Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Join shown in Fig. 1, present embodiments provides and remove tar in biological fuel gas conveyance conduit in a kind of coupled electricity-generation
Device, including the biological fuel gas conveyance conduit for being connect with biomass gasification device 1 and boiler 3, biological fuel gas conveying
Pipeline includes the pipeline 1 and pipeline 25 of parallel arrangement, one end of pipeline 1 and pipeline 25 pass through cooling pressurizing device 2 with
Biomass gasification device 1 connects, and the other end is connect with boiler 3, and pipeline 1 and pipeline 25 work alternatively, one of them is for firing
Gas conveying, another is used to remove tar removing；
One end that pipeline 1 and pipeline 25 are connect with cooling pressurizing device 2 is separately connected vapor by mixing duct 11
Conveyance conduit 8 and smoke conveying duct 9, vapor conveyance conduit 8 and smoke conveying duct 9 are drawn by boiler 3, vapor conveying
Pipeline 8, smoke conveying duct 9, mixing duct 11 junction be equipped with jet pipe 10, smoke conveying duct 9 convey high-temperature flue gas
It is mixed in mixing duct 11 using jet pipe volume 10 vapor that steam pipe 8 conveys that absorb water, and passes through mixing duct 11
Gaseous mixture is delivered in the pipeline of tar to be removed, the coke of inner wall of the pipe will be attached to using the gaseous mixture of tail gas and vapor
Oil dissolution evaporation to remove tarry impurities, and carbon monoxide and hydrogen that chemical reaction generates is sent into boiler and burnt.
The present embodiment removes the tar in pipeline by chemical method, and tar is mainly condensable polynuclear aromatic race, phenol
Class and olefin compound start to condense when temperature is less than 200 DEG C, these molecular structures are different and type is more.Outside
Under power effect, it is easier collision and is bonded together.The vapor and flue gas mixed gas of high temperature are chemically reacted with tar,
Production hydrogen and carbon monoxide and other gases, tar then resolve into other fuel gas, i.e. tar+vapor+cigarette
