Abstract: A pan-tilt-zoom device includes a housing, a carrier, an image sensor, and a shape memory alloy (SMA) motor. An accommodating cavity is formed in the housing, and a first opening in communication with the accommodating cavity is provided on the housing. The carrier is located in the accommodating cavity, the carrier has a lens mounting hole, and an opening at one end of the lens mounting hole faces the first opening. The image sensor is located in the accommodating cavity and is disposed on a side that is of the carrier and that is away from the first opening, and a photosensitive surface of the image sensor faces an opening at the other end of the lens mounting hole. The SMA motor is configured to drive the carrier to tilt in the accommodating cavity along with the image sensor in any direction around, to implement optical image stabilization.

Abstract: The present disclosure relates to a wastewater flue evaporating device. An wastewater evaporation crystallizer is provided, including an evaporating tube inlet, an inlet flange, an inlet chamber, a pneumatic inlet baffle, an evaporating tube body, a pneumatic outlet baffle, an outlet chamber, an outlet flange, and an evaporating tube outlet which are successively coupled, where the evaporating tube inlet is connected to provide a gas pipeline; the gas pipeline is connected on a flue between an external denitration device and an air preheater; the evaporating tube outlet is communicated with an inlet flue of a dust collector; the evaporating tube body is provided with a wastewater nozzle; and the wastewater nozzle is communicated with a pretreated waste pipe. The present disclosure provides an efficient and energy-saving wastewater evaporation crystallizer which increases evaporation efficiency by bringing in a high-temperature gas at a front end of the air preheater.
