Abstract
The invention discloses a kind of acetic acid rectifying and dewatering Tower Systems, cold blowing gas air inlet pipe and regeneration gas escape pipe, the bottom of the process equipment is equipped with the second blow vent, clean gas escape pipe, cold blowing gas escape pipe and regeneration gas air inlet pipe, this molecular sieve water separation tower, the equal face tower body setting in the outlet side of gas distributor are installed at second blow vent, make gas being distributed in tower body more evenly, keep the intracorporal molecular sieve water sucting degree of tower roughly the same, extend dewatering time, improves dehydration efficiency.
Description
Technical field
The present invention relates to molecular sieve dehydration technical field, specially a kind of acetic acid rectifying and dewatering Tower System.
Background technique
Existing molecular sieve water separation tower, it cannot be guaranteed that gas uniformly divides not in tower body, is led in dehydration, regenerative process
It causes the intracorporal molecular sieve water suction of tower, degree of dehydration different, causes regenerated frequency to improve, increase production cost；Some molecules
Sieve dehydrating tower molecular sieve is only laid in stainless steel wire, and online, molecular sieve water swelling is reduced since the number of molecular sieve is more
The influence that molecular sieve gravity expands molecular sieve.For this purpose, it is proposed that a kind of acetic acid rectifying and dewatering Tower System.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of acetic acid rectifying and dewatering Tower System
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of acetic acid rectifying and dewatering Tower System, including tower
Body, upper cover, process equipment and molecular sieve, are respectively and fixedly provided with positive flange at the top and bottom of the tower body, the bottom of the upper cover and
Anti- flange is respectively and fixedly provided at the top of process equipment, the positive flange at the top and bottom of the tower body pass through bolt respectively with upper base
Portion is fixedly connected with the anti-flange at the top of process equipment, and the top of the upper cover is equipped with the first blow vent, first blow vent
Place is equipped with wet purification gas air inlet pipe, cold blowing gas air inlet pipe and regeneration gas escape pipe, and the bottom of the process equipment is equipped with second
Blow vent is equipped with clean gas escape pipe, cold blowing gas escape pipe and regeneration gas air inlet pipe at second blow vent, described
Stainless steel wire filter is fixed at tower body medial center, the surface that stainless steel wire filter is located on the inside of the tower body is fixed in parallel
There are two automatic washing brush device, the underface of stainless steel wire filter is located on the inside of the tower body, and fixed in parallel there are three full-automatic
Cleaning machine between the automatic washing brush device, is filled with porcelain ball, is located at not on the inside of the tower body between automatic washing machine
The two sides of rust steel wire spacer are symmetrically fixed with third stainless steel cloth, be located on the inside of the tower body stainless steel wire filter and it is complete from
Molecular sieve is filled between stainless steel wire filter and automatic washing machine between dynamic washing and brushing device and on the inside of tower body.
