Sodium sulfide is a kind of chemical items, mention chemistry, we think of is chemical experiment, in the experiment without instrument is the filter, actually for filter, most people saw small during the school, we common small filter in chemistry class, but used in chemical plant are generally large filter instrument, let’s go to see what filter instrument.

Filtration is a kind of operation of separating solid particles suspended in liquid or gas. Many equipment are used for filtration. Here, several common instruments are mainly introduced here, for the reference of producers only.

(1) Tube filter

It is composed of porous filter tube, easy for insulation and filtration, and is used to purify very fine impurities in the filtrate, such as capacitor borax, barium carbonate, etc.

(2) Three-legged centrifuge

Forming products. Smooth operation, small footprint, easy to control the separation and washing time, but long filtration cycle, small production capacity, high labor intensity. For crystalline separation of inorganic salts, such as copper sulfate, sodium erysalum, etc.

(3) Taper-type continuous centrifuge

Formed products, continuous filtration, unloading, simple structure, convenient maintenance, but washing is not good, the filter slurry is small solid ratio, large leakage, suitable for the separation of large particles uniform crystallization, such as borax.

(4) Spiral unloading settlement centrifuge

Continuous filtration, filter cake can be washed, the filtrate contains 1-7%, suitable for the separation of large changes, large difference of suspension, there are vertical and horizontal. For the filtration of calcium carbonate and nickel sulfate.

It can be seen that there is more than one filter instrument, but for different types of filter instruments, and our sodium sulfide also needs such an instrument in the experiment. If you have a demand for or are interested in sodium sulfide, you can contact us, we will provide you with excellent performance products, will make you satisfied.sulfure de sodium hydraté
