Utility Model Content

[0005] The purpose of the utility model is to provide a ship boiler exhaust gas treatment device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A ship boiler exhaust gas treatment device comprises a treatment box; a support frame is fixedly connected to the bottom of the treatment box, an exhaust box is fixedly connected to the top of the treatment box, an air intake pipe is fixedly installed on one side of the treatment box near the bottom, a pair of spray racks are fixedly connected to both ends of the inner wall of the treatment box, connecting pipes are fixedly installed at both ends of the treatment box, each connecting pipe is respectively communicated with the outer end of each spray rack, a controller is fixedly installed at one end of the treatment box, and the controller is located on the other side of the connecting pipe at one end of the treatment box, a movable frame is slidably arranged inside the treatment box on the top of each spray rack, a connecting block is fixedly installed at one end of the movable frame, a screw rod is rotatably connected to one end of the treatment box through a bearing, and the screw rod is connected to the internal thread of the connecting block, a motor is fixedly installed on one side of the treatment box, and the output shaft of the motor is fixedly connected to one side of the screw rod, a filter screen is slidably installed inside the treatment box on the top of the movable frame through a plurality of second springs, a scraping component for cleaning the filter screen is arranged between the movable frame and the filter screen, an activated carbon screen is arranged inside the treatment box on the top of the filter screen, and a mounting component for installing and removing the activated carbon screen is arranged on one side of the treatment box.
