This invention provides a heat exchange device for waste heat utilization and cold-end corrosion prevention, comprising an air inlet box, a heat exchange box, a negative pressure device, an air outlet main pipe, a hot air return pipe, and several heat exchange units. The heat exchange box has a waste heat channel. Each heat exchange unit has two ends connected to the air inlet box and the input end of the negative pressure device, respectively, and each heat exchange unit extends through the waste heat channel. The negative pressure device is connected to the air outlet main pipe. The air outlet main pipe is also connected to one end of the hot air return pipe. The other end of the hot air return pipe extends into the waste heat channel, then extends out from the waste heat channel and connects to the air inlet box, thereby returning a portion of the high-temperature air after heat exchange to the air inlet box. This heat exchange device can increase the air temperature drawn into the heat exchange units, preventing the formation of a corrosive ash layer at the cold end of the heat exchange units due to excessively low temperatures, completely solving the technical problem of corrosive ash accumulation inside the device, extending the service life of the heat exchange device, and saving maintenance and repair costs.

The aircraft disclosed by the application can reduce the launch mass and cost of the aircraft, and the cluster control method can reduce the vulnerability of the aircraft system.

This utility model relates to the field of fermented soybean paste processing technology, specifically a drying yard with a dust-proof structure, including a preparation area component, and a drying area component installed on the right side of the preparation area component. The improved drying yard has a light-transmitting film on the outer walls of the first support frame, the first crossbeam, the second support frame, and the second crossbeam, allowing the drying yard to be enclosed without blocking sunlight. The shading cloth is adjusted using pulleys, belts, and fixing blocks, and the indoor temperature is regulated by installed ventilation fans and dust filters, reducing temperature fluctuations and preventing the entry of dust, flying insects, and other contaminants. Furthermore, changing cabinets are provided to reduce the amount of external contaminants brought in by workers, further reducing hygiene hazards during the sauce production process and lowering food safety risks. At the same time, the enclosed drying yard is less affected by weather conditions, enabling large-scale production, improving production efficiency, preventing excessive moisture evaporation, and ensuring more uniform fermentation of the sauce.

The stabilizer comprises a main body, a microphone module and a light supplement lamp module, the main body comprises an adjusting mechanism and a handheld part, the adjusting mechanism is rotatably connected with the handheld part, a fixing assembly is arranged on the adjusting mechanism, and the fixing assembly is used for fixing a shooting device; the microphone module is arranged in the adjusting mechanism, the light supplement lamp module is arranged on the adjusting mechanism, and the lens of the shooting device, the sound receiving opening of the microphone module and the light emitting surface of the light supplement lamp module are consistent in direction.
