Description :
Supply ST30 acid alkali resistant defoamer for desulfurization in power plants
The desulfurization specific defoamer SH-ST30 can effectively improve the application efficiency of cooling water and absorbent in the desulfurization tower, significantly reduce the opening frequency and number of circulation pumps, greatly increase salt production, and reduce on-site manual maintenance costs. The comprehensive benefits can be significantly improved.
2、 In the field of thermal power generation, ST30 defoamer is used for desulfurization in power plants and is applied in the production process of flue gas desulfurization. Its application methods and purposes are as follows. Currently, most thermal power plants in China adopt wet desulfurization. During the operation of the desulfurization device, the following factors can cause foaming of the absorption tower slurry, resulting in overflow of the absorption tower.
1. High speed reverse mixing of gas-liquid in the absorption tower
2. Imported flue gas dust exceeds the standard, such as impurities containing a large amount of inert substances
3. Poor coal quality, insufficient boiler combustion, or boiler oil injection causing imported flue gas to contain oil
4. The increase of heavy metal ions in the slurry of the absorption tower causes the increase of the slurry surface tension. 5. Limestone contains too much MgO, which not only affects the desulfurization efficiency, but also reacts with the root ions. The bubble in the slurry of the absorption tower caused by the above factors will cause the loss of a large number of neutralizing substances and cooling water, and also significantly reduce the reaction speed and product recovery rate, which seriously affects the operation process and desulfurization efficiency. At the same time, the massive overflow of foam will pollute the site environment, and will also bring major safety hazards and power losses to the motor room below the cooling tower.
If defoamers are used, the efficiency of cooling water and absorbent application can be effectively improved in the desulfurization tower, significantly reducing the frequency and number of circulating pumps, greatly increasing salt production, and reducing on-site manual maintenance costs. The comprehensive benefits can be significantly improved. As desulfurizer is required for flue gas desulfurization in thermal power plants, and the desulfurizer is limestone or limestone slurry, through practical attempts and laboratory test of foam data, the general defoamer has no obvious defoaming effect on the foam generated by desulfurizer absorber slurry, and its performance is different under specific foaming environment, so the defoamer should be comprehensively tested when applied to achieve efficiency.
3、 Application Fields
Widely used in sewage treatment, industrial cleaning, power plant desulfurization, cutting fluid, low-temperature printing and dyeing, and other fields;
4、 How to use
ST301 defoamer can be used directly or diluted in a certain proportion. It can be added after the production of foam or added into the product as a foam inhibiting component. According to different use systems, the amount of defoamer added is 0.5% -1 ‰, which is determined by the customer according to the specific situation.
5、 Packaging and Storage
This product is packaged in 50KG polyethylene drums or 200KG plastic drums, or customized according to customer requirements.
This product should be stored in a well ventilated and dry place, protected from rain and direct sunlight. It should not be mixed, transported, or stacked with strong acids, alkalis, or toxic substances.
This product has a storage period of 6 months from the date of production, provided that the above conditions are met. If there is a small amount of layering after the storage period, it can continue to be used after being mixed evenly and tested as qualified, without affecting its effectiveness.
This product is transported as non dangerous goods.
