The selection of glass lined reactor head needs to be determined according to the model, with different specifications and sizes. So how do you determine the size of glass lined reactor head?
Generally, the glass lined reactor head adopts standard elliptical head, and the wall thickness of the head is generally the same as that of the cylinder. Under the special production process requirements of users, the head type of glass lined reactor can also adopt flanged folded spherical head, folded spherical head, tapered head with folded edge and flat cover head.
The non folded spherical head is suitable for vessels with diameter DN less than or equal to 8000mm. Because the diameter is too large, it is easy to warp and deform during enameling. The flat cover is generally used for dn<500mm. In order to prevent burning out deformation, its wall thickness should be thicker than other types of heads. The head of general glass lined reaction kettle shall be removable to facilitate the maintenance and repair of equipment. When the head is removable, its diameter shall be greater than 1200mm, generally 300mm × 400mm long round manhole.
If the head cannot be disassembled, its hole diameter shall be greater than or equal to 600mm. Of course, if there is a stirrer in the enamel reactor, the manhole size should also be determined according to the diameter of the stirrer and other factors.
