Ⅰ、Adding ingredients

1.When feeding, there should be no hard objects, block metal, rope and tape falling into the equipment to prevent damage to the glass lining layer, and the rope and tape will wind the thermometer casing and stirrer in the tank and cause fracture. For large hard materials, should be crushed after adding, such as the reactant particles will cause wear on the porcelain surface, to add less, more often.

2.From the pipe mouth to add strong corrosion will directly cause exothermic reaction of the material. Such as adding sulfuric acid, nitric acid, such as concentrated sulfuric acid and other strong corrosive media, it is easy to produce a large amount of heat, if directly into the pipeline or tank after adding, the first to control the feeding speed, the second is best to use the anti - corrosion material tube made of showbath head insectie into the pipe mouth of the appropriate distance to feed, to prevent local temperature exceeding the damage to the glass - lined porcelain layer. Try to avoid cold tank heating later. That to avoid cold tank heating later. By to avoid cold tank heating by the proper adding cold material. Due to the sudden change of temperature, internal stress is formed, which affects the service life.

Ⅱ、Operation

1.The heating and pressure boost of the jacket equipment should be pressurized and heated slowly

①Open the pneumatic valve to 20%, and control the pressure within 0.1MPa for 10 minutes;

②After 10 minutes, the pneumatic valve is opened to 50%, the pressure is controlled within 0.2MPa, and it is kept for 10 minutes;

③After 10 minutes, the pneumatic valve is opened to 70%, the pressure is controlled within 0.3MPa, and it is kept for 10 minutes;

④After 10 minutes, the pneumatic valve is opened to 100%, and the pressure is controlled at the operating pressure of the reaction tank and prolongs the pressurization time.

The whole process takes 30 minutes, which effectively alleviates the occurrence of sudden temperature difference of the reaction tank and prolongs the service life.（The pressure increase rate is 0.1MPa pressure per 10 minutes）

2.Use temperature and medium requirementsOur equipment use temperature 0℃ - 200℃ or - 196℃ - 200℃, temperature difference thermal impact 120℃, cold impact 110℃. (Beyond the above temperature range, it is indicated in the order contract and designed and manufactured separately). In use, the acid into the jacket is strictly prevented to prevent the metal hydrogen evolution reaction of the glass lining layer, causing the glass lining layer to explode due to scaling.

3.Jacket exhaust hole

①After the equipment runs for a period of time, there will be non - condensable gas accumulated on the top of the jacket, occupying the jacket space and reducing the heat transfer performance of the jacket.

②The concentration of free hydrogen atoms in non - condensable gas is high, and free hydrogen will penetrate, diffuse and accumulate into the metal matrix, forming hydrogen, and the pressure will rise for a long time, resulting in the porcelain layer bursting. Therefore, the steam release hole also has the function of protecting the equipment.

Ⅲ、Process

1.Pay attention to the sealing conditions of flanges, manholes, mechanical seals, discharge valves, etc. If leakage is found, immediate measures should be taken to prevent metal matrix corrosion and damage to the sealing surface.

2.Try to avoid contact between the tank shell and the acid solution to prevent damage to the glass - lined porcelain surface due to corrosion of the iron tire. If there is any acid contact, it should be immediately neutralized and then rinsed with water.

3.When the acid and alkali are used alternately, the acid should be added first and then the alkali, and the internal pipe should always be used when the alkaline material is added (a protective sleeve processed with tetrafluoroethylene plastic, and the sleeve is in the inner wall of the pipe mouth to prevent the alkaline material from hanging on the wall corrosion).

4.If the transmission device has abnormal noise, it should be checked and processed in time.

Ⅳ、Material discharge

1.When discharging, if the discharge valve and discharge pipe are blocked, use non - metal tools to gently open, do not touch. If you find porcelain layer debris, you should immediately open the tank to check the damaged porcelain surface and repair it before use.

2.When cleaning the tank, no metal utensils can be used, and the materials stuck on the inner surface of the tank must be cleaned promptly and thoroughly.
