Abstract
The utility model provides a blowing technical proposal for a grate, mainly comprising a grate frame and a grate on the grate frame. The lower side of the grate is provided with a wind chamber, a wind chamber wall board, and an interval chamber. A blowing tube is communicated with the wind chamber or the interval chamber. The blowing technical proposal for a grate is characterized in that the draught area of an opening on a grate blowing component starts to generally become small from one side of the blowing tube. For example, the draught area of the opening of the grate for the wind chamber, or the draught area of an opening of the wall board, or the draught area of the interval chamber starts to generally become small from one side of the blowing tube. Thus, wind evenly enters the grate, and the combustion efficiency of the grate is improved.
Description
The utility model relates to boiler or kiln fire grate air-supply arrangement, especially traveling-grate stoker balanced ventilation device.
In present technology, to general rectangle air compartment or the fan-shaped air compartment of adopting of fire grate air-supply.It is identical that this air compartment is given the area of fire grate air feed, therefore the problem that has uneven air, although people adopt multiple way in air compartment, as adopt deflector, throttling dividing plate etc. to improve the uneven defective of air distribution, but it is all undesirable, so influenced efficiency of combustion, cause unburned combustible in slag higher, the coal waste.
The purpose of this utility model is exactly the deficiency that exists at existing, and the scheme of a kind of fire grate with the balanced ventilation device is provided.This scheme makes the different air quantity of air compartment diverse location configuration to the fire grate air-supply, makes the suffered blast of fire grate be tending towards balanced, makes the air quantity that enters fire grate equal substantially, thereby preferably resolves the problem of air compartment to the fire grate uneven air.
This programme is achieved by the following scheme.This device comprises the fire grate on fire-grating frame and the fire-grating frame, air compartment is arranged below fire grate, there is compartment one or both sides at the air compartment wallboard, form by ajutage etc., it is characterized in that the opening draught area on fire grate air-supply member, begun to diminish gradually by ajutage one side, concrete scheme has following three:
(1), this device mainly includes the fire grate on fire-grating frame and the fire-grating frame, the air compartment of oriented fire grate air-supply below fire grate, there are ajutage and air compartment to connect, it is characterized in that having at least in the air compartment air compartment of a tilting dividing plate formation, this air compartment is begun by diminishing greatly gradually by ajutage one side the opening draught area of fire grate;
(2), this device mainly includes the fire grate on fire-grating frame and the fire-grating frame, air compartment is arranged below fire grate, this air compartment is identical to the air supply areas of fire grate, the compartment that sealing is arranged in the one or both sides of air compartment, compartment and ajutage are connected, it is characterized in that having an opening at least on the wallboard between air compartment and the compartment, the draught area of this opening is begun by diminishing greatly gradually by ajutage one side.Opening on the described wallboard also can be an aperture area begins many openings of being made up of a plurality of separate openings that diminish gradually greatly by ajutage one side.The air compartment of wind under fire grate by this opening enters fire grate again.
(3), this device mainly includes the fire grate on fire-grating frame and the fire-grating frame, air compartment is arranged below fire grate, this air compartment is that groove is same to the air supply areas of fire grate, stopping up one or both sides at wind has the interval of sealing to stop up, compartment and ajutage are connected, and have an opening that area is identical at least on the wallboard between compartment and the air compartment, and described opening also can be many openings that a plurality of independent air ports are formed, the draught area that it is characterized in that compartment begins by diminishing greatly gradually from ajutage one side.Wind by this compartment on wallboard etc. the opening of draught area, enter the air compartment under the fire grate, enter fire grate again.
More than three technical schemes can merge enforcement because of the fire grate width, also can independently implement a scheme.Constituting the tilting dividing plate that does not wait draught area air compartment or compartment, can be linear, broken line shape, curved dividing plate.
According to the narration of above scheme as can be known, three schemes all are based on a conception plans, and this design promptly utilizes the draught area that diminishes gradually by greatly, forces to the grate surface balanced ventilation.The first string is an air compartment to be become by diminishing greatly gradually the opening ventilating surface of fire grate; The draught area that second scheme is the upper shed of air compartment wallboard is by diminishing greatly gradually; The 3rd scheme is that the opening on the air compartment wallboard is the uiform section opening, and the draught area of the compartment that links to each other of opening is made by diminishing greatly gradually therewith.Above scheme can both make the coal seam air distribution on the fire grate more even, improves efficiency of combustion, reduces the phosphorus content of slag, improves the utilization rate of coal.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
For clearly demonstrating the characteristics of this programme, below by being used for chain fire-gate three specific embodiments, and in conjunction with the accompanying drawings, scheme is set forth.
The embodiment of the first string.
Description of drawings:
