Embodiment Construction

[0014] The parallel flow wet dust removal device of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] A dusty gas flow rate of 60000Nm 3 / h, the gas contains elemental sulfur dust, and the elemental sulfur content is 80mg / Nm 3 , particle size 3.2μm, operating pressure 0.55 ~ 0.6MPa. The gas containing elemental sulfur enters the tower body 1 of the co-current wet dedusting device through the inlet pipe 3 on the upper part of the dedusting device. The diameter of the tower body 1 of the co-current wet dedusting device used is 1500mm, and four cyclone mixers 2 are set. The blades of the first and third cyclone mixers are installed clockwise, the blades of the second and fourth cyclone mixers are installed counterclockwise, and the installation distance is 600mm. A pipe-type liquid distributor 5 is installed on the upper part of each cyclone mixer, and a circulation pump 8 and a regulating valve 10 are installed on the...

Abstract

The invention provides a parallel flow wet dust-collecting device and an operational method thereof. The dust-collecting device consists of a tower body, a whirlwind mixer, an air inlet pipe, a water inlet pipe, a liquid distributor, a water outlet pipe, a defogger, a circulating pump and a connecting pipeline. Air and washing water enter the whirlwind mixer in a mode of same direction and parallel flow, the air is fully mixed with and impacted by the washing water, the dust removed from the air is discharged from the bottom of the tower, and the clean air enters the defogger to remove the carried fogdrop and is discharged from an air outlet finally. The device has the characteristics of high dust-removing effect, small system resistance, no liquid flooding, small size of tower body and low water consumption, and can be applied to the process of washing and purifying various gases containing dust.

Description

technical field [0001] The invention relates to a gas purification technology, in particular to a co-current wet dedusting device for industrial dust-containing gas, which belongs to the field of dust-containing gas purification. Background technique [0002] In chemical, pharmaceutical, food, waste gas treatment, environmental protection and other fields, it is often necessary to purify dusty gas. At present, the widely used dust removal equipment includes various tower wet dust collectors, cyclone dust collectors, gravity dust collectors, electric dust collectors, bag dust collectors, etc. The tower type wet dust collector often adopts the method of gas-liquid countercurrent flow. There are trays in the tower, and some do not install trays. They directly use the form of empty tower spraying. The tower body, the gas flow rate in the tower is limited, and liquid flooding is prone to occur when the gas flow rate is high, especially when the particle size of the dust particle...
