A filtering device of a cooker hood is configured in a V shape with an upward opening as a whole, and includes a V-shaped inner surface and a V-shaped outer surface. A tube portion is embedded between the inner surface and the outer surface, both ends of the tube portion being closed. The tube portion has a V shape with an upward opening. The tube portion includes an air inlet and an air outlet disposed in an interleaved manner, with the air inlet being located on the outer surface, and the air outlet being located on the inner surface. In this way, a rotating airflow is suitable to be formed in the tube portion of the filtering device, thereby improving a grease separation effect.

An apparatus for remediation of a copper and nickel co-contaminated soil includes a housing. A crushing device is arranged at the upper part of the inside of the housing. A stirring device is arranged below the crushing device. An anode electrode and a cathode electrode are provided at both ends of the inner bottom of the housing, respectively. In the present invention, the soil contaminated by copper and nickel is first poured from the top of the crushing device, and then crushed thoroughly under the action of the crushing device. The crushed soil facilitates the movement of copper and nickel metal ions therein toward the electrodes under the action of the anode electrode and the cathode electrode, thereby achieving optimal soil remediation.

Apparatus for remediation of a copper and nickel co-contaminated soil and a method for using the same

It discloses a texturing method for a diamond wire cut polycrystalline silicon slice, including the following steps: firstly, immersing the diamond wire cut polycrystalline silicon slice into a mixed aqueous solution of an alkali solution and an alkali reaction control agent, removing a damaged layer on a surface of the silicon slice, and then immersing the silicon slice into a hydrofluoric acid solution containing inorganic ions and organic molecules for reaction; secondly, pretreating the polycrystalline silicon surface by a mixed solution of hydrofluoric acid and hydrogen peroxide, adding a pore-forming regulator at the same time, and finally texturing the surface of the silicon slice by a mixed acid solution of hydrofluoric acid and nitric acid.
