Glass-lined reactors are composed of multiple components, each of which plays a vital role. Operators must understand these parts before using them, so as to avoid equipment failure. The manhole device is one of its more important components, which can avoid equipment failure and damage.
The manhole of the glass-lined reactor is a necessary hole with a glass-lined cover. Generally, it is on the tank cover of the reactor. The staff can enter the reactor through the reactor manhole device for debugging, overhaul and maintenance. , cleaning, etc.
The glass-lined reactor manhole is generally installed on the top of the storage tank. The safety emergency ventilation device is usually used in conjunction with the fire extinguisher and mechanical breathing valve, which can not only avoid the sudden overpressure or vacuum in the tank due to unexpected reasons, damage the storage tank In the event of an accident, it also plays the role of safety and fire resistance. It is a safety device to protect the storage tank. It is especially suitable for the vaulted atmospheric tank whose storage material is capped with nitrogen. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safety and reliability.
Glass-lined reactor manholes are divided into emergency pressure relief manholes, explosion-proof fire-resistance breathing manholes, tank top manholes, tank wall manholes and core manholes. The diameter of the manhole of the glass-lined equipment is usually 600mm, which is convenient for the staff to enter and exit the oil tank and ventilation during installation, cleaning and maintenance. There are sealing rings on the flange and cover plate, and special attention should be paid to protection during construction. 3mm thick asbestos rubber gasket is used for sealing, no cracking is allowed. When installing the tightening bolts on the manhole cover, apply force in pairs to prevent the hole cover from being deformed.
