High-efficiency ship seawater desulfurization device

Abstract

The invention belongs to the field of seawater desulfurization technologies and particularly discloses a high-efficiency ship seawater desulfurization device. The device comprises a reaction tower, anexhaust pipe, a water inlet pipe, a smoke inlet and a drainage port, wherein through grooves are formed in the upper surface and the lower surface of the reaction tower respectively, the through groove at the upper side is connected with a gas collection cover through screws, the volume of the reaction tower is expanded, a larger reaction space is provided, the desulfurization reaction efficiencyof smoke and seawater is improved, and therefore smoke desulfurization can be quickly performed; through cooperation of a driving rotary shaft, a strut and a mixing impeller, the seawater and the smoke can be quickly stirred and mixed to be in full contact under the action of the rotating mixing impeller, and therefore the desulfurization effect is improved; and through an intelligent working mode of a sulfur content sensor, a main control module, a power regulator and a suction motor, the amount of entering seawater can be controlled in a feedback control mode, and therefore the functions ofguaranteeing the desulfurization effect and lowering energy consumption can be achieved.

Description

technical field [0001] The invention relates to the technical field of seawater desulfurization, in particular to a high-efficiency ship seawater desulfurization device. Background technique [0002] Seawater flue gas desulfurization is to use the natural alkalinity of seawater to absorb SO in flue gas 2 A desulfurization process. Because the rainwater brings the alkaline substances (carbonates) of the rock formations on the land into the sea, the natural seawater is usually alkaline, with a pH value generally greater than 7, and its main components are chlorides, sulfates and a part of soluble carbonates. Carbonate (HCO 3 - ), the natural alkalinity is about 1.2-2.5mmol / L, which makes seawater have natural acid-base buffering capacity and absorbs SO 2 Ability. A basic theoretical basis for seawater desulfurization is that most of the sulfur in nature exists in the ocean, sulfate is one of the main components of seawater, and most of the sulfur dioxide in the environmen...

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-efficiency seawater desulfurization device for ships to solve the problem that the existing equipment proposed in the background art above desulfurizes, usually the contact between seawater and flue gas ends, so the utilization rate of seawater is relatively low , and the desulfurization effect is relatively poor, resulting in incomplete desulfurization, which leads to the problem of substandard emissions
