Description

Technical Field

[0001] The utility model relates to a separation device, in particular to a separation tank for furfuryl alcohol reaction liquid. Background Art

[0002] The furfuryl alcohol dehydrogenation reaction liquid contains a small amount of hydrogen. After cooling, gas-liquid separation is performed and the separated hydrogen is reused. At present, the separation is mainly carried out through hollow tanks. The liquid enters the bottom of the hollow tank, and the hydrogen rises to the top and is discharged from the tank. During the separation process, a small amount of furfuryl alcohol and catalyst will be carried in the hydrogen, which will adhere to the pipeline, resulting in incomplete hydrogen separation and consumption of a small amount of furfuryl alcohol and catalyst, which is not conducive to subsequent processing and use. Utility Model Content

[0003] In order to solve the above problems, the utility model aims to provide a separation tank for furfuryl alcohol reaction liquid.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a separation tank for furfuryl alcohol reaction liquid, including a storage tank and a temporary storage barrel body, the storage tank is connected to the top of the temporary storage barrel body through a feeding pump, an overflow pipe connected to the storage tank is arranged on one side of the top of the temporary storage barrel body, a regulating valve is arranged on the side above the bottom of the temporary storage barrel body, the top of the temporary storage barrel body is also connected to the top of the storage tank through a balancing pipe, and a feeding pipe is arranged on the top of the storage tank.

[0005] Furthermore, a liquid level gauge is provided on one side of the storage tank and the temporary storage barrel.

[0006] Furthermore, a drain valve for emptying is provided on one side of the bottom of the storage tank.

[0007] Furthermore, the temporary storage barrel is arranged vertically, the storage tank is arranged horizontally, and the volume of the storage tank is much larger than that of the temporary storage barrel.

[0008] Furthermore, the lower end of the temporary storage barrel is connected to the upper end of the storage tank through a drain pipe.

[0009] When the utility model separates hydrogen from the furfuryl alcohol dehydrogenation reaction liquid, the hydrogen is sprayed out through the feed pipe and the spiral bend pipe. Since the liquid outlet of the spiral bend pipe is closely attached to the upper edge of the lower liquid outlet and enters along the tangent line of the upper edge of the lower liquid outlet, the liquid moves downward in a spiral on the inner side wall of the funnel-shaped lower liquid outlet, thereby facilitating the liquid to flow downward, and the separated hydrogen is discharged through the central gas outlet pipe, thereby improving the separation effect of the reaction liquid and the hydrogen, and the separation is more thorough.

[0010] In addition, when cleaning is required, the flushing pipe is connected to clean water, and the clean water is evenly sprayed from multiple nozzles of the hollow disc, thereby evenly flushing the inner wall of the lower liquid port, and the cleaning liquid is more thorough. BRIEF DESCRIPTION OF THE DRAWINGS
