An anti-icing device for dry fog and dust suppression nozzles, which belongs to the field of fluid application technology, is characterized in that it fills the entire liquid circuit system with an antifreeze cleaning liquid composed of emulsified silicone oil and water at a ratio of 0.05%-5%. , and sprayed from the nozzle, the water molecules and air dissociated in the entire liquid circuit system are discharged or fused into the antifreeze cleaning liquid, the entire liquid circuit system and the dry fog dust removal nozzle will not freeze, and the water hole is always maintained Unobstructed device, the application of this device effectively solves the problem that the dry fog dust suppression nozzle cannot work normally due to freezing. In this way, the occurrence of vicious incidents caused by the loss of control of the nozzle icing liquid path can be avoided, and the whole process can be easily automated without causing secondary pollution to the environment, which brings great convenience for the maintenance of the dry fog and dust suppression system.

The invention discloses a metal nozzle anticorrosion device, belongs to the technical field of metal corrosion prevention, and is characterized in that cationic polyacrylamide PAM is made into a 0.1%-0.30% aqueous solution as a first cleaning liquid; Lonza polyaminopropyl biguanide is added to the first cleaning liquid to prepare a 10%-21% aqueous solution as a second cleaning liquid; a glycerol emulsion is added into the second cleaning liquid to prepare a 0.05%-5% aqueous solution as a third cleaning liquid, a whole liquid path system is filled with the third cleaning liquid gradually, the third cleaning liquid is sprayed out from a nozzle, and water molecules and air free in a whole liquid path system are discharged out or fused into an anti-corrosion cleaning liquid; a layer of anti-corrosion cleaning liquid thin film is formed at a contact part of the metal nozzle with the liquid, so that the nozzle and water through holes of the nozzle cannot form electrochemical corrosion conditions. The corrosion prevention of the metal nozzle and the corrosion prevention of the water through holes of the nozzle are achieved, the water through holes of the metal nozzle still keep unobstructed, and thus the problem that a dry fog dust suppression metal nozzle cannot work normally due to corrosion is solved.

The invention provides an air conditioner linkage control method, an air conditioner linkage control device and an air conditioning unit, and relates to the air conditioning technology field. The airconditioner linkage control method includes: collecting environment parameters of space where the air conditioning unit is located according to a preset time period; and when judging that a predefinedearly warning incident occurs based on the collected environment parameters, sending the early warning incident to a second air conditioner in the air conditioning unit so as to enable the second airconditioner to select a matched early warning mode for warning output according to the early warning incident. The air conditioner linkage control method realizes linkage early warning among a plurality of air conditioners, does not need to use a third-party device for transferring early warning information, thereby timely reminding a user of the early warning incident occurring indoors, and facilitating timely decision making and disposal for the user.
