 What is the role of detachable double flange loose joint?
The ammonium sulfate solution produced by desulfurization contains tar, fly ash suspension and other impurities that easily affect product quality. Influenced by factors such as the raw material process, the water quality characteristics of ammonium sulfate will change, and it is impossible to control the crystalline particles, while the PH value will also affect the solubility of ammonium sulfate, mesostasis zone on crystal production. Detachable double flange loose sleeve transfer joint process is widely used in the process of raw material extraction, through high temperature evaporation of substances from the liquid or gaseous state evaporation to form crystals.
 
The principle of detachable double flange loose joint process is that the original liquid and steam evaporation reaction in a vacuum environment, with the increasing concentration of the original liquid, the original solution equilibrium is broken, the supersaturated state began to precipitate ammonium sulfate crystals, and then the nucleus as the center of the growing particles of larger crystals into the folded flow area after settling to the bottom was pumped out, smaller crystals continue to stay in the equipment crystallization. When the chloride ion in the water is too high, it is corrosive, which will reduce the durability of the metal pipeline, reduce the service life, and in serious cases, it is easy to have accident problems.
The transfer joint process consumes less energy and has strong adaptability to handle the separation of inorganic and organic materials. In the actual evaporation, the evaporation of equipment requires a large source of heat, in order to save energy at this stage more use detachable double flange loose sleeve force transfer joint to improve the efficiency of steam use to reduce energy consumption.
 
Removable double flange loose sleeve force transfer joint is unstable, high and low, vacuum fluctuations due to vacuum pump set failure, removable double flange loose sleeve force transfer joint water temperature is too high, the steam generated can not and condensation, resulting in steam vacuum equipment temperature is too high, affecting the operation of the equipment, the occurrence of running material. Improper operation, detachable double flange loose coupling is a common unit operation, the equipment operator should have knowledge of the structure, principles, performance, maintenance and can check the discharge of common faults.
