Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Shown in Fig. 1-2.
A kind of biomass waste digestion reaction system, it comprises reactor drum 1, low pressure gasholder 2, biogas compressor 3 and high pressure tank 4, described reactor drum 1 comprises housing 5; Be provided with the separated retaining 6 that its content is separated into rising yield zone and decline yield zone in the described housing 5; Can adopt the brick brick wall structure that forms at a distance from retaining 6, also can adopt corrosion-resistant plate manufacturing to form, be provided with material inlet by the rising yield zone that is separated at a distance from retaining 6; The decline yield zone is provided with material outlet, and is as shown in Figure 1.In the said housing 5, be provided with collecting methane chamber 7 at a distance from retaining 6 top; Collecting methane chamber 7 links to each other with the input terminus of gas equipment and the input terminus of low pressure gasholder 2 through tracheae simultaneously; (can adopt output pressure is that the common compressor of 5-10 kilogram realizes for the output terminal of low pressure gasholder 2 and biogas compressor 3; This compressor is working medium with biogas) input terminus link to each other, the output terminal of biogas compressor 3 links to each other with the input terminus of high pressure tank 4; On retaining 6, runner 8 is installed described, a side of runner 8 is arranged in described rising yield zone, and opposite side is arranged in described decline yield zone; On the runner 8 blade is installed; In described rising yield zone, the bottom of said runner 8 installs nozzle 9, the air outlet of nozzle 9 and the bottom of blade drive runner 8 with driven vane relatively and rotate, said nozzle 9 passes through tracheae and links to each other with the outlet side of high pressure tank 4; As shown in Figure 1; In order to improve mixing effect, can 1-5 layer runner 8 (among Fig. 1 being 3 layers) be installed according to the height of digestion reactor with at a distance from the height that keeps off 6 during practical implementation; The quantity of every layer of runner 8 can be made up of the runner of 1-5 parallel installation, and the runner 8 of three parallel installations is arranged among Fig. 2.
Principle of work of the present invention is:
Be divided into two portions with partition wall (promptly at a distance from retaining 6) in the reactor drum, some runners are set on partition wall, have blade on the runner, drive runner by compressed biogas jet impact blade and rotate, thereby the solid-liquid system in the reactor drum is stirred.
Partition wall both sides in reactor drum are respectively moving district of digestion material upwelling and decline yield zone: in the rising yield zone, runner is compressed biogas driving drive solidliquid mixture and upwards flows, and stirs disturbance by the blade that distributes on the runner simultaneously; Get into the moving district of katabatic drainage after flowing to the partition wall end face on the solid-liquid material, runner promotes flowing downward of material in rotation process, and stirs disturbance by the blade that distributes on the runner.Reactor inner space more than the partition wall top is the biogas chamber; Draw by the biogas pipe; Shunting one tunnel gets into low pressure gasholder on the biogas fairlead; By the biogas compressor boost is compressed biogas, through being incorporated into the runner downside in the reactor drum by the compressed biogas pipe after the high pressure tank voltage stabilizing, through the jet drive runner motion that makes progress of biogas nozzle.
Innovative point of the present invention mainly contains:
(1) vertical partition wall is set in the biomass waste digestion reactor drum, with being divided into two intervals in the reactor drum, the rising yield zone that the interval is the biomass waste solid-liquid, another is interval to be the decline yield zone.Reactor shell can be cylindrical or square structure.
(2) runner perpendicular to the ground is installed in partition wall, half of runner is at the rising yield zone, and second half of runner arranged blade at the decline yield zone on runner.
(3) in the bottom of runner the compressed biogas nozzle is set; Biogas by the biogas nozzle ejection is ejected into drive runner rotation on the runner bucket; The solidliquid mixture of promotion in the rising yield zone forms overall flow upwards; Solidliquid mixture in the decline yield zone forms downward overall flow, and by the runner blade solidliquid mixture is stirred.
(4) on partition wall, 1～5 layer of runner can be set vertically, several 1～5 of every layer of runner.
(5) biogas from digestion reactor output draws one tunnel entering low pressure gasholder, by biogas compressor boost to 5～10 kilogram pressure, after the high pressure tank voltage stabilizing, gets into reactor drum and guides to the runner bottom through the biogas pipe, through nozzle runner is driven.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
