Definitions

  • the present invention concerns the sector of equipment and components for the production of waste treatment plants. More specifically, it concerns a membrane gas holder dome with reduced heat loss, usable in particular for the storage of biogas generated by the digestion of sludge or slurry, or for the storage of gas emitted by liquid collection tanks.
  • Membrane gas holder domes are designed to be positioned on a tank, in technical jargon defined as digester, inside which a waste treatment process is carried out at controlled temperature and generally comprise a first inner membrane which delimits a gas storage chamber and a second outer membrane which defines a pressurization chamber, generally air-operated, positioned over said gas storage chamber.
  • the storage chamber communicates directly with the tank containing the waste, generally in the form of liquids or sludge, which emits the biogas.
  • the pressurization chamber is connected to an auxiliary air fan which maintains a certain pressure inside said chamber, in collaboration with calibrated discharge valves.
  • the pressure exerted by the pressurization chamber on the gas storage chamber allows delivery of the gas at the desired pressure, according to the use of the gas and the stabilization of the holder dome with respect to atmospheric agents.
  • the membranes are flexible, generally made of polyester fibre fabric covered on both sides by a layer of plastic material, normally PVC.
  • the membranes have a very reduced thickness which is ineffective against the transmission of heat by conduction.
  • Said membranes are therefore not able to limit heat losses, both by conduction and convection, and above all by radiation.
  • a membrane gas holder dome for positioning on a tank containing waste from which biogas is emitted.
  • Said holder dome comprises two superimposed membranes impermeable to the gases.
  • a first membrane delimits a storage chamber for the combustible gas;
  • a second membrane delimits a pressurization chamber superimposed on said storage chamber.
  • At least one of said membranes has a reflective surface, with heat insulating function, facing the tank containing the waste.
  • the object of the present invention is to eliminate the drawbacks and disadvantages previously described.
  • the main object of the present invention is to increase the energy efficiency of combustible biogas production plants, preventing heat losses through the gas holder domes, in order to reduce the energy consumption necessary to maintain the correct operating temperatures inside the digesters.
  • the object of the present invention is to provide a gas holder dome with reduced heat loss which is easy and inexpensive to produce and is easy to install and maintain.
  • a membrane gas holder dome with reduced heat loss adapted to be installed on a heated digester for the production of combustible gas, comprising:
  • said membrane in plastic material comprises a panel made of polyethylene, and said reflective metal foil is made of aluminium.
  • said reflective metal foil comprises an upper micro covering and a lower micro covering in polyethylene.
  • said lower micro covering is transparent.
  • said layer of composite material comprises a bubble polyethylene panel interposed between said membrane made of plastic material and said reflective metal foil, adapted to create an air gap between said layers.
  • said gas holder dome comprises one or more panels made at least partially with said composite material, arranged above said first membrane, in contact with it.
  • gaps are provided in said metal foil.
  • said panels are associated with one another by means of elastic joints or bindings.
  • said gas holder dome comprises a third membrane, impermeable to gases, made with said composite material with heat-insulating function and impermeably associated with said second membrane and adapted to delimit, in cooperation with the latter, said pressurization chamber.
  • said panels comprise projecting edges produced with said membrane made of plastic material and can be associated with one another in a manner impermeable to gases by means of heat sealing of said projecting edges, so as to produce said third membrane.
  • the main advantage obtained with the present invention consists in the considerable reduction in heat loss, in particular by radiation.
  • the metal foil of the layer of composite material intercepts the heat radiations emitted from said first membrane and reflects them, returning them to the gas storage chamber.
  • the heat loss by radiation of the gas holder dome are thus drastically reduced.
  • the bubble polyethylene panel creates an air gap between the metal foil and the upper polyethylene panel: said air gap reduces heat loss by conduction as it prevents direct contact between the metal foil, conductor of the heat, and the polyethylene panel.
  • the reduction in heat loss results in a reduction in energy costs for heating the digester.
  • the bubble polyethylene panel provides close but discontinuous supporting points between the metal foil and the upper polyethylene panel: in this way, a uniform constant distance is maintained between foil and panel. Due to the greatly reduced thicknesses, and consequent flexibility of the materials, the metal foil and the upper panel would tend to come into contact, adhering to each other, if not correctly spaced, annulling the thickness of the air gap.
  • the polyethylene upper covering of the reflective metal foil favours seal-coupling to the polyethylene panel impermeable to gases or to the bubble polyethylene intermediate panel.
  • the polyethylene lower covering of the reflective metal foil acts as a protection of the foil against the oxidization caused by gases emitted from the waste being digested.
  • said lower covering since it is transparent, does not absorb any heat radiation and guarantees full reflection of said radiation, with an efficiency of over 90%.
  • Said insulating composite layer advantageously protects said first membrane both from sources of UV light coming from the outside and from the danger of oxidization caused by the air pumped by the inflation means. This results advantageously in less wear and longer duration of said first membrane.
  • a plurality of panels made of composite material can be connected to one another to cover the entire surface of said first membrane.
  • each panel is produced with the membrane made of plastic material and therefore they are easy to seal together to provide a stable coupling.
  • a third membrane with said insulating composite layer constitutes a further barrier to the passage of gas from the storage chamber to the pressurization chamber. Any gas leaks from the storage chamber are confined within the space between the first membrane and the third membrane, from where they can flow to the outside, because the pressure in said space, directly in contact with the atmosphere, is considerably lower than both that of the gas and that of the air in the pressurization chamber.
  • a membrane gas holder dome 10 with reduced heat loss is illustrated, adapted to be installed on a heated digester adapted to produce combustible gas.
  • Said digester consists of a tank 12 made of concrete, having circular shape, provided with a base 12' and a lateral wall 12", adapted to contain sludge or slurry L.
  • Said membrane gas holder dome 10 essentially comprises:
  • Said gas holder dome 10 comprises inflation means for inflating said pressurization chamber C2 by means of an auxiliary gas, preferably air.
  • Said inflation means generally comprise a fan or air compressor 15 and pipes 16 connected to said second membrane. Further accessory elements belonging to the known art in the sector are relief and safety valves for the air 17 and for the gas 18.
  • Said first membrane 1 and said second membrane 2 are anchored to the top of the lateral wall 12" of the tank 12 of the digester by flanged mechanical anchoring means of known type.
  • a column 13 is provided adapted to support a mesh 14, anchored to the edge of said lateral wall 12", adapted to sustain said first membrane 1, preventing it from touching the free surface of the slurry L contained in the tank 12 during the intermediate phases of filling of the storage chamber C1.
  • detection means 19 for detecting the volume of the storage chamber C1 are positioned, adapted to allow measurement of the quantity of gas contained in said chamber.
  • Said first membrane 1 and said second membrane 2 are made of polyester fibre fabric 20 covered on both sides by a layer 21 of PVC.
  • said gas holder dome 10 comprises a layer of composite material with heat insulating function arranged over said first membrane 1, resting on it.
  • Said layer of composite material comprises:
  • Said layer of composite material is oriented so that said metal foil 6 is facing said first membrane 1.
  • said reflective metal foil 6 is extremely thin to guarantee the composite material maximum flexibility, and comprises an upper micro covering 7 and a lower micro covering 8 in polyethylene, in the order of 10-50 micron.
  • Said micro coverings are made of transparent polyethylene.
  • said layer of heat insulating composite material is made from one single panel 4 resting on said first membrane 1 (stratigraphy detail of Figure 3 ).
  • said layer of heat insulating composite material could be made of several panels 4, associated with one another by means of joints or elastic seals or by means of bindings.
  • said composite layer with heat insulating function creates a third membrane 3.
  • said third membrane 3, impermeable to gases, is impermeably associated with said second membrane 2 and is adapted to delimit, in cooperation with it, said pressurization chamber C2.
  • Said third membrane 3 is therefore interposed between said first membrane 1 and said second membrane 2.
  • Said third membrane 3 is advantageously produced so as to rest on said first membrane 1 in a gas permeable manner, to allow any gas leaks to flow out between the two membranes 1, 2 towards the edge, and then to the outside, from any point of the storage chamber.
  • the membrane made of plastic material 5 spills over from the layers below, to create projecting edges 4', i.e. a sort of selvage.
  • the projecting edges 4' of adjacent panels can be sealed to each other in a gas impermeable manner, since the membrane made of plastic material 5 is heat sealable. In this way, it is possible to cover increasingly large areas, until entirely covering said first membrane 1 with a further membrane impermeable to gases.
