Concise and to the point description of drawings:
Accompanying drawing 1 is one embodiment of the present invention synoptic diagram,
Accompanying drawing 2 is the another embodiment of the invention synoptic diagram,
Accompanying drawing 3 is the used pulse combustor exemplary construction of the present invention constructed profile.
Best mode for carrying out the invention
At first be the pre-treatment work of dung urine.Tank is dropped in the receiving tank with transporting the dung urine that comes, and this material sieves (scalping) through a dung slag, secondary dung slag sieve (dusting cover) isolate the dung slag, the dung urine by sieve is stored in the conservation tank.Through once, the dung urine that sieves of secondary, sieve for the third time after pulverizing with dung slag macerator pump, making it by the mesh aperture is the sieve of 5mm, isolates the dung slag again, the permeate deposit is in the service jar.Below, we will illustrate implementation step of the present invention according to Fig. 1.The dung urine that stores in the service jar (not marking in the drawings) is sent into from the dung urine supplying opening 2 of right circular cylinder shape kiln 1 by dung urine supply pump (not marking in the drawings), burner 3 is equipped with at the kiln top, makes above-mentioned dung urine be the vaporific burning gas that sprays to pulse combustor discharge downwards in burning gas vapor pipe 35 exits and also contacts with it.Because the temperature of pulse-combustion gas, is treated to send in the kiln after temperature is reduced to 500 ℃～600 ℃ so preferably make it earlier to mix with secondary air more than 1000 ℃ again.Solids component in the dung urine has membrane structure mostly, so if adopt common warm air drying, it is very long that intracellular moisture all evaporates required time, but the impulse drying method is quite different, pulse-combustion gas frequency per second 50～700 (H
2), normally used pulse-combustion gas frequency is per second 100～150 (H
2), simultaneously with sound wave and pressure wave, sound wave, pressure wave can destroy cytolemma rapidly, make the cell instant dehydration become dried powder and water vapour at once.For preventing the water vapour dewing corrosion metal in the waste gas, the kiln temperature should be controlled at more than 100 ℃, considers that the dried powder firing point is 205 ℃, for the unlikely dried powder that causes catches fire, temperature should be lower than 205 ℃, so the optimum temps of kiln should be controlled at 120 ℃～150 ℃.When pulse-combustion gas and moisture 97% dung urine contact in moisture eliminator, the dehydration rapidly of dung urine, temperature transfers 120-150 ℃ in the moisture eliminator.The temperature of kiln can be by control fuel throwing amount, the secondary air amount of adding in the pulse-combustion gas; The feed speed of dung urine etc. is regulated.Heavy dried powder is deposited on the kiln bottom more; Collect with slusher 4, the worm conveyer 5 of bottom, drying chamber is discharged again.It is fibrous or microgranular that dried powder is, but non-adhesiveness is difficult for being attached to the kiln inwall, so available slusher is removed; Discharge from the kiln bottom then.Simultaneously by one-time dedusting device 6, after dust removal process, discharged by worm conveyer 5 by final dusting device 7 together with waste gas for the less dried powder of proportion.Burning gas after the dust removal process is extracted out by vacuum fan, makes it by odor removal 8, and deodorizing enters atmosphere after handling.The combustion exhaust that has water vapour is after leaving kiln, and its temperature maintains all the time carries out processing such as dedusting, deodorization more than the dew point.More than be that example is illustrated with dung urine, other also can do same processing as the mixture of purification tank mud and dung urine and purification tank mud etc.
Next is the treatment process about the dried powder of discharging through worm conveyer 5, and these powder are sent into the recovery funnel by Transport Machinery and reclaimed, and therefrom quantitatively are discharged into solidification equipment, quantitatively discharge in the form of sheets after the curing.With once, secondary, sieve for three times the dung slag that reclaims and granular cured article put into roasting kiln in the lump and burn.Solids component accounts for 3% of whole dung urine amounts.Once, the thermal value of secondary, the dung slag that sieves for three times is 6000kcal/kg, the thermal value of dried powder that slusher is collected or that reclaim through the one-time dedusting device is 4000kcal/kg, its true specific gravity is 1.55, bulk specific gravity is 0.08, the thermal value of final dusting dust that device reclaims is 2250kcal/kg, true specific gravity is 1.59, and bulk specific gravity is 0.22.
Be the explanation of relevant pulse-combustion gas below.The thermal pulse burning gas is produced by so-called pulse combustor, is that a kind of frequency is per second 500～700 (H
2) intermittent combustion gas.Send into the water-containing material of this burning gas scope and not only accept the warm air drying effect, but also be subjected to physical property impact (acoustic force and the pressure) effect that quick panting action produces, because water-containing material can be in the instant dehydration drying, this drying machine that carries out the water-containing material high-efficiency dehydration with the pulse combustor hot air source is gazed at very much.
The design of pulse combustor is based on the jet engine technology, wherein, the pulse combustor that can be used for dry water-containing material has multiple model, with number disclosed pulse combustor of special fair 6-339 shown in the accompanying drawing 3 is that representative illustrates, pulse combustor 3 has at least one air of equipment and sends into pipe 31, at least one fuel is sent into the combustion chamber 34 of pipe 32 and at least a portfire 33, with install in turn along axis A-A with it, the burning gas vapor pipe 35 that Diameter Gradual Change is thick, and the diameter of combustion chamber and vapor pipe 35 interfaces 36 has the shape facility of retraction.Portfire 33 adopts electric ignition plug (ignition plug), or pilot(light)burner (pilot flame) etc.Pulse combustor shown in accompanying drawing 1～accompanying drawing 3, at its external chuck 37 that is equipped with, after in sleeve pipe, being blown into secondary air, the burner body cooling simultaneously, secondary air also is able to preheating, like this, mix with near burning gas vapor pipe 35 pulse-combustion gas phases of discharging, reach and regulate the purpose that enters the pulse-combustion temperature degree in the moisture eliminator by the secondary air that makes preheating.The pulse-combustion gas that the present invention not only uses this gas-burning pulse producer to be produced, the pulse-combustion gas that gas-burning pulse producer is otherwise produced.
Be the starting explanation of relevant pulse combustor below, send into air by air input tube 31 to combustion chamber 34, oil fuel such as diesel oil are vaporific ejection by fuel inlet pipe 32, when combustion chamber 34 is full of air and fuel, electric ignition plug 33 igniting produce spark, explosive burning takes place, and burning produces hot gas and discharges through vapor pipe 35.Because instantaneous pressure in the combustion chamber 34 during burning, the supply of air and fuel is by temporary interruption, but after burning gas is discharged via vapor pipe 35, be low-pressure state in the combustion chamber 34, the supply of air and fuel recovers again, through changing hot gas into after igniting once more, the explosive burning, so go round and begin again then.Like this, intermittent explosive combustion has not only produced pulsation hot gas, has also produced sound wave.So the water-containing material of that pack into or 35 outlets of arrival vapor pipe also is subjected to the physical impact effect (sound wave and pressure wave) that quick pulsed gas produces except that accepting hot gas drying, moistening raw material can be by instant dehydration.The starting impulse burner is after for some time like this, and the inwall of combustion chamber 34 promptly is scorching hot state, even the air of input and fuel produce electrical spark without electric igniting, also can be by the igniting automatically that contacts with scorching hot inwall, and the burst that repeats to be interrupted burning.Its principle of work is the same with hob bulb engine.Under this state, the igniting of electric ignition plug stops, but combustion chamber works better still.
