Description

Technical Field

[0001] The invention relates to the technical field of hydrogen washing, in particular to a hydrogen washing tower and a washing method. Background Art

[0002] Hydrogen chloride is produced by a chemical reaction in which chlorine and hydrogen enter the synthesis furnace in a certain ratio and stably burn at the lamp head of the synthesis furnace. In the ion membrane alkali production process, hydrogen is sent out from the cathode chamber of the electrolyzer, and this hydrogen contains alkali vapor; the alkali vapor carried by the incompletely washed hydrogen will react with the chlorine to generate salts that are enriched at the lamp head, affecting the normal flow of hydrogen and causing the chemical reaction to be unstable. It also affects the quality of hydrogen chloride and brings great hidden dangers to production safety. At present, the hydrogen washing process adopts in-tower washing and circulates through a circulating pump. Due to insufficient flow of washing liquid, the hydrogen washing effect is poor. After washing, the hydrogen contains more impurities such as salt and alkali, which reduces the quality of hydrogen chloride and causes the flame arrester and lamp head of the hydrogen chloride synthesis furnace in the subsequent system to be frequently blocked and burned. The maintenance workload is large and the maintenance cost increases, which seriously affects the safe and stable operation of the production system. For this reason, we propose a hydrogen washing tower and washing method. Summary of the invention

[0012] A washing method for a hydrogen washing tower comprises the following steps:

[0013] S1: The water pump draws the hydrogen washing liquid in the liquid collecting chamber and delivers it to the liquid outlet chamber in the fixed seat through the delivery pipe, and then flows into the top of the central spinning plate. Under the rotation of the central spinning plate, the hydrogen washing liquid on it is poured out;

[0014] S2: Most of the hydrogen scrubbing liquid thrown out and spilled by the central spinner falls on the external spinner, and then, under the drive of the third motor output shaft and the transmission belt, all the external spinners can rotate, and the external spinners can spill the hydrogen scrubbing liquid that falls on the external spinner in a fan shape, so as to ensure that the hydrogen scrubbing liquid can be fully and evenly sprinkled from the tower body of the scrubbing tower;

[0015] S3: The hydrogen scrubbing liquid poured down falls on the water curtain guide plate, and the hydrogen scrubbing liquid flows downward through the top of the water curtain guide plate, and flows to the top of the water curtain guide plate of the next layer, so that a water curtain can be formed between the water curtain guide plates, and through the continuous diversion of the water curtain guide plates, multiple and multi-layer water curtains can be formed;

[0016] S4: The hydrogen enters the inside of the scrubber through the air inlet and passes through the filling port. Driven by the output shaft of the second motor, the turbine wheel rotates, and the hydrogen passing through the filling port moves upward in a spiral shape;

[0017] S5: Hydrogen passes through the water curtain between the water curtain guide plates, through the water layer sprinkled by the external spinner, and finally completes the washing, and then is discharged through the outlet.

[0018] The present invention has the following beneficial effects:

[0019] 1. The hydrogen scrubbing tower and the scrubbing method enable the hydrogen scrubbing liquid thereon to be poured out horizontally and form multiple water layers through the rotation of the central spinner and the external spinner, so that when the hydrogen moves upward, it can be washed by the water layer and washed again, thereby ensuring the washing quality of the hydrogen. Furthermore, through the rotation and pouring of the multiple external spinners and the central spinner, the hydrogen scrubbing liquid can be relatively evenly sprinkled in the tower body of the scrubbing tower, thereby making the washing of the hydrogen more sufficient.

[0020] 2. The hydrogen scrubbing tower and the scrubbing method are characterized in that the hydrogen scrubbing liquid is poured onto the water curtain guide plate, and the hydrogen scrubbing liquid flows downward through the top of the water curtain guide plate and flows to the top of the water curtain guide plate of the next layer, so that a water curtain can be formed between the water curtain guide plates, and multiple and multi-layer water curtains can be formed through the continuous diversion of the water curtain guide plates, so that the hydrogen must pass through the water curtains between the water curtain guide plates before it can be discharged upward, thereby ensuring that the hydrogen is washed more fully.

[0021] 3. The hydrogen scrubbing tower and scrubbing method enable the turbine impeller to rotate under the drive of the second motor output shaft. Under the rotation of the turbine impeller, the hydrogen can move upward in a spiral vortex, thereby extending the movement path of the hydrogen and allowing the hydrogen to stay in the scrubbing tower body for a longer time, thereby more fully scrubbing the hydrogen.
