Embodiment
As shown in Figure 1, water distilling apparatus of the present invention comprises retort 19 and is used for the body of heater 20 of heating.Retort 19 is to make of 304 stainless steels, and material thickness is thin, heat transfer is fast, indeformable, and easy burn-out not need not to change retort in 8-10, greatly reduces production cost and maintenance cost; The furnace wall material of body of heater 20 from inside to outside the first layer is alumina silicate block; use temperature is at 1600 ℃; the second layer is 20-30mm ceramic fiber cotton blanket; then use temperature is that the 50mm composite magnesium silicate is two-layer at 1600 ℃, and composite magnesium silicate is the expansion type material; in have a lot of fine close-connected poroid; heat insulation effect is excellent, and the provide protection to lagging material is played with the steel plate sealing of 1mm in the outside.The employing infrared thermometer is measured, and the steel plate hull-skin temperature is no more than 40 ℃.The present invention by three kinds of materials combination so that the furnace wall hull-skin temperature about 40 ℃.In construction process, alumina silicate block must water be dipped into the water surface comprehensively and emerge bubble for this reason, uses high-temperature agglomerant bonding again, makes whole edge joint performance good, does not smolder, and does not cause secondary pollution.
The oil gas that distills is by water cooler 28, water cooler 28 comprises cooling tank body 25,26,27, recirculated cooling water and horizontally disposed cooling tube are set in it, flow through in the cooling tube of oil gas in the uppermost cooling tank body 25 and be cooled, then enter successively cooling tank body 26,27 coolings, usually the flow direction and the oil gas opposite direction of water coolant are conducive to improve heat exchange efficiency like this.Oil gas is cooled to liquid rear to 30 minutes water of water trap, enters decoloration device 40 behind minute water again, the impurity such as the adsorption treatment function removal acid of utilization decolouring silica gel, alkali.Oil after the decolouring enters and stores fuel tank 50, and when oil arrived specified location, oil pump automatically startup pumped into fluid in the oil tank 60; This oil is base oil.The user is being deployed into needed oil product as required, after decolouring silica gel lost efficacy, the silica gel that will decolour is emitted and is carried out manipulation of regeneration, the decoloration device 40 of packing into again after the processing uses, the rate of recovery of each decolouring silica regeneration is between 95-98%, greatly reduce like this use cost of decolouring silica gel, also can not cause for the second time and pollute.The smog that whole equipment operation and silica regeneration produce, we carry naturally cooling to utilize activated carbon adsorption to process by off gas treatment tank 70 by pipeline, after process water treatment tank 80 is crossed water treatment again, are discharged by vacuum fan, the expellant gas colorless and odorless, zero disposal of pollutants.Whole system has all embodied the value of recycling, and making product really reach environmental protection is target, satisfies various users' requirement.
Further, the water distilling apparatus system adopts hermetically sealed, and the gas of distillation can not leak gas; reliable securing system is arranged; the over-temp and over-pressure automatic control alarm system is arranged, over-temp and over-pressure automatic interlock Controlling System is arranged, Controlling System comprises that automatically unloading, mechanical release two portions form.Can automatically control, also can manually operate, ensure safety.
In the production, must confirm moisture content in the waste oil before the retort 19 interior pump oil by oil reservoir 12, moisture content can not surpass 3-5%, excess moisture can be wasted fuel, increases the treatment time, increases the required water yield of water-cooling system, cooling performance is poor, increase the difficulty that oil product divides water, decolouring, affect color and the quality of oil regeneration, also increase the discharge capacity of waste gas simultaneously.When the startup scavenge oil pump pumps into waste oil in the retort, can not add waste oil too much, addition generally be not more than the 50%-70% of the useful volume of retort.Purpose is to add waste oil too much: the oil mass that can only add exactly is volume a greater part of of retort; Prevent fluid boiling effusion, affect follow-up minute water; Simultaneously prevent that also impurity from entering into subsequent handling with liquid oil.Behind the complete waste oil of pump, closeall fuel inlet ball check valve.Start scavenge oil pump after 10 minutes, start the burner heating, start vacuum fan, off gas treatment water pump, cooling-water pump, check whether all energising equipment operation situations are normal.
In refining process, in the time of need to quitting work, first brennschluss burner after temperature drops to below 200 ℃, can stop to provide cooling-water pump, off gas treatment water pump, the vacuum fan of water coolant temporarily.
In refining process, when oil temperature reaches 300 ℃ the firepower of burner reduced, make the oil temperature lift velocity slack-off, continue for some time like this, for example one to three hour, if oil temperature surpasses 360 ℃ then the heating of cease combustion device, make between oil temperature slowly falls back to about 320 ℃, make basically all evaporations of oil; And then continue with being heated to about 600 ℃, when the temperature fast rise and when reporting to the police, close combustion engine, other device requirements continue to run until can all operations of arrestment when drop in temperature puts 150 ℃ of left and right sides in place.Namely slow rear fast first, the middle roughly still-process of constant temperature is with the whole evaporations of the oil in the retort 19.Do not cause simultaneously the pyrometamorphism of oil, needing at last suitable short time high temperature then is in order to promote the coking of waste material, to be convenient to cleaning and not cause environmental pollution.
In oil refining process, must guarantee that the coolant water temperature of cooling water tank 90 can not be above 50 ℃, otherwise bad to the oil gas cooling performance, oil gas directly arrives fuel reserve tank by decoloration device 40, and discharge by venting hole, can cause fluid residence time in decoloration device 40 too short, affect the oil product decolorizing effect, also cause oil gas not cool off and cause the waste and environmental pollution.
In conjunction with shown in Figure 2, the present invention is provided with silica gel regenerator 10, and the decolouring silica gel after using is carried out activating and regenerating.For making those skilled in the art more properly understand technology contents of the present invention and effect, with internal diameter 0.6m, the height 1.35m of body of heater 10, single treatment amount 0.5m
3The regeneration body of heater be example, introduce the concrete operations explanation of silica regeneration:
Open the lower end cover 17 of bottom, check and adjust the conical baffled 14 of the inside, make it be in the position that overlaps with body of heater 10 axle cores, namely keep off the mid-way in inside, body of heater 10 lower end.
Open loam cake 1, the plectane 11 in the body of heater 10 is taken out.
Decolouring silica gel after filling is used fills first particle diameter usually at the thick silica gel of 4～8mm, refills particle diameter at the thin silica gel of 0.25～2mm; Simultaneously preferably top is that thinner Kiselgel A, the bottom of micropore size on the silica gel particle is silochrom, guarantees that oil content circulation downwards is comparatively unobstructed, thus simultaneously Kiselgel A because separate the oil content difficulty greatly from thermal source close to, guarantee regeneration effect.Because itself have a lot of microvoid structures on the silica gel, so also can transmit and realize regeneration even only fill the Kiselgel A heat, just need the heat-up time of regeneration to prolong.Silica gel installs to the top side and is advisable from the about 50MM of orifice plate that places plectane 11, avoids silica gel directly to contact with flame, after installing, plectane 11 is put back to build, and closes loam cake 1.
Build lower end cover 17, upper two or three bolts just with good all right on hand, should not be gone up too tightly, in order to unscrew.
With the inflammable substance such as refuse that oil is arranged fire is ignited first during igniting, add firewood, start simultaneously blower fan 4.Firewood just burns at the plate body of plectane 11 and side, and through hole downwards logical flame and hot gas are set on this plate body and the plectane 11.Firewood once should not add too much, avoids causing a fog in body of heater 10 and burning insufficient.
After burning about 30 minutes, slowly loosening the bolt of lower end cover 17, until lower end cover 17 places still have the slit but not smoke, the oil content outflow is convenient in such slit.
Have soon oil this moment and flow out from lower end cover 17 edges, connect with container, continue heating until lower end cover 17 edges are not fuel-displaced.During lower end cover 17 places are fuel-displaced, there is smog out, then bolt is tightly suitably tightened, but can not tension, flow out in order to avoid affect fluid.
In combustion processes, note adding firewood, observed every 10～15 minutes; Midway can not cease combustion heating, the smog that 17 places are covered in about 1 hour posterior end reduces and becomes that explanation smog mainly is water vapour behind the white colour, does not almost have oil gas; Just can blowing-out machine 4, certainly, proper extension also is fine heat-up time, usually treats body of heater 10 interior firewood after-flames.
After the shutdown, if at that time need not, need to all bolts on the lower end cover 17 be tightened, remaining opening also will seal, and keeps body of heater 10 inner chambers not enter air, avoids silica gel to make moist, and affects decolorizing effect.
Perhaps until opening lower end cover 17 after the silica gel cooling silica gel after regenerating is emitted from the bottom.If directly discharging or treat that temperature suitably is higher than the room temperature discharging then will by instrument, avoid scalding.
Silica gel after the regeneration does not have considerable change with the main performance index of using front product (the new silica gel product when namely not using), meets service requirements, and concrete testing data is as shown in table 1:
Table 1:ZCX-I column layer chromatography silicone rubber product uses the main performance index after front and the regeneration
During technical finesse silica gel of the present invention, in the firewood combustion process, oil, acidity, greasy filth, moisture contained in the silica gel decomposes, volatilizees and discharge with smog, thereby reaches the purpose that silica gel reclaims.Can carry out activating and regenerating with existing silica gel with the kin product of silica gel, significantly reduce the product use cost.Have significant economic benefit and environmental benefit.Add thermogenetic ash content as for firewood and be blended in the silica gel then not obviously impact of performance on silica gel, because ash content is mainly the salt of alkaline matter or inertia, and in the oil product decolouring removal process filtration unit is arranged in decolouring, so can not impact oil product and recovery and use.
