Description

Technical Field

[0001] The utility model relates to the technical field of circulating dehumidification, in particular to a cabin circulating dehumidification device for a dual-purpose oil and chemical ship. Background Art

[0002] Oil and chemical tankers are a collective term for tankers that transport oil and chemicals. Oil tankers primarily transport heavy oil (crude oil), clean oil (diesel), refined oil, palm oil, olive oil, and other refined products, while chemical tankers primarily transport toxic, flammable, and highly corrosive liquids, such as phosphoric acid, aniline, potassium permanganate, hydrochloric acid, methanol, benzene, and sulfuric acid. The unique nature of oil and chemical tanker transport necessitates thorough cleaning after each transport to maintain a clean and tidy hold. High-pressure water jetting is currently the most widely used technology. This technology utilizes a high-pressure water pump to increase the pressure of ordinary water and eject it from a nozzle, creating an ultra-high-pressure water jet or abrasive water jet. The powerful impact, erosion, and stripping capabilities of the water jet can rapidly remove coatings, scale, rust, and oil stains.

[0003] After cleaning, the hold needs to be dried. Currently, most cargo hold drying equipment uses a combination of a purge fan and a heater, heating the air outside the hold and then passing it directly into the hold for drying. However, this method has a drawback: due to the high humidity found in ships' maritime environments, the relative humidity can reach 70%, significantly impacting cargo hold dehumidification efficiency and increasing operating costs for shipowners.

[0004] Therefore, a cabin circulation dehumidification device for a dual-purpose oil and chemical ship is proposed, and the device is upgraded and modified to solve these problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems of the background technology and provide a cabin circulation dehumidification device for a dual-purpose oil and chemical ship.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A cabin circulation dehumidification device for an oil and chemical dual-purpose ship comprises an outer shell, an inner wall of the outer shell is fixedly mounted with a drying fan, one end of the drying fan is fixedly mounted with an air outlet pipe, the inner wall of the air outlet pipe is fixedly mounted with a heating component, one end of the air outlet pipe is fixedly mounted inside the cabin, an exhaust fan is fixedly mounted on the lower side of the outer end of the outer shell, an exhaust pipe is fixedly mounted on the outer end of the exhaust fan, one end of the exhaust pipe is fixedly mounted inside the cabin, a condensation plate is fixedly mounted on the inner wall of the outer shell, a plurality of mounting plates are fixedly connected to the inner wall of the outer shell, a PP cotton filter element plate, a quartz sand filter plate and a composite water-absorbing filter paper plate are slidably connected to the inner side of the mounting plate, an exhaust port is fixedly mounted on the upper end of the outer shell, and one end of the exhaust port is connected to the air inlet of the drying fan.

[0008] Furthermore, an air intake pipe is fixedly mounted on the outer end of the shell, and a valve is fixedly mounted on the inner wall of the air intake pipe.

[0023] like Figures 1 to 3As shown, a cabin circulation dehumidification device for an oil and chemical dual-purpose ship comprises an outer shell 1, an inner wall of the outer shell 1 is fixedly mounted with a drying fan 16, one end of the drying fan 16 is fixedly mounted with an air outlet pipe 18, the inner wall of the air outlet pipe 18 is fixedly mounted with a heating component 17, one end of the air outlet pipe 18 is fixedly mounted inside the cabin, an exhaust fan 12 is fixedly mounted on the lower side of the outer end of the outer shell 1, an exhaust pipe 11 is fixedly mounted on the outer end of the exhaust fan 12, one end of the exhaust pipe 11 is fixedly mounted inside the cabin, a condensation plate 25 is fixedly mounted on the inner wall of the outer shell 1, a plurality of mounting plates 24 are fixedly connected to the inner wall of the outer shell 1, a PP cotton filter element plate 23, a quartz sand filter plate 22 and a composite water-absorbing filter paper plate 21 are slidably connected to the inner side of the mounting plate 24, an exhaust port 20 is fixedly mounted on the upper end of the outer shell 1, and one end of the exhaust port 20 is connected to the air inlet of the drying fan 16;

[0024] Specifically, the drying fan 16 is started to transport the air to the air outlet pipe 18, where it is heated by the heating component and finally transported to the inside of the cabin to accelerate the evaporation of moisture inside the cabin. At the same time, the exhaust fan 12 is started to transport the moisture in the cabin to the inside of the outer shell 1, where the moisture in the air is filtered by the condensation plate 25, the PP cotton filter plate 23, the quartz sand filter plate 22 and the composite water-absorbing filter paper board 21. Finally, the dehumidified air (with residual heat) enters the drying fan 16 again through the exhaust port 20, thereby reducing the time for the heating component to heat the air.

[0025] like Figure 1 and Figure 2 As shown, an air intake pipe 13 is fixedly mounted on the outer end of the housing 1, a valve 19 is fixedly mounted on the inner wall of the air intake pipe 13, a mounting bracket 15 is slidably connected to the inner wall of the air intake pipe 13, and a filter plate 14 is fixedly mounted on the inner wall of the mounting bracket 15; specifically, it is convenient for external (moisture-containing) air to enter the interior of the housing 1, and at the same time, impurities in the external air are filtered.

[0026] like Figure 1 and Figure 3 As shown, a water collecting tank 26 is provided at the bottom of the housing 1, and a drain pipe 10 is fixedly installed at the bottom of the water collecting tank 26; specifically, the water droplets collected by the condensation plate 25 are collected for use in other places.

[0028] In summary: when the dehumidification equipment is in use, the valve 19 is opened to allow external air (containing moisture) to enter the air inlet pipe 13, and the air is transported to the air outlet pipe 18 by starting the drying fan 16. The heating component 17 is started to heat the air in the air outlet pipe 18 and transport it to the inside of the cabin to accelerate the evaporation of moisture inside the cabin. At the same time, the exhaust fan 12 is started to transport the moisture in the cabin to the inside of the outer shell 1. The moisture in the air is filtered by the condensation plate 25, the PP cotton filter plate 23, the quartz sand filter plate 22 and the composite water-absorbing filter paper board 21. Finally, the dehumidified air (with residual heat) enters the drying fan 16 again through the exhaust port 20, reducing the time the heating component heats the air.

[0029] The valve 19 is closed or the air intake is reduced to reduce the amount of external (moisture-containing) air entering the drying fan 16, so that the air circulates inside the housing 1 and accelerates the dehumidification effect.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
