Description
技术领域technical field
本实用新型涉及船舶技术领域，特别涉及一种排气管泄放装置。The utility model relates to the technical field of ships, in particular to an exhaust pipe discharge device.
背景技术Background technique
船用柴油机、焚烧炉、锅炉等需要燃烧柴油的大型设备均需连接排管至烟囱，通过烟囱将废气排放到大气中。排气管通常连接有泄放管，用于排放排气管中的烟灰、污水等杂物。现有的设计方案中，泄放管为一条安装有截止阀和存水弯的管路，该泄放管在使用的过程中会逐渐积累污水、烟灰等物，如果不及时处理，会引起泄放管堵塞，进而导致污水流入增压器而损坏增压器，造成安全隐患。此外，由于泄放管直通舱底，泄放管堵塞后，内部的油气回流至内舱，会污染机舱环境。Marine diesel engines, incinerators, boilers and other large-scale equipment that need to burn diesel oil need to be connected to the chimney, and the exhaust gas is discharged into the atmosphere through the chimney. The exhaust pipe is usually connected with a discharge pipe for discharging soot, sewage and other sundries in the exhaust pipe. In the existing design scheme, the discharge pipe is a pipeline equipped with a stop valve and a water trap. The discharge pipe will gradually accumulate sewage, soot and other substances during use. If it is not treated in time, it will cause leakage. The discharge pipe is blocked, which will cause sewage to flow into the supercharger and damage the supercharger, causing a safety hazard. In addition, since the discharge pipe is directly connected to the bottom of the bilge, when the discharge pipe is blocked, the internal oil and gas will flow back to the inner cabin, which will pollute the engine room environment.
