An anti-corrosion device for metal nozzles

Abstract

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.

Description

technical field [0001] The present invention is a metal nozzle anti-corrosion device and application method, which belongs to the technical field of metal anti-corrosion, specifically a kind of cationic polyacrylamide PAM will be prepared as the No. 1 cleaning solution in the aqueous solution of 0.1% ~ 0.30%, adding Lonza polyaminopropyl biguanide is prepared into a 10%--21% aqueous solution as the No. 2 cleaning solution, and the glycerin emulsion is added to prepare a 0.05%--5% aqueous solution as the No. 3 cleaning solution. And it is sprayed from the nozzle, so that the water molecules and air dissociated in the entire liquid system are discharged or fused into the anti-corrosion cleaning liquid, and a layer of anti-corrosion cleaning liquid film is formed on the contact part between the metal nozzle and the liquid, so that the nozzle and the nozzle communicate The water hole cannot form electrochemical corrosion conditions, and realizes the anti-corrosion of the metal noz...

Problems solved by technology

[0003] The purpose of an anti-corrosion device for metal nozzles of the present invention is to solve the existing and unsolvable problems in the above-mentioned prior art, thereby disclosing a simple and reliable anti-corrosion cleaning liquid composed of silicone oil emulsified and water mixed in proportion. The anti-corrosion cleaning liquid is filled into the entire liquid circuit system and sprayed from the nozzle, so that the anti-corrosion cleaning liquid makes the water molecules and air dissociated in the entire liquid circuit system discharge or merge into the antifreeze cleaning liquid. A layer of anti-corrosion cleaning liquid film is formed on the liquid contact part, so that the nozzle and the nozzle water hole cannot form electrochemical corrosion conditions, and the anti-corrosion of the metal nozzle and the corrosion resistance of the metal nozzle water hole are realized. The metal nozzle water hole is always Keep the unobstructed state, start the gas path valve and liquid path valve, it can be realized, the normal gas mist dust suppression work, the technical feature of the device is that the anti-corrosion cleaning liquid in the anti-corrosion device of the additional dry fog dust suppression metal nozzle flows through the outdoor The liquid circuit system flows out from the nozzle, so that the anti-corrosion cleaning liquid makes the water molecules and air dissociated in the entire liquid circuit system discharge or merge into the anti-corrosion cleaning liquid, forming a layer of anti-corrosion cleaning on the contact part of the metal nozzle and the liquid In this way, the nozzle and the nozzle water hole cannot form electrochemical corrosion conditions, and the corrosion resistance of the metal nozzle and the metal nozzle water hole are realized. The metal nozzle water hole is kept unobstructed, so that the spraying When the system suspends the spraying work, the nozzle and nozzle water hole are protected from corrosion, which is a bottleneck in the industry, so as to avoid the occurrence of vicious incidents caused by nozzle corrosion failure and liquid circuit out of control
