Description
Technical field
The present invention relates to the residual neat recovering system in a kind of grain and oil expressing process, be mainly used in bean cake and steam de-and squeeze work in advance
Waste heat recovery in Duan, to reduce the steam energy consumption in this technique, reduces normal hexane and the discharge of dust, reduces CO2 discharge
Energy-conserving and environment-protective system.
Background technology
During the grain and oil processing of China, need to use substantial amounts of steam to add hot-air in Semen sojae atricolor squeezing process, pass through
The purging of hot-air makes bean cake be dehydrated, outside its direct drain chamber of used heat air.In the pre-squeezing and bean cake Zheng Tuo workshop section of Semen sojae atricolor
There is similar situation.
This type of process system also exists following deficiency:
(1) production cost
In Semen sojae atricolor expressing process, wherein having an operation is that bean cake steaming is de-.Height needs according to Semen sojae atricolor institute water content
The hot blast of 80---120 degree different temperatures goes purging to steam dehydration part, also holds the 80 of miscellaneous dust under the arm with a large amount of moisture content and a small amount of solvent
Waste gas about degree has been directly discharged into air.
In the production cost of oil pressing mill, the energy consumption cost of steam just account for 45%, and squeezing Semen sojae atricolor per ton needs 14.7kg to steam
Vapour.
(2) environmental problem
1., in whole production process, the most constantly there is the waste gas with 60---80 degree left and right temperature to enter in air,
Add the heat of natural environment, form hot dirt；
2., also with substantial amounts of water vapour and a small amount of solvent in waste gas, surrounding is caused dirt；
3. the waste gas after evapo-separated machine makes bean cake dehydration, removes bean cake dust despite by cyclone separator, but
Also have a small amount of dust to be carried under one's arms and give off system in the offgas.
So the discharge of this waste gas, dirt is caused for environment about so that the new wind that system is sucked has dirt,
Its production system and equipment are adversely affected.
(3) plant issue
Gas discharges the dirt caused to surrounding so that the suction new wind relative humidity of system fan is relatively big, also with
The normal hexane of trace and dust.
Dust can be bonded on steam heater, and the time one, long meeting formed dirt on tube wall so that heat transfer coefficient declines,
Heater heat exchange efficiency declines, and increases the usage amount of steam, finally increases production cost；So in actual use, people is run
Member's meeting water removes flushing heat exchanging device, not only wastes water resource and also can accelerate the corrosion of heat exchanger, shortens the use longevity of heat exchanger
Life, too increases production cost.
The normal hexane being in gas-liquid two-phase can produce corrosion to equipment.When the solvent liquid containing trace in the new wind sucked
Dripping, be heated through heater and be gasificated into gas, its corrosivity of normal hexane now is maximum, so heating the steam of carbon steel
Device causes certain corrosion, also will shorten its service life.
Causing steam to leak if steam heater is corroded, operator find the most in time, and steam will enter
Air side thus the humidity of air can be increased, bean cake is dried formation disadvantageous factor.
