Definitions

  • Destruction plants of this type are few, and may be located at very large distances from the individual slaughterhouses; which implies that the transports of the hazardous waste may become long.
  • offal has a certain intrinsic value, inasmuch as the same has a energy content, the same is thus a marked drawback for slaughterhouses and cutting-up plants, in particular from an economic point of view.
  • the slaughterhouses are in this manner hit by particular fees to the selected destruction plants, which take care of the waste.
  • a problem associated with offals is also that the bacterial growth in the same takes place quickly; something which implies that the transport to the destruction plant must be effected without delay. In other words, the waste cannot be stored for a long time.
  • the transports of the waste which is often effected on the highways, mean that traffic accidents may occur and give rise to infectious waste being liberated in the nature, with ensuing effects on the environment.
  • the present invention aims at managing the above-mentioned inconveniences connected with the handling of offal. More precisely, the invention is based on the idea of converting the offal to a useful fuel already in, or in connection with, the slaughterhouses or cutting-up plants. Therefore, a primary object of the invention is to produce a fuel in close connection to the cutting-up of animals, which is easy to handle and transport and which may be stored for a considerable time without giving rise to spread of contagion or smell.
  • An additional object is to provide a fuel which may be packed in a rational way in the immediate connection with the manufacturing process and which, after transport to a combustion plant, may be fed into the combustion plant in a simple way. It is also an object to provide a fuel, which has a good heating value.
  • At least the primary object is attained by the fuel defined in the characterizing clause of claim 1.
  • Preferred embodiments of the fuel according to the invention are furthermore defined in the dependent claims 2-4 .
  • the invention also relates to a method for the production of the same.
  • the features of said method are seen in the independent claim 5.
  • Pre- ferred embodiments of the production method are furthermore defined in the dependent claims 6-8.
  • numeral 1 designates a store for offals and 2 designates a cutting up device or disintegrator in which the waste from the store 1 may be cut up into smaller component parts.
  • the store 1 may either have a large volume for storing considerable quantities of waste, or have the character of an intermediate store of a limited volume. In both cases, it should be possible to feed out the waste batchwise to the dis- integrator 2, which in turn may consist of a conventional, commercially available mill for grinding purposes.
  • Numeral 3 designates a second store for receipt of a fibre material, which in practice may consist of wood shavings, wood chips, peat, bark, waste paper or a mixture hereof.
  • the store 3 is intended for such fibre material which is externally acquired and which already at the arrival to the shown plant exists in a finely divided form.
  • a third store is shown, in which also larger parts of fibrous material may be received, such as stumps of tree, tree branches, demolition wood, paper packages etc. From the store 4, said material may be emptied into a second disintegrator 5, e.g. a mill, in which the material may be divided into component parts of a suitable size.
  • a tank for liquid disinfectant is shown.
  • the disintegrators 2, 5, the store 3 and the tank 6 are in a suitable way connected with a central mixing device 7, in which the different fuel-forming components may be received batchwise.
  • the mixing device may advantageously consist of a tiltable tumbler of a commercially available type.
  • a conveyor 8 is schematically shown, on which a number of transport containers 9 for receiving and storing the ready-produced fuel are shown. The production of the fuel according to the invention is carried out in the following way.
  • the animal waste or offal which is used as one of two main raw material components may comprise miscellaneous carcass parts, e.g. skulls, bone pieces, spinal marrow parts, viscera, pieces of fat, blood, etc.
  • carcass parts e.g. skulls, bone pieces, spinal marrow parts, viscera, pieces of fat, blood, etc.
  • said carcass parts are milled or disintegrated to smaller component parts of a suitable size. More precisely, the disintegration should be driven so far that the component parts of the waste get a maximum size of 50 mm (bone and skull parts do in principle get the form of granules or solid bodies, while tissue parts get the form of rags of a limited length) .
  • the same When the disintegrated offal is fed out from the disintegrator, the same usually has a comparatively high moist or liquid content, the consistence of at least the tissue parts resembling the consistence of ordinary minced meat.
  • the requisite fibre material which basically is of a biological origin, is fetched from at least one of the two stores 3, 4.
  • said material may advantageously be chosen from the group: wood shavings, wood chips, peat, bark, or waste paper.
  • the material may also con- sist of a mixture of said starting materials. If the material is of a suitable granule size already in connection with delivery to the plant according to the invention, the same may be stored in the store 3. However, if the material comprises too large components, the same may be stored in the store 4 and then be disintegrated in the disintegrator 5.
  • a disinfectant in the form of tall oil is fetched.
  • tall oil constitutes a by-product from the production of sulphate pulp and is obtained from the resin substances of the trees.
  • the crude tall oil constitutes an mixture of principally 20-50 % resin acids and 35-55 % free fatty acids, such as oleic acid, linoleic acid and higher fatty acids.
  • Characteristic of tall oil, in addition to constituting a comparatively inexpensive by-product, is that the same has a disinfecting effect inhibiting the bacterial growth.
  • the disintegrated offal is fed batchwise into the mixing device 7 together with a suitable batch of tall oil from the tank 6 as well as a suitable batch of fibre material from either solely the store 3, solely the disintegrator 5, or from both of the same.
  • a suitable batch of tall oil from the tank 6 as well as a suitable batch of fibre material from either solely the store 3, solely the disintegrator 5, or from both of the same.
  • 50 parts by weight of offal, 49 parts by weight of fibre material and 1 part by weight of tall oil are charged into the mixing device 7.
  • the mixing member 7' of the device is brought in motion in order to mix and homogenize the different components.
  • the retention time of the material in the mixing device should amount to at least 5 minutes and preferably 10-20 minutes in order to guarantee an optimum homogenization of the material.
  • the same should be comparatively dry (the moisture content should not exceed 20 %) .
  • the wet offal is mixed with the comparatively dry fibre material components, the last-mentioned ones absorb and binds liquid, the tumbling of the components in the mixing device resulting in the formation of pellet-like or briquet-like bodies of a solid character.
  • said individual bodies are well separable and may be handled as other debris goods.
  • the formed fuel bodies may in regards of transport and storing be handled in the same way as pellets or briquets.
  • the fuel bodies may be emptied into a sealable container 9 which is brought out of the plant, e.g. via a conveyor 8.
  • the packed fuel may be stored and transported with a relatively high degree of freedom by the disinfectant tall oil effectively counteracting bacterial growth.
  • the fuel may be stored for weeks without having to be burnt.
  • Essential advantages of the invention is on one hand that offal which is difficult to handle is converted into a fuel of solid shape, and on the other hand that the fuel is disinfected, whereby the same may be stored for a considerable time without an aggravating bacterial growth. Therefore, the produced fuel may be handled, stored and transported in a rational and economically favourable way.
  • Another substantial advantage is that the produced fuel may be burnt in conventional destruction plants, e.g. thermal power stations (i.e. not necessarily in particular destruction plants) , possibly together with other fuels. Because of the comparatively high thermal value of not solely the fibre material components, but also the proper offal, considerable amounts of energy may be extracted and utilized.
  • the proportions between the components used in the initial mixture may deviate from the above-mentioned example. Principally, it should be emphasized that the share of wet offal may be increased, the dryer the fibre material component is. However, the content of offal in the material mixture should be within the range of 40-70 % by weight, suitably 45-55 % by weight. The share of disinfectant in the form of tall oil should be within the range of 0,5-2 % by weight. Experiments made have, however, shown that approx. 1 % by weight of tall oil is optimum in the balancing between raw material cost and bactericidal effect. Furthermore, it should be pointed out that also other components than those that are defined in the subsequent claim may be added to the initial mixture.

Abstract

L'invention concerne un combustible solide et son procédé de production. Ce procédé consiste à désintégrer les déchets d'abattage en petits constituants (dans un désintégrateur 2) et à les céder par lots à un dispositif mélangeur (7). Ce dispositif mélangeur est également alimenté par lots, d'une part, en matière fibreuse pulvérisée d'une certaine teneur en matière sèche (par un contenant 3 ou un deuxième désintégrateur 5) et, d'autre part, en agent désinfectant, dans une fraction moindre et sous forme de tall-oil (d'un réservoir 6). Ces composants sont mélangés et homogénéisés pendant un certain temps de séjour dans le dispositif mélangeur, le liquide des petits constituants de déchets d'abattage étant absorbé dans les constituants de la matière fibreuse et lié par ces constituants de manière à former des corps solides de type granules ou briquettes.
