Supply of acid and alkali resistant defoamers for wet flue gas desulfurization plants

Description :

　　The application of acid and alkali resistant defoamers in the production process of flue gas desulfurization for wet flue gas desulfurization plants has the following application pathways and purposes. Currently, most thermal power plants in China use wet flue gas 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.

　　Hubei Xinsihai Chemical Co., Ltd,It is an industrial defoamer manufacturerThe main products include: organic silicon defoamer, GPE polyether defoamer, mineral oil modified defoamer, polyether modified silicon defoamer,Recommended by Mr. WangFor example, grout powder defoamer, water-based latex paint defoamer, water-based paint defoamer, sewage treatment defoamer, industrial glue defoamer, industrial cleaning defoamer, cutting fluid defoamer, power plant desulfurization defoamer, water-based ink defoamer, etc., where there is foam, we can add it wherever there is, with fast defoaming, low consumption, no residue, effectively improving production efficiency and solving the foam problem. We are serious. The company has long been committed to the design and research and development of the food processing industry, accumulating rich technology and experience, providing users with excellent products, and offering defoamer solutions or technical services according to user product requirements.

　　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 absorption tower slurry causes an increase in the surface tension of the slurry

　　5. Limestone contains too much MgO, which will not only affect the desulfurization efficiency, but also react with the root ions. The bubble of absorption tower slurry 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, seriously affecting the operation process and desulfurization efficiency. At the same time, a large number of foam overflows will pollute the site environment, and will also bring significant potential safety hazards and power loss 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、 The application of defoamers in seawater circulating water. In the production process using seawater as circulating water, due to the presence of a large number of shellfish and seaweed organisms in seawater, the water in the circulating process can easily clog pipelines due to the suitable environmental temperature. Adding hypochlorous acid to the circulating water generates hypochlorous acid to kill shellfish organisms, and the decaying animal carcasses in the water are highly affected; The hit caused a large number of foam to continue to generate, resulting in marine pollution. The products produced by our company can effectively remove such foam, so as to effectively settle pollutants and avoid pollution to the sea. The application of defoamers in thermal power plants effectively reduces environmental pollution.
