Definitions

  • This invention refers to a lid jointed to a waste container for material with odour-producing exhalation as well as to a process for eliminating odours from such a waste container.
  • a small opening such as a slot, protected by liner, may be provided for in the lid this serves only to reduce the rush of offensive gaseous materials from the soiled diapers stored in the container (shell) caused by the draft pulled by rapid opening of the lid by the access of air from outside thus creating a counter-pressure (column 9, lines 48 to 59).
  • EP-A-0 597 282 there has been described a collecting container for organic wastes from household, small businesses or the like to be led to composting or fermenting in which a ventilation aperture has been disposed in the lid of the collecting container and it has been provided for a bio filter disposed interchangeably within the collecting container in front of the ventilation aperture.
  • a ventilation aperture has been disposed in the lid of the collecting container and it has been provided for a bio filter disposed interchangeably within the collecting container in front of the ventilation aperture.
  • a special embodiment there are disposed on the lid several somewhat sloping ventilation apertures on the top and additionally lateral apertures.
  • the problem underlying to the invention is to create a lid for a waste container by which the odour-producing exhalation is eliminated from the gases and vapours emanated by the waste and also the non-adsorbed gases and vapours are rapidly eliminated in a simple way to a largest extent as well as a corresponding process for eliminating odour-producing exhalation from waste containers.
  • a subject matter of the invention is a lid jointed to a waste container for material with odour-producing exhalation, the lid being fitted internally with means for eliminating the said exhalation in a removable interchangeable way, said means being disposed distant from the undersurface of the upper part of the lid, the lid having laterally disposed ventilation holes in a number and of sizes sufficient to let out the non-adsorbed gases and vapours passed through the means for eliminating the said exhalation to the outside, characterised in that the means for eliminating the said exhalation is a filtering panel consisting of or comprising an adsorbent for the odour-producing exhalation and that the ventilation holes lead into a space at the front of the lid between an extended portion of the upper part of the lid and a horizontal or almost horizontal portion of the lateral border of the lid parallel or almost parallel to the upper part of the lid.
  • the non-adsorbed gases and vapours are such not or essentially not producing odour.
  • the present invention mainly differs in that by the arrangement of the filtering panel distant from the undersurface of the upper part of the lid and the lateral arrangement of the ventilation holes an intensive chimney effect is created by which the gases and vapours liberated from the odour-producing substances are rapidly drawn out of the container by the draught through the chimney-type arrangement of the ventilation holes.
  • the present invention mainly differs in that the lid of it has a sufficiently large space for creating a very intense chimney-like draught of the non--adsorbed gases and vapours through the holes. Moreover the lid is strictly prevented from receiving rain from outside because of that it has no holes on the top.
  • the filter material is of another type and its working is more simple and reliable. Hence contrary to the filter material of the said publication it is absolutely necessary to strictly exclude the entering of water as it has been realised according to the invention.
  • the filtering panel is disposed parallel or a little inclined in relation to the undersurface of the upper part of the lid. This for the reason that the gases and vapours come from below.
  • the filtering panel occupies an entire or nearly entire section inside the lateral border of the lid. This has the advantage of making sure that all odour-producing exhalation comes to the filtering panel and is adsorbed.
  • the filtering panel is inserted between two nets by having been fixed to the border joints of the nets the latter being fixed to lateral border portions of the lid.
  • the filtering panel is fixed to border portions of the lid.
  • the adsorbent material is activated carbon.
  • this is such prepared from carbonized material of vegetable origin by a heat treatment giving to them a great porosity.
  • carbonized material are coconut shells, wood of any type, peat, fossile coal, viscose rayon, polyacryl nitrile fibres, polystyrene and caoutchouc.
  • ion exchangers and silica gel are examples of further adsorbent materials.
  • the thickness of the filter panel is from 3 to 8 mm, particularly from 5 to 8 mm, for example 5 mm. Such great thicknesses are advisable for the case that the filter panel remains for longer periods, such as one year, in the lid. The greater the thickness of the filter panel the greater the adsorbing capacity.
  • the adsorbing capacity of the adsorbent is >4,5 mg/cm 2 , calculated on fluorobenzene of a concentration of 10%, or >3 mg/cm 2 , calculated on fluorobenzene of a concentration of 100%.
  • a subject matter of the invention is also a process for eliminating odours from waste containers by using a lid according to the invention.
  • the ventilation openings 5 ensure constant elimination of the gases and vapours produced in the container: in fact, immediately after having been produced, all the gases and vapours flow in a fine fluid layer in contact with the filter, the odour-producing exhalations are completely or almost completely adsorbed by the latter and the rest of gases and vapours immediately discharged to outside, completely or almost completely cleaned of their odour-producing fraction.
  • there is at most an extremely low concentration of odour-producing gases in the empty space inside the container both in the transitory phase after a quantity of waste is introduced and in the stationary phase, i.e. during the potentially long time lapse between one introduction of waste and another.
  • the filter 2 consists of a panel made of an adsorbent material that is capable of adsorbing every odour-producing exhalation deriving from the putrefaction of biomasses. This filter 2, fitted inside the ventilated lid, eliminates the odour-producing gases and vapours that have accumulated while the container was shut.
