Description

Technical Field

[0001] This utility model belongs to the technical field of gas-water separators, and in particular relates to a gas-water separator for methanol-to-hydrogen production. Background Technology

[0002] Hydrogen has a wide range of industrial applications, and the demand for pure hydrogen has increased rapidly in recent years. Methanol-to-hydrogen production is one of the more mature technologies currently available. In the methanol-to-hydrogen process, a vapor-water separator is needed to separate hydrogen from water vapor. A large amount of water-containing vapor enters the separator and moves downwards in a centrifugal, inclined motion. The entrained water is separated due to the reduced velocity. The separated liquid is discharged from the drain outlet, while the dry, clean vapor exits from the separator outlet.

[0003] Existing gas-water separators have simple structures but poor condensation effects, resulting in the discharged hydrogen not meeting the expected dryness requirements. Therefore, this utility model proposes a gas-water separator for methanol-to-hydrogen production. Utility Model Content

[0004] This invention provides a vapor-water separator for methanol-to-hydrogen production, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a vapor-water separator for methanol-to-hydrogen production, including a vapor-water separator box;

[0006] The outer wall of the gas-water separator is provided with an inlet pipe and an outlet pipe that are distributed opposite to each other. The top surface of the gas-water separator is provided with a cooler. The cooler outlet is connected to a cooling pipe, and the cooling pipe is connected to a cooling plate.

[0007] The gas-liquid separator is equipped with a gas-liquid separation component, which includes a separation barrel. The separation barrel is fixed to the inner wall of the gas-liquid separator near the gas outlet pipe. The top of the separation barrel is equipped with a spiral blade, which is located directly below the cooling plate. The spiral blade communicates with the internal space of the separation barrel. The bottom of the separation barrel is equipped with a flow guide tube, which has an inverted conical structure.

[0008] Preferably, the air inlet pipe is connected to the internal space of the steam-water separator, and the air outlet pipe is connected to the internal space of the separator barrel.

[0009] Preferably, the helical blades are driven by a motor.

[0010] Preferably, the spiral blades are provided in multiple ways, and the multiple spiral blades are distributed in a ring shape on the top of the separation barrel.

[0011] Preferably, the bottom of the gas-water separator is equipped with a liquid outlet valve.

[0012] Preferably, the outer wall of the gas-water separator is provided with three support legs arranged in a circular pattern.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The refrigeration unit is started to begin cooling. Cold air enters the cooling pipe through the refrigeration unit outlet and is then evenly diffused above multiple spiral blades by the cooling plate. Hydrogen containing moisture is transported to the gas-liquid separator through the air inlet pipe. The motor is started to drive the spiral blades to rotate. The rotation of the spiral blades draws in the cold air and the hydrogen containing moisture. Under the action of centrifugal force and cold air, the moisture condenses into water droplets and beads, which are then stuck on the blade walls. Under the action of centrifugal force, the water droplets and beads are thrown into the wall of the separator. Then, under the action of the guide tube, the water droplets and beads are dripped into the bottom of the gas-liquid separator. The dry hydrogen is discharged through the gas outlet pipe to enter the next process. When there is too much water at the bottom of the gas-liquid separator, the liquid outlet valve is opened to drain the water, which can be collected and reused. Attached Figure Description
