Definitions
- the present invention relates to a regenerative thermal waste incineration
- industrial waste sludge, urban waste, food refuse and sewage sludge are disposed of by land filling and/or incineration
- incineration by which the amount of waste can be considerably reduced and little secondary
- fluid bed incinerators have been used to incinerate waste from urban sewage treatment plants, e g , wet waste or sludge
- the fluid bed incinerator is constructed by a cylindrical, fire-resistant (refractory) wall and has its lower part filled with sand 0 used as a fluid medium Air is employed to cause material to be incinerated to float and flow in the fluid medium
- the air is introduced into the sand bed through an outlet of a panel supporting the sand bed at a pressure of approximately 20 to 34 kPa, causing fluidity of the sand bed
- the sand bed is maintained at a temperature of approximately 5 800°C or higher
- the volume of the fluidized sand is increased by approximately 30 to 60%
- the waste is introduced from the lower part of the incinerator If the flow rate of air is high, some of uncombusted waste in the upper part of the incinerator may be discharged into the air with combustion gas
- the flow rate of air is high, some of uncombusted
- the present invention provides a regenerative thermal waste incineration system which can cost-effectively incinerate sludge having a high content of moisture and can prevent generation of incomplete combustibles such as unpleasant odor or carbon monoxide that may cause secondary pollution
- FIG 1 shows a regenerative thermal waste incineration system according to the present invention
- FIG 2 shows a regenerative thermal waste incineration system having a blower at its rear end according to the present invention
- FIG 3 shows a regenerative thermal waste incineration system having a 3-way, automatic openable valve according to the present invention
- FIG 4 shows a regenerative thermal waste incineration system having a
- FIGS 1 and 2 show a regenerative thermal waste incineration system according to the present invention
- the regenerative thermal waste incineration system according to the present invention includes a two-bed regenerative incineration furnace having first and second ceramic layers 105 and 106 for recovering heat from high-temperature gas, third and fourth ceramic layers 107 and 108 for compensating for the temperature of the waste sharply decreasing in the course of drying the waste to keep the incineration temperature at a constant range and accumulating high-temperature heat after incineration, first and second waste inlet valves 109 and 1 1 0 installed at spaces between the ceramic layers 1 05 and 1 07 and between the ceramic layers 106 and 1 08, the two-bed regenerative furnace 1 1 3 having a space enough for complete combustion of combustibles between the ceramic layers 107 and 108 and operating by means of automatically openable valves 1 01 , 1 02, 103 and 1 04 so as to be capable of accumulating and regenerating heat, a blower 1 00 for supplying combustion air, and
- the regenerative thermal waste incineration system having the configuration as shown in FIG 1 operates as follows Combustion air is supplied to the heat-accumulating ceramic layer 1 05 through the valve 101 by means of the blower 100 and pre-heated to a high temperature of 800 to 1200°C
- the valves 101 and 104 are open whereas the valves 102 and 103 are closed
- the wet waste having a high moisture content is supplied to a space between the ceramic layer 1 05 and the ceramic layer 107 through the first waste inlet valve 1 09
- the valve 1 10 for introducing the waste is in a closed state
- the wet waste is separated into vapor and dried waste by hot air passed through the ceramic layer 105
- the temperatures of the combustion air, vapor and waste are raised again while passing through the heat-accumulating, high-temperature ceramic layer 1 07
- the dried waste is burnt and the combustion heat further increases the temperature of exhaust gas, compared to the case of passing through the ceramic layer 107
- the exhaust gas While passing through the ceramic layers 108 and 106, the exhaust gas discharges most of sensible heat into the ceramic layers 108 and 106 cooled l o during previous operation The temperature of the exhaust gas vanes according to the proportion of moisture contained in the waste Thus, heat is supplied from the furnace 1 1 3 to allow the ceramic layers 108 and 106 to have heat enough for subsequent operation
- the first waste inlet valve 109 is closed and untreated waste at a space between the ceramic layer 105 and the ceramic layer 1 07 are completely combusted using hot air passed through the ceramic layer 105 and ash remaining after combustion is allowed to escape This operation is called a forward operation After the forward operation, the valves 101 and 104 are closed and the valves 102 and 1 03
- the second waste inlet valve 1 10 is opened to introduce the waste into a space between the ceramic layer 106 and the ceramic layer 108
- the first waste inlet valve 109 is closed and a backward operation is performed in the same manner as the forward operation The forward and backward operations are repeated
- the ash generated due to incineration is filtered at a cyclone 1 1 1 through the valve 104 via the ceramic layers 107, 108 and 106
- the ash is filtered at the cyclone 1 1 1 through the valve 103 via the ceramic layers 1 08, 107 and 105
- the remaining ash unfiltered at the cyclone 1 1 1 is trapped at the bag filter 1 12
- the exhaust gas is purified to
- the regenerative thermal waste incineration system according to the present invention has a very high heat recovery efficiency by directly heating ceramic packing materials using high-temperature exhaust gas, bringing room-temperature air into contact with high-temperature air to thus regenerate heat, and then drying and incinerating the waste having a high moisture content using the high-temperature air Therefore, extra fuel expenses necessary for incinerating the waste having a high moisture content can be noticeably reduced Also, since the exhaust gas is not brought into direct contact with raw waste after incineration, there is no emission of unpleasant odor from the exhaust gas and secondary pollutants due to incomplete combustion
- Example 1 Wet sludge introduced into the regenerative thermal waste incineration system according to the present invention includes 87% of moisture, 3% of ash and 10% of organic matter represented by C ⁇ HsO ⁇ Clo iNiSo i
- the standard conditions of incineration include 1 tone/hr in feed rate, 850°C in combustion temperature and 5% in radiation loss
- the amount of total emissions from the wet sludge is 5,880 kcal/kg
- the amount of air introduced into the regenerative thermal waste incineration system is 5,000 Nm 3 /hr, a temperature difference ( ⁇ T) between the inlet and outlet of the regenerative thermal waste incineration system is 80°C, and a total amount of exhaust gas is 6,149 Nm 3 /hr
- the total heat capacity needed is 754,000 kcal/hr
- sludge's self-radiation, i e , 588,000 kcal/hr is subtracted therefrom to yield the heat capacity actually needed, i e , 166,000 kcal/hr
- Extra heat capacity in the conventional fluid bed incinerator is calculated as follows
- the amount of air introduced into the conventional fluid bed incinerator is 1 ,600 Nm 3 /hr in the case of 1 3 in air ratio, and a total amount of exhaust gas is 2,793 Nm 3 /hr
