Detailed ways

The utility model will be further described below in conjunction with the embodiment shown in the accompanying drawings.

Embodiment 1: Refer to the accompanying drawing 1. An integrated external compact movable multi-layer organic waste gas high-efficiency biological filter, which includes a scrubber 1 and a biological filter 2 connected in series.

The scrubber 1 includes a reactor 3 and a multistage self-rotating centrifugal device arranged in the reactor 3 . The bottom of the reactor 3 has a first gas inlet 4 and a water outlet 5 , and the top of the reactor 3 has a water inlet 6 and a first gas outlet 7 . The first air inlet 4 is connected to the exhaust gas source, the first air outlet 7 is connected to the biological filter 2 , and the first air inlet 4 is provided with a valve 41 .

The multi-stage self-rotating centrifugal device is arranged between the water inlet 6 and the water outlet 5 . The multi-stage self-rotating centrifugal device includes a shaft 9 vertically arranged in the reactor 3, a motor 10 for driving the shaft 9 to rotate, a plurality of centrifugal turntables 11 arranged on the shaft 9 and rotating coaxially with the shaft 9, and a plurality of centrifugal turntables 11 arranged on the centrifugal turntable 11 12 above the funnel. The centrifugal turntable 11 has an upper surface, which is a slope inclined downward. The funnel 12 has a through hole, which is surrounded by a truncated conical inclined surface. The edge of the funnel 12 is connected to the inner wall of the reactor 3, and the through hole is opposite to the centrifugal turntable 11 arranged below it. The water inlet 6 is provided with a rotor 8 which is fixedly connected to the shaft 9 and rotates with the shaft 9 .
