Definitions

  • the invention relates to methods for protecting metallic components from Corrosion in drying systems such as drying chambers, duct dryers, Autoclaves and the like in the building materials industry.
  • the task is accomplished through a process to protect metallic components against corrosion in drying systems in the building materials industry with the characterizing features of claim 1 solved.
  • the direct supply of the steam-volatile is of great advantage Inhibitors in the channels and / or directly in the hot air or steam flow according to claim 2.
  • the inhibitors mix with the Drying media, and get as a mixture in the Drying chambers or autoclaves, where they can be used with steam or hot air on the metal surfaces form.
  • the inhibitors can on the one hand with the expelled mixing water or the steam for heating the Distribute building materials.
  • the dosage of the inhibitors has an effect in the form of aliphatic amines according to claims 4 and 5 improving quality on building materials such as clay, limestone or aerated concrete out. They show a cheaper interfacial activity, a better one Drying behavior and have a lower sensitivity to cracks
  • the method according to the invention is characterized by a easy-to-handle corrosion protection made of substantial material and repair cost savings, longer life of the metallic plant parts as well as minimizing the through System downtimes result in production downtimes.
  • the more cost-effective production of the systems by eliminating the previous ones costly corrosion protection measures is another positive consequence of the method according to the invention.
  • the incoming air is with a Burner 4 heated.
  • preference is given directly to the air duct 2 sprayed through a metering lance 5 aliphatic amine, which in a container 8 prepared aliphatic amine via a Connection line 7 and, for example, a menbral piston pump 6 the metering lance 5 is supplied.
  • a concentration aliphatic amines in the aqueous phase of the air flow from 0.1 to 150 mg / kg specified.
  • the one enriched with the aliphatic amine and heated air flow is passed into a drying chamber 3 in which for example, moist bricks are stored for drying.
  • the heated one Air flow drives the water out of the bricks.
  • the aliphatic amines are over the enriched with the expelled water Hot air flow in the drying chamber 3 and the following in the Drawing not described system parts evenly and finely distributed and form a on the metallic surfaces corrosion-resistant layer.
