Embodiment 1

[0056] This embodiment provides a dust removal and mist removal device, which includes a single dust removal and mist removal assembly. The dust removal and mist removal assembly includes a plurality of dust removal and mist removal components 1 arranged at intervals, wherein the cross section of the dust removal and mist removal component 1 includes half Wavelength sine wave curve or cosine wave curve (see Figure 7 ). These dust removal and mist removal components 1 include a first group 100 and a second group 200. The dust removal and mist removal components 1 in each group are arranged in the same direction, that is, the crests and troughs are all facing the same direction, such as figure 1 with 2 As shown, the first group 100 and the second group 200 are arranged in opposite directions, and are arranged axisymmetrically with each other, and the connection line of the two sets of dust removal and mist removal components is taken as the symmetry axis. Therefore, at the juncti...

Embodiment 2

[0061] This embodiment provides a dust removal and mist removal device, which is different from Embodiment 1 in that it includes at least two dust removal and mist removal components, such as a first dust removal and mist removal assembly 300 and a second dust removal and mist removal assembly 400, each The dust removal and mist removal components 1 in the fog assembly are arranged in the same direction, that is, the crests and troughs are all facing the same direction, such as Figure 3~5 As shown, the first dust-removing and mist-removing assembly 300 and the second dust-removing and mist-removing assembly 400 are arranged axially symmetrically, and the vertical end plate at the junction of the first dust-removing and mist-removing assembly 300 and the second dust-removing and mist-removing assembly 400 is the axis of symmetry. .

[0062] The width of the first dust and mist assembly 300 and the second dust and mist assembly 400 are the same (e.g. Figure 3~5 ), can also be di...

Embodiment 3

[0067] This embodiment provides a dust removal and mist removal system, which includes at least one dust removal and mist removal device 500 of any one of the foregoing Embodiment 1 and Embodiment 2, which may be a combination of multiple dust removal and mist removal devices 500. The dust removal and mist removal device 500 of this embodiment is installed in an absorption tower and / or a horizontal flue.

[0068] Such as Picture 12 As shown, the dust removal and mist removal device 500 in the system is installed in an absorption tower, and a plurality of dust removal and mist removal devices 500 form a "one" shape. Each dust removal and mist removal device 500 has a first plane, and the first plane is connected to the flue gas. The angle of the flow direction is 90°. The arrow 13 in the figure shows the direction of the flue gas flow.

[0069] Such as Figure 13 As shown, the dust removal and mist removal device 500 in the system is installed in the absorption tower, and multiple...

Abstract

The invention discloses a dedusting and demisting device. The dedusting and demisting device includes multiple dedusting and demisting parts arranged according to spacing, wherein at least two dedusting and demisting parts are arranged in an axisymmetric manner, and so one or a group of the dedusting and demisting parts can compensate or partially compensate for force generated by the other dedusting and demisting parts. The invention also discloses a dedusting and demisting system comprising at least one the dedusting and demisting device. The dedusting and demisting device and system can effectively prevent collapse of the device caused by inclination-to-one-side of the multiple dedusting and demisting parts connected internally in a span of the dedusting and demisting device, thereby improving the structure stability and demisting performance of the dedusting and demisting device and system. The dedusting and demisting device and system is simple in structure and can meet high requirements of dedusting and demisting emission standards.

Description

Technical field [0001] The invention relates to a gas-liquid separation technology, belonging to the field of flue gas desulfurization and environmental protection, in particular to a dust removal and mist removal device and a dust removal and mist removal system. Background technique [0002] As the current requirements for the emission standards of air pollutants for coal-fired generating sets have increased, the design of the main components of the mist eliminator and the integrated device for dust and mist has been diversified. The dedusting and mist removal device with corrugated board as the main component is still the mainstream configuration. The structure of the corrugated board has also changed from a single-curved flow channel to a multi-curved flow channel. The structure of the demister has also been optimized from a single layer to a single pitch, and is optimized according to the flow field. Differential layout of uneven design; The design of the demister has also c...
