Desulfurization dust remover

Abstract

The invention belongs to the technical field of environment protection and relates to a dust removing equipment structure, in particular to a desulfurization dust remover which is widely applied to drying equipment taking fuel coal as a heat source. The desulfurization dust remover comprises a smoke path and an alkali liquor path, wherein the smoke path comprises a pre-spraying smoke pipeline (1), a vertical barrel reaction tank (2), a post-spraying smoke pipeline (3), a smoke guide draught fan (7) and a chimney (8); the alkali liquor path comprises an antiseptic sewage pump (4), a liquid spraying pipeline system (5) and an alkali liquor tank (6). The smoke enters the vertical barrel reaction tank (2) in a tangential manner and spirally rises in the vertical barrel reaction tank (2), so that the staying time of the smoke in the vertical barrel reaction tank (2) is longer. At the same time, the staying time of atomized alkali liquor in the vertical barrel reaction tank (2) is also longer. The desulfurization dust remover has the effects of saving the resources and reducing the cost, and the whole system basically has no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a desulfurization and dust removal equipment structure, in particular to a desulfurization and dust removal device. The desulfurization dust collector is widely used in drying equipment that uses coal as the heat source. Background technique [0002] China today has very strict requirements on flue gas emissions. However, most of the heat sources selected by the agricultural product drying industry are still coal-fired. However, the problem with coal combustion is that the flue gas released during the combustion process will bring heavily polluted. In order to allow farmers to use cheap coal and protect the atmospheric environment, the patent applicant has designed a small desulfurization and dust collector specially matched with small-scale coal-fired drying equipment for agricultural products. [0003] Before the existing desulfurization and dust collector is s...

Problems solved by technology

[0002] China today has very strict requirements on flue gas emissions. However, most of the heat sources selected by the agricultural product drying industry are still coal-fired. However, the problem with coal combustion is that the flue gas released during the combustion process will bring severe pollution

[0003] Before the existing desulfurization and dust collector is sprayed, the flue gas pipe enters the vertical cylinder reaction tank in a radial way. This way of entry makes the flue gas enter the reaction tank, turn upwards and then be discharged directly, resulting in the flue gas in the reaction tank. The residence time is short, the overall contact time between flue gas and atomized lye is short, and the reaction time is not enough

At the same time, after the lye is atomized, the contact with the flue gas is not sufficient, resulting in incomplete reaction

In addition, there is still a dead angle that cannot be touched by the atomized lye and the flue gas
