Abstract
The utility model discloses a novel overgrate air is assisted to living beings hot -blast furnace device, include that air -supply line, the vertical guide duct of overgrate air, overgrate air are violently managed, the exhaust vent. 4 the welding of root overgrate air vertical guide duct is in furnace inner wall four corners, its top connect 4 each other communicating horizontal overgrate air violently manage, evenly arrange the exhaust vent on each tuber pipe, the utility model has the advantages that: firstly, the three -dimensional air feed of multi -direction multi -angle in furnace is equipped to this overgrate air, strengthens the interior disturbance that mixes the air field of furnace, makes flue gas and fuel volatility and overgrate air mix more evenly. Secondly, increase the area of contact of unsatisfactory position of these combustion efficiencies of each angle of furnace and air for it is more abundant to burn.
Description
Technical field
The utility model relates to a kind of small-sized biomass hot-blast stove secondary blowing device, the most important thing is three-dimensional secondary air device.Belong to boiler technology field.
Background technology
Nowadays China is to the research of the hot-blast stove of biomass molding fuel all still in the stage of fumbling, is only transform with experience.Because biomass molding fuel volatile matter is high, the broad-minded reason of burning requisite oxygen, cause burning insufficient when actual motion, waste fuel, and then make the efficiency of boiler low, cannot provide convenient cost-effectively to normal production, thus provide sufficient amount of oxygen in combustion to hot-blast stove, become people's urgent problem.But existing hot-blast stove is only pass into First air below fire grate, this is far from being enough, so be necessary for the design and development of auxiliary Secondary Air construction and device.
Hot-blast stove mostly small-sized at present just passes into air for the utilization of secondary air supply device above burner hearth, so just makes fuel only better in side ratio of combustion, not only does not play combustion-supporting effect like this, and burning is degenerated.
Summary of the invention
The object of the present invention is to provide the three-dimensional multidirectional Secondary Air air supply device of a kind of novel biomass hot-blast stove, solve that the burning of small-sized biomass hot-blast stove heating surface is insufficient, amount of oxygen is not enough, drip the problem of tar over-emitting black exhaust.Technical problem to be solved is exactly by arranging the position of secondary air channel and the angle of exhaust vent thereof, allowing fuel fully contact with Secondary Air, reach desirable combustion efficiency.
In order to solve the problems of the technologies described above, present invention employs following technical scheme.
Novel biomass hot-blast stove secondary air device of the present invention, comprises blast pipe, the vertical guide duct of Secondary Air, Secondary Air transverse tube, exhaust vent.4 vertical guide ducts of Secondary Air are welded on inboard wall of burner hearth corner, pipe are evenly arranged 10 exhaust vents, and exhaust vent axially becomes miter angle with airduct axis; Above 4 vertical guide ducts, connect 4 Secondary Air transverse tubes communicated with each other, horizontal welding is connected on inboard wall of burner hearth surrounding (being all connected with transverse tube above the vertical guide duct of every root), pipe is evenly arranged 16 exhaust vents, and exhaust vent axially all points to burner hearth center.
The utility model has the advantages that: one be this Secondary Air be equipped in existing hot-blast stove basis on increase air output, in burner hearth, the three-dimensional air feed of multi-direction multi-angle, makes flue gas mix with Secondary Air more even.Two is the contacts area increasing the undesirable position of these combustion efficiencies of each angle of burner hearth and air, makes burning more abundant.
accompanying drawing illustrates:
Fig. 1: a kind of secondary blowing apparatus structure schematic diagram.
Fig. 2: a kind of wind direction schematic diagram of secondary blowing device.
Fig. 3: a kind of top view of secondary blowing device.
In figure: 1 blast pipe, the vertical guide duct of 2 Secondary Air, 3 Secondary Air transverse tubes, 4 exhaust vents, 5 furnace walls, 6 Secondary Air wind directions.
detailed description of the invention:
With reference to accompanying drawing, in conjunction with detailed description of the invention, the invention will be further described.
As depicted in figs. 1 and 2, a kind of novel biomass hot-blast stove secondary air device of the present utility model, comprises 1 blast pipe, the vertical guide duct of 2 Secondary Air, 3 Secondary Air transverse tubes, 4 exhaust vents, 5 furnace walls, 6 Secondary Air wind directions.
When this device normally runs, blast pipe is connected on air blast, and Secondary Air is by the vertical guide duct of burner hearth corner, lead in the Secondary Air transverse tube of four levels again, air from the angled blowout of the exhaust vent of each airduct, thus makes air and fuel and flue gas Homogeneous phase mixing, strengthens burning.
