Description

건조장치{Dryer}Drying Equipment {Dryer}

본 발명은 에너지 소비를 현저히 감소시킬 수 있는 건조기에 관한 것으로, 좀 더 구체적으로는 폐싸이클의 건조공정에서 루프 써모싸이폰 열교환기를 적용하되 루프 써모싸이폰 열교환기의 증발부를 냉각코일 전에 설치하여 예냉효과를 얻고, 루프 써모싸이폰 열교환기의 응축부를 냉각코일 후에 설치하여 저온의 포화상태 공기가 재가열되는 효과를 얻음으로써 에너지 소비를 현저하게 줄일 수 있도록 하는 건조기에 관한 것이다.The present invention relates to a dryer that can significantly reduce energy consumption, and more specifically, to apply a loop thermosyphon heat exchanger in a drying cycle of a waste cycle, but to pre-cool it by installing an evaporation unit of the roof thermophone heat exchanger before the cooling coil. The present invention relates to a dryer which achieves an effect and is installed after a cooling coil of a condensation part of a loop thermosyphone heat exchanger to reheat the low temperature saturated air, thereby significantly reducing energy consumption.

일반적으로 건조공정은 피건조물에 함유된 수분을 제거하는 공정으로, 주로 사용되는 열풍건조공정은 고온의 열풍을 불어넣어 습기를 제거하는 공정이므로 피건조물을 통과한 후의 열풍은 고온의 습공기로 변하게 된다.In general, the drying process is a process of removing moisture contained in the dry matter. The hot air drying process, which is mainly used, is a process of removing moisture by blowing high temperature hot air, so the hot air after passing through the dry matter is changed to high temperature wet air. .

특히, 열풍건조공정은 피건조물에 함유된 1㎏의 물을 수증기로 변화시키기 위해서는 이론적으로 600kcal의 열이 필요하게 되며, 전도전열, 복사전열 등을 이용하는 건조방식에 비하여 그 사용 분야가 광범위하다.In particular, the hot air drying process requires theoretically 600 kcal of heat in order to convert 1 kg of water contained in the dried material into water vapor, and its field of use is wider than the drying method using conduction heat, radiant heat and the like.

그러나, 열풍건조공정은 다른 건조방법에 비하여 고온습공기의 배기 방출량이 많고, 배기가 가지고 있는 열량도 크므로 에너지 소비가 큰 단점이 있기 때문에 고온의 습공기를 제습후 재순환하여 이용하거나 건조공정용 공기를 예열시키면 에너지 절약 효과를 향상시킬 수 있다.However, compared to other drying methods, the hot air drying process has a large amount of exhaust emissions of high temperature humid air and a large amount of heat that the exhaust has, so energy consumption is high. Preheating can improve energy savings.

건조공정에서 제습 후 재가열하는 시스템으로는 열펌프 시스템과 히트 파이프 기술을 이용하는 시스템이 있으며, 전자는 고온습공기를 열펌프의 증발부를 통과시켜 노점온도 이하로 냉각하여 제습한 후 응축부에서 재가열하는 방식이고, 후자는 대기를 이용하여 습공기의 온도를 노점온도 이하로 하여 제습하는 방식이다.Reheating after dehumidification in the drying process includes a heat pump system and a system using heat pipe technology. The former is a method in which the high temperature air is passed through the evaporation part of the heat pump to cool below the dew point temperature, dehumidified and then reheated in the condensation part. The latter is a method of dehumidifying the temperature of the humid air by using the atmosphere below the dew point temperature.

열펌프를 이용하는 방법은 도 1에 도시된 바와 같이 고온습공기를 작동유체(12)가 통과하는 냉각코일(11)이 설치된 증발부(10)를 통과시킨 다음, 가열매체(22)가 통과하는 재가열코일(21)이 설치된 응축부(20)를 통과시킴으로서 제습과 재가열을 행한 공기를 재사용하는 방법으로서 별도의 에너지원을 이용하여야 한다는 단점이 있으나 대기 온도보다도 낮은 건조공정에서도 사용 가능하다는 장점을 가지고 있으며, 히트파이프 제습방식은 구동원이 불필요한 대신에 열풍의 온도가 대기 온도보다 높고 대기온도에 의해 노점온도 이하로 떨어질 수 있는 조건에서만 사용 가능하다는 단점이 있다.In the method using the heat pump, as shown in FIG. 1, the high-temperature wet air passes through the evaporator 10 provided with the cooling coil 11 through which the working fluid 12 passes, and then the reheating of the heating medium 22 passes. As a method of reusing the dehumidified and reheated air by passing through the condensation unit 20 in which the coil 21 is installed, there is a disadvantage that a separate energy source must be used, but it can be used in a drying process lower than the ambient temperature. However, the heat pipe dehumidification method has a disadvantage in that it can be used only in a condition that a hot air temperature is higher than the air temperature and drops below the dew point temperature by the air temperature, instead of the driving source.

그러나, 대부분 건조공정의 열풍온도가 60℃ 이상인 경우가 많으므로 별도의 구동원이 불필요한 히트 파이프를 건조공정에 사용하는 것이 에너지 절약 측면에서 매우 유리하다.However, in most cases, the hot air temperature of the drying process is more than 60 ℃, it is very advantageous in terms of energy saving to use a heat pipe unnecessary for a separate driving source in the drying process.

한편, 히트 파이프는 열을 파이프를 통하여 전달하는 것으로 낮은 온도에서도 증발이 잘되는 작동 유체를 밀폐된 파이프 내에 주입하고 내부를 진공으로 하여 파이프의 한쪽에 고온의 열풍과 접촉시키면 작동 유체가 열풍으로부터 열을 흡수하여 증발하고 다른 한쪽에서 증기 상태의 작동 유체가 외부의 낮은 온도의 대기와 접촉하여 응축되는 시스템이다.On the other hand, the heat pipe transfers heat through the pipe, and injects a working fluid which evaporates well even at a low temperature into a sealed pipe and makes the inside of the pipe contact with a high temperature hot air on one side of the pipe, so that the working fluid can recover heat from the hot air. It is a system that absorbs, evaporates, and condenses a vapor working fluid in contact with an external low temperature atmosphere.

즉, 도 2에 도시된 바와 같이 단열부(30)에 의하여 증발부(10)와 응축부(20)의 외부가 구획되고, 밀봉된 용기(1) 내에 작동 유체(12)가 주입된 히트 파이프는 외부 열원에 의해 증발부(10)에서 작동 유체가 증발하고 응축부(20)와의 압력차가 발생해서 증발부(10)로부터 응축부(20)로 증기가 이동하며, 증기는 응축부(20)에서 증발잠열을 히트파이프 주위에 전달하고 응축되고, 응축된 액체는 다공성 윅(13)에 의해 증발부(10)로 이송된다.That is, as shown in FIG. 2, the heat pipe in which the outside of the evaporator 10 and the condenser 20 is partitioned by the heat insulating part 30, and the working fluid 12 is injected into the sealed container 1. The working fluid is evaporated from the evaporator 10 by an external heat source and a pressure difference occurs with the condenser 20 so that steam moves from the evaporator 10 to the condenser 20, and the steam is condensed 20. At latent heat transfer to the heat pipe around the condensation and condensation, the condensed liquid is transferred to the evaporator 10 by the porous wick (13).

그러나, 히트 파이프는 내부에 다공성 윅(13)이 반드시 필요하며, 열저항이 높아 성능이 만족스럽지 못한 단점이 있다.However, the heat pipe must have a porous wick 13 therein, and has a disadvantage in that its performance is not satisfactory due to high thermal resistance.

따라서, 본 발명의 목적은 구조가 간단하면서도 효율이 우수하여 에너지 소비를 현저히 감소시킬 수 있는 건조기를 제공하는 데 있다.Accordingly, it is an object of the present invention to provide a dryer which is simple in structure and excellent in efficiency and can significantly reduce energy consumption.

상술한 목적 뿐만 아니라 용이하게 표출되는 다른 목적을 달성하기 위하여 본 발명에서는 폐싸이클의 건조공정에서 루프 써모싸이폰 열교환기를 적용하되 루프 써모싸이폰 열교환기의 증발부를 냉각코일 전에 설치하여 예냉효과를 얻고, 루프 써모싸이폰 열교환기의 응축부를 냉각코일 후에 설치하여 저온의 포화상태 공기가 재가열되는 효과를 얻음으로써 에너지 소비를 현저하게 줄일 수 있도록 하였다.In order to achieve the above object as well as other objects that can be easily expressed, the present invention applies a loop thermosyphon heat exchanger in the drying cycle of the waste cycle, but installs the evaporation unit of the roof thermophone heat exchanger before the cooling coil to obtain a precooling effect. In addition, the condensation part of the loop thermosyphone heat exchanger was installed after the cooling coil to reduce the energy consumption by reheating the low temperature saturated air.

본 발명에 따른 건조기는 관형 용기(1)를 "U"자형으로 절곡하여 절곡부(3)를 형성하고, 절곡부(3)를 기준으로 두 부분의 관형 용기(1)가 상,하로 위치되도록 하고, 하부에 위치하는 관형 용기(1)로 고온습공기를 유입시켜 상부에 위치하는 관형 용기(1)로 유출시키며, 절곡부(3)를 기준으로 하는 두 부분의 관형 용기(1) 사이에 단열부(30)를 형성시키고, 하부의 관형 용기(1)에 작동유체(12)가 통과하는 냉각코일(11)을 설치하며, 하부의 관형 용기(1) 유입부에 써모싸이폰 열교환기의 증발부(10')가 위치하고 관형 용기(1) 유출부에 써모싸이폰 열교환기의 응축부(20')가 위치하도록 써모싸이폰 열교환기를 설치한 것으로 특징지워진다.The dryer according to the present invention bends the tubular container 1 into a “U” shape to form a bent portion 3, and the tubular vessel 1 of two parts is positioned up and down based on the bent portion 3. In addition, the hot and humid air flows into the tubular vessel (1) located in the lower portion and flows out into the tubular vessel (1) located in the upper portion, and is insulated between the tubular vessel (1) of two parts based on the bent portion (3) The unit 30 is formed, and the cooling coil 11 through which the working fluid 12 passes is installed in the lower tubular vessel 1, and the evaporation of the thermosyphon heat exchanger in the lower tubular vessel 1 inlet. It is characterized by the installation of a thermosyphon heat exchanger such that the section 10 'is located and the condensation section 20' of the thermosyphon heat exchanger is located at the outlet of the tubular vessel 1.

또한, 본 발명의 건조기는 써모싸이폰 열교환기로서 단일관형 또는 루프형이 사용되는 것을 특징으로 한다.In addition, the dryer of the present invention is characterized in that a single tube type or a loop type is used as the thermosyphon heat exchanger.

본 발명에서는 써모싸이폰 열교환기를 적용하기 위하여 관형 용기(1)를 "U"자형으로 절곡하여 절곡부(3)를 형성하고, 절곡부(3)를 기준으로 두 부분의 관형 용기(1)가 상,하로 위치되도록 한다. 즉, 써모싸이폰 열교환기는 반드시 증발부(10')가 응축부(20') 보다 하부에 위치시켜야 하기 때문에 관형 용기(1)를 절곡하여 사용한다. 그러나, 관형 용기(1)를 절곡하는 대신에 2개의 관을 "U"자관을 이용하여 고정 연결시켜 사용할 수도 있다.In the present invention, in order to apply a thermosyphon heat exchanger, the tubular vessel 1 is bent into a “U” shape to form a bent portion 3, and the tubular vessel 1 of two parts is formed based on the bent portion 3. Position it up and down. That is, the thermosyphon heat exchanger is used by bending the tubular container 1 because the evaporator 10 'must be located below the condenser 20'. However, instead of bending the tubular container 1, two tubes may be fixedly connected using the "U" magnetic tube.

또한, 써모싸이폰 열교환기의 증발부(10')가 하부에 위치하고 써모싸이폰 열교환기의 응축부(20')가 상부에 위치되도록 하고, 관형 용기(1)와 연결 구성되도록 하기 위하여 절곡부(3)를 기준으로 두 부분의 관형 용기(1)가 상,하로 위치되도록한다.In addition, the bent portion so that the evaporation portion 10 'of the thermosyphon heat exchanger is located at the lower portion and the condensation portion 20' of the thermosyphone heat exchanger is positioned at the upper portion and connected to the tubular vessel 1. Based on (3), the tubular container 1 of two parts is positioned up and down.

상기와 같이 "U"자형으로 절곡하여 절곡부(3)를 형성하고, 절곡부(3)를 기준으로 두 부분의 관형 용기(1)가 상,하로 위치되도록 한 관형 용기(1)와 써모싸이폰 열교환기를 연결 구성한다.As described above, the bent portion 3 is bent to form a “U” shape, and the tubular vessel 1 and the thermosy having two portions of the tubular vessel 1 positioned up and down based on the bent portion 3 are formed. Configure the phone heat exchanger connection.

즉, 하부의 관형 용기(1) 유입부에 써모싸이폰 열교환기의 증발부(10')가 위치하고 관형 용기(1) 유출부에 써모싸이폰 열교환기의 응축부(20')가 위치하도록 써모싸이폰 열교환기를 설치함으로써 써모싸이폰 열교환기의 증발부(10')가 하부에 위치하고 써모싸이폰 열교환기의 응축부(20')가 상부에 위치되도록 한다.In other words, the evaporator 10 'of the thermophone heat exchanger is located at the inlet of the tubular vessel 1 at the lower part, and the condensation unit 20' of the thermophone heat exchanger is located at the outlet of the tubular vessel 1. By installing the cyphon heat exchanger, the evaporator 10 'of the thermosyphon heat exchanger is positioned at the bottom, and the condensation unit 20' of the thermosyphon heat exchanger is positioned at the top.

한편, 써모싸이폰 열교환기의 증발부(10')와 응축부(20')는 단열되어야 하므로 써모싸이폰 열교환기의 증발부(10')와 응축부(20') 사이와 절곡부(3)를 기준으로 하는 두 부분의 관형 용기(1) 사이에 단열부(30)를 형성시킨다.On the other hand, since the evaporator 10 'and the condenser 20' of the thermosyphon heat exchanger are to be insulated, between the evaporator 10 'and the condenser 20' of the thermophone heat exchanger and the bent part 3 A thermal insulation portion 30 is formed between the two portions of the tubular container 1 based on).

상기 단열부(30)의 형성은 본 발명이 속하는 기술 분야에서 통상적으로 사용되는 방법으로 이루어질 수 있다.Formation of the heat insulating portion 30 may be made by a method commonly used in the art.

상기 하부의 관형 용기(1)에 작동유체(12)가 통과하는 냉각코일(11)이 설치되어지되 써모싸이폰 열교환기의 증발부(10') 후단에 설치되며, 써모싸이폰 열교환기의 증발부(10')가 설치되는 하부의 관형 용기(1) 유입부로 고온습공기가 유입되어 예냉각된 후, 작동유체(12)가 통과하는 냉각코일(11)을 통과하면서 냉각된 다음, 써모싸이폰 열교환기의 응축부(20')가 설치되는 관형 용기(1) 유출부를 통과하여 재가열된다.The cooling coil 11 through which the working fluid 12 passes is installed in the lower tubular container 1, but is installed at the rear end of the evaporation unit 10 ′ of the thermosyphon heat exchanger, and the evaporation of the thermosyphon heat exchanger. After the high temperature humid air is introduced into the tubular vessel 1 inlet part of the lower portion 10 'and is precooled, it is cooled while passing through the cooling coil 11 through which the working fluid 12 passes, and then the thermosyphon The heat is passed through the outlet of the tubular vessel 1 in which the condenser 20 'of the heat exchanger is installed and reheated.

또한, 써모싸이폰 열교환기의 응축부(20')가 설치되는 관형 용기(1) 유출부 후단에 종래의 재가열 수단(미도시)을 설치할 수 있다.In addition, a conventional reheating means (not shown) may be provided at the rear end of the tubular vessel 1 outlet where the condensation portion 20 'of the thermosyphon heat exchanger is installed.

본 발명에 적용되는 써모싸이폰 열교환기는 단일관형 또는 루프형 써모싸이폰 열교환기이다.Thermosyphon heat exchangers applied to the present invention is a single-tube or loop type thermosyphon heat exchanger.

즉, 도 4 및 도 5에 도시된 바와 같이 증발부(10)에서 작동 유체가 증발하고 응축부(20)와의 압력차가 발생해서 증발부(10)로부터 응축부(20)로 증기가 이동하며, 증기는 응축부(20)에서 증발잠열을 히트파이프 주위에 전달하고 응축되고, 응축된 액체는 중력에 의해 증발부(10)로 이송되는 단일관형 써모싸이폰 열교환기가 사용 가능하고, 고온고습의 열풍이 배출되는 곳에 증발기(13)가 설치되고, 제습된 공기가 배출되는 곳에 응축기(23)가 배치되며, 작동유체의 증기 유동관(14)과 액체 유동관(15)으로 증발기(13)와 응축기(23)를 연결 구성한 루프형 써모싸이폰 열교환기도 사용 가능하다.That is, as shown in FIGS. 4 and 5, the working fluid evaporates in the evaporator 10 and a pressure difference occurs with the condenser 20 so that steam moves from the evaporator 10 to the condenser 20. Steam transfers the latent heat of evaporation in the condenser 20 around the heat pipe and condenses, and the condensed liquid can be used in a single tube thermosyphon heat exchanger, which is transferred to the evaporator 10 by gravity, and hot air of high temperature and high humidity. The evaporator 13 is installed at the discharged place, and the condenser 23 is disposed at the place where the dehumidified air is discharged. The evaporator 13 and the condenser 23 are connected to the vapor flow pipe 14 and the liquid flow pipe 15 of the working fluid. Loop thermosyphone heat exchangers can also be used.

본 발명에 있어서, 써모싸이폰 열교환기의 증발부(10')는 제습전의 예비 냉각 기능을 하는 것이고, 써모싸이폰 열교환기의 응축부(20')는 재가열 열교환기와 같은 기능을 하는 재가열기로 사용됨으로써 에너지원의 사용없이 고온습공기의 예비 냉각에 의하여 에너지를 절약할 수 있을 뿐만 아니라 재가열시 필요한 에너지를 절감할 수 있게 된다.In the present invention, the evaporator 10 'of the thermosyphon heat exchanger serves as a pre-cooling function before dehumidification, and the condensation unit 20' of the thermosyphone heat exchanger serves as a reheater that functions as a reheat heat exchanger. By being used, it is possible not only to save energy by preliminary cooling of hot and humid air without using an energy source, but also to save energy required for reheating.

다음의 실시예는 본 발명을 좀 더 구체적으로 설명하는 것이지만, 본 발명의 범주를 한정하는 것은 아니다.The following examples illustrate the invention in more detail, but do not limit the scope of the invention.

각각 폐싸이클로 가동되도록 구성되는 실시예 1과 비교예 1의 건조기에 다음과 같은 조건이 되도록 가동한 후, 제습효과가 에너지 절약 효과를 측정 및 평가하한 결과, 실시예 1의 건조기는 제습효과가 300% 이상 상승하였고, 에너지는 30% 이상 절감되었다.After operating the dryers of Example 1 and Comparative Example 1 each configured to operate as a closed cycle, the following conditions were observed, and the dehumidification effect measured and evaluated the energy saving effect. As a result, the dryer of Example 1 has a dehumidification effect of 300. It has risen more than% and energy has been saved more than 30%.

즉, 건조기 내로 공급되는 초기 고온열풍의 온도를 75℃, 상대습도 15%, 절대습도 0.038kgw/kga(kgw = 물의 중량, kga = 공기의 중량)로 하고, 건조공정을 거친 후의 고온습공기의 온도 60℃, 상대습도 50%, 절대습도 0.044kgw/kga가 되도록 건조기의 조건을 설정한 다음, 건조공정을 거친 고온습공기를 제습 재가열하여 공급하면서 재순환되는 공기의 제습량과 재가열시 소요되는 가열량을 측정한 결과, 실시예 1에서의 제습량과 가열량은 각각 0.006kgw/kga, 14kcal/kg인 데 반하여 비교예 1에서의 제습량과 가열량은 각각 0.002kgw/kga, 20kcal/kg임을 알 수 있는 바, 제습효과가 300% 이상 상승하였고, 에너지는 30% 이상 절감됨을 확인할 수 있었다.In other words, the temperature of the initial high temperature hot air supplied into the dryer is 75 ° C, relative humidity 15%, absolute humidity 0.038kgw / kga (kgw = weight of water, kga = weight of air), and the temperature of the high temperature wet air after the drying process. After setting the condition of the dryer to be 60 ℃, 50% relative humidity, and 0.044kgw / kga absolute humidity, dehumidifying and reheating and supplying the dehumidified air after dehumidification and heating. As a result, the dehumidification amount and heating amount in Example 1 were 0.006kgw / kga and 14kcal / kg, respectively, whereas the dehumidification amount and heating amount in Comparative Example 1 were 0.002kgw / kga and 20kcal / kg, respectively. As a result, the dehumidification effect increased by more than 300%, the energy was found to be reduced by more than 30%.
