Abstract
The invention discloses an edible oil tail gas absorber. The working principle of the edible oil tail gas absorber comprises the following steps: condensing all solvent gases from an extraction workshop in a condenser, introducing the condensed solvent gases into a water knockout drum, enabling the separated out water to flow into a cooking pot, steaming out the solvent retained in the water, discharging the wastewater in a water seal tank, introducing non-condensable gases (tail gases) into a paraffin absorbing device, introducing the gases from the bottom of the tail gas absorber, flowing lean oil from the upper part of the tower, making the lean oil pass through a filler layer at the upper part and be in countercurrent with the tail gases, emitting the absorbed tail gases through a back-fire relief valve, and resolving and recovering the rich oil absorbing the solvent in a desorption tower after heat exchange. The edible oil tail gas absorber can reach the purposes of reducing the solvent consumption and ensuring the safety production.
Description
Technical field:
The product the present invention relates to, is widely used in edible oil and fat engineering and leaches the recovery of operation solvent high-efficiency and environmental protection technical field.
Background technology:
At present, the grease processing enterprise edible fat leaching operation of domestic various scales; Dissolve the edible oil and fat in oil plant by solvent naphtha, then different from the boiling point of edible oil and fat and water according to solvent naphtha, separate by evaporation.Solvent naphtha separates can not be thorough, causes solvent consumption excessive; Bring unnecessary economic loss to enterprise.Simultaneously solvent consumption is many may be the reasons such as solvent does not reclaim thoroughly, after not having thorough recovered solvent gas to discharge to contact with naked light, brings the danger such as blast and environmental pollution.The product that this project is related, can reduce the problems referred to above and occur.
Summary of the invention:
The product that this project is related after condensation, enters water knockout drum according to leaching all solvent gas in workshop in condenser, the solvent separating overflows to solvent storehouse and recycles, the water separating flows to cooker, and residual solvent in water is steamed and taken off, and then waste water enters water seal tank.Infuser condenser, energy-saving appliance condenser, liquid collecting tank water knockout drum, circulating solvent tank free gas out all enter air balance tank, reclaim solvent through last condenser.On-condensible gas (tail gas) enters paraffin absorption plant, gas enters from bottom, absorption tower, oil-poorly flow down from tower top, the packing layer being provided with through top and the absorption of tail gas counter current contacting, the tail gas after absorption enters atmosphere by exhaust fan through spark arrester from top, absorption tower.The rich oil that has absorbed solvent enters desorber top after heat exchange, and upwards, the oil-poor absorption tower that enters after heat exchange after desorb recycles the live (open) steam adverse current spraying at the bottom of tower, and the gas of desorber discharge enters energy-saving appliance.Be all organic matter according to paraffin and solvent naphtha, institute has intermiscibility; Solvent gas will be contained, by paraffin lyosoption gas in tail gas in leaching system; Then resolved and separated recovered solvent oil by desorber, tail gas is discharged by spark arrester; Thereby reach the object that reduces molten consumption, guarantees safety in production.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described, and Fig. 1 is the related product structure schematic diagram of this project.
As shown in Figure 1, exhaust outlet 1, flash tank 2, wire packing 3, oil-feed spray equipment 4, two trumpeter holes 5, bearing 6, absorber portion 7, filler support 8, Pall ring filler 9, free gas import 10, the overflow mouth of pipe 11, surge tank 12, the liquid level gauge mouth of pipe 13, the emptying mouth of pipe 14, glass-tube liquid level meter 15, a trumpeter hole 16, straight barrel 17, adpting flange 18, No. two straight barrels 19 form.
The specific embodiment:
As shown in Figure 1, straight barrel is formed by connecting by adpting flange 19 by a straight barrel 17 and No. two straight barrels 19 the related product of this project.A straight barrel 17 and No. two straight barrel 19 inside are provided with filler support 8, and fill Pall ring filler 9; No. one straight barrel 17 lower ends are connected to surge tank 12, surge tank 12 is provided with free gas import 10, the overflow mouth of pipe 11, the liquid level gauge mouth of pipe 13, the emptying mouth of pipe 14, glass-tube liquid level meter 15, and glass-tube liquid level meter 15 is bolted two liquid level gauge mouths of pipe 13 that are provided with at surge tank 12; No. two straight barrels 19 are provided with oil-feed spray equipment 4,6, No. two straight barrel 19 upper ends of bearing are connected to flash tank 2; Flash tank 2 is provided with exhaust outlet 1, and flash tank 2 inside are provided with wire packing 3.Equipment is vertically fixed in system by bearing 6, when on-condensible gas (tail gas) enters surge tank 12 from free gas import 10; After cushioning even pressure, free gas upwards moves.Paraffin oil sprays downwards with vaporific form from oil-feed spray equipment 4; Conduct heat to the Pall ring filler 9 that is arranged on a straight barrel 17 and No. two straight barrel 19 inside through tail gas, make upwards to move on-condensible gas (tail gas) and slow down with the speed that operation paraffin oil moves in opposite directions downwards; Solvent gas and the indissoluble surge tank 12 that enters of paraffin oil in on-condensible gas (tail gas) simultaneously, the overflow mouth of pipe 11 being provided with by surge tank 12 is transported to Analytic Tower solvent gas is separated to rear recovery.The tail gas of lyosoption gas upwards moves exhaust outlet 1, the discharge of the spark arrester safety arranging on exhaust outlet 1; Thereby reach, solvent gas reclaims and tail gas safe discharges, the object of environmental protection.
