본 발명은 마이컴부를 통해 중량측정형 호퍼로부터 측정된 순환골재·건설폐토석의 중량에 따라 드라이아이스생성장치에서 생성된 드라이아이스를 pH 저감밀폐공간부에 투입시켜 순환골재·건설폐토석을 드라이아이스에 의한 이산화탄소반응에 의해 pH를 8.6∼9.8이하로 저감시키는 드라이아이스를 통한 순환골재·건설폐토석 pH 저감장치 및 방법에 관한 것이다.
According to the present invention, dry ice produced in a dry ice producing device is added to a pH reducing closed space according to the weight of circulating aggregate and construction waste soil measured from a weighing-type hopper through a microcomputer unit to dry ice of circulating aggregate and construction waste soil. The present invention relates to a circulating aggregate and construction waste soil pH reduction device and method through dry ice for reducing the pH to 8.6 to 9.8 or less by a carbon dioxide reaction.

산업 현장에서 배출되는 건설폐기물은 건설폐기물의 재활용촉진에 관한 법률에 의거하여, 친환경적으로 적정처리하고 재활용을 촉진하여 국가자원의 효율적 이용은 물론 국민경제발전과 공공복리증진에 기여함을 목적으로 활용하도록 규정되어 있다.Construction wastes discharged from industrial sites are used for the purpose of contributing to the efficient use of national resources as well as to the national economic development and public welfare by pursuing environmentally sound and appropriate recycling in accordance with the law on the promotion of recycling of construction wastes. It is prescribed to

건설 폐기물의 재활용 촉진을 위하여 재활용 용도를 도로공사용, 건설공사용, 주차장 또는 농로의 표토용, 콘크리트용 등 다양한 용도로 사용하도록 법률로 규정하였으며, 이를 위해 건설폐기물을 파분쇄, 분리선별공정 등을 거쳐 순환골재·건설폐토석을 생산하게 되는데, 법률에 정한 순환골재·건설폐토석의 품질기준에 적합하게 한 것을 사용하도록 하였다.In order to promote the recycling of construction wastes, the law stipulates that the recycling uses for various purposes such as road work, construction work, parking lot or farm road surface, concrete use, etc. Recycled aggregates and construction waste soils will be produced, and those that meet the quality standards of recycled aggregates and construction waste soils are required.

법률에 정한 순환골재·건설폐토석의 품질기준은, 재활용 용도에 따라 차이가 있지만 도로공사용 순환골재의 입도와 순환골재의 품질로 소성지수, 마모감량, 안정성 등이 기준에 적합하여야 하고, 이물질 함량이 유기이물질 1%(용적기준)와 무기이물질 5%(질량기준)이하이어야 하도록 규정하고 있다.The quality standards of recycled aggregate and construction waste soil according to the law vary depending on the purpose of recycling, but the plasticity index, wear loss, stability, etc. should meet the criteria due to the particle size and recycled aggregate quality of road aggregate. It is regulated to be 1% (by volume) of organic foreign matter and 5% (by mass) of inorganic foreign matter.

그러나, 순환골재·건설폐토석을 재활용 용도에 따라 법률이 정한 순환골재·건설폐토석의 품질기준에 맞게 사용하더라도, 재활용된 순환골재·건설폐토석은 강우나 지하수에 의하여 순환골재·건설폐토석에서 강 알카리성 침출수가 생기게 된다.However, even if recycled aggregates and construction waste soils are used in accordance with the quality standards of recycled aggregates and construction waste soils according to the law for recycling purposes, recycled recycled aggregates and construction waste soils are recycled aggregates and construction waste soils due to rainfall or groundwater. In the river alkaline leachates are produced.

순환골재·건설폐토석에서 생긴 침출수는 폐콘크리트의 성분에 의하여 수소이온농도가 보통 pH 12.0 이상의 강 알카리성이므로, 순환골재·건설폐토석의 재활용 지역은 강우나 지하수에 의해 수질오염이 생기는 것이 당연할 것이다.Since leachate from circulating aggregate and construction waste soils is strongly alkaline due to the composition of waste concrete, the concentration of hydrogen ions is usually higher than pH 12.0. Therefore, it is natural that water pollution is caused by rainfall or groundwater in the recycling area of circulating aggregate and construction waste soil. will be.

순환골재·건설폐토석의 재활용 지역은, 수질오염에 의하여 어류가 죽게 되고, 물과 함께 생활하는 조류도 죽게 되어 생태계를 교란 시키게 되어 환경오염 지역으로 될 수밖에 없다.In the recycling area of recycled aggregate and construction waste soil, fish are killed by water pollution, and algae living with water are also killed, disrupting the ecosystem and becoming an environmental pollution area.

따라서, 법률에 정한 순환골재·건설폐토석의 품질기준에는 순환골재·건설폐토석의 침출수에 대한 규정이 있어야 하며, 순환골재·건설폐토석에서 생기는 강 알카리성 침출수를, 사전에 강 알카리성 침출수가 나오지 않게 처리하여 강 알카리성 침출수가 나오지않는 순환골재·건설폐토석으로 수질오염을 없애고 안전한 순환골재·건설폐토석을 사용할 수 있게 하는 장치 및 방법이 요구하고 있다.Therefore, the quality standards of recycled aggregates and construction waste soils must be defined in the legislation for the leachate of recycled aggregates and construction waste soils, and the strong alkaline leachate generated from recycled aggregates and construction waste soils will not come out in advance. There is a need for an apparatus and method for removing wastewater by using recycled aggregates and construction waste soils that do not have strong alkaline leachate, and allowing the use of safe recycled aggregates and construction waste soils.

하지만, 기존의 순환골재·건설폐토석 pH 저감장치는 연속생산이 아니기 때문에 시간당 처리용량이 매우 작아 현실적으로 적용하기 어렵고 적용하기 위해서는 병렬로 많은 시설을 설치해야 하는 문제점이 있었다.However, the existing recycled aggregate, construction waste soil pH reduction device is not a continuous production, so the processing capacity per hour is very small, it is difficult to apply realistically, there was a problem to install a lot of facilities in parallel to apply.

또한, 반응을 위한 일정 부분의 수분을 공급해주는 장치도 없고, 이산화탄소(CO2)와 수산화기(OH-)의 반응인 중성화반응을 촉진하기 위해 별도의 열원을 공급해주는 장치가 없으며, 이산화탄소의 압력을 높이기 위해서는 압력을 높이기 위한 별도의 장치가 반드시 있어야 하고 이로 인한 배관의 파손이 쉽게 일어나기 때문에 높은 기압으로 올리기가 어려운 문제점이 있었다.
Furthermore, no device that supplies water in a portion for the reaction, carbon dioxide (CO 2) and hydroxyl group (OH -) there is no apparatus that supplies additional heat source to promote the reaction in the neutralization reaction of, the pressure of the carbon dioxide In order to increase the pressure must be a separate device to increase the pressure caused by this easily caused by the damage of the pipe was difficult to raise the high pressure.
