Defoamer for desulfurization XPJ-200A

 
Product introduction:

For the field of thermal power generation, the IOTA XPJ-200A products produced by the company are applied to the flue gas desulfurization production process. The specific application methods and purposes are as follows:

At present, most of China's thermal power plants use wet desulfurization. During the operation of the desulfurization device, the absorption tower slurry is foamed due to the following factors, resulting in overflow of the absorption tower.

(1) High-speed reverse mixing of gas and liquid in the absorption tower

(2) Imported flue gas dust exceeds the standard, such as impurities containing a large amount of inert substances

(3) The coal quality is not good, the boiler is not fully burned or the boiler is oiled to make the imported flue gas contain oil.

(4) Increased heavy metal ions in the absorption tower slurry, causing an increase in the surface tension of the slurry

(5) Limestone contains MgO excess, and the MgO excess not only affects the desulfurization efficiency, but also reacts with sulfate ions.

The bubble of the absorption tower slurry caused by the above factors will cause the loss of a large amount of neutralizing substances and cooling water, and also significantly reduce the reaction speed and product recovery rate, seriously affecting the operation process and desulfurization efficiency, and the large spill of foam pollutes the site environment. It will also bring significant safety hazards and power losses to the motor room below the cooling tower.

If the defoaming agent is applied, the application efficiency of the cooling water and the absorbent can be effectively improved in the desulfurization tower, the opening frequency and the opening amount of the circulation pump are significantly reduced, the output of the sulfate is greatly increased, and the site can be lightened at the same time. The cost of manual maintenance and comprehensive benefits can be significantly improved.

Because the flue gas desulfurization of thermal power plants requires the use of desulfurizer, and the desulfurizer is limestone or limestone slurry, after practical attempts and laboratory test foam data, the general defoamer eliminates the foaming of the tower slurry by the desulfurization device. The foaming effect is not obvious, and the performance is different under the specific foaming environment. The defoaming agent should be thoroughly tested to achieve the best performance.

Application of defoamer in seawater as circulating water:

In the production process of seawater as circulating water, because seawater contains a large amount of shellfish and seaweed organisms, water is in the process of circulation. Due to the suitable ambient temperature, the organism can easily block the pipeline and add chlorine gas to the circulating water to generate Hypochlorous acid kills shellfish, and the rotted animal carcass causes a large amount of foam to continue to form due to strong impact in the water, causing marine pollution. The XPJ-200A product produced by our company can effectively remove such foam, so as to effectively settle the pollutants and avoid pollution to the sea.

The use of defoamers in thermal power plants has effectively reduced environmental pollution.

Package:

25kg, 50kg, 200kg plastic drums and 200kg inner coated iron drums.

Storage and transportation:

It is suitable for storage at room temperature. Do not place it near the heat source. Do not expose it to sunlight. Do not add acid, alkali or salt to the defoamer. After dilution with water, it can not be stored for a long time. It will not be stratified within one year. If it exceeds this period, there will be delamination and demulsification. It can be stirred evenly before use, and it will not be affected by the use effect. It will be transported as non-dangerous goods.
