Description

A kind of contraction type vaporizer

Technical field

The utility model relates to a kind of contraction type gasification installation.

Background technology

Small-sized chain furnace or reciprocal push away raise stove operationally, and the coal that coal bunker is added from feed inlet is moved into stove with fire grate Thorax burns, and is easy to cause coal seam combustion not exclusively, ash content carbon is high.If the calorific value of coal is low, easily there is circuit fire phenomenon；If coal Volatile matter it is high, then the fuel gas that largely evaporates is uncombusted just to be discharged, and is polluted.

With attention of the public to air environmental pollution, the pollution of coal-fired Industrial Boiler, arcola also faces severeer Improvement or close down pressure, therefore cleaning coal utilization technology is more and more paid attention to.Raw coal gasifies before entering hearth combustion Pre-burning is also a kind of mode of coal clean utilization.

Coal gasification is capable of providing clean combustible gas as fuel or raw material, is often considered as the important of coal clean utilization Mode.Currently used gasification furnace form has fixed bed, fluid bed and air flow bed.Moving bed tends to belong to one kind of fixed bed.

And conventional gasification furnace requires the characteristics such as the ash fusion point of coal, moisture, granularity；Generally need standby heat source；Slightly It is high containing tar, benzene and phenol etc., exhaust gas, cost for wastewater treatment in coal gas；Producing the process of coal gas, there are security risk.

Utility model content

The utility model is in view of the above shortcomings of the prior art, there is provided a kind of contraction type vaporizer, for coal or other Solid fuel gasification.

The utility model is achieved by the following technical solution：

A kind of contraction type vaporizer, including housing, the feed inlet for being arranged on housing upper end, bell, the outlet of gasification gas, comb shape Wall and the bottom fire grate for being arranged on housing bottom；The housing central section and lower part are additionally provided with gasification air hose, steam pipe arrangement and inspection Look into door；The enclosure interior gradually tapers up into inverted trapezoidal mesa-shaped from top to lower part；The bell is up-narrow and down-wide bucking ladder Shape, housing upper is stretched into from housing tip, is arranged on below feed inlet；The steam pipe arrangement is arranged on housing central section, positioned at material Below clock；Case width increase is in corner regions below the steam pipe arrangement；The comb shape wall is in tilted layout in lower housing portion side, Form slag stream and gasification gas passage；The gasification gas outlet is arranged on going out for the comb shape wall slag stream formed and the gas passage that gasifies Mouth side.

More than 2 partitions are arranged at intervals on the comb shape wall and form comb form passage.

In above-mentioned technical proposal, the partition is rectangle or up-side down triangle or inverted trapezoidal or inverted steps shape.The comb shape Wall is 0 ~ 45 ° with horizontal direction angle β

In above-mentioned technical proposal, the bell can be as toward the wind-distributing pipe that gasifying agent is passed through in housing.

Compared with prior art, the beneficial effects of the utility model are：The setting of bell, reduce bulky grain solid fuel into The accumulation compacting phenomenon of material process, makes charging evenly；The setting of comb shape wall then while timely discharge gasification gas, delays gas Change residue, the discharge process of carbon residue, extend vaporization time, enhance gasification result.

Embodiment

The concrete structure, operation method and implementation of the utility model are carried out with embodiment below in conjunction with the accompanying drawings detailed Discuss.

The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and Establish.Attached drawing is different, then corresponding position relationship is also possible to change therewith, therefore cannot be interpreted as with this to protecting model The restriction enclosed.

Go out as shown in Figure 1, the utility model includes housing 1, the feed inlet 2 for being arranged on 1 upper end of housing, bell 3, gasification gas Mouth 7, comb shape wall 9 and the fire grate 8 for being arranged on 1 bottom of housing.

Irregular inverted trapezoidal platform is gradually tapered up into inside housing 1 from top to lower part, 1 upper end of housing is wide, and cross section is suitable Vertical direction to gradually taper up, the narrow funnel-form in the wide lower section in upper end is formed on cross section.1 cross-sectional right side inclined plane of housing and water Square to angle α be 45 ° ~ 90 °.Neck passage is formed at funnelform 1 lower part of housing（That is the pan of funnel）, on neck passage Side sets steam pipe arrangement 5, and steam pipe arrangement 5 is located at below bell；Gasification air hose 4 is set below neck passage.Fuel gasification process Required gasification agent steam and air are sent into housing 1 by steam pipe arrangement 5 and gasification air hose 4 respectively.

The bell 3 is up-narrow and down-wide back-off funnel-form, stretches into 1 top of housing from 1 top of housing, is arranged on feed inlet 2 lower sections.Solid fuel enters housing 1 by feed inlet 2, scatters under the material toggling effect of bell 3 to 1 both sides of housing, along material Passage between clock 3 and tapered housing 1 slides downwards, and slowly gasification is contacted with gasifying agent.The arrangement and housing 1 of bell 3 are gradually Contracting is set so that solid fuel is fed evenly, be it also avoid fuel and is directly dropped to form compacting accumulation.

The width increase of side below steam pipe arrangement 5 of housing 1 forms corner regions, by corner regions when gasification gas overflows upwards Barrier, avoids gasification shortness of breath road from directly being discharged from feed inlet 2.

Fire grate 8 is located at the bottom of housing 1, and the bottom of the superjacent air space and the neck passage of housing 1 of fire grate 8 separates.Housing 1 The bottom side of neck passage be in tilted layout comb shape wall 9, the comb shape wall 9 is 0 ~ 45 ° with horizontal direction angle β.Comb shape More than 2 partitions 10 are arranged at intervals on wall 9 and form comb form passage, so as to form slag stream between neck passage and fire grate 8 With gasification gas passage.Comb shape wall 9 forms buffering and the effect combed to slag stream.Partition 10 is rectangle or up-side down triangle or the ladder that falls Shape or inverted steps shape.Residue, carbon residue and the gasification gas produced during fuel gasification enters stove by slag stream and gasification gas passage The superjacent air space of row 8.

Gasification gas outlet 7 is arranged on the outlet side of slag stream and gasification gas passage that the comb shape wall 9 is formed.Gasification gas passes through The gas that gasifies exports 7 and enters follow-up burner burning.Residue, carbon residue after gasification are dropped on the fire grate 8 of 1 bottom of housing, A part of the fire grate 8 as subsequent combustion device, while residue, carbon residue are sent into follow-up burner and burnt.

Inspection door 6 is arranged in the neck passage of housing 1, easy to observe gasify in vaporizer situation and the maintenance of scarfing cinder coke cleaning.

In another embodiment, bell 3 can be as toward the wind-distributing pipe that gasifying agent is passed through in housing 1.
