Abstract

The invention, which belongs to the sintering ignition furnace field, discloses a sleeve type dual-guiding burner nozzle comprising a gas inlet, a gas pipe, an air inlet, an air pipe, and an air nozzle. The gas inlet is fixed at the gas pile in a slant mode; the air inlet is fixed at the air pipe in a slant mode; the gas pipe is installed in the air pipe; and the right end of the air pipe is connected with the air nozzle. In addition, the burner nozzle also includes a gas nozzle connected to the end portion of the gas pipe; and the gas nozzle and the air nozzle correspond to each other. A plurality of gas-guide channels are formed at positions, approaching a gas outlet of the gas pipe, of the middle part of the gas nozzle; and the gas-guide channels penetrating the gas nozzle are distributed at the gas nozzle uniformly. According to the invention, the multiple slanted gas-guide channels distributed uniformly are arranged at the gas nozzles. The air at the air nozzle mouth and gas of the gas nozzle at the nozzle center are mixed secondarily, so that the air and the gas can be mixed fully. Therefore, the gas combustion efficiency is improved.

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 technical scheme of the present invention, following beneficial effect can be obtained:
The two water conservancy diversion burner of cartridge type of the present invention, 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.
