Abstract

The invention relates to a high-efficiency pneumatic pipe bundle phase-change dedusting and demisting device and application. The device comprises a hollow barrel with two ends open, an upper barrel sealing plate, a lower barrel sealing plate, rotational flow sections, pipe-bundle-type water mist distribution sections and a water retaining section, the rotational flow sections of more than two stages are arranged coaxially in the inner-layer barrel from bottom to top at intervals, each pipe-bundle-type water mist distribution section is arranged coaxially between each two corresponding rotational flow sections, and the water retaining section is coaxially arranged on the inner-layer barrel below the upper barrel sealing plate in an outer-edge-sealed manner. The device can effectively remove liquid drops, dust and superfine dust of smoke systems or industrial waste gas systems, is good in demisting and dedusting effect and is lower in energy consumption and more energy saving when compared with wet-type electric dedusting. In addition, by the device, arrangement space is saved, and power equipment is omitted; the device has good dedusting and demisting effect while energy consumption is lowered, and can be applied to dedusting and demisting of industrial tail gas.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry and environmental protection, and relates to a dust and fog removal device, in particular to a high-efficiency pneumatic tube bundle phase change dust and fog removal device and its application. Background technique [0002] In recent years, with the gradual increase of my country's economic strength and stricter environmental protection standards, the implementation of near-zero emissions for major pollutant indicators requires dust emission indicators to be less than or equal to 10mg / Nm 3 . Conventional dust and mist removal devices are difficult to meet the requirements. [0003] For the treatment of dust, many methods are currently used, which is to remove large particles of dust before the desulfurization system, and perform secondary dust removal through the demisting device of the desulfurization system. The dust removal index can reach 50-30mg / Nm 3 . [0004] The demisting sy...
