AI Technical Summary

Technical Problem

In the three-tower purification system, due to the unstable system pressure during the molecular sieve purge, the gas flow rate is unstable, making it difficult to evaporate and take away the moisture within a specified time, affecting the regeneration effect of the desiccant.

Method used

A flow-based desiccant regeneration control device is designed, including a mass flowmeter, a bend, an air expansion port, a mounting frame, a fan blade and a closure device. By monitoring the gas flow and controlling the regenerated gas volume, the gas is evenly blown to the surface of the molecular sieve. And when not in use, the air expansion port is closed to avoid airflow inflow.

Benefits of technology

A more stable gas flow rate and more uniform gas blowing are achieved, which improves the regeneration effect of the desiccant and avoids the extended desiccant regeneration time and gas flow in series caused by unstable system pressure.

Abstract

The utility model discloses a drying agent regeneration control device based on flow, which relates to the technical field of electrolytic hydrogen production, and comprises a drying tank and a cooling tank, the upper surface of the drying tank is communicated with a connecting pipe, the other end of the connecting pipe is communicated with the cooling tank, the side surface of the drying tank is communicated with an air inlet pipe, and the air inlet pipe is communicated with an air outlet pipe. The side face of the drying tank is communicated with an air outlet pipe and a ventilation pipe, the inner wall of the drying tank is fixedly connected with a molecular sieve, a control regeneration device is arranged in the drying tank and comprises a mass flow meter, and the mass flow meter is installed on the surface of the ventilation pipe. The end, close to the drying tank, of the ventilation pipe communicates with a bent pipe. According to the drying agent regeneration control device based on the flow, the problem that in the process of purging a molecular sieve, due to the fact that the system pressure is not very stable, the gas flow is prone to being unstable, and water is difficult to evaporate and take away within the set time is solved.
