Background technology
Existing Pen Dong – fluid bed obtains common attention and the significant progress of spouted bed researcher and fluid bed researcher due to the advantage with spouted bed and fluid bed.This Pen Dong – fluid bed, compared with the spouted bed of routine, not only can promote the heat transfer between fluid and particle, mass transfer, can also effectively prevent from occurring dead band and the reunion of easy bonded particulate in annular space district bottom annular space district.But also Shortcomings part: maintain gas flow ratio needed for this Pen Dong – fluid bed separately spouted and needed for independent fluidisation throughput want large, 1. add certain bypass air feed auxiliary equipment simultaneously.2. the media particle in traditional spouted bed has significantly inside and outside laminar flow feature, and bed endoparticle lacks lateral/radial mixing, makes the surface of partial particulate fail acquisition and makes full use of, produce adverse influence to heat and mass in bed.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is, provides a kind of spraying-fluidized bed monoblock type multiinjector structure, improves while realizing spraying-fluidized bed particle and fluid two-phase flow process intensification technology.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A spraying-fluidized bed monoblock type multiinjector structure, comprises spouted bed main body, and spouted bed body end is provided with inlet jet, and described inlet jet only has one, is linked together between inlet jet and spouted bed body end by flow guide sleeve;
Described spouted bed body end is divided into straight length and Taper Pipe section, and Taper Pipe section is near inlet jet;
Described flow guide sleeve is divided into water conservancy diversion straight length and deflection cone pipeline section, and the end of water conservancy diversion straight length is cemented on straight length;
Straight length and the Taper Pipe Duan Shangjun of described spouted bed body end are processed with multiple sidewall hole, the gas part entered from inlet jet directly enters in spouted bed main body, and the gas another part entered from inlet jet enters in spouted bed main body along flow guide sleeve from sidewall hole.
The utility model also has distinguishes technical characteristic as follows:
The shape of described sidewall hole is circular hole, and the diameter of circular hole is greater than the diameter of fluidized particle, and the diameter of circular hole is less than the internal diameter of inlet jet.
Annular space distance between the inwall of described water conservancy diversion straight length and the outer wall of straight length is 0.5 ~ 1 times of the internal diameter of inlet jet.
The length of described water conservancy diversion straight length is 1.1 times of the length of deflection cone pipeline section.
The tapering of described deflection cone pipeline section is 40 ° ~ 65 °, and the tapering of described Taper Pipe section equals the tapering of deflection cone pipeline section.
Compared with prior art, useful technique effect is the utility model:
Together with the bypass nozzle being used for particle fluidization is processed with main burner global design by the utility model, share same gas feed, gas inlet zone has been extended to the sidewall in spouted bed annular space district simultaneously, sidewall has the hole of some, 2 improvement of spouted bed particle, fluid two-phase mixtures process intensification can be realized like this.
Achieve the fluidization of spouted bed circular cone inclined-plane place particle, eliminate flow dead, bypass air feed equipment and associated pipe can be saved relative to the dynamic – fluidized-bed structure of spray simultaneously.
Compare and traditional spouted bed structure, hole place on annular space district sidewall has air-flow to inject, produce horizontal gas jet, thus realize the endocorpuscular fluidization in spouted bed annular space district, strengthen mixing of spouted bed annular space district endoparticle and inlet zone gas, spouted bed annular space district can be realized mix with the lateral/radial of gas in inlet zone and particle, thus the momentum of strengthening annular space district endoparticle and gas jet, heat and mass transfer process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, the implication of each label is: the spouted bed main body of 1-, 2-inlet jet, 3-flow guide sleeve, 4-sidewall hole; (1-1)-straight length, (1-2)-Taper Pipe section, (3-1)-water conservancy diversion straight length, (3-2)-deflection cone pipeline section.
Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
Detailed description of the invention
Defer to technique scheme, below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.Below in conjunction with embodiment, the utility model is described in further details.
Embodiment 1:
Defer to technique scheme, as shown in Figure 1, the present embodiment provides a kind of spraying-fluidized bed monoblock type multiinjector structure, comprise spouted bed main body 1, spouted bed main body 1 end is provided with inlet jet 2, described inlet jet 2 only has one, is linked together between inlet jet 2 and spouted bed main body 1 end by flow guide sleeve 3;
