Abstract
A kind of non-pressure air compartment, including chamber and is arranged in the air inlet of chamber side, and the bluff body of chamber interior is arranged in；The bluff body include hollow shell and set on shell close to the airflow orifice of described air inlet one end and the baffle of the other end set on the shell；The airflow orifice is arranged to opening towards the air inlet, and the baffle is configured to the relatively described shell activity, to open or close the hollow enclosure interior airflow channel.Bluff body and shell are wedge shape, and wedge-shaped front end microcephaly faces air inlet.Airflow orifice size is determined according to bluff body through-current capacity.The present invention has many advantages, such as flexible modulation air compartment pressure everywhere, realizes non-pressure distribution.
Description
Technical field
The present invention relates to a kind of non-pressure air compartments, are used for fluidized combustion equipment air distribution, belong to energy machinery apparatus field.
Background technique
Fluidized combustion equipment, such as fluidized bed, often requiring setting in fuel progress heat treatment process includes
Blowing system including air compartment.These air compartments are all usually isobaric air compartment.And in the processing of the specific fuels such as waste, often need
Good treatment effect is realized by non-isobaric air distribution, and often due to service condition variation needs corresponding adjusting burner hearth
Base pressure.To solve this problem, often the different air compartment of several wind pressure is arranged in burner hearth bottom in prior art means, as in
State's patent " a kind of combustion apparatus with cross-section variable circulating fluidized bed " (CN1305074A) is proposed.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is non- press air compartment, can be each in flexible modulation air compartment according to specific needs
Locate pressure.
The present invention is achieved through the following technical solutions:
A kind of non-pressure air compartment, including chamber and the air inlet that chamber side is arranged in, it is characterised in that: the air compartment is also
Bluff body including chamber interior is arranged in；The bluff body includes hollow shell and is set to the shell close to the air inlet
The baffle of the airflow orifice of one end and the other end set on the shell；The airflow orifice is arranged to opening towards the air inlet
Mouthful, the baffle is configured to the relatively described shell activity, to open or close the hollow enclosure interior air-flow
Channel.
In above-mentioned technical proposal, the bluff body is Wedge passive, and the front end microcephaly of the bluff body faces the air inlet.
In above-mentioned technical proposal, the shell is wedge-shaped shell, and the front end microcephaly of the shell faces the air inlet
In above-mentioned technical proposal, the airflow orifice size is calculated according to bluff body through-current capacity and is determined.
In above-mentioned technical proposal, before being with the air inlet, after the chamber other side is, the baffle is with the wedge shape
Horizontal plane where casing centerline is axial plane fore-aft travel.
The present invention has the following advantages and beneficial effects: the setting of Wedge passive makes different zones forming curves in air compartment
The distribution of shape pressure；Baffle opening size and direction adjust the shapes and sizes distribution of pressure curve, to meet particular needs
It wants.
Detailed description of the invention
Fig. 1, which is that one kind according to the present invention is non-, presses air compartment schematic diagram.
Fig. 2 is the non-Wedge passive structural schematic diagram for pressing air compartment of one kind according to the present invention.
In figure: 1- chamber；2- air distribution plate；3- air inlet；4- bluff body；5- blast cap；6- burner hearth；7- slag-drip opening；
8- airflow orifice；9- baffle；10- shell.
Specific embodiment
A specific embodiment of the invention and the course of work are further described with reference to the accompanying drawing.
The positional terms such as the upper, lower, left, right, front and rear in present specification be positional relationship based on the figure and
It establishes.Attached drawing is different, then corresponding positional relationship is also possible to change therewith, therefore cannot be interpreted as with this to protection model
The restriction enclosed.
A kind of non-pressure air compartment, including chamber 1 and the air inlet 3 that 1 side of chamber is arranged in.Embodiment as shown in Figure 1
In, the bottom of the burner hearth 6 of fluidized combustion equipment is arranged in the air compartment.The part wall that chamber 1 connects with burner hearth 6 is as cloth
Aerofoil 2 is provided with blast cap 5 by certain rotation direction requirement on air distribution plate 2.Blast cap 5 is usually wind cap.The lowest side of air distribution plate 2
It is provided with slag-drip opening 7.In the processing such as specific fuel of rubbish or other wastes, needed to form in burner hearth specific eddy flow or
Turbulent flow, 5 cloth wind wind pressure of blast cap is different at this time.Therefore, the air compartment further includes the bluff body 4 being arranged in inside chamber 1；The bluff body
4 be wedge structure, and the nosed microcephaly of the bluff body 4 faces the air inlet 3, and the front and back of bluff body 4 to center line with
It is parallel to enter the wind direction.
It is formed as shown in Fig. 2, bluff body 4 is surround by hollow shell 10, shell 10 is wedge shape, and surface is smooth streamlined.
Before being using the air inlet 3,1 other side of the chamber be after as front and back to nosed microcephaly's face of the shell 10
The air inlet 3, the front end of the shell 10 offer airflow orifice 8, airflow orifice 8 calculates true according to 4 through-current capacity size of bluff body
It is fixed.The tail portion of wedge-shaped shell 10 is provided with baffle 9.Using horizontal plane where 10 center line of the wedge-shaped shell, as axial plane, baffle 9 can
Around axial plane fore-aft travel.When baffle 9 closes, i.e., when baffle 9 is uprightly arranged, the fluidizing agent fed from air inlet 3 is with wedge
Shape bluff body 4 is barrier detour, does not have fluid transit inside Wedge passive 4.Bluff body 4 is by the pressure highest point in chamber 1 at this time
For above 1 front end of chamber, i.e., close to 3 one upper side of air inlet.And when without bluff body, pressure highest point is separate in chamber 1 in chamber 1
3 side of air inlet.The aperture regulation of baffle 9 wind pressure high point position.The active level of baffle 9 according to pressure regulation curve setting, with
Meet pressure needs.
When chamber 1 is connected with combustion apparatus, and air distribution plate 2 is provided with blast cap 5 above chamber 1, the structure of blast cap 5 is big
It is small at the same play a part of adjust pressure.The baffle 9 of bluff body 4 is cooperated to adjust, it is easier to which also more flexible realization pressure, which is adjusted, needs
It asks, and does not need replacement blast cap 5 and configure.
