Description
본 고안은 여과포 보호를 위한 순환장치에 관한 것으로, 보다 상세하게는 중·소형 소각시설의 여건상 준연속 또는 단속 운전이 되므로, 상기 소각시설의 운전을 종료한 후 다음 운전시까지 상기 내부 기체의 온도변화로 인하여 여과 집진기 내의 여과포에 발생하게 되는 결로현상을 방지하기 위해 상기 내부기체 온도를 일정하게 유지하면서 이를 순환시켜 상기 여과포에 발생될 수 있는 눈막힘 현상을 방지하기 위한 여과포 보호를 위한 순환장치에 관한 것이다.The present invention relates to a circulator for protecting the filter cloth, and more particularly, the semi-continuous or intermittent operation of the medium and small incineration facilities, so that the internal gas of the internal gas until the next operation after the operation of the incineration facility is terminated. Circulator for protecting the filter cloth to prevent clogging that may occur in the filter cloth by circulating it while keeping the internal gas temperature constant to prevent condensation on the filter cloth in the filter bag due to the temperature change. It is about.
첨부된 도 1에서와 같이, 중·소형 규모의 일반적인 소각시설의 처리 공정을 살펴보면 다음과 같다.As shown in FIG. 1, the process of a general incineration plant of medium and small scale is as follows.
도 1에 도시된 바와 같이, 일반적인 폐기물 소각시설(100)에 폐기물을 투입하고, 이를 소각하게 되면 열, 가스 및 분진 등의 배출가스가 발생하게 되고, 상기 배출가스는 열교환 시설(110)에서 물 또는 공기에 의해 배출가스를 대략 250??정도의 온도로 냉각시키게 되며, 상기 열교환 시설(110)에 의해 냉각된 가스는 유해가스 처리시설(120)에서 산성가스 및 유해가스를 제거한 다음 분진제거 시설(이하 "여과 집진기"라 함)에서 미세분진을 제거하게 된다. 이렇게, 미세분진이 제거된 배출가스는 소각시설(100)의 외부로 배출을 용이하게 배출시키는 유인송풍기(140)를 통해 연돌(150)에 의해 외부로 배출하게 되는 것이다.As shown in FIG. 1, when waste is input to a general waste incineration plant 100, and incineration thereof, exhaust gases such as heat, gas, and dust are generated, and the exhaust gas is water in a heat exchange facility 110. Alternatively, the exhaust gas is cooled to a temperature of about 250 ° by air, and the gas cooled by the heat exchange facility 110 removes acidic gases and harmful gases from the noxious gas treatment facility 120 and then removes dust. (Hereinafter referred to as "filtration dust collector") to remove the fine dust. As such, the exhaust gas from which the fine dust is removed is to be discharged to the outside by the stack 150 through the manned blower 140 to easily discharge the discharge to the outside of the incineration facility (100).
상기와 같이, 종래 중·소형 소각로는 운전 여건상(폐기물 발생량, 작업자의 운전조건등) 연속운전이 어려운 문제로 인하여 준연속 또는 단속으로 운전이 이루어지고 있는 실정이다.As described above, the conventional medium and small incinerators are operated in semi-continuously or intermittently due to a problem that continuous operation is difficult due to operating conditions (waste generation amount, operator's operating conditions, etc.).
그러나, 상기와 같은 소각로는 준연속 및 단속운전시 가장 크게 문제가 되는 것은 여과집진기 내부의 여과포가 수분에 노출되어 여과포의 눈막힘현상으로 인해 수명이 현저하게 줄어들어 장기간 사용이 어렵게 된다.However, the incinerator as described above is the biggest problem during semi-continuous and intermittent operation is that the filter cloth inside the bag filter is exposed to moisture, the life of the filter bag is significantly reduced due to clogging phenomenon of the filter is difficult to use for a long time.
또한, 상기 여과 집진기(130) 내의 여과포의 특성상 수분이 부착되면 여과포 눈막힘현상 등으로 그 수명이 현저하게 줄어들어 교체시기가 빨라지게 되고, 소각시설(100)에서 사용되는 여과포는 일반 여과포에 비해 가격이 고가이어서 교체시에상당한 비용이 들어가는 문제점을 않고 있다.In addition, when moisture is attached due to the characteristics of the filter cloth in the filter dust collector 130, the life of the filter cloth is significantly reduced due to clogging of the filter cloth and the replacement time is faster, and the filter cloth used in the incineration facility 100 is more expensive than the general filter cloth This is expensive and does not have a problem of considerable cost in replacement.
한편, 폐기물 소각시설이 준연속 및 단속 운전시 각 관로의 온도 저하로 인하여 결로현상이 많이 발생되고, 발생되어지는 결로현상으로 인해 기기부식 및 기계 노후가 빠르게 진행됨에 따라 그에 따른 유지보수비가 연속운전 소각시설에 비해 많이 소요되며, 특히 온도가 낮은 겨울철이나 대기중 습기가 많은 날에는 더욱 심각한 문제점을 내포하고 있다.On the other hand, when waste incineration facilities are quasi-continuous and intermittent operation, many condensation occurs due to the drop in temperature of each pipeline, and the maintenance costs are continuously operated according to the rapid progress of equipment corrosion and machine aging due to the condensation that occurs. Compared to the incineration facility, it takes more time, especially in winter when the temperature is low or when the air is humid.
상기와 같은 문제점을 해소하기 위한 것으로, 본 고안은 중·소형 소각시설의 여건상 준연속 또는 단속 운전이 되므로, 상기 소각시설의 운전을 종료한 후 다음 운전시까지 상기 내부 기체의 온도변화로 인하여 여과 집진기 내의 여과포에 발생하게 되는 결로현상을 방지하기 위해 상기 내부기체 온도를 일정하게 유지하면서 이를 순환시켜 상기 여과포에 발생될 수 있는 눈막힘 현상을 방지하도록 하는데 그 목적이 있다.In order to solve the above problems, the present invention is a semi-continuous or intermittent operation in the conditions of the medium and small incineration facilities, due to the temperature change of the internal gas until the next operation after the operation of the incineration facility The purpose of the present invention is to prevent clogging that may occur in the filter cloth by circulating it while maintaining the internal gas temperature to prevent condensation occurring in the filter cloth in the filter bag.
