Description

Technical Field

[0001] This utility model relates to the field of crude benzene processing technology, specifically to a condenser cooler for a crude benzene processing section. Background Technology

[0002] Crude benzene is an organic mixture produced during coal processing, mainly from coke oven gas and coal tar. To achieve efficient separation in crude benzene processing, heat exchange equipment is usually used to accelerate its cooling. Refer to the relevant patent CN218646109U. Essentially, it involves setting up multiple heat exchange plates, each with an inlet pipe and an outlet pipe connected to the heat exchange medium inlet and outlet, respectively. The overall structure is easy to disassemble and clean.

[0003] The following points regarding the precautions for heat exchange operations in crude benzene processing are explained: During crude benzene processing, the temperature requirements for heat exchange operations are crucial for ensuring efficient process operation. Using high-temperature liquids for heat exchange will affect the efficiency of heat exchange and may also cause the volatilization of light components in the product, affecting the purity and properties of the product. Excessively low heat exchange water temperatures will cause crude benzene to crystallize within the pipelines, affecting the pipeline's transmission efficiency. In addition to fully realizing the use of appropriate water temperatures for heat exchange of the crude benzene solution, it is also necessary to consider the long-term operation of the device. Therefore, we provide a condenser / cooler for the crude benzene processing section to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a condenser / cooler for the crude benzene processing section to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A condenser cooler for a crude benzene processing section includes a support frame. The top surface of the support frame is provided with a fixed unit for uniform heat exchange of crude benzene in multiple sections. The output end of the fixed unit is provided with a water storage unit to maintain the water temperature at a suitable temperature.

[0007] The fixing unit includes a hot water exchange tank fixedly installed on the top surface of the bracket and a spiral tube fixedly installed inside the hot water exchange tank to increase the residence time of the crude benzene liquid;

[0008] The water storage unit includes a multi-bend water outlet pipe fixedly installed inside the bottom of the heat exchange tank to increase the water flow after heat exchange, a water tank fixedly installed at the output end of the multi-bend water outlet pipe, and a heating grid fixedly installed inside the heating grid to prevent the water temperature from being too low.

[0009] A further improvement of this utility model is that a protective frame is fixedly connected to the side of the water tank, and the protective frame is movably installed on the side of the multi-bend water outlet pipe.

[0010] A further improvement of this utility model is that: a water pump is fixedly connected to the bottom of the other side of the water tank, and an inlet pipe is fixedly connected to the output end of the water pump. The inlet pipe is fixedly installed inside the top surface of the hot water exchange tank.

[0011] A further improvement of this utility model is that: an air outlet filter is fixedly connected to the inside of the side of the water tank, a cooling fan is installed inside the air outlet filter, and the cooling fan is installed on the side of the multi-bend water outlet pipe.

[0012] A further improvement of this utility model is that: the input end of the hot water exchange tank is fixedly connected to a feed inlet, the output end of the hot water exchange tank is fixedly connected to a discharge outlet, and the feed inlet is interconnected with the spiral tube and the discharge outlet.

[0013] A further improvement of this utility model is that: a motor is fixedly connected inside the top surface of the hot water exchange tank, and a stirring plate is fixedly connected to the output end of the motor, with the stirring plate movably installed inside the hot water exchange tank.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a condenser cooler for a crude benzene processing section. The liquid inside the water tank is kept in a suitable temperature range for the heat exchange operation of crude benzene by a heating network. The liquid at a suitable temperature is transferred to the interior of a fixed unit for heat exchange operation by a water pump. After the heat exchange is completed, the high-temperature liquid is transferred to the interior of a multi-bend water outlet pipe.

[0016] The multi-bend water pipe itself increases the travel distance of the high-temperature liquid. At the same time, a cooling fan drives the airflow to remove the heat from the gas inside the multi-bend water pipe, allowing it to be cooled down to a certain range quickly. The heat is then transferred to the top surface of the water tank, where a heating grid heats the liquid to a suitable temperature, facilitating heat exchange operations.

[0017] 2. This utility model provides a condenser cooler for the crude benzene processing section. The crude benzene solution enters the interior of the spiral tube through the inlet. Under the action of the liquid driven by the water storage unit, the liquid inside the spiral tube is subjected to heat exchange. The motor drives the stirring plate to rotate, and the stirring plate quickly stirs the liquid inside the heat exchange tank to ensure that the temperature of the liquid inside the heat exchange tank is always uniform, thus ensuring that the heat exchange operation inside the spiral tube is always at the correct temperature.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1: As Figure 1-5 As shown, this utility model provides a condenser cooler for a crude benzene processing section, including a support 1. The top surface of the support 1 is provided with a fixed unit 2 for uniform heat exchange of crude benzene in multiple sections. The output end of the fixed unit 2 is provided with a water storage unit 3 to maintain the water temperature at a suitable temperature. The water storage unit 3 includes a multi-bend water outlet pipe 32 fixedly installed inside the bottom surface of the hot water tank 21 to increase the water flow after heat exchange, a water tank 31 fixedly installed at the output end of the multi-bend water outlet pipe 32, and a heating net 38 fixedly installed inside the heating net 38 to prevent the water temperature from being too low. A protective frame 33 is fixedly connected to the side of the water tank 31, and the protective frame 33 is movably installed on the side of the multi-bend water outlet pipe 32.

[0026] The middle section of the multi-bend outlet pipe 32 is designed with a multi-folded shape to increase the travel of hot water after heat exchange. It is connected to the inside of the top side of the water tank 31. The water pump 34 is fixedly installed at the bottom side of the water tank 31 and connected to the inside of the top surface of the hot water exchange tank 21 through the inlet pipe 35. The hot water exchange tank 21 and the water tank 31 are connected through the multi-bend outlet pipe 32 and the inlet pipe 35 to form a complete water circulation loop.

[0027] A water pump 34 is fixedly connected to the bottom of the other side of the water tank 31. The output end of the water pump 34 is fixedly connected to the inlet pipe 35. The inlet pipe 35 is fixedly installed inside the top surface of the water exchange tank 21. An air outlet filter 36 is fixedly connected to the inside of the side of the water tank 31. A cooling fan 37 is installed inside the air outlet filter 36. The cooling fan 37 is installed on the side of the multi-bend water outlet pipe 32.

[0028] The air outlet filter 36 protects the cooling fan 37 and generates airflow through the cooling fan 37. The airflow carries away the heat on the outer surface of the multi-bend water outlet pipe 32, which helps to reduce the heat of the liquid inside the multi-bend water outlet pipe 32. The heating net 38 can maintain the liquid inside the water tank 31 at a certain temperature.

[0029] In this embodiment, the liquid inside the water tank 31 is kept in a suitable temperature range for the crude benzene heat exchange operation by the heating net 38, and the liquid at the appropriate temperature is transported to the interior of the fixed unit 2 for heat exchange operation by the water pump 34, and the high-temperature liquid after heat exchange is transported to the interior of the multi-bend water outlet pipe 32.

[0030] The multi-bend water outlet pipe 32 has a multi-bend design, which increases the travel distance of the high-temperature liquid. At the same time, the cooling fan 37 drives the airflow to remove the temperature of the gas inside the multi-bend water outlet pipe 32, so that it can be quickly cooled to a certain range and further transferred to the inner top surface of the water tank 31. The heating net 38 heats the liquid to a suitable temperature, which facilitates heat exchange operations.

[0031] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing unit 2 includes a hot water tank 21 fixedly installed on the top surface of the bracket 1, a spiral tube 24 fixedly installed inside the hot water tank 21 to increase the residence time of the crude benzene liquid, an inlet 22 fixedly connected to the input end of the hot water tank 21, an outlet 23 fixedly connected to the output end of the hot water tank 21, the inlet 22 communicating with the spiral tube 24 and the outlet 23, a motor 25 fixedly connected inside the top surface of the hot water tank 21, a stirring plate 26 fixedly connected to the output end of the motor 25, and the stirring plate 26 being movably installed inside the hot water tank 21;

[0032] The hot water tank 21 has enough space inside to hold enough liquid. The spiral tube 24 does not directly contact the inner wall of the hot water tank 21. The spiral tube 24 is fixed by the inlet 22 and the outlet 23. The spiral tube 24 is completely wrapped around the outer surface of the stirring plate 26.

[0033] In this embodiment, the crude benzene solution enters the interior of the spiral tube 24 through the feed inlet 22. Under the action of the liquid driven by the water storage unit 3, the liquid inside the spiral tube 24 is subjected to heat exchange. The motor 25 drives the stirring plate 26 to rotate, and the stirring plate 26 quickly stirs the liquid inside the heat exchange tank 21 to ensure that the temperature of the liquid inside the heat exchange tank 21 is always uniform, and to ensure that the heat exchange operation inside the spiral tube 24 is always at the correct temperature.

[0034] The working principle of the condenser in the crude benzene processing section will be explained in detail below.

[0035] like Figure 1-5 As shown, the fixed unit 2 increases the flow path of the crude benzene solution and maintains a uniform temperature during the heat exchange process. The water storage unit 3 rapidly cools the water after heat exchange while maintaining it at a constant temperature, ensuring the device remains at a suitable temperature for the crude benzene solution heat exchange process.

[0036] The crude benzene solution enters the interior of the spiral tube 24 through the feed inlet 22. The heating net 38 keeps the liquid inside the water tank 31 within a suitable temperature range for the crude benzene heat exchange operation. Driven by the water pump 34, the liquid at the appropriate temperature is transferred to the interior of the fixed unit 2 for heat exchange operation.

[0037] Motor 25 drives stirring plate 26 to rotate, stirring plate 26 quickly stirs the liquid inside heat exchange tank 21, ensuring that the temperature of the liquid inside heat exchange tank 21 is always uniform, and ensuring that the heat exchange operation inside spiral tube 24 is always at the same temperature.

[0038] After heat exchange is completed, the high-temperature liquid is transferred to the inside of the multi-bend water outlet pipe 32. The multi-bend design of the multi-bend water outlet pipe 32 increases the travel distance of the high-temperature liquid. At the same time, the cooling fan 37 drives the airflow to remove the temperature of the gas inside the multi-bend water outlet pipe 32, so that it can be quickly cooled to a certain range and further transferred to the inner top surface of the water tank 31. The heating mesh 38 heats the liquid to a suitable temperature to facilitate heat exchange.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
