The invention discloses an intelligent flue gas purification device for environmental protection, which relates to the field of flue gas purification. Aiming at the fact that the existing flue gas contains a large amount of mist oil, an oil film will be formed in a short time when passing through the filter element, resulting in The problem that the filter element loses its filtering and purification effect is now proposed as follows, including the device housing, flue gas inlet, purification outlet, activated carbon filter element, and induced draft fan, the motor output shaft of the induced draft fan is equipped with a conical heart gear A transmission mechanism is installed on one side of the conical heart gear in the housing of the device; the inner wall of the housing of the device rotates along its length direction and is equipped with a transmission rod two, and the transmission rod two is arranged near one end of the induced draft fan There are regulatory agencies. The cutting device of the present invention moves along the radial direction of the activated carbon filter element while rotating, thereby cutting the surface of the entire activated carbon filter element, cutting off the thin layer forming the oil film, ensuring its filtering and purification effect, and meanwhile the activated carbon filter element is fully utilized.

The invention discloses a purification device applied to floor wastewater treatment and belongs to the field of floor wastewater purification devices. The purification device applied to the floor wastewater treatment comprises a wastewater collection pipe and a pure water main pipe, wherein the wastewater collection pipe is connected with a flow meter; the pure water main pipe penetrates through an upper-floor house and a lower-floor house; the upper end of the wastewater collection pipe is located in the upper-floor house. According to the purification device disclosed by the invention, impurities in wastewater can be primarily removed by utilizing a purification pipe through a filter screen filtering layer and an active carbon adsorption layer; meanwhile, a filtered water flow further permeates a circular truncated cone type RO (Reverse Osmosis) membrane; a hollow fiber membrane is used for removing bacteria and the water flow is clarified, so that the wastewater is purified and the purified wastewater is discharged into the pure water main pipe; meanwhile, quantitative pure water is stored from the pure water main pipe through a water storage tank; the filter screen filtering layer and the active carbon adsorption layer, which are overturned, are subjected to backwashing by utilizing pure water and the circular truncated cone type RO membrane and the hollow fiber membrane are washed, so that pollution to a sewer is effectively avoided and the environment is protected.

The invention discloses an air purifier which comprises a purifier body and a barrel-shaped filter element, wherein the purifier body is provided with an air purification cavity for containing the filter element; furthermore, the air purifier further comprises a filter element mounting and fixing device which is arranged in the air purification cavity and is used for mounting and fixing the filter element; the filter element mounting and fixing device consists of a lifting disk fixing frame, a lifting disk, a knob and a base which are connected in sequence from top to bottom; a hole from which the lifting disk extends out is formed in the lifting disk fixing frame; the knob is arranged on the base in a rotatable manner; the upper end of the knob supports the lifting disk and drives the lifting disk to do reciprocating movement in the direction perpendicular to the base; and therefore, the filter element is easy to dismount and mount; meanwhile, damage to the filter element filter element dismounting and mounting processes can be avoided; the filter purification effect is guaranteed.
