Problems solved by technology

However, the wet desulfurization process system is complex, with a large initial investment, a long construction period, and high operating costs, especially the serious consumption of water resources.
The voice of replacing wet method with dry method is getting stronger and stronger in the industry. Limited by the problem of low desulfurization efficiency of existing dry method, scientific and technical personnel are actively carrying out research on improving the efficiency of dry method desulfurization

Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] See figure 1 This figure is a schematic diagram of the overall structure of the dry flue gas desulfurization device of the embodiment. It should be understood that the device is arranged on the system flue gas discharge path to achieve the functional requirement of full flue gas desulfurization.

[0036] Such as figure 1 As shown, the dry flue gas desulfurization device includes a casing 1 for constructing a flue gas flow path, and a charged desulfurization zone 2 and a fixed-bed desulfurization zone 3 arranged in the casing 1. It should be noted that in order to clearly show the main components of the device and its relative positional relationship, figure 1 Use perspective sketches to illustrate the necessary internal c...

Abstract

The invention discloses a dry smoke desulfurization device. The dry smoke desulfurization device comprises a device shell provided with a smoke inlet and an outlet, an electrical charge desulfurization area and a fixing bed desulfurization area, and the smoke inlet of the device shell is provided with a desulfurizer supply opening; the electrical charge desulfurization area is arranged at the upstream side in the device shell, and an anode part of the electrical charge desulfurization area is spaced with a cathode part to conveniently charge the desulfurizer in the electrical charge desulfurization area and desulfurize smoke for the first time; the fixing bed desulfurization area is arranged at the downstream side in the device shell and is provided with several desulfurization bags to conveniently deposit the desulfurizer on the surface of the desulfurization bags. The desulfurization efficiency can be greatly improved, and on the basis of effectively controlling the device investmentcost and running cost, it is ensured that smoke exhaust meets environmental protection requirements.

Description

Technical field [0001] The invention relates to the technical field of flue gas environmental protection treatment, in particular to a dry flue gas desulfurization device. Background technique [0002] At present, the contradictions between economic and social development and resource and environmental constraints are becoming increasingly prominent, and environmental protection is facing increasingly severe challenges. As we all know, dust and harmful gases from fuel combustion in industrial kilns, thermal power, cement, steel and other industrial production processes are discharged into the atmosphere, which is one of the main factors causing air pollution. Therefore, purification of harmful pollutants in the industrial production process is the main measure to prevent air pollution and improve environmental quality. For example, desulfurization equipment is an important environmental protection equipment widely used. [0003] There are three types of flue gas desulfurization: ...
