Electron filed 100Nm3/hr 110 PSIG ammonia dryer with fully
automatic control system HMI for Multi-purpose furnace
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

gas-adjusting package and nitrogen package of fruits, vegetables,
flowers, tea leaves and puffed food, custard pie, milk bread,
European-style egg roll, various cookies, farm products and local
special products, such as rice, seed and chestnut, also kinds of
drugs etc .
5. Metallurgy: For anneal protection, agglomeration protection,
nitrogenizing, furnace washing and blowing, etc. Used in fields
such as metal heating treatment,powder metallurgy, magnetic
