Embodiment
Below, based on accompanying drawing preferred forms of the present invention is described in detail.
In Fig. 1, raw material (waste edible oil) is put into delivery cylinder 11 by tank wagon with accepting nozzle 10, filter screen 13, remove solid matter by accepting pipeline 12 from this delivery cylinder 11 (perhaps direct), put into receiving tank 16 more than 2 from discharging lateral line 15a by accepting pump 14 from tank wagon.
The quality of putting into the waste edible oil of receiving tank 16 is various, the waste edible oil of quality and difference thereof is difficult to take place transesterification reaction described later, so storage fine waste edible oil in any one of receiving tank 16, return by filter screen 13, receiving tank 14 from return pipeline 15b respectively, be supplied to raw material supply jar 17 from discharging lateral line 15a, thereby make stay-in-grade waste edible oil.The treatment capacity that this raw material supply jar 17 can be grasped every day probably is the capacity of 800L.
After being filtered by duplex filter 18,19 happy for example 34H/h send into the 1st in-line mixing tank 20 by the weight feed pump from the raw material of raw material supply jar 17.
On the other hand, catalyzer 23 such as alcohol such as methyl alcohol 22, caustic soda are supplied in the transesterify agent jar 21, stir, obtain the transesterify agent with stirrer 24.This transesterify agent makes it through quantitative (6.8L/H) filter screen pump 25 with respect to the caustic soda of the methyl alcohol interpolation 0.05kg of 1L, sends into the 1st in-line mixing tank 20.
Raw material and transesterify agent mix between flow periods in the 1st in-line mixing tank 20, and transesterification reaction takes place.The 1st in-line mixing tank 20 is accommodated in the cabinet C as described later, and the environmental gas temperature remains on 40～60 ℃, mixing raw material and transesterify agent in the 1st in-line mixing tank 20, thus can produce the successive transesterification reaction.
Fluid after the transesterification reaction switched and flow among the 1st glycerine separator tank 27a and the 2nd glycerine separator tank 27b by the switching of the 1st tripartite magnetic valve 26 in per 30 minutes in turn.
After accepting, in glycerine separator tank 27a, 27b, settlement separate successively, in glycerine separator tank 27a, 27b, monitor the interface of the glycerine of the thick recovered oil on top and bottom by optical profile type liquid level meter 28a, 28b, extract the settlement separate glycerine that is stored in the bottom out, send into glycerine storage tanks 30 by switching valve 29a, 29b.
Afterwards, close switching valve 29a, 29b,, will take in tundish 32 by the thick recovered oil that the ester that is kept at top constitutes by switching valve 31a, 31b.By repeating above action successively, can handle continuously.
As described later, the glycerine that stores in the glycerine holding tank 30 is supplied to boiler 70 by dual filter screen 71, pump 72.
Thick recovered oil is sent into the 3rd in-line mixing tank 35 through filter screen 33, pump 34 once more.
In neutralization washing water pot 40, mix clear water 41, dilute hydrochloric acid 42 and magnesium 43 by stirrer 44, in obtaining and washing water.Should in and washing water obtain with respect to 1L clear water mixing 0.02L dilute hydrochloric acid and 0.25kg magnesium.
By filter screen 45, weight feed pump 46 should in and after washing water are supplied to the 3rd in-line mixing tank 35 and thick recovered oil and mix with 35mL/H, by the 2nd tripartite switching valve 36, successively in a pair of and washing water separator tank 37a, 37b switch and transmit.Therefore, utilize and separate identical operations with glycerine, promptly in separator tank 37a, 37b by optical profile type liquid level meter 38a, 38b monitoring interface, by switching valve 39a, 39b, allow moisture settlement separate and that be kept at the bottom turn back to the neutralization washing water pot 40 by run by gravity from pipeline 35, be supplied to the vaporizer 61 of band outer cover described later by open and close valve 81 from pipeline 82 by run by gravity through open and close valve 80.
The vaporizer 61 of neutralization washing water pot 40 and band outer cover in cabinet C, be arranged on than in and washing water separator tank 37a, position that 37b is low, by separator tank 37a, 37b isolating in and washing water flow into the vaporizer 61 of neutralization washing water pot 40 or band outer cover respectively by run by gravity from pipeline 53,82.
Observe the concentration of corrective, when concentration is low, open open and close valve 80, in this and washing water return to the neutralization washing water pot 40 from pipeline 53, when concentration is high, open open and close valve 81, with in and washing water be supplied to the vaporizer 61 of band outer cover from pipeline 82.
Afterwards, close switching valve 39a, 39b, allow the thick recovered oil that is stored in top flow into regeneration oil tank 48 by switching valve 47a, 47b.
Recovered oil is supplied to the 3rd line mixer 52 from regeneration oil tank 48 by dual filter screen 50, pump 51, by pump 56 clear water is supplied to this line mixer 52 from the clear water jar 55 that stores clear water 54, mix continuously by the 3rd line mixer 52, by the 3rd tripartite switching valve 56, switch to and send into a pair of oil-water separation tank 57a, 57b successively.
In oil-water separation tank 57a, 57b, separate moisture equally, use optical profile type liquid level meter 58a, 58b monitoring interface therein, by switching valve 59a, 59b, allow moisture settlement separate and that be kept at the bottom be supplied to the vaporizer 61 of band cabinet from pipeline 60.
Afterwards, close switching valve 59a, 59b, the recovered oil that will be retained in top by switching valve 63a, 63b is supplied to steam heater 66.
To be supplied in the steam heater 66 by the steam that boiler 70 produces, recovered oil is heated to 100 ℃ of the moons at interval by this steam.Afterwards, recovered oil is supplied to separator 74, the steam in the separation regeneration oil makes moisture concentration in set(ting)value, is stored in the product jar 76 as the finished product.
In boiler 70, as mentioned above, glycerine is delivered to burning in the burner 73, be used to produce the saturated steam of 1.1kg/cm2h.
To and supply to from the washing water of pipeline 82 in the vaporizer 61 of band outer cover by the isolating waste water of oil-water separation tank 57a, 57b, to supply to from the steam of steam heater 66 in the outer cover of this vaporizer 61, waste water is by vaporizer 61 heating with outer cover, steam is discharged by pipeline 75, the waste water that reduces is discharged to outside the device after being discharged by waste water pump 77.
And, be kept in the water pot 78 from the water of condensation of outer cover, supply in the boiler 70 by condensation pump 79 circulations.
As mentioned above, cabinet C surrounds boiler 70, except that delivery cylinder 11, receiving tank 16, raw material supply jar 17, weight feed pump 19, basically armamentarium all is accommodated in this cabinet C, because remain in the cabinet C in 40～60 ℃ the environmental gas, so in transesterification reaction, need not heating raw, perhaps heat the 1st in-line mixing tank 20 in addition.And because the 2nd, the 3rd in-line mixing tank 35,52, tripping device 27,37,57 also remain in 40～60 ℃ the scope, so carry out good mixing and separate.
