Efficient nozzle for ship desulfurization system

Abstract

The invention belongs to the technical field of ship desulfurization, and in particular, relates to an efficient nozzle for a ship desulfurization system. The efficient nozzle comprises a liquid accumulation barrel; the left side wall of the liquid accumulation barrel is connected with a liquid inlet through a flange; the side wall of the liquid inlet is connected with an air inlet pipe through aflange; a rotating shaft is longitudinally arranged in an inner cavity of the liquid accumulation barrel; the upper end of the rotating shaft is in shaft connection with a supporting bearing, the supporting bearing is arranged at the upper end of the inner cavity of the liquid accumulation barrel through a shaft seat, and the outer wall of the rotating shaft is sleeved with a driving impeller. Through the effect of uniformly dispersing seawater, the amount of entering seawater is small, the atomization effect is good, large-area contact with flue gas can be achieved, and thus the desulfurization effect can be improved; through cooperation of the driving impeller, the rotating shaft, the supporting bearing and the like, the connecting base and the liquid accumulation barrel can relatively rotate, so that the connecting base can drive a liquid outlet pipe and a liquid outlet spray head to rotate, the spraying position can be enlarged, and the spraying uniformity is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship desulfurization, in particular to a high-efficiency nozzle for a ship desulfurization system. Background technique [0002] In the world's cargo transportation, ocean transportation occupies a large proportion. Ocean cargo transportation has the characteristics of large traffic capacity, large transportation volume, low freight, strong adaptability to goods, low speed, and high risk. At present, more than two-thirds of the total volume of international trade, and 90% of my country's total import and export goods are transported by sea. [0003] With the rapid increase in the number of transport ships, the pollution and harm caused by the pollutants discharged by ships to the atmospheric environment and marine environment are also becoming more and more serious. The tail gas emitted by marine diesel engine combustion is mainly sulfur dioxide SO2 and nitrogen oxide NO2. According to the statistics of...

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-efficiency nozzle for a ship desulfurization system to solve the problem that the existing seawater desulfurization equipment proposed in the above background technology is prone to seawater and smoke when the seawater entering is less. The contact of gas is not uniform enough to reduce the desulfurization effect. Whenever there is too much seawater entering the house, the amount of flue gas output will be affected, thereby reducing the efficiency.
