Have stimulating effect to eye, skin, mucous membrane, can
pollute water source. Toxic sulfide flue gas is produced by high
thermal decomposition. Industry is mainly used in making sulfite
cellulose ester, sodium thiosulfate, organic chemicals, bleaching
fabric, etc., but also used as reducing agent, preservative,
chlorine agent, etc.
1.It is used for the microanalysis and determination of tellurium
and niobium and the preparation of developing solution.
2.Printing and dyeing industry as a deoxidizer and bleaching
agent, used in the cooking of various cotton fabrics, can prevent
the local oxidation of cotton fiber and affect the fiber
strength, and improve the whiteness of the cooking materials.
3.Food industry used as bleaching agent, preservative,
loosening agent, antioxidant.Also used in pharmaceutical
synthesis.

3) quality control：
Our raw materials are directly obtained from the origin
Our production line is fully equipped and regularly checked and
cleaned to ensure that no impurities in the environment affect
production. Each step is supervised and operated by high-tech
staff. Our absorption tower adopts counter-current operation.
During product synthesis, sulfur dioxide is introduced from the
bottom of the absorption tower to conduct strong disturbance and
full reaction with soda ash solution, while reducing mass
transfer resistance and improving absorption efficiency. After
the sulfite solution is generated, slowly add the soda ash
solution to neutralize it until it is slightly acidic, and then
add the soda ash solution to make the pH *1~*2. After
decolorization and filtration, the clarified solution is
evaporated, crystallized, centrifuged, and dried by air flow at
**0~**0 ℃ to obtain our anhydrous sodium sulfite product.
Our workers will do the following at work:
1. Wear labor protection articles as required and work with
certificates.
2. Understand the equipment operation, remaining problems and
precautions of the shift. Check the safety facilities, equipment
operation and civilized production according to the shift
handover.
3. According to the content of shift handover, the shift handover
personnel shall conduct detailed inspection together with the
shift handover personnel on site. After confirming that there are
no problems, the shift handover personnel shall be allowed to
fill in the shift handover record together.
Check the equipment as follows:
1. Check whether the screen is damaged or holed, whether the
screen gap is excessively worn, and whether there is coal
accumulation on the screen.
2. Check whether the damping rubber spring is complete and
whether it is damaged or aged.
3. Whether the oil quantity and quality of the lubricating oil
tank meet the requirements and whether there is oil leakage.
4. Whether the rotating parts operate flexibly.
5. Whether the feeding and discharging chutes and centrifugal
liquid chutes are unblocked.
6. Check whether all detection instruments are in good condition.
7. Whether the safety shield is firm and reliable.
8. Frequently understand the moisture content of the dehydrated
product, observe the flow rate of the centrifugal liquid and the
particle size composition of the solid to analyze its working
condition, and judge whether there is screen blockage, excessive
wear of the screen hole, and screen damage.
9. The feed of the dehydrator shall be kept uniform to avoid
clogging of the feed inlet.
*0. Practical and effective measures must be taken to remove the
sundries in the feed, especially iron ware. Strictly prevent
iron, sundries and large coal from entering the centrifuge
dehydrator to avoid damaging the equipment.
