Single-tower six-section stepped purification desulfurization dust-removal and ultralow-emission integrated device

Abstract

The invention discloses a single-tower six-section stepped purification desulfurization dust-removal and ultralow-emission integrated device, and belongs to the field of environmental protection; the device is composed of an oxidation section, a concentration section, an absorption section, a purification water-washing section, a demisting section, a separation plate and a wet electric section. The upper part of the oxidation section of the device achieves gas communication with the concentration section through a pipeline, and liquid separation is achieved by the separation plate; the upper part of the concentration section of the device achieves gas communication and liquid separation with the absorption section through a liquid collecting tank; the upper part of the absorption section of the device achieves gas communication and liquid separation with the purification section through a liquid collecting tank; the demisting section of the device is located at the upper part of the purification section; the wet electric section of the device is located at the upper part of the demisting section. A reaction in the single-tower six-section stepped purification desulfurization dust-removal and ultralow-emission integrated device is a gas-liquid reaction, the reaction speed is fast, the reaction is completed, and the desulfurization efficiency is high. The system realizes the requirement of ultralow emission, and is simple and concise in structure, easy to implement, low in cost, and favorable for wide popularization and utilization.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a single-tower six-stage cascade purification, desulfurization and dust removal integrated device with ultra-low emissions. Background technique [0002] my country is a big coal-producing and coal-burning country in the world. Energy and environment are the two major themes of today's development, which are closely linked and contradictory. [0003] Sulfur dioxide produced by coal combustion, this gas dissolves into acid rain when encountering rain and snow at high altitudes, can lead to the death of large areas of animals and plants, bring great damage to the ecological environment, and can also corrode industrial production equipment, bringing economic losses. big impact. There are many ways to control sulfur dioxide in flue gas: fuel desulfurization before combustion, desulfurization during combustion of desulfurizers, and flue gas desulfurization after combustion. J...
