The invention discloses an ecological floating island for the restoration and treatment of black and odorous water bodies, which includes a floating seat, a mesh cylinder seat, a floating ball, a balance frame, a steel wire rope and fixed rivets, the bottom of the purification seat is welded with a mesh cylinder seat, and A floating seat is fixed on the outer wall of the clean seat at the junction of the clean seat and the net-shaped cylinder seat, and one end of the drive motor shaft is installed inside the raised top of the clean seat and extends to the bottom of the net-shaped cylinder seat and a turret is installed. A balance frame is installed at the bottom of the turret, a steel wire rope is connected to the center of the bottom of the balance frame, and a fixed rivet is fixed at one end of the steel wire rope. The present invention can effectively adjust the black and odorous water body through the rhizome of aquatic plants by installing the floating seat, the purification seat, the floating ball and the ecological planting tank, and can effectively collect the floating matter on the surface of the water body through the floating island to increase the area of ​​the purified water area and solve the problem of Traditional sewage purification devices have problems such as single purification function, small purification area, long treatment time, slow purification rate, and high maintenance cost.

The embodiment of the invention provides a smoke purification equipment and a system thereof, belonging to the field of smoke purification treatment. The smoke purification equipment comprises a tank body, an air inlet, an air exhaust, an inlet air pre-filtering apparatus, a combined type filtering apparatus, a centrifugal fan, a shock-absorption sealing apparatus, a wind chamber, a clapboard andan air discharge chamber; the air inlet is arranged on the tank body and communicated with the combined type filtering apparatus inside the tank body through the inlet air pre-filtering apparatus; anair outlet end of the combined type filtering apparatus is provided with a fan; the centrifugal fan is fixedly arranged inside the tank body through the shock-absorption sealing apparatus; an air inlet of the centrifugal fan is communicated with an air outlet of the combined type filtering apparatus; an air outlet of the centrifugal fan is communicated with the wind chamber inside the tank body; the clapboard is arranged at one side of the wind chamber so as to lead the interior of the tank body to form the air discharge chamber; the wind chamber is communicated with the air discharge chamberthrough an air hole on the clapboard; and the air exhaust is arranged on the air discharge chamber. The smoke purification equipment is simple in structure, can treat smoke gas generated in welding ofelectronic and machinery industries, and has advantages of large filtering flow, high efficiency, good filtering effects and low noise.

The invention discloses an indoor ventilation and air purifying circulating system. The system is characterized in that an air purifier and an air cylinder are controlled by a controller to externallydischarge air flow for a certain period of time every time when the system is started to conveniently blow dust in the air purifier and air cylinder outdoors, dust in the equipment is prevented fromentering indoors, indoor air quality is improved, and the problem that dust enters indoors is relieved. When air is discharged outwards, blades can be driven to rotate by the air flow, dust shaking balls at the ends of the blades can be touched to allow internal filter nets to shake and deform to achieve the dust removing on inner layer filter nets, dust on the inner layer filter nets can be effectively removed to improve the dust removing effect of the equipment and prevent dust from attaching to the filter nets, when the air flow is controlled to internally discharged by the controller, rotation preventing elastic nets can be prevented from bending in the direction towards the blades by the air flow, the shielding of the blades is achieved, the rotation of the blades is prevented, the dust on the filter nets can be prevented from being shaken indoors when the air flow is circulated indoors, and therefore the ventilation purifying effect is ensured.
