Definitions

  • the invention 2 presented in this PCT request consists of a system that allows a cost effective and energy efficient way to reuse bath grey water in toilet flushing, avoiding or reducing the consumption of clean water that would otherwise be required for that end.
  • the cost effectiveness is achieved by a simple design that allows simultaneously a low initial cost and a low running cost of the system.
  • the core of the invention is a "Micro Hydraulic Turbine-Pump” (MHTP) component, which basically consists of a small hydraulic turbine coupled to a small hydraulic continuous rotating pump through a common rotating shaft, being these rotors located in separate casings.
  • MHTP Micro Hydraulic Turbine-Pump
  • the MHTP is somehow comparable to a turbo-compressor used in car engines, but in this case the working fluid in the turbine side is clean water supplied by the water utility, while the working fluid in the pump side (analogous to the compressor in car engines) is grey water recovered from the bath taken by an individual user.
  • the purpose of the MHTP is to extract part of the energy contained in the water being supplied by the water utility system 3 (at a given minimum pressure and flow) and use that energy to pump part of the bath grey water to a "Grey Water Storage Tank” (GWST), which is located at a higher gravitational energy level.
  • GWST Greeny Water Storage Tank
  • the water supplied by the water utility system is firstly routed to the turbine side of the MHTP, transferring energy to the turbine. After leaving the turbine, although with less energy content than before, the utility water flows to the shower and is consumed by the user in a shower bath.
  • the resulting grey water After being used in the bath, the resulting grey water would normally flow to a draining pipe through the action of gravitational force and would then follow directly to the sewer system. In this case, however, the grey water resulting from the bath is collected in a "Small Regulation Tank” (SRT), which is located at a lower level than the bath tub.
  • SRT Standard Regulation Tank
  • the SRT is connected to the pump side of the MHTP so that the accumulated grey water is pumped from the SRT to the GWST at the same time that clean water from the utility system is being consumed.
  • the pump is driven by the turbine side of the MHTP, since these two rotors (turbine and pump) of the MHTP are coupled through a common rotating shaft.
  • the purpose of the SRT is to allow the accumulation of a minimum amount of grey water in order to facilitate the pumping process.
  • the SRT is also connected to the draining pipe, in a way that allows any excess grey water to flow normally to the sewer.
  • the recovered grey water coming from the SRT Before entering the pump side casing of the MHTP, the recovered grey water coming from the SRT first passes through a "Grey Water Filter” (GWF) and is filtered in order to avoid the accumulation of dirt in the pump side of the MHTP, which could otherwise affect its mid-term operating efficiency
  • GWF Grey Water Filter
  • water utility system used throughout this document refers to the water supply infrastructure of the local water supplier company (water distribution company), which supplies clean (and eventually potable) water to the individual consumer and is located upstream of the water consumption and of the invention application. and durability.
  • the GWF is designed to allow easy cleaning by the end-user without using any tools.
  • the MHTP also integrates a "By-Pass Valve” (BPV), so that the user may regulate the fraction of utility water flow going into the turbine side of the MHTP or bypassing it.
  • BBV Binary-Pass Valve
  • the regulation of the amount of utility water flowing into the turbine side of (or bypassing) the MHTP allows the user to adjust the amount of pumped bath grey water and the water pressure available in the shower. In other words, increasing the amount of utility water passing through the MTHP turbine will have as a consequence a larger amount of grey water being pumped to the GWST and, at the same time, a lower water pressure available in the shower.
  • the BPV thus allows the establishment of a compromise between the amount of grey water recovered and the comfort of use of the shower. It also allows the user to easily stop using the system at any time, by simply bypassing all the water being supplied by the water utility system.
  • the GWST will stock the recovered grey water until it is needed to fill in the toilet flush tank. It is designed in a way that allows any excessively recovered grey water to flow normally to the sewer and is equipped with a "Discharge Valve” (DV) that allows the user to completely empty the GWST whenever that may become necessary (e.g. for periodic cleaning or dismantling).
  • DV discharge Valve
  • the grey water stored in the GWST flows by action of gravity to a "Water Source Selection Valve” (WSSV), which has the purpose of selecting the water source to be used to refill the existing toilet flush tank.
  • WSSV Water Source Selection Valve
  • the WSSV guarantees that priority is always given to the grey water coming from the GWST whenever it is available.
  • the WSSV allows clean utility water to refill the toilet flush tank. This way the refill of the toilet flush tank is guaranteed in all situations.
  • the WSSV may be designed as a water float valve type, similar to those used in toilet flush tanks.
  • the float valve When a determined minimum level of grey water is available in the WSSV tank, the float valve obstructs the flow of the utility water.
  • the grey water level in the WSSV tank falls below the determined minimum level (meaning there is no grey water available to refill the toilet flush tank), the water float valve opens and allows the flow of the utility water to the toilet flush tank.
  • the system may require the use of a non-return valve in order to assure that the pipe between the SRT and the MHTP is always filled with grey water.
  • this non-return valve may be avoided if the design of the pump allows it to operate in dry mode.

Abstract

L'invention porte sur un système qui utilise exclusivement la gravitation et l'énergie contenue dans l'eau délivrée par le système public de l'eau, comme sources d'énergie, pour recueillir, stocker et réutiliser des eaux grises de bains dans des applications domestiques individuelles. L'invention est caractérisée par la combinaison d'une turbine hydraulique de petite taille (2) et d'une pompe rotative hydraulique de petite taille (6), toutes deux couplées par l'intermédiaire d'un arbre rotatif commun (4), formant un dispositif unique utilisé pour extraire de l'énergie à partir de l'eau qui est délivrée par le système public de l'eau et pour utiliser simultanément cette énergie pour pomper des eaux grises de bains récupérées à un niveau plus élevé d'énergie potentielle de gravitation. Un réservoir d'accumulation d'eaux grises (3) situé à un niveau d'énergie potentielle de gravitation plus bas et un réservoir de stockage d'eaux grises (5) situé à un niveau d'énergie potentielle de gravitation plus élevé complètent le cœur du système.
