Embodiment
[0017] A method for protecting the tube plate of an esterification condenser, the steps are as follows:
[0018] 1) After the esterification reaction, the alcohol vapor is transported through the liquid alcohol area;
[0019] 2) The liquid alcohol is pressurized and atomized, and the atomized liquid alcohol is in contact with the alcohol vapor for mass transfer and heat transfer;
[0020] 31) Through step 2), the alcohol vapor whose temperature drops to 103°C-130°C is sent to the condenser;
[0021] 32) In step 31), the secondary alcohol is added synchronously, and the added secondary alcohol is carried out in step 2)
[0022] 4) The alcohol vapor whose temperature has dropped to 103°C-130°C is in contact with the condenser tube to continue cooling down.
[0023] Step 32) secondary alcohol addition is 2.5m3 / h.
[0024] Cooling water is passed through the tubes of the condenser, and the difference between the inlet temperature of the cooling water and the temperature of the ...
