The filtration precision is 0.5 ~50 μm. The system is fully enclosed to prevent contamination, which could provide excellent filter cartridges cleaning and regeneration performances. Timing or differential pressure PLC connected to DCS is used for system operation, which could be able to switch to long-term continuous operation.

APPLICATION CONDITIONS

Filtration and purification of industrial liquids at high and low temperatures; and col-lection of solid particles.

ADVANTAGES

Parallel operation of two or more units; online back washing; continuous and stable operation processes; long service life; automatic control; easy operation; convenient maintenance; small sewage discharge; and application in high temperature and corrosive conditions.

WORKING PRINCIPLE

Double-tank automatic back washing filter is composed of two filters (A and B) that are operated in parallel. During the normal filtration operation, one filter will be operated at full flow rate and the other one is used as backup. When the operation differential pressure of the system (the pressure drop between inlet and outlet) reaches the set value or the operation time of the system reaches the set value, the system will automatically switch the working filter to ensure the uninterrupted operation of the whole filtration system.

+ Purification of rich and lean amine liquid in amine liquid desulphurization system
+ Material and liquid purification with low waste discharge

 The metal membrane purification elements and components developed by AEET have won the first prize of the national invention award and many second prizes. 

PERFORMANCES

+ To purify the highly toxic aerosol gas at the very high concentration of 0.1~0.3μm generated under detonation conditions to the level that can meet the GB8703
+ Resistance to strong vibration (more than 500g)
+ Resistance to strong impact (0.5MPa ~ 2.0MPa)
+ High clogging capacity (25g ~ 500g)
+ High breathability (6m3/h ~ 10m3/h)
+ Compacted structure (Φ500x1000 ~ Φ500x1500 mm)

APPLICATIONS

The purification elements and components have an important role in the purification of hydrogen and its isotope gases, production of solid nuclear fuels, treatment of nuclear wastes and retired nuclear facilities, purification and discharge of nuclear waste gases and the civil nuclear power industry. 

This is a typical dynamic semi-cross process, realizing the integration of reaction and separation outside the filter. Using parallel cross technolo-gies, the device could effectively suppress the thickening of the filtration cakes. Thanks to its stable operation, adjustable clean filter liquid amount and high filtration precision as well as its automatic online inspection, automatic control and automatic back washing systems, and convenient maintenance, it is of great importance for enterprises to improve their product qualities, save resources, reduce energy consumption and improve environmental conditions.

ADVANTAGES

The whole equipment has such features as small space occupation, convenient installation and operation, low construction cost, no waste liquid discharge and high automation.

APPLICATIONS

Cross-flow filtration process could be used in a great variety of applications, especially for the separation of the reaction materials with high solid content (more than 25wt%). The process is not sensitive to the changes to the sizes, density and concentration of suspended particles, and has good anti-contamination capacity, which is applicable to large-scale and continuous production.

AEET’ s dust collector features in high precision, low pressure drop, long-term continuous operation and easy disassembly, which has been widely used in the continuous refactoring  facilities in numerous continuous catalytic Reforming facilities of China.
