On condensation water tank, there are water-in and water outlet.Cleaning apparatus inside is provided with the parallel filtering net of many groups, and the angle of filtering net and horizontal plane is α, and 90 °≤α≤150 °, the bottom of cleaning apparatus is provided with material storing cavity and closing device, and the middle part of filtering net is fixed with vibrator.Vibrator is vibrating motor or electromagnetic vibrator.Closing device is weight turner or electric butterfly valve.
Compared with prior art, the utility model biomass gas purifying cleaning apparatus has the following advantages: this device is provided with the device of catalytic tar in burner hearth, the pollution substances such as tar can be cracked into inflammable gas again, pollution and peculiar smell are reduced, the steam unit that dewaters of condenser, can improve burning of gas quality.Burner hearth inner and outer air pressure is poor little, can not produce the danger such as blast.Refining plant can filter out fine solid particle greatly, thereby has reduced the pollution to environment.The utlity model has cost low, simple in structure, depuration quality advantages of higher.
Brief description of the drawings
Fig. 1 is the one-piece construction schematic diagram of the utility model biomass gas purifying cleaning apparatus;
Fig. 2 is filter screen structure schematic diagram in cleaning apparatus in the utility model biomass gas purifying cleaning apparatus.
Embodiment
In brief description of the drawings, label 1 is body of heater, the 2nd, and pipeline, the 3rd, tar purification device, the 4th, condensing works, the 5th, condensation water tank, the 6th, the water-in of condensation water tank, the 7th, the water outlet of condensation water tank, the 8th, ash discharge capping, the 9th, Y-junction, the 10th, U-shaped fluid-tight, the 11st, gas blower, the 12nd, Nonreturn fan cover, the 13rd, inlet pipe, the 14th, cleaning apparatus, the 15th, filtering net, the 16th, the mouth of pipe of giving vent to anger, the 17th, vibrator, the 18th, material storing cavity, the 19th, closing device.
Below in conjunction with the drawings and specific embodiments, the utility model biomass gas purifying cleaning apparatus is described further: as shown in the figure, the present embodiment in use, need to open bell, biological material is added in burner hearth, ignite for the first time and needn't add too much, light biological material, then cover bell, in sealed cistern, pour into appropriate water, can prevent that the gas generating from exposing from gap.The now ash discharge capping of ash discharging hole must cover, then start gas blower, air quantity flows from down to up from burner hearth bottom, driving a reaction gas overflows from the transmission pipeline of burner hearth upper end, air-flow can travel back across burner hearth internal high temperature district again along transmission pipeline, under the effect of catalyzer, when temperature reaches 750 DEG C-900 DEG C, can there is cracking in the tar in air-flow, generate permanent gases and inflammable gas in tar purification device.
