Abstract
Metal ion removes filter in a kind of isopropanol water solution, including tank body, tank body top is provided with feed pipe, and bottom is provided with leakage fluid dram, material distributor, cation exchange resin layer and draining cap layers, feed pipe are disposed in tank body from top to bottom to connect with material distributor.The material distributor includes central tube, and the cloth tube to radially distribute is connected on central tube.The feed pipe is connect with central tube.Isopropanol water solution enters after tank body through material distributor evenly into cation exchange resin layer, adsorbs metal cation and cation exchange resin layer in material, achievees the purpose that removal.The isopropanol water solution of removal metal cation is passed through by drain cap again, and resin will not flow out.The configuration of the present invention is simple effectively removes the metal cation in isopropanol water solution, and catalyst needed for protecting esterification avoids catalyst poisoning, it is ensured that esterification is normally carried out, and extends the service life of catalyst.
Description
Technical field
The present invention relates to a kind of for removing the device of metal ion in isopropanol water solution, to protect needed for esterification
Catalyst, belong to metal ion removal technology field in aqueous solution.
Background technique
Isopropyl acetate has versatile, but be recycled as extractant as a kind of important organic solvent
During, decomposition is generated in acid condition, resolves into acetic acid and isopropanol, with the progress of decomposition, isopropyl acetate
Content reduces, and influences being normally carried out for extraction process.
Isopropanol can carry out distillation extraction by isopropanol tower, obtain the isopropanol water solution of content about 20% or so.
Under the action of special catalyst, isopropanol water solution and acetic acid will generate isopropyl acetate, the vinegar of generation by chemical reaction
Isopropyl propionate is again introduced into extractant system.It is substantially reduced the amount of supplement isopropyl acetate by this way, realizes isopropyl
Alcohol reuse, production cost are greatly lowered.But it will cause in isopropanol water solution there are metal cations such as calcium, magnesium, iron
Catalyst poisoning influences being normally carried out for esterification.
Heavy mental treatment technology is broadly divided into four major class in water at present: physical-chemical process, absorption method, microbial method with
And membrane separation technique, can according to the difference of the difference of concentration of heavy metal ion, the difference of type, the difference in source and form come
Select processing technique appropriate.But these methods will solve the problems, such as many in practical applications, can not be directly suitable for isopropyl
The removal of metal cation in alcohol solution, it cannot be guaranteed that simple and quick be effectively removed.
Summary of the invention
The present invention provides a kind of structure for deficiency existing for metal cation removal technology in existing isopropanol water solution
Simply, the filter of metal cation in isopropanol water solution is effectively and reliably removed.
Metal ion removes filter in isopropanol water solution of the invention, using following technical scheme:
The filter, including tank body, tank body top are provided with feed pipe, and bottom is provided with leakage fluid dram, and tank body internal upper part is set
It is equipped with material distributor, cation exchange resin layer, distribution below cation exchange resin layer are provided with below material distributor
There is drain cap, feed pipe is connect with material distributor.
The material distributor includes central tube, and the cloth tube to radially distribute is connected on central tube.The charging
Pipe is connect with central tube.Fluid hole is distributed on the cloth tube.
The drain cap uses existing structure, such as tower drain cap, filter cap.
Isopropanol water solution enters after tank body through material distributor evenly into cation exchange resin layer, makes material
In metal cation adsorbed with cation exchange resin layer, achieve the purpose that removal.Remove the isopropyl of metal cation
Alcohol solution is passed through by drain cap again, and resin will not flow out.
The configuration of the present invention is simple effectively removes the metal cation in isopropanol water solution, protects needed for esterification
Catalyst avoids catalyst poisoning, it is ensured that esterification is normally carried out, and extends the service life of catalyst, reduces production
Cost.The filter also extends in the actual production of other liquid removal metal ions.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of material distributor in the present invention.
In figure: 1. tank bodies, 2. feed pipes, 3. material distributors, 4. cation exchange resin layers, 5. drain caps, 6. drains
Mouthful, 7. central tubes, 8. cloth tubes.
Specific embodiment
Metal ion removes filter in isopropanol water solution of the invention, as shown in Figure 1, including tank body 1, on tank body 1
Portion is provided with feed pipe 2, and bottom is provided with leakage fluid dram 6.Feed pipe 2 is connect with the material distributor 3 in tank body 1, material distribution
The lower section of device 3 is provided with cation exchange resin layer 4, and multiple drain caps 5 are distributed in the lower section of cation exchange resin layer 4, row
Water cap 5 uses existing structure, such as tower drain cap, filter cap.
The structure of material distributor 3 is as shown in Fig. 2, include central tube 7, design has radial be connected on central tube 7
Fluid hole is distributed on cloth tube 8 in cloth tube 8.Feed pipe 2 is connect with the upper end of central tube 7.Material enters by feed pipe 2
Then central tube 7 is discharged by radial cloth tube 8, realize uniform distribution.
Isopropanol water solution is entered after tank body 1 through material distributor 3 by feed pipe 2 evenly into cation exchange tree
Rouge layer 4 adsorbs metal cation and cation exchange resin layer 4 in material, achievees the purpose that removal.Remove metal
The isopropanol water solution of cation passes through drain cap 4 again and is pierced by, and cation exchange resin will not flow out.
Above-mentioned filter is incorporated in isopropanol esterification system, periodically to the measurement of metal ion content in material after filtering,
Cation exchange resin is regularly replaced, realizes continuous use.
