Definitions

  • the invention relates to sewage heat recovery facilities, particularly heat recovery units for heating municipal buildings or industrial objects and providing hot water to multi -apartment houses.
  • the UK patent application publication No. 2 304 977 describes a water supply system with heat recovery where warm sewage is delivered to a heat exchanger before being drained to the sewer system, thus partially recovering contained heat and supplying the heat back to the system.
  • the aim of this invention is to improve the effectiveness of a heat recovery facility and increase the efficiency ratio of heat recovery while improving maintenance.
  • the purpose of the invention is achieved by creating a heat recovery unit that contains the following main elements: a warm sewage settling tank, a solid sewage settling tank, a warm wastewater supply pipe, a sewage discharge pipe, a pressure sewage discharge pipe, a sewage pump, a sewage flush valve, a heat exchange circuit, and a heat pump.
  • the warm sewage enters the warm sewage settling tank via the solid particle settling tank's overflow channel or T-junction into the solid warm sewage settling tank, from which it is subsequently removed to the sewer from the lower part of the settling tank, via a discharge pipe connected to the warm sewage settling tank.
  • the overflow channel or T-junction of the solid particle settling tank is the only element through which warm sewage can enter the warm wastewater settling tank from the solid particle settling tank.
  • the sewage heat recovery unit contains a heat exchange circuit inside the sewage settling tank (around the solid particle settling tank) in order to recover heat from the sewage inside the warm sewage settling tank.
  • the heat exchange circuit is connected to a heat pump for recovery of sewage heat.
  • the heat exchange circuit is arranged closer to the outer surface of the solid sewage settling tank than to the inner surface of the warm wastewater settling tank to increase the heat recovery efficiency also from the wastewater flowing into the solid sewage settling tank.
  • the heat exchange circuit is placed directly next to the outer surface of the solid particle settling tank, further improving heat recovery efficiency.
  • the heat exchange circuit is placed around the outer wall of the solid particle settling tank, preferably in a helical configuration.
  • the unit contains pressure sewage discharge pipe 5, connecting solid particle settling tank 2 to sewage supply pipe 4.
  • One end of pressure sewage discharge pipe 5, which is inside solid particle settling tank 2, is connected to sewage pump 6.
  • Sewage pump 6 is placed in the lower part of the solid particle settling tank 2 - at the very base of solid particle settling tank 2. Sewage pump 6 is also connected to pressure sewage discharge pipe 5 so that the wastewater pumped out by the sewage pump 6 can be sent to the aforementioned sewage supply pipe 4.
  • Heat exchange circuit 9 is closer to the external surface of solid particle settling tank 2 than to the internal surface of warm sewage settling tank 1, increasing the effectiveness of recovering heat from wastewater that flows into solid particle settling tank 2.
  • Helical heat exchange circuit 9 is situated near the external surface of solid particle settling tank 2.

Abstract

L'invention concerne des installations de récupération de chaleur à partir d'eaux usées, en particulier des unités de récupération de chaleur servant à chauffer des bâtiments municipaux ou des objets industriels et à fournir de l'eau chaude à des maisons comprenant plusieurs appartements. L'unité de récupération de chaleur à partir d'eaux usées comprend un réservoir de sédimentation d'eaux usées chaudes (1) ; un réservoir de sédimentation d'eaux usées solides (2) placé à l'intérieur du réservoir de sédimentation des eaux usées chaudes (1) ; un tuyau d'alimentation (3) en eaux usées chaudes à travers lequel les eaux usées chaudes sont introduites. L'unité de récupération de chaleur à partir d'eaux usées comprend une pompe (6) d'eaux usées placée à l'intérieur du réservoir de sédimentation d'eaux usées solides (2) et une soupape de chasse (8) d'eaux usées destinée à broyer une couche développée de particules solides dans le réservoir de sédimentation d'eaux usées solides (2). L'unité comprend un circuit (9) d'échange de chaleur doté d'une pompe à chaleur (10) destinée à retirer la chaleur présente dans les eaux usées contenues dans le réservoir de sédimentation d'eaux usées chaudes (1).
