1、 In modern industrial production, many devices require corresponding desulfurization, denitrification, and dust collectors for protection during operation;. This is mainly to purify as much as possible some polluting substances generated during the production process, such as SO2, nitrogen-containing oxides, etc., in order to achieve compliance with emission standards. As users, in the process of using desulfurization, denitrification, and dust removal equipment for purification, we also need to take measures to improve its purification effect and appropriately extend the service life of the equipment. Overall, appropriate protective measures are very beneficial for users. In fact, from the perspective of current technology analysis, the various desulfurization, denitrification, and dust collectors we use sometimes have some shortcomings. Therefore, maintenance work becomes important. So, do you know what issues we need to pay attention to during the operation of desulfurization, denitrification, and dust collectors? Users who have used desulfurization, denitrification, and dust collectors should be aware that vortices may form inside the equipment during operation. And once such a problem arises, it is almost impossible. Especially when encountering condensation that may form due to temperature and velocity changes of dusty gases, we need to regularly clean them. In addition, in the daily use of desulfurization, denitrification and dust collectors, we also need to strengthen management systems, especially paying attention to regular inspections of equipment, in order to timely detect abnormal problems and take targeted measures to deal with them. Otherwise, it may be difficult to achieve the expected purification effect. 2、 As the domestic economic level continues to develop for desulfurization, denitrification, and dust collectors, the pollution of the atmospheric environment is becoming increasingly severe, which has had an impact on our production and daily life. However, with the increasing awareness of environmental protection, people are paying more and more attention to the issue of atmospheric protection. At the same time, the domestic policy driven approach is also relatively strong, which has provided great room for improvement and optimization potential for domestic flue gas desulfurization, denitrification, and dust collectors. However, in the process of using desulfurization, denitrification, and dust collectors, there has always been a problem that troubles manufacturers and users, and this problem is the technology of desulfurization, denitrification, and dust collectors. Everyone should know that when using desulfurization, denitrification, and dust collectors for flue gas treatment, due to the presence of a large amount of corrosive substances, the equipment itself also faces the risk of corrosion. So, is there a more suitable method to avoid such problems as much as possible? Now let's analyze it. First, we need to control the pH value reasonably. Secondly, during the operation, the inlet temperature of the flue gas should be strictly controlled, and matching accessories should be selected to minimize corrosion as much as possible. Once again, it is important to strictly control the quality of the manufacturing process when making accessories. In addition, when selecting materials, suitable materials with performance should also be chosen, such as carbon steel body lining materials or alloy materials used to control the degree of corrosion. In current production work, people are paying more and more attention to environmental protection issues, especially in thermal power plants where a large amount of SO2 and nitrogen oxides are generated during the production process, which can cause serious pollution to the atmosphere. Therefore, accelerating the research and production of desulfurization, denitrification, and dust collectors plays an important role in achieving sustainable development. 3、 There are many working conditions where desulfurization and denitrification dust collectors are used in conjunction with cyclone dust collectors. Only using desulfurization and denitrification dust collectors can meet environmental standards, so other dust collector equipment is needed as an auxiliary. Some working conditions require both desulfurization and dust removal treatment, so in order to meet environmental requirements, desulfurization and dust removal need to work together. In general, dust recovery or dust with high sulfur content is required to achieve the effect of removing dust. Next, we will introduce the mutual use of desulfurization and denitrification dust collectors and cyclone dust collectors. Desulfurization and denitration process of the desulfurization and denitration dust remover: the flue gas enters the desulfurization and denitration dust remover. Due to the increase of the cross-sectional area, the flue gas flow rate slows down. The spray system and fluidized bed structure designed according to the chemical reaction mechanism and fluid mechanics principle combine the spray absorption and foam layer absorption together. The negative gas liquid is fully contacted, and the dust in the flue gas is trapped in the washing liquid under the combined effect of collision, inertia, convection, diffusion and purification mechanisms. The SO2 gas in the flue gas undergoes sufficient neutralization reaction with the alkaline washing solution, resulting in the formation of sulfite. Then, as the water flows from the bottom pipeline of the desulfurization and dust collector into the sedimentation tank. At this point, most of the smoke and SO2 have been removed, and the flue gas carrying a lot of water enters the cyclone dehydrator. After dehydration, it is discharged through the chimney by the induced draft fan. The water and some of the smoke and dust that come down from the cyclone flow into the sedimentation tank from the bottom of the cyclone dehydrator. The operation process of a cyclone dust collector: The cyclone dust collector is a dust removal device that uses the centrifugal force generated by the rotating airflow to separate dust particles from the dust collection airflow. It has the advantages of simple structure, small volume, unnecessary accessory equipment, low cost, moderate resistance, no moving parts inside the device, and easy operation and maintenance. Cyclone dust collectors are generally used to capture particles larger than 5-15 μ m, with a dust removal efficiency of over 80%. In recent years, improved cyclone dust collectors have achieved a dust removal efficiency of over 5%. The disadvantage of a cyclone dust collector is its low efficiency in capturing particles smaller than 5 μ m. Overview of the movement of airflow and dust particles in a cyclone dust collector: The majority of the rotating airflow moves along the wall of the cyclone in a spiral shape from top to bottom towards the bottom of the cone, forming a descending external rotating dusty airflow. The centrifugal force generated during the strong rotation process throws dust particles with much higher density than the gas towards the wall. Once the dust particles come into contact with the wall, they lose their inertial force and fall down along the wall into the ash hopper by the momentum of the inlet velocity and their own gravity. The rotating downward airflow reaches the bottom of the cone and then turns upwards along the axis of the dust collector to form an upward internal rotating airflow, which is discharged from the exhaust pipe of the dust collector. Another small portion of the airflow entering from the air inlet flows towards the top cover of the cyclone dust collector, and then flows downwards along the outer side of the exhaust pipe. When it reaches the lower end of the exhaust pipe, it reverses direction and is discharged from the diffuser pipe along with the rising central airflow, and the dispersed dust particles are also carried away.
