Description
Technical field
The utility model relates to a kind of air supply device, relates in particular to a kind of for 50～100m
3Big-and-middle-sized loose shape or particulate state straw or domestic refuse are the many valves air supply device on the vapourizing furnace (gas producer) of fuel.
Background technology
Structural shape take straw or domestic refuse as the vapourizing furnace (or gas producer) of crude fuel has tens of kinds at present, in order to make fuel sufficient combustion generation fission become combustion gas, usually the thorax lower end is equipped with valve with air feed in stove in stove, according to present As-Is analysis, this valve is single body, do not form valve series, this single body valve can also be played a role for small evaporator stove (or gas producer), and for capacity at 50～100m
3Vapourizing furnace will inevitably cause air feed not enough or inhomogeneous with it.Before the utility model, yet there are no the relevant report of relevant combined valve (being many valves).
Summary of the invention
The task that the utility model need solve provides a kind of abundant air feed and air feed uniformly to be applicable to many valves of the vapourizing furnace air supply device on the big-and-middle-sized vapourizing furnace.
For finishing above-mentioned task the technical solution adopted in the utility model be: described a kind of many valves of vapourizing furnace air supply device comprises blower fan, blast tube, lower through-tube, the second ring pipe, the 3rd ring pipe, valve, the first ring pipe, upper siphunculus, external thermal insulation, inner thermal insulating layer and the airduct that intersects, external thermal insulation is coated with the internal layer that is contained in the stove inwall, the upper siphunculus that communicates with each other and lower through-tube are installed in external thermal insulation with between the inner thermal insulating layer, two of blast tube is communicated with respectively blower fan and upper siphunculus and lower through-tube, upper siphunculus and lower through-tube with intersect airduct and be communicated with, on the intersection airduct, be communicated with successively the first ring pipe, the second ring pipe and the 3rd ring pipe are intersecting airduct, the first ring pipe, quantity is installed greater than 1 valve on the second ring pipe and the 3rd ring pipe.
Adopt a kind of many valves of vapourizing furnace air supply device that as above technical scheme provides compared with prior art, technique effect is:
1. applied widely.Can manufacture and design according to the different type of furnaces many valves air supply device of different specification size, satisfy the demand of various vapourizing furnaces.
2. air feed is stable, even.Because designed each layer air feed circulating line of described many valves air supply device can be in same plane, also can be not in same plane, can select according to the aspect ratio of dissimilar vapourizing furnace (gas producer), can satisfy the homogeneity of its wind supply quantity and air feed fully.
3. accelerate the combustionvelocity of raw material.The outside air of sending into each air feed circulating line from (speed change) blower fan can be accelerated burning and the fission reaction of former (combustion) material through preheating, improves aerogenesis speed.
Description of drawings
Fig. 1 is the schematic layout pattern of a kind of many valves of vapourizing furnace air supply device described in the utility model, also is Figure of abstract of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Described a kind of many valves of vapourizing furnace air supply device comprises blower fan 1, blast tube 2, lower through-tube 3, the second ring pipe 4, the 3rd ring pipe 5, valve 6, the first ring pipe 7, upper siphunculus 8, external thermal insulation 9, inner thermal insulating layer 10 and the airduct 11 that intersects, be coated with at the internal layer of stove inwall 12 external thermal insulation 9 is housed, the upper siphunculus 8 and the lower through-tube 3 that communicate with each other are installed between external thermal insulation 9 and inner thermal insulating layer 10, and two of blast tube 2 is communicated with respectively blower fan 1 and upper siphunculus 8 and lower through-tube 3.The wind of being sent by blower fan (speed-changing draught fan) 1 enters respectively upper siphunculus 8 and lower through-tube 3 through blast tube 2 and externally the wind comes from and carry out preheating.Upper siphunculus 8 and lower through-tube 3 with intersect airduct 11 and be communicated with, airduct 11 the bests of wherein intersecting are used first the decussation airduct.Arrange in the same plane that two transposition arms of intersection airduct 11 can be straight shapes, it can also be the transposition arm that the semicircle hat is not arranged in same plane, on intersection airduct 11, be communicated with successively the first ring pipe 7, the second ring pipe 4 and the 3rd ring pipe 5, shape design according to intersection airduct 11, the first ring pipe 7, the second ring pipe 4 and the 3rd ring pipe 5 threes can be arranged in the same plane or not in same plane, and the first ring pipe 7, the second ring pipe 4 and the 3rd ring pipe 5 spacing each other is optimum for equating, also can be unequal.Intersect even or non-homogeneous on airduct 11, the first ring pipe 7, the second ring pipe 4 and the 3rd ring pipe 5 (optimum for evenly) quantity is installed greater than 1 valve 6, wherein valve 6 can be selected ZL201220007557.4 " the anti-blocking valve of vapourizing furnace ", also can or require otherwise designed according to the different type of furnaces.
