Abstract

The utility model discloses a fluidized bed cloth wind system all, include: parallelly connected two bellows locating the furnace both sides, two bellows through a header pipe to two bellows air supplies, a plurality of tuber pipes that keep the clearance of welding form the air distribution passageway between two bellows, two bellows are right the tuber pipe air supply, each a plurality of tube heads of equipartition on the tuber pipe, and each the tube head upper shield is equipped with a hood in order to form the wind bed one time. The utility model discloses to present cloth wind system defect all, the design adopts neotype cloth wind system all, has sufficient clearance between tuber pipe facial make -up air distribution cap, tuber pipe and tuber pipe, and convenient great cubic sediment falls from between the tuber pipe when falling the sediment, can guarantee the even of combustion chamber air distribution like this, can guarantee the smooth and easy of sediment again, also has certain cooling action to the lime -ash simultaneously.

Description

A kind of fluid bed cloth wind system

Technical field

The utility model relates to the cloth wind structure of fluidized-bed combustion boiler, more particularly, is a kind of fluid bed cloth wind system.

Background technology

When world's energy shortage, except the oil fuel of costliness and the coal fuel that is commonly used, each country is actively encouraging to use biomass fuel and garbage fuel, as the mud of mud, paper plant, the vinasse, municipal refuse etc. of Alcohol Plant.These fuel are nonflammable, the solid matter that also can produce a large amount of lime-ash after burning simultaneously and cannot burn, as stone, iron sheet, aluminium pot, glass, the plumbous stone of coal etc., very easily arrange for air distribution plate air distribution and make troubles, lime-ash, stone and glass etc. secondly after burning also can cause cloth wind locking plug.

Traditional fluid bed many employings air distribution plate, bellows and large-scale bell-type windshield composition cloth wind system, shown in Figure 1, the slag that falls of this combustion system carries out falling slag by the slag dropping tube be arranged on air distribution plate, stone etc. relatively large in fuel can be in operation and be stuck between blast cap, affects slag and burning.

Utility model content

Because prior art also exists the problems referred to above, the utility model proposes a kind of fluid bed cloth wind system, it effectively can solve problems of the prior art.

The utility model solves the problem by the following technical programs:

A kind of fluid bed cloth wind system, comprise: two bellows of burner hearth both sides are located in parallel connection, described two bellows are blown to described two bellows by a header pipe, the airduct welding some maintenance gaps between described two bellows forms air distribution passage, described two bellows are to described air duct blow, uniform some tube heads on airduct described in each, and tube head described in each is covered with a blast cap to form First air bed.

The vertical section of described air distribution passage forms a V-type bed by the adjustment high and low position of each airduct and/or the shape of airduct.

The vertical section of described air distribution passage forms a U-shaped bed by the adjustment high and low position of each airduct and/or the shape of airduct.

Described airduct is heat-resisting thick-walled structure.

Described airduct model is Φ 89mmx8mm.

Described tube head is Φ 36mmx4mm.

The utility model is for the defect of existing cloth wind system, design adopts novel cloth wind system, airduct assembles blast cap, between airduct and airduct, has enough gaps, when falling slag, convenient larger block slag falls between airduct, the even of combustion chamber air distribution can be ensured like this, can ensure the smooth and easy of slag again, certain cooling effect be also had to lime-ash simultaneously.This novel cloth wind system we claim DF to arrange, dissolve the adverse consequences that the design of traditional cloth wind produces fully, it be not necessary for remove on air distribution plate remain fail the solid of burning and shutdown maintenance, the equipment such as especially outstanding advantage is applicable to the fuel containing a large amount of stones, glass, scum etc., minimizing slag cooler that simultaneously can be suitable.

Accompanying drawing explanation

Fig. 1 is traditional cloth wind system, and lime-ash is discharged from slag dropping tube, and relatively large lime-ash easily blocks the space between blast cap, causes cloth wind uneven.

Detailed description of the invention

Below in conjunction with detailed description of the invention, describe the utility model in detail.

Shown in Fig. 2-Fig. 3 C, Fig. 2 is fluid bed cloth wind system partial schematic diagram of the present utility model, leaves enough gaps between airduct, is convenient to relatively large lime-ash and discharges.Fig. 3 A-Fig. 3 C is fluid bed cloth wind system structural representation of the present utility model.

Fluid bed cloth wind system of the present utility model, comprising: two bellows 1 and 2 of burner hearth both sides are located in parallel connection, and described two bellows 1 and 2 are blown to described two bellows 1 and 2 by a header pipe 3.The airduct 41 welding the heat-resisting heavy wall in some maintenance gaps between described two bellows 1 and 2 forms air distribution passage 4, described two bellows are blown to described airduct 41, airduct model is Φ 89mmx8mm, the tube head 5 of uniform some Φ 36mmx4mm on airduct described in each, and tube head described in each is covered with a blast cap 6 to form First air bed.Owing to maintaining larger gap between airduct, when using larger coal cinder or rubbish, cinder faster can be drained by the gap between airduct, overcoming air distribution plate and to blow the problem of the burner hearth deslagging difficulty brought, ensureing the stability of burning.

Be V-type bed cloth wind system of the present utility model see Fig. 4 A-Fig. 4 C, Fig. 4 A-Fig. 4 C.The vertical section of described air distribution passage forms a V-type bed by the adjustment high and low position of each airduct and/or the shape of airduct.V-type bed cloth wind system is comparatively applicable to coal-burning boiler.

Be U-shaped bed cloth wind system of the present utility model see Fig. 5 A-Fig. 5 C, Fig. 5 A-Fig. 5 C.The vertical section of described air distribution passage forms a U-shaped bed by the adjustment high and low position of each airduct and/or the shape of airduct.U-shaped bed cloth wind system is comparatively applicable to biomass boiler, and configures with this Secondary Air being applicable to burning, the Secondary Air from overfire air fan is sent into burner hearth, reaches perfect effect.

Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
