Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a condenser.

Referring to fig. 1 and 2, a condenser includes a protection tank 1, a first cooling pipe 2, a steam pipe 4, and a water circulation mechanism 13. Steam pipe 4 and first cooling tube 2 all are located inside protection jar 1, and intake pipe 5 is installed on the top of protection jar 1, and outlet duct 6 is installed to the bottom of protection jar 1. Two ends of the steam pipe 4 are respectively communicated with the air inlet pipe 5 and the air outlet pipe 6, and the central axis of the steam pipe 4 along the height direction is collinear with the central axis of the protective tank 1 along the height direction. The first cooling pipe 2 is threaded around the steam pipe 4. The periphery of the protection tank 1 is fixedly provided with a water inlet pipe 7 and a water outlet pipe 8, and two ends of the first cooling pipe 2 are respectively communicated with the water inlet pipe 7 and the water outlet pipe 8. A water circulation mechanism 13 for controlling the flow of water in the first cooling pipe 2 is arranged between the water inlet pipe 7 and the water outlet pipe 8.

Referring to fig. 1 and 2, the water circulation mechanism 13 includes a water pump 131 and a water tank 132; the water tank 132 is disposed at one side of the protection tank 1. The water pump 131 is installed in the water inlet pipe 7, one end of the water inlet pipe 7, which is far away from the protection tank 1, is located inside the water tank 132, and one end of the water outlet pipe 8, which is far away from the protection tank 1, is located inside the water tank 132.

Referring to fig. 2 and 3, a plurality of shielding plates 9 are provided inside the steam pipe 4, and each shielding plate is arranged at intervals along the length direction of the steam pipe 4. A plurality of connecting rods 12 are fixedly mounted on the peripheral side of each baffle plate 9, and one ends of the connecting rods 12 far away from the baffle plates 9 are fixedly connected with the inner wall of the steam pipe 4. The space for the liquid condensed by the steam to pass through is formed between the peripheral side of the shielding plate 9 and the inner wall of the steam pipe 4.

Each of the shielding plates 9 is curved toward the upstream direction in which steam is sent from the steam pipe 4, which is advantageous in guiding the liquid adhering to the surface of the shielding plate 9 to flow toward the peripheral side of the shielding plate 9, thereby leaving the liquid from the space between the shielding plate 9 and the inner wall of the steam pipe 4.

The shielding plates 9 are provided with a plurality of through holes 10 for steam to pass through, and the projections of the through holes 10 of two adjacent shielding plates 9 along the length direction of the steam pipe 4 are not overlapped. This facilitates the steam discharged from the through-holes 10 of the upstream shielding plate 9 to collide with the downstream shielding plate 9, thereby slowing the flow rate of the steam and increasing the time for which the steam remains inside the steam pipe 4.

Referring to fig. 2 and 4, a blower 15 and a nozzle 16 are fixedly mounted at the top end of the protection can 1, and both the blower 15 and the nozzle 16 face the steam pipe 4. A conduit 14 is connected to the spray head 16, and an end of the conduit 14 remote from the spray head 16 is communicated with the first cooling pipe 2. The water in the first cooling pipe 2 flows along the guide pipe 14 toward the shower head 16 and is sprayed toward the steam pipe 4 and the first cooling pipe 2 spirally wound around the steam pipe 4. Then, the blower 15 accelerates the rate of heat absorption by evaporation of the water sprayed from the spray head 16, thereby accelerating the rate of liquefaction of the steam inside the steam pipe 4. This is advantageous in increasing the condensing speed of the condenser.

A liquid discharge pipe 17 is installed at the bottom end of the protection tank 1, the liquid discharge pipe 17 is communicated with the inside of the protection tank 1, and one end of the liquid discharge pipe 17, which is far away from the protection tank 1, is positioned inside the water tank 132. This facilitates the removal of non-evaporated water from the water sprayed by the spray head 16. While the lowest point of the protection tank 1 is higher than the highest point of the water tank 132, so that the water inside the protection tank 1 automatically flows to the water tank 132 under the influence of gravity.

An exhaust pipe 18 is fixedly arranged on the outer wall of the protection tank 1, and the exhaust pipe 18 is communicated with the interior of the protection tank 1. The water sprayed from the spray head in the protective tank 1 is evaporated and then discharged from the exhaust pipe 18.

The implementation principle of a condenser of the embodiment of the application is as follows: steam enters the steam pipe 4 from the air inlet pipe 5, the shielding plate 9 blocks the steam from flowing to the air outlet pipe 6, and the condensation time of the steam is prolonged, so that the steam is discharged from the air outlet pipe 6 after being fully condensed.

The water pump 131 pumps water from the water tank 132 and then feeds the water from the water inlet pipe 7 into the first cooling pipe 2, and then the water in the first cooling pipe 2 is discharged from the water outlet pipe 8 and re-enters the water tank 132. Meanwhile, the water in the first cooling pipe 2 enters the second cooling pipe 3 through the connecting pipe 11 to absorb heat and then is discharged into the first cooling pipe 2 through the connecting pipe 11 again. In this way, the water pump 131 pumps water from the water tank 132, and the water re-enters the water tank 132 after absorbing heat emitted when the steam is condensed after flowing through the first cooling pipe 2 and the second cooling pipe 3. The heat emitted by the steam is absorbed by the water, so that the condensation speed of the steam is increased.

The water in the first cooling pipe 2 is also sprayed from the spray head 16 to the steam pipe 4, and the blower 15 blows air to the steam pipe 4 to accelerate the air flow speed in the steam tank, thereby accelerating the evaporation speed of the water sprayed from the spray head 16. The water sprayed from the spray head 16 absorbs the heat emitted from the steam, thereby accelerating the condensation rate of the steam.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
