Problems solved by technology

The above-mentioned wet desulfurization technology includes flue gas desulfurization, desulfurization wastewater oxidation treatment or regeneration unit. The process is long, there are many equipments, and the floor area is large, which seriously restricts the construction and upgrading of dust removal and desulfurization devices. Some devices and boilers are due to lack of There is not enough space to upgrade and renovate, resulting in smoke emission indicators that cannot meet the current national standards and forced to stop work or demolish and rebuild

Abstract

The invention discloses a desulfurization device and a flue gas dust removal, desulfurization and wastewater treatment method. The desulfurization device comprises a pretreatment unit, a deep treatment unit and a wastewater treatment unit, wherein the pretreatment unit is provided with a venturi pipe, the venturi pipe tube comprises a contraction section, a throat tube, a diffusion section and a plurality of groups of liquid-phase spraying nozzles arranged in parallel to the axial direction, each group comprises two liquid-phase spraying nozzles with opposite spraying nozzle directions, and the two liquid-phase spraying nozzles are respectively arranged at the tail end of the contraction section and the starting end of the diffusion section. According to the invention, the desulfurizationdevice integrates the functions of flue gas dust removal, desulfurization and wastewater treatment, greatly reduces the occupied area, remarkably reduces the cost required for device construction andtransformation and the operation cost of the device, and reduces the content of the soluble salt in the discharged flue gas, wherein the discharged flue gas meets the ultra-clean emission standard.

Description

Technical field [0001] The invention belongs to the field of industrial waste gas purification, and relates to a desulfurization device and a flue gas dust removal, desulfurization and wastewater treatment method. Background technique [0002] Boiler flue gas and flue gas discharged from factories contain sulfur dioxide and dust. Both sulfur dioxide and dust are the main components of air pollutants. Sulfur dioxide is the main cause of acid rain. Dust with a smaller particle size is the main culprit for the formation of haze. One. [0003] Wet desulfurization has the advantages of high desulfurization rate, reliable operation of the device, and simple operation. Therefore, the existing flue gas desulfurization technologies in various countries in the world are mainly wet desulfurization. Traditional wet desulfurization technologies mainly include limestone-gypsum method, double-alkali desulfurization, sodium-alkali desulfurization, and ammonia desulfurization. The above-mentioned...
