Description

Technical Field

[0001] This utility model relates to the field of marine drying, specifically a new type of marine air dryer. Background Technology

[0002] During navigation, the high humidity and salt content of the air inside the ship's cabin can easily lead to equipment corrosion, pipeline blockage, and system failure.

[0003] Adsorption dryers require compressed air for regeneration, resulting in high energy consumption. The adsorbent needs to be replaced or regenerated regularly, and the internal cleaning of the equipment is difficult. Cooling and dehumidification technology is limited by the condensation area and airflow distribution, leading to insufficient water vapor condensation and unstable dehumidification effect. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a novel marine air dryer.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A novel marine air dryer includes a condenser box. The left end of the condenser box is fixedly connected to an air outlet pipe, and the right end is fixedly connected to a ventilation pipe. An induced draft fan is installed inside the air outlet pipe. The right end of the ventilation pipe is threadedly connected to an air inlet pipe. Heating wire is wound around the outer wall of the air inlet pipe, which has an outer cylinder. The air inlet pipe is inside the outer cylinder, which has constricted ends. The left and right ends of the outer cylinder are fixedly connected to the outer walls of the two ends of the air inlet pipe. Brackets are located on the left and right sides of the bottom of the outer cylinder, and these brackets are fitted onto the outer wall of the outer cylinder. Both the inner walls of the condenser box and the outer cylinder are insulated. The condenser box contains three condensing plates. The condenser plates are equidistantly distributed horizontally and vertically, with their outer walls fixedly connected to the inner walls of the condenser box. Water flow channels are opened inside the condenser plates, forming a serpentine tube shape. Water pipes are fixedly connected between the inlet and outlet ends of the water flow channels in adjacent condenser plates. The inlet end of the water flow channel of the right condenser plate is fixedly connected to the cold water inlet pipe, and the outlet end of the water flow channel of the left condenser plate is fixedly connected to the cold water outlet pipe. The cold water inlet and outlet pipes pass through the rear and front side walls of the condenser box, respectively. Three drain pipes are fixedly connected to the bottom of the condenser box, and the drain pipes are staggered with the left and right condenser plates. Valves are installed on the drain pipes.

[0007] The bottom ends of the left and right condenser plates are fixedly connected to the inner bottom wall of the condenser box, and there is a gap between the top ends of the left and right condenser plates and the inner top wall of the condenser box. The upper end of the middle condenser plate is fixedly connected to the upper inner wall of the condenser box, and there is a gap between the bottom end of the middle condenser plate and the inner bottom wall of the condenser box.

[0008] A groove is provided on the bottom inner wall of the condenser box between the left condenser plate and the left inner wall of the condenser box; a groove is provided on the bottom inner wall of the condenser box between the left and right condenser plates; and a groove is provided on the bottom inner wall of the condenser box between the right condenser plate and the right inner wall of the condenser box. The bottom of the three grooves are respectively connected to three drain pipes.

[0009] The beneficial effects of this utility model are:

[0010] This invention utilizes three staggered condenser plates, combined with a serpentine water flow channel, to significantly extend the contact time between air and the condenser plates, thereby improving the efficiency of water vapor condensation. This allows the humid air to be dried and discharged, while the insulation layer between the condenser box and the inner wall of the outer cylinder reduces energy loss. Attached Figure Description

[0019] like Figure 1-7As shown: A novel marine air dryer includes a condenser box 1, with an outlet pipe 2 fixedly connected to the left end of the condenser box 1 and a ventilation pipe 4 fixedly connected to the right end of the condenser box 1. An induced draft fan 3 is installed inside the outlet pipe 2. An inlet pipe 13 is threaded to the right end of the ventilation pipe 4. Heating wire 14 is wound around the outer wall of the inlet pipe 13. An outer cylinder 15 is formed on the outer wall of the inlet pipe 13, and the inlet pipe 13 is located inside the outer cylinder 15. The left and right ends of the outer cylinder 15 are constricted and fixedly connected to the outer walls of both ends of the inlet pipe 13. Brackets 16 are provided on both the left and right sides of the bottom of the outer cylinder 15, and the brackets 16 are fitted onto the outer wall of the outer cylinder 15. Insulation layers 5 are provided on the inner walls of both the condenser box 1 and the outer cylinder 15. The condenser box 1 contains three condensation plates. 6. Three condenser plates 6 are equidistantly distributed horizontally and vertically, with their outer walls fixedly connected to the inner wall of the condenser box 1. Water flow channels 7 are opened inside the condenser plates 6, and the water flow channels 7 are in the shape of serpentine tubes. Water pipes 8 are fixedly connected between the inlet and outlet ends of the water flow channels 7 in adjacent condenser plates 6. The inlet end of the water flow channel 7 of the right condenser plate 6 is fixedly connected to the cold water inlet pipe 9, and the outlet end of the water flow channel 7 of the left condenser plate 6 is fixedly connected to the cold water outlet pipe 10. The cold water inlet pipe 9 and the cold water outlet pipe 10 pass through the rear and front side walls of the condenser box 1, respectively. Three drain pipes 11 are fixedly connected to the bottom of the condenser box 1. The drain pipes 11 are staggered with the left and right condenser plates 6, and valves 12 are installed on the drain pipes 11.

[0020] The bottom ends of the two left and right condensing plates 6 are fixedly connected to the inner bottom wall of the condensing box 1. There is a gap between the top ends of the two left and right condensing plates 6 and the inner top wall of the condensing box 1. The upper end of the middle condensing plate 6 is fixedly connected to the upper inner wall of the condensing box 1. There is a gap between the bottom end of the middle condensing plate 6 and the inner bottom wall of the condensing box 1.

[0021] A groove 17 is provided on the bottom inner wall of the condenser box 1 between the left condenser plate 6 and the left inner wall of the condenser box 1. A groove 17 is provided on the bottom of the inner wall of the condenser box 1 between the left and right condenser plates 6. A groove 17 is provided on the bottom inner wall of the condenser box 1 between the right condenser plate 6 and the right inner wall of the condenser box 1. The bottom of the three grooves 17 are respectively connected to three drain pipes 11.

[0022] Humid air inside the ship is drawn into the equipment through the air inlet pipe 13 by the induced draft fan 3. The heating wire 14 wrapped around the outer wall of the air inlet pipe 13 heats the humid air. The outer cylinder 15 and the bracket 16 provide support and protection for the air inlet pipe 13.

[0023] After being heated, humid air enters the condenser chamber 1, it comes into contact with three staggered condenser plates 6. Low-temperature cooling water is continuously supplied through the water flow channels 7 inside the condenser plates 6 via the cold water inlet pipe 9. The low-temperature cooling water exits through the cold water outlet pipe 10 after passing through the water flow channels 7. When the cold water in the water flow channels 7 encounters the hot, humid air, it condenses the moisture into water, forming a serpentine circulation path. This prolongs the cooling time and enhances heat exchange efficiency. The humid air cools on the surface of the condenser plates 6, causing the water vapor to condense into liquid water. The cold water inlet pipe 9 and the cold water outlet pipe 10 can be connected to an external cooling water circulation system, which is a prior art device.

[0024] Condensate flows along the surface of the condenser plate 6 into the bottom of the condenser box 1 and is periodically discharged through three drain pipes 11. The valve 12 can control the timing of drainage. The insulation layer 5 of the condenser box 1 reduces energy loss and maintains a low-temperature environment.

[0025] The dry air after multi-stage condensation and dehumidification is discharged through the air outlet pipe 2. The exhaust fan 3 provides continuous power, and the staggered layout of the condenser plates 6 guides the air to form an "S" shaped flow path, maximizing the contact area and dehumidification efficiency.

[0026] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
