Korte aanduiding: Werkwijze voor het aëroob composteren van organisch afval.Short designation: Method for aerobically composting organic waste.
De uitvinding heeft betrekking op een werkwijze voor het aëroob composteren van organisch afval door middel van het blazen van lucht door dit afval, dat zich bevindt in een opslaghal.The invention relates to a method for aerobically composting organic waste by blowing air through this waste, which is located in a storage hall.
Deze werkwijze is bekend. Op een terrein of op of in de bodem van een 5 opslaghal zijn roosters boven goten of geperforeerde buizen gemonteerd, die zijn aangesloten op ëên of meer afzuig- of blaasventilatoren. Op deze roosters of buizen wordt het afval gestort, dat kan bestaan uit huisvuil, huishoud- of industrieslib, mest, plantaardig afval enz. Door het doorblazen van de lucht wordt het afval verbrand respectievelijk gecomposteerd.This method is known. On a site or on or in the bottom of a storage hall, gratings are mounted above gutters or perforated pipes, which are connected to one or more exhaust or blow fans. The waste is deposited on these grids or pipes, which may consist of household waste, household or industrial sludge, manure, vegetable waste, etc. By blowing through the air, the waste is burned or composted.
10 Gevormde dampen, bijvoorbeeld ammoniakhoudend, worden via een filter in de buitenlucht geblazen, waardoor stankoverlast wordt voorkomen.10 Formed vapors, for example containing ammonia, are blown into the air through a filter, preventing odor nuisance.
De uitvinding beoogt nu om voor de opslaghal, die bij voorkeur wordt gebruikt, o.a. om stankoverlast van de omgeving en beïnvloeding door regenen sneeuwval te voorkomen, een op zichzelf bekende, goedkope constructie 15 toe te passen en tevens de compostering te bevorderen.The object of the invention now is to use a per se known, inexpensive construction 15 and to promote composting for the storage hall, which is preferably used, inter alia to prevent odor nuisance from the environment and influence by rain from snowfall.
Dit wordt volgens de uitvinding bereikt doordat de opslaghal wordt gevormd door een gesloten kunststoftent, waarbinnen een luchtoverdruk wordt onderhouden, die het doorblazen van de lucht bevordert.This is achieved according to the invention in that the storage hall is formed by a closed plastic tent, within which an air overpressure is maintained, which promotes the blowing of the air.
Een blaashal is goedkoop t.o.v. andere gebouwen en heeft als verder 20 voordeel dat de kunststof niet door de uit de afval opstijgende zure of basische dampen wordt aangetast. Verder wordt dee toch reeds in de hal aanwezige overdruk, die de hal overeind houdt gebruikt om de lucht rechtstreeks door het afval te voeren, zodat daarvoor geen extra ventilatoren aanwezig behoeven te zijn. Een voordeel is daarbij dat de blaashal, in tegen-25 stelling tot andere gebouwen, een luchtdichte constructie is, zodat geen lucht weglekt. De druklucht is ook gelijkmatig rond de afvalhopen verdeeld aanwezig, doordat de gehele hal zich onder overdruk bevindt.A blower hall is cheap compared to other buildings and has the further advantage that the plastic is not affected by the acidic or basic vapors rising from the waste. Furthermore, the overpressure already present in the hall, which keeps the hall upright, is used to pass the air directly through the waste, so that no additional fans need to be present for this. An advantage here is that the blowing hall, in contrast to other buildings, is an airtight construction, so that no air leaks out. The compressed air is also distributed evenly around the waste heaps, because the entire hall is under overpressure.
Bij voorkeur wordt warmteuitwisseling tussen de uitgeblazen lucht en de voor het onderhouden van de overdruk toegevoerde en voor het composteren 30 gebruikte lucht toegepast.Preferably, heat exchange between the blown out air and the air supplied for maintaining the overpressure and used for composting is used.
Hierdoor wordt de door afvalverbranding gevormde warmte opnieuw gebruikt om de, met name fs winters, koude buitenlucht voor te warmen, en het vocht daarin te condenseren, hetgeen de verbranding c.q. de compostering bevordert.As a result, the heat generated by waste incineration is reused to preheat the cold outside air, in particular during winters, and to condense the moisture therein, which promotes combustion or composting.
35 De afgezogen lucht wordt, zoals bekend, via filters in de buitenlucht afgevoerd.As is known, the extracted air is exhausted through filters in the open air.
Het is mogelijk als draagrooster voor het afval een transportinstalla-tie te gebruiken, die het afval al of niet continu via een sluis in de 8701118 1 -2- blaashal brengt, waarbij delen van de transportinstallatie van de noodzakelijke perforaties voor de luchtdoorblazing zijn voorzien.It is possible to use a transport installation as a support grid for the waste, which may or may not bring the waste continuously via a sluice into the 8701118 1-2 blow hall, whereby parts of the transport installation are provided with the necessary perforations for the air blowing.
Het afval kan ook in ruggen worden gestort rond een of meer geperforeerde buizen.The waste can also be deposited in ridges around one or more perforated pipes.
5 Een andere mogelijkheid bestaat uit kanalen of verdiepingen, gevormd in de bodem van de hal, waarboven geperforeerde roosters zijn gemonteerd.Another possibility consists of channels or floors, formed in the bottom of the hall, above which perforated grids are mounted.
Eventueel kan de werking ten gevolge van de overdruk worden gecombineerd met afzuiging aan het uitlaateinde van de kanalen of buizen.Optionally, the effect due to the overpressure can be combined with extraction at the outlet end of the channels or pipes.
