Description

TECHNICAL FIELD

[0001] The application relates to the technical field of liquid fuel preparation, and particularly relates to a denatured fuel ethanol mixing device. BACKGROUND

[0002] In recent years, ethanol gasoline has been widely concerned and applied as an environmentally friendly fuel. Among them, denatured fuel ethanol, as an important component of ethanol gasoline, is produced by special equipment through a specific process and cannot be used after denaturation treatment, but is only used for mixing gasoline. The addition of denatured fuel ethanol can significantly improve the octane number of gasoline and improve its combustion efficiency.

[0003] In order to realize effective mixing of ethanol and gasoline, a Chinese utility model patent with the authorization announcement number CN220310193U discloses an ethanol gasoline blending device. The device adopts a molecular sieve permeation vaporization membrane technology, can effectively separate water molecules in ethanol, significantly reduces the liquid phase separation, and thus improves the practicability and quality of ethanol gasoline. In addition, the device is also provided with a stirring assembly, which improves the mixing efficiency of ethanol and gasoline through stirring, and ensures the smooth progress of the blending process.

[0004] However, in the process of stirring ethanol and gasoline, if the stirring intensity is too large or the stirring time is too long, physical damage such as scratches, abrasion or tearing may be caused to the surface of the molecular sieve permeation vaporization membrane. These damages not only destroy the integrity of the membrane surface, but also seriously affect the separation performance of the membrane, leading to the decrease of the quality of ethanol gasoline.

[0005] In addition, the turbulence generated in the stirring process may also cause scouring effect on the membrane holes, leading to deformation or expansion of the pore size of the membrane holes. Such changes will reduce the separation selectivity of the membrane, so that substances that cannot pass through the membrane holes can pass through, further affecting the blending effect and quality of ethanol gasoline.

[0006] Therefore, the application provides a denatured fuel ethanol mixing device to solve the above problems. CONTENT OF THE UTILITY MODEL

These damages not only destroy the integrity of the membrane surface, but also seriously affect the separation performance of the membrane, leading to the decrease of the quality of ethanol gasoline.

At this time, the stirring structure is started to generate vortex to promote the rapid and uniform mixing of gasoline and ethanol. After mixing is completed, the denatured fuel ethanol is discharged through the liquid outlet for subsequent use.

[0009] Preferably, the filter pipe is in the shape of a tapered pipe, and the small-diameter end of the filter pipe is fixedly connected to the second liquid inlet. The tapered pipe-shaped filter pipe can accelerate the flow rate of ethanol flowing into the second liquid inlet.

Through real-time monitoring of the liquid flow by the flow sensor and precise control of the electromagnetic valve by the controller, accurate regulation of the mixing ratio of the denatured fuel can be achieved, ensuring the stability and consistency of product quality.

[0014] The application can separate water molecules in ethanol while avoiding the direct impact of the vortex generated by the stirring structure on the molecular sieve pervaporation membrane during mixing of denatured fuel ethanol by arranging the filter structure for separating water in denatured fuel ethanol outside the tank, i.e. arranging the molecular sieve pervaporation membrane inside the second liquid injection port. The service life of the molecular sieve pervaporation membrane is prolonged. Through the filtering effect of the molecular sieve pervaporation membrane, water in ethanol is effectively removed, improving the quality of denatured fuel ethanol.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a denatured fuel ethanol mixing device, such as Figures 1-3 As shown, the mixing device includes a tank 1, a first injection port 11 located at the top of the tank 1, an outlet port 12 located at the bottom of the tank 1, and a stirring structure located inside the tank 1 for mixing denatured fuel ethanol. It also includes a second injection port 13 located at the upper end of the tank 1 and a filter structure 2 located on the second injection port 13 for filtering the denatured fuel ethanol. The filter structure 2 includes a filter tube 21 fixedly connected to the second injection port 13 and a molecular sieve pervaporation membrane 22 fixedly installed inside the filter tube 21. By placing the filter structure 2 for separating water in the denatured fuel ethanol outside the tank 1, that is, placing the molecular sieve pervaporation membrane 22 inside the second injection port 13, water molecules in the ethanol can be separated while avoiding the direct impact of the eddies generated by the stirring structure during mixing of the denatured fuel ethanol on the molecular sieve pervaporation membrane 22, thus extending the service life of the molecular sieve pervaporation membrane 22. Through the filtration effect of the molecular sieve pervaporation membrane 22, water in the ethanol is effectively removed, improving the quality of the denatured fuel ethanol. In use, gasoline is first injected into tank 1 through the first injection port 11. Then, ethanol is injected through the second injection port 13. After entering the filter tube 21, the ethanol passes through the molecular sieve pervaporation membrane 22, effectively separating the water, while the pure ethanol continues to flow into tank 1. At this point, the stirring structure is activated, generating a vortex to promote rapid and uniform mixing of gasoline and ethanol. After mixing is complete, the denatured fuel ethanol is discharged through the outlet 12 for subsequent use.

[0024] Among them, a drain pipe is provided above the molecular sieve pervaporation membrane 22 corresponding to the filter tube 21.

[0025] The filter tube 21 is a conical tube, and its smaller diameter end is fixedly connected to the second injection port 13. The conical filter tube 21 can accelerate the flow rate of ethanol into the second injection port 13.

[0026] Specifically, in order to facilitate the fixation of the molecular sieve pervaporation membrane 22 inside the filter tube 21, the inside of the filter tube 21 is fixedly connected with a fixing ring 211, and the molecular sieve pervaporation membrane 22 is fixedly provided with a mounting ring 221, which is fixedly mounted on the fixing ring 211 by bolts. The installation by bolts is simple in operation and facilitates the installation and disassembly of the molecular sieve pervaporation membrane 22.

[0027] More specifically, in order to improve the sealing between the mounting ring 221 and the filter tube 21, the mounting ring 221 is provided with a sealing ring 2211 for sealing the gap between the mounting ring 221 and the filter tube 21. The sealing ring 2211 is made of rubber material, and the elasticity of the sealing ring 2211 can seal the gap between the mounting ring 221 and the filter tube 21.

[0028] In order to facilitate the replacement of the molecular sieve pervaporation membrane 22 inside the filter tube 21, the upper end of the filter tube 21 is fixedly provided with an access cover 212 by bolts, and the upper end of the access cover 212 is provided with a third liquid inlet 2121. When the molecular sieve pervaporation membrane 22 needs to be replaced, the access cover 212 can be removed, and the molecular sieve pervaporation membrane 22 can be removed from the inside of the filter tube 21. The access cover 212 and the filter tube 21 are provided with a rubber sealing gasket.

[0029] Embodiment 2

[0030] Different from embodiment 1, in order to facilitate the monitoring and control of the liquid injected into the tank 1 from the first liquid inlet 11 and the second liquid inlet 13, the tank 1 is provided with a controller 3, the first liquid inlet 11 and the second liquid inlet 13 are provided with electromagnetic valves 31 connected with the controller 3, and the inside of the first liquid inlet 11 and the second liquid inlet 13 are provided with flow sensors 32 connected with the controller 3. Through the real-time monitoring of the liquid flow by the flow sensor 32 and the accurate control of the electromagnetic valve 31 by the controller 3, the precise regulation of the mixed ratio of the denatured fuel can be realized, and the stability and consistency of the product quality can be ensured. During the operation, the user first presets the required mixed ratio of the denatured fuel through the controller 3. Then, when the gasoline is injected into the first liquid inlet 11, the flow sensor 32 detects the flow of the gasoline in real time and feeds back the data to the controller 3. The controller 3 calculates the time when the electromagnetic valve 31 should be opened according to the preset ratio and the real-time flow data, so as to control the injection amount of ethanol from the second liquid inlet 13. Similarly, the injection amount of ethanol is also monitored and controlled in real time by the flow sensor 32. When the two kinds of liquid are injected into the tank 1 according to the preset ratio, the stirring structure starts to work to promote the rapid and uniform mixing of gasoline and ethanol. After the mixing is completed, the denatured fuel ethanol is discharged through the liquid outlet 12 for subsequent use. During the whole process, the controller 3 continuously monitors the flow.

[0031] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and concept of the present application, can make equivalent replacements or changes within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
