[0002] A condenser is a crucial piece of equipment in chemical production processes. Its function is to cool high-temperature, high-pressure gases or vapors into liquids. It works by utilizing the principles of heat conduction and mass transfer. The gas or vapor requiring cooling is transported through pipes to the condenser, where it exchanges heat with a cooling medium, lowering its temperature and causing it to condense into a liquid.

[0003] Silicon carbide is a commonly used material for heat exchange tubes. Silicon carbide condensers are widely used in petrochemical, power, metallurgy, and environmental protection fields, improving energy efficiency, reducing energy waste, and lowering production costs. Currently, the condensing efficiency of conventional silicon carbide condensers generally needs improvement. Therefore, developing more efficient silicon carbide condensers has become a technical problem that needs to be solved. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A silicon carbide condenser includes a shell, with tube sheets connected to both sides of the shell. Several heat exchange tubes are connected to both tube sheets. A flow guide rod is inserted into each heat exchange tube. One end of the flow guide rod inside the heat exchange tube is a spiral blade. The length of the spiral blade is equal to the inner diameter of the heat exchange tube. The spiral blade is in contact with the inner wall of the heat exchange tube. An air inlet box and a liquid collection box are respectively connected to the ends of the two tube sheets away from the shell.

[0008] The present invention is further configured such that: a baffle plate is fixed inside the liquid collection tank, the baffle plate is perpendicular to the liquid spray nozzle, the baffle plate is spaced apart from the outlet of the liquid spray nozzle, the side of the baffle plate facing the sealing plate does not contact the sealing plate, and the side of the baffle plate away from the sealing plate does not contact the tank body.

[0009] The present invention is further configured such that: a plurality of cooling fins are provided inside the cooling tank, the cooling fins are arranged in an inclined direction, one end of the cooling fins extends obliquely downward toward the axis of the cooling tank, and a ventilation space is provided between the plurality of cooling fins.

[0011] The present invention is further configured such that: the pipe shell is provided with an inlet and an outlet, the inlet is located at the end of the pipe shell near the liquid collection tank, and the outlet is located at the end of the pipe shell near the air inlet tank.

[0012] The advantages of this utility model are:

[0013] 1. A flow guide rod is inserted into the heat exchange tube. One end of the flow guide rod inside the heat exchange tube is a spiral blade. The length of the spiral blade is equal to the inner diameter of the heat exchange tube. That is, the spiral blade extends along the inner wall of the heat exchange tube.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A silicon carbide condenser includes a shell 1, with tube sheets 4 connected to both sides of the shell 1. Several heat exchange tubes 5 are connected to the two tube sheets 4. An air inlet box 2 and a liquid collection box 3 are respectively connected to the ends of the two tube sheets 4 away from the shell 1. The shell 1 is provided with a water inlet 11 and a water outlet 12. The water inlet 11 is located at the end of the shell 1 near the liquid collection box 3, and the water outlet 12 is located at the end of the shell 1 near the air inlet box 2. Cooling water enters from the water inlet 11, exchanges heat with the heat exchange tubes 5, and flows out from the water outlet 12. Gas is dispersed from the air inlet box 2 into the heat exchange tubes 5, undergoes heat exchange in the heat exchange tubes 5, condenses into liquid, and is finally collected and discharged through the liquid collection box 3, forming the basic structure of the condenser.

[0026] A flow guide rod 6 is inserted into the heat exchange tube 5. One end of the flow guide rod 6 inside the heat exchange tube 5 is a spiral blade 61. The blade length of the spiral blade 61 is equal to the inner diameter of the heat exchange tube 5. The spiral blade 61 is in contact with the inner wall of the heat exchange tube 5. That is, after the gas enters the heat exchange tube 5, it can only move along the extension direction of the spiral blade 61. The gas flow direction is forcibly changed, which intensifies the internal collision and dispersion of the gas, increases the contact rate between the gas and the heat exchange tube 5, and improves the efficiency of heat exchange. At the same time, the gas moves along the spiral, which increases the gas flow path, prolongs the heat exchange time, and improves the condensation effect.

[0027] One end of the spiral blade 61 is provided with a top plate 62, which abuts against one end of the heat exchange tube 5. The top plate 62 is inside the air inlet box 2. A threaded sleeve 63 is provided on the top plate 62. One end of the heat exchange tube 5 extends into the air inlet box 2. The threaded sleeve 63 is threadedly connected to the heat exchange tube 5, which can fix the guide rod 6 inside the heat exchange tube 5 and prevent the guide rod 6 from shifting under gas impact.

[0028] A baffle can be installed at another opening of the heat exchange tube 5 away from the top plate 62. The baffle is fixed above the heat exchange tube 5 and can prevent the guide rod 6 from coming out of the heat exchange tube 5 without affecting the outflow of the condensed liquid.

[0029] The liquid collection tank 3 is covered by a sealing plate 33 on the side facing the tube sheet 4. The sealing plate 33 divides the liquid collection tank 3 into two parts. One part of the liquid collection tank 3 is connected to the heat exchange tube 5. The bottom of the other part of the liquid collection tank 3 is provided with a drain port 32 and the top is provided with a cooling tank 36. Several spray nozzles 34 are provided on the sealing plate 33. One end of the spray nozzle 34 is connected to the heat exchange tube 5, and the other end of the spray nozzle 34 extends upward at an angle away from the heat exchange tube 5. The liquid generated by condensation flows out of the heat exchange tube 5 and accumulates on the right side of the sealing plate 33. Then it is sprayed out to the upper left through the spray nozzle 34 to facilitate gas-liquid separation.

[0030] A baffle plate 35 is fixed inside the liquid collection tank 3. The baffle plate 35 is perpendicular to the liquid spray nozzle 34. The baffle plate 35 and the outlet of the liquid spray nozzle 34 are spaced apart. The side of the baffle plate 35 facing the sealing plate 33 does not contact the sealing plate 33, and the side of the baffle plate 35 away from the sealing plate 33 does not contact the tank body 31. After the liquid generated by condensation is sprayed out, it falls on the baffle plate 35 and collides. After the liquid collides, it is dispersed. The liquid sinks due to its own weight. A small amount of gas rises through the gap between the baffle plate 35 and the sealing plate 33 and finally enters the cooling tank 36 to be cooled into liquid. This reduces the gas content in the final output fluid and improves the condensation effect.

[0031] The cooling tank 36 is provided with several cooling fins 37, which are arranged at an angle. The end of the cooling fins 37 facing the axis of the cooling tank 36 extends obliquely downward. There is a ventilation space between the cooling fins 37, and the rising gas can be dispersed between the cooling fins 37 through the ventilation space. The cooling fins 37 are in contact with the outside through the tank body of the cooling tank 36. The gas cools naturally at room temperature and eventually condenses into liquid on the surface of the cooling fins 37. The liquid drips down the surface of the cooling fins 37 and is discharged through the drain port 32.

[0032] Specifically, a guide rod 6 is inserted into the heat exchange tube 5. One end of the guide rod 6 inside the heat exchange tube 5 is a spiral blade 61. The blade length of the spiral blade 61 is equal to the inner diameter of the heat exchange tube 5. That is, the spiral blade 61 extends along the inner wall of the heat exchange tube 5. When the gas enters the heat exchange tube 5, it can only move forward spirally along the extension direction of the spiral blade 61. This can repeatedly change the gas flow direction, improve the contact rate between the gas and the heat exchange tube 5, extend the gas flow path, and thus improve the condensation efficiency.

[0033] A sealing plate 33 is installed inside the liquid collection tank 3. The condensed liquid is sprayed onto the baffle plate 35 through the spray nozzle 34 on the sealing plate 33. After impact, the liquid sinks due to its own weight and is discharged from the drain port 32. Meanwhile, a small amount of gas rises and eventually enters the cooling tank 36 above. The gas is naturally cooled into liquid in the cooling tank 36 and drips down, which is discharged through the drain port 32. This reduces the gas content in the final condensate and improves the cooling effect.
