It is favorable for concentration of high concentration material, and can expand working range of membrane separator.
Description
Technical field:
The present invention relates to a kind of special equipment that utilizes membrane separating method, especially a kind of vibrated bed membrane separator.
Background technology:
Membrane separator is to utilize small aperture of face and charge, different molecular weight in gas or the liquid or different electrical material is implemented the equipment that separates.Membrane separator has been applied to the desalinization desalination at present; Drink, the medicinal water removal of impurity and bacterium; The industry high purity water removes charged ion; Remove thalline in the bioengineering zymotic fluid, concentrate macromolecular substances; Effective component extracting in pharmaceutical engineering, the daily use chemicals engineering; Be used for sewage purification and reuse in the environmental protection; The Alcohol Production that is used for high concentration, low energy consumption in the Alcohol Production; Atomic energy engineering is used for radioactive wastewater and separates radioactive substance etc.The purposes of membrane separator more and more widely, the someone proposes: " having grasped the tomorrow that membrane technology just equals to have grasped Chemical Engineering ".
But membrane separator will guarantee effective application in actual engineering, must solve the problem of film surface pollution.In engineering, a part of material passes face, and a part of material is held back by face.The material that is trapped can progressively form one deck concentration difference adsorption layer from inside to outside at face, and adsorption layer is thickeied to a certain degree, will influence the flow velocity of the material that passes film, and the operating efficiency of film progressively reduces, even the face obstruction can occur, and membrane separator is quit work.Therefore to guarantee that membrane separator works effectively, generation or thickness that must control concentration difference adsorption layer.
In existing film Engineering Design Manual and data document books about film, be of the influence of control concentration difference adsorption layer to the film operating efficiency, generally adopt following method:
1. regularly Chemical cleaning is removed adsorption layer, to keep the cleaning of film.Chemistry regularly cleans the continuous operation that has influenced membrane separator, and the membrane separator operating efficiency is descended, and the cost height that cleans, and inconvenient operation is cleaned effluent and also need be handled to solve the pollution to environment.
2. compressed air oppositely blows down the removal adsorption layer.Compressed air oppositely blows down, and also can influence the continuous operation of membrane separator, and the membrane separator operating efficiency is descended, and has increased processing cost, inconvenient operation.
3. form high-velocity stream at face.By flowing of face high speed object, adsorption layer is destroyed and takes out of membrane separator.To form high-velocity stream at face, need to strengthen the internal circulating load of material handling, therefore increase the consumption of membrane separator power, increase processing cost.And this method should not be used for the concentrating of object of high concentration.
4. change the operative orientation of film device, make the neuston direction of flow opposite, make face hold back colmatation zone and come off.This method makes the control of film system complicated, and valve is many, and the material that comes off might be sneaked into again in the material that needs to handle, and has increased the difficulty of handling.
Summary of the invention:
The purpose of this invention is to provide a kind of method for designing, can reduce of the influence of face adsorption layer dirt, make membrane separator energy continuous high-efficient rate, low-cost work film work.
Vibrated bed membrane separator of the present invention is made up of membrane separator and vibrated bed two parts of routine.Designing requirement is as follows:
1, conventional membrane separator is fixed on the vibrated bed, feed and exhaust tube connects with flexible pipe with outside, and membrane separator can be moved back and forth with vibrated bed.
2, vibrated bed produces under the external force effect that motor produces and moves back and forth, and reciprocating direction is vertical with the direction that material penetrates film, promptly does the reciprocating motion that vertical material penetrates the film direction with vibrated bed.
Membrane separator can be flat sheet membrane separator, tubular membrane separator, capillary-pipe film separator, rolling diaphragm separator and hollow fiber membrane separator.
Vibrated bed can be electric vibrating bed, pneumatic vibration bed and hydraulic vibration bed.The electric vibrating bed can be eccentric gravity self-excited vibration bed or eccentric ratio forced vibration bed.Vibrated bed can be designed to resonance bed and off-resonance bed.
When equipment moves back and forth, can produce shearing along the direction of motion between object that it is surperficial and the equipment as everyone knows, the direction of shearing is opposite with the direction of motion.When the reciprocating frequency of membrane separator and amplitude acquire a certain degree, when the reciprocal shearing that membrane separator is parallel to face is attached to the cohesive force of face material greater than dirt, can make dirt can not form the face that firm adhesion layer stops that object passes through, the established concentration difference adsorption layer of face is destroyed and come off.By the reciprocating mode of vibrated bed is the membrane separator of main control film surface contamination, can be described as the vibrated bed membrane separator.The vibrated bed membrane separator can be realized the work of film system long-term stability, and the high concentration that can be used for holding back material concentrates.
Advantage of the present invention is:
(1) the effectively pollution of controlling diaphragm separator face of vibrated bed makes the longer high-efficiency stable work of vibrated bed membrane separator;
(2) the vibrated bed membrane separator helps concentrating of high concentration material, has enlarged the range of application of membrane separator;
(3) consumption little, power of vibrated bed volume is few, utilizes the design of resonance bed, and power consumption is littler, can reduce the processing cost of membrane separator.
