Description
Technical field:
The utility model relates to raw coal physical desulfurization technical field, relate to again middle low power microwave source combination technique field, relate to again the negative pressure of vacuum technical field of drying, relate to again and adopt the combined microwave device to carry out low temperature drying technical field in conjunction with vacuum negative pressure device, particularly the full sulphur fast processing of a kind of continuous processing type raw coal generates the device of Filter Tuber For Clean Coal.
Background technology:
Coal is one of fossil oil the abundantest on the earth, and in the total reserves of world energy sources, coal accounts for 2/3rds.With regard to China's energy structure, so far still take fire coal as main, this topsoil that has just determined China is for typically with discharging SO
2With flue dust be the coal-smoke pollution of feature.In coal, the existence of sulphur also can affect the quality product after Coal dressing.Therefore, more and more stricter for total sulphur content requirement in the coal of processing and utilization along with the enhancing of people's environmental protection consciousness, China has classified coal desulfurization as the clean coal technology research project of (CleanCoalTechnology is called for short CCT).So the coal desulfurization problem is an important research topic, solves it and is of great immediate significance.
Coal desulfurization and the sulphur occurrence status in coal has close relationship.In coal, sulphur can be divided into organosulfur and inorganic sulfur according to the occurrence status of sulphur.Organosulfur comprises mercaptan, thioether, thiophene phenol sulphur and disulphide, accounts for the 60-70% of total sulphur content; Inorganic sulfur comprises pyritic sulphur, sulfate sulfur and elemental sulfur, accounts for the 30-40% of total sulphur content, does not decompose during the inorganic sulphide burning, remains in ashes more.
According to the desulfurization process difference in stage of living in the coal utilization process, the coal desulfurization can be divided into desulfurization and the rear desulfurization of burning in the front desulfurization of burning, burning.Before coal burning, desulfurization is just to slough sulphur content in coal before coal burning, and in avoiding burning, the form of sulphur changes, and reduces the content of sulfureous in flue gas, alleviates the corrosion to back-end ductwork, reduces operation and maintenance cost.Before burning, desulfurization has many potential advantages than another two kinds of sulfur removal technologies, and meets the policy of " putting prevention first ", so before burning, desulfurization is significant.
Before the burning of coal, desulfurization can be divided into physical desulfurization method, chemical desulfurization method and biological desulphurization method etc.The complete processing of chemical desulfurization method and biological desulphurization method is more complicated, the treatment time is long, equipment and process cost is high, the waste after processing can cause secondary pollution to environment.The physical desulfurization method utilizes coal with pyritous nature difference (as surface properties, density, electricity and magnetic etc.), they to be separated, and comprises the methods such as gravity treatment, flotation, magnetic separation, oil aggregation.The method technique is simpler, and less investment can remove the pyrite of 50% left and right, and the pyrite effect that the coal camber is disperseed is little, and can not remove the organosulfur in coal.
Adopt microwave exposure to add character or the structure that hot coal decomposes or change inorganic sulfur in coal, and then the method for being removed in subsequent handling also can range the physical desulfurization method.The microwave desulfurization method is found to be the patent of the microwave desulfurization that Zavitsanos in 1979 and B leiler obtain the earliest.This patent points out, when raw coal at frequency 2145GHz, power 500W or higher microwave exposure 40s～60s, the inorganic sulfur in coal decomposes, and discharges H
2S and SO
2Gas, at coal Surface Creation elemental sulfur, the method can remove 50% sulphur.After this, the researchist adopts Mossbauer spectroscopy to analyze the variation of pyritic sulphur form after microwave irradiation in the raw coal, finds the intrinsic FeS in coal under microwave irradiation
2Converted the stronger pyrrhotite (Fe of paramagnetism to
1-xS) and two kinds of forms of troilite (FeS), can be rejected in magnetic separation after this.But as mentioned above, only add hot coal with microwave exposure, the inorganic sulfur in coal discharges H after decomposing
2S and SO
2Gas, and at the elemental sulfur of coal Surface Creation, be gathered in coal surface, hindered the effusion of the sulfur-bearing composition that decomposes thereafter, affected the effect that microwave exposure is processed.And, only add hot coal with microwave exposure, not obvious to the removal effect of organic sulfur in coal.
Therefore need physical method and the equipment of seeking a kind of non-secondary pollution, fast eliminating full content of Sulphur in coal that working cost is low badly.
Experiment showed, organosulfur contained in coal, comprise mercaptan, thioether, thiophene phenol sulphur etc., its boiling point is all relevant with ambient pressure.When ambient pressure reduces, the needed energy of these objectionable impurities boilings also can be reduced, so its boiling point also can descend thereupon.Usually, when pressure decreased arrived 2.67kPa (20mmHg), the boiling point of most organic compound was than low 100 ℃ of left and right of boiling point of its normal pressure.That is to say, under suitable negative pressure, for the above-mentioned organosulfur of boiling point higher than 100 ℃, as pentan-thiol (127 ℃), ethylene dithiol ether (154 ℃) etc., all can be removed at lower than the temperature of 100 ℃.
The variation of boiling point can be calculated by Clausius-Clapeyron equation integration type:
In formula: P1 is normal pressure, 0.101MPa; P2 is setting pressure; T1 is boiling point under normal pressure; T2 is the boiling point under setting pressure; Δ H is the evaporation enthalpy of the required objectionable impurities that removes, and its evaporation enthalpy varies with temperature not quite in actual process, therefore can think definite value; R=8.3144J/Kmol, universal gas constant.
The utility model is intended adopting negative pressure of vacuum in conjunction with the method for microwave heating, the full sulphur in coal to be carried out low-temperature negative-pressure and is processed, fast eliminating transpirable objectionable impurities wherein; And the inorganic sulfur in coal decomposes the H that discharges
2S, SO
2, and elemental sulfur steam, also taken away rapidly coal surface under the suction function of negative pressure of vacuum, strengthened the effect that microwave exposure is processed; Simultaneously, the pyrite under microwave exposure in coal is converted into rapidly the stronger pyrrhotite of paramagnetism and troilite, is beneficial in magnetic separation afterwards its rejecting; In addition, the treatment process that adopts the low temperature bond negative pressure below 100 ℃ on structure, cohesiveness and the calorific value of raw coal without impact.

Described treatment temp K can require to decide according to the complete processing of pending article, and as for coal, in order not affect its cohesiveness, calorific value, K is usually less than 100 ℃; For textiless such as clothes, carpets, K is 50～90 ℃ of left and right; Silk, K are 40～70 ℃ of left and right etc.
The boiling point of the material that described processing air pressure P can remove as required and evaporation enthalpy, treatment temp K are calculated by aforementioned Clausius-Clapeyron equation integration type.Table 1 has been listed the boiling point of some materials under normal pressure and evaporation enthalpy (as previously mentioned, the evaporation enthalpy of material varies with temperature not quite in actual process, therefore can think definite value).
The boiling point of table 1, some materials and evaporation enthalpy
See also Fig. 6, when the evaporation enthalpy of the material that removes when needs is unknown, just can not adopt Clausius-Clapeyron equation integration type to calculate, at this moment can utilize the air pressure of Fig. 6-boiling point empirical curve to try to achieve corresponding processing air pressure P by treatment temp K, or estimate the boiling point of this material under air pressure P by given processing air pressure P.Need in raw coal to suppose the material mid-boiling point that removes the highest be pentan-thiol, its boiling point is 127 ℃ as shown in Table 1.Suppose treatment temp K=70 ℃, at 70 ℃ that connect with straight line on Fig. 6 on 127 ℃ on the atmospheric boiling point curve and the boiling point curve that reduces pressure, and this straight line extended to pressure curve intersect at 115mmHg (15.3KPa), namely process pressure P necessary≤115mmHg (15.3KPa).
In this treatment temp with process under pressure conditions, in raw coal all boiling point all will be by fast eliminating together lower than the organosulfur of 127 ℃ under condition of normal pressure.
