The invention belongs to the technical field of machining, and discloses a piston, a piston manufacturing device and a piston manufacturing method. The piston includes: a piston base; a porous functional layer, which is arranged on the top surface of the piston base; a microporous filling layer, which is arranged on the top surface of the porous functional layer, and the hole diameter in the micropore filling layer is smaller than that in the porous functional layer. The diameter of the hole; the sealing layer, which is arranged on the top surface of the micropore filling layer, is used to block the holes in the micropore filling layer. While the microporous filling layer of the piston plays the role of transition between the porous functional layer and the sealing layer, the microporous filling layer plays a role of filling the porous functional layer to a certain extent. The sealing layer acts as a plug to prevent the corrosive medium from entering the pores of the porous functional layer and the microporous filling layer to corrode them, thereby improving the corrosion resistance of the piston. In addition, air can be filled in the pores of the porous functional layer and the micropore filling layer, which effectively reduces the volume specific heat capacity of the coating.

The invention discloses a processing method for incinerating toxic waste liquid by smoke concentration and gasification. The processing method comprises the following steps of: firstly, preprocessing a high-calorific value waste organic solvent and low-calorific value toxic waste liquid in the toxic waste liquid; delivering the high-calorific value waste organic solvent in an incinerator for burning through a waste organic solvent burner to generate high-temperature flue gas, concentrating the low-calorific value toxic waste liquid in the toxic waste liquid with the generated high-temperatureflue gas to form steam and concentrated high-temperature low-calorific value toxic waste liquid; and conveying the concentrated high-temperature low-calorific value toxic waste liquid subjected to gasification into the incinerator through a gas burner and burning together with the high-calorific value waste organic solvent. In the processing method, the burning temperature of the incinerator can be controlled more accurately to inhibit the generation of NOx. In the process of processing the low-calorific value toxic waste liquid, the waste heat of the incinerator is reasonably utilized by stages, the splat-cooling effect on the exhausted high-temperature flue gas is achieved at the same time, and the regeneration of toxic substances is inhibited. The invention also discloses a processing device used for the processing method.
