[0040] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] like Figure 1-5 As shown, a mixing condenser used for oil refining of the utility model comprises a tank body 1, a cooling pipe 2 and a nozzle 3.

[0042] The tank body 1 is used to carry other components and to realize the condensation and circulation of air. The tank body 1 includes a condensation cylinder 11, an upper head 12, an air outlet pipe 13, a lower head 14, an air inlet pipe 15, a baffle 16, a reinforcement ring 17 and a spare pipe 18.

[0043] The condensing cylinder 11 is the main structure of the tank body 1, which is arranged in a vertical direction. The upper head 12 is sealed and fixed at the top of the condensing cylinder 11. The air outlet pipe 13 is fixed on the peripheral side of the condensing cylinder 11. There are gaps between the air outlet pipe 13, the condensing cylinder 11 and the upper head 12. The air outlet pipe 13 is used to communicate with the vacuum pump, so as to draw the air entering the condensing cylinder 11 to the air outlet pipe 13. Figure 1 As shown, one end of the air outlet pipe 13 located in the condensation cylinder 11 is located in the upper right middle position of the condensation cylinder 11 , and is not continuously arranged with the interior of the condensation cylinder 11 and the upper head 12 .

[0044] The cooling pipe 2 is connected to the cooling water supply device, and the cooling pipe 2 passes through and is fixed on the upper head 12 .

[0045] The nozzle 3 is fixedly arranged at one end of the cooling tube 2 located in the condensing cylinder 11 and is connected thereto, so as to spray cooling water into the condensing cylinder 11; the end of the outlet pipe 13 located in the condensing cylinder 11 is located above the nozzle 3 and is spaced apart from the cooling tube 2; Figure 1 As shown, when the high-temperature gas in the oil refining and deodorization process enters the condensation cylinder 11 along the lower end of the condensation cylinder 11, it will come into contact with the cooling water sprayed by the nozzle 3, so that the water vapor in the high-temperature gas will liquefy, forming water droplets that fall or adhere to the inner walls of the condensation cylinder 11, the cooling tube 2 and the upper head 12, and the cooled air will be passed to the vacuum pump along the outlet pipe 13 to achieve the water vapor separation effect; during this period, since the end of the outlet pipe 13 located in the condensation cylinder 11 is not continuously arranged with the inner wall of the condensation cylinder 11, the inner wall of the upper head 12 and the outer wall of the cooling tube 2, the water droplets attached to the condensation cylinder 11, the upper head 12 and the cooling tube 2 will not flow into the outlet pipe 13, which is beneficial to improve the water vapor separation effect of the mixing condenser.

[0046] The upper end cap 12 comprises a reducer 121, an equal-diameter pipe 122 and a plugging plate 123. The lower end of the reducer 121 is sealed and fixed to the top of the condenser tube 11, and its inner diameter gradually decreases from bottom to top; the lower end of the equal-diameter pipe 122 is sealed and fixed to the top of the reducer 121; the plugging plate 123 is sealed and fixed to the top of the equal-diameter pipe 122, and the cooling pipe 2 is passed through and fixed on the plugging plate 123; in the process of the high-temperature gas moving upward in the condenser tube 11, there will be a liquefaction process, so that part of the water vapor in the high-temperature gas is liquefied and attached to the upper end cap 12. By setting the equal-diameter pipe 122 and the reducer 121, compared with the method of only setting the plugging plate 123, not only the dripping of water droplets on the upper end cap 12 can be accelerated, but also the water droplets can flow along its inner wall to the inner wall of the condenser tube 11, avoiding falling into the middle position of the condenser tube 11 to exchange heat with the high-temperature gas, and also avoiding dripping into the outlet pipe 13.

[0047] Cooling water flows in the cooling pipe 2, which can also exchange heat with the high-temperature gas to cause the water vapor in the high-temperature gas to liquefy. In order to allow the outer wall of the cooling pipe 2 to exchange heat with the high-temperature gas evenly, the cooling pipe 2 is preferably arranged coaxially with the condenser tube 11; and in order to prevent the high-temperature gas from rising or water droplets from falling directly into the outlet pipe 13, the outlet pipe 13 is preferably arranged in a horizontal direction.

[0048] like Figure 2 As shown, in order to increase the heat exchange area between the cooling tube 2 and the high-temperature air, it is preferred to provide a gap between the outer wall of the cooling tube 2 and the inner wall of the equal-diameter tube 122, and the inner diameter of the cavity between the cooling tube 2 and the upper head 12 gradually decreases, which can avoid the presence of water vapor above the device, which is beneficial to improving the liquefaction efficiency of water vapor.

[0049] like Figure 2As shown, it is preferred that the inner wall of the reducer 121 is arc-shaped, and the middle position thereof protrudes in a direction away from the center line of the reducer 121, so that the water droplets flowing into the reducer 121 from the equal-diameter tube 122 can fall at a flow speed that is first slow and then fast, thereby preventing the water droplets from detaching from the inner wall of the reducer 121.

[0050] The lower head 14 is used to discharge water in the device. The lower head 14 is sealed and fixed at the lower end of the condensation cylinder 11, and a water outlet 101 is opened inside it. The liquefied water droplets and the cooling water after heat exchange with the cooling water are discharged along the water outlet 101; grease will also be dissolved in the condensed water, so the water outlet 101 can be connected to other equipment for grease refining to recycle the grease.

[0051] The air inlet pipe 15 is used to be connected to the exhaust port of the deodorization equipment, and is used to supply high-temperature gas used in the oil refining and deodorization process to the interior of the device. The air inlet pipe 15 is fixedly arranged on the peripheral side of the condensation cylinder 11 and is connected to the interior thereof. The air inlet pipe 15 is located below the nozzle 3. After the high-temperature gas enters the condensation cylinder 11 through the air inlet pipe 15, it can exchange heat with the cooling water sprayed from the upper nozzle 3.

[0052] like Figure 1 As shown, it is preferred that the lower head 14 and the upper head 12 have the same shape and are arranged relative to each other, that is, the lower head 14 also has a diameter change process, allowing water or water droplets to flow smoothly into the water outlet 101, which is conducive to draining the moisture in the tank body 1.

[0053] The baffle 16 is fixedly arranged in the lower head 14 and is in the same plane as the center line of the condenser cylinder 11 and the center line of the air inlet pipe 15. On the one hand, the baffle 16 can strengthen the structural strength of the lower head 14. On the other hand, the baffle 16 can block the water in the lower head 14 to prevent it from swirling and causing vibration or other impacts on the device. In order to avoid the baffle 16 blocking the water outlet 101 and reducing the cross-section of the water outlet 101, thereby affecting the drainage efficiency, it is preferred that one end of the baffle 16 is located in the water outlet 101 and does not penetrate the water outlet 101.

[0054] The reinforcement ring 17 is fixedly arranged in the condenser tube 11 and is located between the nozzle 3 and the air inlet pipe 15, which can also play the role of strengthening the structural strength of the condenser tube 11; at the same time, it is preferred that the reinforcement ring 17 is circular in shape when viewed from above, and the height of the top side thereof gradually decreases from the center line of the condenser tube 11 to the side wall of the condenser tube 11, and a water hole 102 is provided in the reinforcement ring 17; Figure 3 As shown, the reinforcing ring 17 is formed into a cone-like structure. By utilizing this height difference setting, it is not only possible to avoid affecting the upward flow of high-temperature gas, but also to avoid the accumulation of cooling water and condensed water droplets, and allow the condensed water droplets and cooling water to flow along the inner wall of the condensation tube 11.

[0055] The spare pipe 18 is used to monitor various indicators in the tank body 1, or to replace the outlet pipe 13 for exhaust. The spare pipe 18 is fixedly arranged on the peripheral side of the condensing cylinder 11 and is connected to the inside thereof, and the center line of the spare pipe 18 is located on the same horizontal plane as the center line of the outlet pipe 13; Figure 4 As shown, the air outlet pipe 13, the air inlet pipe 15 and the spare pipe 18 can be arranged at staggered angles to reduce interference between them.

[0056] The working principle of a mixing condenser used in oil refining of the utility model is as follows:

[0057] The cooling pipe 2 is connected to the cooling water supply device, the air outlet pipe 13 is connected to the vacuum pump, the air inlet pipe 15 is connected to the exhaust port of the deodorizing device, and the water outlet 101 is connected to other devices, such as Figure 1 As shown, the high-temperature gas first enters the condensation cylinder 11 through the air inlet pipe 15, and exchanges heat with the cooling water sprayed by the nozzle 3 to liquefy the water vapor and oil in the high-temperature gas, and flows into other equipment through the water outlet 101 along with the cooling water, while the cooled air is drawn out along the air outlet pipe 13 by the vacuum pump; during this period, since there is a gap between the inner end of the air outlet pipe 13 and other components, the inflow of condensed water can be avoided, thereby improving the water vapor separation effect of the condenser.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
