Abstract
The invention discloses a hot-eddy combustion-supporting structure, comprising a primary combustion-supporting wind inlet tube, a sucked smoke gas inlet tube, and a suction chamber, wherein the primary combustion-supporting wind inlet tube and the sucked smoke gas inlet tube are received in the suction chamber; the gas outlet end of the suction chamber is of a reducing conical tube structure; and a mixing tube is connected to the top of the conical structure. Via the structure, an eddy can be formed in the vicinity of the outlet of the conical tube of the suction chamber, and a negative pressure condition is formed via the driving of the eddy for a gas in the suction chamber, thus enhancing a negative pressure effect; and a hot smoke gas in a furnace can enter into the suction chamber under the action of a pressure difference, and then is subjected to mixing and heat exchange with primary combustion-supporting wind at the conical outlet, thus re-utilizing the inherent heat of the gas during circulated combustion while increasing the temperature of the combustion-supporting wind and decreasing the excess coefficient of the combustion-supporting wind.
Description
Technical field
The manufacturing equipment field, the especially combustion system that the present invention relates to a kind of ceramic building ornament materials are burnt till the new equipment structure of utilizing hot eddy current combustion supporting technology realization circulating combustion.
Background technology
At present, country requires increasingly highly to energy-conservation, and market competition also grows in intensity, and each incorporated business also is the work of more and more paying attention to energy-conservation this piece.Also need a kind of mode of utilizing the combustion-supporting reduction of waste heat recovery to burn till energy consumption in the ceramic industry.
Summary of the invention
The technical problem that the present invention solved is, provides a kind of can and being mixed in a combustion air low-temperature flue gas recovery in the stove to form mixed type secondary combustion air, realizes the new equipment structure of circulating combustion.
The technological means that the present invention adopted is: the combustion-supporting structure of a kind of hot eddy current; It comprises combustion air blast pipe, by smoking gas blast pipe, suction chamber; This combustion air blast pipe and be placed within the suction chamber by smoking gas blast pipe; The suction chamber outlet side is the conical pipe structure of convergent, and the top of pyramidal structure connects mixing tube.
This combustion air blast pipe is positioned in the middle of the suction chamber, and the top of suction chamber conical pipe structure is aimed in its outlet side.
The conical pipe structure that this combustion air blast pipe front end is a convergent.
This combustion air blast pipe caliber is between the 30-50mm.
One time the combustion air blast pipe connects the combustion air house steward; Connected exhaust gases passes by smoking gas blast pipe; Mixing tube connects the combustion air interface of burner.
The suction chamber cross-sectional area should be long-pending bigger 1 ~ 2 times with suction flue gas blast pipe sectional area sum than a combustion air tube section.
The invention has the beneficial effects as follows: the structure of combustion air blast pipe and suction chamber; Make the suction chamber conical pipe can form eddy current near exporting; This eddy current drives the gas in the suction chamber and forms condition of negative pressure; Strengthened the negative pressure effect, make in the stove hot flue gas can be under the effect of pressure reduction the entering suction chamber, and then mix with a combustion air at conical outlet place, heat exchange; When having improved combustion air temperature, reduction combustion air coefficient of excess, the heat that gas carries is utilized in circulating combustion once more.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the combustion air interface syndeton sketch map of the present invention and combustion air house steward and exhaust gases passes and burner.
The specific embodiment
Like Fig. 1 and shown in Figure 2; The combustion-supporting structure of a kind of hot eddy current of the present invention; It comprises combustion air blast pipe 1, by smoking gas blast pipe 2, suction chamber 3; This combustion air blast pipe 1 and be placed within the suction chamber 3 by smoking gas blast pipe 2, suction chamber 3 outlet sides are the conical pipe structure of convergent, the top 31 of pyramidal structure connects mixing tubes 4.General, one time combustion air blast pipe 1 connects combustion air house steward 5; Connected exhaust gases passes (not marking among the figure) by smoking gas blast pipe 2; Mixing tube 4 connects the combustion air interface (not marking among the figure) of burner.When the combustion air blast pipe 1 of combustion air warp with certain pressure sprays with certain speed; Owing to spray combustion air the gas in the suction chamber 3 is produced drainage; And the flue gas of suction chamber 3 taken away, indoor formation condition of negative pressure, inner flue gas of the stove is through being inhaled into by smoking gas blast pipe 2.Combustion air and inner flue gas of the stove mix in mixing tube 4 and carry out energy exchange, and the speed of a combustion air reduces, and is increased by the speed of smoking gas.Near mixing tube 4 outlets, the two speed convergence balance.
Wherein, this combustion air blast pipe 1 is positioned in the middle of the suction chamber 3, and the top 31 of suction chamber 3 conical pipe structures is aimed in its outlet side.The conical pipe structure that this combustion air blast pipe 1 front end also is a convergent.The conical pipe structure of combustion air blast pipe and suction chamber; Make conical pipe can form eddy current near exporting, this eddy current drives the gas in the suction chamber and forms condition of negative pressure, has strengthened the negative pressure effect; Make in the stove hot flue gas can be under the effect of pressure reduction the entering suction chamber; And then mix with a combustion air at conical outlet place, heat exchange, improved the combustion air temperature, when reducing the combustion air coefficient of excess, the heat that gas carries is utilized in circulating combustion once more.
For utilizing hot eddy-current technique to produce negative pressure more fully, one time combustion air blast pipe 1 more carefully can increase the negative pressure in the suction chamber 3 more, and negative pressure can suck hot flue gas in the kiln more greatly more, is mixed into the secondary combustion air, and is more energy-conservation.But also need consider the amount of squeezing into of combustion air in the actual production, reach optimum state for each burner is burnt till, institute's calorific requirement in guaranteeing to produce, once combustion-supporting airduct 1 caliber is optimum between the 30-50mm.
Be to guarantee the suction chamber negative pressuren zone, suction chamber 3 cross-sectional area than combustion-supporting airduct 1 sectional area once with to suck flue gas blast pipe 2 sectional area sums big.But for guaranteeing to produce bigger negative pressure; The cross-sectional area of suction chamber 3 can not be long-pending more a lot of greatly with suction flue gas blast pipe sectional area sum than a combustion air tube section; And a combustion air blast pipe is to aim at gradual shrinkage pipe middle; The mixed secondary combustion air of ability more efficient use is combustion-supporting, so comprehensively these 3 considerations, it doubly is best that the suction chamber cross-sectional area should amass with sucking the big 1-2 of flue gas blast pipe sectional area sum than a combustion air tube section.
Below be that one group of embodiment respectively manages data.
One time combustion air blast pipe 1 is long 400 millimeters, and external diameter 42.5mm, internal diameter are the pipe of 38.5mm.
Be long 200mm by smoking gas blast pipe 2, external diameter is that 42.5mm, internal diameter are the pipe of 38.5mm.
Suction chamber 3 leading portions are external diameter 140mm, internal diameter 135mm, the cylindric space of long 150mm.
Suction chamber 3 back segments are conical pipe, import external diameter 140mm, internal diameter 135mm.Outlet external diameter 55mm, internal diameter 50mm, the gradual shrinkage conical pipe of long 60mm.
Mixing tube 4 is 55mm for external diameter, and internal diameter is 50mm, the pipe of long 150mm.
