Description

이온스크러버 재생액 순환펌프{Scrubber circulating pump}Ion scrubber regenerating liquid circulating pump {Scrubber circulating pump}

본 발명은 이온스크러버에 사용되는 재생액 순환펌프에 관한 것으로서, 특히, 재생액 순환펌프에서 이탈되는 수용액의 압력과 양을 억제하여 펌프의 효율을 높이고, 미량의 수용액을 이동시켜 하부베어링에 항상 일정한 적정량의 윤활이 되도록 하여 베어링 수명을 극대화할 수 있도록 한 재생액 순환펌프를 제공하기 위한 것이다.The present invention relates to a regenerant circulation pump used in an ion scrubber. More particularly, the present invention relates to a regenerant circulation pump used in an ion scrubber, And to provide a regenerant circulation pump capable of maximizing the life of the bearing by lubrication of an appropriate amount.

대기오염환경의 유해가스 제어 및 정화기술인 이온스크러버는 이온교환섬유를 재생하여 운용된다.Ion scrubbers, which control and purify noxious gases in air pollution environments, operate by regenerating ion exchange fibers.

이온스크러버 재생액 순환펌프는 오염물질이 흡착된 이온카트리지를 재생 및 복원시키기 위하여 이온스크러버 하부 재생액 탱크에 황산 5% 또는 알카리 5% 수용액을 채워 재생액 상부로 보내며 로터가 회전하면서 재생액을 분사하여 이온교환섬유에 부착된 오염물질을 탈착시키는 이온스크러버의 성능에 중요한 역할을 하게 된다.Ion scrubber regeneration liquid circulation pump is filled with 5% sulfuric acid or 5% alkali solution in ion regenerator tank to regenerate and recover the ion cartridge adsorbed contaminant, and sends it to the top of regeneration liquid. Which plays an important role in the performance of the ion scrubber to desorb the contaminants attached to the ion exchange fiber.

재생액 순환펌프는 입형, 수중형으로 펌프는 수용액에 잠기고 모터는 상부에 노출되는 구조이다.The regeneration liquid circulation pump is of the mouth type and underwater type, the pump is immersed in the aqueous solution and the motor is exposed at the top.

수용액에 항상 잠겨있는 재생액 순환펌프는 내구성을 고려하여 임펠러 및 케이싱등이 산, 알카리 수용액에 충분히 견디는 비금속 FRP 재질로 제작되며 모터에 펌프축을 연결하여 수용액을 펌핑하는 임펠러는 모터 아래에 볼베어링을 설치하여 흔들리는 힘과 쳐지는 힘을 잡아주고 수용액 아래까지 담겨야하는 긴 펌프축은 펌프 케이싱에 하부베어링으로 펌프축을 지지해서 흔들림을 잡아 주어야 한다.The regenerant circulation pump, which is always immersed in the aqueous solution, is made of non-metallic FRP material that can withstand the acid and alkaline aqueous solution of the impeller and casing in consideration of durability. The impeller that pumps the pump by connecting the pump shaft to the motor is equipped with a ball bearing The long pump shaft, which should hold the shaking force and the striking force, should be kept under the aqueous solution, should support the pump shaft by the lower bearing on the pump casing, and shake it.

일반 물 펌프의 경우 하부베어링의 지지는 메탈베어링으로 구리스 윤활하는 방법, 고무베어링에 청수를 사용하는 방법이 일반적으로 사용되고 있지만 재생액 순환펌프를 지지하는 하부베어링 경우는 수용액이 변질되면 절대 않되며 내약품성이 탁월해야 되는 점을 감안하여 이에 따른 베어링재료와 윤활방법이 채택되어야 하나 통상 메탈베어링으로 사용하여 그 수명이 현저하게 짧아지는 단점이 있는 것이다.In the case of general water pumps, a method of lubricating grease with a metal bearing and a method of using fresh water in a rubber bearing are generally used for supporting the lower bearing. However, in the case of the lower bearing supporting the regenerating fluid circulating pump, Bearing materials and lubrication methods should be adopted in view of the superior chemical resistance, but they are usually used as metal bearings, which shortens the life span remarkably.
