Field of the Invention The present invention relates to a high-viscosity contaminant processing method for treating a high-viscosity contaminant at the downstream of a tentering industry tenter using cleaning dust collection, dehumidification / heating and electrostatic dust collection,

TECHNICAL FIELD The present invention relates to a process for treating highly viscous contaminants downstream of a dyeing business tenter using cleaning dust collection, dehumidification / heating, and electrostatic dust collection. More particularly, the present invention relates to a process for treating high- The gas includes an organic solvent such as aldehydes, oil mist, and VOCs, a scraper that cleans and collects foreign matters such as napkins and bristles, a heat exchanger that dehumidifies moisture in the exhaust gas, and an electric dust collection system by corona discharge. The present invention relates to a process for treating highly viscous contaminants downstream of a dyeing tent by using cleaning dust collection, dehumidification / heating and electrostatic dust collection, which can exhibit improved recovery efficiency by recovering organic solvents such as water, oil mist and VOCs.

일반적으로 염색업종의 산업시설에 있어 다림질기계로 사용되는 텐터(TENTER)는 일명 폭출기(幅出機)라고도 하는 장치로서, 염색 다듬질 공정에서 천의 폭을 일정하게 하기 위하여 직물의 양쪽 귀를 핀 또는 클립으로 쥐고 천을 증기 속을 달리게 하는 장치이다.TENTER, which is generally used as an ironing machine in the industrial facility of dyeing industry, is also called a tentering machine. In the dyeing finishing process, a tenter is used to pin both ears of the fabric Or a device that holds the cloth and runs the cloth in the steam.

위와 같이 천의 폭을 일정하게 하기 위하여 염색 다듬질 공정에서 다림질기계로 사용되는 텐터는 대기환경보전법에 의거 대기오염물질 배출시설 및 생활악취 규제대상시설로 규정되어 대기오염방지시설을 필히 갖추어야 한다.The tenter used as the ironing machine in the dyeing finishing process in order to make the width of the fabric uniform as above is prescribed as air pollutant discharge facility and life odor control facility in accordance with the Air Quality Preservation Act, and air pollution prevention facilities must be provided.

이러한 텐터의 대기오염방지시설로는 초기에 입상활성탄 흡착탑만을 설치한 경우가 있었으나, 이는 온도에 따른 활성탄의 흡착능력을 고려하지 않은 결과라 할 수 있으며, 고유한 활성탄의 성질상 활성탄에 물질이 정상적으로 흡착될 수 있는 온도는 40~50℃ 미만으로써, 텐터에서 배출되는 배기가스의 평균 온도인 120~170℃로 배출되는 배기가스에서는 활성탄에 오염물질이 흡착되지 않을 뿐만 아니라 고온의 배기가스로 인해 활성탄이 발화되는 등의 위험성이 있는 것이다.As the air pollution prevention facility of such a tenter, only the granular activated carbon adsorption towers were installed in the early stage. However, this is a result of not considering the adsorption ability of activated carbon depending on the temperature, The temperature that can be adsorbed is less than 40 to 50 ° C. In the exhaust gas discharged at an average temperature of 120 to 170 ° C. of the exhaust gas discharged from the tenter, contaminants are not adsorbed on the activated carbon, There is a danger that such an ignition occurs.

또한, 상기와 같은 이유뿐만 아니더라도 고온상태로 배출되는 텐터의 배출가스 중 악취유발물질 등을 온도저하 없이 활성탄만으로 제거한다는 것은 매우 곤란하다는 것을 알 수 있는 것이다.It is also found that it is very difficult to remove odor-causing substances and the like from the exhaust gas of the tenter which is discharged at a high temperature state only by the activated carbon without lowering the temperature.

한편, 상기와 같은 초기의 텐터 대기오염방지시설을 개량한 기술로 상기 입상활성탄 흡착탑에 배기가스의 온도저하를 위하여 습식 세정시설을 추가한 기술이 개발되어 있으나, 이러한 설비는 활성탄의 재생 및 교체주기가 짧음과 아울러 재생 및 교체작업의 어려움과 비용 문제로 인해 활성탄의 교체 없이 2년 이상 그대로 가동하는 경우가 허다하였으며, 근래에는 습식세정과 함께 흡착탑이 일체로 형성되는 일체 타워형 방지시설을 설치하는 추세이다.Meanwhile, a technique has been developed in which a wet cleaning facility is added to the granular activated carbon adsorption tower in order to lower the temperature of the exhaust gas by the technique of improving the initial tenter air pollution prevention facility as described above. However, And it is difficult to reproduce or replace it. In addition, due to the cost problem, the activated carbon remains operating for more than 2 years without replacement of the activated carbon. In recent years, there has been a tendency to install an all- to be.

이때, 상기 일체식의 텐터 배기가스처리시설은 설치비가 저렴하고 외관이 좋은 장점을 지니고 있으나 수분과 고점성 오염물질인 오일미스트 및 낙모와 기모와 같은 이물질이 활성탄에 부착되어 폐색이 발생하는 경우가 빈번함과 아울러 오일미스트는 세정 및 흡착시설 외에 덕트에도 부착되어 오염을 일으키고 간혹 화재의 원인이 되는 등 제반 문제점이 있는 것이었다.At this time, although the integrated tenter exhaust gas treatment facility has advantages such as low installation cost and good appearance, there is a case in which foreign substances such as oil mist, dirt, and bristles, which are moisture and high viscosity pollutants, In addition to the frequent occurrence, the oil mist is adhered to the duct in addition to the cleaning and adsorption facilities, causing pollution and sometimes causing a fire.

상기와 같은 선례에서 보듯 많은 자금을 투자하여 환경오염방지시설을 해당 업체에 설치한 후 초기에만 가동하는 형식을 취하다가 기계적, 설비적 또는 관리적인 문제로 사장되는 오염방지시설이 대부분이었고, 설치된 후 효율적이고 지속적인 관리가 이루어지지 않아 그 실용성에 많은 문제점이 있는 것이었다.As shown in the above example, most of the pollution prevention facilities, which were installed in the initial stage after the installation of the pollution prevention facilities in the facilities by investing a lot of money, were installed due to mechanical, equipment or management problems. There were many problems in practicality because efficient and continuous management was not performed.
