Description
Technical Field
The invention relates to the technical field of marine diesel engine tail gas treatment, in particular to a marine exhaust gas washing and desulfurizing device.
Background
The marine transportation industry is the economic development of the modern societyIn the important field, the tonnage and the quantity of ships both sharply rise along with the increase of world trade volume. Marine diesel engines are a key power source in transportation in modern world trade. In order to reduce the transportation cost of ships, low-quality fuel oil with high sulfur content is generally used as fuel, and the tail gas of an engine contains a large amount of SO2Nitrogen oxides and particulate matter, ship to SO2There are clear restriction criteria to be ruled out. The use of low-sulfur fuel and the additional installation of a waste gas desulfurization device are main technical measures for realizing that the sulfur emission of the ship tail gas meets the emission standard. Many studies have shown that wet scrubbing desulfurization is a more economical way to facilitate stable operation of marine diesel engines for both operational and newly constructed ships. A plurality of scientific research institutions at home and abroad are dedicated to relevant research on the ship waste gas washing and desulfurizing system.
At present, wet scrubbing desulfurization is the main technical measure for meeting the requirements of the sulfur content of fuel oil by regulations on ships, and comprises an open desulfurization mode, a closed desulfurization mode and a mixed desulfurization mode. The open desulfurization system utilizes the alkalinity of natural seawater to neutralize SO in waste gas2The system has simple composition and low control logic complexity. However, the natural alkalinity of the seawater is low, so that the quality of the discharged washing wastewater is not easy to reach the standard and cannot be used in certain specific areas. The closed desulfurization system is characterized in that alkaline substances are additionally added into the washing liquid to neutralize and absorb SO2The material of the system is more, the closed system equipment is more, the control logic is complex, and the washing wastewater quality is easy to control. At present, the existing exhaust gas scrubbing desulfurization technology has some defects in practical application.
In a patent 'marine desulfurization system' with the application number of 201520779599.3, a desulfurization tower part of the invention is only composed of a spraying layer, waste gas in a chimney enters from the bottom of the desulfurization tower to directly contact and react with spraying washing liquid up and down, the gas-liquid contact area is not large, the desulfurization reaction is insufficient, and in order to ensure the desulfurization effect, multiple layers of spraying are needed, so that the height of the tower is increased; and the invention does not consider the side wall effect of the tower wall of the desulfurizing tower, and partial waste gas is discharged outside the tower without desulfurization reaction, which is not beneficial to practical application.
In patent 201822166899.0 entitled "desulfurizing tower capable of circularly flushing demister", the flue gas inlet of the device of the invention is at the bottom of the desulfurizing tower, the waste gas moves from bottom to top, and there is a phenomenon that part of the waste gas moves upwards along the inner side of the tower wall, which easily causes the part of the waste gas to be directly discharged without reacting with the washing liquid, thus reducing the desulfurizing efficiency; the desulfurization device has a single structure, the gas-liquid contact area is small, and the desulfurization reaction efficiency and speed are reduced; the washing liquid in the invention adopts a circulating structure, and the concentration of the washing liquid is lower and lower in the actual working condition, so that the reaction speed is slowed down.
In the patent 'an apparatus and method for wet desulfurization of high temperature flue gas' with application number 201910715749.7, the circulating liquid of the desulfurization tower is cooled by condensed water. In the desulfurization reaction stage, the waste gas is simply introduced into the washing liquid, the reaction is insufficient, and the desulfurization effect is poor; in the process that the waste gas enters the reaction solution and is discharged out of the tower, the waste gas does not pass through a demisting device, so that washing liquid drops are easy to carry out, and the waste gas can carry unreacted sulfur oxide due to insufficient reaction, so that the external device is polluted and seriously corroded; the side wall effect is not considered in the spraying and cooling process, and part of gas is discharged out of the tower without being cooled, so that the temperature of the gas discharged out of the desulfurizing tower is higher.
In summary, the existing ship desulfurization system has some defects in practical application, so it is necessary to develop a set of ship exhaust gas washing desulfurization system with high efficiency, low cost, convenient installation and good safety.
