연소장치를 이용한 건조배기가스의 무폐수 탈취장치{Device for deodorizing and non-wastewater by regenerative thermal oxidizer of dry waste gas}Device for deodorizing and non-wastewater by regenerative thermal oxidizer of dry waste gas

본 발명은 하.폐수처리과정에서 발생하는 각종 슬러지를 재처리하는 건조기에 관한 것으로, 특히 건조기의 건조과정에서 발생하는 건조배기가스를 연소장치로 분해처리하여 탈취효율을 증대시킴은 물론 연소장치의 배출가스를 여과기로 보내어 폐수의 발생 없이 미세분진을 제거하도록 하며 연소장치에서 배출되는 열을 건조기의 열원인 보일러의 보조 열원으로 재활용시킬 수 있도록 한 연소장치를 이용한 건조배기가스의 무폐수 탈취장치에 관한 것이다.The present invention relates to a drier for reprocessing various sludges generated from wastewater treatment, in particular, by decomposing the dry exhaust gas generated during the drying process of the drier with a combustion device to increase the deodorization efficiency as well as the combustion device. The exhaust gas is sent to the filter to remove fine dust without generating waste water, and to the wastewater deodorization device of dry exhaust gas using the combustion device that recycles the heat discharged from the combustion device to the auxiliary heat source of the boiler which is the heat source of the dryer. It is about.

일반적으로, 하수나 폐수처리장의 각종 수처리공정에서 불가피하게 산업폐기물인 각종 슬러지가 발생하는데, 이 슬러지는 분리된 오물침사 또는 침전된 슬러지 또는 잉여활성슬러지 또는 부식토 등과 같은 각종 이물질을 함유하면서 덩어리나 죽 모양 또는 고체 모양을 이루게 된다.In general, various sludges, which are industrial wastes, are inevitably generated in various water treatment processes of sewage or wastewater treatment plants. It will be shaped or solid.

여기서, 상기 슬러지 침전물 중 유기성 침전물의 대부분은 미생물로 분해하 여 안전하고 무해한 물질로 바꾸는 소화과정을 거쳐 비료나 화력발전소 연료 등으로 재활용하며, 상기 활성슬러지 등은 수분을 제거하고 건조과정을 거쳐 보조연료나 퇴비 등으로 재활용하게 된다.Here, most of the organic precipitates in the sludge deposits are recycled to fertilizers or thermal power plant fuels through a digestion process that is decomposed into microorganisms and converted into safe and harmless substances, and the activated sludges are assisted by removing moisture and drying. It will be recycled as fuel or compost.

그러나, 상기 슬러지는 건조과정 등을 거쳐 재활용하는 것이 가능하지만, 건조과정에서 악취와 폐수발생으로 인해 처리가 곤란하였으며, 특히 슬러지의 해양 투기를 전면 금지하는 해양오염방지법이 발효됨에 따라 처리기술 및 공정이 요구되고 있는 실정이다.However, the sludge can be recycled through a drying process, etc., but it was difficult to treat due to bad smell and waste water during the drying process. This situation is required.

따라서, 상기 슬러지의 처리과정에서 발생하는 각종 악취나 폐수를 제거하기 위한 방법으로서, 활성탄을 이용하여 악취를 포집하는 탈취법, 악취물질을 연소하거나 촉매로 산화시키는 연소법, 미생물을 담지한 담체에 악취물질을 통과시키는 미생물 탈취법과 상용수로 미세분진을 제거하는 방법 등이 개발되어 있다.Therefore, as a method for removing various odors or wastewater generated during the treatment of the sludge, a deodorization method for collecting odors using activated carbon, a combustion method for burning odorous substances or oxidizing with a catalyst, odor in a carrier supporting microorganisms Microorganism deodorization method that passes the material and a method for removing fine dust with commercial water have been developed.

예컨대, 도 1에서와 같이, 탈취장치(100)는, 건조기(170)와, 상기 건조기(170)의 배출라인에 연속적으로 구성되어 이물질을 걸러주는 원심집진기(110)와 탈습탑(120), 및 상기 탈습탑(110)의 배출라인에 구성되어 상기 이물질을 외부로 압송하는 송풍기(130)로 이루어진다.For example, as shown in Figure 1, the deodorizer 100, the dryer 170, the centrifugal precipitator 110 and the dehumidification tower 120 that is continuously configured in the discharge line of the dryer 170 to filter foreign matter, And a blower 130 configured to discharge the dehumidification tower 110 to pump the foreign matter to the outside.

이때, 도 1에 기재된 미설명부호 '150'은 상기 탈습탑(120)의 미세분진을 제거시키고 냉각에 필요한 냉각수를 공급하는 냉각수공급라인이고, 미설명부호 '160'은 상기 탈습탑(120)의 작동과정에서 발생하는 미세분진이 포함된 폐수를 배출하기 위한 배출라인이며, 특히 상기 냉각수공급라인(150)에 공급되는 냉각수는 하수처리장의 방류수를 이용함이 바람직하다. In this case, reference numeral '150' described in FIG. 1 is a cooling water supply line for removing fine dust of the dehumidification tower 120 and supplying cooling water for cooling, and reference numeral 160 denotes the dehumidification tower 120. It is a discharge line for discharging wastewater containing fine dust generated during the operation of, in particular, the cooling water supplied to the cooling water supply line 150 is preferably using the discharge water of the sewage treatment plant.

그런데, 상기 슬러지처리장치(100)는, 상기 탈습탑(120)의 냉각수로 재활용하는 냉각수공급라인(150)을 포함한 냉각시스템을 구성해야 하므로 탈습 후 폐수의 재처리 비용이 발생함은 물론 용수사용량이 과다하여 상기 악취제거에 따른 각종 부대비용이 증대하는 문제점이 있었다.By the way, since the sludge treatment apparatus 100 must configure a cooling system including a cooling water supply line 150 for recycling the cooling water of the dehumidification tower 120, the wastewater reprocessing cost is generated as well as the water consumption. This excess has caused a problem of increasing the various incident costs associated with the removal of the odor.

그리고, 상기 슬러지처리장치(100)는, 상기 탈습탑(120)에 수분이 함유된 미세분진이 부착되는 경우 제거가 어려워 덕트나 데미스터의 막힘 현상이 발생하고, 이로 인해 분진의 제거효율이 저하되는 문제점이 있었다.In addition, when the sludge treatment apparatus 100 is attached to the dehumidification tower 120, it is difficult to remove the fine dust containing moisture, so that clogging of the duct or the demister occurs, and thus, the removal efficiency of dust is reduced. There was a problem.

이에, 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 건조기의 건조과정에서 발생하는 건조배기가스를 분해처리하여 폐수의 발생 없이 탈취효율을 증대시킴은 물론 건조배기가스의 처리과정에서 발생하는 열원을 재활용시킬 수 있도록 한 연소장치를 이용한 건조배기가스의 무폐수 탈취장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention was devised to solve the problems as described above, by decomposing the dry exhaust gas generated in the drying process of the dryer to increase the deodorization efficiency without the generation of waste water, as well as in the process of drying exhaust gas It is an object of the present invention to provide a wastewater deodorization device for dry exhaust gas using a combustion device to recycle a generated heat source.

Second, since the inlet temperature of the filter is controlled by using the heat of the combustion device, the waste water is not generated by removing the fine particles, so that wastewater is not generated due to the exhaust gas treatment, thereby saving operating costs.

셋째, 상기 제어기에 의해 상기 건조기의 내부압력을 조절하므로 건조 배기가스가 연속적으로 제거되어 건조기의 작동효율이 증대된다.Third, since the internal pressure of the dryer is controlled by the controller, the dry exhaust gas is continuously removed, thereby increasing the operating efficiency of the dryer.

넷째, 상기 연소장치의 배출 열을 건조기 보일러의 보조열원으로 사용함으로 건조에 필요한 연료비 절약을 하게 된다. Fourth, by using the exhaust heat of the combustion device as an auxiliary heat source of the dryer boiler to save the fuel cost required for drying.
