The utility model relates to the technical field of
flue gas detection, and provides a low-concentration automatic
smoke dust and
flue gas comprehensive tester which comprises a
flue gas comprehensive tester body, the inlet end of the
flue gas comprehensive tester body is fixedly connected with a gas guide
pipe, the inlet end of the gas guide
pipe is provided with a cooling mechanism, the inlet end of the cooling mechanism is provided with a
smoke inlet mechanism, and the inlet end of the
smoke inlet mechanism is provided with a smoke outlet mechanism. The smoke inlet mechanism comprises a mounting box, a smoke inlet
assembly is arranged at the inlet end of the mounting box, a smoke
exhaust pipe is fixedly connected to the outlet end of the mounting box, a filter screen is fixedly connected to the interior of the mounting box, a reciprocating lead screw is rotationally connected to one end of the inner side of the mounting box, a motor is fixedly mounted on the outer side of the mounting box, and an output shaft of the motor is fixedly connected with the reciprocating lead screw. The reciprocating lead screw is in threaded connection with a movable block, and a cleaning
assembly is arranged at one end of the movable block. According to the
flue gas comprehensive tester, dust in
flue gas is filtered through the filter screen, so that the dust can be prevented from entering the flue gas comprehensive tester body to pollute the flue gas comprehensive tester body, and the problem of difficulty in subsequent cleaning is avoided.
