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 are the best constantly, fuel gas buring is the most abundant, burns also the most completely, and the calorific value producing is also the highest, and the waste gas and the pernicious gas that produce after burning are also minimum, thereby reach the object 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 are all rear mixing burnings, be that combustion gas is in stove chamber inner combustion, mix with air, cannot ensure fully mixing of combustion gas and air, this must cause part combustion gas to fail fully to burn and from flue, discharge, and the thermal efficiency is lower and flame temperature is lower, has wasted mass energy, and in not clean-burning combustion gas, carbon monoxide and nitrogen oxide content are all higher, therefore also air have been caused to certain pollution.
Summary of the invention
The object 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 discharge 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 air inlet pipe in 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 shell body bottom, its top connects the mixed aerofoil of turbine, the mixed aerofoil of described air inlet pipe and turbine stretches in inner chamber cylinder, and the mixed aerofoil of turbine edge is fixed on the inwall of inner chamber cylinder, has one and run through above its upper and lower skewed slot on the mixed aerofoil of turbine; Between described burner plate and base, be provided with air distribution plate, on described air distribution plate, have the aperture that supplied gas is passed through; 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 for the first time and being mixed in interior mixed chamber, then mist enters into outer mixed chamber, when by porous metals air distribution plate, mix for the second time, well-mixed gas is in the fully burning of burner plate surface, greatly improve the efficiency of combustion of combustion gas, in flue gas after burning, carbon monoxide and nitrogen oxide content also reduce thereupon, have reached the effect of energy-saving and emission-reduction.
As a further improvement on the present invention, described air inlet pipe is gradual change type structure, and its upper and lower two ends are cylindric, and centre is round table-like, and upper end body diameter is less than the diameter of lower end cylinder.The gradual change type structure air inlet pipe that lower end diameter is greater than upper end diameter has improved the admission velocity of combustion gas, is convenient to combustion gas and mixes 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 uniformly distributed and is conducive to gas and enters behind 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 make air and combustion gas be mixed to get more abundant for the first time.
As a further improvement on the present invention, described shell body is made up of upper and lower two parts, and its upper end is cylindric, and lower end is round table-like.Up big and down small shell body is applicable 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 air inlet pipe bottom is provided with internal thread.Air inlet pipe bottom arranges internal thread and is threaded connection with gas pipeline, 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 case top outside.With flange plate fixed combustion plate, not only good sealing effect is air tight, and burner plate is stressed even, not yielding everywhere, long service life.
In sum, the invention has the beneficial effects as follows: combustion gas mixes with air, the combustion rate of combustion gas is high, and noxious gas emission is few, and pollution on the environment is few.
