도 1은 본 발명의 전체적인 시스템을 도시한 것으로, 이를 참조하여 상세히 설명하면,Figure 1 illustrates the overall system of the present invention, described in detail with reference to this,
축산폐수를 모아지는 축산폐수 저장탱크(1)에서 이동된 축산폐수를 고액분리장치(2)에 의하여 원심분리작용으로 고형분과 뇨로 분리하여 분리된 고형분을 콘베이어 등의 이송장치(4)에 의하여 이송 저장하는 안정화 저장창고(5)에 저장되는데 고형분에 악취와 파리, 모기 등의 해충을 방제하기 위하여 분말의 소석회를 소량투입으로 안정화 퇴비처리를 하여 토질개량제와 유기질비료로 사용될 수 있도록 한다.The livestock wastewater moved from the livestock wastewater storage tank (1) where the livestock wastewater is collected is separated into solids and urine by centrifugal separation by the solid-liquid separator (2), and the separated solids are transferred by a conveyer (4) such as a conveyor. It is stored in the stabilized storage warehouse (5) to be stored in order to control the pests such as odors, flies, mosquitoes, etc. in the solid content by stabilizing composting with a small amount of powdered lime to be used as a soil improver and organic fertilizer.
상기 분리과정에서 액상분은 뇨가 95%이상을 함유하고 있는 상태로 1차 보관하는 뇨저장탱크(3)에 보관되어진다.In the separation process, the liquid component is stored in the urine storage tank 3 for primary storage in a state containing 95% or more of urine.
뇨저장탱크(3)에 보관된 뇨를 슬러지 이송펌프(6)에 의하여 이송라인(7)을 따라 이송되어 1차 예열시키도록 히타 등의 예열장치(9)를 설치한 홉퍼형상을 이루는 자동연속투입 저장장치(8)에 공급하고, 상기 뇨저장탱크(3)에 수위감지장치를 설치하여 수위에 따라 자동으로 슬러지 이송펌프(6)를 작동시키어 적정량이 공급이 이루어지도록 한다. 또한 저장장치(8)에 공급된 뇨는 1차적으로 예열장치(9)에 의하여 40℃∼50℃로 가열시킨 상태로 틴필름(THIN FILM)저온진공건조장치(10)로 투입이 된다.Automatic continuity forming a hopper shape in which a preheating device 9 such as a heater is installed so that urine stored in the urine storage tank 3 is transferred along the transfer line 7 by the sludge transfer pump 6 and preheated first. It is supplied to the input storage device (8), the water level detection device is installed in the urine storage tank (3) to automatically operate the sludge transfer pump (6) according to the water level so that the appropriate amount is supplied. In addition, the urine supplied to the storage device 8 is first introduced into the THIN FILM low temperature vacuum drying device 10 while being heated to 40 ° C. to 50 ° C. by the preheating device 9.
틴필름(THIN FILM)저온진공건조장치(10)에 투입된 뇨를 기계적인 구동장치에 의하여 이중자켓트(11)로된 내벽에 액막으로 얇게 펼쳐주는 작용과 함께 이를 열매체가열장치(17)에 의하여 내벽을 가열시키어 진공작용으로 인한 감압상태에서 1차 가열된 뇨를 단시간에 비등시키도록 한다.The thin film of urine introduced into the THIN FILM low temperature vacuum drying apparatus 10 is mechanically spread on the inner wall of the double jacket 11 with a liquid film, and the heat medium is heated by the heating medium 17. The inner wall is heated to boil the primary heated urine in a short time under reduced pressure due to the vacuum action.
그리고 상기 과정에 의하여 비등된 증기는 응축시키어 응축수로 변환, 배출하는 응축장치(20)로 보내져 처리하게 된다.In addition, the steam boiled by the above process is condensed, converted into condensed water, and sent to a condenser 20 for discharge.
상기 틴필름(THIN FILM)저온진공건조장치(10)는 원통형상의 자케트(11) 상부에 설치한 모터(12)에 의해 구동되게 축설한 로타(13)의 회전에 의하여 로타(13)의 둘레에 교호적으로 설치한 추진안내날개(14)가 유입되는 뇨를 이중자케트(11)의 내벽에 액막으로 얇게 펼쳐주게 되고 동시에 이중자케트(11)내에 열매체 오일저장탱크와 펌프 및 보일러를 포함하는 열매체 가열장치(17)에 의하여 순환된 가열열매체의 가열로 인하여 뇨가 최소의 시간에 진공에 의한 감압상태에서 저온도로 비등되도록 하며, 비등으로 발생되는 소량의 분말은 하단부에 설치된 홉퍼(15)로 모아지면서 배출구(16)를 통해 외부로 배출시키도록 한 것이다.The thin film (THIN FILM) low temperature vacuum drying apparatus 10 is the circumference of the rotor 13 by the rotation of the rotor 13 arranged to be driven by the motor 12 installed on the cylindrical jacket 11 Urine flows into the inner wall of the double jacket (11) to thinly spread the urine flowing in the guide guide blades 14 installed alternately in the double jacket 11 at the same time includes a heat medium oil storage tank, a pump and a boiler. Due to the heating of the heating heat medium circulated by the heating medium heating device 17, urine is boiled at a low temperature in a reduced pressure state by vacuum at a minimum time, and a small amount of powder generated by boiling is provided at the bottom of the hopper 15 As it is collected to be discharged to the outside through the outlet (16).
상기 응축장치(20)는 틴필름(THIN FILM)저온진공건조장치(10)에 의해 비등된 증기를 응축기(21)에서 받아 냉각탑(23)에 의하여 냉각된 냉각수가 순환펌프(22)의 공급으로 증기를 응축시키어 응축된 응축수는 탱크(24)에 모여 배수라인을 통해 배출되어 청소용등으로 재활용할 수 있다.The condenser 20 receives the steam boiled by the THIN FILM low temperature vacuum drying apparatus 10 from the condenser 21 and the cooling water cooled by the cooling tower 23 is supplied to the circulation pump 22. The condensed water condensed by condensing the steam is collected in the tank 24 and discharged through the drain line can be recycled for cleaning.
한편, 응축수탱크(24)를 통해 연결되는 진공펌프(25)에 의하여 전시스템에 진공을 유지하며 흐름은 강제, 배기가 원활히 유지되도록 하기 위하여 진공도는 600-650mmHg를 유지시키는 것이 바람직하다.On the other hand, it is preferable to maintain the vacuum degree 600-650mmHg in order to maintain the vacuum in the entire system by the vacuum pump 25 connected through the condensate tank 24, the flow is forced, exhaust is smoothly maintained.
그리고 틴필름(THIN FILM)저온진공건조장치(10)에 스케일 청소를 할 경우에는 뇨를 개폐하는 밸브를 차단하고 3-5분정도 시스템을 가동시키면 치적된 스케일등은 분말화되어 하방의 홉퍼(15)로 떨어져 외부로 배출시킬 수 있어 스케일방지와 청소작업이 이루어진다.In the case of the scale cleaning on the THIN FILM low temperature vacuum drying apparatus 10, the valves for opening and closing the urine are shut off and the system is operated for about 3 to 5 minutes. 15) can be discharged to the outside to prevent scaling and cleaning.
이상과 같이 본 발명은 처리가 난이한 축산폐수 및 분뇨가 분리과정을 거쳐 최소의 열량으로 최대용량을 처리하도록 뇨를 내벽에 얇게 펼쳐서 최소의 체류시간으로 진공상태에서 연속적으로 비등, 건조시킨 다음 응축수인 증류수로 처리하는 과정에 의해 근본적으로 폐수를 무방류 처리하므로서 환경오염에 상당한 기여를 할수 있는 것이며, 또한 농가에서 사용할 때에 따르는 유지, 관리비가 극히 저렴한 경제성을 갖는 효과가 있다.As described above, the present invention spreads the urine thinly on the inner wall to treat the maximum capacity with the minimum amount of heat through the separation process of livestock wastewater and manure, which is difficult to process, and then continuously boils and vacuums the vacuum at the minimum residence time and then condensate. By treating with distilled water, it is possible to make a substantial contribution to environmental pollution by essentially freeing wastewater, and there is an effect of having economical maintenance and management costs that are extremely low when used in farms.
