Description
Technical field
The utility model relates to a kind of even gas distribution field, more particularly, relates to a kind of gas-solid two-phase bed flue gas even distribution device of the even gas distribution that maximizes.
Background technology
It is even that the operation of the high-efficiency and economic of common gas-solid two-phase bed depends on the gas distribution of distribution device, and the even distribution of gas phase not only depends on the gas distribution uniformity of distribution device self, also depend on the uniformity of solid phase bed, namely each to porous nickel distribute, do not pile up the larger punch block in closely knit dead band and space.
Gas-solid two-phase moving bed distribution device mainly adopts the pipe laying with qi-emitting hole, or utilizes the even gas distribution of the hole realization gas phase between the material distribution plate.Pipe laying gas distribution uniformity with qi-emitting hole will be got well, but the cloth atmidometer is larger, and dust content in the gas phase is had higher requirements, and is prone to the qi-emitting hole blockage problem; When directly utilizing the hole gas distribution of material distribution plate bottom, the gas distribution uniformity is slightly poor, and the air inlet cross-sectional area is less, the fast resistance of local velocity is large, and the gas phase flow velocity is larger, easily takes the dust in the solid phase out of, cause the gas phase dust greatly to increase, advantage is simple in structure, material bed good uniformity.
For large-scale gas-solid two-phase bed bed, when it adopted the pipe laying gas distribution, the resistance of its air inlet port was huge, and pipe laying is oversize, affects the collection of bed material; When it adopted the hole gas distribution, excessive because of the area of maximization gas-solid two-phase bed, the even distribution of gas was difficult to realize.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of gas-solid two-phase bed flue gas even distribution device of the even gas distribution that maximizes is provided, and it is effective, stable, simple in structure to maximization gas-solid two-phase bed bed gas distribution.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of gas-solid two-phase bed of the even gas distribution that maximizes is comprised of wallboard, material bed, hopper, offers the cloth gas port on the hopper wallboard.
Described cloth gas port is to press in hopper wallboard upper punch to form, and it can be one or parallel a plurality of, is long and narrow interruption perforate.
Top and side at qi-emitting hole are provided with the gas distribution baffle plate, are used for preventing that solid material from discharging or stopping up the cloth gas port from the cloth gas port, and the angle of described gas distribution baffle plate is less than hopper wallboard angle, greater than the solid material natural repose angle.
Described bucket wall board mounting structure is symmetrical, and offer cloth gas port position on every block of plate, area is identical.
The beneficial effects of the utility model are:
1, the induction air flow ratio of distribution device reduces, and local resistance reduces.
2, gas distribution is effective.Distribution device is positioned at material bed below and is evenly arranged, and has improved the uniformity of gas distribution;
3, stable.The dust of carrying secretly in the flue gas can be held back by solid material, and effluxes with material in silo, can enrichment in distribution device, can realize long-term stable operation.
4, simple and reliable for structure.Whole distribution device is comprised of the steel plate splicing of several perforates, and is simple in structure, and structural strength is good, can realize the application needs of large tracts of land bed.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the schematic diagram of hopper of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Such as Fig. 1, a kind of gas-solid two-phase bed flue gas even distribution device of the even gas distribution that maximizes is comprised of wallboard 1, material bed 2, hopper 3.As shown in Figure 2, hopper 3 comprises four hopper wallboard 3-1 and bottom material pipe 3-4, and hopper wallboard 3-1 is provided with gas distribution baffle plate 3-2, cloth gas port 3-3.
Described hopper wallboard 3-1 is positioned at gas-solid two-phase bed material bed below, and the wallboard angle of inclination can guarantee that greater than the natural repose angle of solid material the material of bed can draw off bed by hopper; The hopper wallboard all has in all directions of material, and how many its sizes selected according to the size of discharging quantity, discharge rate or cloth tolerance with.
Described four bucket wall plate 3-1 and bottom material pipe 3-4 are welded, equally distributed slit is arranged as cloth gas port 3-3 on the hopper wallboard 3-1, cloth gas port 3-3 is by pressing the long and narrow slit that forms in hopper wallboard upper punch, it can make according to the length of slit the slit of a slit or many interruptions.It can be one or parallel a plurality of, and the area in long and narrow slit determines according to the tolerance of gas distribution, the local velocity when purpose reduces gas and enters;
At described cloth gas port 3-3, be more nearside of slit and solid material, top is welded with gas distribution baffle plate 3-2, has in top and the side of slit, has effectively blocked the possibility of solid material by narrow slit flow discharge bucket or obstruction cloth gas port.The angle of gas distribution baffle plate is less than hopper wallboard angle, greater than the solid material natural repose angle;
The gas-solid two-phase bed of the even gas distribution of described maximization, its gas-solid two-phase bed bed gas distribution is effective, stable, simple in structure.
Take the maximization gas-solid two-phase bed bed gas distribution of typical gas cleaning, gas drying as example, adopt granular adsorbent (physical absorption, chemisorbed or both have both at the same time) as solid material, gas or the flue gas of processing to be clean, dry, pass the material bed that granular adsorbent forms from bottom to top, adsorb saturated or lose adsorbing material and discharge gas-solid two-phase bed by hopper bottom material pipe, the top granular adsorbent continues to add keeps gas-solid two-phase bed thickness of bed layer.The empty bed flow velocity of gas-solid two-phase bed bed gas overcurrent of even gas distribution of maximizing is generally 0.5m/s, and the gas-solid two-phase bed bed of the even gas distribution that maximizes is wide to be 7.2m, and long 51m, silo are of a size of square centrum, 12 * 85 the individual layers layouts of being inverted of 0.6 * 0.6m.
Hopper monomer four sides air inlet of the present utility model, single hopper wallboard air inlet port dimensions is 2 500 * 5mm, 2 400 * 5mm, area 0.009 m
2, totally 4.The air inlet sectional area amounts to 37.62m
2, the import flue gas flow rate is 5m/s; Under the identical set condition, as adopting the buried tube type induction air flow ratio up to 11m/s, local flue gas resistance is greatly diminished, and inevitably the material dead band can occur on pipe laying top simultaneously; And when making smoke distribution by the slit of material bed bottom, whole material bed area reaches 367.2m
2, being difficult to realize uniform gas distribution in whole material aspect, this kind set-up mode is difficult to realize the adaptability to dust content in the flue gas simultaneously, the bed material is difficult to discharge simultaneously.
After flue gas entered distribution device, the dirt of carrying secretly in the flue gas was trapped in the hopper by solid material, and along with the material of hopper effluxes and the discharge system.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
