Description
Technical field
The utility model relates to biomass energy technology field, is specifically related to a kind of cooking range capable of gasifying.
Background technology
The target that lignocellulose-like biomass (hereinafter referred to as living beings) gasifies obtains fuel gas product as much as possible, but in existing biomass gasification process, tar is inevitable accessory substance seemingly.The present situation that the common gasifying range for biological substance smoke fire in market burns is more common, and wherein reason mainly lacks the separation of tar in biomass cracking gases and lacks the effective means promoting secondarily cracking tar.Because tar is gaseous state when high temperature, mix completely with fuel gas, and when low temperature (as lower than 200 DEG C) be condensed into liquid state, easy He Shui, ash grade and combine, blocking cracking gas passage, biomass gasification equipment is run difficulty occurs.In addition, the existence of tar also has other adverse effect to gasification, first that reduce gasification efficiency; Secondly the very high PAH(polycyclic aromatic hydrocarbons of content is contained in tar ingredients), PAH has carcinogenic danger and is difficult to administer, and can cause permanent pollution, be detrimental to health to environment, must reduce it as far as possible and occur.
There is the high or inefficient problem of tar processing of tar content in combustion gas in traditional gasification furnace major part.Chinese patent CN 1664066A discloses a kind of combined biomass vaporization furnace and pyrolysis installation, and its drip irrigation device is: be made up of two biomass gasifying furnaces and four cover U-shaped catalyst converters.Although the goudron lysis rate of this design is better, complex structure, cost compared with high, system is huge, equipment occupation space is large, is not suitable for rural households' use.
Dolomite studies at most so far and the most successful secondarily cracking tar catalyst, general as CaCO in dolomite
3/ MgCO
31 ~ 1.5 time, effect is better.Dolomite is that catalytic efficiency is high as the major advantage of tar cracking catalyst, low cost, so have good practical value.
The most important factor affecting dolomite catalytic tar lytic effect is temperature and time of contact.More than 800 DEG C, namely there is very high cleavage rate, and desirable effect can be obtained at about 900 DEG C, and the temperature close of this temperature and gasification of biomass.Time of contact is determined, so the granular size of the gas phase time of staying and dolomite becomes the important process condition of catalytic pyrolysis by the specific area of the gas phase time of staying and catalyst.Such as at 800 DEG C, the gas phase time of staying, to the dolomite of d ≈ 2.00mm, its catalytic efficiency reached 95% when about 0.5s.
