Description
Technical field
The present invention relates to a kind of tar Pintsch process system, especially a kind of biomass coke tar Pintsch process system.
Background technology
The target of gasifying biomass is an acquisition inflammable gas as much as possible, but in gasification, coke and tar all are inevitable by products.Tar is gaseous state when high temperature, mix fully with inflammable gas, only when being lower than below 200 ℃, temperature just can be condensed into liquid state, so separation and processing are very difficult under vaporized state, need lower the temperature (when being used for family or oil engine generating as combustion gas) when utilizing when combustion gas, problem is more outstanding.
The existence of tar has many-sided disadvantageous effect for gasification, at first it has reduced gasification efficiency, the energy of coal-tar middle oil product of gasifying generally accounts for the 5%-15% of total energy, this part energy is difficult to be utilized with inflammable gas when low temperature, secondly tar is condensed into liquid state when low temperature, mix with water, coke, stop up air duct, influence equipment for gasification and normally move.Once more, the tar that is condensed into fine drop has hindered the perfect combustion of combustion gas, and particles such as the carbon black of generation utilize equipment (as: oil engine, internal combustion turbine etc.) infringement quite serious to combustion gas, and this just greatly reduces the utility value of gasification burning.In addition, cooled thickness attitude tar be difficult for to reclaim, most of gasification stations, and after the tar that produces in the vapourizing furnace gasification is discharged from, sinuous flow everywhere, unattended had both polluted environment, had wasted the energy that tar contained again.
Summary of the invention

Its working process is: collect tower by tar, the tough tar of cold conditions is concentrated reclaimed.Connect heater power source, the tar heating container is heated, by the tar charging opening, the tar that tar is collected in the tower is sent in the tar heating container, and tar is heated then, reduce its liquid viscosity coefficient, meanwhile, the tar whipping appts by tar heating container top constantly stirs the tar in the tar heating container, further reduce its liquid viscosity coefficient, strengthen mobile.According to experimental result, this technology stirs the rotating speed that adopts 250r/min, and the heating tank temperature is controlled between 110 ± 2 ℃, makes the tar diluted viscosity reach 500mm
2Below/the s, the tar under this state is fit to remote fluid and carries very much.In the tar of the easy contaminate environment of handling, effectively promoted the calorific value and the quality of combustion gas, according to the experiment test gained, fuel gases calorific value promotes nearly 20%.
Thermal insulation layer insulation by being installed in tar heating container outside and temperature shows and control device carries out temperature control, the temperature maintenance of guaranteeing the tar heating container is at design temperature, when tar is heated to certain hour, when having certain fluidity, by the tar pump, the mobile thermal tar is pumped from the tar heating container by insulating pipe, the tar discharge nozzle communicates with the biomass fixed-bed gasification reacting furnace burner hearth of downdraft, with the flowability that pumps in the insulating pipe preferably tar by civilian formula nozzle tar is fully atomized, enter equipment for gasification and carry out Pintsch process.
Vaporific liquid thermal tar is sprayed onto in the vapourizing furnace burner hearth and reacts with water vapour and carbon generating gasification behind the high-temperature zone, is converted into inflammable gas, so forms the successive coke tar cracking and purifies and recycle.
The present invention can concentrate recycle with depleted tar, improves the tar utilization ratio, is convenient to produce, and low cost of manufacture is fit to large-scale promotion application.
