Used oil refined by centrifugal extraction machine process effect
When choosing equipment used oil refined extraction can be used in a reaction kettle, centrifugal extraction machine, chamfer of extraction equipment, but some equipment is not suitable for continuous operation in the process of operation.
Extraction reaction kettle in the used oil refined extraction due to processing time is long, complicated operation process, and will appear in the process of extraction entrainment, extraction such problems as incomplete, therefore, more and more customers are choosing centrifugal extraction machine oil refined extraction.
centrifugal extraction machine for refined oil extraction, are heavily dependent on the centrifugal force, the main work process is: the weight of two phase solution according to certain proportion respectively from two feeding tube into the drum and shell type ring gap formed between the mixed zone, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer.
Complete mixing and mass transfer process.
two phase separation process -
Mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall;
Small proportion of liquid phase gradually away from the drum wall and on to the center, after clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete two phase separation process.
centrifugal extraction machine is widely used in different areas of the extraction operation unit, because of the advantage of the centrifugal extraction machine:
1, simple structure, stable -
Using suspension single fulcrum structure, processing area at the bottom of the bearing and mechanical seal, no leakage risk, solved the centrifugal extraction machine failure frequently, the problem of short service life, save the costs for equipment maintenance.
2, energy saving,
Capacity bigger, more energy saving,
Under the condition of same capacity, its power consumption is a traditional annular structure of centrifugal extraction machine 1/10 ~ 1/3)
3, corrosion resistance,
Equipment is available in using perfluorinated polymer materials, resistant to strong acid,
Hydrochloric acid and mixed acid, etc. )
4, mixing, separation effect is good,
A variety of hybrid structure is optional, high separation efficiency, can be applied to easily emulsifying system.
5, heavy phase weir plate easy to change -
Material system changes, the heavy phase weir plate can realize quick change, the operation is simple and convenient.
6, equipment to save small amount of liquid -
The effective volume of equipment.
7, a high degree of automation,
Can realize online real-time monitoring equipment operation data, can be selected in accordance with GMP standard online cleaning system, fully able to adapt to the intermittent and continuous operation.
