Problems solved by technology

[0004] The continuous automatic operation of the desulfurization tower cannot be realized in the existing moving bed device. At the same time, the desulfurization agent bed does not involve leakage prevention, which will increase the loss of desulfurization agent and cause blockage of the desulfurization tower. At the same time, the desulfurization tower has a certain dead volume, which cannot Realize the effective utilization of desulfurization agent, without the effect of dust removal and whitening

Abstract

The invention provides a moving bed device and process for dry flue gas desulfurization. The moving bed device comprises a desulfurizing agent feeding unit, the desulfurizing agent conveying unit is connected with the desulfurizing agent feeding unit so as to convey a desulfurizing agent; the desulfurizing tower is provided with a flue gas inlet, a flue gas outlet, a desulfurizing agent feeding port and a desulfurizing agent discharging port, a partition blind plate is arranged between the flue gas inlet and the flue gas outlet, and the desulfurizing agent feeding port is connected with the desulfurizing agent conveying unit. Efficient utilization of the desulfurizing agent is realized through recycling of the desulfurizing agent; no wastewater or solid waste is generated, the pressure drop, the temperature drop and the occupied area are small, the energy consumption is low, dust and white can be removed, and green treatment of SOx is realized; the operation process is simple and the investment and operation cost is low.

Description

technical field [0001] The invention relates to the technical field of dry desulfurization devices for sulfur-containing tail gas, in particular to a moving bed device and process for dry flue gas desulfurization. Background technique [0002] SOx is one of the most important air pollutants at present. As the most important energy source in my country, the combustion of coal will produce a large amount of SOx. At present, the relatively mature desulfurization processes in China mainly include wet desulfurization, semi-dry desulfurization and dry desulfurization. Wet desulfurization has high efficiency and low operating cost, but it is easy to generate waste water, and the flue gas temperature drops. A moving bed device and process for dry flue gas desulfurization has large gas resistance. Semi-dry desulfurization has the characteristics of both dry and wet desulfurization. The adsorption of SOx is realized by spraying desulfurizer powder and water in the tower. The desulfu...
