The utility model discloses a water sample enrichment and cracking device and water sample DNA monitoring equipment, when carrying out water sample DNA monitoring, first through conveying assembly conveying water sample to be measured to make water sample flow through rich crack component, and then through rich crack component filtering water sample to carry out sample enrichment, then through conveying assembly extraction cracking solution to convey cracking solution to rich crack component, and then through rich crack component to the product of enrichment carries out cracking reaction, finally through conveying assembly extraction and convey cracking product to can carry out the subsequent storage, shift and detection of cracking product, through rich crack component and conveying assembly cooperation, through the accurate control to water sample and cracking solution, realized the automatic enrichment and cracking of water sample, relative to prior art, the monitoring process is quick and convenient, and the monitoring result error is small, and the practicality is strong, is suitable for extensive promotion and application.

This invention provides a biomass pyrolysis method, comprising the following steps: contacting biomass feedstock with carbon foam material, applying microwaves under an inert atmosphere to generate plasma with a temperature not lower than 3000K, causing the biomass feedstock to undergo a pyrolysis reaction; simultaneously, the volume ratio of the carbon foam material to the microwave power is 1:(25-500); wherein the unit of volume is cm³. 3 The unit of power is W. This biomass pyrolysis method has high conversion efficiency and high added value.

The utility model relates to the technical field of biomass energy conversion, disclose a kind of double fluidized bed biomass grading gasification system, comprising: pyrolysis fluidized bed carries out low-temperature pyrolysis to biomass, and by first cyclone separator, pyrolysis gas is sent into pyrolysis gas outlet, and solid matter is sent into first return feeder;Tubular reaction unit purifies the pyrolysis gas that flows;Gasification fluidized bed receives the pyrolysis gas that tubular reaction unit transports and the solid matter that first return feeder transports, after carrying out oxidation-reduction reaction, generate synthesis gas, and by second cyclone separator, synthesis gas is discharged and reused, and hot carrier in solid matter is returned pyrolysis fluidized bed by second return feeder;The gasification temperature in gasification fluidized bed is higher than the pyrolysis temperature in pyrolysis fluidized bed.The application is coupled by double fluidized bed design, realizes biomass grading pyrolysis and gasification, and tar content of synthesis gas is low;And the pyrolysis gas after purification is used as gasification agent, secondary use in gasification fluidized bed, save resources.
