New process of brine refining without preprocessor

The SST membrane assembly, with the following characteristics:

1. The biggest feature of the SST membrane tube is the anti-pollution layer, which can effectively remove Mg (OH) 2 and some organic matter, without

Need to adapt, can fully realize the no preprocessor of brine refining process.

2. The membrane tube has no support, and is resistant to strong acid, strong alkali and free chlorine corrosion.

3. The membrane tube adopts stretching technology to form a high-strength seamless tube with a service life of more than 3 years. After special treatment,The surface of the membrane tube is delicate and smooth, and the coefficient of friction is low, thus in the reverse Make the filter cake is easy to fall off, no mud phenomenon, pickling square convenience.

In the process of washing

4. The membrane aperture is 0.2 microns and the mass of filtered brine

SS 1.0 ppm, the membrane pores were uniform and dense.

5. The membrane tube adopts PTFE primary forming technology to hot melt the bottom

Sealed, with no structural leakage.

New process of primary brine refining without preprocessor

The new generation of preprocessor brine refining process has been introduced into China in 2011

Thirteen users have already used the process. The operation proved that the process has stable operation, reliable water quality

Low operation cost, less construction investment, high level of operation control, less labor cost and a series of advantages, are the current

With the world advanced level of a brine refining technology.

Comparison with the inorganic film without the preprocessor process

1, realize the low-pressure surface filtration, ePTFE membrane hole

The diameter was controlled at 0.2 μ m, with high filtration accuracy and stability

Reliable, the SS value of filtered refined saline is guaranteed at 1.0

Below ppm, there will never be above 5.0ppm

In the case of.

2. The system operating pressure is low, and the energy consumption is significantly reduced. The same 30 0,000 tons / year caustic soda saline plant, only electricity per year

A fee can save you $1.4 million yuan.

3, the use of ePTFE microfilter membrane, high strength, acid and alkali resistance, will never appear fracture phenomenon, let alone because of the system

Safety accident caused by fracture in unified high pressure operation.

4, the system sludge concentration ratio is more than 100 times, the concentrated liquid does not need to thicken, the required plate and frame press is only no

Machine film process is less than half.

Contrast with the organic film equipped with a preprocessor process

1. The existing device can improve the brine treatment capacity by 40% after transformation

Take the 30 0,000 ton / year caustic soda saline device as an example, use the existing filter, after modification to use no preparation

In the tally process, the brine processing capacity can be increased by up to 40%, reaching more than 42 0,000 tons.

2, less investment in new equipment, occupy a province

This device requires no preprocessor, coarse filtration, filtration circulation system, and filter concentrated water

The thickening device. Reduce the overall investment of the unit compared to the old process.

Taking the 30 0,000 ton / year caustic soda saline plant as an example, the investment can be significantly reduced by 12.8 million yuan. The new process can be

Save two DN15000 pretreatment devices, each cost 5 million (including foundation); save pressurized dissolved gas installation

Put two sets, save investment of about 1.5 million; civil engineering investment of about 1 million; due to no preprocessor process discharge

The salt and mud solid content is high, so the number of filter press is small, can reduce the investment of 30 0,000 yuan, other aspects of two processes

The investment situation is basically equal according to the different allocation, a total of investment reduced by 12.8 million yuan.

3. The quality of the refined brine is stable and reliable

Using state-of-the-art SST series anti-pollution membrane products with very high filtration
