After the technology develops, relevant child also had very great progress, reclaim with acetic acid ester for rectification tower, a few unit were added on the foundation of original equipment construction, and the result that gets eventually is big different. The acetic acid ester that there is a kind to contain heater here reclaims rectification tower, see its design plan together.
Compare with photograph of traditional rectify tower, new-style acetic acid ester reclaims the unique design in rectification tower is much a heater, be located in tower bottom and tower system interior respectively. It is among them by the tower the vapour heater of upper part is by a vapour distributinging canal is comprised, and one aspect of the matter crosses tower body lateral, for finer implementation stock deferent, the mouth of the stock inside corresponding tower is set on steam distributinging valve. Through vapour when vapour the entrance enters vapour heater, pass a mouth ejective with reclaim the stock of rectification tower interior is contacted directly, complete the process such as hot exchange, qualitative exchange thereby. The vapour heater texture that after be, adds is very simple also, want to assure to reclaim of rectification tower move normally, vapour heater is the foundation of safeguard.
