Problems solved by technology

However, the wet electrostatic precipitator is placed behind the desulfurization tower, which will increase resistance. It uses closed-loop flushing water, which needs to continuously replenish raw water and discharge waste water, which increases the difficulty of water balance in the desulfurization system. The technical cost of a single product of the wet electrostatic precipitator High, the equipment investment cost is higher than that of ordinary electrostatic precipitators, and in addition to the power consumption of the dust collector itself, the auxiliary circulating water pump will also consume part of the electricity during operation, and the additives in the flushing water will also increase part of the operating cost, so its input and operating costs are too expensive

Abstract

The invention discloses a dedusting and demisting device, a treatment tower and a use of the dedusting and demisting device. The dedusting and demisting device comprises a guide cylinder, a middle shaft and a rotating blade group located in the guide cylinder, and a retaining ring arranged at the upper part of the guide cylinder. The rotating blade group comprises a center cylinder, a blade group and an outer cylinder. The rotating blade group is located in the guide cylinder. The middle shaft sleeves the center cylinder. The center cylinder and the outer cylinder are arranged coaxially. The blade group comprises multiple blades. One end of each one of the blades is fixedly connected to the center cylinder and the other end is fixedly connected to the outer cylinder. The blades are inclinedly arranged and have elevation angles of 20-60 degrees. The dedusting and demisting device can completely replace the conventional demister in the existing desulfurization tower and a wet type electric precipitator in the rear of the desulfurization tower, has excellent dedusting and demisting effects and reduces equipment and operation costs.

Description

technical field [0001] The invention relates to a dust and fog removal device, a processing tower and its use, in particular to a dust and fog removal device, a flue gas treatment tower and its use for dust and mist-laden flue gas after dust removal and desulfurization. Background technique [0002] China is a large coal-based energy consumer, but also a major steel producer. A large amount of dust, sulfur dioxide, nitrogen oxides and other harmful substances will be produced in the process of coal burning and smelting. If the dust is not treated, it will enter the atmosphere with the flue gas, seriously affecting the visibility and air quality of the atmosphere, and sulfur dioxide is even more harmful. [0003] At present, the dust removal technologies applied to coal-fired power plants and sintering machines are mainly electrostatic dust removal and bag dust removal. The electrostatic dust removal efficiency is greater than 10, and the dust removal efficiency of the corre...
