The above prior art solutions have the following drawbacks: when the oil mist is ignited, the oxygen content around the oil mist is insufficient, so that the oil mist is not combusted sufficiently, energy is wasted, and toxic substances are generated.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the ignition device of the combustor, which has the advantages of improving the combustion fullness of oil mist so as to achieve the effects of energy conservation and environmental protection.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides an ignition of combustor, includes nozzle, oil pipe, connects glib talker and interior tuber pipe in oil pipe one end, interior tuber pipe cover establish oil pipe outside and with oil pipe between form interior wind chamber, be equipped with first air intake on the interior tuber pipe, interior tuber pipe is established to the air-out end towards the one end of glib talker, the air-out end of glib talker and interior tuber pipe is connected simultaneously on the nozzle, be equipped with the spout on the nozzle.

Through the technical scheme, during ignition, oil is conveyed to the oil nozzle from the oil pipe and is dispersed into oil mist, meanwhile, air enters the inner air cavity from the first air inlet and is conveyed to the oil nozzle to be mixed with the oil mist and is sprayed out from the nozzle of the nozzle, so that the oxygen content of the surrounding environment of the oil mist during combustion is improved, the combustion filling degree of the oil mist is further improved, and the effects of energy conservation and environmental protection are achieved.

The invention is further configured to: and a mixing chamber is also arranged between the nozzle and the oil nozzle, and two ends of the mixing chamber are respectively connected with the nozzle and the inner air pipe in a clamping manner.

Through above-mentioned technical scheme, the air that the air-out end of interior tuber pipe is bloated and nozzle tip spun oil mist can be from the nozzle blowout and the burning again after the intensive mixing in the mixing chamber to improve the mixture degree of consistency between oil mist and the air, and then improve the area of contact between oil mist and the air, when burning like this, the oil mist can be more abundant by the burning, more energy-concerving and environment-protective.

The invention is further configured to: the inner air pipe is sleeved with an outer air pipe, a second air inlet is formed in the outer air pipe, an outer air cavity is formed between the outer air pipe and the inner air pipe, and air flow enters the outer air cavity from the second air inlet and is sprayed out along the periphery of the nozzle.

Through the technical scheme, when the mixed oil mist is sprayed out of the nozzle, the airflow in the outer air pipe is sprayed out of the periphery of the nozzle, and the oxygen content at the periphery of the oil mist is further improved by the airflow, so that the oil mist can be combusted fully.

The invention is further configured to: and a plurality of air injection holes are formed in the periphery of one end, close to the nozzle, of the outer air pipe, and the air injection holes are communicated with the outer air cavity.

Through above-mentioned technical scheme, a plurality of fumarole sets up along the periphery of nozzle, and when the fumarole blowout was followed to the air current in the tuber pipe in addition, can distribute at the oil mist periphery and form the brattice to play a collection effect to the oil mist, with the loss that reduces the oil mist, and can be abundant with the oil mist contact, with the combustion efficiency who improves the oil mist.
