Bell Type Furnace Cracking Ammonia Recovery Unit Energy Saving 200 Nm3/h

Bell Type Furnace Cracking Ammonia Recovery Unit Energy Saving 200 Nm3/h

Description:

Recovering hydrogen for recycling working.

Principle:

Domstic cold rolling steel annealing technical process as following chart,put steel strip into furnace,N2

purge heating cover,then add external cover inject pure hydrogen protective gas (then heating,inject

protective gas each period as heating period,keep warming period,cooling period,each manufactuer

technics different,the flow rate inject might have difference, before furnace finished inject nitrogen as

protective

In the first period of annealing,steel surface emulsion oil with heating volatilization,with temperature

raising,the oil without complied with heating gas will reacting.

At the begining,with temperature raising,steel surface emulsion water start volatilizate(about 100℃),

steel surface emulsion start reacting(about 300℃)

CnHm+O2 — CO+H2O

Hydrocarbon firstly reacte with O2 of Vapour,steel strip with mutually will become

CO,with tem improving,it will crack,atomic group smaller hydrogen molecule will

easily expanding with steel strip,all these atomic

group cracking place hydrogen is saturation,easily

become volatilization light hydrocarbon(450℃,while

H2 helpful for restore carbon,however there still

some carbon which inside steel surface,while 700℃

H2 will reacte directly with carbon,reacte CH4

CnHm+O2 — CnOm-2+H2

Steel annealing former process will use rolling oil,rolling oil main part is mineral oil,its main part including

each hydrocarbon-called impurities,mineral oil including sulphur,N2,O2 etc element

Recovering principle:

Bell type furnace system produce waste gas via former treatment unit(dry or water spraying)remove

waste gas dust,oil etc impurities,then waste gas via gas,water separator remove water&some oil, enter

into blower,the gas after supercharged will into deaerator remove O2,water will be produced&release

plenty of heat, after treatment gas via cooler discharge water&cooling,separate water via gas,water

separator,while oil filter remove oil,via adsorbing dryer to deeply remove oil,water,CO2 etc micro

impurities,finished waste gas purificaiton process; after that via pressure adjust device send to

furnace .
