Abstract
The utility model relates to a garbage gasifier, which works based on the principle of the fixed-bed pressure gasification and has solid carbon waste with instable thermoplastic plastic in gasification. A conical or cylindrical non-cooling loading shaft designed according to the design and made by heat-resistant materials is arranged below the gate at the lower part of the loading mouth of the utility model, and enters into the fixed-bed pressure gasifier for about 700 to 1200 mm. A crude gas discharge device is arranged beside the loading shaft and comprises a bevel pipe section or a bend and extends into the dome region of the fixed-bed pressure gasifier, and a T-shaped section is arranged on the gas inlet of the discharge device to minimize the temperature of the gas inlet.
Description
The present invention relates to by means of the fixed bed pressure gasification device environment advantageously be got rid of the field of rubbish, wherein the waste material of being inserted mainly is the solid waste materials containing carbon, and they have the unsettled thermoplastics of share.
Design of fixed bed pressure gasification device and production are used for producing coal gas by coal.Owing to this reason, whole members of fixed bed pressure gasification device are at the gas yield maximum is optimized.In the early 1990s, beginning is gasification solid waste materials containing carbon in this fixed bed pressure gasification device, especially also contains this waste material of thermoplastics composition.Should point out emphatically, by the known coal distribution apparatus of coal gasification on fixed bed pressure gasification device top, and be not suitable for the solid waste materials containing carbon, because the mixture that most of this waste materials are made up of the distinct material of reacting by heating, and the share of thermoplastics is exactly unstable and unpredictalbe from the beginning.
Similar by the known truncated cone shape roof about 50 ° of brown coal hydrogasification with having proved suitable high-power coal sparger and pitch angle there, on it, settle a hollow cylinder to the band side direction raw gas outlet of lower opening.Play the coal gas collecting chamber at the cavity of truncated cone shape undersurface of roof with the hollow cylinder of arrangement.This combination by coal sparger, coal gas collecting chamber and raw gas outlet, be located between the parts and producer inwall of fixed bed pressure gasification device center upper portion at these, form a circular clearance reluctantly, be used to the brown coal piece of importing and on coal piling, distributing and be transfused to.This frame mode has explanation in professional book, " Gaserzeugung und Gasaufbereitung " (editor: GaskombinatSchwarze Pumpe for example, Deutscher Verlag f ü r Grundstoffindustrie Leipzig1987,202 pages).Also can see the synoptic diagram of above-mentioned parts by DE4125518.
Mentioned coal sparger, collection and confinement of gases chamber and raw gas outlet combination have structurally proved suitable in the gasification of brown coal piece.For the waste material (great majority of the rubbish kind that is provided on the market are this situations) that contains the thermoplastics composition is provided, proved already that the frame mode of described coal sparger and raw gas outlet was inapplicable.When stating the solid carbon waste material that contains the thermoplastics composition in the use, the plastic state of thermoplastics composition, according to the temperature distribution in the fixed bed pressure gasification device, also just form at height place, the place of so-called coal sparger as far back as the top of fixed bed pressure gasification device.The part that becomes plasticity in the employed waste material is bonded on the truncated cone shape top cover of coal sparger, and thereby the aperture of the circular clearance of wanting of having reduced between coal sparger and producer inwall to overstate for the best filling of fixed bed pressure gasification device.Under extreme case, may cause entirely shutting of circular clearance.Require the fixed bed pressure gasification device out of service immediately when this thing happens.If adhesive do not have complete shutoff circular clearance, then worsened the filling of producer, its consequence is to reduce the quality of raw gas, increase dust output from the fixed bed pressure gasification device, cause the oxygen invasion and attack dangerous and increase the cleaning amount.
Therefore gasify known coal sparger for using carbonaceous solid refuse by the brown coal piece, this rubbish that especially contains the thermoplastics composition is inappropriate.
So the objective of the invention is to find a kind of technical scheme, can in traditional fixed bed pressure gasification equipment, import and gasification solid waste materials containing carbon by it with having no problem, especially contain this waste material of thermoplastics composition.
For reaching the measure that this purpose takes be, establish a cylindrical or conical charging pit shaft below the gate of charging bole bottom, it stretches in the fixed bed pressure gasification device about 700 to 1200mm.Its diameter depends on the frame mode of fixed bed pressure gasification device.This charging pit shaft is a refrigerative not, but makes with heat-stable material.
Temperature distribution in the fixed bed pressure gasification device makes and has existed below the pit shaft temperature at 575-700 ℃ so-called pyrolysis zone in charging.Must form a space in the side of above-mentioned charging pit shaft as collection and confinement of gases and stable cavity.In this collection and confinement of gases and stable cavity, stretch into one towering always to intraparietal bend pipe of fixed bed pressure gasification device circle or knuckle pipeline section.Bend pipe or knuckle pipeline section upwards can finish with a superincumbent T shape section of arrangement, and it is used to make gas velocity to minimize.
Show its feature by the solution of the present invention by following advantage:
-can cancel complicated assembly work basically.
-in the fixed bed pressure gasification device, reach uniform charging.
-whole stockpile surface can utilize as gas and discharge face, reduces gas velocity and dust output thus.
-by being reduced in the insecurity that oxygen level increases in the raw gas largely, because fixed bed pressure gasification device and output mechanism irrespectively tend to so-called road ability placed in the middle (Mittelg ngigkeit) at central authorities' input gasification materiel.
-because bigger space is arranged, guarantee the reliable pyrolysis of the waste material that contains the thermoplastics composition that is added above fuel assembly.
The layout of charging pit shaft of the present invention and raw gas discharger is pressed in-employing, high approximately 1.5-2m when gasification materiel stacking aspect ratio coal sparger is pressed original design.This just guarantees to provide more carbon in the fixed bed pressure gasification device, and meanwhile guaranteed the required space of mass loss that produces during in pyrolysis at the gasification materiel of importing under the situation of the high ratio of mixture of waste material can not increase the possibility that courts with thermoplastic properties.
Below can be by the present invention of embodiment brief description.
Attached Fig. 1 and 2 is respectively the longitudinal section with conical and columniform charging pit shaft refuse gasification device.
Be illustrated below in conjunction with embodiment by the structure of Fig. 2.
Below charging bole 5 bottom gates, establish a cylindrical charging pit shaft 1 in central authorities.This charging pit shaft stretches into about 1000mm in the fixed bed pressure gasification device.The bore of charging pit shaft 1 is 1450mm.Depend on operation scheme, the distance between charging pit shaft 1 lower end and the stockpile surface 4 is minimum to be 500mm.
