Description

  The present invention includes, for example, organic processing objects used when drying waste, food processing waste, manure, agricultural and fishery waste, sewage sludge and other waste, processed food raw materials, livestock feed, etc. The present invention relates to a drying processing apparatus.

  For example, household waste, hotels, restaurants, farms, food factories, sewage treatment plants, etc., produce large amounts of organic waste such as garbage, food processing waste, manure, agricultural and fishery waste, and sewage sludge every day. These processes are a problem. These organic wastes contain a large amount of water and generate odors at the same time, so they are difficult to handle during storage and transportation, and can be reused as compost, incinerated, landfilled, etc. It is also difficult to dispose of. Therefore, usually, organic waste is dried and reduced in volume and weight, and then used as compost or incinerated. Conventionally, natural drying by sunlight has been used as a drying means for organic waste, but natural drying has been time consuming and inefficient.

In view of this, an apparatus for mechanically drying organic waste has been proposed in order to increase drying efficiency. For example, Japanese Patent Application Laid-Open No. 2001-105000 discloses an organic sludge drying apparatus. The organic sludge drying apparatus disclosed in Japanese Patent Application Laid-Open No. 2001-105000 heats the periphery of a container containing organic sludge such as livestock manure and food residue with steam and stirs the organic sludge in the container while rotating the spiral blades. As a result, the organic sludge was dried.

As shown in FIGS. 1 and 2, in this embodiment, the container 12 has U-shaped side walls 12 a and a bottom wall 12 b so as to form a bottom surface continuously formed in an arc shape from the side surface. The inner wall structure is long and continuous in the lateral direction (X direction), and is formed by closing both end surfaces in the lateral direction with end walls 12c. The upper surface side of the container 12 is closed by a lid 20 and fixed by a bolt or the like (not shown), and the inside of the container 12 is maintained in a sealed state. The lid 20 of the container 12 can be removed, for example, during maintenance such as cleaning and inspection, and the upper surface side can be opened to facilitate work. The container 12 is supported at a certain height from the ground by a support leg 22 provided with, for example, a metal angle member. An introduction port portion 24 for the waste P is formed in the approximate center on the upper side of the container 12. In the present embodiment, the insertion port portion 24 is formed of a funnel-shaped cylindrical portion projecting upward from the lid 20, communicates with the inside of the container, and can be opened and closed by an opening / closing valve 24 a.

As shown in FIG. 2, the air ejection pipe 44 is provided so as to be ejected radially from a substantially central position of the container, and is efficiently ejected to waste. The ejected air is exhausted out of the container 12 together with the vapor containing malodorous components while drying the waste. In the present embodiment, the compressed air K to be ejected is set to about room temperature. Since the waste is heated by the steam described above, the drying efficiency of the compressed air can be maintained even at room temperature. Note that the air may have an arbitrary temperature equal to or higher than normal temperature, for example, a certain high temperature of about 70 to 90 ° C. In the present embodiment, both ends of the air ejection pipe 44 are pivotally supported at the approximate center of the left and right end walls 12c of the container 12, and are ejected radially while rotating about the axis.

These deodorizing devices and cooling devices can be provided together to prevent malodors, noises, and the like that are generated during the drying process by the drying processing apparatus.

Next, the operation of the organic waste drying apparatus according to this embodiment will be described. For example, steam previously set to 120 to 130 ° C. and 7 to 8 atm is ejected from the steam ejecting means 14 into the container, and room temperature air is ejected from the air ejecting means 18 at a pressure of about 7 to 9 atm, for example. For example, the inside of the container is set to be in a high temperature state of 70 to 80 ° C. An amount of about 12 m ^{3 of} organic waste containing water such as garbage is introduced into the container 12 from the upper side inlet port portion 24. As shown in FIGS. 1 and 2, the waste P in the container 12 is agitated by the cooperation of the steam ejection means 14, the agitation means 16, and the air ejection means 18, that is, the agitation means 16. However, the steam J is spouted to the waste P to heat the waste to easily evaporate the water, and the air K is spouted to the heated waste to remove the water contained in the waste. While evaporating, evaporating water vapor and steam from the steam jetting means are blown out of the waste to promote drying. As shown in FIG. 3, the steam jetting means 14 has a single steam feed pipe 32 arranged continuously in a meandering manner along the side and bottom surfaces of the container. 30 can be distributed and arranged on the entire side surface and bottom surface of the container, and the steam can be uniformly ejected to the agitated waste. Further, the jetted steam heats the waste and at the same time includes a malodorous component in the steam to deodorize the waste. The blade rotation shaft 56 of the stirring means 16 and the air ejection pipe 44 of the air ejection means 18 are combined, and an efficient arrangement configuration can be taken in a limited space in the container. Furthermore, air can be ejected evenly from the substantially central portion of the container so that air is ejected from the agitated waste. Vapor, air, and the like containing malodorous components in the container are forcibly exhausted out of the container by the exhaust device 28 and sent to the deodorizer 62 for deodorization. The gas deodorized by the deodorizing device 62 passes through the cooling device 66 and decreases its temperature and pressure, and is gently exhausted from the exhaust cylinder 72. Therefore, the air exhausted to the outside does not have a bad odor, and the temperature and pressure are lowered, so that the air is quietly exhausted and does not adversely affect the surroundings. The waste is processed by the drying apparatus 10 for about 24 hours, for example, and dried to a powdery state with a moisture content of about 5%, and then the open / close valve of the discharge port 26 on the lower side of the container 12 Open and discharged. The dried waste is effectively reused as compost, for example. Since the malodorous components are removed from the dried waste by the above-described drying treatment, no malodor is generated, and it is easy to handle when storing and transporting. The temperature, pressure, treatment time, etc. of the steam, air, etc. of the drying treatment described above are arbitrary, and are set in accordance with various conditions such as the type of waste to be treated, the state after treatment, or the device configuration. The Note that the drying processing apparatus is not limited to waste drying processing. For example, it is good also as producing livestock feed, a foodstuff, etc. by drying-processing food raw materials etc. using the drying processing apparatus of this invention.

  The organic processing object drying treatment apparatus of the present invention described above is not limited to the configuration of the above-described embodiment alone, and may be arbitrarily selected without departing from the essence of the present invention described in the claims. May be modified. For example, in the above-described embodiment, the configuration of the vapor ejection unit and the air ejection unit may be interchanged.
