How does a submarine exhaust when diving into deep water, and what is the purpose of the submarine e

After conventional submarines are generally submerged, the diesel engine generally stops working and uses the propulsion motor to work, and the electric energy uses the electric energy of the battery. When the submarine surfaced, the diesel engine worked, and in addition to pushing the submarine forward, it also drove the generator to charge the battery.

There are cases in which the diesel engine will also work underwater, which can be roughly divided into two situations:

1. When the diving depth is not large, that is, the periscope can reach the depth of the water surface, a pipe extends from the shell of the conning tower to the water surface, and exhaust the exhaust gas;

2 When the diving depth is very large, and the battery is not yet charged, the diesel engine will be started to work in an emergency. However, at this time, the exhaust gas will be collected into a booster and discharged after pressurization, otherwise the seawater will be poured back from the exhaust pipe due to the water pressure.

Diving deep water generally the engine does not work, so it does not exhaust (some engines are sporty, such as the Stirling engine, but it does not exclude exhaust gases). However, it is not that it does not exhaust, such as the exhaust gas used in its daily life must be eliminated.

There are two possibilities for its exclusion:

when shallower, it is excluded by a snorkel; When it is deeper, it passes through the supercharger and discharges after the pressurization.

The above refers to the Soul of the Chinese Nation - Lecture Hall Military Q Group Group Discussion.

Both the nuclear power plant and the AIP power unit can be non-exhausting, and conventional diesel-electric submarines are powered by electric motors and batteries when diving into the deep sea, and the internal combustion engine does not work.

with electric motors. Diesel engines are used on the surface of the water to generate electricity, to charge the batteries, and to drive the motors with the batteries underwater.

Nuclear power does not have this problem.

It is powered by electricity when diving, there is no exhaust problem, and it will be a catastrophic accident if you drive a diesel engine!

Diving into deep water engines does not work.

Summary. Submarine, also known as submarine, submarine, submarine, submarine. It is a ship capable of operating underwater.

There are many types of submarines, with different shapes, ranging from small civilian submersible probes that are fully automatic or operated by one or two people and have a long operation time and several hours of operation, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and dive continuously for 3-6 months. According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices. Large submarines are mostly cylindrical, and a vertical structure (bridge) is usually set up in the middle of the ship, which was called a "conning tower" in the early days, and contained communications, sensors, periscopes, and control equipment.

Today's deep-sea submarines or specialized submarines are often no longer designed to do so.

Hello, I'm glad to answer for you Here you can exhaust the exhaust gases inside the submarine, submarine, also known as submarine, submarine, submarine. It is a ship that can be transported underwater. There are many types of submarines with different shapes, ranging from a small civilian submersible probe that is fully automatic or operated by one or two people and has an operation time of several hours, to a Russian Taiwanese hood that can carry hundreds of people and continuously dive for 3-6 months.

Today's deep-sea submarines or specialized submersible chainback boats are often no longer designed in this way. Sail hunger.

Underwater air tank navigation: At a depth of 8-15 meters, the submarine underwater navigation suction device - air cylinder is raised in the submarine bridge to provide the air required for diesel engine combustion. Exhaust by the submarine underwater exhaust device at the rear end of the bridge. Both units are unidirectional and prevent seawater from backing up.

A submarine or submarine, or submarine, is a ship capable of operating underwater. There are many types of submarines, ranging from small civilian submersible probes that are fully automatic or operated by one or two people and have an operation time of several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and continue to dive for 3-6 months. According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices. [

1. The submarine is equipped with oxygen generating devices, including electrolysis of water to produce oxygen, oxygen cylinders, and liquid oxygen tanks.

2. A kind of "oxygen candle" is often used in submarines, which is made of special chemical materials and similar in shape to candles, and will produce a large amount of oxygen after being lit.

3. The boat is also equipped with carbon dioxide absorption device and air purification device, although they do not produce oxygen, they can deal with impurities and harmful gases in the air in the boat and keep the air fresh.

4. The submarine is equipped with a snorkel, and under appropriate conditions, the submarine can rise to a few meters to more than ten meters above the water surface, lift the snorkel out of the water, inhale fresh air, and exhaust the turbid air in the boat.

5. Conventional power submarines will float to the periscope depth every 24 hours to recharge, and then the whole boat can be ventilated through the diesel engine intake and exhaust system.

6. When the carbon dioxide concentration in the individual cabin reaches a certain standard, you can ask the boat command to use the regeneration medicine board to react with the carbon dioxide in the air to generate oxygen and water.

I served in the submarine force, and my first lesson as a submariner was to learn how to regulate the pressure difference between the inside and outside of the body.

Generally speaking, conventionally powered submarines will float to the periscope depth every 24 hours to recharge, and then the whole boat can be ventilated through the diesel engine intake and exhaust system.

When there is no floating, the air in each cabin of the whole boat can be stirred through the whole boat ventilation system to avoid excessive air pressure in individual cabins.

When the carbon dioxide concentration in the individual cabins reaches a certain standard (there are instruments that can be measured), you can ask the boat command to use the regenerative medicine board, the main ingredient of the regeneration medicine board is potassium peroxide, which can react with the carbon dioxide in the air to produce oxygen and water.

In addition, when sailing in deep water, in order to conceal it, it is absolutely not allowed to discharge gas, sewage, and garbage outside the boat. Everything that could be exposed.

You can also drain it when the water pressure is high, and you want to drain it when you dive on the top of the dive, isn't it more difficult than exhausting, these are not problems, it's just a little more powerful.

The chemical reaction balances the air pressure.
