Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
With reference to figure 1, biomass pyrolytic air purifying apparatus of the present utility model, it is from left to right successively including one cyclonic point From device 1, secondary cyclone 2, water washing tank 3 and condenser 4;
The air inlet of the one cyclonic filter 1 is connected with the gas outlet of a biomass pyrolysis furnace, primary cyclone 1 Gas outlet be connected with the air inlet of two level cyclone filter 2, the gas outlet of two level cyclone filter 2 and be arranged on water washing tank 3 The air inlet connection of bottom, the inner upper of water washing tank 3 were provided with filtering barrier, and this crosses filtering barrier includes nylon monofilament from the bottom up Stratum reticulare 31 and activated carbon filter layer 32, cross filtering barrier and divide water washing tank 3 for underlying primary water wash zone A and above Two level water wash zone B, the top of water washing tank 3 are provided with gas outlet and clear water entrance, pass through an air-introduced machine (not shown in figures) And the gas in water washing tank 3 is introduced to the air inlet of condenser by gas outlet.By this structure, pass through biomass thermal The gas in stove out is solved then in turn by primary cyclone, secondary cyclone, water washing tank and condenser, finally The combustion gas of cleaning is flowed out by the outlet of condenser and stored.
The bottom of water washing tank 3 is provided with liquid outlet, and the liquid outlet connects with wastewater collection pond 5, in waste collection pond Middle part is provided with baffle plate 51 so that wastewater collection pond is divided into interconnected waste and clear water recovery area, the upper opening of baffle plate Place is provided with filter core 52, and water pump is provided with clear water recovery area so that the liquid circulation in clear water recovery area is flow at the top of water washing tank Clear water entrance, by this structure, because the gravity of tar is bigger than water, thus tar will fall at the bottom of waste when standing Portion, the clear water on top when reaching certain liquid level and by filter core after enter clear water recovery area.
By said structure of the present utility model, first by primary cyclone and secondary cyclone by biology Dust and magazine in the pyrolysis gas of matter pyrolysis oven are separated so that by what is flowed out in gas outlet in secondary cyclone Gas is pure gas;Then, the gas after separation, which enters in water washing tank, carries out washing decoking processing, first in gas The condensable tar of major part condensed to the cold in the primary water wash zone of water washing tank, then remaining partial condensation gas enters back into Two level washing process is carried out to two level water wash zone B;Gas after water washing tank is handled is entered in condenser, the water in gas Steam is flowed into wastewater disposal basin after condensing to the cold and collected.
The utility model is had the benefit that by the use of water washing tank:Water washing tank is divided into just by crossing filtering barrier Level water wash zone and two level water wash zone, because most of condensed gas in gas can be condensed into tar in primary water wash zone, and In primary water wash zone, effect of the tar of condensation due to crossing filtering barrier is not compromised by the flowing of gas and flows into two level water Area is washed, thus the tar-concentration of primary water wash zone is greatly more than the concentration of tar in two level water wash zone.When primary water wash zone is burnt When the concentration of oil is much, then it can be flowed into by washing the liquid outlet of pot bottom in wastewater collection pond, now, two level washing Liquid in area can be then flowed into primary water wash zone, while clear water can be flowed into two level water wash zone.Pass through the water of this structure Cleaning of evaporator, water source can be greatly saved, avoid the waste of water resource so that clear water is on the basis of condensed tar is ensured and most Used to limits, and due to high containing tar-concentration, thus the extraction efficiency of tar greatly improves.In addition, in order to enter one Step ensures the condensation extraction effect of tar in gas, the clear water entrance of water washing tank and the spray equipment for being arranged on water washing tank inner top Connection.
In order that the water washing tank for obtaining purifier of the present utility model has more preferable using effect, it is dismantled and assembled to cross filtering barrier Ground is arranged on inside the water washing tank, and specifically, washing top tank structure is convex to be provided with multiple positive stops, crosses filtering barrier and is placed on institute State on positive stop.By this structure, to crossing filtering barrier can change in time when long-time uses so that it is guaranteed that its Absorption and the effect of isolation tar.
For the more enough concentration for observing tar in primary water wash zone in water washing tank in time, water washing tank corresponds to primary water wash zone Visual windows are provided with side wall.The visual windows are sealingly engaged into water washing tank, and the visual windows can be resistant to elevated temperatures glass Glass material.
In a preferred embodiment, the delivery port of condenser connects with wastewater collection pond, has saved water source.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details The scope of restriction.
