For example, in an LNG (liquefied natural gas) natural gas vaporization station, LNG is heat exchanged with air through an air temperature vaporizer, so that LNG is vaporized into gaseous natural gas, and the gaseous natural gas is supplied to different users under pressure regulation. However, in the process of heat exchange of LNG, the air-temperature vaporizer adsorbs moisture in the air, and when the amount of vaporization of the air-temperature vaporizer is large, a large amount of mist is formed, and the generated mist is heavier than the air, and thus the mist is spread while adhering to the ground. Thereby affecting the line of sight within the LNG vaporization station. Inconvenience is brought to inspection personnel, maintenance operation and dangerous goods transport vehicle sight in the station, certain potential safety hazards are caused, and safety production management work is seriously influenced. In addition, because the environment in the station is influenced by lower fog temperature and higher humidity, the health and the joint of workers in the station are not good, and the EHS management and control of enterprises are influenced to a certain extent.

For another example, in some project production workshops of heating power companies, thermal power plants, distributed energy resources and the like, once steam leakage occurs in a pressure container, the pressure container is easy to affect the view of the emergency repair environment, the emergency repair operation is affected, and potential safety hazards occur. If the ventilation pipeline is designed by considering the maximum leakage amount in the design stage, the investment cost is high.

For another example, a dust workshop generates a large amount of fine PM2.5 dust particles in the production process, at present, most of the fine PM2.5 dust particles are filtered by a mesh filter or spray water, the filter needs to be frequently replaced when the filter is used for dedusting, the spray water is high in dedusting water consumption, and the running cost of the two modes is high.

The air supply fan sucks the fog into the fog moving pipe, and the fog is discharged into the water of the water tray through the moving pipe and dissolved in the water to realize demisting.

When the low-temperature fog is removed, the low-temperature fog needs to be sucked into the transport pipe through the air supply fan, the fan blades of the air supply fan can adsorb the low-temperature fog when running at high speed, and a large amount of low-temperature fog is adhered to form ice, so that the fog cannot be normally sent into the water tray; simultaneously, easily cause the air supply fan to damage, can't guarantee that the defogging device moves for a long time.

The hose 7 plays the effects of shock absorption, noise elimination and noise reduction, and prevents the pipeline from cracking.

A water circulation system communicated with a water storage tank of the box body 1 is arranged outside the box body 1. The water circulation system includes a reservoir 51, a water inlet pipe 52, a water discharge pipe 53, and a water supply power source. For example, the water storage container 51 is an open water tank, the water supply source is a submersible pump 54, and the water supply source may be a pipe pump. Two ends of the water inlet pipe 52 are respectively communicated with the water storage cavity and the water tank, and two ends of the water outlet pipe 53 are respectively communicated with the water storage cavity and the water tank; a submersible pump 54 is disposed at the bottom of the tank and communicates with the inlet pipe 52.
