The specific embodiment
Below with reference to the accompanying drawings and read after the present invention describes in detail, will understand these and other feature of the present invention and advantage better.
According to Fig. 1, described graphic demonstration incinerator (10), the ash collection means (30) that it comprises the case (20) that is positioned at the top and is positioned at the below, the wherein said case (20) that is positioned at the top be to be used to the to burn combustion chamber of combustible material or rubbish; Material feed-in opening (22), it is positioned on the top, is used for combustible material or rubbish are introduced incinerator (10); A lid (23), it hides incinerator (10) during burning; Gas storage case (24), it is positioned at the top margin of case (20), is directed to filter element with the fuel gas that produced of storage and with fuel gas; With air supply compartment (25), it has a plurality of air intakes (26) to help burning around the bottom of case (20).
In the process of burning, can combustible material or rubbish be condemned via material feed-in opening (21) and send and compress and introduce incinerator (10), or or rather, be introduced case (20).Before combustion process, fill up fully but must will go up burning device (20) with combustible material or rubbish.In case with combustible material or rubbish case (20) is filled up fully, this accommodating device will close ， And and, air will be transported from those air intakes (26) of being positioned at this accommodating device bottom and enter this accommodating device.Will fire be introduced receptacle means (20) via the bottom ambient air inlet (26) that is positioned at receptacle means (20).Produce and the temperature increase up to gas, till baking or distil flammable material and then generation fuel gas, during burning process, air can be continuously pumped into air supply compartment (25) and by described air intake air be pushed described receptacle means.During burning, guarantee that lid (23) is closed always.Combustion process can take place always, has all become ashes up to all combustible materials or rubbish, and described ashes fall into down in the ash collection means (30) and correspondingly disposed.Burning process in this incinerator (10) can produce minimum ashes and it is smoke-free and tasteless.
According to Fig. 1, incinerator (10) is preferably cylindrical, and is completely cut off, and to avoid the loss of heat, it has thicker heat shield (27) as the outer wall that bears the heat that is produced by burning.This heat shield covers the whole incinerator (10) that comprises receptacle means (20) and following ash collection means (30).Receptacle means (20) further comprises another layer wall, its fire proofing tile as inwall (28).Because burning occurs in the receptacle means (20), therefore be necessary to have another layer wall, be used for protection.Described wall further comprises a pool interlayer (21), and it is around the solar heat protection outer wall.This layer water serves as the cooling agent of described incinerator, to reduce the temperature of incinerator wall.Therefore, for safety, the temperature of described incinerator (10) can be the same not high with the inside of incinerator (10).In addition, the existence of water layer has been arranged, the durability of described incinerator (10) is longer.Water in the described water layer also can be used as thermal water resource to be used for life.Place, the top of described pool interlayer (21) has tap (showing) herein, be used to move the water to flow into, and place, the bottom of described pool interlayer (21) has outlet (showing) herein, is used for making where necessary the hot water outflow.Place, top in receptacle means (20) also has dust cap (29).
The combination of Fig. 1 to Fig. 4 shows combustible gas production system.During burning process, will produce fuel gas.Because from the air that the air intake (26) of the bottom of described case (20) enters continuously, this combustible gas cognition is pulled to the top of receptacle means (20).The atmosphere storage that is produced is in gas storage case (24) as shown in Figure 2.According to Fig. 3, this gas storage case (24) is connected to and is positioned at the outside air shooter (40) of incinerator (10).Filter element (50) also is positioned at the outside of incinerator (10), and this filter element (50) is used for before use gas being filtered.
According to shown in Figure 4, filter element (50) is connected with described incinerator by air shooter (40).Filter element comprises the internal vertical duct (51) that is positioned in the middle of the filter element (50), and a water chamber is positioned at the bottom part of this filter element, and exterior chamber (52), and it has tap (53), is used for removing the water that filter element (50) overflows.This water chamber further comprises at least one tap, and to be used to remove contaminated water, internal vertical duct (51) is collected fuel gas at the opening (54) that the place, bottom has the size broad with the space that broad is provided.Internal gas conduit (51) the from then on opening of broad (54) extends to form conical catheter (55) to the direction of vertical conduit (56).This internal vertical duct (51) further comprises side conduit (57) at the top, and this side conduit (57) is directed to fuel gas in another compartment (not shown), for use.
Along with fuel gas enters filter element (50), filter process will begin.Fuel gas at first will be moved down into the bottom of filter element along with the cyclonic motion around the described internal vertical duct.When fuel gas and the water (70) at bottom place that is placed on described filter element (50) when contact, the filter process generation.Then, filtered fuel gas will be moved upwards up in the broad opening (54) of internal vertical duct (51), and because the power that the cyclone effect causes in the filter element (50), filtered fuel gas will further be moved upwards up in the vertical conduit (56) via conical catheter (55).At last, to transfer in another compartment for use, described side conduit (57) is the outlet of the top edge of internal vertical duct (51) to filtered fuel gas with approaching side conduit (57).This filtered fuel gas can be used for cooking purpose or as the energy.Fuel gas is smokeless, and flame is arranged or do not have flame when burning.
As shown in Figure 4, before filter process, water is placed in the filter element (50), it covers the part of the described broad size end of described internal vertical duct.Along with filter process carries out, will produce increasing water.This water will flow in the exterior chamber (52), and by using tap (53), the water that overflows will be removed.
Should be appreciated that the present invention can other particular form implement, and be not limited to unique embodiment mentioned above.Yet, the modification of the notion that is disclosed and be equal to replacement, for example one of skill in the art expect easily those, wish to comprise within the scope of the appended claims.
