Integrated dedusting, desulfurization and denitrification device for ship exhaust gases

Abstract

The invention belongs to the technical field of ship exhaust gases and particularly relates to an integrated dedusting, desulfurization and denitrification device for the ship exhaust gases. The integrated dedusting, desulfurization and denitrification device comprises a ship hull smoke exhausting tube, wherein the ship hull smoke exhausting tube is arranged vertically upwards, a plurality of supporting columns are fixedly connected to the top face of the ship hull smoke exhausting tube vertically, upper ends of the supporting columns are fixedly connected with the same supporting block, the supporting block is cylindrical, sliding grooves are coaxially formed in the upper end of the supporting block, a plurality of sliding blocks matched with the sliding grooves are arranged in the sliding grooves, a spraying mechanism is arranged in the ship hull smoke exhausting tube, the upper end of the spraying mechanism penetrates through the supporting block and is fixedly connected with a rotating mechanism, and one end, far away from the ship hull smoke exhausting tube, of the spraying mechanism is connected with a pumping feed system inside a ship hull. The integrated dedusting, desulfurization and denitrification device has the advantages that a mixed treatment solution and the exhaust gases can be subjected to reaction treatment uniformly, so as to achieve the effect of purifying the exhaust gases; and meanwhile, rotary driving can be carried out by using wind energy of navigation and kinetic energy of exhaust gas discharging, additional power of a ship is not required to be consumed, and energy power is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of ship tail gas, and in particular relates to an integrated dust removal, desulfurization and denitrification device for ship tail gas. Background technique [0002] A ship is a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats. They are collectively called ships or boats. Modern ships are generally Petroleum energy is used as power. When using fossil energy, the ship discharges the exhaust gas through the flue, but the exhaust gas also contains a certain amount of sulfide and nitrate, which are serious to the health of the atmospheric environment. threat.

Problems solved by technology

[0003] Traditional ship exhaust emissions are usually directly discharged without effective treatment. With the development of technology, exhaust gas has begun to be treated. In modern methods, ammonia water is usually used as a reducing agent to chemically react with desulfurization and denitrification catalysts to desulfurize and denitrify exhaust gas. Treatment, this method is generally more cumbersome, and it also needs to consume a lot of power to continuously mix it with the exhaust gas, and the mixing rate is relatively general, which is inconvenient to process a large amount of ship exhaust gas, and is also not conducive to subsequent emissions.
