Definitions

  • This invention relates to a waste carbonizing and energy utilizing system, and particularly to a system, comprising a carbonizer and a gasifying fusion furnace, which can be operated at low cost, and which is not affected by variations in the kind of waste to be treated, or by the moisture content of the waste material.
  • Figure 4 shows a waste gasification power generation system disclosed in Unexamined Japanese Patent Publication No. 118124/1999, which is one example of the above-mentioned combustion energy utilization systems.
  • waste 102 is fed from a waste supplier into a fluidized bed gasification furnace 101.
  • Partially oxidized gas, generated in the gasification furnace 101 is sent from a gas discharge port to a cyclone separator 103, in which it is separated into not-yet-burnt char 105, dust 104, and combustible gas 120.
  • the not-yet-burnt char 105 is recycled, as a combustible, into the gasification furnace 101.
  • the dust 104 is processed in an ash fusion furnace in the same way as the not-yet-burnt part.
  • the combustible gas, from which the solid content has been separated, is introduced, through path 120, into a burner 110 through an air pre-heater (not shown) . Part of air heated in the air preheater is sent into the burner 110, and the remainder is sent into an air scattering pipe (not shown) as fluidization air.
  • the combustible gas, sent to the burner 110 through path 120 is burned, and generates combustion gas at a high temperature.
  • the high temperature combustion gas generates steam in a boiler 111, and, after removal of dust by means of a bag filter 114, the gas is released to the atmosphere through a chimney 115 after going through an induced draft fan (not shown) .
  • a bag filter 114 Before the gas reaches the bag filter 114, slaked lime is added from a silo (not shown) to remove salt and reduce acidity.
  • Steam, generated in the boiler 111, generates power by driving a steam turbine 113.
  • a conventional fusion furnace has a high equipment cost due to its complex structure, as well as a high operating cost due to excessive fuel requirements and the need for highly skilled labor.
  • the conventional fusion furnace eliminates dioxin generated from incinerated remainders such as bottom ash or fly ash by adsorbtion into activated carbon or slaked lime. Consequently, wastes containing dioxin have continued to increase and have become a problem.
  • the waste power generating system 100 of FIG. 4 is designed to eliminate burnt ash in the cyclone separator 103, and to supply only gasified gas to the combustion furnace, the uptake efficiency of ash within the cyclone separator is around 90%, and therefore it is unavoidable that some ash will be carried into the boiler 111.
  • the burnt ash contains a large amount of chlorides (NaCl, KCl) and sulfates (Na 2 SO 4 , K 2 SO 4 ), and furthermore, the combustion gas contains a large amount of HCl gas, for example, up to 1000 ppm.
  • HCl gas for example, up to 1000 ppm.
  • Intense high temperature corrosion occurs due to reaction between compounds having a low melting point below 500 degrees Celsius, and HCl contained in the gas within the heat exchanger within the boiler. Therefore, in the conventional waste power generation system the steam temperature is generally set to a low level, e.g. as low as below 400 degrees Celsius. This results in low power generation efficiency.
  • the invention combines a carbonizer and gasifying fusion furnace technology to provide a waste carbonizing and energy utilization system having high efficiency, and enables the utilization of all kinds of waste biomass, including raw garbage with a high moisture content, without producing burnt ash, which is a cause of intense high temperature corrosion,.
  • the waste carbonizing and energy utilizing system in accordance with the invention comprises a carbonizer for producing charcoal by carbonizing waste, a gasifying fusion furnace arranged to receive and burn charcoal produced by the carbonizer, and a heat energy utilizing system, connected to the gasifying fusion furnace, for utilizing heat generated in the operation of the gasifying fusion furnace.
  • a heat path recycles recycling exhaust heat from the heat energy utilizing system to the carbonizer for effecting carbonization of waste therein.
  • a combustion furnace is arranged to receive and incinerate carbonization gas generated from carbonization of waste in the carbonizer, and to introduce the incinerated carbonization gas into the gasifying fusion furnace.
  • the carbonizer preferably comprises a carbonization tank into which waste is introduced, and a jacket surrounding the carbonization tank for receiving a heating medium.
  • the jacket and the interior of the carbonization tank are separated by a wall forming a heating surface within the carbonization tank.
  • Rotating means preferably fins, centrifugally urge the waste against the heating surface.
  • a plurality of carbonizers surround the gasifying fusion furnace.
  • FIG. 1 is a schematic view of a waste carbonizing and energy utilizing system according to the invention
  • FIG. 2(a) is (a) is a cross-sectional view of a carbonizer
  • FIG. 2(b) is an enlarged cross-sectional view of a part of the carbonizer
  • FIG. 3 is a schematic view of a conventional carbonizer
  • FIG. 4 is a schematic view of a conventional waste gasifying power generating system.
  • the waste carbonizing and energy utilization system 10 comprises a carbonizer 20, a gasifying fusion furnace 30 and a heat energy utilization apparatus 40, which, in the embodiment described, is a power generating plant.
  • the carbonizer 20 carbonizes waste to generate charcoal, the gasifying fusion furnace 30 burns the charcoal, and the power generation plant 40 utilizes the heat generated from the incineration to generate power.
  • the system's operating cost is reduced by using the exhaust heat from the power generating plant for carbonization in the carbonizer 20.
  • the waste which is collected by appropriate means, and may contain fluids or plastics, is fed from a waste supply hopper 50 into the carbonizer 20.
  • the waste In the carbonizer 20, the waste is dried and then carbonized.
  • the carbonized waste is then fed into the gasifying fusion furnace 30.
  • a plurality of carbonizers 20 may be provided, in surrounding relationship, around one gasifying fusion furnace 30, and the waste which is converted to charcoal in the carbonizers is supplied from each of the carbonizers to the gasifying fusion furnace 30.
  • Carbonization gas which is organic gas generated in the process of carbonization in the carbonizers 20, is incinerated within combustion furnaces 24, and then introduced into the gasifying fusion furnace 30.
  • the reason for providing plural carbonizers around one gasifying fusion furnace is that carbonization is a batch process that typically takes place over an interval of from forty to sixty minutes. By feeding and discharging the several carbonizers in succession, the fusion furnace can be operated more smoothly, and smoother generation of power can be achieved.
  • the carbonized waste combusts explosively within the gasifying fusion furnace 30, and the temperature inside the furnace 30 can reach a level typically from 1250 to 1500 degree Celsius. In a lower part of the furnace, where carbide is combusted, the temperature can exceed 1500 degrees Celsius.
  • power is generated by operation of a steam turbine in the power generation plant 40.
  • the waste gas emitted by the power generation plant is recycled for carbonization in the carbonizers 20.
  • the temperature of the gas introduced into the power generation plant 40 is typically from 1100 degrees Celsius to 1500 degrees Celsius, but the temperature of the exhaust heat recycled for carbonization is about 600 degrees Celsius.
  • the temperature of the exhaust gas from the carbonizers is lowered to about 200 degrees Celsius by a desuperheater 60, and the gas is released to the atmosphere from a chimney 80 after passing through a dust collector 70.
  • the carbonizer 20, as shown in FIG. 2(a), can be an apparatus such as that disclosed in my United States Patent 6,379,629, dated April 30, 2002, the entire disclosure of which is incorporated by reference.
  • the carbonizer comprises comprising a carbonizing tank 22, and a jacket 28, to which a heating medium is supplied as a hot blast.
  • a carbonizing tank heating surface 26, and optionally other inner surfaces, are heated by the heating medium.
  • Carbonization gas Y (FIG. 1), which is organic gas generated within the carbonizing tanks 22, is incinerated in combustion furnaces 24, and then introduced to the gasifying fusion furnace 30.
  • the heating medium heating the carbonizing tank heating surface 26 is a hot blast of exhaust or hot blast gas H from the heat energy utilization device 40.
  • This exhaust gas arrives at the carbonizers at a temperature of around 600 degrees Celsius. After flowing through the carbonizing tank jackets 28, the gas is delivered to desuperheater 60, in which its temperature is reduced to around 200 degrees Celsius, and is released to the atmosphere from chimney 80 after passing through dust collector 70.
  • An important characteristic feature of the carbonizers 20 is the rotating fins 21 provided on the central lower part of the main body. As a result of the operation of the rotating fins, waste is pushed against the heating surface 26 of the carbonizing tank, and is pushed upward along surface 26, forming a thin film as shown in FIG. 2(b). Waste with a higher moisture content is preferentially pressed against the carbonizing tank heating surface 26 by centrifugal force. Waste which is heated, and has a reduced moisture content, moves to vaporization surfaces 23, which enhance vaporization.
  • the whole heating surface is utilized, the carbonizing tank heating surface 26 and the vaporization surface 23 being almost equal in area.
  • the contacting circumferential speed is as fast as 5 to 15 m/s, and therefore thermal efficiency improves by up to 4 to 6 times compared with that of the prior art.
  • the carbonizer 20 can rotate fluids such as slurries, causing them to contact the carbonizing tank heating surface 26 in the form of thin film.
  • the inside of the carbonizing tank 22 is kept essentially oxygen-free (the oxygen content being maintained at a level less than 1%). Therefore, no oxidation reaction takes place even when polyvinyl chloride, etc. is heated to 400 to 450 degrees Celsius.
  • Chlorine bonded with polyvinyl chloride, or hydrogen bonded with benzene, are separately gasified respectively, and introduced to the combustion furnace 24.
  • the channel to the combustion furnace 24 is also oxygen-free and carbon monoxide-free, and thus little oxidization takes place. Under these conditions, chlorides and hydrogen are instantly incinerated in the combustion furnace 24 at a temperature higher than 800 degrees Celsius, and no carbon monoxide is produced. Moreover, almost no dioxin is produced.
  • the temperature inside the gasifying fusion furnace 30 is kept at a level as high as 1250 to 1500 degrees Celsius, even if dioxin is produced at any stage of the process, it will be decomposed and rendered harmless.
  • the system according to the invention operates with high efficiency and at a low operating cost.
  • FIG. 1 shows single stage carbonizers
  • FIG. 2 shows a two stage carbonizer
  • a cooler 90 is provided underneath the gasifying fusion furnace 30.
  • the cooler has a similar structure to that of the carbonizer 20. Ash is produced in the cooler, after a slug formed by burning and melting charcoal is cooled down and collected. The volume of this waste is low in comparison with that of the waste thrown into the first stage.
  • the waste discharged from the cooler may be utilized as roadbed material, for example.
  • the system according to the invention can solve a variety of problems such as the protection and effective utilization of natural resources, conservation of energy resources and protection of the environment, especially because it can utilize all kinds of waste biomass, including raw garbage having a high water content.
  • the heat energy produced by the system may be utilized not only for power generation, but also for other purposes, such as operation of air-conditioning systems, etc.
  • the terms "comprises” and “comprising” and variations thereof mean that the specified features, steps or 5 integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
