Technical Field

The utility model relates to an air exchange system technical field especially relates to a boats and ships air exchange system and applied this system's boats and ships.

Background

The spread of certain viruses can bring great threat to the health of human bodies, each independent ship is a mobile life and work factory due to the particularity of the ship, and the living and working space of crews or passengers is relatively more closed and narrow; some viruses are mainly transmitted through aerosol in the air, and even infected or suspected personnel are isolated into independent cabins, the conventional ship is difficult to avoid the transmission of the viruses through the air, and the reasons are that firstly, the number of the cabins of an independent air conditioner is small, and the viruses are quickly diffused, so that the inhabitation of all infected personnel cannot be met; secondly, most cabin ventilation systems are commonly shared air conditioners, and after air conditioning returns, the air in all the cabins is sent back to the air conditioning box for the second time to be merged, and then the air is diffused to the whole ship.

SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides a boats and ships air exchange system and applied this system's boats and ships, it has solved the problem that air exchange system who exists can not the diffusion of the virus in the effective control isolation cabin among the prior art.

According to the utility model discloses an embodiment, a boats and ships air exchange system, include the air-conditioning box through blast pipe and return air pipe and each cabin connection, the cabin includes ordinary cabin and isolation cabin, and the blast pipe of isolation cabin just is provided with the non return air brake for independent pipeline, is provided with the air brake on the return air pipe of isolation cabin, and isolation cabin still is connected with the blast pipe, and the blast pipe independently sets up and has arranged the air discharge fan, and the end of giving vent to anger of blast pipe arranges in the spacious region of opening of boats and ships.

Preferably, an air pressure sensor for controlling the blast pipe and the exhaust fan according to the reading is arranged in the isolation chamber, and the isolation chamber maintains negative pressure.

Preferably, a filter is mounted on the exhaust pipe.

Preferably, the filter comprises a primary filter, a medium filter and a high efficiency filter which are distributed along the exhaust pipe in sequence.

Preferably, an exhaust pipe and an exhaust fan for maintaining negative pressure in the toilet are installed in the toilet of the isolation cabin, and an air outlet end of the exhaust pipe is arranged in an open area of the ship.

A ship using a ship ventilation system is provided, wherein the ship is any one of an offshore drilling platform, an offshore life/service platform, an engineering ship or a cruise ship.

Compared with the prior art, the utility model discloses following beneficial effect has:

through supplying air to ordinary cabin and isolation cabin respectively, cut off the return air pipe of isolation cabin through the air brake, exhaust the isolation cabin through the air discharge fan, through the air in blast pipe transportation isolation cabin to control with the transportation is discharged from spacious open area of boats and ships, has realized the effective isolation of virus.

The construction of the ventilation pipeline of the isolation cabin is improved on the original ventilation pipeline, so that the modification cost is reduced; in the case of non-isolation, the flow path of the gas in the isolation chamber is the same as that of the gas in the ordinary chamber, so that the gas can be returned, and the maintenance cost of the ventilation system is reduced.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the above drawings: 1. an air conditioning cabinet; 2. a common compartment; 3. an isolation cabin; 4. a non-return air brake; 5. an air supply pipe; 6. a return air duct; 7. an exhaust fan; 8. a filter; 9. and (4) exhausting the gas.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, to achieve effective isolation of the vessel from sources of disease within the vessel. The utility model provides a boats and ships air exchange system, include the air-conditioning box 1 through blast pipe 5 and return air duct 6 and each cabin connection, the cabin includes ordinary cabin 2 and isolation compartment 3, and isolation compartment 3's blast pipe 5 just is provided with non return air brake 4 for independent pipeline, is provided with the air brake on isolation compartment 3's return air duct 6, and isolation compartment 3 still is connected with blast pipe 9, and blast pipe 9 independently sets up and has arranged air discharge fan 7, and the end of giving vent to anger of blast pipe 9 arranges in the spacious open area of boats and ships.

Firstly, sealing an isolation cabin 3, canceling a bottom return air grid between a room door of the isolation cabin 3 and a passageway, and adding a sealing strip to the room door of the isolation cabin 3; the blast pipe 5 of the isolation cabin 3 is an independent pipeline, and the air in the blast pipe 5 can only flow in a single direction through the air check damper 4 (also called as an air check valve), so that the polluted air is prevented from returning to the air conditioning box 1 and then being repeatedly sent into the common cabin 2, and the safety of the ship ventilation system is improved. After the isolation cabin 3 is opened, an air brake in the air return pipe 6 of the isolation cabin 3 is automatically closed, the air return pipe 6 of the isolation cabin 3 is cut off, the exhaust fan 7 is opened, and air in the isolation cabin 3 is pumped out to the open place of the ship through the exhaust fan 7.

As a preferred embodiment of the present invention, in order to increase the isolation performance of the isolation chamber 3, the air diffusion of the interior pollution is avoided. An air pressure sensor for controlling the blast pipe 5 and the exhaust fan 7 according to the reading is arranged in the isolation chamber 3, and the isolation chamber 3 maintains negative pressure. According to the reading of the air pressure sensor, the power of the exhaust fan 7 is controlled, the air pressure in the isolation cabin 3 is ensured to be lower than the external air pressure, and the air in the isolation cabin 3 cannot diffuse outwards.

As shown in fig. 1, to further improve the safety of the gas discharged from the exhaust pipe 9. A filter 8 is mounted on the exhaust pipe 9. Since the virus is transmitted through the aerosol in the air, the contaminated gas is filtered by the filter 8, the content of the virus in the gas discharged from the gas discharge pipe 9 is reduced, and secondary contamination is prevented.

In a preferred embodiment of the present invention, the pressure of the filter 8 is reduced. The filter 8 comprises a primary filter, a secondary filter and a high-efficiency filter which are sequentially distributed along the exhaust pipe 9 outwards. By arranging the multistage filter, the contaminated gas in the exhaust pipe 9 is filtered a plurality of times, so that not only can the filtering effect be improved, but also the load of the filter can be reduced.

As a preferred embodiment of the present invention, the exhaust passage of the toilet is usually arranged independently, but the direction or exhaust outlet position is close, and there is a risk of virus spreading. An exhaust pipe 9 and an exhaust fan 7 for keeping negative pressure of the toilet are installed in the toilet of the isolation cabin 3, and an air outlet end of the exhaust pipe 9 is arranged in an open and open area of the ship. The exhaust pipe 9 of the toilet of the isolation cabin 3 is extended to the open area of the ship, so that polluted gas in the toilet is exhausted to a safe position to avoid diffusion; of course, the filter 8 is also mounted on the exhaust pipe 9.

A ship applying a ship ventilation system is any one of an offshore drilling platform, an offshore life/service platform, an engineering ship or a cruise ship. The ventilation system can be arranged in the living space of the common ventilation system, and the diffusion of viruses is avoided under the conditions of reducing the cost and meeting the living condition.
