본 발명은 이온교환수지 재생탱크에서 역세수 배출이 용이한 가변형 가지관을 갖는 역세관에 관한 것이다. 더욱 상세하게는 이온교환수지를 이용한 순수제조설비, 복수탈염설비의 이온교환수지 재생탱크에서, 역세 공정 시 이온교환수지의 유출을 막고 역세수 배출이 용이하도록 하여 역세 효율을 개선시킬 수 있는 이온 교환 수지 재생 탱크에서 역세수 배출이 용이한 가변형 가지관을 갖는 역세관에 관한 것이다.The present invention relates to a backwashing pipe having a variable branch pipe that is easy to drain backwash water in an ion exchange resin regeneration tank. More specifically, in an ion exchange resin regeneration tank of a pure water manufacturing facility using a ion exchange resin or a multiple desalination plant, an ion exchange which can improve the backwashing efficiency by preventing the outflow of the ion exchange resin during the backwashing process and facilitating backwash water discharge The present invention relates to a backwashing pipe having a variable branch pipe that is easy to drain backwash water from a resin recycling tank.

재생 공정 중 역세 공정(逆洗 工程)이란 포화된 수지에 부착된 고형물질, 예를 들면 철산화물, 현탁부유물질 등을 제거하기 위해 재생탱크 하부에서 상부 방향으로 역세수를 통수(通水)시켜 역세수와 수지의 마찰작용에 의해 고형물질을 탈리시키는 공정을 말한다. 역세 후에 역세수는 많은 고형물질을 함유하게 되어 매우 탁한 상태로 불순물을 포함하게 되며, 재생탱크 상부의 역세관(Overflow line)을 통해서 재생탱크 외부로 배출되게 된다.The backwashing process during the regeneration process involves passing backwash water from the bottom of the regeneration tank upwards to remove solid substances, such as iron oxides and suspended solids, attached to the saturated resin. Refers to the process of removing solids by friction between backwash and resin. After backwashing, backwashing water contains a large amount of solid material and contains impurities in a very turbid state, and is discharged to the outside of the regeneration tank through an overflow line at the top of the regeneration tank.

종래의 역세수 배출용 역세관은 원통형 구조의 표면에 와이어 메쉬(Wire mesh)가 설치되어 수지의 유출을 막게 되어 있지만, 역세 중 수지에서 탈리되는 고 형물질과 파쇄된 수지가 와이어 메쉬의 공극(空隙) 을 막아 역세수 배출을 방해하는 현상을 초래한다. 이에 따라 역세수와 함께 고형물질이 재생탱크 외부로 배출되지 못하고, 메쉬에 계속 침착되어 역세수 소모량이 증가하거나 역세시간이 증가하여 역세효율이 저하되는 현상이 발생하고 있다. In the conventional backwash pipe for backwash water discharge, a wire mesh is installed on the surface of the cylindrical structure to prevent the outflow of the resin, but the solid material and the crushed resin detached from the resin during backwashing are voids of the wire mesh ( This prevents the air from leaking out and prevents backwash water discharge. Accordingly, the solid material is not discharged to the outside of the regeneration tank together with the backwash water, and is continuously deposited on the mesh to increase the backwash water consumption or the backwash time to increase the backwash efficiency.

즉, 종래의 와이어 메쉬 구조의 역세관은 잦은 막힘 현상의 발생으로 고형물질의 배출을 막아 역세 효율을 저하시키는 문제점이 있었다.That is, the conventional backwashing tube of the wire mesh structure has a problem of reducing the backwashing efficiency by preventing the discharge of solid materials due to frequent clogging.

이에 본 발명은 이온교환수지의 재생탱크의 상부까지 높이 역세수 유량, 고형물질의 부유정도에 따라 가지관의 높이를 탄력적으로 변경할 수 있는 높이 조절이 가능한 가변형 가지관을 갖는 이온 교환 수지 재생 탱크에서 역세수 배출이 용이한 역세관을 제공하는데 그 목적이 있다. Therefore, the present invention is the reverse in the ion exchange resin regeneration tank having a variable branch pipe height adjustable to elastically change the height of the branch pipe according to the height of the backwash flow rate, the degree of solid matter floating up to the top of the regeneration tank of the ion exchange resin The purpose is to provide a customs office that facilitates the discharge of tax revenues.

The backwashing pipe having a variable branch pipe that is easy to drain backwash water in the ion exchange resin regeneration tank of the present invention includes four to eight backwashing pipes that serve as induction pipes through which backwash water flows into the main building of the cylindrical backwashing pipe. It is characterized by being installed in the upper direction of the regeneration tank.

본 발명에 따르면, 상기 역세 가지관은 역세본관과 탱크 상부와의 높이에 따라 자유롭게 높이를 조절할 수 있도록 가변형 구조를 가지며, 본관과 가지관 또는 가지관과 가지관이 서로 나사형태로 연결할 수 있는 구조이므로 재생탱크의 형태 및 역세수의 유량에 따라 연결 및 분리가 가능한 구조를 갖는 것을 특징으로 한다.According to the present invention, the reverse three branch pipe has a variable structure so that the height can be freely adjusted according to the height of the reverse three main pipe and the upper tank, the main pipe and the branch pipe or the branch pipe and the branch pipe can be connected to each other in the form of a screw Therefore, it is characterized by having a structure that can be connected and separated according to the shape of the regeneration tank and the flow rate of the backwash water.
