Underwater power and structure mixing pressurization exhaust device

Abstract

The invention relates to an underwater mixing pressurization exhaust device, which comprises a carrier shell communicated with atmosphere and a power system arranged in the carrier shell, wherein the power system is provided with an exhaust pipe, the front end of the exhaust pipe is provided with an exhaust port, the position of the exhaust pipe, which is adjacent to the exhaust port, is provided with a unidirectional exhaust valve, and is further provided with an air compressor used for pressurizing exhaust gas, and the exhaust port of the air compressor is positioned between the unidirectional exhaust valve and the exhaust port. The underwater mixing pressurized exhaust device provided by the invention adopts the external air compressor, and utilizes high pressure gas produced by the air compressor to overcome the external seawater back pressure; and bubbles are formed in a breeches pipe at the tail end of the exhaust pipe, so that the exhaust gas exhausted by the power system can be smoothly exhausted to the external environment. When the operation of the underwater mixing pressurization exhaust device stops working, a valve core tightly adheres to a valve seat under the action of the seawater so as to prevent the seawater from flowing into the power system. The gas is exhausted by controlling the pressurization of the air compressor, so that the pressure in the breeches pipe keeps constant, and the invalid operating time of the air compressor is reduced.

Description

technical field [0001] The invention relates to an exhaust device of an underwater vehicle, in particular to an underwater mixed pressurized exhaust device. Background technique [0002] In terms of ship engine exhaust, large ships such as passenger ships often use chimney exhaust. This exhaust method causes a lot of oily smoke to accumulate on the rear deck of the ship, especially in windy conditions. Small yachts such as high-speed boats often use tail exhaust or side exhaust. These two exhaust methods make a large amount of exhaust gas and waste residue into the air, which greatly affects the interest of tourists. [0003] According to the data, in the same type of ship, the exhaust noise in the air can be reduced by 10~20dB by using the underwater exhaust method than by not using the underwater exhaust method. The underwater exhaust method can not only be widely used on passenger ships, yachts, customs, frontier defense, port surveillance, marine surveillance, fishery a...
