Problems solved by technology

[0008] 2) At the same time, the scrubber uses a hollow fiber membrane contactor to realize the washing function, the pressure drop and resistance are very large, and a booster fan is added, and the energy consumption and cost of system operation are very high
The pressure loss of the bubbling washing method is the energy loss of the exhaust to overcome the liquid pressure, which basically corresponds to the liquid column pressure at the depth of the exhaust immersion in the liquid; that is to say, the better the washing effect, the greater the pressure loss and the higher the operating cost. High, the contradiction between washing effect and operating cost is basically irreconcilable
[0018] Under the condition of using seawater as the washing liquid, the technical scheme of the invention patent requires that the operating pressure loss is less than 6 inches (152 mm) of water column, and obviously the depth of the exhaust smoke immersed in the washing liquid is also less than 6 inches. With such a shallow immersion depth, Even if supplementary technical measures are taken to increase "mixing blades" to form turbulent flow and disperse air bubbles, the total liquid-gas contact area is extremely limited, and the washing and absorption rates are still very low; to significantly improve the washing effect, it is necessary to increase the immersion depth of the exhaust gas and add Large pressure loss, increased energy consumption and operating costs, the effect is obviously not good
[0019] 2) The contradiction between cooling high-temperature flue gas and low-temperature absorption of sulfur dioxide is difficult to overcome
The cooling, washing and absorption of high-temperature flue gas in this invention is mainly carr

Embodiment 1

[0086] Such as figure 1 As shown, the flue gas inlet 3.2 in the housing is fixed at the bottom of the housing 1 and extends to the outlet of the flue gas inlet pipe 3 inside the housing 1. Above the surface of the acidic seawater, that is, the flue gas does not enter the acidic seawater, so it is suitable for introducing flue gas vertically. It has a shell 1, the washing layer 7 with packing is fixed on its inside, and the liquid sump 15 with seawater discharge port 16 is below its inside; The outside of the casing 1 is introduced into the flue gas conduit 3 inside the casing 1. One end of the flue gas conduit 3 is the flue gas inlet 3.1 outside the casing, and the other end is the flue gas inlet 3.2 inside the casing; the flue gas inlet 3.2 in the casing extends to Inside the casing 1, it is located between the washing layer 7 and the liquid sump 15; the cooler 4 for cooling the high-temperature flue gas 2 is located in the flue gas passage between the flue gas inlet 3.1 ou...

Embodiment 2

[0099] Embodiment 2: as figure 2 Shown is another embodiment of the sea-going ship smoke exhaust scrubbing device. The difference from Example 1 is that the flue gas inlet 3.2 in the casing is on the inner wall of the casing 1, which is the outlet of the flue gas conduit 3 fixedly connected to the side wall of the casing 1, and the flue gas inlet 3 can always be kept in the liquid sump 15 above the acidic seawater liquid level, that is, the flue gas does not enter the acidic seawater, and is suitable for introducing flue gas laterally; the liquid collection pool 15 is the side of the shell below the horizontal cross section where the lower edge of the flue gas inlet 3.2 in the shell is located wall and bottom.

Embodiment 3

[0100] Embodiment 3: It is another embodiment of the smoke exhaust washing device for seagoing ships. The difference from the above embodiments is that the cooler 4 is installed on the flue gas duct 3, and may also be a cooling pipe or a cooling fin in the lumen.

Abstract

The invention relates to a sea boat smoke exhaust washing device and a washing method. The device comprises a shell, a washing layer which is arranged at the upper part in the shell, a liquid collecting pool which is arranged at the lower part in the shell, a shell internal flue gas guide-in port arranged between the washing layer and the liquid collecting pool, a washing seawater inlet which is arranged above the washing layer and the cooler of the flue gas passage which is arranged between the shell external flue gas inlet and the washing layer; the method comprises the steps such as guiding in the flue gas, cooling and injecting the washing seawater and washing, etc. The invention provides the high-effect smoke exhaust absorption washing device and method which are suitable for high smoke temperature and narrow space of the sea boat, and has the advantages of high exhaust reduction efficiency, low running energy consumption, small volume and long service life.

Description

technical field [0001] The invention relates to a sea-going ship smoke exhaust washing device and a washing method, which use seawater to wash and reduce the emission of pollutants mainly sulfur dioxide in the sea-ship ship smoke, and belong to the technical field of atmospheric environmental protection and sea-going ship smoke pollution prevention and control. Background technique [0002] Over the past 20 years, the international legislation to reduce emissions of gaseous pollutants mainly sulfur dioxide emitted by industrial facilities has been gradually tightened and improved. In recent years, the restricted objects have developed from land-based industrial facilities to sea-based ships. [0003] After the issue of reducing sulfur dioxide emissions from ships was raised globally, there was a trend of emphasizing seawater flue gas desulfurization technology. In 2007, a research report by a joint institution of four internationally renowned universities clearly stated that...
