At present, one of processing method that purifying smoke commonly uses is adsorbent method, and the device being generally adopted is gas-solid injector.By air conveying mode, in sorbent injection to the flue gas of flowing, adsorbent will be made to carry out with harmful substance contacting and adsorbing to come its elimination, and eventually through cleaner, they are removed, reach the purpose of purifying smoke.
Tradition gas-solid injector basic structure mainly has hopper, nozzle, receiving chamber, hybrid chamber, diffusion chamber and transfer pipeline.After the compression air of certain pressure level flows through gradual shrinkage nozzle, form high-speed jet.The gas receiving indoor is produced entrainment and carry by this jet in the process advanced, thus forming certain negative pressure.Material enters receiving chamber under the effect of pressure reduction and gravity, and carries lower entrance hybrid chamber in entrainmenting of gas jet.In hybrid chamber, the further mix homogeneously of gas-particle two-phase, with after through diffusion chamber supercharging enter transfer pipeline.
But the feature that traditional gas-solid injector is fixed due to its structure, when actual pressed powder emitted dose changes, jet expansion cannot be carried out corresponding adjustment to the distance of hybrid chamber entrance, there is the problem that material transfer efficiency is low, affects the varying duty performance of gas-solid injector.Further, since when solid and gas amount changes, material holdup time in receiving chamber, respective change also occurred, it is likely that cause the blocking of ejector, influential system stable operation, how when varying duty, Quick dredging gas-solid injector is also a problem needing to solve.
Summary of the invention
Technical problem:The present invention seeks to for above-mentioned prior art, it is provided that a kind of simple in construction, it is possible to the convenient jet expansion distance to hybrid chamber entrance that regulates, the problem that solution tradition gas-solid injector transfer efficiency when meeting change is low；Below receiving chamber, set up dump skip, it is possible to discharged from ejector by the material being trapped in receiving chamber in time, solve the conveying blockage problem because material lagging produces.
Technical scheme:
A kind of adjustable gas-solid injector, including the housing with receiving chamber, hybrid chamber, diffusion chamber and transfer pipeline, it is additionally provided with charging aperture, discharging opening and air inlet on the housing, described charging aperture and discharging opening are positioned at described receiving chamber, described air inlet is positioned at described receiving chamber front end and connects with the nozzle being arranged on housing, it is characterized in that: what described nozzle slided is arranged in described housing, be provided with one in the bottom of described nozzle for being automatically adjusted described nozzle elastic device of the spacing S of jet expansion and hybrid chamber entrance under gas pressure effect.
Described elastic device includes adjusting knob, spring dead plate and spring, described spring dead plate is positioned at described housing, described adjusting knob one end is placed in described hull outside, the adjusting knob other end is connected with described spring dead plate and is used for the position adjusting described spring dead plate in described housing, and described spring is arranged between spring dead plate and nozzle bottom.
Being provided with two sealing surfaces between described housing and nozzle, these two sealing surfaces are positioned at the both sides of described air inlet.
The rotary pocket feeder driven by frequency conversion motor it is connected at described charging aperture.
It is connected to ball valve at described discharging opening, is connected to compressed air inlet pipe at described air inlet.
Immediately below described receiving chamber, dump skip is installed, at described receiving chamber material inlet and dump skip on the same axis.
Described afterbody adjusting knob can axially control the jet expansion initial length to hybrid chamber entrance distance S, then passes through the compressed-air actuated pressure of control, utilizes pressure reduction and spring that S value carries out follow-up micro-be automatically adjusted.
Beneficial effect:
(1) the adjustable gas-solid injector of the present invention, in hull outside, adjusting knob is set, it is connected by female thread with housing, the difference according to material, displacement and fed distance, by rotating tail knob, the distance S of jet expansion to hybrid chamber entrance is carried out initial adjustment；In enclosure interior, movable mechanism 15 is set, namely at A, B two sealing surface, it is respectively symmetrically in cavity between nozzle front portion appendix and housing and arranges two and be fixed on appendix and axially slidable bead, by controlling compressed-air actuated pressure, utilize pressure reduction that S value carries out follow-up micro-be automatically adjusted.Owing to jet is after nozzle sprays, under various drag effect, speed can be gradually lowered, and static pressure gradually rises.Therefore the increase of S value, can cause that in receiving chamber, stress level raises, and is unfavorable for the material entrance from hopper, reduce the efficiency of ejector.If reduce S value simultaneously, although stress level in receiving chamber can be made to reduce, but the ambient atmos suction volume entering induction system from material inlet can be increased, jet does not only exist the balanced of velocity field with ambient atmos, there is also the balancing procedure of pressure field simultaneously, therefore material energy expenditure is compared bigger, the same efficiency reducing ejector.So there is an optimum in S.The present invention is by the coordinated of mechanism described above, it is possible under different materials, displacement and fed distance, finds best S value, improves the efficiency of gas-solid injector.
(2) the adjustable gas-solid injector of the present invention, arranges dump skip on the same axis of material inlet below receiving chamber, dump skip ball valve mounted below, is conducive to being detained the discharge of material, it is ensured that the smooth and easy operation of ejector, saves cost.
(3) the adjustable gas-solid injector of the present invention, arranges frequency control rotary pocket feeder at material inlet, it is possible to according to actual needs, changes the flow of material in time.
(4) the adjustable gas-solid injector of the present invention, simple in construction, easy to operate, production cost is low.
