Detailed Description
The invention will be further explained with reference to the drawings and the examples.
Fig. 1 shows an embodiment of a marine desulfurization apparatus with a water retaining structure, which includes a tower body 1, a water shower 2, a water retainer 3, an air inlet 4, a drain port 5, and an air outlet 6. The tower body 1 is a main body component of the marine desulfurization device, the component is a vertically arranged barrel, an axial air inlet 4 is arranged in the middle of the bottom of the tower body 1, and an air outlet 6 reserved on the upper part and the air inlet 4 are on the same axis. The upper part of the inner cavity of the tower body 1 is provided with a water drenching device 2 which sprays washing water downwards, one side of the bottom is provided with a drainage port 5 which penetrates through the outer wall of the tower body 1, and the falling washing water is discharged from the drainage port. The gas inlet 4 leads the exhausted waste gas from the flue of the main machine to contact with the fallen washing water, and SO in the exhausted waste gas is removed through chemical combination reaction2. In the embodiment, the tower body 1 is arranged on the main machine, the air inlet 4 of the tower body is in butt joint with the flue of the main machine, in order to prevent washing water falling from the upper part from entering the air inlet 4, the water retaining device 3 is arranged in the inner cavity of the tower body 1, the water retaining device 3 arranged between the water drenching device 2 and the pipe orifice at the upper end of the air inlet 4 does not reduce the water drenching amount, does not influence the rising of waste gas, and finally does not reduce the original desulfurization efficiency. The water retaining device 3 comprises an upper frame edge 3.1, ribs 3.2 and a bottom plate 3.3, the diameter value of the outer wall of the annular upper frame edge 3.1 is equal to the diameter value phi 1 of the inner wall of the tower body 1, the upper frame edge 3.1 is connected to the inner wall of the middle section of the tower body 1, and the connecting structure is of a detachable structure and is convenient for later normal maintenance. The disc-shaped bottom plate 3.3 is open downwards, and the inverted bottom plate 3.3 covers the air inlet 4 like an open umbrella so as to prevent the sprayed washing water from splashing into the air inlet 4. The power of the main engine matched with the present embodiment is 6500kw, and the exhaust gas displacement is 45864 kg/hr. In order to ensure the effective shielding of the air inlet 4 by the bottom plate 3.3, the diameter of the open end of the bottom plate 3.3 must be larger than that of the air inlet 4, and in this embodiment, the diameter of the open end of the bottom plate 3.3 is 150mm larger than that of the air inlet 4 because the power of the host is centered. The bottom plate 3.3 arranged below the upper frame edge 3.1 is connected with ribs 3.2 alternately, the bottom plate 3.3 forming the water eliminator 3 is suspended above the upward pipe orifice of the air inlet 4The mounting structure of (1). In order to ensure the stable position of the suspended bottom plate 3.3, the ribs 3.2 must be provided with sufficient rigidity, the ribs 3.2 are made of stainless steel plates with the thickness of 5mm, and the width of the ribs 3.2 is 75 mm. The mounting position of the water eliminator 3 in the structure is important, the desulfurization efficiency is reduced due to overhigh and overlow positions, and in the embodiment, the numerical value of the vertical distance H of the bottom plate 3.3 of the water eliminator 3 relative to the upper port of the air inlet 4 is determined according to the radius value of the air inlet 4. The space section area larger than the cross section area of the air inlet 4 is reserved at the interval, so that smooth air flow can be ensured, the washing water can not fall freely, and most importantly, the desulfurization efficiency is not reduced after the waterproof structure is added. Because the water retaining device 3 effectively prevents the washing water from entering the air inlet 4, the matched main machine flue does not have the accident of washing water erosion, thereby greatly reducing the maintenance cost. In addition, no washing water penetrates into the channel during the operation of the main machine, and a flameout accident can never occur.
