More for the version of burner in the ignition furnace of SINTERING PRODUCTION, the feature of this burner is the gas port place at burner, air and coal gas beginning premix, outside along nozzle, mixes in space gas exit again.Mixed gas, air all can use.Existing burner mostly adopts the premix carrying out air and coal gas at burner mouth, single mixed form can form coal gas and mix with air uneven, thus cause the temperature distributing disproportionation of nozzle surrounding flow, flame periphery, not only affect the life-span of burner, also can increase the consumption of coal gas.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of two water conservancy diversion burner, and air and coal gas are carried out secondary mixing by this burner, improve efficiency of combustion.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of telescopic pair of water conservancy diversion burner, comprise gas inlet, gas pipe, air intlet, air hose and air nozzle, described gas inlet is oblique to be fixed on gas pipe, air intlet is oblique to be fixed on air duct, described gas pipe is applied in air hose, described air hose one end is connected with air nozzle, also comprise jet for gas, described jet for gas is connected to the end of gas pipe, jet for gas setting corresponding with air nozzle, multiple air guide channel is provided with near gas pipe gas outlet place in the middle part of described jet for gas, described air guide channel is distributed on jet for gas at an angle.
Preferably, the axis of described air guide channel tilts relative to the border line of jet for gas cross section.
Preferably, described air guide channel all tilts to same direction.
Preferably, described air hose and air nozzle, gas pipe and jet for gas are by being welded to connect.
Preferably, be provided with back-up block between described gas pipe and air hose, described back-up block is played a supporting role, and prevents gas pipe from rocking in air hose.
Preferably, be provided with swirl vane between described gas pipe and air hose, described swirl vane is arranged on space gas nozzle top, between gas pipe and air hose.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
The two water conservancy diversion burner of cartridge type of the present utility model, jet for gas is provided with multiple equally distributed inclination air guide channel, air enters in jet for gas by the air guide channel on jet for gas again by air hose and coal gas mixes in advance, air continues through air nozzle ejection air to be continued to mix with coal gas, so repeatedly premix is carried out to coal gas, improve gas combustion efficiency; Air guide channel is what be obliquely installed, and air can change original traffic direction through air guide channel, and the air stroke eddy current effect sprayed with air nozzle, makes coal gas and air fully mix, and improves efficiency of combustion.
