Abstract

The invention discloses a pre-charge spraying desulfurization and dust removal device which is applied to the technical field of coal-fired flue gas desulfurization and dust removal. The pre-charge spraying desulfurization and dust removal device comprises a tower body, wherein the bottom of the tower body is connected with a gas inlet pipe and a liquid outlet pipe, and the top of the tower body is connected with a gas exhaust pipe correspondingly; a plurality of spraying heads are arranged in the tower body; a pre-charge needle is arranged at the front end of each spraying head and is connected with a high-voltage power supply through a cable; a high-pressure air pipeline is connected to a spraying pipe of the spraying heads and is connected with a high-pressure air compressor; the spraying heads are connected with an absorption liquid pipeline; a valve is arranged on the absorption liquid pipeline and is connected with an absorption liquid conveying pump; the absorption liquid conveying pump is connected with an absorption liquid preparation pool through a pipeline; a demister is arranged above the spraying heads. The pre-charge spraying desulfurization and dust removal device can be used for synchronously removing sulfur dioxide and fine particulate matters in coal-fired flue gas, and is high in efficiency and low in cost.

Description

technical field [0001] The invention belongs to the technical field of coal-fired flue gas purification, and in particular relates to a pre-charged electric spray desulfurization and dust removal device. Background technique [0002] As we all know, my country is a country that uses coal as its main energy source, and its annual coal consumption has exceeded 3.5 billion tons. The resulting sulfur dioxide and dust pollution are very serious. As one of the areas with the highest fine particulate matter in the world, the pollution of fine particulate matter in my country has attracted great attention from the society. Therefore, fine particulate matter will become the main task of air pollution control in the next few years, and its technology research and development and application promotion will become the field of atmospheric environmental protection. one of the most important jobs. [0003] At present, the removal of particulate matter in coal-fired flue gas mainly relies ...
