Use:
See also shown in Figure 1ly, pyrolysis gas of biomass is earlier through tornado dust collector 1, and centrifugal action is solid down, gas two is separated, and thick dust is thrown to around the tower body, because of than great 12 li in the fly-ash separator 1 tower body below ash bucket that falls into.Also have tiny dust to be taken away through cyclone dust removal, therefore adopt wet dedusting by air-flow.See also shown in Figure 2, pyrolysis gas of biomass is inhaled into from inlet pipe (Venturi tube) 23 tops earlier, attenuate because of diameter shrinks at larynx neck 2311, the very big formation negative pressure of gas velocity, the spray recirculated water that pump is made is drawn into, mix with pyrolysis gas of biomass, horn-like spreading area 2313 forms eddy current and turbulence state mixing in the lower end again then, arrived in the casing 21, volume enlarges, the separation of meeting of gas, water two washes away the dust in the pyrolysis gas of biomass mostly, and washing water are collected by high and low flowing automatically in the circulating water pool from casing 21 below pipes 22.Pyrolysis gas of biomass after the purification is sucked into upper right side gas, the water sepn packing layer 241 of casing 21, the moisture of taking away by filler hold back drop onto case at the bottom of, the pyrolysis gas of biomass after the purification enters shell and tube condensation fractionating tank 3.See also shown in Figure 3ly, pyrolysis gas of biomass does not only have dust through the front two-step purification, and temperature has reduced many.Enter in the jar 31, it at first is the leftward space that enters upper cover, it is separated by upper cover dividing plate 33, and pyrolysis gas of biomass can only flow to tank body 31 bottom head spaces along the half of tubulation in a left side, flows to the rightward space of tank body 31 top upper cover dividing plates 33 again along right half of tubulation.Tank body 31 has the clear water of coming from refrigeration cycle pond pump that the biogas in whole tubulations is cooled off, 2-3 this device of can connecting as required.Cooled pyrolysis gas of biomass just can be separated wood vinegar and wood tar oil.In order not allow outside air see in, underlying water seal bucket 32, its side is taken over and is allowed the collection that flows away of fractionated product.The tubulation here and sieve tray subassembly 34 are some tubulations 342 with upper and lower two sieve trays, 341 combinations after again sealing weld on tank body 31, becomes as a whole, assurance gas, water are respectively walked the road of each.Enter three-phase fluidization washing tower 4 again, see also shown in Figure 5,2 series connection as the case may be of this washing tower 4.After pyrolysis gas of biomass fractionates out wood vinegar and wood tar oil, still need degree of depth ground to remove wood tar oil and wood vinegar, " coking ", " scuffing of cylinder bore " and corrosion can take place otherwise enter engine cylinder.Pyrolysis gas of biomass is that the below from washing tower 4 is sucked into, at first be subjected to the atomized water spray washing of atomizer 45 ejections, then from bottom to top through 2 layers of light filler layer 43, mix in packing layer 43 with upper and lower 2 row's showers 44 spray waters, mass transfer, wood tar oil in the pyrolysis gas of biomass and wood vinegar are dissolved in the spray water, make its purification.Gas, liquid and filler (Gu) the three-phase relative movement, form the three-phase fluidization state.Pyrolysis gas of biomass after the purification fails to be convened for lack of a quorum and takes away small amount of moisture, in the 3rd layer of packing layer most of water is retained down, and drips to 4 ends of washing tower.Spray water is to recycle and accomplish that environmental purification handles, and with pump water is driven in the tower as shown in Figure 5 three positions, upper, middle and lower, and backwater is to flow automatically to circulating water pool from 4 ends of washing tower under by height.Vacuum pump 5 is arranged on after the three-phase fluidization washing tower 4, make total system all suction type work under negative pressure of all facilities before this pump 5, otherwise all centrifugal blower to be installed before each processing unit equipment, this is irrational, and the front just go out pyrolyzer pyrolysis gas of biomass temperature up to 650 ℃, general centrifugal blower can't bear high temperature like this.Because work in 24 hours, this pump must be provided with 2, and the using and the reserved are used alternatingly.Being connected on after 2 vacuum pumps 5 is hydrolock automatic constant-pressure gas holder 6, see also shown in Figure 6, by tube 63, water seal tank 61, inlet pipe 62, unload pressure pipe 64, three standard fire insulation valves 67, tensimeter 66 and safety valve 65 are formed.Purify artifact matter pyrolysis gas and must store adjusting air demand and pressure, guarantee that the engine air feed is constant with gas holder.Pyrolysis gas of biomass after the purification pumps into hydrolock automatic constant-pressure cabinet 6 by vacuum pump 5, is air storage under the positive pressure.Pass water seal tank 61 through inlet pipe 62 and enter tube 63, tube 63 upwards pressure and is and acts on a pressure opposite sign but equal magnitude of interior water seal tank 61 waters surface, at this moment release water absorption tube 64 just has water in tube 63 top ejections, and it is constant to remain tube 63 air pressure inside.When just beginning not have pyrolysis gas of biomass, tube 63 weight make its height that falls into the pond a certain design in bottom, and air is compressed to a certain degree maintenance balance in the tube 63.When the pyrolysis gas of biomass input, tube 63 is subjected to the gas upward pressure upwards to float, gas is many more highly more floating, when levitation height makes release water absorption tube 64 exceed the water surface, pyrolysis gas of biomass will all be gone to the ambient atmosphere from release water absorption tube 64 and go, automatically unloading is to original original state, and tube 63 falls into the home position, bottom of water seal tank 61 at once.As long as pyrolysis gas of biomass has been arranged, can be through 3 fire insulation valve 67 pipelines output air feed be housed, wherein one is for the personal gas of roasting kiln; Another strand is for engine power generation.All receive and use the gas place, use valve regulated with rubber hose.For safer, tensimeter 66 is set shows, also can connect warning.Safety valve 65 is set simultaneously.Water seal tank 61 is used skeleton construction, is arranged on underground certain projected depth, reduces the rising height of tube 63, otherwise too high.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
