Definitions

• the invention relates to an energy-saving combination. It is for the good of the environment to make very sparing use of energy and to limit the emission of harmful substances . It is particularly important to limit the emission of carbon dioxide gas and thus prevent further intensification of the greenhouse effect on earth.
• Known measures for saving energy and reducing CO 2 emission are for instance the reduction in processes that are very wasteful of energy and the reuse of already produced material .
• the use of means of transport which emit less carbon dioxide is also being stimulated as alternative to means of transport which do have a high CO 2 emission. In the case of houses the use of durable materials and insulation of houses is stimulated.
• the use of energy-saving appliances is one of a series of measures aimed at decreasing CO 2 emission and reducing the consumption of energy.
• US-A-5 527 464 describes a combination wherein waste from a community is taken to a waste fermentor.
• the carbon dioxide and the water from the waste fermentor are supplied to, among others, an open horticulture greenhouse.
• the gas from the fermentor can be used to generate energy. It is now an object of the invention to provide an energy-saving combination which contributes " " toward the above stated objectives.
• a combination according to the invention comprising: - at least one house with an outgoing fermentable waste flow and an outgoing waste water flow, - at least one anaerobic waste fermentor with an ingoing waste flow and an outgoing fermentor gas flow; and - at least one closed horticulture greenhouse, wherein the fermentable waste flow runs out into the anaerobic waste fermentor, the waste water flow and at least the carbon dioxide part of the fermentor gas flow runs out into the closed greenhouse, wherein condensed water and/or a heat flow from the closed greenhouse is supplied to the at least one house.
• the fermentable waste flow from a house is usually removed via the domestic refuse to a central tip or incineration furnace.
• vegetables, fruit and garden waste are separated from the other domestic waste and processed separately at a central location.
• Water from shower and bath, water from the kitchen and water from the toilets is. normally carried via one sewage system to a central water treatment plant.
• a house is understood to mean any building in which people and/or animals reside on regular basis, such as care centres, offices, shops, livestock accommodation etc. With the combination according to the invention these different waste flows are reused for the benefit of the at least one house.
• the fermentable waste flow such as for instance vegetables, fruit and garden waste and the water from the toilets is fed to a waste fermentor, which produces an increased CO 2 content which is then " in turn converted by the greenhouse, and in particular the crops cultivated therein.
• a preferred embodiment of the combination according to the invention comprises a gas turbine, gas motor or a high temperature fuel cell, which is placed in the fermentor gas flow and converts at least the combustible part of the fermentor gas flow into water vapour and carbon dioxide.
• the anaerobic waste fermentor also produces combustible gases, in particular methane.
• the combination according to the invention thus ensures that electric current is generated from the waste flow produced by the at least one house, which current can be reused by the at least one house.
• a high temperature fuel cell such as a melted carbonate, or solid oxide fuel cell, has the additional advantage of a higher efficiency and cleaner gas emissions .
• the heat generated by the gas turbine or gas motor is supplied to the greenhouse and/or the fermentor and/or the at least one house.
• Another preferred embodiment of the combination according to the invention comprises a water-bearing soil layer or basin, wherein a heat flow from the greenhouse is supplied to the water-bearing soil layer. During the summer or during the day excess heat from the greenhouse can be supplied to the water-bearing soil layer, while in the winter or at night heat from this water-bearing soil layer or basin can be fed back for the purpose of heating the greenhouse and/or a house.
• heat is exchanged between the water-bearing layer and the at least one house.
• the 1 water-bearing layer which is comparatively cool in the summer, can thus also be used for instance to lower the temperature in the at least one house.
• cooling means such as for instance a cooling tower, for the purpose of cooling the water-bearing layer.
• a photovoltaic layer is arranged at least partially on the at least one house for generating electricity from light. The thus generated electricity can be used during daylight to drive the different installations and to provide the houses with electricity. In addition, the electricity can optionally be stored for use during the night.
• This combination preferably further comprises a device for generating hydrogen using the photovoltaic electricity.
• This hydrogen can be readily formed from for instance the condensed water. This hydrogen can in turn then be used to provide energy. The hydrogen can for instance be used to propel a vehicle. It is further also recommended here to supply the hydrogen to the fermentor in order to convert the hydrogen ⁇ into methane.
• the bacteria used will easily convert the hydrogen, in combination with CO 2 , into methane.
• the advantage of methane is that it is more readily compressible and can thus be used more easily for vehicles or for storage in order to generate electricity again during the night.
• This fermentor 3 is an anaerobic fermentor which emits a fermentor gas flow 4 as a result of the anaerobic fermenting process .
• This fermentor gas 4 contains, among others, CO 2 and methane gas.
• the fermentor gas is fed to a turbine 5 or a gas motor which here converts the combustible part of the gas flow into electricity 6, heat 7 and CO 2 .
• the heat flow 7 is fed back again to fermentor 3 to thus hold this latter at the correct operating temperature.
• the gas 8 burned by turbine 5 or the gas motor which now consists mainly of CO 2 and water, is fed to a cooler 9.
• the water in gas flow 8 is here condensed, and is then fed via flow 10 to a greenhouse 11.
• Waste water 12 from house 1 is used to irrigate the crop.
• This waste water 12 consists substantially of bath and shower water.
• the crop grows under the influence of sunlight 13 incident upon the greenhouse 11.
• Excess heat 14 can be supplied from greenhouse 11 to a water-bearing soil layer 15 which can function as buffer for heat.
• the heat stored in this water layer can subsequently be supplied vie a heat flow 16 to greenhouse 11, in the case the outside temperature is low, and fed back again via a heat flow 17 to houses 1.
• Condensed water from greenhouse 11 can further be supplied via flow 18 to the at least one house 1.
