Description

음식쓰레기분말용 연소장치{burner for food waste powder}FIELD OF THE INVENTION The present invention relates to a burner for food waste powder,

본 발명은 음식쓰레기분말용 연소장치에 관한 것이다.The present invention relates to a combustion device for food waste powder.

음식쓰레기를 처리하는 방안에는 소각하는 제1방안, 퇴비화하는 제2방안 및 매립하는 제3방안이 있다.Methods for treating food waste include a first method of incineration, a second method of composting, and a third method of landfilling.

퇴비화하는 제2방안은 한국음식쓰레기 특성상 염분이 많아 부적절하고, 그리고 매립하는 제3방안은 침출수가 많이 발생되어 토양과 주변의 하천을 오염시킬 수 있고 매립택지를 마련하기가 어렵다고 하는 문제점이 있다.The second method of composting is the inadequate method because of the high salinity due to the nature of Korean food waste, and the third method of landfilling is that there is a lot of leachate, which can contaminate the soil and surrounding rivers, and it is difficult to prepare landfill.

소각하는 제1방안은 등록실용20-0199645호에 개시된 바와 같이, 음식쓰레기를 건조하여 분말화된 음식쓰레기분말을 공기와 함께 소각로에 투입하여 연소시켜 소각시키고 있지만, 소각로에 구비된 버너의 화염에 의해 음식쓰레기분말을 소각하는 것이어서, 버너의 화염을 제공하기 위한 별도의 기상, 액상 또는 고상 연료가 필요된다고 하는 문제점이 있다.In the first method of incineration, as described in Korean Utility Model No. 20-0199645, the food waste is dried and the powdered food waste powder is injected into the incinerator together with air to be burned and burned, but the flame of the burner provided in the incinerator is burned. By incinerating the food waste powder, there is a problem that a separate gaseous, liquid or solid fuel is required to provide a burner flame.

또한, 상기 개시된 제1방안은 음식쓰레기분말을 송풍기의 날개와 접촉시켜 소각로 내로 공급하기 때문에, 송풍기의 날개가 용이하게 부식 및 손상될 수 있다고 하는 문제점을 가진다.In addition, the first method disclosed above has a problem that the blades of the blower can be easily corroded and damaged because the food waste powder is brought into contact with the blades of the blower and supplied into the incinerator.

본 발명은 상기된 문제점을 해결하는 것에 과제를 가진다.The present invention has a problem in solving the above problems.

본 발명은 통상의 난방 또는 스팀제조 보일러나 화력 발전기에 구비된 연소장치의 연소실에 공기공급원에 접속된 공기공급관을 접속시키고, 상기 공기공급관의 도중에 유량조절밸브를 개재시키고, 기화되어 이송되는 액화천연가스공급관의 도중에 이젝터를 개재시켜 상기 이젝터에 음식쓰레기분말공급관을 접속시켜 음식쓰레기분말을 액화천연가스공급관에 공급하여 상기 액화천연가스공급의 하류단에 접속된 노즐을 통하여 연소실 내의 점화원에 기화된 액화천연가스와 음식쓰레기분말을 함께 분사시켜 화염을 만들어서 연소실에 구비된 물탱크를 가열하여 음식쓰레기분말을 연료로서 사용하고, 음식쓰레기분말공급관의 상류단에 로터리밸브를 개재하여 음식쓰레기분말이 저정된 호퍼의 음식쓰레기분말배출관을 접촉시켜, 액화천연가스가 상기 음식쓰레기공급관쪽으로 역류하는 것을 방지함으로써, 상기 과제를 해결할 수 있다. The present invention connects an air supply pipe connected to an air supply source to a combustion chamber of a combustion apparatus provided in a conventional heating or steam-producing boiler or a thermal power generator, interposes a flow control valve in the middle of the air supply pipe, and vaporizes and transports the liquefied natural gas. A food waste powder supply pipe is connected to the ejector through an ejector in the middle of the gas supply pipe, and the food waste powder is supplied to the liquefied natural gas supply pipe, and liquefied to the ignition source in the combustion chamber through a nozzle connected to the downstream end of the liquefied natural gas supply. Natural gas and food waste powder are sprayed together to create a flame to heat the water tank provided in the combustion chamber to use the food waste powder as fuel, and the food waste powder is stored through a rotary valve upstream of the food waste powder supply pipe. The liquefied natural gas is damaged by contacting the food waste powder discharge pipe of the hopper. By preventing the reverse flow toward the food waste supply pipe, it is possible to solve the above problems.

본 발명은 상기와 같은 과제해결수단에 의해 음식쓰레기분말이 연소실에 연속적으로 공급되어 액화천연가스와 함께 연소되어서 연료원이 되게 하여, 난방 또는 스팀제조 보일러나 화력 발전기의 가동에 필요되는 액화천연가스의 양을 절감하여 난방 또는 스팀제조 보일러나 화력 발전기의 운용비용을 절감함과 동시에, 음식쓰레기의 처리를 위한 매립방안 또는 퇴비화 방안에서 발생되는 환경파괴 문제를 극복할 수 있다. According to the present invention, the food waste powder is continuously supplied to the combustion chamber to be burned together with the liquefied natural gas to be a fuel source by the above-described problem solving means, and thus, the liquefied natural gas required for the operation of a heating or steam producing boiler or a thermal power generator. By reducing the amount of fuel, the operating cost of heating or steam-fired boilers and thermal power generators can be reduced, and the environmental problems caused by landfill or composting methods for the disposal of food waste can be overcome.

상기 음식쓰레기분말저장부(40)는 전체적으로 호퍼형상으로 되어 있고, 상기 음식쓰레기분말투입관(50)의 상류단은 상기 음식쓰레기분말저장부(40)의 하부를 관통하여 상기 음식쓰레기분말저장부(40)의 상단 또는 중간에 배치되어 있다.The food waste powder storage unit 40 has a hopper shape as a whole, and the upstream end of the food waste powder input pipe 50 penetrates through the lower portion of the food waste powder storage unit 40 to store the food waste powder storage unit. It is arrange | positioned at the upper end or the middle of 40.

또한, 상기 음식쓰레기분말저장부(40)에는 상기 음식쓰레기분말저장부(40) 내에 저장된 상기 음식쓰레기분말을 교반하여 상기 음식쓰레기분말저장부(40) 내에서 비산하게 하는 교반기(41)가 구비되어 있다.The food waste powder storage unit 40 may further include a stirrer 41 for stirring the food waste powder stored in the food waste powder storage unit 40 and scattering the food waste powder in the food waste powder storage unit 40 .

상기 음식쓰레기분말투입관(50)의 상류단은 상기 음식쓰레기분말저장부(40)의 정중앙에 배치되어 있고 상기 음식쓰레기분말공급관(70)의 하류단은 상기 음식쓰레기분말투입관(50)의 상류단에 대하여 수평방향으로 일정 거리 만큼 편위되어 있다.The upstream end of the food waste powder input pipe 50 is disposed at the center of the food waste powder storage unit 40 and the downstream end of the food waste powder supply pipe 70 is the food waste powder input pipe 50. It is shifted by a certain distance in the horizontal direction with respect to the upstream end.

또한, 상기 음식쓰레기분말투입관(50)의 상류단의 개구(50a)는 도 1에 도시된 바와 같이 상기 음식쓰레기분말공급관(70)의 하류단 방향으로 향하지 않게 상기 음식쓰레기분말공급관(70)의 하류단에 대하여 반대 방향으로 개구되어 있어서, 상기 음식쓰레기분말공급관(70)의 하류단에서 공급되는 상기 음식쓰레기분말이 바로 상기 음식쓰레기분말투입관(50)의 상류단의 개구(50a) 내로 유입되는 것이 방지되게 되어 있다.In addition, the opening 50a of the upstream end of the food waste powder input pipe 50 is not directed toward the downstream end of the food waste powder supply pipe 70 as shown in FIG. 1. The food waste powder supplied from the downstream end of the food waste powder supply pipe 70 directly into the opening 50a of the upstream end of the food waste powder input pipe 50. Inflow is prevented.

또한, 상기 음식쓰레기분말투입관(50)의 도중에는 밸브판의 개도를 달리하여 상기 이젝터(30)에 투입되는 상기 음식쓰레기분말의 양을 조절할 수 있는 분말유량조절밸브(51)가 개재되어 있다.In addition, in the middle of the food waste powder injection pipe 50, there is a powder flow rate control valve 51 that can adjust the amount of the food waste powder introduced into the ejector 30 by varying the opening degree of the valve plate.

상기와 같이 구성된 음식쓰레기분말용 연소장치(100)는 다음과 같이 작동될 수 있다. The combustion apparatus 100 for food waste powder configured as described above may be operated as follows.

먼저, 분말유량조절밸브(51)를 닫은 상태에서 상기 액화천연가스공급관(20)의 상류단에 개재된 도시되지 않은 온오프밸브를 개방하면, 상기 액화천연가스공급원(21)의 액화천연가스가 액화천연가스공급관(20)에 유입되면서 기화되어 상기 이젝터(30)를 경유하여 노즐(17)을 통하여 점화원(16)에 분사되어 점화원(16)의 불꽃에 의해 화염이 되어 상기 탱크(15)를 가열하게 되며, 연소된 연소가스는 배기관(14)을 통하여 대기로 방출되게 된다. 이 때에 공기유량조절밸브(13)를 개방하여 연소실(10)에 일정 유량의 공기를 주입하여 상기 연소실에 분사된 상기 액화천연가스가 완전연소되게 한다. First, when the on-off valve (not shown) interposed at an upstream end of the liquefied natural gas supply pipe 20 in a state where the powder flow control valve 51 is closed, the liquefied natural gas of the liquefied natural gas supply source 21 is The gas is introduced into the liquefied natural gas supply pipe 20, and is vaporized and injected into the ignition source 16 through the nozzle 17 through the ejector 30 to be flamed by the flame of the ignition source 16, thereby to open the tank 15. The heated combustion gas is discharged to the atmosphere through the exhaust pipe 14. At this time, the air flow control valve 13 is opened to inject air of a predetermined flow rate into the combustion chamber 10 so that the liquefied natural gas injected into the combustion chamber is completely burned.

이 상태에서, 로터리밸브(80)를 가동하면서, 분말유량조절밸브(51)를 개방하면, 상기 이젝터(30)의 입구(31)가 음압상태인 관계로, 상기 음식쓰레기분말저장부(40)에 저장된 음식쓰레기분말이 상기 음식쓰레기분말공급관(50)의 상류단 내로 연속적으로 유입되어 상기 이젝터(30)에서 상기 액화천연가스와 혼합되어 노즐(17)을 통하여 점화원(16)에 연속적으로 분사되게 되어, 연소실(10) 내에서 상기 액화천연가스와 함께 화염이 되어서 탱크(15)를 가열하기 위한 연료로서 작용하게 되며, 연소된 연소가스가 배기관(14)을 통하여 대기로 방출되게 된다. 이 때에, 공기유량조절밸브(13)의 개도를 조절하여 상기 액화천연가스와 함께 연소실에 분사된 음식쓰레기분말이 완전연소될 수 있는 유량의 공기를 연소실(10) 내에 주입하게 된다.In this state, when the powder flow rate control valve 51 is opened while the rotary valve 80 is operated, the food waste powder storage unit 40 is connected to the inlet 31 of the ejector 30 in a negative pressure state. Food waste powder stored in the continuous inflow into the upstream end of the food waste powder supply pipe 50 is mixed with the liquefied natural gas in the ejector 30 to be continuously sprayed to the ignition source 16 through the nozzle 17 Thus, it becomes a flame together with the liquefied natural gas in the combustion chamber 10 to act as a fuel for heating the tank 15, and the combusted combustion gas is discharged to the atmosphere through the exhaust pipe 14. At this time, the opening of the air flow rate control valve 13 is adjusted to inject air into the combustion chamber 10 at a flow rate at which the food waste powder injected into the combustion chamber together with the liquefied natural gas can be completely burned.

상기 로터리밸브(80)는 음식쓰레기분말공급원(60)의 음식쓰레기분말을 상기 로터리밸브(80)의 밸브판의 회전수에 따라 공급량을 달리하여 음식쓰레기분말저장부(40)에 공급하는 작용을 하며, 상기 음식쓰레기분말저장부(40)에 음압이 형성되어도 상기 음식쓰레기분말공급원(60)에 음압이 미치지 않게 하는 밸브이다.The rotary valve 80 serves to supply the food waste powder of the food waste powder supply source 60 to the food waste powder storage unit 40 at different supply amounts according to the rotational speed of the valve plate of the rotary valve 80 And a negative pressure is not applied to the food waste powder supply source 60 even if negative pressure is formed in the food waste powder storage part 40. [

그 이유는 밸브판이 하우징에 기밀적으로 미끄럼접촉하고 있기 때문이며, 이에 대한 상세한 구성은 본 발명에 의해 출원되어 계류중인 특허출원 제10-2013-028146호에 개시되어 있다.This is because the valve plate slidably contacts the housing in an airtight manner, and a detailed configuration thereof is disclosed in the pending patent application No. 10-2013-028146 filed by the present invention.

또한, 상기 교반기(41)는 상기 분말유량조절밸브(51)가 개방상태에 있을 때, 가동되면, 상기 음식쓰레기분말저장부(40)에 저장된 음식쓰레기분말이 상기 음식쓰레기분말저장부(40)에 내에서 비산하게 되어 용이하게 상기 음식쓰레기분말투입관(50)의 상류단쪽으로 유도될 수 있다는 관점에서 바람직하다.In addition, the agitator 41 is operated when the powder flow rate control valve 51 is in an open state, the food waste powder stored in the food waste powder storage unit 40 is the food waste powder storage unit 40. It is preferable from the viewpoint of being scattered within the easiness can be easily guided toward the upstream end of the food waste injection pipe (50).

상기와 같이 구성된 음식쓰레기분말용 연소장치(100)는 음식쓰레기분말이 연소실에 연속적으로 공급되어 액화천연가스와 함께 연소되어서 연료원이 되게 하여, 난방 또는 스팀제조 보일러나 화력 발전기의 가동에 필요되는 액화천연가스의 양을 절감하여 난방 또는 스팀제조 보일러나 화력 발전기의 운용(에너지)비용을 절감함과 동시에, 음식쓰레기의 처리를 위한 매립방안 또는 퇴비화 방안에서 발생되는 환경파괴 문제를 극복할 수 있다. The combustor 100 for food waste powder configured as described above is fed to the combustion chamber with the food waste powder to be burned together with the liquefied natural gas to be a fuel source, which is required for the operation of a heating or steam manufacturing boiler or a thermal power generator. Reducing the amount of liquefied natural gas reduces the operating (energy) costs of heating or steam-producing boilers or thermal power generators, and overcomes environmental problems caused by landfill or composting methods for the disposal of food waste. .
