일반적으로, 가연성폐기물이나 폐기물 고형연료(RDF, Refuse Derived Fuel)속의 염소성분은 연소에 의해서 기체상의 염화수소가스로 바뀌고 연소가스 속에 포함되어 배출된다. 배출되는 연소가스를 흡수액속으로 통과시키면 염화수소는 흡수액에 포집되어 염소이온으로 잔류하게 되고 이 흡수액속의 염소이온 농도를 측정하면 폐기물속의 염소함량을 알 수 있다.In general, chlorine in flammable waste or waste solid fuel (RDF) is converted into gaseous hydrogen chloride gas by combustion and is contained in the combustion gas and discharged. When the discharged combustion gas passes through the absorbent liquid, hydrogen chloride is collected in the absorbent liquid and remains as chlorine ions. By measuring the concentration of chlorine ion in the absorbent liquid, the chlorine content in the waste can be known.

도 1에서 알 수 있는 바와 같이, 크게는 1차 열분해 반응관과 2차 연소실로 나누어지고 있으며, 1차 열분해반응관은 이동식 전기로(13)에 의하여 이동식 가열장치가 시료를 중심으로 왕복을 하면서 가열온도를 서서히 올려서 시료의 열분해가 일어나게 하고 2차 연소실은 고정식 전기로(16)에 의하여 충분한 공간을 마련하여 항상 900℃를 유지시켜서 1차 열분해 반응관에서 생성된 열분해가스를 완전연소시키는 방법을 사용하고 있다.As can be seen in Figure 1, it is largely divided into a primary pyrolysis reaction tube and a secondary combustion chamber, the primary pyrolysis reaction tube is a mobile heating device reciprocating around a sample by a mobile electric furnace (13) The pyrolysis of the sample occurs by gradually raising the heating temperature, and the secondary combustion chamber provides a sufficient space by the fixed electric furnace 16 to maintain 900 ° C at all times to completely burn the pyrolysis gas generated in the primary pyrolysis reaction tube.

In more detail, the configuration of the present invention, the flow meter 51 for adjusting the amount of combustion air, the air-tight connecting device 70 for connecting the pipe and the pipe 52, and the primary A primary pyrolysis section by the pyrolysis furnace 53, a thermocouple 54 for measuring the temperature of the primary pyrolysis section, a sample plate 55 made of a ceramic material for containing the sample into the tube 52, 2 A thermocouple 56 for measuring the temperature of the primary combustion chamber, a secondary combustion chamber portion by the secondary combustion chamber electric furnace 57, a combustion tube 58 which does not react with hydrogen chloride, the tube 52, The connection device 70 formed in the same hermetic structure, the absorbing liquid 60 made of ultrapure water to absorb the hydrogen chloride gas generated during the combustion of the sample, and the size of the bubble is made small so that the hydrogen chloride in the combustion flue gas is absorbed in the ultrapure water well. Glass filtration plate (61) for, and the impinge containing ultrapure water The primary pyrolysis chamber temperature for regulating the temperature of the bottom 62, the secondary combustion chamber temperature controller 63 for adjusting the temperature of the secondary combustion chamber electric furnace 57, and the primary pyrolysis furnace 53 A regulator 64, a vacuum pump 65 for intake of combustion air for combusting a sample, and an ultrapure water impinger 66 for cleaning air containing ultrapure water for the purpose of cleaning the combustion air and supplying clean air to the combustion tube. And an empty bottle 67 for preventing ultrapure water from entering the combustion tube, and a quartz which serves to achieve complete combustion by stably supplying pyrolysis gas, tar and unburned carbon generated in the primary pyrolysis chamber to the secondary combustion chamber. Or it relates to a flammable solid fuel made of a reduction tube 68 and the like made of a ceramic material and a complete combustion reactor for analyzing the amount of chlorine contained in the waste.
도 3은 본 발명에 따른 축소관을 나타낸 개략도로서, 축소관(68)을 연소관(58)중앙에 삽입하여 완전연소가 가능하도록 하고자 하는 것이다.3 is a schematic view showing a reduction tube according to the present invention, which is intended to enable complete combustion by inserting the reduction tube 68 in the center of the combustion tube 58.
1차 열분해전기로(53)에서 이루어지는 1차 열분해실에서 생성되는 열분해가스, 타르 및 미연탄소는 열분해온도에 따라서 생성량이 다르다.The amount of pyrolysis gas, tar and unburned carbon produced in the primary pyrolysis chamber formed in the primary pyrolysis furnace 53 varies depending on the pyrolysis temperature.
예를 들면 폴리에칠렌은 400∼500℃ 구간에서 급격히 열분해되고 염화비닐은 250∼300℃ 구간에서 열분해가 일어난다. 가연성폐기물이나 RDF는 다양한 종류의 물질과 불균일한 량으로 혼합되어 있으므로 열분해가스, 타르 및 미연탄소의 생성량을 일정하게 하기가 매우 어렵고 따라서 일정한 공기가 공급되는 2차연소실부 전기로(57)에서 이루어지는 2차연소실에서 완전연소가 어렵게 된다. For example, polyethylene is rapidly pyrolyzed in the 400 to 500 ℃ section and vinyl chloride is pyrolyzed in the 250 to 300 ℃ section. Since flammable waste or RDF is mixed in various amounts with different kinds of materials, it is very difficult to make constant the production of pyrolysis gas, tar and unburned carbon, and thus is made in the secondary combustion chamber electric furnace 57 where constant air is supplied. In the secondary combustion chamber, complete combustion becomes difficult.
축소관(68)은 1차 열분해 전기로(53)에 의한 1차 열분해실에서 생성된 물질의 량에 관계없이 어느 정도 일정하게 2차 연소실부 전기로(57)의 2차 연소실로 공급하는 역할을 한다. The reduction tube 68 supplies the secondary combustion chamber of the secondary combustion chamber electric furnace 57 to a certain degree irrespective of the amount of material generated in the primary pyrolysis chamber by the primary pyrolysis furnace 53. Do it.
1차 열분해실에서 열분해생성물질의 량이 갑자기 많아져서 유동의 하류로 유량이 많을 때 축소관(68)은 압축성 유체의 유동 저항으로 작용하여 균일한 유량이 되도록 작용한다. When the amount of pyrolysis products suddenly increases in the primary pyrolysis chamber and the flow rate is high downstream of the flow, the reduction tube 68 acts as a flow resistance of the compressive fluid to act as a uniform flow rate.
축소관(68)의 다른 실시예로서 유동저항으로 작용하는 장치는 축소관외에 여러 개의 구슬을 층으로 쌓아서 만든 것도 가능하며, 그 재질도 석영 혹은 세라믹으로 이루어 진 것을 특징으로 한다.As another embodiment of the reduction tube 68, the device acting as a flow resistance can be made by stacking a plurality of beads in addition to the reduction tube, it is characterized in that the material is also made of quartz or ceramic.
이상에서 설명한 바와 같이 본 발명에 따른 열분해실과 연소실 일체형의 전염소 분석용 완전연소관 장치는 구조가 매우 간단하므로 제작비가 저렴하고 수리가 용이한 장점이 있다.As described above, the complete combustion pipe apparatus for prechlorine analysis of the pyrolysis chamber and the combustion chamber integrated according to the present invention has a very simple structure, which is inexpensive to manufacture and easy to repair.
