Problems solved by technology

However, this ship exhaust gas scrubber has the following disadvantages: in sea areas where seawater washing is not allowed, that is, when the main and secondary scrubbing sections need to select the scrubbing liquid circulation system at the same time, the first scrubbing liquid nozzle of the main scrubbing section and the secondary scrubbing section The second washing liquid nozzles all draw the same alkali liquid from the same liquid storage tank, which does not play the role of cascade washing in the main and auxiliary washing sections

Abstract

The invention discloses a marine exhaust gas washing device, which comprises a washing tower body, wherein a marine exhaust gas inlet, an evaporative cooling area, a first washing area, a second washing area and a marine exhaust gas outlet; a first ventilation liquid barrier is arranged between the evaporative cooling area and the first washing area; a second ventilation liquid barrier is arrangedbetween the first washing area and the second washing area; an independent cooling liquid circulating system is arranged in the evaporative cooling area; the first washing area is connected with a first alkaline liquid circulating system; the first washing area performs primary washing on the marine exhaust gas by use of the alkaline liquid supplied by the first alkaline liquid circulating system; the second washing area is connected with a second alkaline liquid circulating system; the second washing area performs secondary washing on the marine exhaust gas by use of the alkaline liquid supplied by the second alkaline liquid circulating system; concentration of the alkaline liquid supplied by the first alkaline liquid circulating system is different from that of the alkaline liquid supplied by the second alkaline liquid circulating system. The marine exhaust gas washing device disclosed by the invention has the advantages that gradient washing can be performed on the marine exhaust gas, and the effects of sulfur removal and particle removal are good.

Description

technical field [0001] The invention relates to a ship tail gas purification device, in particular to a ship tail gas washing device. Background technique [0002] The invention patent announced by China "A Ship Exhaust Gas Scrubber and Its Application Method" (Patent No. ZL201310343654.X) discloses a ship exhaust gas scrubber and its use method. The scrubber includes a scrubber body, a scrubber The body is equipped with a ship exhaust gas inlet and a ship exhaust gas outlet. The scrubber body is equipped with a main scrubbing section and a secondary scrubbing section. The liquid washing liquid circulation system, the main washing section and the auxiliary washing section are provided with a ventilation liquid blocker to allow the gas to flow and prevent the liquid from flowing. After the exhaust gas inlet of the ship passes through the main washing section and the auxiliary washing section in turn to complete the washing of the ship exhaust gas, it is discharged from the e...
