Description

폐수 재처리 기반 열교환기 번들 자동 세척 장치Wastewater reprocessing-based heat exchanger bundle automatic cleaning device
본 발명은 폐수 재처리 기반 열교환기 번들 자동 세척 장치에 관한 것으로, 좀 더 구체적으로는 외부세척모듈과 내부세척모듈의 설정된 동작 패턴에 따라 열교환기의 외부 번들 및 내부 튜브를 자동 세척할 수 있으며, 열교환기 세척시 사용된 세척수를 재처리하여 세척수로 재사용할 수 있는 폐수 재처리 기반 열교환기 번들 자동 세척 장치에 관한 것이다.The present invention relates to an apparatus for automatically cleaning a heat exchanger bundle based on wastewater reprocessing, and more specifically, it is possible to automatically clean the outer bundle and inner tube of the heat exchanger according to the set operation pattern of the external cleaning module and the internal cleaning module, The present invention relates to an automatic washing apparatus for a heat exchanger bundle based on wastewater retreatment that can be reused as washing water by reprocessing washing water used when washing a heat exchanger.
열교환기는 발전소에서 터빈 윤활유 냉각기 내부를 순환하는 냉각수를 이용하여 터빈 윤활유의 온도를 떨어뜨리거나, 가정에서 사용하는 냉장고에서 음식이 상하지 않도록 저온으로 신선하게 보관할 수 있도록 응축기로 사용되기도 한다.The heat exchanger is also used as a condenser to reduce the temperature of the turbine lubricant by using cooling water circulating inside the turbine lubricant cooler in a power plant, or to keep food fresh at a low temperature so that food does not spoil in a refrigerator used at home.
이러한 열교환기를 세척하기 위하여 작업자가 수작업으로 압력 공기를 이용하여 세척수를 분사함으로써 번들과 튜브를 세척하거나, 공기분사식 세척기를 이용하여 세척작업을 수행하였다. 공기분사식 세척기는 세척제를 가득 채운 용기 안에 냉각기의 튜브를 넣고 공기방울을 발생시켜 공기방울과 세척제의 밀도차를 이용하여 세척제를 유동시킴으로써 열교환기의 튜브를 세척하는 장치이다.In order to clean such a heat exchanger, an operator manually sprays washing water using pressurized air to wash bundles and tubes, or performs a washing operation using an air injection type washer. An air jet washer is a device that cleans the tube of the heat exchanger by placing the tube of the cooler in a container filled with the cleaning agent, generating air bubbles, and flowing the cleaning agent using the difference in density between the air bubbles and the cleaning agent.
작업자가 수작업으로 열교환기의 튜브를 세척하는 경우에는 세척제 분사에 따른 미세먼지 발생으로 인하여 작업자가 세척작업을 하는데 어려움이 발생하였으며, 완전히 세척하는데 많은 시간이 소요되는 문제점이 있었다. When the operator manually cleans the tube of the heat exchanger, it is difficult for the operator to perform the washing operation due to the generation of fine dust due to the injection of the detergent, and there is a problem that it takes a lot of time to completely clean.
또한, 공기분사식 세척기를 통하여 열교환기를 세척하는 경우 용기안에 세척제를 가득 채워야 하며, 공기방울 발생에 따른 세척제의 증발로 용기 안에 추가로 세척제를 주입하여야 했기 때문에 세척제가 너무 많이 소모되는 문제점이 있었다. 그리고 공기방울이 발생되어 세척제가 유동되는 부위만 세척되기 때문에 균일하게 세척되지 못하였다.In addition, when cleaning the heat exchanger through an air-jet type washing machine, the container must be filled with detergent, and because the detergent must be additionally injected into the container due to evaporation of the detergent due to the occurrence of air bubbles, there is a problem that too much detergent is consumed. In addition, since air bubbles are generated and only the part where the cleaning agent flows is washed, it was not uniformly cleaned.
이러한 문제점을 해결하기 위하여 대한민국등록실용신안공보 제20-0476774호에 냉각기의 튜브 번들 세척기가 게시되어 있으나, 열교환기 튜브를 회전시킬 수 있도록 양단에 회전장치가 고정된 상태로 갖추어져 설정된 크기의 열교환기 제품만을 세척할 수 있는 문제점이 있었다. 또한, 열교환기의 각각의 튜브를 선택적으로 정밀하게 세척할 수 없어 많은 양의 세척수를 소모하게 되는 문제점이 있었다.In order to solve this problem, Korean Utility Model Publication No. 20-0476774 discloses a tube bundle washing machine for a cooler, but a heat exchanger of a set size is equipped with rotating devices fixed at both ends to rotate the heat exchanger tube. There was a problem that only the product could be washed. In addition, there is a problem in that a large amount of washing water is consumed because each tube of the heat exchanger cannot be selectively and precisely cleaned.
따라서 본 발명은 이와 같은 종래 기술의 문제점을 개선하여, 외부세척모듈과 내부세척모듈의 설정된 동작 패턴에 따라 열교환기의 외부 번들 및 내부 튜브를 제어기에 자동 세척할 수 있는 폐수 재처리 기반 열교환기 번들 자동 세척 장치를 제공하는 것을 목적으로 한다.Accordingly, the present invention improves the problems of the prior art, and is a wastewater reprocessing-based heat exchanger bundle capable of automatically washing the outer bundle and inner tube of the heat exchanger in the controller according to the set operation pattern of the outer washing module and the inner washing module. It is an object to provide an automatic cleaning device.
또한, 열교환기의 길이에 관계없이 열교환기 번들의 하부를 지지하는 간격을 조절하는 동시에 열교환기 번들을 회전시킬 수 있는 폐수 재처리 기반 열교환기 번들 자동 세척 장치를 제공하는 것을 목적으로 한다. In addition, an object of the present invention is to provide an apparatus for automatically cleaning a heat exchanger bundle based on wastewater reprocessing capable of rotating a heat exchanger bundle while adjusting an interval for supporting a lower portion of a heat exchanger bundle regardless of the length of the heat exchanger.
또한, 열교환기 튜브의 위치를 자동 인식하여 내부세척모듈의 노즐피더가 튜브의 정확한 위치에 삽입 또는 후퇴되는 폐수 재처리 기반 열교환기 번들 자동 세척 장치를 제공하는 것을 목적으로 한다. In addition, an object of the present invention is to provide an automatic washing apparatus for a heat exchanger bundle based on wastewater reprocessing in which a nozzle feeder of an internal washing module is inserted or retracted at an exact position of the tube by automatically recognizing the position of the heat exchanger tube.
또한, 열교환기 세척시 사용된 세척수를 재처리하여 세척수로 재사용할 수 있는 폐수 재처리 기반 열교환기 번들 자동 세척 장치를 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide an automatic washing apparatus for a heat exchanger bundle based on wastewater retreatment that can be reused as washing water by reprocessing washing water used for washing a heat exchanger.
