilers. This subassembly adds the facilities described in document EP3021989 in order to enhance its capacity.

[0032] According to a preferred but non-limiting embodiment, the subassembly groups together three separate identical boilers.

[0033] Adding a boiler to heat water from the same source and provide hot water to the same destination requires specific features.

[0034] Therefore, according to the present invention, the device includes pipes for the input of cold water and pipes for the output of hot water, and the order of supplying water to the boilers affected by the position of the boilers relative to the pipes for the input of cold water is opposite to the order of hot water output affected by the position of the boilers relative to the pipes for the output of hot water.

[0035] The functional subassembly for treating liquids is a subassembly for treating liquids by dissolving in the flow of the liquid a solid treatment product packaged in tablet form, stacked in a replaceable cartridge. According to the invention, this subassembly is excellent because the base into which the cartridge is inserted is equipped with a tank for recovering water that can leak during replacement of the cartridge.

[0036] This feature avoids spraying liquid from this subassembly into the available volume.

[0037] The subassembly for metering and injecting cold water includes a cold water metering pump, which injects the cold water into the outlet pipe of the device to adjust the flow rate and temperature.

[0038] The boiler obtains electricity by accessing the power grid. The device of the present invention includes a module for supplying electricity in addition to the module for supplying gas, and the module for supplying electricity is equipped with a member for controlling polarity, which verifies that the module for supplying electricity is compatible with the power supply of the boiler, and activates the rectifier if it is not compatible.

[0039] The basic concepts, further details and features of the invention, described above only in its most basic form, will become more apparent after reading the following description and referring to the accompanying drawings which are given as non-limiting example embodiments of the device according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] [ Figure 1 ] shows an example of a carrier for housing functional subassemblies of a device;

[0041] [ Figure 2 ] is a diagram showing various functional subcomponents of the device;

[0042] [ Figure 3 ] is a diagram of a cross-sectional view of a carburation gas cylinder. DETAILED DESCRIPTION

[0043] like Figure 1 As shown in the diagram of the drawings, the device generally designated D is a self-propelled mobile device, such as a truck or van, having a plurality of functional subassemblies necessary for providing the service of hot water, cleaning pipes for water or for food liquids in its rear portion or available volume.

[0044] The device D is moved to its site of use, for example an aircraft workshop, and its purpose is to clean the pipes forming the drinking water network of the aircraft.

[0045] The device D is equipped with a tube E for the input of a liquid and a tube S for the output of a liquid, the liquid having flowed through at least one of the functional subassemblies with which the device D is equipped.

[0046] As shown, the lower part of the available volume is occupied by a tank 100 for recovering fluid and a grille 110 placed on the tank 100. The upper part houses a chassis 120 for supporting various functional subassemblies. The upper wall of the truck is provided with openings 200 for gases to escape.

[0047] Figure 2 The diagram shows, starting from an inlet pipe E, the various functional subcomponents through which the drinking water network can flow coming from the point of use of the device.

[0048] This water can be treated according to the method and by means of the apparatus described in the above-mentioned prior art documents and / or for implementing the method described in said documents.

[0049] According to the present invention, the device D comprises:

[0050] - a subassembly 300 for producing hot water,

[0051] - a subassembly 400 for handling a liquid,

[0052] - Subassembly 500 for metered injection of cold water.

[0053] Upstream of these functional subassemblies, a universal pump 610 associated with a check valve 620 and a filtration module 630 moves and filters the water coming from inlet E.

[0054] These subassemblies may be operated simultaneously or individually, depending on the method to be implemented, and the three-way valve 700 or tap 800, either automatically or by an operator, allows selection between individual or simultaneous operation.

[0055] The subassembly 300 for producing hot water comprises three identical modules 300a, 300b, 300c for producing hot water, mounted in parallel starting from a pipe 640 which introduces water coming from a filtering module 630. According to the invention, these modules operate simultaneously but may be stopped for maintenance operations. Taps or valves allow isolating the modules.

[0056] Only module 300a is precisely described. This module 300a includes an exchanger 310a and a boiler 320a. As described above, the boiler is a closed furnace condensing gas boiler. Gas is provided by a module for supplying gas, which is marked as 330a. The module for supplying gas includes two vaporizing gas cylinders 331a and 332a with holes oriented upwards, which are horizontally arranged as described above. The gas from the gas cylinder passes through a membrane expansion valve 333a, then enters a flash tank 334a and passes through a flow regulator 335a, and is then supplied to the boiler 320a.

[0057] Judicious orientation of cylinders 331a and 332a allows the use of one of membrane expansion valve 333a and canister type 334a without the need for a carburetor. The water is heated at exchanger 310a.

[0058] like Figure 3 As shown for cylinder 331a, the upward orientation of the opening hole 301a of the 13 kg propane vaporizer cylinder shown in the figure allows the end 302a of the inner tube 303a to be systematically positioned to allow gas in a portion of the internal volume of the cylinder 331a to pass, which corresponds to the volume of the vapor space 304a rather than the liquefied gas 305a.

[0059] These cylinders are delivered in the installation D. The installation is therefore independent of the gas supply. The electricity supply is provided by insertion into the network but via an electricity supply module (not shown) equipped with means for verifying each phase so that it complies with the operation of the boiler. For the non-compliant phases, a rectifier (not shown) is used.

[0060] As shown, although identical, the modules 300a, 300b, and 300c are arranged in a specific order (from upstream to downstream) with respect to the supply flow from the cold water pipe 640. In order to avoid one module operating over another, the order defined by the position of the modules relative to the pipe 640 for cold water input is opposite to the order defined by the position of the modules (i.e., relative to the pipe for hot water output). Therefore, since the module 300a is first supplied with cold water by the pipe 640, the module 300b is second and the module 300c is third, the hot water from the module 300c corresponds to the pipe 650 for the outlet of hot water, into which the hot water from the more distant module 300b mixed with the hot water from the most distant module 300a is injected.

[0061] The subassembly 400 for treating water treats water coming from the inlet E and is equipped with at least one replaceable filter cartridge 410 containing the treatment product in tablets that dissolves under the action of moving water as described in various documents of the prior art. This filter cartridge 410 is removably fixed to a body 420 through which the water to be treated flows. According to the invention, this body is equipped around a hole in which the filter cartridge 410 is covered with a tank 430 for recovering the water that flows during the replacement of the filter cartridge 410.

[0062] The three-way valve 700 allows the use or non-use of this subassembly 400. The use of the three-way valve avoids using the treatment subassembly 400 and subassembly 300 together to produce hot water so that the chemical treatment is not neutralized by the hot water.

[0063] The subassembly 500 for metering the injection of cold water uses water from inlet E and includes a metering pump 510 arranged downstream of the pressure relief valve 520 and the faucet 800 so as to inject cold water into the outlet pipe of the device, thereby adjusting the volume of treated water, the flow rate and temperature of water from other functional subassemblies when necessary.

[0064] It should be understood that the above only describes and shows the device for the purpose of disclosure and not limitation and describes and shows with the drawings. Of course, various arrangements, modifications and improvements can be made to the above examples without exceeding the context of the present invention.
