Liquid Ammonia Regenerative Desiccant Dryers / Adsorbing Desiccant Dryers

Liquid ammonia adsorbing dryer device

Liquid ammonia dryer working principle :

This ammonia dryer adopt absorbing technology.The raw material come form Liquid ammonia storage

system,enter into dryer,will be adsorbed by 3A molecular sieves inside dryers,therefore to get pure

&clean ammonia dew point lower than -40℃.Because the molecular sieves will saturation after period of

time,so we molecular sieves must regenerate,while regeneration the molecular sieves temperature

should beyond 250℃,meanwhile inlet some nitrogen,which make molecular sieves moisture will be take

away by regenerate gas,regenerate molecular sieves can recycling using after cooling.Purification

package adsorbing dryer insist of two adsorbers,pneumatic valve,solenoid valve,two adsorbers fully

automatic control&switch,while one working another standby.

Dryers temperature control part make up of thermocouple,temperature

controller,contractor etc.Each adsorber will have one thermocouple,it located in the vessel middle position.

Adsorber 2 thermcouple will share one temperature controller,via auxiliary relay to switch,dryer only heating

control temperature when regenerate,the equipment heating temperature can set in temperature controller.

In order to prevent liquid ammonia freeze in winter Spaying device

Should be using in former,hot water provide by hot water gasification system,heater make water hot,spraying

ammonia cylinder,spaying water enter into water pool,via pump pressurize recycling heating,spaying.

This device regenerate gas-Nitrogen

Application:

Used in fields such as metal heating treatment, powder metallurgy, magnetic material,copper process,

metallic mesh, galvanized wire, semiconductor, etc.

2. Chemical and new material industries: For chemical material gas, pipeline blowing, gas replacement,

gas protection, product transport, etc. Used in fields such as chemical ,urethane elastic fiber, rubber,

plastic, tyre, polyurethane, biological technology, intermediate, etc.

3.Electronic industry: For encapsulation, agglomeration, anneal, deoxygenation, storage of electronic

products. Used in fields such as peak welding, circumfluence welding, crystal, piezoelectricity, electronic

porcelain, electronic copper tape, battery, electronic alloy material, etc.
