Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flocculation and sedimentation for water treatment, and is an anti-caking, efficient and convenient dispensing device. Background Art
[0002] The coal chemical production process mainly uses coal as raw material and undergoes a series of chemical and physical processes such as pressurized gasification, washing and flash evaporation after pulping to convert coal into gaseous, liquid and solid products. The wastewater generated by this production process is mainly high-concentration coal gas washing wastewater, which has a large amount of water and contains a large amount of solid suspended particles, ammonia nitrogen, COD and other toxic and harmful substances. If it is not handled properly, it is easy to cause water pollution and evolve into water quality-type water shortage. Therefore, wastewater treatment is an issue that all coal chemical projects need to consider. The coal chemical industry consumes a lot of water resources and generates a lot of wastewater. Therefore, water-saving technology and sewage treatment technology have become the key to the development of the industry.
[0003] Polyacrylamide, with the molecular formula (C3H5NO)n, is a linear organic high molecular polymer. At the same time, it is also a high molecular water treatment flocculant product. It plays a linking and bridging role between particles, allowing fine particles to form relatively large flocs, and accelerates the sedimentation rate, reducing the content of particulate matter in the water, providing effective protection for the deep treatment of sewage.
[0004] Under normal circumstances, the flocculation effect will increase with the increase in the amount of polyacrylamide used, but when the concentration is too high, the effect will decrease and it will turn back into a stable colloid. Therefore, the preparation process of the flocculant is particularly critical.
[0005] When preparing flocculant solution, the following issues should be paid special attention to: 1. Do not use high-speed stirring, and do not stir for too long; 2. Do not have large pieces; 3. Avoid contact with ironware; 4. The dissolution temperature should be low, such as 50℃ to 60℃ or below; 5. Use clean soft water, not turbid, rusty or high-hardness water; 6. The dissolution process should be completed in one go, that is, directly dissolve to the concentration used, and should not be dissolved into a high concentration and then diluted; 7. The dissolution equipment should be round and have no dead corners. The dissolution of flocculants with very high molecular weight is relatively slow. Its powder particles first absorb water and swell, and then gradually diffuse and disperse. The initial solution is very uneven, and it takes a while to stir to reach a consistent concentration. Good equipment and operation are required to complete this process efficiently in a suitable time. Summary of the invention
