The invention relates to a method for cleaning gas by means of fine-particle adsorbing agents in a flow reactor through which the gas that is to be cleaned flows in a turbulent manner. According to the inventive method, a velocity profile that comprises a core flow and an area which is located between the wall of the flow reactor and the core flow and in which the flow velocity is higher than that of the core flow, is created in the gas flow. The fine-particle adsorbing agents are fed into the area of the core flow. The invention also relates to a flow reactor for carrying out the inventive method.
Description
Technical field
The present invention relates to a kind of method of carrying out gas purification in flying flow reactor with meticulous adsorbent, flowing through to turbulence to be clean, this flies flow reactor.
Background technology
For example in aluminium industry, use such method that Fluoride Separation is come out.Meticulous alundum (Al (AL
2O
3) carry out suction-operated, after charging, fluoride can be imported reduction process and produce aluminium.
According to by method known among the US 4 501 599, the fine solid material that is used as adsorbent is fluidized in flying the feed tube of flow reactor, and is placed in the injector that flies flow reactor inside by one and is input into air-flow to be clean.These solid matters come out from the opening radial spray on the injector circumference, and are brought into air-flow.Air-flow is turbulent, and this is just flying to occur a substantially the same flow velocity on the entire cross section of flow reactor, and the solid matter of high concentration more or less is equally distributed.Loaded by very big wearing and tearing at this wall that flies flow reactor.
Summary of the invention
The objective of the invention is to, reduce the wearing and tearing that fly on the flow reactor wall by introducing a kind of method.
This purpose realizes by a kind of method with the described feature of beginning by the present invention, promptly, in air-flow, produce a velocity profile, this velocity profile has a core to flow, and between the wall that flies flow reactor and core flow, a zone being arranged, flow also to compare with core and have higher flow velocity in this zone; And and with in the meticulous adsorbent introduction core flow region.Adjustment mobile section according to the present invention impels the dilution in the wall near zone.For this reason, along with the flow equilibrium that the length of flow appearance of progression is flowed to core from the wall near zone, solid matter concentrates in the core flow region thus.Described these effects are supported by the following method, are about to meticulous adsorbent and introduce in the core flow region.Reach high solid substance concentration away from the wall that flies flow reactor by introducing method of the present invention.The wearing and tearing of wall load has just reduced thus.
Object of the present invention also relates to a flow reactor that flies that is suitable for implementing this method, comprising:
A container of flowing through by gas to be clean;
One in air-flow with the guider of chamber wall arrangement separated by a distance;
The feeding device that is used for meticulous adsorbent (Adsorbentien) that at least one is connected with guider;
Wherein, the gas guider of flowing through, this gas are compared lower flow velocity with one with the main flow that flows through on next door, the guider outside and are flowed out from guider on the gas flow direction of the container of flowing through, and the adsorbent that will send into the guider inner chamber is taken away together.These meticulous solid matters, are admitted in the air-flow with high solid substance concentration on the flow direction of gas flow to be purified according to the present invention, and the air-flow that does not contain solid matter that is had high flow velocities at this this feed air-flow coats.In this manner, can be by above-mentioned effect with high solid substance concentration away from wall.
Guider preferably constitutes passage in container both ends open and that flowed through by the shunting of gas to be clean.A large amount of solid matters slow down the air-flow in this zone, occur near the desired mobile section that has high flow rate wall thus.
Be also that in invention scope connection one is used for the gas pipeline of carrier gas on guider, the flow of this carrier gas can irrespectively be regulated with the air-flow of gas to be clean.Carrier gas also can be a gas to be clean.The gas flow that these are introduced by guider and flow through on next door, the guider outside can be regulated separately in this embodiment.Mobile section in flying flow reactor is changed.
According to a kind of preferred structure of the present invention, a plurality of feeding devices that are used for adsorbent are set, they are star-shaped to be connected with each perforate of guider shell side.Chute, vibratory sluice, conveyer belt or auger conveyor all can be used as feeding device.
Description of drawings
Explain the present invention below by the accompanying drawing that an embodiment only is shown.In the accompanying drawing:
Fig. 1 is the longitudinal section that flies flow reactor that is used for gas purification;
Fig. 2 be along Fig. 1 center line I-I intercepting sectional view;
Fig. 3 is another structure that flies flow reactor.
The specific embodiment
Flying flow reactor (Flugstromreaktor) shown in these figure, comprising container 1, a feeding device 4 that is used for meticulous (feinteilig) adsorbent that in air-flow, is connected with guider 3 of flowing through by gas to be clean 2 aspect its basic structure with the guider 3 and of chamber wall arrangement separated by a distance.Described feeding device 4 star-shaped each perforate with guider 3 shell side that are used for the fine solid material are connected, and are designed to chute, vibratory sluice, conveyer belt, auger conveyor or the like.
Guider 3 is by the gas percolation.Described gas longshore current flows out from guider through the gas flow direction of container 1, and the adsorbent of inserting guider 3 inner chambers is taken away.The flow velocity of effluent air/solid matter from guider-air-flow is less than the flow velocity of the air-flow that does not conform to solid matter that flows through from next door, guider 3 outsides.This has caused a velocity profile that schematically illustrates 5 in Fig. 1.As can be seen, produced a velocity profile 5 in air-flow from this diagram, this velocity profile has a core to flow 6, and flows with core at the wall that flies flow reactor and between 6 a zone 7 to be arranged, and it has higher flow velocity with comparing than core mobile 6.Meticulous adsorbent is introduced into the core flow region.Along with the length of flow (FliessLaenge) of progression, flow velocity 6 during core flows and the flow velocity 7 that centers in the mobile annular flow of core balance each other.One lateral flow that is orientated from outside to inside 8 is got in touch with the equilibrium phase of described velocity profile, and this lateral flow 8 is marked by flow arrow in Fig. 1.Concentrating of solid matter in the mobile nucleus of described lateral flow 8 supports.Simultaneously, the described lateral flow 8 of orientation from outside to inside also impels the gas from the wall near zone to contact with solid matter.
In the embodiment shown in Fig. 1 and 2, guider 3 constitutes passage in container 1 both ends open and that flowed through by the shunting of gas gas to be clean.Inserted a large amount of solid matters in the guider 3 and slowed down air-flow, occurred thus at the mobile section shown in Fig. 1 by guider 3.This configuration is particularly suitable for big solid matter mass flow.
In the embodiment shown in Fig. 3, connection one is used for the gas pipeline 9 of carrier gas on guider 3, and its flow can irrespectively be regulated with gas flow 2 to be clean.By regulating the delivery air-flow mobile section in flying flow reactor is changed, and it is conditioned with suitable manner.
