Detailed ways

In order to make it easy to understand the technical means, creative features, objectives and effects of the present utility model, the present utility model will be further elaborated below in conjunction with specific implementation modes.

As shown in Figures 1 to 4, a dust removal device for environmental engineering includes a casing 1, a fan 2 and a water storage tank 3. The fan 2 is placed at the air inlet of the casing 1, and the water storage tank 3 is installed on the machine. The upper end of the shell 1 and the lower end of the water storage tank 3 are provided with a rotating water spray head 4; the inner end of the fan 2 is connected to an air inlet duct 6, and the other end of the air inlet duct 6 is provided with a protective cover 5. The upper end of the air inlet duct 6 A connection frame 7 is provided at the opening, and the rotating water spray head 4 is inserted into the connection frame 7. The lower end of the connection frame 7 is connected to a curved filter 8, and the curved cover of the curved filter 8 covers the mouth of the air inlet pipe 6. , the lower end of the protective cover 5 is provided with an inclined pipe 9, the lower end of the inclined pipe 9 is provided with a first drainage pipe 10 and an air outlet pipe 12, and a second drainage pipe 11 is provided at the connection between the air outlet pipe 12 and the inclined pipe 9 for drainage. When in use, the fan 2 is started to allow the air around the equipment to enter. The fan 2 will enter the air containing particulate matter into the protective cover 5. The air containing particulate matter needs to pass through the curved filter 8. The curved filter 8 realizes particulate filtration of the air containing particulate matter. , the filtered air is then exhausted through the air outlet duct 12. When cleaning the filter, the water storage tank 3 rotates the water spray head 4 to spray water, and aims at the curved filter 8 to spray water to clean it. The particulate matter then falls, and then the fan 2 is used to drive the curved filter screen 8 to shake, speeding up the falling rate of the particulate matter on the curved filter screen 8, making the cleaning more complete; the inclined pipe 9, the first drain pipe 10, the second The drainage pipe 11 and the air outlet pipe 12 are designed in one piece, the inclined pipe 9 is welded and fixed to the protective cover 5, the protective cover 5 is bolted to the connection frame 7, the air inlet pipe 6 and the protective cover 5 are designed in one piece; the arc filter 8 is connected with The frame 7 is fixed with bolts, and the cross-section of the inner hole connecting the frame 7 is designed as an inverted trapezoid; the rotating water spray head 4 rotates to spray water onto the curved filter screen 8; during drainage, sewage with particulate matter enters the inclined pipe 9, and the sewage passes through The inclined pipe 9 slides down to the first drainage pipe 10 and is discharged from the first drainage pipe 10.
