[0002] As an impurity in petroleum, asphaltene is a complex mixture composed of a variety of complex high-molecular hydrocarbons and their non-metallic derivatives. It has a significant impact on the quality of petroleum products, especially in the deep processing of petroleum. There are many methods for measuring the content of asphaltene, such as the method disclosed in CN200110084098.X, the TLC-PID method and the distillation method. The distillation method is the simplest method to detect the content of asphaltene in petroleum, such as the patent with application number 201720391817.5. However, hydrocarbon contamination gas will be generated during the distillation process, and the distilled part is exposed to the air, which has a poor heating effect on the distillation flask, and the generated gas cannot be detected.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3This embodiment provides an environmentally friendly automatic asphaltene distillation device, including a box body 1, an inner box 5 is fixedly installed inside the box body 1, a heating device is provided at the bottom of the inner box 5, and a distillation flask 3 is placed in the inner box 5. The heating device can heat the distillation flask 3, and the heating device is preferably a constant temperature electric heating device that can control the temperature. The inner box 5 separates the distillation flask 3 from the box body 1, and seals the distillation flask 3 in an independent cavity. The inner box 5 has a heat preservation effect. When the distillation flask 3 is heated, it can ensure that the temperature of the entire distillation flask 3 is in a constant temperature state, thereby improving the heating effect of the distillation flask 3.

[0020] Preferably, a placement groove for placing the distillation flask 3 is provided at the bottom of the inner cavity of the inner box 5. The height of the placement groove exceeds half of the distillation flask 3. The placement groove also has the function of heat preservation for the distillation flask 3 and can make the distillation flask 3 be placed more stably.

[0021] In a further embodiment, Figure 4 As shown, in order to facilitate the placement of the distillation flask 3, an open structure is provided on one side of the placement slot, and a clamping plate 51 is installed at the opening structure. The clamping plate 51 can be directly installed in the opening structure to limit the distillation flask 3.

[0022] When distilling liquid, the distillation flask 3 can be preheated first, and the preheating temperature is within 50-70 degrees Celsius, so that the gas or residual water in the distillation flask 3 can be fully volatilized, and then liquid can be slowly added from the connecting pipe 4 to increase the temperature for heating.

[0023] The distillation flask 3 is connected to the condenser 2 through a pipeline. The outer ends of the condenser 2 are respectively provided with a cold water inlet and an outlet, and water pipes are installed at the cold water inlet and outlet. The water pipes pass through the top of the box body 1 and are exposed on the outside of the box body 1. The water pipes also support the condenser.

[0024] The other end of the condenser 2 is connected to the receiving bottle 6 through a pipeline. A vent pipe is installed at the bottle mouth of the receiving bottle 6. The vent pipe is used to discharge the gas in the receiving bottle 6, and a gas treatment device 8 is installed at the end of the vent pipe; the gas treatment device 8 is installed with an activated carbon layer, an activated alumina layer, a silica gel layer or a molecular sieve, which is used to remove hydrocarbon gases in the gas to ensure that the discharged gas is pollution-free.

[0025] A connecting pipe 4 is fixedly installed at the bottom of the distillation flask 3. The connecting pipe 4 passes through the inner box 5 and the side wall of the box body 1. The external part of the connecting pipe 4 is vertically arranged, and its top is higher than the top of the distillation flask 3. A sealing plug is arranged on the top of the connecting pipe 4.

[0026] The connecting tube 4 can directly add liquid to the distillation flask 3. When adding liquid, the sealing plug is directly removed and the liquid is added from the top of the connecting tube 4. Due to the communicating vessel principle, the liquid will enter the distillation flask 3. After the addition is completed, the top of the connecting tube 4 needs to be sealed with a sealing plug to prevent gas leakage during the heating process.

[0027] A funnel is fixedly installed on the top of the connecting pipe 4, the side wall of the funnel is provided with threads, and the bottom of the funnel is a conical structure. A sealing plug 32 is placed in the funnel, and the side of the sealing plug 32 is also provided with threads. The bottom of the sealing plug 32 is set to a sloped structure and matches the bottom of the funnel. When the sealing plug 32 is installed in the funnel, under the action of the threads, the bottom of the sealing plug 32 will be squeezed with the bottom of the funnel, thereby achieving a better sealing effect.

[0028] The connecting tube 4 can also be used to display the height of the liquid in the distillation flask 3, and can be used to observe the amount of liquid in the distillation flask 3 and control the heating time. However, since the top of the connecting tube 4 is sealed, gas will enter the top of the connecting tube 4 during heating, which will cause inaccurate observation. Therefore, in a further embodiment, Figure 3 As shown, the upper end of the connecting tube 4 is also provided with a connecting tube 31 connected to the top of the distillation flask 3, so that the top of the connecting tube 4 is connected to the top of the distillation flask 3, which can ensure that the air pressure in the connecting tube 4 is consistent with the air pressure in the distillation flask 3, and can more accurately indicate the height of the liquid in the distillation flask 3.

[0029] In a further embodiment, a mounting groove for installing the gas processing device 8 is provided on the outer side of the box body 1, and the end of the ventilation pipe extends into the side wall of the mounting groove. The gas processing device 8 and the mounting groove are both cylindrical structures, and the side wall of the mounting groove and one end of the gas processing device 8 are provided with threads. The gas processing device 8 is directly installed in the mounting groove through the threads. The gas in the ventilation pipe enters the mounting groove, then flows into the gas processing device 8, and is discharged from the other end of the gas processing device 8.

[0030] Moreover, the gas processing device 8 can be directly taken out from the installation slot, which is convenient for replacing the gas processing device 8. This avoids the problem that the ventilation pipe is directly connected to the gas processing device 8, which makes it inconvenient to replace the gas processing device 8.

[0031] In addition, the ventilation pipe is connected to a detection air pipe 7. When not in use, the detection air pipe 7 is sealed with a rubber stopper. When the gas needs to be tested, the detection air pipe 7 only needs to be extended into the gas cylinder to collect the gas. Moreover, since the gas processing device 8 is provided with a multi-layer structure and has a certain resistance, when the detection air pipe 7 is opened, the gas will be discharged from the detection air pipe 7 first.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
