Technical Field

[0002] A water-cooled condenser is a device that uses water as a cooling medium to condense a high-temperature and high-pressure gaseous refrigerant. In the chemical industry, due to the low boiling point of hydrocarbons and other chemicals, this type of condenser is often used as a refrigeration system when producing such chemicals. In the distillation tower, the steam will pass through the first-stage condenser, where the high-temperature steam condenses and becomes liquid. Then, the liquid will flow from the first-stage condenser to the second-stage condenser, where it will be further condensed and collected at a lower temperature.

[0003] Existing water-cooled condensers generally use water circulation for cooling. It circulates cooling water to make it contact the heat source and absorb heat, then takes the heat away and releases it to the surrounding environment. However, the cooling water cools the heat source for a long time, which may cause the temperature of the cooling water to rise, which leads to a decrease in the cooling effect. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the cooling water is used for a long time for circulating cooling, the temperature of the cooling water may increase, resulting in a decrease in the cooling effect. In order to reduce the temperature of the cooling water in the condenser, the first water pump can be turned on.

[0015] 2. In the utility model, when the material in the feeding pipe is condensed and cooled, the gas or liquid flowing in the feeding pipe will generate certain vibrations, which may cause the connection between the feeding pipe and the previous condensation mechanism to loosen or even leak. At this time, the rotating plate can be rotated, and the rotating plate drives the bidirectional screw to rotate. During the rotation process, the bidirectional screw drives the two arc-shaped clamping plates to approach each other until the connection of the feeding pipe is clamped and fixed, thereby reducing the vibration of the feeding pipe during condensation and reducing the possibility of leakage at the connection of the feeding pipe.

The circulating water pump 109 draws the cooling water in the cooling water tank 105 into the condenser 103 through the water inlet pipe 110. The cooling water in the condenser 103 then flows into the cooling water tank 105 through the water outlet pipe 108. The circulating flow of cooling water can enable the condenser 103 to cool down the material in the feeding pipe 104.

[0028] Embodiment 2, as Figure 1-Figure 6As shown, a collection frame 106 is fixedly installed on the top of the cooling water tank 105, a water injection hole 107 is opened through the top of the cooling water tank 105, a frame 120 is fixedly installed on the top of the bottom plate 101, a water spray pipe 112 is fixedly installed on the inner wall of the frame 120, a group of atomizing nozzles 113 are arranged on the outer wall of the water spray pipe 112, a first water pump 111 is fixedly installed on the top of the bottom plate 101, and the output end of the first water pump 111 is fixedly connected to the water spray pipe 112.

The clamping mechanism 2 comprises a second housing 201, and a bidirectional screw 202 is movably inserted into the inner wall of the second housing 201, and two sliders 203 are threadedly connected to the outer wall of the bidirectional screw 202, and the two sliders 203 are movably inserted into the inner wall of the second housing 201. An arc-shaped clamping plate 204 is fixedly mounted on the outer wall of the two sliders 203, and rubber pads are fixedly mounted on the inner wall of the two arc-shaped clamping plates 204, and a rotating plate 205 is movably inserted into the outer wall of the second housing 201, and the output shaft of the rotating plate 205 penetrates the inner wall of the second housing 201 and is fixedly connected to one end of the outer wall of the bidirectional screw 202.

[0029] The effect achieved by the entire embodiment 2 is that when the cooling water is used for a long time for circulation cooling, the temperature of the cooling water may increase, resulting in a reduction in the cooling effect. In order to reduce the temperature of the cooling water in the condenser 103, the first water pump 111 can be turned on. The first water pump 111 draws water from the cooling water tank 105 into the water spray pipe 112, and then sprays the cooling water on the surface of the condenser 103 through a group of atomizing nozzles 113. The cooling water absorbs the heat on the surface of the condenser 103 and evaporates, thereby reducing the temperature of the pipeline, thereby reducing the temperature of the cooling water inside the condenser 103. At the same time, the two heat dissipation fans 119 can be turned on. The wind generated by the heat dissipation fans 119 can accelerate the evaporation of water on the surface of the condenser 103 and take away the heat, thereby further reducing the temperature of the condenser 103, thereby reducing the temperature of the condenser. The temperature of the cooling water inside 103 further drops, and then the motor 115 is turned on. The motor 115 drives the threaded screw 116 to rotate. The threaded screw 116 can drive the two cooling fans 119 to move during the rotation, so that the cooling fans 119 can cool down different positions of the condenser 103. A collecting frame 106 is provided. The collecting frame 106 can collect the cooling water sprayed from the atomizing nozzle 113, and then the cooling water can be added to the cooling water tank 105 through the water injection hole 107. The clamping mechanism 2 can clamp the connection of the feeding pipe 104 through two arc-shaped clamping plates 204. The inner wall of the arc-shaped clamping plate 204 is provided with a rubber pad, thereby reducing the vibration of the feeding pipe 104 during condensation and reducing the possibility of leakage at the connection of the feeding pipe 104.

[0030] Working principle: first, the device is fixedly installed at the designated position. When condensation is required, the circulating water pump 109 is turned on first. The circulating water pump 109 draws the cooling water in the cooling water tank 105 into the condenser 103 through the water inlet pipe 110. The cooling water in the condenser 103 then flows into the cooling water tank 105 through the water outlet pipe 108. Then, the feed pipe 104 is connected to the output end of the previous condenser. When the material in the feed pipe 104 is condensed and cooled, the gas or liquid flowing in the feed pipe 104 may generate certain vibrations, thereby The connection between the feed pipe 104 and the previous condenser may become loose or even leak. At this time, the rotating plate 205 can be rotated, and the rotating plate 205 drives the bidirectional screw 202 to rotate. The bidirectional screw 202 drives the two arc-shaped clamping plates 204 to move closer to each other during the rotation process until the connection of the feed pipe 104 is clamped and fixed, thereby reducing the vibration of the feed pipe 104 during condensation and reducing the possibility of leakage at the connection of the feed pipe 104. After the connection is completed, the condenser 103 can condense the material in the feed pipe 104. Cooling and lowering, when the cooling water is used for a long time in a circulating cooling manner, the temperature of the cooling water may increase, resulting in a reduction in the cooling effect. In order to reduce the temperature of the cooling water in the condenser 103, the first water pump 111 can be turned on. The first water pump 111 draws water from the cooling water tank 105 into the water spray pipe 112, and then sprays the cooling water on the surface of the condenser 103 through a group of atomizing nozzles 113. The cooling water absorbs the heat on the surface of the condenser 103 and evaporates, thereby reducing the temperature of the pipe, thereby reducing the temperature of the cooling water inside the condenser 103. The two cooling fans 119 can be turned on at the same time. The wind generated by the cooling fans 119 can accelerate the evaporation of water on the surface of the condenser 103 and take away the heat, further reducing the temperature of the condenser 103, thereby further reducing the temperature of the cooling water inside the condenser 103. Then, the motor 115 is turned on. The motor 115 drives the threaded screw 116 to rotate. The threaded screw 116 can drive the two cooling fans 119 to move during the rotation, so that the cooling fans 119 can cool down different positions of the condenser 103.
