Description
Technical Field
The invention belongs to the technical field related to glass fiber reinforced plastics, and particularly relates to an air pipe joint and a construction method.
Background
Fermentors are commonly used industrially for carrying out microbial fermentations. The main body is a main cylinder made of food-grade FRP composite material, and the volume of the main cylinder is 1m3To several hundred m3. The structure of the fermentation tank for anaerobic fermentation (such as alcohol and solvent production) can be simpler. ForFermentation tanks for aerobic fermentation (e.g. for the production of antibiotics, amino acids, organic acids, vitamins, etc.) are relatively complex in structure due to the need to continuously introduce large amounts of sterile air into the tank and the availability of the introduced air, and are commonly used in mechanical agitation type fermentation tanks, bubbling type fermentation tanks, and lift type fermentation tanks.
When the fermentation tank is filled with sterile air, strong vibration can be generated between the stainless steel air connecting pipe and the glass fiber reinforced plastic fermentation tank, the conventional connection mode between the air connecting pipe and the fermentation tank cannot meet the fixation between the stainless steel and the glass fiber reinforced plastic, the air connecting pipe is easily separated from the fermentation tank, and therefore the stainless steel and the glass fiber reinforced plastic can be well fixed together by matching a reasonable fixing structure with a special construction process.
