Definitions
- the present invention relates to screening machines, in particular for screening waste comprising fibrous materials, and processes using such screens. More particularly, the present invention relates to machines for screening waste containing sticky and wet fibrous materials, such as organic materials, mixed with undesirable substances, in particular metals, minerals, plastics, glass, and treatment of said waste using such screens,
- Waste treatment processes for energy recovery and / or material recovery are in constant development.
- waste treatment processes for energy recovery and material recovery we can cite, in particular, anaerobic digestion processes, which aim to produce biogas and composting processes applied after methanation or directly to fresh household waste containing biogas. organic materials.
- the raw material of these processes can be waste from selective collections, green waste, kitchen waste or waste from the food industry, or even household waste from non-selective collections containing different categories of materials, such as putrescible waste. (food waste, green waste), paper, cardboard, glass, plastic, ferrous or non-ferrous metals, fabrics, sanitary textiles, and possibly household hazardous waste (DDQD) (electric batteries, ).
- DQD household hazardous waste
- anaerobic digestion and / or composting of household waste with a view to transforming it into biogas and / or recoverable compost involve three to four main stages:
- mechanical waste preparation which aims to separate biodegradable organic matter from other non-biodegradable fractions or compost; this step may include various grinding and / or screening, as well as the passage of the waste in a rotary tube of pre-fermentation, generally essentially horizontal, which constitutes a medium for such preparation.
- the treatment of unsorted household waste requires one or more screenings and ballistic separation operations, which will make it possible to sort the materials according to their particle size and density, and to separate the biodegradable organic materials from the other non-biodegradable fractions or in compost, whether it is light fractions (plastic films, hard plastic, ...), or heavy fractions (glass, pebbles, metals ).
- CSR solid fuels recovery
- All these processes implement one or more sorting operations, and / or grinding and / or screening.
- a fine screening using a fine sieve mesh allows, in the mechanical preparation phase preceding the actual methanation, to optimize the collection of organic materials that can be valorized in methanisation and compost, and which concentrate in the fine fraction in particular after passing through a rotating pre-fermentation tube.
- this fine screening must make it possible to recover a fraction of waste less than 5 millimeters in size, in which the organic matter is concentrated, which can be used for biogas and compost.
- the fine screening thus makes it possible to select the materials to be treated according to their granulometry and to separate degradable organic materials and mineral materials.
- a fine or very fine screening is useful for the calibration of RDF (Refuse Derived Fuels) and CSR (Solid Recoverable Fuels), obtained from the grinding of the light coarse fraction from household waste and / or dry waste with a high calorific value, especially plastics, wood, composite wood, refusal of automobile grinding, textiles from which we seek to eliminate fines.
- RDF Refuse Derived Fuels
- CSR Solid Recoverable Fuels
- the existing devices use relatively large mesh sizes that prevent the loss of organic matter but do not offer the selectivity necessary for the purification of the latter, or they also offer self-cleaning screens or integrating periodic cleaning.
- Patent EP 1 957 210 thus discloses a "flip-flop" screening machine, also called a trampoline screen, or a voltage wave screening machine. It is an equipment whose sieving surface, inclined (at about 20 ° relative to the horizontal), consists of a flexible fabric made of synthetic material with closed meshes. This canvas is successively stretched and released by motorized sleepers to which it is attached. These high frequency movements generate an acceleration of several tens of "g" objects on the screening screen and take off so as to cause unclogging. However, it is necessary to periodically wash these fabrics with water under high pressure which causes problems of immobilization and management of cleaning water, as well as the risk of embrittlement or perforation of the fabric.
- EP2 364 782 discloses the use of a trampoline screen for screening wet organic materials with webs having a mesh size of 10 millimeters. This application also mentions risks of chemical attack of these fabrics, when relatively wet organic waste is screened.
- the meshes of these screens may consist of slots, square, rectangular or round openings. Their dimensions generally vary for wet household waste between 8 and 12 millimeters. With these devices, it seems difficult to screen, waste comprising wet organic materials with a mesh size of less than 10 mm without clogging the fabrics. In any case, the opening of the mesh grows and decreases with the movements of the canvas, which can cause quality problems.
