There are three main problems in the use of circulating cooling water in power plants: 1. Corrosion to equipment and pipelines is related to water quality and metal properties. 2. Scaling of equipment and pipelines is caused by the precipitation of compounds that dissolve and decrease as the temperature rises. 3. Microbial growth and contamination, consisting of suspended solids, corrosion products, microbial corpses and their extracellular polymers.
The above factors will weaken the working efficiency of the equipment system. Since microbial growth and fouling are the main problems in circulating cooling systems. The cyclone desander is combined with the chlorine dioxide generator, because chlorine dioxide is a strong oxidant, which can better oxidize the sulfur ions contained in the circulating cooling water into sulfate ions, and can be related to various chemical genes Therefore, it can effectively prevent the corrosion and scaling of equipment, pipelines, cyclone desanders, etc. due to water quality and metal properties, and can be used as a pretreatment for membrane treatment.
The cyclone desander is a new type of separation equipment that is made according to the screening principle of solid particles in the fluid when the desand body particles rotate in the desander, and then combined with filtering measures. When the water flow enters the equipment tangentially from the desander inlet of the cyclone desander under a certain pressure, it will produce a strong rotational motion. Due to the different densities of sand and water, the centrifugal force, centripetal force, buoyancy and fluid drag Under the action, The water with low density rises and is discharged from the water outlet, and the sand with high density is discharged from the sewage outlet at the bottom of the equipment. The individual tiny particles that float together along the water flow are blocked by the second-stage filter device, so as to achieve the purpose of sand removal. Compared with the current cyclone sand remover on the market, the filter unit is added (filter accuracy can be selected by the user), With high sand removal rate, It has the advantages of saving installation space, low missed capture rate of individual tiny solids, and stable working conditions.
