Description

TECHNICAL FIELD

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

[0002] As a high-purity anhydrous alcohol, denatured fuel ethanol is very important in the impurity purification process. At present, the process mainly adopts distillation. The existing distillation purification device mainly comprises a distillation tank, a condenser, a liquid guide pipe and a collection tank. The distillation tank is used for heating and distilling raw materials, the generated steam is cooled into liquid through the condenser, and then is guided out through the liquid guide pipe and finally flows into the collection tank for collection.

[0003] However, in the actual use process, the liquid concentration generated in the initial distillation stage is low, and only when the distillation temperature reaches a certain degree, high-purity liquid can be produced. This means that different collection tanks need to be used to collect liquids with different concentrations in the distillation process. In the process of replacing the collection tank, there is often residual liquid in the liquid guide pipe. These liquids are easy to drop to the ground, which not only causes environmental pollution, but also leads to waste of valuable liquid resources.

[0004] Therefore, the application provides a denatured fuel ethanol impurity purification device to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The application provides a denatured fuel ethanol impurity purification device, which aims to solve the problems that the liquid concentration generated in the initial distillation stage is low, and only when the distillation temperature reaches a certain degree, high-purity liquid can be produced. This means that different collection tanks need to be used to collect liquids with different concentrations in the distillation process. In the process of replacing the collection tank, there is often residual liquid in the liquid guide pipe. These liquids are easy to drop to the ground, which not only causes environmental pollution, but also leads to waste of valuable liquid resources.

In use, first, the denatured fuel ethanol raw material is put into the distillation tank for heating distillation. The generated steam is cooled by the condenser pipe and flows into the liquid guide pipe after being converted into liquid. At this time, because the concentration of the liquid generated in the initial stage of distillation is low, the liquid flows into the first collection tank through the first shunt pipe for collection.

In this way, through the cooperation of the first shunt pipe and the second shunt pipe, effective collection of liquid with different concentrations can be realized without replacing the collection tank, thereby improving the purification efficiency and resource utilization rate.

The cooperation of the control box and the electromagnetic valve facilitates the opening and closing of the first shunt pipe and the second shunt pipe.

[0008] Preferably, a thorn-shaped fractional column is fixedly arranged at the upper end of the distillation tank, and the thorn-shaped fractional column is communicated with the condenser pipe through a second three-way pipe.

[0009] Preferably, in order to facilitate the observation of the temperature of the steam, a temperature sensor is arranged on the second three-way pipe, and the temperature sensor is connected with the control box. The temperature sensor facilitates real-time monitoring of the steam and facilitates collection of liquid with different concentrations in different collection tanks.

[0010] Preferably, in order to facilitate the support of the condenser pipe, a fixing ring is fixedly sleeved at both ends of the condenser pipe, and a support leg is fixedly connected to the bottom of the fixing ring.

[0012] Preferably, in order to facilitate heat dissipation of the liquid in the second water pipe, the second water pipe is a copper pipe, and a plurality of fins are fixedly arranged on the second water pipe at equal intervals.

[0013] The first shunt pipe and the second shunt pipe are matched to simultaneously collect liquid of different concentrations without replacing the collection tank, thereby improving the purification efficiency. The pollution and waste caused by liquid dripping to the ground during replacement of the collection tank are avoided, the resource utilization rate is improved, the liquid dripping and the replacement operation of the collection tank are reduced, and the production environment is more clean and orderly.
