Specific embodiment
Completely illustrate the present invention by way of example and in conjunction with the accompanying drawings to become apparent from.
Fig. 1,2,3,4 show the structure chart of tar separator in a kind of pair of pyrolytic gasification gaseous mixture.It is this right in figure The device of tar separation includes ontology, air inlet acceleration mechanism and a central tube 5 in pyrolytic gasification gaseous mixture.Ontology successively uses Inferior pyramidal body 1, lower cylinder 2, epicone body 3 and upper cylinder 4 are fixedly connected integrally, air inlet pipe 2a and lower cylinder Body 2 is tangentially fixedly connected, and the bottom plate of inferior pyramidal body 1 is equipped with air inlet acceleration mechanism and drain valve 7, the side of upper cylinder 4 Equipped with a leptospira structure 4a tangentially connected with discharge pipe 4b.Central tube 5 is located at the medium position of ontology, central tube 5 Top is fixedly connected with the top plate of upper cylinder 4, and the cone 5a of lower part is reached always lower 2 intake pipe 2a's of cylinder Corresponding position, 5 end-enclosed of central tube above upper 4 top plate of cylinder, laterally attached escape pipe 5c, in upper cylinder Central tube 5 below 4 top plates is equipped with the tangential port 5b of favorable current, during tangential port 5b is evenly arranged on using axial multiple rows of circumferential direction On heart pipe 5.
Air inlet acceleration mechanism is fixed on motor 6 plate outer side of inferior pyramidal body 1, and the transmission shaft 6c of motor 6 protrudes into lower cone Driving flabellum 6c rotation in body 1, transmission shaft 6b are supported by being fixed on the support base 6a on the inside of 1 bottom plate of inferior pyramidal body.
Central tube 5 in upper cylinder 4 is equipped with the uniformly distributed tangential port 5b of 4 row's circumferential directions, on the top of epicone body 3 Corresponding central tube 5 is equipped with the uniformly distributed tangential port 5b of 1 row's circumferential direction.
This working method to the device of tar separation in pyrolytic gasification gaseous mixture, when mixed gas is flowed from air inlet pipe 2a When entering ontology, since body construction and air inlet acceleration mechanism force air-flow to do circle rotation movement, mixed gas carry out enrichment and It suspends, does circumference and ascending motion along the outer wall and central tube 5 of ontology, the big gas of quality can be by the small gas of quality in Heart pipe 5 drives pressure, and the big gas of quality can be distributed in the periphery of the small gas of quality, and constantly assembles and be concentrated;When gas quilt When enrichment suspension is risen in epicone body 3, mixed gas is further speeded up, and mixed gas is in the environment of rotating rising Into upper cylinder 4, the biggish tar of quality is drawn by the tangential direction of gas rotating by discharge pipe 4b and tar water water steams Gas, by escape pipe 5c by tangential port 5b central tube 5 draw the lesser gas of quality, thus in mixed gas tar and Tar vapor is separated.
Using above-mentioned technical solution, when mixed gas is entered with certain air velocity, due to body construction and into The effect of gas acceleration mechanism causes air-flow forced to do circle rotation movement.Effect of each mixed gas in centrifugal force and centripetal force Under, it is effectively enriched with and is suspended according to the regularity of distribution of molecular brownian motion.Under the promotion of thermodynamics kinetic energy, gas meeting Circumference and ascending motion are done along the outer wall and central tube of ontology.It is analyzed according to Blang's molecular motion Distribution Principle:Limited In space, the small gas of quality can be driven to central area and be pressed by the big gas of quality;And according to Newton's second law and centrifugal force With the action principle of centripetal force:The big gas of quality can be distributed in the periphery of the small gas of quality, and constantly assemble and be concentrated; And the small gas of quality drives pressure at it and also assembles constantly around central tube.It is risen to centainly when gas is suspended by enrichment When degree, it is introduced into the epicone body of small diameter, accelerates mixed gas faster.Mixed gas rises in rotation In the environment of enter upper cylinder, draw the biggish tar of quality and tar water by the tangential direction of gas rotating by discharge pipe Vapor, by escape pipe by tangential port central tube draw the lesser gas of quality, thus in mixed gas tar and Tar vapor is separated.
The method that tar and tar vapor regasify cracking is as follows:The tar and tar vapor drawn from discharge pipe, In the environment of keeping the temperature 200-240C °, pyrolysis gasification furnace stone or metal plate for standing a stove on as a precaution against fire bottom is input by pipeline, is directly entered its redox Layer in, carried out without catalyst weight thermal cracking gasification, generate with CH4 gas be advocate peace a small amount of CO, H2 substance high heating value combustion Gas.
