Description

In the present invention, a mass of plant biomass containing a lot of water is crushed, chipped and dried to a low water content in the mixing / drying operation, and then the raw material is dried by the combustion gas from the combustion device The present invention relates to a device capable of generating hot water by using the fuel and supplying hot air into the greenhouse and greenhouse.

Although a rotating blade shaft is provided in the storage hopper to increase the fluidity of stored items containing a large amount of moisture, it is not suitable for substances with high tackiness, and sticks to the rotating shaft / blade. It is difficult to remove the material between them. The rotating shaft may stop. There are various proposals for this. At present, sufficient results have not been obtained for the biomass fuel bodies with high moisture content in the crushing and scraping machine during drying.

A large amount of waste material is generated in the process of processing wood. Waste wood is generated in large quantities, such as planar waste generated by cutting wood, a mixture of various waste materials, waste containing pulverized waste such as MDF and particle board, and scraps obtained by crushing wood pieces and skins. These woody biomass is actually incinerated and discarded, and the heat energy generated when incinerated and discarded is not effectively used.

On the other hand, natural wood has a unique beauty and texture of natural wood that cannot be obtained with metal or plastic, but if it is used in an undried state, it will deform and become distorted over time, Or there is a defect such as shrinkage to form a gap. This drawback allows the wood to be sufficiently dried to reduce gaps. However, in order to sufficiently dry the wood, it is necessary to leave it for a long period of time or to remove moisture by heating. Although the method of forcibly removing moisture can be dried in a short time, it consumes a large amount of heat energy, and thus has a drawback of increasing running costs.

For the purpose of reducing the running cost of drying wood, a drying method has been developed that effectively uses thermal energy generated when wood-based biomass containing moisture is burned (see Patent Document 1).

In this document, there is a furnace in the floor of the fireproof room, a pedestrian part of raw wood in the center of the room, a convection blower installed in an appropriate place in the room, and a temperature sensor arranged in the center of the room and wood, Inside, waste materials such as wood scraps, demolition materials or wood fragments are put as combustion materials, and the surface is covered as waste materials such as planar waste, canna waste, bark or waste paper, etc., and the lid of the furnace is covered and after ignition Adjusts the air inside the furnace by adjusting the air in the exhaust duct, etc., adjusts the room temperature to a range of 75 to 80 ° C., and circulates smoke and hot air in the convection blower to reach the drying target wood and the outside air temperature. Accordingly, there is described a method for drying smoke from wood comprising a step of drying at low temperature smoke for about 3 to 5 days and leaving it until the difference between the room temperature and the outside temperature and the temperature at the center of the wood is within 8 ° C.

2. Description of the Related Art Conventionally, an externally heated drying furnace or incinerator for drying other water-containing organic waste such as chicken manure, livestock manure, and household waste is known. There has also been a proposal to use a combustion gas from an incinerator as a heat source for a dry carbonization furnace by combining a drying furnace and an incinerator. (See Patent Documents 1, 2, and 3.)

The plant waste containing 50% or more of the water was mostly used for compost, but there is no information on the combustion method as the reuse of fuel for drying regarding this highly water-containing plant waste. In particular, regarding the reuse of plant waste, little is known to use it as a heat source or steam for combustion.

The method of using heat generated from hydrous woody biomass is a method in which woody biomass is burned in a combustion furnace, and the water is heated with the heat energy that is burned to make warm water. In a hot water generator using dry-combustion treatment, which uses a compacted body of hydrated wood chips as a moisture-containing biomass fuel, heat exchange between the moisture-containing biomass fuel storage unit, a fuel supply unit capable of quantitatively supplying the fuel, and a combustion unit There has been proposed a continuous hot water producing apparatus using wood chip biomass composed of a hot water generator and a hot water storage unit as fuel (see Patent Document 4).

The hot water circulation means is a hot water circulation pipe or a hot water circulation groove, preferably installed so that the embedding depth is 50 to 150 cm, and when the hot water circulation pipe is used, the hot water circulation pipe should be installed so as to reduce the gap between them. Has been proposed (see Patent Document 5).

In areas where bamboo forests are owned, the energy consumed by agricultural facilities such as greenhouses and greenhouses that were previously supplied with fossil fuels and electricity is converted into bamboo products that are local products. Bamboo chip manufacturing means to pulverize bamboo material into bamboo chips, and hot gas to burn bamboo chips manufactured by bamboo chip manufacturing means, in order to realize self-sufficiency in reducing air pollution and energy costs A plantation system using bamboo biomass including a generating combustion furnace and agricultural equipment such as a greenhouse using hot air generated by a hot gas generating combustion furnace as a heat source.

By using a fertilizer made by composting husk, young bamboo, and parent bamboo for the culture medium of this greenhouse, products from bamboo forest can be used (see Patent Document 7).

However, nothing is used for heating a greenhouse due to combustion with biomass fuel containing a large amount of moisture.

When processing highly viscous bulk waste with high water content vegetable waste with a moisture content of 50% or more, a conveyor such as a discharge screw conveyor, a conveyor with vertical plates for extrusion, a bread conveyor, a scraper conveyor, etc. at the bottom of the storage hopper In a storage hopper that stores waste, if a large amount of bulk material is deposited in the hopper, the material is discharged to the crushing, stirring / cutting, and scraping device when heat treatment is performed. In addition to the load for carrying out the process, the weight of the deposited material is added as an extra load, and sufficient agitation / discharge processing cannot be performed.

In the present invention, it is important to have a dry stirring vessel and a heat treatment apparatus that can hold a vegetable waste material having a certain amount of viscosity in the middle of the pre-combustion in such a mass with a lot of moisture. With the object of providing an apparatus that solves the above-mentioned problems, in particular, when recycling waste plant materials that contain a large amount of moisture of 50% or more and are in a massive state, in a sufficiently close state after pulverization Establish drying with exhaust gas that can be processed into hot plant waste that becomes an effective combustion raw material by heat treatment methods such as treatment with hot air such as exhaust heat that can be dried to uniformly reduce moisture to 20% or less And it aims at finishing to the combustion apparatus which can be taken for combustion in an appropriate state.

In particular, when substances that generate harmful substances such as dioxins are included when burning high-moisture waste vegetable fuel, there is a disadvantage that harmful substances contained in exhaust gas cannot be incinerated at high temperatures. Furthermore, since it is necessary to use high-moisture plant waste material as a combustion material in a specific state, adding high-moisture plant waste material fuel containing a lot of water will raise the temperature in the combustion furnace to a high temperature. It is extremely difficult to control the amount of fuel to be introduced.

Furthermore, the method described in the above literature uses only the heat energy generated when burning high water content vegetable waste in a small combustion furnace for drying wood, so other combustion, heating fuel, etc. It cannot be used effectively for the purpose. There are few proposals of small-sized combustion furnaces with high-moisture plant waste fuel containing a large amount of water.

The present invention has been developed for the purpose of solving such drawbacks. A high water content plant waste material that dries plant waste material chips into fuel before combustion by effectively using the thermal energy generated by burning 50% or more crushed high water content plant waste material fuel In addition to being extremely economically dried and usable as fuel, the heat generated from the high-moisture vegetable waste fuel generated from fuel chips while drying and controlling the moisture-containing and high-humidity plant waste material to an ideal temperature It is to provide usage.

In addition, the thermal energy generated when burning high-moisture plant waste is reduced, and the temperature of the greenhouse that grows plants in agricultural greenhouses by effectively using it as fuel is controlled, making it an ideal environment Another object of the present invention is to provide a method for utilizing heat generated from a high-moisture plant waste material that can be warmed and a steam generator.

Further, in the conventional apparatus, the high-moisture plant waste material fuel has a high water content and is also a highly viscous lump, so that a large amount of fossil fuel is required for processing. We have been studying the use of high-moisture plant waste material fuel that contains water as a heating fuel for greenhouses, greenhouses, etc., but sufficient methods, equipment, and steam generation systems and heating systems are provided. It has not been.

In order to contribute to resource saving and pollution-free (environmental conservation), the present inventor pre-heated high-moisture plant waste materials in the form of chips. The purpose is to develop a system to dry and use as a hot water fuel for agricultural facilities while circulating a heat source as an effective high water content vegetable waste fuel.
