Description
Technical field
The utility model relates to a kind of coal-fired plant boiler coal supply technology, particularly relates to a kind of layer and section blanking type run coal bin of available gas fluidisation.
Background technology
Fire coal in thermal powerplant coal yard is transported in coal bunker and is deposited by coal conveyer belts, then after grinding, enters boiler combustion by falling to feeder and coal mill.Wherein, coal bunker is the equipment that secondary is deposited raw coal, and the reliability of its work and safety directly have influence on the overall process of boiler coal feeding.
The coal bunker of existing thermal powerplant is mostly designed to the conical steel body structure standing upside down, and top is wide, bottom is narrow, is convenient to the whereabouts of raw coal.But the phenomenons such as due to the sticky stickiness of raw coal, slot place, coal bunker bottom is easily stopped up, caking, serious even cause spontaneous combustion.At present, coal bunker inside installs liner plate additional, coal bunker loosening technology (loosening machine, air bubble etc.) is widely used as the means that solve after stopping up, but but can not fundamentally prevent the generation of coal bunker chute blockage.
The obstruction of coal bunker is mainly caused by two reasons, and the one, raw coal deadweight causes the extruding between coal cinder, makes loose particle be compacted into bulk closely, and the 2nd, the moisture in raw coal impels between coal cinder sticky glutinous mutually, is attached on coal bunker inwall, is difficult for falling.
For solving blockage problem, must set about from the weight of raw coal and aqueous ingredients two aspects, need to develop one both can disperse weight, played again the coal bunker of certain desiccation.
Summary of the invention
The utility model provides a kind of layering blanking type fluidisation run coal bin according to the deficiencies in the prior art, this coal bunker hierarchical design, enters coal in the mode of descending stage by stage coal, and the load-bearing of coal bunker bottom is alleviated greatly, in design flow oxidizing gases air port, coal bunker bottom, raw coal in hopper is carried out to fluidized drying simultaneously.
The technical scheme that the utility model provides is: described a kind of layering blanking type fluidisation run coal bin, formed by the storehouse cylinder on top and the discharge bucket of bottom, in the cylinder of storehouse, be separated into multilayer separate space from top to bottom by multiple insertion plate doors, the discharging opening of the inlet point of described discharge bucket and storehouse cylinder is tightly connected, also be provided with insertion plate door at discharge bucket and cylinder junction, storehouse, the electrically-powered actuator of each insertion plate door is arranged on cylinder outside, storehouse, offers multiple fluidisation nozzles for being connected with nitrogen gas cylinder on discharge bucket.
The further technical scheme of the utility model: described insertion plate door has 3-5 layer, is separated into multiple equidistant separate spaces by storehouse cylinder, and wherein an insertion plate door is bottom located at discharge bucket and cylinder junction, storehouse.
The utility model is technical scheme preferably: described insertion plate door is made up of rectangle plate or half arc-shaped insert plate of two docking, two plates insert from the both sides of storehouse cylinder respectively, control end at each plate is equipped with electrically-powered actuator, and two plates are opened respectively or docking closure under the control of its electrically-powered actuator.
The utility model is technical scheme preferably: described storehouse cylinder is cylindric, and described discharge bucket is back taper hopper, and its semi-cone angle is 15 degree～30 degree, the upper communication port of discharge bucket and the equal diameters of storehouse cylinder.
The utility model is technical scheme preferably: described multiple fluidisation nozzles circularize and are distributed on discharge bucket.
Electrically-powered actuator in the utility model is that one can provide straight-line actuating device, and it utilizes certain drive energy and works under certain control signal effect.Actuating unit uses liquid, gas, electric power or other energy and converts it into driving effect by motor, cylinder or other device.
The utility model is divided into multilayer by coal bunker from top to bottom by insertion plate door, cause raw coal segmentation warehouse entry, utilize insertion plate door isolation, raw coal in the hopper of bottom falls into feeder at first, raw coal is replaced blanking from bottom to up successively to orlop hopper, alleviate the weight of raw coal in coal bunker hopper, avoided raw coal to compress caking; In hopper, realize raw coal fluidisation, and there is certain dry effect, effectively prevented the obstruction of raw coal at feed opening, obviously improved the safety and reliability of blanking simultaneously.
Raw coal layered blanking in the utility model, disperse weight, and the raw coal caking that is difficult for being crushed to death, and coal breakage is fluidized, it is sticky glutinous to be difficult for after dry, make the obstruction that is difficult for hardening of raw coal in hopper, avoids coal bunker blocking, ensured carrying out smoothly of blanking.
