Description
본 발명은 각종 보일러 내부에 생성, 결착되는 관석을 방지 및 제거하고 보일러내부의 방청()에 사용되는 조성물에 관한 것이다.The present invention prevents and removes the capstone that is generated and bound inside the various boilers, and prevents the rust inside the boiler ( It relates to a composition used for).
더 상세히 설명하면, 본 발명의 조성물은 각종 산업용 보일러, 난방용 보일러, 선박의 기관보일러 등의 내부에 형성되는 관석의 방지, 제거 및 부식을 억제하기 위한 것으로서, 붕산나트륨, 에틸렌디아민 테트라아세트산 유도체, 음이온계면활성제, 몰리브덴유도체, 탄닌유도체로 이루어진 비인산계(非燐酸係) 조성물이다.In more detail, the composition of the present invention is for preventing, removing, and corrosion of capstone formed in various industrial boilers, heating boilers, engine boilers, etc. of a vessel, and sodium borate, ethylenediamine tetraacetic acid derivative, and anion. It is a non-phosphate composition which consists of surfactant, a molybdenum derivative, and a tannin derivative.
종래의 관석방지, 제거 및 부식억제용 조성물로는 본 발명자의 선출원인 특허원 제82-744호에 기재된 바와 같다. 상기 특허원 제82-744호 발명의 조성물이 우수함에 인정되었으나, 인산염을 사용하는 관계로 수질을 오염시키는 결점을 완전히 제거하지 못하였으며, 미국에서 시판되는 크롬제제는 저압보일러에만 국한될 뿐만 아니라, 수질 총경도 5ppm 이하의 연수에서 사용될때만 관석제거에 효과를 얻을 수 있으며, 관석방지에는 만족할만한 효과를 얻지 못했다. 더우기 이들 인산계제제나 크롬제제의 폐수가 하천이나 해수에 혼입되면 적조현상을 일으켜 어패류를 사멸시킬 뿐만 아니라 상수원에 혼입될때는 인체에 악영향을 미치므로 공해문제로 크게 대두되고 있다. 또한 근래 관석방지용 기구로 외국에서 수입된 “하이드로유니트”나 “이·더블유·티”(E.W.T)는 그 가격이 매우 비쌀 뿐만 아니라, 실제로 산업용 보일러에 설치해 본 결과 관석의 방지에는 다소 도움을 주나, 관석이 형성되었음을 발견하였으며, 또한 기존 결착된 관석에 대해서는 전혀 효과를 나타내지 못했다.Conventional capstone prevention, removal and corrosion inhibiting compositions are as described in Patent Application No. 82-744, which is a prior application of the present inventors. It was recognized that the composition of the patent application No. 82-744 was excellent, but did not completely eliminate the defects contaminating the water due to the use of phosphate, and the chromium agent commercially available in the United States is not only limited to low pressure boilers, When used in soft water of less than 5ppm total water hardness, it is possible to obtain the effect of removing the capstone, and did not obtain the satisfactory effect. Moreover, when the phosphate-based or chromium-based wastewater is mixed with rivers or seawater, it causes red tide and kills fish and shellfish. In addition, the "hydro unit" and "E. double U tee" (EWT) imported from foreign countries as a capstone prevention device are very expensive and they actually help to prevent capstones as a result of installation in industrial boilers. It was found that the capstone was formed, and also had no effect on the existing capstone.
이러한 여러가지의 결점을 해결하고자 본 발명자는 인산유도체난 크롬유도체가 함유되지 않은 제제를 개발하기 위하여 연구, 검토한 결과 붕산나트륨, 에틸렌디아민 테트라 아세트산 유도체(EDTA, H4Y) 음이온계면활성제, 몰리브덴유도체, 탄닌유도체를 일정비율로 혼합하여 사용한 결과 상기 결점이 일거에 해결된 우수한 세관, 청관제로 작용함을 발견하여 본 발명에 이르게 되었다.The present inventors in order to solve the drawbacks of these various phosphate derivatives I chromium research in order derivative is to develop a non-containing formulation, a review, sodium borate, ethylenediaminetetraacetic acid derivatives (EDTA, H 4 Y) anionic surfactants, molybdenum derivative As a result of using a mixture of tannin derivatives in a certain ratio, it was found that the above-mentioned defects acted as an excellent customs and cleansing agent, which led to the present invention.

상기의 음이온계면활성제란 여러가지 종류가 있으나, 용수중에서 거품을 일으키지 않는 것으로, 바람직한 것으로서는 리그닌설폰산염을 들 수 있으며, 이는 물의 연화, 관석생성방지, 부식방지, 가성취하방지, 분산효과를 나타내며, 이의 사용량은 총중량에 대해 1-15중량부, 더욱 바람직하기로는 3-9중량부이다.There are various kinds of the anionic surfactant, but it does not cause bubbles in water, and preferred examples thereof include lignin sulfonate, which shows water softening, capstone formation prevention, corrosion prevention, caustic dropping, and dispersion effect. Its usage amount is 1-15 parts by weight, more preferably 3-9 parts by weight based on the total weight.
보일러용수에 거품이 생길 경우에는 본 발명의 조성물에 실리콘오일과 같은 공지의 소포제를 가하여 사용하는 것이 바람직하다.When foaming occurs in the boiler water, it is preferable to add a known antifoaming agent such as silicone oil to the composition of the present invention.
상기의 몰리브덴 유도체란 인산몰리브덴, 몰리브덴산, 몰리브덴암모늄 등을 들 수 있으며, 이중 몰리브덴산과 몰리브덴암모늄이 특히 바람직하다. 이들 몰리브덴 유도체는 윤활, 촉매, 침투, 관석분해 등의 작용을 하는 것으로 사료되며, 이중 관석예방용으로는 몰리브덴암모늄, 관석제거용으로는 몰리브덴산이 바람직하며, 이들 사용량은 총중량에 대해 0.2-20중량부, 바람직하기로는 4-10중량부이다.Examples of the molybdenum derivatives include molybdenum phosphate, molybdate and molybdenum ammonium, with molybdenum and molybdenum ammonium being particularly preferred.

수원시에 소재하는 모공장의 산업보일러(연관식 5톤 보일러)에 자석식관석 부착방지 및 제거기(수입품)을 부착하여 약 1년간 부착하여 가동해본 결과, 4-5mm의 관석이 부착, 결석되었기에 이를 확인해본 결과 규산염과 황산염의 성분이 많았다. 이를 산세척하여 제거하고자 하였으나 제거할 수 없었다. 이러한 성분의 관석은 불화수소산으로 세척이 가능하나, 이는 시공상 위험하고 또한 보일러의 동체의 침식이 극심하기 때문에 시공할 수 없었다.The magnetic boiler attached to the industrial boiler (connected 5 ton boiler) in Suwon-si was attached and operated for about 1 year.The result was 4-5mm capstone attached and absent. As a result, there were many components of silicate and sulfate. It was pickled and removed but could not be removed. The capstone of these components can be washed with hydrofluoric acid, but this could not be done because of the danger of construction and the erosion of the boiler body.
이 보일러에 상기 조성물을 급수톤당 50g씩 가산하여 투입하고 약 1개월간 가동후, 개관하여 확인한 바 원래 결착된 백색의 관석이 흑갈색으로 변하여 용해 및 분해되어 탈락됨을 확인하였다. 이는 본 발명의 조성물이 흑갈색이 침투, 분해, 제거되었음이 명백하다. 다시 2개월간 계속 투입한 결과 보일러의 관석이 완전히 제거되었다.The composition was added to the boiler by adding 50 g per ton of water and operated for about 1 month. After opening, it was confirmed that the originally bound white capstone turned into black brown, dissolved and decomposed to be eliminated. It is evident that the composition of the present invention has penetrated, degraded, and removed dark brown. After another two months, the boiler was completely removed.

수질총경도 90~110ppm,탁도6NTU 수질의 공업용수를 사용하는 경기도 안양시 소재 모공장의 연관식 5톤보일러에 본 발명의 선발명인 관석방지 조성물이 아닌 일반 인산염 관석방지제를 사용하였으나, 관수의 수소이온농도(pH)가 기준치 미달이어서 청관제의 투입량을 증가시켜도 수소이온농도가 상승되지 않았다.Although the total phosphate capping agent was used in the associated 5 ton boiler of the parent factory in Anyang-si, Gyeonggi-do, which uses industrial water of 90 ~ 110ppm water quality and turbidity of 6NTU water quality, the phosphate capping agent was used. Since the pH was lower than the standard value, the hydrogen ion concentration did not increase even when the amount of the cleansing agent was increased.
일반 관석방지제의 투입으로 수소이온농도가 조정불가능하였던 것은탁도6NTU이며, 수질에 본 발명자의 선특허가 아닌 일반 인산염 관석방지제를 사용하면 관수가 혼탁되어 송증기와 함께 관수가 따라 넘어감으로 인한 것이다.It was turbidity 6NTU that the hydrogen ion concentration could not be adjusted by the input of the general capstone inhibitor, when the non-patent general phosphate capstone inhibitor is used in the water quality due to the turbidity of the water and the water flow along with the pump .
상술한 본 조성물을 투입한바 기준치인 pH 10 이상 상승되어 지속하였다. 본 조성물을 급수톤당 15g씩 가산하여 투입하여 1개월간 사용한후 개관하여 확인한바, 부착된 관석의 일부가 제거되었으며, 제거된 철관표면부위에는 흡갈색 피막이 형성되었으며 조성물 사용후 관석이 결착되지 않았다.When the above-described composition was added, the pH was raised to pH 10 or higher and continued. The composition was added to 15 g per ton of water and used for one month and then opened and confirmed. Part of the attached capstone was removed, and a brownish brown film was formed on the removed iron tube surface, and the capstone was not bound after the composition was used.
상기 조성물을 수질총경도 10ppm 이하의 용수를 사용하는 부산 소재 모산업체 10톤보일러에 급수톤당 5g씩 가산 투입하고 1개월간 가동한후 개관한 결과 관석부착이 전혀 없고 흑갈색 피막이 형성하였음을 알 수 있다.The composition was added to the 10-ton boiler in Busan, which uses water with a water hardness less than 10 ppm, and added 5 g per ton of water and operated for one month.
또 상기 조성물을 구미공단 모염직공장에서 증발량 20톤 고압보일러에 급수톤당 4g씩 가산하여 1개월간 사용한 후 개관해본 결과 기존결착된 관석이 모두 제거되고 관석이 전혀 부착되지 않았다.In addition, the composition was added to 4g per ton of water in a 20-ton high-pressure boiler at a Gumi industrial dyeing factory, and after one month of use, an overview of the existing capstone was removed and no capstone was attached.
