Description
Technical field
The utility model relates to the circulating technology such as biological substance for combustion, rubbish field, especially a kind of fluidized-bed combustion boiler air-distribution device.
Background technology
CFBB is efficient, the oligosaprobic combustion technology developed rapidly nearly decades.It has close to or reaches the efficiency of combustion of same capacity coal-powder boiler; The fuel tolerance of this combustion technology is strong, not only the fat coals such as bituminous coal can be used, and the various inferior fuel of burning, and the living beings, rubbish, industrial waste etc. except fossil fuel, its low-temperature burning makes NOX growing amount few, available lime masonry sulfur-removing additives, low cost realizes desulfuration in furnace, is one of best clean coal combustion technology of the commercialization degree of generally acknowledging in the world.
In the process of combustion refuse or papermaking waste material, often due to the complexity of its composition, non-combustible material such as such as iron wire, iron block etc. is had to send into burner hearth with feeding system, when adopting fluidized bed combustion mode, larger negative effect can be produced to goods fluid, cause large slag muck to amass, affect normal discharge and the operation of boiler.
In the middle of existing technology, the general inclined distributor that adopts carries out bottom deslagging, carries out classification deslagging to slag charge not in advance, and large slag and thin slag are discharged from same slag-drip opening, easily cause slag-drip opening to block, and deslagging effect is bad.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of deslagging efficiency is high, the air-distribution device of deslagging selective deslagging thoroughly.
The utility model solves the technical scheme that its technical problem adopts: the air-distribution device of selective deslagging, comprise the air distribution plate being arranged on furnace interior, burner hearth is formed above air distribution plate, water cooled wind chamber is provided with in below air distribution plate, burner hearth is formed above air distribution plate, water cooled wind chamber is provided with in below air distribution plate, bottom scum pipe is provided with bottom described air distribution plate, bottom this, scum pipe lower end is run through described water cooled wind chamber and is stretched out body of heater outside, upper end is communicated with burner hearth through air distribution plate, side scum pipe is also provided with in air distribution plate side, this side scum pipe port of export connects cold slag equipment, scum pipe upper end, side is communicated with burner hearth through air distribution plate, region between bottom scum pipe and side scum pipe is provided with the bell-jar wind cap corresponding with side scum pipe, the wind orientation of water cooled wind chamber is delivered to side scum pipe by this bell-jar wind cap, thin slag is delivered to side scum pipe and then discharge by bell-jar wind cap, side scum pipe can reclaim end slag heat simultaneously, improve system effectiveness, bottom scum pipe is used for the slag of the larger end of not easily discharging to discharge burner hearth, improve boiler goods fluid, maintain boiler to run reliably and with long-term.
Described air distribution plate is made up of castable and blast cap, described castable is laid in the top of water cooled wind chamber, described blast cap is through air compartment top and castable, be communicated with water cooled wind chamber, described castable is from undulate structure viewed from C direction, formed two " funnels " or multiple " funnel ", each " funnel " bottom connects bottom scum pipe, and side arranges side scum pipe.
Described water cooled wind chamber is single plenum chamber structure, adopts membrane type structure or heat-insulating structure.
The beneficial effects of the utility model are: the utility model is provided with thin slag floss hole and accesses cold slag equipment at burner hearth rear portion, for the deslagging needs normally run, end slag heat can be reclaimed, improve system effectiveness, thick slag floss hole is provided with at burner hearth bottom, slag of the larger end for will not easily discharge discharges burner hearth, improves boiler goods fluid, maintains boiler and runs reliably and with long-term.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is top view of the present utility model.
Be labeled as in figure: 1-burner hearth, 2-air distribution plate, 3-water cooled wind chamber, scum pipe bottom 4-, 5-side scum pipe, 21-castable, 22-blast cap, 23-bell-jar wind cap.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As Fig. 1, Fig. 2, shown in Fig. 3, the air-distribution device of selective deslagging, comprise the air distribution plate 2 being arranged on furnace interior, burner hearth 1 is formed above air distribution plate 2, water cooled wind chamber 3 is provided with in below air distribution plate 2, bottom scum pipe 4 is provided with bottom described air distribution plate 2, bottom this, scum pipe 4 lower end is run through described water cooled wind chamber 3 and is stretched out body of heater outside, upper end is communicated with burner hearth through air distribution plate, it is characterized in that: be also provided with side scum pipe 5 in air distribution plate 2 side, this side scum pipe 5 port of export connects cold slag equipment, side scum pipe 5 upper end is communicated with burner hearth through air distribution plate, region between bottom scum pipe and side scum pipe is provided with corresponding to side scum pipe bell-jar wind cap 23, the wind orientation of water cooled wind chamber 3 is delivered to side scum pipe bell-jar wind cap and thin slag is delivered to side scum pipe and then discharge by this bell-jar wind cap 23, side scum pipe can reclaim end slag heat simultaneously, improve system effectiveness, bottom scum pipe is used for the slag of the larger end of not easily discharging to discharge burner hearth, improve boiler goods fluid, maintain boiler to run reliably and with long-term.
Described air distribution plate 2 is made up of castable 21 and blast cap 22, described castable 21 is laid in the top of water cooled wind chamber, described blast cap is through air compartment top and castable, be communicated with water cooled wind chamber, described castable, from undulate structure viewed from C direction, is formed two " funnels " or multiple " funnel ", air distribution plate can be divided into multiple section, be conducive to the maximization design needs meeting boiler, each " funnel " bottom connects bottom scum pipe, and side arranges side scum pipe.
Described water cooled wind chamber 3 is single plenum chamber structure, adopts membrane type structure or heat-insulating structure, and structure is simple, and has larger space to carry out the maintenance of the equipment such as air distribution plate, bottom scum pipe.
When boiler normally runs, air enters burner hearth 1 from water cooled wind chamber 3 through bell-type windshield 22, make the goods fluid in burner hearth 1 and circulation, fuel burns in the process of fluidisation and circulation, the high-temperature flue gas produced brings material into upper furnace space, larger particle catches in the cyclone separator be connected with burner hearth 1, and less particle enters flue, and heat-exchange device continues heat exchange to it.Slag at the bottom of bulky grain sends into cold slag equipment by side scum pipe 5, maintains boiler operatiopn bed pressure.Be deposited on slag at the bottom of the larger particle of bottom and discharge burner hearth bottom by bottom scum pipe 4, meet boiler fluidisation needs.
