Description

A kind of New-type boiler oil ignition device

Technical field

The utility model relates to a kind of oil ignition device, and particularly a kind of New-type boiler oil ignition device belongs to the boiler plant technical field.

Background technology

At present, boiler plant starts or is transferred in the higher load running by utmost point underload bringing into operation, generally be to realize to the mode that burner hearth sprays heavy oil by the annex of special use, though it is simple that this method of operation has equipment, advantage easy to use, still, required heavy oil quantity is bigger, heavy oil combustion is insufficient, so the cost of operation is higher, simultaneously, because heavy oil combustion is insufficient, not only produce serious waste, simultaneously, environment also caused seriously influence, in addition, also there is the slower scarce limit of response speed in this method of operation.

The utility model content

The purpose of this utility model is: a kind of New-type boiler oil ignition device is provided, this igniter has with oil mass economic, the operation response speed is fast, the sufficient advantage of fuel oil, it is higher to overcome the existing boiler plant existing operating cost that is in operation, environmental pollution is serious, the slower scarce limit of operation response speed.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: a kind of New-type boiler oil ignition device, and it is made up of fuel reserve tank, oil pump, air compressor, air accumulator, air-flow stop valve, oil combustion gun, oily flow shutoff valve, spray chamber, ultrasonic transducer, oil strainer, materail tube way, secondary air cover, primary zone, secondary wind inleting tube, secondary combustion chamber, protecting tube; Igniter has an air compressor, with between air compressor, air accumulator, the air-flow stop valve with pipeline be linked in sequence the back link to each other with the air inlet of oil combustion gun; After fuel reserve tank, oil pump, oil strainer, spray chamber, oily flow shutoff valve be linked in sequence with pipeline, link to each other with the oil-in of oil combustion gun; The transmitting terminal and the spray chamber of ultrasonic transducer are linked together; The primary zone is installed in the right oral area of material pipe middle part inwards, protecting tube communicates with the inside of primary zone from the outside of material pipe, oil combustion gun inserts in the primary zone from protecting tube, secondary combustion chamber is installed in material pipe right output port position, and being do not seal open between secondary combustion chamber and the material pipe is connected, the coaxial line of secondary air cover is installed in the right-hand member of material pipe, it partly covers secondary combustion chamber inside, and secondary wind inleting tube is communicated with secondary air cover inside.

Operation principle of the present utility model is: oil pump is extracted the oil in the fuel reserve tank out, and after filtering, oil strainer is sent to spray chamber, ultrasonic transducer is dither under the driving of ultrasonic output circuit, because transducer and spray chamber are the fixed structures of one, so, the fluid of spray chamber is also done the vibration of high frequency ground, under the ultrasonic wave effect, clustering area fluid molecule is broken up separation mutually, thereby forms mist of oil, because when high-speed compressed air stream penetrates from oil combustion gun, can form negative pressure at oil combustion gun ground oil-in, so the mist of oil in the spray chamber just enters the oil-in of oil combustion gun through oily flow shutoff valve, and, from oil combustion gun, spray with after compressed air mixes.After entering the one-level combustion chamber by the gas mixture of oil combustion gun ejection, the piezoelectric ceramic electric fire maker light in the one-level combustion chamber gas mixture, oil combustion gun is constantly imported gas mixture, just constantly keeps fired state in the one-level combustion chamber.By the material pipe input is coal dust and air ground mixture, after coal dust arrives secondary combustion chamber, the air that is incorporated in the secondary air cover with secondary wind inleting tube mixes, under ejection ground, one-level combustion chamber flame ignition, the coal dust that is in the two stage burner is lighted, material pipe is constantly imported coal dust, then just constantly keeps fired state in two stage burner.

Beneficial effect: a kind of New-type boiler oil ignition device of the present utility model, use light fuel as combustion adjuvant, can reach the degree of few oil or little oil on oil mass, have with oil mass economic, the operation response speed is very fast, the sufficient advantage of fuel oil, and it is higher to overcome the existing boiler plant existing operating cost that is in operation, environmental pollution is serious, the slower scarce limit of operation response speed.
