Description

Technical Field

[0001] The utility model relates to the technical field of roller kiln waste gas treatment, in particular to an integrated desulfurization and dust removal device. Background Art

[0002] The desulfurization dust collector is a professional desulfurization equipment with turbocharged turbulent dust removal and desulfurization technology. Its working principle is: under the action of the turbocharged turbulent device, the sulfur-containing gas is in a state of high-speed rotation and diffusion with the enhanced turbulent mass transfer formed by the absorption slurry. The mass transfer process is to form an emulsion layer between the gas and the liquid, which not only makes the chemical absorption and neutralization fast, but also keeps the liquid film close to neutrality, and can maintain a very high and stable mass transfer rate throughout the process. Therefore, it is an excellent low-resistance and high-efficiency desulfurization equipment. The turbocharged turbulent mass transfer desulfurization equipment technology belongs to the third generation of high-tech products. The core technology is: based on the theory of permeable surface renewal, based on the strong mass transfer mechanism of multiple turbulent mixing, it is a high-tech technology that uses liquid as a separation agent to separate dispersed dust particles, smoke and harmful gases from gas, air or exhaust gas and achieve the purpose of purification, and has the advantages of simultaneous dust removal and desulfurization. Its technical characteristics are: integrated dust removal and desulfurization, low energy consumption, small footprint, simple operation, significant efficiency, low operating cost, no blockage and scaling, stable system operation, low pressure resistance loss, and applicable to various sulfur-fixing agents. It is at the leading level in wet dust removal and desulfurization process technology at home and abroad. And in the application of coal-fired industrial boilers, it has achieved zero emission results. Desulfurization equipment is widely used in the desulfurization and dust removal industry of coal-fired boilers. It can be wet dust removal, wet desulfurization, or integrated dust removal, desulfurization and dust removal. It is not only suitable for dust removal and desulfurization of coal-fired circulating fluidized bed boilers in power plants, but also can be used for wet desulfurization and dust removal and flue gas purification of coal-fired chain boilers. It has high efficiency in removing sulfur dioxide and thorough tail gas purification. It is used in the furnace industry to remove hydrogen fluoride and kiln tail gas acid waste gas purification equipment, etc., and desulfurizes pellet and sintering machine tail gas. The desulfurizer has a very high purification efficiency of waste ammonia water. The original flue gas SO2 is removed from 11000mg / m3 to below 120mg / m3, and is widely used in the field of pellet flue gas in steel plants. It is a low-resistance and high-efficiency wet dust removal and desulfurization equipment and a novel desulfurization equipment environmentally friendly product. The dust collector is a device used to remove harmful dust in the gas phase. On this basis, the desulfurization effect is increased, which is a desulfurization dust collector. Desulfurization dust collectors are generally wet desulfurization dust collectors. Wet desulfurization dust collectors include water film desulfurization dust collectors, impact water bath desulfurization dust collectors, etc.
