High pressure dehydration device

■CNG post-dewatering device refers to the product with the pressure of the raw material gas up to 25MPa after the equipment is installed in the compressor. The utility model adopts the principle of temperature-temperature adsorption dehydration, utilizes the physical property of the adsorbent to adsorb the saturated water in the raw material natural gas under high pressure, and then uses the lower pressure dry gas to analyze the saturated adsorbent at a higher temperature. Adsorption and resolution are performed in reverse.

■The main valve of the process adopts the imported needle valve, the pressure port is set at the exhaust port, and the gas balance pipeline system is set at the time of regeneration switching to make the airflow run smoothly and protect the service life of the adsorber at multiple angles.

■The filter draining adopts double drain valve to ensure reliable discharge without leakage.

■ Adopt anti-ice plug pressure regulation design to make the regeneration gas flow more smoothly.

■Using a high-pressure external electric heater to make the regenerated bed layer evenly heated and easy to maintain and repair. At the same time, multi-point temperature monitoring can prevent dry burning and ensure the regeneration effect.

■Using self-cooling heat exchange, using the regenerative tower hot air to preheat the regenerative cold air after depressurization, to achieve the purpose of cooling the regenerative hot gas and solving the ice block problem after depressurization, and increasing the temperature of the regeneration gas entering the electric heater, Energy saving.
