Description

  The present invention relates to a garbage carbonizing apparatus that heats and garbage carbonizes garbage under a low oxygen concentration.

  Conventionally, a garbage carbonization apparatus for carbonizing garbage is known. In this type of equipment, the garbage is heated to a certain temperature or more and thermally decomposed (dry distillation) in a state where oxygen is cut off or restricted in the carbonization chamber, so that the garbage is finally reduced in volume and volume. Change to solid, ie carbide. In the process of carbonization of garbage, first, moisture evaporates, and then the organic matter is decomposed as the temperature rises to generate gas containing various combustible gases (dry distillation gas). Eventually, carbon-based charcoal is generated. This charcoal can be used as an adsorbent or a soil conditioner. Garbage carbonization equipment can in principle treat wood, oils and fats, and plastics. The treatment by carbonization has fewer restrictions on the quality of the treated product compared with the garbage treatment methods such as composting and drying volume reduction.

On the other hand, the dry distillation gas generated in association with the carbonization treatment may contain harmful substances and is usually burned by a combustion device and discharged. The relationship between the carbonization temperature and the generated carbonization gas greatly depends on the components of the object to be treated. For a typical dry distillation gas, the combustion reaction is as follows. _{Methane: CH 4 + 2O 2 = CO} 2 + 2H 2 O, _{CO: 2CO + O 2 = 2CO 2} , _{hydrogen: 2H 2 + O 2 = 2H} 2 O. Thus, oxygen (air) is required for combustion of dry distillation gas, and the required amount is theoretically determined according to the amount of gas (theoretical air amount).

  In actual combustion, the air volume is supplied at a constant magnification (air ratio) of the theoretical air volume to prevent incomplete combustion by preventing shortage of combustion air, and to discharge air pollutants such as unburned gas and dust. It is preventing. Moreover, when the garbage carbonization apparatus is positioned as a waste incinerator, it is necessary to maintain the gas combustion temperature at, for example, 800 ° C. or more from the viewpoint of suppressing the generation of dioxins.

  As described above, the dry distillation gas generated in the process of carbonizing the garbage needs to be reliably burned at a predetermined temperature or higher and then discharged to the outside air. By the way, in the carbonization processing apparatus using a commercial power source as a power source, even when the commercial power supply fails during operation of the carbonization processing apparatus, the dry distillation gas and the high-temperature burned gas are quickly exhausted outside the apparatus to obtain a high concentration. It is necessary to avoid the accumulation and filling of harmful gases, and to avoid the danger of explosion due to combustible gases.

Therefore, an emergency power supply that supplies power during a power failure of the commercial power supply and an emergency blower that is driven by this emergency power supply are provided. 2. Description of the Related Art A waste heat treatment apparatus that is discharged directly into the atmosphere is known (see, for example, Patent Document 1).
JP 2001-153342 A

  However, in the countermeasures for gas discharge at the time of a power failure of the commercial power supply as shown in Patent Document 1 described above, the combustion gas in the furnace is discharged directly into the atmosphere without going through the heat exchanger, so the high-temperature combustion gas There is a problem that the emergency blower is easily damaged, and a repair cost is required when the emergency blower is damaged. If the emergency blower has a heat-resistant structure that can withstand such a high temperature, there is a problem that the cost increases.

  In addition, in a relatively small-scale garbage carbonization device that carbonizes garbage using a commercial power source as a power source, it is a low-temperature device that can safely and efficiently exhaust high-temperature gas after combustion during normal operation as well as during a power failure. It is desirable to provide a smaller gas exhaust device at a lower cost.

  This invention solves the said subject, and aims at providing the garbage carbonization apparatus which can exhaust the waste gas which burned dry distillation gas safely and efficiently.

  In order to achieve the above object, the invention of claim 1 includes a container for storing garbage, a carbonization means for heating the container and carbonizing the garbage stored in the container, and the carbonization process. A garbage carbonization apparatus comprising: combustion means having a combustion chamber for heating and burning the gas generated in the gas; and exhaust means for exhausting the gas burned by the combustion means. The means includes cooling means for diluting and cooling the burned gas by taking in outside air, and a blower for sucking and exhausting the gas diluted and cooled by the cooling means.

  According to a second aspect of the present invention, in the garbage carbonization apparatus according to the first aspect, a preliminary blower driven by a preliminary power supply is disposed in series with the blower.

  According to a third aspect of the present invention, in the garbage carbonizing apparatus according to the first aspect, a spare blower driven by a spare power source is disposed in parallel with the blower.

  According to a fourth aspect of the present invention, there is provided the garbage carbonizing apparatus according to the third aspect, wherein an ejector for preventing a backflow is disposed at a confluence portion on the downstream side of the blower and the preliminary blower.

  According to a fifth aspect of the present invention, in the garbage carbonizing apparatus according to the fourth aspect, the ejector forms a silencer.

  According to a sixth aspect of the present invention, in the garbage carbonization apparatus according to the fourth or fifth aspect, the ejector includes a drive gas pipe and a suction gas pipe provided so as to surround the drive gas pipe substantially coaxially. The driving gas pipe is connected to the preliminary blower, and the suction gas pipe is connected to the blower.

  According to the first aspect of the present invention, the cooling means and the blower are provided, and the diluted and cooled gas is sucked and exhausted. Therefore, the blower can be prevented from being damaged by the high-temperature gas, and the carbonization treatment in the carbonization means is performed. By keeping the space from the space to the cooling means at a negative pressure, the gas generated in the garbage carbonizing apparatus is prevented from leaking to an external space outside the predetermined range, and the exhaust gas can be exhausted safely and efficiently.

  According to the second aspect of the present invention, since the spare blower driven by the spare power source is provided, the dry blower gas and combustion are performed by the spare blower even if there is a power failure or a failure of the blower (normally operating blower, hereinafter referred to as main blower). By exhausting the later gas, it is possible to avoid the danger of explosion due to the high concentration of harmful gases and flammable gases. By setting the position of the preliminary blower arranged in series with the main blower on the downstream side of the cooling means, it is possible to prevent the preliminary blower from being damaged by the high temperature gas.

  According to the invention of claim 3, even if there is a power failure or failure of the main blower, the reserve blower exhausts the dry distillation gas and the gas after combustion to reduce the risk of explosion due to high concentration of harmful gases and flammable gas. Can be avoided. Since the position of the preliminary blower arranged in parallel with the blower is downstream of the cooling means, it is possible to prevent the spare blower from being damaged by the high temperature gas. In addition, since the spare blower is arranged in parallel with the main blower, the amount of exhaust gas passing through the spare blower is small when the spare blower is stopped, and the spare blower is stopped during normal operation when there is no power outage. The life of the blower can be extended. Also, for example, if the spare blower is operated even during normal operation, a more stable dry distillation gas can be obtained by securing a larger air volume than in the case of operating the main blower alone and expanding the control range of the combustion conditions in the combustion chamber. Can be burned.

  According to the invention of claim 4, even if one of the main blower and the spare blower is stopped and the other is operated independently, the exhaust gas can be prevented from flowing backward to the stopped blower side by the ejector, and the adverse effect due to the exhaust gas reverse flow Prevention and longer life of the blower. This ejector does not need to have a complete pump function by a so-called ejector, and may have a structure having at least a backflow preventing function.

  According to the invention of claim 5, the backflow prevention function of the ejector and the silencer function can be realized by one device, and a quiet and small garbage carbonizing apparatus can be realized at low cost.

  According to the sixth aspect of the present invention, in the normal exhaust during a non-power failure, the exhaust gas can be efficiently exhausted by the main blower using the outer suction gas pipe having a small pipe resistance in the so-called ejector structure. Further, at the time of a power failure, the exhaust gas can be efficiently exhausted without generating a back flow of the exhaust gas by the driving gas pipe and the auxiliary blower provided inside the double pipe.

  Hereinafter, a garbage carbonization apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a garbage carbonizing apparatus 1 of the present invention. The garbage carbonization apparatus 1 is a substantially vertical apparatus that uses electric power as a power source. From the bottom, the carbonization section 2, the combustion section 3 that combusts the dry distillation gas thereon, and the combustion-treated gas is exhausted thereon. And a control unit 5 that receives power supply from outside and controls the carbonization unit 2, the combustion unit 3, and the exhaust unit 4 to perform processing from carbonization to exhaust. The garbage carbonizing apparatus 1 includes a container 11 that accommodates the garbage 10, and the carbonization unit 2 heats the container 11 to carbonize the garbage 10 stored in the container 11. Details will be described below.

  The carbonization part 2 includes a heat insulating wall 20a and a front door 20b to form a sealed space (carbonization chamber), and a carbonization heater 21 that inputs energy for carbonization into the sealed space, and garbage during carbonization. Two thermometers T1 and T2 for measuring the temperature are provided. The heat insulating wall 20 a includes a communication duct 60 that communicates with the combustion unit 3 from the sealed space. The front door 20b includes a proximity switch SW for confirming the open / closed state of the front door 20b, and a solenoid lock SL for preventing unsafe opening and closing of the front door 20b to prevent danger and ensuring a reliable sealing. It has. The container 11 is opened in the sealed space by opening the front door 20b in a state where the garbage 10 or the treated carbide is accommodated therein, or is taken out of the sealed space. The thermometers T1 and T2 are disposed in the vicinity of the container 11. The communication duct 60 is connected to the inside of the container 11, and sends out gas (dry distillation gas G <b> 1) generated in the carbonization process inside the container 11 toward the combustion unit 3.

  The combustion unit 3 is in a state where it is insulated from the outside air by the heat insulating wall 30, the dry distillation gas path 61 connected to the communication duct 60, the combustion heater 31 formed in a coil shape so as to surround the dry distillation gas path 61, and the dry distillation gas path Combustion catalyst 32 provided on the downstream side of 61, and thermometers T4, T5, T6 provided respectively in the approximate center of dry distillation gas path 61 and in front of and behind combustion catalyst 32, respectively. The dry distillation gas path 61 guides the dry distillation gas G1 from the carbonization part 2 to the exhaust part 4 while burning it. That is, the dry distillation gas path 61 is a combustion chamber that heats and burns the dry distillation gas G1 generated during the carbonization process.

  Moreover, the garbage carbonization apparatus 1 has air pipes 70 to 73 communicating with the combustion unit 3 and the exhaust unit 4. Among these, the air pipe 71 is connected to the inlet side of the dry distillation gas path 61 and supplies combustion air A <b> 1 to the dry distillation gas path 61. The air pipe 71 is branched from an air pipe 70 having an outside air intake port below the apparatus. A thermometer T8 for measuring the outside air temperature is provided near the outside air inlet of the air pipe 70. In addition, the air pipe 71 includes an inlet thermometer T3 that measures the combustion air temperature at the inlet of the combustion unit 3.

  The exhaust section 4 is connected in parallel via a pipe 63 to the downstream side of the dilution cooling chamber 41 connected to the combustion gas pipe 62 and the air pipe 72 connected to the outlet side of the dry distillation gas path 61 and the dilution cooling chamber 41. A main blower 42 and a spare blower 43, a silencer 44 provided at a junction of downstream pipes 64 and 65 of the blowers 42 and 43, and an exhaust pipe 45 connected to the silencer 44 are provided.

  The dilution cooling chamber 41 is a place for diluting and cooling the gas G2 by mixing outside air with the burned gas G2 flowing from the combustion section 3 through the combustion gas pipe 62. The air pipe 72 is a pipe branched from the air pipe 70, takes in outside air, and supplies it as cooling air A <b> 2 to the dilution cooling chamber 41. The dilution cooling chamber 41 includes a thermometer T7 for monitoring the cooling effect. In addition, the other air piping 73 branched from the air piping 70 is also connected also to the inside of the exhaust pipe 45, and the air for cooling and dilution can also be introduce | transduced here.

  The main blower 42 sucks and exhausts the gas G3 after being diluted and cooled in the dilution cooling chamber 41. The auxiliary blower 43 is normally stopped, and is driven by an auxiliary power source (not shown) in an emergency such as a power failure to perform emergency exhaust.

  Next, operation | movement of the garbage carbonization apparatus 1 is demonstrated along the flow of dry distillation gas G1. In the carbonization unit 2, the garbage 10 stored in the container 11 is heated from the outside of the container 11 by the carbonization heater 21 in an oxygen-free state or an anoxic state, and the dry distillation gas G <b> 1 is generated from the heated garbage 13. appear. The dry distillation gas G1 is guided to the dry distillation gas path 61 of the combustion unit 3 through the communication duct 60. The one-way flow of the dry distillation gas G1 is formed by the positive pressure accompanying the generation of the dry distillation gas G1 and / or the negative pressure by the main blower 42.

  The dry distillation gas G1 guided to the dry distillation gas path 61 is heated by the combustion heater 31 in the dry distillation gas path 61, mixed with the combustion air A1 supplied from the air pipe 71, and passes through the dry distillation gas path 61 and the catalyst 32. It is burned during. The combusted gas G2 is mixed with the cooling air A2 supplied from the air pipe 72 in the dilution cooling chamber 41 via the combustion gas pipe 62 connected to the dry distillation gas path 61 to be diluted and cooled. The diluted and cooled gas G3 is discharged into the atmosphere as exhaust gas G4 through the main blower 42, the silencer 44, and the like. The control unit 5 controls each unit to perform a series of these processes.

  Next, with reference to FIG. 2 to FIG. 5 in addition to FIG. 1, a modified example of the exhaust part 4 in the garbage carbonizing apparatus 1 of the present invention will be described. FIG. 2 shows a basic apparatus configuration focusing on gas flow. The exhaust section 4 (right side of the combustion section 3 in the figure) of this apparatus configuration includes at least two of a dilution cooling chamber 41 and a blower 42 which are basic components of the exhaust section 4. The dilution cooling chamber 41 (cooling means) becomes negative pressure due to suction by the blower 42, whereby air A2 is taken into the dilution cooling chamber 41 from the air pipe 72, and the burned gas G2 from the pipe 62 is diluted and cooled. Is done. The blower 42 sucks the gas G3 after being diluted and cooled in the dilution cooling chamber 41, and discharges it as the exhaust gas G4 via the pipe 64.

  Here, the exhaust means is the blower 42 that sucks and exhausts the exhausted gas, and that the intake of the air A2 into the dilution cooling chamber 41 is not the push type but the suction type, the garbage carbonizer 1 It is important for safety. In such a configuration, the pressure of the carbonization unit 2 does not become a positive pressure due to the operation of the blower 42, and even if the exhaust path is blocked, the backflow of air to the carbonization chamber due to the operation of the blower 42 Does not happen. In addition, since a design restriction on the pressure loss (exhaust resistance) on the exhaust side (downstream side of the gas flow) of the blower 42 is relaxed, it is easy to install a silencer or the like.

  3 and 4 show an apparatus configuration in which a spare blower 43 that is driven by a spare power source is connected in series or in parallel to the main blower 42, respectively. The preliminary blower 43 is normally kept in a stopped state, and is operated when the main blower 42 is stopped by stopping the power source or the like. For example, if the AC commercial power supply is stopped when the main blower 42 is operated by the AC commercial power supply, the standby blower 43 is operated by the standby power supply. As a reserve power source, a power source different from the power source for the main blower 42 such as a battery or a generator is used.

  When the preliminary blower 43 is arranged in series as shown in FIG. 3, equipment such as a switching damper that switches the exhaust path according to the operating state of the two blowers is unnecessary, and the pipe path is configured reliably and at low cost. it can. Further, even during normal operation, if two units are operated simultaneously, exhaust can be performed with a larger air volume. As for the positional relationship before and after the main blower 42 and the spare blower 43, any of them may be arranged in front.

  In addition, the problem in the serial arrangement as shown in FIG. 3 is that the life of the preliminary blower 43 is shortened because the combustion gas passes through the spare blower 43 at all times during the operation of the garbage carbonization apparatus 1. When the blowers 42 and 43 are operated independently, the blower in the stopped state causes a pressure loss with respect to the blower in the operating state. The shortening of the life of the preliminary blower 43 occurs due to deterioration of the bearing portion lubricating oil due to exhaust gas that passes during non-operation, wear of brushes or the like due to rotation of the blades of the preliminary blower 43 under the wind pressure of the main blower 42, and the like.

  Moreover, when it is set as parallel arrangement | positioning as shown in FIG. 4, two air blowers do not become a mutual pressure loss. The exhaust capacity can also be improved in the case of simultaneous operation of two units. Further, it is possible to extend the life by avoiding the influence of the passing exhaust gas in the case of the serial arrangement. In addition, in the case of parallel arrangement, for example, when two fans are individually operated individually, the exhaust gas flows backward inside the stopped blower, and the exhaust gas is not exhausted but is circulated through the two fans and exhausted. There is a problem that efficiency decreases.

  FIG. 5 shows an exhaust system that avoids the problem of exhaust efficiency reduction due to the exhaust gas circulation described above. That is, this exhaust system includes a three-way switching valve 46 at a position where the pipe 63 branches to each blower, and the switching valve 46 is switched according to the operation of each blower 42, 43. Although the problem can be solved by arranging such a switching valve 46, the cost of the switching valve 46 itself and the cost for ensuring the reliability of the operation of the switching valve 46 are added to the apparatus cost. There is.

  Next, the exhaust part 4 in the garbage carbonization apparatus 1 shown in FIG. 1 will be described with reference to FIGS. The exhaust part 4 shown in these drawings is an improvement of the exhaust part 4 described with reference to FIGS. As shown in FIG. 6, the exhaust unit 4 includes a main blower 42 and a preliminary blower 43 arranged in parallel, and an ejector 44 provided at a junction in the downstream portion of each of the blowers 42 and 43. The ejector 44 prevents backflow, and can independently operate each of the fans 42 and 43 with high exhaust efficiency without using the three-way switching valve 46 shown in FIG. And As will be described later, the ejector 44 is integrated with the silencer 44 shown in FIG.

  7A and 7B show the structure and operating principle of the ejector 44. FIG. As shown in FIG. 7A, the ejector 44 connects the downstream pipe 64 of the main blower 42 to the exhaust pipe 45 through the enlarged diameter portion, and connects the downstream pipe 65 of the preliminary blower 43 to the enlarged diameter portion. It has a structure that is inserted into the inside and terminated with an opening. In general, a so-called ejector is used as a fluid pump. When the fluid is, for example, a gas, a part of the gas pipe for suction is expanded, and a structure in which a driving gas pipe is terminated and opened inside thereof. And a negative pressure is generated by the fluid blown out from the driving gas pipe to form a fluid flow in the suction gas pipe. The ejector 44 used here has no main purpose in such a pump function, and utilizes a backflow prevention function resulting from the structure of the so-called ejector. Therefore, the drive gas pipe of the ejector 44 is connected to the downstream pipe 65 of the auxiliary blower 43, and the suction gas pipe is provided so as to surround the drive gas pipe substantially coaxially, and is connected to the downstream pipe 64 of the main blower 42. It is connected.

  In the ejector 44 having the above-described structure, when either one of the fans 42 and 43 is operated independently, the exhaust pressure of the operating fan is used as a driving source to set the discharge portion of the non-operating fan to a negative pressure. Therefore, the backflow can be greatly reduced as compared with the exhaust system shown in FIG. FIG. 7A schematically shows the gas flow in the ejector 44 when the main blower 42 is operated and the preliminary blower 43 is stopped. The gas G3 from the dilution cooling chamber 41 is discharged to the exhaust cylinder 45 as indicated by the arrow a, and the flow indicated by the arrow b flowing backward to the pipe 65 is suppressed to a slight extent. FIG. 7B schematically shows the gas flow in the ejector 44 when the main blower 42 is stopped and the spare blower 43 is in operation. The gas G3 from the dilution cooling chamber 41 is discharged to the exhaust cylinder 45 as indicated by an arrow c, and the flow indicated by the arrow d flowing backward to the pipe 64 is suppressed to a slight extent. In addition, the air blowing capacity during simultaneous operation of the two units is not impaired by the ejector 44.

  Here, the silencer function of the ejector 44 will be described. Noise generated with the operation of the blowers 42 and 43 is usually reduced by a silencer (silencer). Usually, the silencer has a structure in which a part of the exhaust pipe is enlarged in diameter and a sound absorbing material is lined inside thereof, and the sound is silenced by absorbing the sound in the sound absorbing material. As shown in FIGS. 7A and 7B, the sound absorber 44a is lined inside the enlarged diameter portion of the ejector 44, whereby the ejector 44 and the silencer can be integrated. The muffler effect of the ejector 44 is mainly the effect of reducing the operation noise of the main blower 42. However, considering that the operation frequency of the auxiliary blower 43 is low, there is no practical problem. . From this, in the structure of the ejector 44, the main blower 42 is connected to the suction side, and the auxiliary blower 43 is connected to the drive side.

  FIGS. 8 and 9 show specific examples of the exhaust section 4 provided with the above-described ejector 44 with a silencer function. The exhaust unit 4 includes a rectangular dilution cooling chamber 41, a similarly rectangular ejector 44 (silencer 44), pipes 63, 64, 65 connecting them, a large main blower 42, and a small spare blower 43 in a substantially rectangular area. It is configured.

  Next, the verification experiment result of the effect of the ejector 44 with the silencer function described above will be described. FIG. 10 shows a block configuration of the garbage carbonization apparatus used in the verification experiment. The main fan 42 used was AC200V-200W, and the spare fan 43 used was DC12V-40W. 6 is provided with shut-off valves 42a and 42b for verification experiments (hereinafter referred to as D1 and D2) upstream of the main fan 42 and the spare fan 43 (hereinafter referred to as B1 and B2), respectively. Yes. In the verification experiment, the flow rate of the gas G4 downstream of the ejector 44 was measured under the combination of operation and stop of each blower and opening and closing of each shut-off valve. During the verification experiment, the carbonization section 2 and the combustion section 3 are not heated, and therefore no dry distillation gas G2 is generated. Therefore, the air A1 flowing into the combustion unit 3 is the gas G2, and the total amount of the air A2 and the gas G2 flowing into the dilution cooling chamber 41 is the gas G3. The measurement results are shown in Table 1.

  As shown in Table 1, the valve D2 is closed to forcibly prevent backflow, the air flow when the main blower B1 is operated independently (condition No2) is 3,743 L / min, and the valve D2 is opened. The air flow when the main blower B1 is operated independently (condition No1) is 3,460 L / min in the backflow enabled state. When the backflow is stopped and the backflow is allowed, the air flow reduction (backflow rate) is 7.6%.

  In addition, the valve D1 is closed to forcibly prevent backflow, and the air volume when the preliminary blower B2 is operated independently (condition No. 4) is 3,743 L / min, and the valve D1 is opened to enable backflow. The amount of air when the preliminary blower B2 is operated independently (condition No. 3) is 3,065 L / min. When the backflow is stopped and the backflow is allowed, the air flow reduction (backflow rate) is 3.1%.

  As described above, the reason why the backflow rate is suppressed to a low value of 7.6% or 3.1% is due to the effect of the backflow prevention function of the ejector 44. Thereby, it was confirmed that the preliminary blower 43 can be arranged without using the three-way switching valve 46 as shown in FIG. In addition, when the two fans are operated simultaneously (condition No. 5), the air volume is 4,150 L / min, and the auxiliary fan 43 is operated as necessary during normal operation in which the main fan 42 is operable. As a result, the effectiveness of exhausting a large amount of air was confirmed.

  The present invention is not limited to the above-described configuration, and various modifications can be made. For example, instead of the carbonizing heater 21 or the combustion heater 31, fuel gas or fuel oil may be used as the heating means. The structure of the ejector 44 (silencer 44) is not limited to a quadrangle, and may be a cylindrical shape, and the pipes 64 and 65 connected to the ejector 44 may not be parallel to each other.
