Embodiment 1

[0024] like figure 2 As shown, it is a schematic structural diagram of a two-layer pipe row imitation water-drop-shaped tube-type mist eliminator provided by the present invention, comprising two layers of parallel tube rows 1, and the tube row 1 is composed of uniformly arranged pipes 3 with water-drop-shaped cross-sections. The two ends of the tube row 1 are respectively supported on the plate 2. The spacing between each row of tube rows 1 is arbitrary.

[0025] like figure 1 As shown, the long axis B of the teardrop-shaped section of the pipe 3 having a teardrop-shaped section is twice the short axis A of the teardrop-shaped section, and the large circle C of the teardrop-shaped section is 1.3 times the small circle D of the teardrop-shaped section. The head of the small circle D of the teardrop-shaped section has a wedge with a taper of 35°, and the inclination a of the pipe 3 is 9°.

Embodiment 2

[0027] like image 3 As shown, it is a schematic structural diagram of a water-drop-shaped tubular mist eliminator provided by the present invention with a three-layer tube row. There are three layers, and the other structures are the same as in Example 1.

Embodiment 3

[0029] like Figure 4A As shown, in order to use the demisting device of the above-mentioned imitation water-drop-shaped tubular mist eliminator, the imitation water-drop-shaped tubular mist eliminator 5 is arranged in the upstream position of the flue gas desulfurization tower or the horizontal flue, and is located in the flue gas desulfurization tower or the horizontal flue. A flat-plate mist eliminator 6 is arranged at the downstream position of the channel.

[0030] like Figure 4B As shown, the flushing water pipes 10 of the water-drop-shaped tubular mist eliminator 5 and the flat-plate mist eliminator 6 are arranged upstream and downstream of the water-drop-shaped tubular mist eliminator 5, while the downstream of the water-drop-shaped tubular mist eliminator 5 It is necessary to arrange a flushing water pipe 10 to clean the blades of the flat-plate mist eliminator 6 .

[0031] The water-drop-shaped tubular mist eliminator 5 is upstream at the inlet end of the flue gas...

Abstract

The invention provides a drip-imitating tube-type demister, which is characterized by comprising at least two layers of parallel rows of tubes, wherein the rows of tubes are formed by tubes which are uniformly arrayed, the two ends of the rows of tubes are respectively supported on a plate, and the direction of flue gas flow is vertical to the direction of the short axis of the inner tubes of therow of tubes. The invention also provides a demister device, which is characterized by comprising the drip-imitating tube-type demister, wherein the drip-imitating tube-type demister is arranged at aflue gas desulfurization tower or the upstream of a horizontal flue, the demister is arranged at the downstream of the flue gas desulfurization tower, or a vane demister is arranged at the downstreamof the horizontal flue. The invention has the advantages that the demister reduces partial flow resistance, the area for blocking mist drop can be enlarged, demisting effect is improved, and scale isnot easy to form.

Description

technical field [0001] The invention relates to a water droplet-like tube for a tubular mist eliminator, which is used for purifying flue gas in a flue gas desulfurization tower or a horizontal flue, and belongs to the technical field of flue gas purification devices. Background technique [0002] The Chinese utility model patent with the patent number of ZL200920286171.X discloses a tubular mist eliminator and a mist eliminator. In the above-mentioned patent, the tube type mist eliminator includes at least two layers of parallel tube rows. The tube row is composed of evenly arranged tubes. The two ends of the tube row are respectively supported on the plate. The direction of the smoke flow is the same as that of the tubes in the tube row. The axis direction is perpendicular. The demisting device includes the above-mentioned tubular mist eliminator. The tubular mist eliminator is arranged at the upstream position of the flue gas desulfurization tower or the horizontal flue....
