The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
Detailed description of the invention
Fig. 1 is the application implementation that the method for tar in biological fuel gas conveyance conduit is removed in coupled electricity-generation of the present invention
Example.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Present embodiments provide a kind of method that tar in biological fuel gas conveyance conduit is removed in coupled electricity-generation, comprising:
Two parallel biomass are set between the biomass gasification device and boiler in biomass coupled electricity-generation system
Fuel gas transportation pipeline controls two pipelines by electric-control stop valve and works alternatively, one of them is used for fuel gas transmission, another use
In except tar removing；And pressure sensor is respectively set close to boiler side in two pipelines, by the pressure change of pressure sensor,
The switching action for executing two pipelines switches pipeline when the pipeline pressure amplitude of variation of normal delivery of fuel gas is larger.
High-temperature tail gas (flue gas) all the way and all the way vapor are drawn from boiler, makes tail gas volume water suction steam using jet pipe, leads to
It crosses mixing duct to enter 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
Gas --- hydrogen+carbon monoxide+other gases.
In biomass coupled electricity-generation system, vapor and flue gas are primary products, and the present embodiment goes to devoke using product
Oil can be to avoid detergent, filtrate be used, and water etc. removes tar removing, and avoiding a large amount of waste water of generation causes to pollute, and is also avoided
Often replacement detergent, the higher cost that the materials such as filtrate generate.Also, flue-gas temperature is not reduced more, saved big
The heat of amount.Meanwhile the tar deposited in the duct has also obtained effective utilization, the hot generating efficiency of system greatly improves.
Join shown in Fig. 1, the device for removing tar in biological fuel gas conveyance conduit in gasification of biomass coupled electricity-generation includes
