Abstract
The utility model provides a prevent stifled device suitable for wet flue gas desulfurization powder is carried, is including whitewashed storehouse, thick liquid jar, the hot -blast main road pipeline of fluidization, push -pull valve, batcher, its characterized in that: the thick liquid jar on be provided with drain, the hot -blast trunk line of fluidization and batcher lower extreme connecting line between be provided with the hot -blast branch pipe way of fluidization. Be particularly useful for lime stone / lime the desulfurizer powder prevents the stifled system that prevents blockked up dissolving the in -process in gypsum wet process, magnesium method and the two alkaline process desulfurization.
Description
Technical field
This utility model belongs to environmental technology field, more particularly relates to a kind of suitable for the anti-of wet desulphurization powder conveying
Block apparatus.
Background technology
At present, in wet desulphurization green technology route, limestone/lime-gypsum method, magnesium processes and Dual alkali mainly take off
Sulfur technique, desulfurizing agent selected by desulfurization is solid powder form, and powder conveying also more adopts Pneumatic ash conveying mode, desulfurizing agent powder
Last Jing Pneumatic ash conveyings are temporarily stored into powder powder cabin, when desulphurization system equipment puts into operation to be needed, desulfurizer powder Jing powder cabin bottom hoppers,
Push-pull valve, batcher and enter serum pot with serum pot connecting line, and be prepared into after desulfurizing agent solution with aqueous solution should
For flue gas desulfurization.To increase desulfurizing agent solution and heat smoke reactivity or speed, generally require that desulfuration solution is carried out to add
Heat treatment or desulfurizing agent course of dissolution itself release heat, and during blanking, desulfurizing agent is blended moisture in system and enters powder
Enter powder hopper, cause powder agglomatess plug to block up, so as to cause the failure of conveying equipment, and then have influence on the failure of whole system.
For many years, it is to solve defeated grey powder blanking blockage problem, common technology means have vibration or beat inwall, rotation scrapes
Cut the methods such as inwall, gas injection inwall, hopper rotation.Although the stifled problem of powder blanking plug can be alleviated to a certain extent,
But above-mentioned technical proposal fails fundamentally to solve agglomeration problems of making moist in blanking process.It is also frequent in practical engineering application
Generation powder blanking is made moist and fills in stifled phenomenon.
The content of the invention
For disadvantages described above, this utility model provides a kind of anti-block apparatus suitable for the conveying of wet desulphurization powder, especially
Desulfurizer powder prevents what is blocked in course of dissolution suitable for limestone/lime-gypsum wet method, magnesium processes and double alkali method desulfurizing
Anti-blocking system.
The technical solution of the utility model is：A kind of anti-block apparatus suitable for the conveying of wet desulphurization powder, including powder cabin,
Serum pot, fluidisation hot blast main road pipeline, push-pull valve, batcher；Described powder cabin by connecting line successively with push-pull valve, feed
Machine, serum pot are connected, and described fluidisation hot blast main road pipeline is connected with powder cabin, and emptying is provided with described serum pot
Mouthful；Fluidisation hot blast bypass line is provided between described fluidisation hot blast main road pipeline and batcher lower end connecting line.
Further, a kind of anti-block apparatus suitable for the conveying of wet desulphurization powder, on described fluidisation hot blast manifold road
It is provided with control valve.
Further, a kind of anti-block apparatus suitable for the conveying of wet desulphurization powder, described fluidisation hot blast manifold road with
One end of connecting line connection is downward-sloping pipeline.
Beneficial effects of the present invention：One is to give full play to fluidized wind effect, on the basis of heating fluidized wind moisture-proof dosing technology, no
Need the big equipment of additional to be capable of achieving Dampproof stopper to block up, save labour and cost；Two is to make full use of serum pot top drain
With fluidized wind main line, blocked up by setting up the i.e. achievable powder conveying system Dampproof stopper of fluidized wind branch road, valve, side simple to operate
Just；Three is to prevent steam from entering powder blanking hopper and pipeline from source with angle diagonally downward, has thoroughly prevented blanking and has made moist
The stifled problem of caking plug；Four is volatilization steam outer row in time, reduces moisture condensation deposition or absorbs corrosion of the erosion to equipment.
Description of the drawings
Fig. 1 is a kind of generalized section of the anti-blocking system suitable for the conveying of wet desulphurization powder of this utility model.
Wherein 1 serum pot, 2 drains, 3 batchers, 4 push-pull valves, 5 powder cabins, 6 control valves, 7 fluidisation hot blast manifolds
Road, 8 fluidisation hot blast main pipe roads.
Specific embodiment
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
A kind of anti-block apparatus suitable for the conveying of wet desulphurization powder, including powder cabin 5, serum pot 1, fluidisation hot blast main road pipe
Road 8, push-pull valve 4, batcher 3；Described powder cabin 5 is connected successively by connecting line with push-pull valve 4, batcher 3, serum pot 1
Logical, described fluidisation hot blast main road pipeline 8 is connected with powder cabin 5, and drain 2 is provided with described serum pot；Described stream
Change and fluidisation hot blast bypass line 7 is provided between hot blast main road pipeline 8 and the lower end connecting line of batcher 3；Described fluidisation heat
Control valve 6 is provided with wind bypass line 7；One end that described fluidisation hot blast bypass line is connected with connecting line is to dip down
Oblique pipeline.
Originally the operating process of anti-blocking induction system is：When desulphurization system equipment puts into operation to be needed, fluidized wind bypass duct is opened
Road 7 controls valve 6, keeps heating fluidized wind bypass line 7 to be in circulation status, the bottom hopper of desulfurizer powder Jing powder cabins 5, plate
Valve 4 and the blanking of batcher 3, desulfurizing agent starts to mix into serum pot 1 and aqueous solution, and part moisture is heated in stirring mixed process
Volatilization produces steam, volatilizees under the fluidized wind of fluidisation hot blast bypass line 7 effect on batcher 3 and the connecting line of serum pot 1
Steam is made moist the stifled possibility of caking plug by the top drain 2 of serum pot 1 outer row in time so as to prevent powder.
The flanged fitting adopted in this programme is generic connectivity part with valve, can be threaded connection according to requirement of engineering
Can connect for welded seal, but valve prioritizing selection thread seal connected mode, facilitate valve body device damage or failure to dismantle more
Change.
After said structure, the anti-blocking induction system of this programme is opened when needed or the holding of desulphurization system running status
Normally open.
