Integrated horizontal wet-process desulfurizing device

Abstract

The invention discloses an integrated horizontal wet-process desulfurizing device, belonging to the field of environmental engineering. The device comprises a smoke inlet, a spray region, a slurry region, a shower pipe, a circulating slurry pump, a desulfurizing nozzle, a pneumatic jetting gun, a hybrid functional region, a slurry lifting pump, a pull cabinet type defogger, a backwash water system and a chimney. The device adopts an integrated design, the hybrid functional region is arranged on the right lower side of the slurry region, and the slurry region, a new material feeding region and a clarifying and concentrating region are integrated in the hybrid functional region, so that the floor space is reduced, the distance between the regions is reduced as well and the energy is greatly saved. In the device, the shower pipe, the circulating slurry pump and the defogger are all designed as components which can be replaced without shutdown and are installed outside the desulfurizing device. The bottom surface of the slurry region is designed to have the shape of a bevel and is provided with the pneumatic jetting gun so that sedimentation phenomenon of slag materials at the bottom is effectively prevented and power consumption is reduced. The device disclosed by the invention has the advantages of low investment, small floor space, few damages caused by pressing, no shutdown type overhauling, full spray coverage, high desulfurization efficiency and wide application range.

Description

technical field [0001] The invention belongs to the field of environmental engineering and relates to a novel integrated horizontal wet desulfurization device. Background technique [0002] The "Twelfth Five-Year Plan" of the Ministry of Environmental Protection has formulated the total amount control target of sulfur dioxide. By 2015, the total emission of sulfur dioxide will be reduced by 10% compared with 2010. At present, the wet flue gas desulfurization technology has been widely used in desulfurization devices in the electric power, chemical industry, and metallurgical industries. Although this method has a wide range of applications, the desulfurization efficiency can reach more than 90%. [0003] At present, the common wet desulfurization devices at home and abroad adopt vertical spray towers, which have the characteristics of excessive dust concentration at the outlet, floating gypsum rain, large wastewater treatment capacity, high system pressure loss, high operat...
