Description
본 발명은 세탁시설중 건조기의 건조 방법에 관한 것이다.The present invention relates to a drying method of a dryer in a laundry facility.
도 1은 일반적인 세탁시설의 건조장치를 나타낸 구성도이다. 도 1에 도시된 바와 같이 일반적인 건조장치는 크게 버너(101), 열공급장치(108), 건조실(104,105)로 구성되어 있으며 열교환기(102)에서 얻어진 열은 건조실(104,105)로 유입되어 세탁물 건조후 블로어(106,107)에의해 외부로 배기가 이루어진다.1 is a block diagram showing a drying apparatus of a general laundry facility. As shown in FIG. 1, a general drying apparatus includes a burner 101, a heat supply device 108, and drying chambers 104 and 105, and the heat obtained from the heat exchanger 102 flows into the drying chambers 104 and 105 after drying the laundry. Exhaust is made to the outside by the blowers 106 and 107.
도 2는 상기 기존 세탁물 건조장치의 간접가열식열 공급장치(205)를 설명한 것으로서 버너(201)에 의해 주입된 연료를 연소시키는 연소로(204), 연소된 뜨거운 공기의FIG. 2 illustrates the indirect heating type heat supply device 205 of the conventional laundry drying apparatus, and includes a combustion furnace 204 for burning fuel injected by the burner 201 and burned hot air.
열을 회수하는 열교환기(202)와 열 회수가 되지 않고 배출되는 연소공기의 배출구 Heat exchanger 202 for recovering heat and outlet of combustion air discharged without heat recovery
(203)로 상기 간접가열식 열공급장치가(205) 구성되며 열교환기(202)에서 회수되지 203, the indirect heating type heat supply device 205 is configured to recover the heat exchanger 202.
못한 열은 배출구(203)에 의해 외부로 배출되도록 구성되어있다.Unsuccessful heat is configured to be discharged to the outside by the outlet 203.
간접가열식은 열교환 효율이 40~50%에 불과해 연료의 소모가 많아 년간 연료비가 세탁물건조장치 1대당 약 일천오백만원이든다. 열회수 효율을 높이기 위해서는 열교환기(202)의 표면적과 부피가 증가하여야 하나, 열교환기의 표면적과 부피의 증가는 열교환기(202)의 제작비가 높아져 가격 경쟁력을 잃고 또한 건조장치를 건물내에 설치하는데 있어 그 부피가 커져 설치에 어려움이 있다.Indirect heating type heat exchange efficiency is only 40-50%, so the fuel consumption is high, the annual fuel cost is about 15 million Yuan per laundry dryer. In order to increase the heat recovery efficiency, the surface area and volume of the heat exchanger 202 must be increased. However, the increase in the surface area and volume of the heat exchanger results in a high manufacturing cost of the heat exchanger 202, which leads to a loss of price competitiveness and the installation of a drying apparatus in the building. Its bulkiness makes installation difficult.
본 발명은 상기 종래기술이 안고 있는 간접가열식 열공급방식은 열 회수율이 낮은 문제점을 해결하기 위하여 안출된 것으로 열 회수 효율의 극대화 뿐만 아니라 세탁 건조시간 단축 및 기존 대비 50%이상의 연료 절감 효과를 볼수 있으며 그 구조가 간단하여 매우 실용적이고 유용한 세탁물건조기의 열공급 방법을 제공하는 것을 그 목적으로 두고 있다.The present invention has been conceived in order to solve the problem of low heat recovery rate of the indirect heating type heat supply method of the prior art can not only maximize the heat recovery efficiency, but also reduce the drying time of washing and fuel savings of more than 50% compared to the conventional The object of the present invention is to provide a method of supplying heat to a laundry dryer that is simple in structure and very useful.
상기와 같은 목적을 달성하기 위하여 본 발명은 건조실 내에 열 공급방법이 직접가열식인 것을 그 특징으로 한다. 기존의 간접가열식은 연소된 열이 열교환기의 열 전도에 의해 일부 열회수는 되나 절반 이상의 열이 회수가 되지 않은 상태로 배출구(203)를 통해 외부로 배출되는데 비해, 본 발명의 직접 가열식 열공급장치는 배출구(303)에서 배출되어지는 폐열이 송풍기(403)에 의해 유입되는 공기(306)와 섞여 건조실(404,405)로 유입 시키게 되는 것으로서 외부로 열 에너지를 배출시키지 않고 모두 사용하는 열 공급방법이다.In order to achieve the above object, the present invention is characterized in that the heat supply method in the drying chamber is a direct heating type. In the conventional indirect heating type, the heat is burned out by heat conduction of the heat exchanger, but the heat is discharged to the outside through the outlet 203 in a state where at least half of the heat is not recovered. The waste heat discharged from the discharge port 303 is mixed with the air 306 introduced by the blower 403 to be introduced into the drying chambers 404 and 405, and is a heat supply method using all of them without discharging thermal energy to the outside.
상기의 직가열식 연소에있어 완전연소 되기 위해서는 버너(401)에서 점화된 연료와 버너블로어에서 유입된 공기가 연소로에서 500~1200℃로 0.2~3초간 연소가 가능하나, 효율적인 면과 경제적인 면에서 800~1000℃에서 0.5~2초간 연소하는 것이 In order to be completely burned in the direct heating combustion, the fuel ignited in the burner 401 and the air introduced from the burner blower can be burned for 0.2 to 3 seconds at 500 to 1200 ° C. in the combustion furnace, but it is efficient and economical. Burning at 800 ~ 1000 ℃ for 0.5 ~ 2 seconds
좋다. 열교환기효율이 낮아도 발생되어지는 열은 배출구(303)가 열 공급장치 내부에 있으므로 연소로(304)에서 발생한 모든 열이 건조실(404,405)로 유입된다. 그러므로 운전비용면에서 경제적이며 또한 열교환기가 작아도 되므로 제작적인 면에서도 경제적이다.good. Even though the heat exchanger efficiency is low, since the outlet 303 is inside the heat supply device, all the heat generated from the combustion furnace 304 is introduced into the drying chambers 404 and 405. It is therefore economical in terms of operating cost and economical in terms of production since the heat exchanger can be small.
상기 직접가열식 열공급장치(305)의 연료는 경유, 등유, LPG, LNG등을 연료로 사용할 수 있으나 좋기로는 청정연료인 LPG와LNG가 좋다.Fuel of the direct heating type heat supply device 305 may be diesel, kerosene, LPG, LNG, etc. as a fuel, but preferably LPG and LNG, which are clean fuels.
도 3은 상기의 직접가열식 열 공급장치를 설명하기 위한 개략적인 시스템 개요도로서, 송풍기(403)에 의해 건조실(404,405)로 유입되는 공기(306), 연료주입과 점화가 가능한 버너(301)에서 점화된 연료를 연소로(304)에서 완전 연소된 후 열교환기(302)를 통해 송풍기에 유입된 공기(306)에 열을 공급한다. 열공급은 연소로의 외벽을 스치며 가열되어지는 1차열과 연소배출구(302)에서 배출된 2차열로 구성되어지며, 연소로(304)는 두 공기가 충분히 혼합할 수 있도록 배플 역할을 한다. 이때 충분히 혼합된 공기(307)는 건조실 내부로 유입된다.FIG. 3 is a schematic system schematic diagram for explaining the above-described direct heating type heat supply device, and the air 306 introduced into the drying chamber 404 and 405 by the blower 403, and the ignition in the burner 301 capable of fuel injection and ignition. After the fuel is completely burned in the combustion furnace 304, heat is supplied to the air 306 introduced into the blower through the heat exchanger 302. The heat supply is composed of a primary heat that is heated and rubs the outer wall of the combustion furnace and a secondary heat discharged from the combustion outlet 302, and the combustion furnace 304 serves as a baffle to allow the two air to be sufficiently mixed. At this time, the sufficiently mixed air 307 is introduced into the drying chamber.
열교환기를 통해 열을 회수하는 간접가열식 열공급장치(205)는 열 회수효율이 45~50%정도로 열 회수율이 낮아 연료 소모가 높으나 본 발명에서 개발한 직접가열식 열공급장치(305)는 연소열을 전부 사용함으로써 열 회수 효율이 100%이므로 연료 소모를 최대로 낮추었다 또한 절반 용량의 버너를 사용하며, 작은 용량의 버너사용에 의해 연소실(204) 균열 발생이 적어 이로 인하여 발생되어지는 연소실(204) 교체 비용이 줄어 매우 실용적이다. The indirect heating type heat supply device 205 for recovering heat through the heat exchanger has a high heat recovery rate of about 45-50%, resulting in high fuel consumption, but the direct heating type heat supply device 305 developed in the present invention uses all the combustion heat. Since the heat recovery efficiency is 100%, the fuel consumption is reduced to the maximum. Also, a half-capacity burner is used, and the combustion chamber 204 is less likely to crack due to the use of a small-capacity burner, thereby reducing the cost of replacing the combustion chamber 204. Reduced is very practical.
