Description

Title of the invention: Effluent recovery installation by suction and its management method

[0001] The present invention relates to an effluent recovery installation by suction and its management method.

[0002] It is particularly applicable to sites where several effluent production units are likely to be installed that cannot be connected to a gravity-flow sewage system. This is especially the case for boats moored in ports or on motorhome service areas, or even on campsites.

[0003] Various solutions for collecting wastewater from boats, particularly pleasure craft of a certain size, already exist in ports.

[0004] For example, a collective collection facility may be located at a dedicated quay where boats dock each time they need to empty their effluent collection tanks. Even if some vessels rarely go to sea, they must start their engines to leave their mooring quay and dock at the collective effluent collection quay for each of these emptying operations.

[0005] An alternative solution to the previous one consists of a specific collection boat moving in the port and collecting on demand the effluents from pleasure boats directly at their mooring quay.

[0006] Some ports include vacuum effluent recovery facilities comprising, essentially: • a recovery tank for these effluents maintained under negative pressure by means of a vacuum pump; • a main pipe emptying, at its downstream end, into the recovery tank; • a network of connecting pipelines linking several boats directly to the main pipeline or via secondary pipelines.

[0007] The operating principle of such installations consists of creating a relative vacuum in the effluent recovery tank with the aim of drawing the effluents into the different pipes at each effluent input at the level of a boat.

[0008] Thus, when an effluent is brought in from a boat into the connecting pipe to which it is connected, a suction corresponding to the volume of effluent brought in is created in this connecting pipe, but also in the main pipe.

[0009] Consequently, the effluents in each of the pipelines progress according to the upstream effluent input, at the level of a ship. As this input occurs discontinuously, the progression of these effluents in the various pipelines is itself discontinuous.

[0010] It is understood that the level of vacuum created in the effluent recovery tank by means of the vacuum pump must be sufficient to ensure the suction of effluents from at least one boat to the effluent recovery tank.

[0011] In reality, since the supply of effluent at the level of several boats can occur simultaneously, it is necessary to oversize the vacuum pump and / or the vacuum volume in the recovery tank so as to be able to suck up almost instantaneously a volume of effluent much larger than that which can be delivered by a single boat.

[0012] Moreover, effluent inputs depend on the occupancy rate of the boats. This occupancy rate can be almost zero off-season and, conversely, very high during the season. While a low-power vacuum pump would be able to easily handle all situations during periods of low occupancy, it must necessarily be sized to meet the constraints arising from 100% occupancy.

[0013] In this context, it should be taken into account that by excessively increasing the negative pressure created by the vacuum pump, the pipes, often of a flexible type, are likely to collapse.

[0014] Finally, although effective, these vacuum effluent recovery systems under negative pressure are certainly efficient, but also present numerous disadvantages: • they do not have an automatic operating management system; • they do not have an advanced alert and monitoring system; • their processing capacity is defined by the manufacturer and cannot evolve without modifying or changing the performance of the vacuum pumps; • They are sensitive to variations in hourly flow and can quickly reach limited capacity.

[0015] Some ports are completely devoid of means of recovering the effluents from these pleasure boats, which then have no other solution than to empty them at sea in accordance with the regulations.

[0016] Despite the monitoring measures implemented, the tendency to discharge waste at a shorter distance, along the coastline, remains strong. In any case, these discharges at sea, even in regulated areas, are a source of pollution and contrary to current environmental protection efforts.

[0017] In view of the above, there is a need for an effluent collection point at each of the boat mooring points along a quay or floating pontoon, with the possibility of conveying these effluents towards a dedicated wastewater treatment plant or an urban collective sanitation network.

[0018] Furthermore, once a boat is connected to a collection point, the emptying of the contents of its effluent storage tank must take place in an automated manner, following a predetermined emptying sequence at the different collection points or, alternatively, at will, following a controlled sequence.

[0019] To this end, the invention relates to an effluent recovery installation by suction from at least one effluent production unit, such as a boat, a motorhome or similar, comprising: • at least one suction station equipped with pumping equipment, • at least one main pipeline to which is connected, directly or indirectly via a secondary pipeline, at least one effluent collection point; characterized in that the effluent collection point is connected directly or indirectly to said main pipeline via a motorized valve to which is associated opening and closing control electronics connected by wire or wireless means to at least one main management unit comprising a data recording memory, said collection point having first means of connection for receiving second means of connection from a proprietary pipeline comprising an effluent production unit

[0020] According to the invention, this installation further comprises, emptying control means associated with each of the collection terminals.

[0021] Advantageously, each collection terminal includes retractable closing means comprising second connection means capable of cooperating with the first connection means.

[0022] The invention further relates to a method for managing such an installation, comprising N collection terminals, characterized in that: • the N collection terminals are recorded in a specific order in the memory of the main management unit; • A drainage sequence is initiated via the main management unit by executing a drainage cycle, successively and in the order recorded, at each of the collection points. This involves, via the electronic control of the motorized valve at each collection point, commanding the opening of the motorized valve, followed by the phase effluent drainage by means of pumping and closing of said motorized valve.

[0023] The process also provides, as an option: • to record in the memory of the main management unit a frequency for the execution of the emptying sequence over a determined time range; • to measure the flow rate of effluent aspirated during a draining cycle; • to measure the pressure continuously or discontinuously at least in the main pipeline; • to detect the absence of secondary means of connection of a proprietary pipeline or of a plug on the first means of connection of a collection terminal before a drainage cycle; • to detect the absence of effluent flow or an effluent flow below a threshold value during a draining cycle; • to define the frequency of emptying sequences according to the occupancy rate of the effluent production units connected to the installation; • to interrupt a draining sequence in the event of an automatic and / or manual emergency stop command.

[0024] Other objects and advantages of the present invention will become apparent from the detailed description below, this description being supplemented by the accompanying figures given by way of illustration and not limitation, among which:

[0025] [Fig-1] The [Fig.1] is a schematic diagram of the installation according to the invention.

[0026] The effluent recovery installation 1 by suction essentially comprises a suction station 2 equipped with pumping means 3. These can take the form of one or more vacuum pumps defined according to the needs, in particular the size of the installation.

[0027] At least one main pipe 4 is connected to this suction station 2, to which is connected, in particular via a connecting T 5, either directly or via a secondary pipe 6, at least one collection terminal 7b 72, 73, 74. More precisely, this is connected to this secondary pipe 6 or, as the case may be, directly to the main pipe 4 via a motorized valve 8. Associated with this valve is an electronic control unit 9 for opening and closing, linked to a main control unit 10.

[0028] If on each secondary pipe 6 of the single attached figure only one collection terminal 7b 72, 73, 74 is connected, the invention is not limited to such a configuration and a secondary pipe 6 is able to connect several of these collection terminals to the main pipe 4.

[0029] A collection terminal 7b 72, 73, 74 also includes first means of connection for receiving second means of connection which includes a proprietary pipeline which includes an effluent production unit 1 la, 11b, 11c, lld.

[0030] In the example described below, these effluent production units 1 la, 11b, 1 le, 1 Id are considered to be boats moored alongside a quay, a floating or fixed pontoon... Thus, at each location provided on this quay or pontoon, a collection terminal 7b 72, 73, 74 is installed. A boat, in this case its effluent recovery tank, can be connected to the first connection means of such a collection terminal 7b 72, 73, 74, by means of second connection means equipping a proprietary pipeline 12a, 12b, 12c, 12d.

[0031] These first and second means of connection can take different forms, for example that of fire hose couplings, also called symmetrical or Guillemin couplings. They can also be in the form of screw couplings, quick push-fit couplings, cam couplings, etc.

[0032] Advantageously, each collection point 7b 72, 73, 74 is equipped with a plug capable of replacing the secondary connection means of a proprietary pipeline 12a, 12b, 12c, 12d when the latter is disconnected from the collection point 7b 72, 73, 74. Preferably, this plug is secured to a collection point 7b 72, 73, 74 by means of a flexible connection, such as a cable or chain, preventing it from inadvertently falling into the water or being lost in any other way once removed from the primary connection means of said point 7b 72, 73, 74. This systematic presence of the plug on the collection point 7b 72, 73, 74 also serves as a reminder of the obligation to close this collection point. 7b 72, 73, 74 via this obturator once the proprietary pipe 12a, 12b, 12c, 12d is disconnected.

[0033] By ensuring, in this way, the systematic sealing of a collection point 7b 72, 73, 74, whether through such a seal or a proprietary pipe 12a, 12b, 12c, 12d, any risk of accident or suction of any object likely to obstruct the pipes downstream is avoided.

[0034] Optionally, a collection point 7b 72, 73, 74 may be equipped with means for detecting the absence of a plug and / or secondary means for connecting a proprietary conduit 12a, 12b, 12c, 12d to the first means for connecting said collection point 7b 72, 73, 74. These detection means are advantageously designed to activate visual and / or audible signaling means and / or to send information to the main control unit 10 preventing the ordering a drainage cycle through the relevant collection terminal 7b 72, 73, 74, as will be explained in more detail in the description that follows.

[0035] Such detection means can take various forms, for example, a switch placed on or near the first connection means of a collection terminal 71, 72, 73, 74, a switch which is activated as long as the second connection means of the shutter are not positioned on these first connection means. This switch can itself be of a mechanical or electronic type.

[0036] Thus, through a proprietary pipeline 12a, 12b, 12c, 12d, or even a secondary pipeline 6 and a main pipeline 4, passing through a collection terminal 7b 72, 73, 74 and a motorized valve 8 connecting the latter directly or indirectly to the main pipeline 4, the effluents from a production unit 1la, 11b, 1le, 1Id, in this case from a boat, are likely to be pumped by suction by the pumping means 3 towards the suction station 2.

[0037] These effluents can then be discharged through this same pumping station 2, as appropriate, into a collective sanitation network 13 or into a dedicated treatment station.

[0038] The pumping means 3 of the suction station 2 can further send these effluents into a discharge buffer tank 14, from which they are then drawn for discharge into this collective sewer system 13 or towards this dedicated treatment plant. The advantage of this second solution lies in the controlled delivery of these effluents to this collective sewer system 13 or to this dedicated treatment plant. Another advantage is that polluted effluents, for example those containing hydrocarbons, can be treated before entering the collective sewer system 13 or the dedicated treatment plant.

[0039] According to the method of implementing this effluent recovery installation 1 by suction, the suction of effluents from production units lia, 11b, 11c, 1 Id is selectively controlled one after the other according to a determined sequence.

[0040] More precisely, in a first step, a drainage cycle is commanded via the main control unit 10 and the control electronics 9 of the motorized valve 8 of a first collection point 71 of a set of N collection points, corresponding to the opening of the motorized valve 8 of this first point 7b followed by the suction phase of the effluents by the pumping means 3, and then the closing of said motorized valve 8 of said first point 7b.

[0041] In particular, it can be determined in different ways that all of the effluent has been aspirated, for example by means of a flow sensor associated with each of the collection terminals 7b 72, 73, 74 and / or placed on the secondary pipe 6 to which this terminal is connected and / or on the main pipe 4 and / or at the suction station 2. Another solution consists of detecting a variation in the suction pressure, in this case a decrease in this suction pressure over a determined period of time.

[0042] In a subsequent step, a drainage cycle corresponding, again, to the opening of the motorized valve 8 of this second collection terminal 72, followed by the phase of suction of the effluents by the pumping means 3, and then the closing of said motorized valve 8 of said second terminal 72, is reproduced through the main management unit 10 and the control electronics 9 of the motorized valve 8 of said second terminal 72.

[0043] In an installation comprising N collection terminals, a cycle of emptying each of the following collection terminals up to the Nth terminal is carried out in the following steps and successively in a predefined order, through the main management unit 10 and the control electronics 9 of the motorized valve 8 of these collection terminals 73 to 7N.

[0044] Advantageously, the order of the collection terminals (from the first to the Nth) in which the emptying cycles are carried out successively is recorded in a memory of the main management unit 10, in the form of an emptying sequence.

[0045] Thus, during the execution of an emptying sequence, an emptying cycle is successively commanded through each of the collection terminals 7i, 72, 73, 74 in this predefined order. This sequence can then be repeated at a frequency and / or within one or more predefined and recorded time ranges, for example in a memory of the main management unit 10. However, this frequency and / or these time ranges are preferably adjustable using a control screen on this central management unit 10 or by means of a USB key or equivalent, or even via a remote processing unit 15 to which this main management unit 10 is connected by means of suitable intercommunication means.

[0046] In particular, the frequency of the emptying sequences can be determined as a function of the occupancy rate of the effluent production units lia, 11b, 11c, 1 Id.

[0047] To return to the order in which the emptying cycles take place through the collection points 7b 72, 73, 74, this order may correspond to a numbering of these points and / or to an order of installation along quays or pontoons and / or to a decreasing or increasing volume of the effluent tanks of the production units lia, 11b, 1 le, 1 Id and / or to a connection order of these production units 1 la, 11b, 1 le, 1 Id to their collection terminal 7b 72, 73, 74respective, etc.

[0048] The order of the emptying cycles during an emptying sequence can also be determined based on the volumes of effluent drawn from each of the collection points during one or more previous sequences. Since the emptying occurs sequentially and successively, this volume of effluent drawn from a collection point 7b 72, 73, 74 can be measured directly by a suitable measuring device, such as a flow sensor. As already explained, such a flow sensor can be placed at each of the collection points 7b 72, 73, 74 and / or on the secondary pipe 6 and / or on the main pipe 4 connecting such a collection point 7b 72, 73, 74 to the suction station 2 and / or at this suction station 2.

[0049] Thus, if zero or near-zero effluent suction is detected through a given collection terminal 7b 72, 73, 74 during one or more previous sequences, this terminal 7b 72, 73, 74 is excluded from one or more subsequent emptying sequences, or even until a manual command for an emptying cycle is identified, as explained further in this description

[0050] Note that a collection terminal 7b 72, 73, 74 can be excluded from a drainage cycle by programming and / or in case of detection of failure of the motorized valve 8 and / or of its control electronics 9 for example and / or in case of detection of absence of the second means of connection corresponding to a shutter and / or of a proprietary pipe 12a, 12b, 12c, 12d on the first means of connection of said collection terminal 7b 72, 73, 74.

[0051] According to the invention, the installation 1 further includes automatic and / or manual emergency stop control means 15. In particular, this emergency stop control 15 may be in the form of at least one push-button type switch, located on or near the suction station 2 and / or on all or part of the collection points 7b 72, 73, 74 and / or near them, for example on a quay or pontoon.

[0052] Such emergency stop control means 15 can also take the form of hydrocarbon detection means equipping each of the collection terminals 7b 72, 73, 74 and / or one of the pipelines 4, 6 connecting these to the suction station 2 and / or on the pipeline possibly connecting the suction station 2 to a discharge buffer tank 14 into which the effluents from the emptying cycles are discharged.

[0053] Here again, insofar as, during a draining sequence, the draining cycles are carried out successively and sequentially, the terminal can be identified Collection points 7b 72, 73, 74, from which these hydrocarbons, detected by appropriate means, originate. This collection point 7b 72, 73, 74 can then be excluded from subsequent emptying sequences until manually reprogrammed at the main management unit 10 or the remote treatment unit 15.

[0054] According to the invention, this installation 1 further comprises manual drain control means 16 associated with each of the collection points. 7b 72, 73, 74 Such manual drain control means 16 may take the form of a simple control button placed on a collection point 7b 72, 73, 74, for example on the housing containing the control electronics 9 of the motorized valve 8. These control means 16 may also be in the form of a key switch, a keypad, an optical reader, a magnetic card reader, or even an RFID card reader.

[0055] The advantage of manual emptying control means 16 of the secure type, with key, code or other reader, is that only the holder of the key, code or suitable card is able to manually trigger an emptying cycle of the effluent production unit 1 la, 11b, 1 le, 1 Id connected to the collection terminal 7b 72, 73, 74d from which the emptying command is issued.

[0056] This manually controlled drain cycle can occur immediately after receipt, by the main management unit 10, of said manual drain command, just as it can be recorded to occur as a priority at the beginning of a new upcoming drain sequence and / or, if this command is issued outside a pre-programmed time slot allowing the execution of drain cycles, at the beginning of the next dedicated time slot.

[0057] If a manual drain command is generated during a drain sequence, the sequence can be interrupted to prioritize the drain cycle corresponding to the collection point 7b 72, 73, 74 from which the manual drain command was issued. Once this drain cycle is complete, the drain sequence resumes from the next collection point 7b 72, 73, 74 relative to the one where the sequence stopped, according to the predefined execution order of this drain sequence.

[0058] According to one possible variant, when a manual emptying command is issued from a collection terminal 7b 72, 73, 74 during an emptying sequence in which the emptying cycle of the collection terminal in question must necessarily be included, the emptying cycle of the latter occurs in the order of execution of the emptying sequence.

[0059] According to the invention, the main management unit 10 is further connected, either wired or wirelessly, particularly via an Internet network, to a unit of Remote data processing unit 15. For example, all information relating to the emptying sequences carried out by the main control unit 10 can be sent to this remote processing unit 15, in particular any malfunctions of a motorized valve 8 or associated control electronics 9 in relation to a collection terminal 71, 72, 73, 74, where applicable, collection flow rates, information (date and time) of manual emptying commands, etc. A smartphone application may be provided to monitor the entire installation 1.

[0060] It may be provided that the programming of the main management unit 10 can be carried out through this remote processing unit 15, in particular with regard to the frequencies of the emptying sequences and / or the time slots during which these emptying sequences and / or a manual emptying command can be executed.

[0061] It should be noted in this regard that the frequency of the emptying sequences depends on: • flow rates of aspirated effluent; • and / or the order of the emptying cycles through the collection terminals 7b 72, 73, 74; • and / or the occupancy rate, taking into account, as appropriate, the history of previous sequences and / or the collection terminals 7b 72, 73, 74 detected as blocked; can be determined by this remote processing unit 15, then addressed to the main management unit 10 for the execution of the following sequences.

[0062] As already indicated above, with the help of this remote processing unit 15 it can be made possible to program the time period, or time periods during which the emptying sequences or simply an emptying cycle can take place manually from a collection terminal 7b 72, 73, 74. As an example, these time periods can be chosen during the day so that the noise possibly generated during the emptying cycles disturbs as little as possible the occupants of the effluent production units lia, 11b, 11c, 1 Id, in this case boats.

[0063] It is possible that one or the other pipe 4, 6 may become blocked, which can be detected by a draining of the effluent tank of at least one of the production units 11a, 11b, 11c, 11d which is no longer operating. In this case, the method, according to the invention, may provide for carrying out a specific draining sequence to detect pipe blockage. Such a specific sequence may be initiated manually, as appropriate, from the main control unit 10 or the remote treatment unit 15 by an authorized person. Such a specific sequence The system successively commands a drainage cycle through each of the N collection points 7b, 72, 73, 74, in a predefined order, in order to detect, notably using at least one flow sensor, the collection point(s) 7i, 72, 73, 74 and / or the pipe(s) 4, 6 through which no effluent is collected or whose flow rate is below a threshold value, indicating a flow problem. This information allows the affected pipe(s) 4, 6, or even the collection point(s) 7b, 72, 73, 74, to be isolated for maintenance or repair.

[0064] In summary, the installation management method according to the invention comprises the following steps taken individually or in combination: • the N collection terminals 7b 72, 73, 74 are recorded in a determined order in the memory of the main management unit 10; • a drainage sequence is ordered through the main management unit 10 by executing a drainage cycle, successively and in the order of recording, at each of the collection terminals consisting, via the control electronics 9 of the motorized valve 8 of each of the collection terminals 7b 72, 73, 74, of ordering the opening of the motorized valve 8, followed by the phase of suction of the effluents by the pumping means 3 and the closing of said motorized valve 8, of each of these collection terminals 7b 72, 73, 74; • The frequency of execution of the emptying sequences over one or more determined time periods is recorded in the memory of the main management unit 10; • during a draining cycle, the flow rate of effluent aspirated is measured; • Before a drain cycle, the absence of backup means is detected connection of a proprietary pipeline or of a shutter on the first means of connection of a collection terminal 7b 72, 73, 74; • during a draining cycle, the absence of effluent flow or an effluent flow lower than a threshold value is detected; • A drain cycle of a collection point 7b 72, 73, 74 is interrupted if the absence of secondary connection means for a proprietary pipe 12a, 12b, 12c, 12d or of a shut-off valve on the primary connection means is detected, and / or there is no effluent flow or an effluent flow rate below a threshold value, and / or a collection point 7b 72, 73, 74 is excluded from the drain sequence if the absence of secondary connection means for a proprietary pipe 12a, 12b, 12c, 12d or of a shut-off valve on the primary connection means is detected, and / or there is no effluent flow or an effluent flow rate below a threshold value. effluent flow rate or an effluent flow rate below a threshold value or during the previous sequence; • The frequency of emptying sequences is defined according to the occupancy rate of the effluent production units lia, 11b, 11c, 1 Id connected to the installation; • after at least one or more emptying sequences, the main management unit 10 determines the order of emptying cycles during a subsequent emptying sequence based on the volumes of effluent collected at each of the collection points 7b 72, 73, 74 during one or more previous emptying sequences; • one or more collection terminals 7b 72, 73, 74 are excluded by programming from one or more subsequent drainage sequences in case of detection of failure of a motorized valve 8 and / or of the control electronics 9 corresponding to this or these collection terminals 7b 72, 73, 74; • an emptying sequence is interrupted in the event of an automatic and / or manual emergency stop command; • the pressure is measured continuously or discontinuously at least in the main pipeline 4; • a drainage sequence is interrupted if the pressure measured at a given time and / or over a given time range in the main pipe 4 is greater than a threshold value; • a manual emptying command issued from the manual control means of a collection terminal 7b 72, 73, 74 is recorded at the level of the main management unit 10 and a draining cycle of said collection terminal 7b 72, 73, 74 is ordered as a priority either immediately, or after interruption of a draining sequence, or immediately at the beginning of a draining sequence occurring during the next pre-programmed time period allowing the execution of draining cycles, or at the beginning of this pre-programmed time period allowing the execution of draining cycles; • The main management unit 10 transmits in the form of data to the remote processing unit 15 all or part of the information relating to the emptying sequences and / or emptying cycles. • The main management unit 10 is programmed from the remote processing unit 15.

[0065] Electrical junction boxes are typically already installed along quays or boat mooring pontoons. Often, such The cabinet is positioned between two locations allowing the connection of two boats. If the collection terminals 7b 72, 73, 74 can be individualized along these quays and pontoons, it is conceivable that, similarly to electrical connection cabinets, two collection terminals could be housed in the same enclosure for the connection of two boats in adjacent locations.

[0066] If this housing can be designed to accommodate the control electronics 9 of each of the motorized valves 8 of these two joint collection terminals, this control electronics 9 of these motorized valves 8 advantageously takes position in a dedicated housing in the electrical connection cabinet.
