Background technology
Slurry stripping tower is one of equipment crucial in polyvinyl chloride resin production process, with being constantly progressive for technology, PVC lifes
Production scale constantly expands, saves production cost, reduces labor intensity, the consciousness reinforcement for reducing energy consumption and the existing market demand
The fewer remaining vinyl chloride monomer the better in polyvinyl chloride resin, has become near using new and effective PVC slurry stripping tower process units
Development trend over year.Stripper is by aeration, and the gas being dissolved in liquid phase by gas-liquid counter current contact is separated,
Realize a kind of device of gas-liquid separation.Stripper generally selects air or water vapour as stripping medium, using packed tower or plate
Formula tower provides gas-liquid contact interface, and existing stripper is passed through steam for bottom straight tube, to adverse current under slurry carry out heating contact,
Gaseous phase outlet is generally located on the top of stripper, and bottom of towe is leakage fluid dram, and this operational mode, steam enters tower and is unevenly distributed, pressure
Power, flowed fluctuation range are larger, and stripper is run and brings destabilizing factor, and temperature, pressure difference are unstable in tower, residual slurry
To be more than 50ppm.
Invention content
In order to overcome the deficiencies of the prior art, a kind of air inlet of the utility model offer is evenly distributed, Srteam Stripping effect is good, mass transfer effect
Rate is high, the high-efficiency slurry stripper of stable and reliable operation.
The purpose of this utility model is achieved through the following technical solutions：
A kind of high-efficiency slurry stripper, including tower body, the top of tower body is equipped with gaseous phase outlet, and top is equipped with slurry import,
The lower part of tower body is equipped with the first steam inlet, and the bottom of tower body is provided with slurry outlet, is equipped with tower tray group in tower body, feature exists
In the top of the tower body is equipped with the second steam inlet, and the installation site of second steam inlet is less than the position of slurry import
It puts, the upper and lower part in tower body is respectively equipped with the second circle distributor and first annular distributor, the first annular distribution
Device is connect with the first steam inlet, and second circle distributor is connect with the second steam inlet, the first annular distributor
Top be equipped with the first cowling panel for being fixedly connected with tower body inner wall, first cowling panel is equipped with several through-holes.
Further, slurry distributor, the lower section of the slurry distributor are equipped in the corresponding tower body of the slurry import
Equipped with the second cowling panel being fixedly connected with tower body inner wall, second cowling panel is equipped with several through-holes, ensures that slurry is uniform
Enter tower body in.
Further, the tower tray group is made of 32 blocks be arranged in tower body round column plates, second steam inlet
It is set between the 8th ~ 10 piece of tower tray from top to bottom on corresponding tower body.
Further, the first annular distributor and the second circle distributor are fixed by dowel and tower body inner wall connects
It connects.
The beneficial effects of the utility model：First annular distributor, first annular distributor are equipped at first steam inlet
Top is equipped with the first cowling panel, ensure that the intake of steam is uniform and stable, makes the further rectification dispersion of slurry, increases slurry
The area contacted with steam counter-flow makes slurry temperature continue to increase, internal vinyl chloride（VC）It is constant to overflow；On tower body top
The second steam inlet is added, and installs the second circle distributor additional, being passed through for indirect steam makes top slurry temperature in initial contact
Degree raising, makes whole slurry dropping process thermally equivalent, and the temperature difference is smaller, ensure that the stability of temperature and pressure in tower, protects
Demonstrate,prove vinyl chloride in slurry（VC）It is lasting to overflow, improve mass-transfer efficiency.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
Technical solution described in the utility model is clearly and completely described below in conjunction with accompanying drawings and embodiments,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this practicality
Embodiment in novel, the every other reality that those of ordinary skill in the art are obtained without creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of high-efficiency slurry stripper, including tower body 1, the top of tower body is equipped with gaseous phase outlet 2, and top is set
There is slurry import 3, the lower part of tower body is equipped with the first steam inlet 4, and the bottom of tower body is provided with slurry outlet 5, is equipped in tower body
Tower tray group, tower tray group are made of 32 blocks be arranged in tower body round column plates, and the top of the tower body is equipped with the second steam inlet
6, second steam inlet is set between the 8th ~ 10 piece of tower tray from top to bottom on corresponding tower body, second steam inlet
6 installation site is less than the position of slurry import 3, and the upper and lower part in tower body is respectively equipped with the second circle distributor 8 and the
One circle distributor 7, the first annular distributor and the second circle distributor are fixedly connected by dowel with tower body inner wall,
