Description
Technical field
The utility model relates to the residual neat recovering system in a kind of grain and oil expressing process, be mainly used in dregs of beans and steam the waste heat recovery in Tuo Jiyuzha workshop section, to reduce the steam energy consumption in this technique, reduce the discharge of n-hexane and dust, reduce the energy-conserving and environment-protective system of CO2 discharge.
Background technology
In the process of the grain and oil processing of China, in soybean squeezing process, need to use a large amount of Steam Heating air, make dregs of beans dehydration by the purging of hot-air, outside the direct drain chamber of its used heat air.In the pre-squeezing of soybean and dregs of beans Zheng Tuo workshop section, there is similar situation.
In this type of process system, exist following deficiency:
(1) production cost
In soybean expressing process, wherein having an operation is that dregs of beans steaming is de-.Needing the hot blast of 80---120 degree different temperatures to go to purge according to the height of soybean institute water content steams the part of dewatering, has directly entered atmosphere with the waste gas that moisture content and a small amount of solvent are also held under the arm about 80 of assorted dust is spent in a large number.
In the production cost of oil pressing mill, the energy consumption cost of steam has just accounted for 45%, squeezes soybean per ton and needs 14.7kg steam.
(2) environmental problem
1. in whole production process, constantly have all the time with the waste gas of 60---80 degree left and right temperature and enter in atmosphere, increased the heat of natural environment, form hot dirt;
In waste gas also with a large amount of water vapours and a small amount of solvent, surrounding environment is caused to dirt;
3. the waste gas after evapo-separated machine makes dregs of beans dehydration, although be by cyclone separator, dregs of beans dust to be removed, also have a small amount of dust to be carried under one's arms and in waste gas, gives off system.
So the discharge of this waste gas, causes dirt for its environment around, makes the new wind that system sucks have dirt, and its production system and equipment are caused to adverse influence.
(3) plant issue
Gas discharges the dirt causing to surrounding environment, makes the new wind relative humidity of suction of system fan larger, also with micro-n-hexane and dust.
