The present invention relates to a scrubber having a removable liquid injection pipe for removing harmful gases (NOx) and odors, and more specifically, to solve the problem of cleaning or replacing the injection pipe of the liquid injection pipe during the operation of the scrubber system. In order to solve the problem, it relates to a technology that improves the coupling method and structure of the injection pipe. The present invention for this purpose is an absorption tower partitioned into a plurality of spaces by a plurality of filler layers, a liquid injection device installed on the upper side of the space, and a cleaning device for removing harmful gases and odors with the liquid injection device. A scrubber comprising a pipe for supplying a liquid and a cleaning liquid recovery unit for recovering the cleaning liquid, wherein the liquid injection device comprises an injection pipe for injecting liquid and an injection pipe support for supporting the injection pipe, The pipe is a scrubber characterized in that it is detachable from the injection pipe support. In the present invention through the above configuration, it is possible to clean the injection pipe of the scrubber system without frequent interruption of operation of the scrubber system, so that it can be operated 24/7, and the operator can be safely protected from harmful gases. In addition, the efficiency of the filler layer can be promoted by increasing the spraying efficiency through the composition of the spray pipe and the mesh network, and the overall system size is reduced while maintaining the reduction efficiency of pollutants by increasing the overall efficiency of the system. There is an effect that can be maintained more continuously.본 발명은 유해가스(NOx) 및 악취 제거용 착탈 가능한 액체 분사관을 갖는 스크러버에 관한 것으로, 보다 구체적으로는 스크러버 시스템의 작동과정에서 액체 분사관의 분사관이 막힐 때에 이의 청소 내지 교환의 문제점을 해결하기 위하여 분사관의 결합방식과 구조를 개선한 기술에 관한 것이다. 이를 위한 본 발명은 내부가 다수개의 충전재층에 의해 다수개의 공간으로 구획되는 흡수탑과, 상기 공간부 상측에 설치되는 액체 분사장치와, 상기 액체 분사장치로 유해가스 및
