Blockage at the flue gas outlet of the marble desulfurization tower

2016-04-24View Original

Thread Content

Hello, experts. Our factory’s boilers use wet flue gas desulfurization. Due to the poor efficiency of electrostatic dust removal, blockages often occur at the outlet of the auxiliary flue gas tower for desulfurization (at the point where it meets the flue duct). Moreover, this type of ash is very hard and difficult to clean. Is there any effective way to prevent ash from accumulating at this outlet?

What kind of ore is marble, and what is its principle? _?

It seems that marble is used as the material for desulfurization towers; wet processes generally use fiberglass. What are the advantages of marble?

A type of granite; double-alkali wet desulfurization method

What kind of coal do you use, and what is its sulfur content? The problem can be solved at its source by using the method of vaporized combustion of carbon molecules. Moreover, the costs of environmental protection measures can be significantly reduced, typically by 80%.

If, after the use of wet flue gas desulfurization and electrostatic dust removal in the boiler’s flue gas treatment system, no dust particles are still present at the flue gas outlet, it can be inferred that the current desulfurization efficiency also requires attention. The wet flue gas desulfurization method inherently washes away and separates a portion of the flue gas dust while carrying out desulfurization. If the designed gas velocity is much lower than the actual operating gas velocity, not only will the desulfurization efficiency be unsatisfactory, but the gas flow will also carry both the primary dust present in the flue gas and the secondary dust formed by the desulfurization slurry downstream. If the downstream dust removal equipment consists only of electrostatic dust collectors, it will inevitably be unable to handle such operational loads. Electrostatic dust removal has frequently shown its inadequacy for actual operating conditions in the application of flue gas desulfurization, denitration, and dust removal in power plants. Those familiar with electrostatic dust removal equipment know that this technology imposes strict requirements on the types of particles carried by the airflow, as well as on the size distribution of those particles in the airflow ; Otherwise, the operational efficiency is not satisfactory, and the operating costs are high. If wet flue gas desulfurization is used, under the basic spraying and washing conditions of the desulfurization slurry, the gas stream exiting the desulfurization stage mainly contains liquid droplets, tiny droplets of liquid, and a very small amount of dust. Under these operating conditions, electrostatic dust removal technology can be employed; when combined with dynamic gas-solid separation techniques such as the vaned high-efficiency gas-liquid separation method and multi-factor swirl separator technologies, it is possible to use dynamic separators with low operating costs to remove the vast majority of droplets and particulates carried in the airflow in advance ; Let the subsequent electrostatic dust removal equipment capture the remaining, very small particles. This separation technology, which combines a \"dynamic separator\" with electrostatic dust removal, ensures smoother system operation, lower operational and maintenance costs, and better exhaust gas parameters.
