Description
Technical field
The present invention relates to a kind of kitchen range, especially relate to a kind of premixed alloy fiber kitchen range.
Background technology
The burning of combustion gas all needs air-breathing, and the mixed proportion of combustion gas and air and mixability have determined the burning degree of combustion gas.When mixed proportion the best and the mixability of air and combustion gas is the best constantly, fuel gas buring is the most abundant, burns also the most fully, and the calorific value that produces is also the highest, and the waste gas and the pernicious gas that produce after the burning are also minimum, thereby reach the purpose of efficient, energy-conservation and environmental protection.All kinds of commercial kitchen ranges in the market generally adopt two kinds of empty combustion mixed combustion modes of nature injection type and blowing-type.These two kinds of combustion modes all are rear mixing burnings, be that combustion gas is in the burner hearth internal combustion, mix with air, can't guarantee fully mixing of combustion gas and air, this must cause the part combustion gas to fail fully to burn namely to discharge from flue, and the thermal efficiency is lower and flame temperature is lower, has wasted mass energy, and carbon monoxide and nitrogen oxide content are all higher in the not clean-burning combustion gas, therefore also air have been caused certain pollution.
Summary of the invention
The purpose of this invention is to provide a kind of premixed alloy fiber kitchen range, combustion gas and air can fully be mixed, improve the efficiency of combustion of combustion gas, reduce the discharging of pernicious gas, to realize energy-conserving and environment-protective.
For addressing the above problem, the technical solution used in the present invention is:
A kind of premixed alloy fiber kitchen range comprises shell body, is arranged on the interior air inlet pipe of shell body and the burner plate of inner chamber cylinder and shell body top loose structure; Described inner chamber cylinder bottom opening, its top is provided with base; Described air inlet pipe bottom is fixed on the shell body bottom, its top connects the mixed aerofoil of turbine, the mixed aerofoil of described air inlet pipe and turbine stretches in the inner chamber bucket, and the mixed aerofoil edge of turbine is fixed on the inwall of inner chamber cylinder, has on the mixed aerofoil of turbine and runs through its skewed slot up and down more than one; Be provided with air distribution plate between described burner plate and the base, have the aperture that supplied gas is passed through on the described air distribution plate; The mixed aerofoil of described inner chamber cylinder inwall, air inlet pipe and turbine forms interior mixed chamber, and inner chamber drum outer wall, shell body and air distribution plate form outer mixed chamber.Combustion gas and air are realized mixing for the first time in interior mixed chamber, then mist enters into outer mixed chamber, carrying out the second time by the porous metals air distribution plate time mixes, well-mixed gas is in the fully burning of burner plate surface, greatly improved the efficiency of combustion of combustion gas, carbon monoxide and nitrogen oxide content also reduce thereupon in the flue gas after the burning, have reached the effect of energy-saving and emission-reduction.
As a further improvement on the present invention, described cavity is the gradual change type structure, and two ends are cylindric about it, and the centre is round table-like, and the upper end body diameter is less than the diameter of lower end cylinder.Lower end diameter has improved the admission velocity of combustion gas greater than the gradual change type structural cavity body of upper end diameter, be convenient to combustion gas and mix in interior mixed chamber with air.
As a further improvement on the present invention, described skewed slot is evenly distributed on the mixed aerofoil of turbine.Skewed slot is evenly distributed with and is beneficial to gas and enters behind the outer mixed chamber more evenly, and unlikely local pressure is excessive or too small.
As a further improvement on the present invention, described skewed slot has 12.12 skewed slots are so that air and combustion gas are mixed to get more abundant in the first time.
As a further improvement on the present invention, described shell body is made of two parts up and down, and its upper end is cylindric, and the lower end is round table-like.Up big and down small shell body is fit to the design arrangement of internal structure, and has reduced the space that whole kitchen range takies.
As a further improvement on the present invention, described cavity bottom is provided with internal thread.Cavity bottom arranges internal thread and is threaded connection with gas pipeline, and is not only easy for installation, and good sealing effect, air tight.
Further improve as of the present invention, described burner plate top is provided with flange plate, and described flange plate and burner plate are bolted outside case top.Not only good sealing effect is air tight with flange plate fixed combustion version, and burner plate is stressed even, not yielding everywhere, long service life.
In sum, the invention has the beneficial effects as follows: combustion gas and air mix, and the combustion rate of combustion gas is high, and noxious gas emission is few, and pollution on the environment is few.
