Embodiment example 1

[0029] see Figure 1-7 , a high-efficiency flue gas desulfurization and dust removal purification device, the device includes a desulfurization tower, a dust removal box and a purification box, characterized in that the desulfurization tower includes an inner tower and an outer tower;

[0030] The outer tower is cylindrical, and the outer tower is provided with a flue gas inlet along the tangent direction of the tower wall and penetrating the tower wall. The direction of the tangent of the four liquid nozzles on the outer tower wall is the same as the tangent direction of the flue gas inlet, and the installation position of the liquid nozzle here is equal to the center line of the flue gas inlet. It is conducive to the full mixing and contact of the liquid medicine and the flue gas; the inner surface of the outer tower wall is provided with an inverted conical wall that protrudes toward the center of the outer tower, and the inverted conical wall is located above the flue gas ...

Abstract

The invention relates to a high-efficiency smoke desulfurizing, dedusting and purifying device. The device comprises a desulfurization tower, a dedusting box and a purifying box, smoke enters the desulfurization tower, the smoke and a chemical liquid flow in the desulfurization tower in the same direction and undergo a desulfurization reaction and rotation in order to achieve preliminary dedusting, radial interlacing mixing is performed on a stop channel, and a fluid infusion is obtained in the central area of the tower, so full air and liquid mixing, complete contact reaction and good desulfurizing and dedusting effects are achieved; the arrangement of a filter plate and an activated carbon adsorption layer makes waste gas filtered and adsorbed and some large particulate impurities in air filtered out, the waste gas in the dedusting box is conveyed into the purifying box through an exhaust fan and a conveying tube, the contact between an air filter screen and the chemical liquid makes the waste gas in full contact with the chemical liquid at the bottom of the inner chamber of the purifying box in order to chemically react the waste gas, and a stirrer in the purifying box can stir the chemical liquid to improve the reaction efficiency of the waste gas and the chemical liquid and improve the waste gas purifying effect.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an efficient flue gas desulfurization and dust removal purification device. Background technique [0002] A power plant is a factory that converts various primary energies stored in nature into electrical energy. There are many ways to generate power in power plants today: thermal power plants that rely on thermal power, hydropower plants that rely on hydropower, and solar (photovoltaic) and wind power. Power plants with tidal power generation are called coal-fired power plants that use coal as fuel to generate electricity. During the combustion of coal-fired fuel, a large amount of toxic and harmful gases will be produced. The gas contains a large amount of dust and sulfur compounds, which are directly discharged into the atmosphere. It will cause air pollution, so it is necessary to use dust removal and desulfurization devices to purify the flue gas discharged ...
