Definitions

  • the present invention relates to an oil temperature dehydration treatment method for treating waste that is fluid due to excessive moisture, such as sludge, sugar and starchy residues.
  • an oil temperature dehydration method is known in which oil to be dehydrated (hereinafter, dehydrated oil) is heated to introduce waste and evaporate the water (Patent Document 1). And Patent Document 2).
  • the oil temperature dehydration method uses an oil temperature dehydration apparatus (cooker) composed of a dehydration container for storing heated dehydrated oil, and throws waste into the heated dehydrated oil, and uses a stirring blade or a feed screw. Moisture is removed from the waste to be transferred while stirring. Since the waste after treatment contains oil instead of moisture, for example, inorganic waste is reduced in volume through deoiling treatment and landfilled, and organic waste is diverted to biomass fuel, fertilizer or feed .
  • Patent Document 3 a sludge thrower that throws fluid waste into a dewatering container is provided with a perforated member that disperses the waste in a number of strings and pushes it out so that the waste can be turned upside down. It is dispersed in a string so that it can be immersed in dehydrated oil (Patent Document 3, [0006]).
  • the waste dispersed in a string has an advantage that the dehydration time is shortened because the specific surface area is large (Patent Document 3, [0007]).
  • the oil temperature dehydration method includes dehydrated waste containing oil instead of moisture, so it can be used for crushing dehydrated waste, centrifuge processing that centrifuges dehydrated waste, and centrifugal separation that gives centrifugal force to the dehydrated waste. Deoiling treatment is required. In any deoiling treatment, if the oil remaining in the dehydrated waste is uniformly dispersed, the oil can be removed from the entire waste to the same extent.
  • the dehydrated waste is partly agglomerated or partly subdivided, and the agglomerated or subdivided constituent units of the waste (subdivided units constituting the waste,
  • the shape or size of the particles of the object or the block of the lump) is not uniform, the degree of deoiling is different for each structural unit, and it is difficult to uniformly deoil the entire waste.
  • the oil temperature dehydration treatment method disclosed in Patent Document 3 has a fluid waste with a string-like structural unit having different lengths and uniform deoiling treatment.
  • the string-like structural unit is divided during the dehydration treatment, if the structural unit is short, it is considered that there are some that are completely pulverized and part of the structural unit becomes a granular material.
  • the constituent units that have become powder particles in this manner are difficult to deoil and have a problem that the remaining oil content increases.
  • the oil temperature dehydration method disclosed in Patent Document 3 is considered to be unable to remove sufficient oil content because the string-like constituent unit and the constituent unit that has become a granular material are mixed and pressed.
  • the oil temperature dehydration method disclosed in Patent Document 3 can be evaluated for increasing the specific surface area in order to efficiently dehydrate fluid waste, but is subject to dehydration and deoiling treatment. Since the constituent unit becomes a string shape that is easily divided, the shape or size of the constituent unit that is actually dehydrated and deoiled varies, and a problem remains particularly in the deoiling treatment. Therefore, an oil temperature dehydration method that can efficiently dehydrate fluid waste and uniformly and sufficiently remove oil in the deoiling process was studied.
  • What has been developed as a result of the study includes a preparation step for adjusting oil content in fluid waste in an oil temperature dehydration method in which waste is poured into heated dehydrated oil to evaporate moisture.
  • a molding process that makes waste with adjusted oil content the same shape and size a primary dehydration process that puts the molded structural unit into heated dehydrated oil and dehydrates it without stirring, and dehydration
  • An oil temperature dehydration treatment method has been developed, in which the treated structural unit is put into heated dehydrated oil, followed by a secondary dehydration step in which dehydration treatment is performed while stirring.
  • the oil content of the fluid waste is adjusted by the preparation step so that the waste can be divided and molded into a predetermined shape, and the waste is formed in the same shape by the molding step. Then, it is divided and molded into structural units of a size, and the surface of the structural unit is mainly dehydrated by the primary dehydration process to prevent the deformation, and the structural unit is completely dehydrated by the secondary dehydration process. Since the structural units have the same shape and size, they are equally dehydrated and deoiled. From this, the entire waste is uniformly dewatered and deoiled.
  • oil is added to fluid waste to add viscosity, and it is divided into a predetermined size (amount) and molded into a structural unit retained in a predetermined shape.
  • the oil content in the waste is added separately, with 25 vol% to 30 vol% as a guide.
  • the added oil is preferably the same as the dehydrated oil. Thereby, in the dehydration step, it becomes the same as that the dehydrated oil quickly penetrated into the waste, and the dehydration time can be shortened.
  • the fluid waste contains an oil content exceeding 30 vol%, the oil content is not added.
  • the waste whose oil content has been adjusted is sufficiently kneaded to have a viscosity that exhibits shape retention.
  • the structural unit In the molding process, waste with viscosity that exhibits shape retention is divided and molded into structural units of the same shape and size. As long as the structural unit is the same shape, the outer shape is free and can be of any size. However, the structural unit with a complicated shape is missing and easily generates powder, and if it is too large, dehydration or deoiling is performed. However, if it is too small, the structural unit itself becomes a granular material. From this, the structural unit may be a pellet, more specifically, a pellet having the same outer diameter and length.
  • the “pellet” referred to in the present invention is a cylindrical body having an outer diameter and a length of about several millimeters to several tens of millimeters. The outer diameter and length of the pellets may be different, but it is preferable that both are equal.
  • the pellet which is a cylindrical body
  • the primary dehydration process described later to prevent the collapse of the shape
  • the pellets have the same outer diameter and length, the distance from the surface to the center will be the same in most parts, so there will be no bias in the permeation of oil in the dehydration process, and a uniform dehydration process will be realized in a short time. Is done.
  • various conventionally known pellet molding apparatuses can be used. When pellets are molded, if the waste or pellets are heated to evaporate even a little, the shape retention of the pellets is improved.
  • the structural unit In the primary dehydration step, the structural unit is put into heated dehydrated oil and dehydrated without stirring, whereby the surface of the structural unit is dehydrated to prevent deformation. As a result, the surface of the structural unit is cured and the viscosity is not observed, so that the structural units do not stick to each other, and block formation of the structural units can be prevented.
  • the structural unit whose surface is hardened in the primary dehydration step is completely dehydrated by putting it into dehydrated oil and heating it with stirring. Since the surface of the structural unit is cured, there is no possibility that the structural unit will be deformed by stirring.
  • the structural unit after the secondary dehydration step is deoiled by various conventionally known deoiling means.
  • the squeezing treatment may break down the structural unit and make the structural unit into a powder. Therefore, the deoiling step suitable for the present invention is a deoiling step of deoiling the dehydrated constituent unit by centrifugation.
  • the structural unit after the dehydration process is not lost.
  • the structural unit determined in the first molding step can be used as a final product as it is. This means that, for example, when the structural unit is a cylindrical pellet, the final product is also a pellet.
  • the present invention provides an oil temperature dewatering method that can efficiently dehydrate fluid waste and uniformly and sufficiently remove oil in the deoiling process. This is an effect obtained by subdividing the waste into structural units having a uniform shape and size by adjusting the viscosity. Further, a structural unit having a uniform shape and size is prevented from being deformed by performing a dehydration process in a secondary dehydration step after a primary dehydration step of curing the surface. Such prevention of shape deformation enables dehydration treatment of a structural unit having a uniform shape and size.
  • the structural unit can be made into a final product as it is, so if the waste is made into pellets in the molding process, the deoiling process is finished and A final product of pellets can be obtained.
