Dry desulfurization technology and complete system

Dry desulfurization technology and complete system

Henan Ruiguang Machinery specializes in the manufacture of dry desulfurization technology and desulfurization equipment. Sulfur dioxide is the main pollutant produced in the thermoelectric production process. According to the principle of "standard-compliant emissions" and total volume control, as well as the characteristics of circulating fluidized bed boilers, limestone desulfurization in the furnace is used to make sulfur dioxide react with calcium oxide to form calcium sulfate and the slag is discharged along with the slag. The desulfurizing agent adopts limestone powder with a particle diameter ≤ 3MM and a purity (calculated as CaO) of 51.01 ﹪. The furnace temperature is controlled around 840 ~ 900, and the desulfurization efficiency is above 90 ﹪.

At present, the flue gas emitted from various domestic coal-fired boilers contains a large amount of harmful gases such as dust and sulfur dioxide. Our factory conducted in-depth research on dry-enhanced desulfurization of pulverized coal furnaces and circulating fluidized bed furnaces in power plants. First, the preferred components of the desulfurizing agent were determined. The limestone calcium powder was sprayed into the furnace to enhance the reaction activity and improve the desulfurization efficiency. Desulfurized fly ash is also better recycled. Fly ash contains a large number of spherical particles with advantages such as good grain shape, high strength, and low density. It can be widely used in metallurgical building materials and other fields.

The dry desulfurization process is carried out in a completely dry state without liquid phase intervention. With the increasingly perfection of the dry desulfurization process, coupled with the simple dry process flow, low investment, low operating costs and other factors, the dry desulfurization process has been Began promotion and application in coal-fired power plants. The spraying of calcium in the furnace is to spray the dry calcium powder directly into the furnace of the boiler. The heat in the furnace will calcine the calcium powder into active CaO to react with SO2 in the flue gas to achieve better desulfurization.

Dry desulfurization technology and complete system

Features of dry desulfurization technology:  
(1) The system is simple, reliable, and easy to operate, and is suitable for the flue gas desulfurization of large, medium and small unit boilers and sintering machines;
(2) Small footprint, flexible layout, and low investment, not only suitable for SO2 treatment of new power plants, but also suitable for desulfurization transformation of old power plants;  
(3) High desulfurization efficiency (up to 99%), no need for anticorrosion;
(4) The equipment has the advantages of long service life and small maintenance.
