Problems solved by technology

The pressure loss of the plate heat exchanger selected for cooling ammonia water is relatively large, which will lead to high back pressure at the outlet of the hydraulic jet pump and affect the efficiency of the jet pump
At the same time, this method does not need to consider the incomplete absorption of ammonia gas in the case of this patent, so this method cannot be directly applied to the working conditions of ammonia emission treatment

Abstract

The invention provides a ship ammonia gas treatment system. The ship ammonia gas treatment system comprises an ammonia gas gathering pipe, a heat exchange unit, an ammonia gas heater, a hydraulic jet pump, an ammonia water circulating pump, an ammonia water cooler, a gas-liquid separator, an absorption tower and a ventilation mast. According to the invention, ammonia gas absorption by water is divided into three stages of jet mixing absorption, bubbling absorption and spraying absorption, so that the contact time of ammonia gas and water can be effectively ensured, the ammonia gas absorption efficiency is improved, and ammonia gas is fully absorbed. The ship ammonia gas treatment system not only can efficiently and fully absorb ammonia gas, but also has the characteristics of simple structure, safety, reliability, easiness in control, small occupied space and the like. The invention further provides a ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship ammonia gas processing system and a ship. Background technique [0002] With the increasingly serious greenhouse effect, a global upsurge of carbon emission reduction has been launched. In the shipping industry, clean energy has also developed rapidly, and will gradually replace fossil energy as the main energy source for future ships. As a chemical product that is easy to obtain and store, ammonia has no carbon in its combustion emissions. It has gradually entered the marine fuel industry and has become one of the most promising marine clean fuels. Therefore, the marine industry has gradually increased the research on ammonia fuel. strength. [0003] Ammonia is a toxic substance. Considering the safety of ships, the classification society has clearly stipulated the ammonia emission of ammonia fuel system. Discharge, after discharge, it shall not cause ammonia concentratio...
