Description

The electronic ignition altar lamp

Technical field:

The utility model relates to a kind of novel electron igniter.Be specifically related to a kind of electronic ignition altar lamp.Mainly be applicable to the automatic control system of various petrochemical heating furnace burners.The burner that also can be used for other Industrial Boiler that automatic control needs are arranged, marine boiler, heat-conducting oil furnace, hot-blast stove etc.

Background technology:

Original electronic ignition device is seen Fig. 1～2.Mainly form by central point firelock 4, stable flame cover 2, jet awl 3, mixing tube 5, joint 6, fuel gas pipe 7, ignition 8, stop valve, magnetic valve and switch board etc.The heavy caliber end lower end of jet awl 3 is connected with mixing tube 5, and the upper end is connected with stable flame cover 2, and mixing tube 5 is connected with joint 6, and joint links to each other with fuel gas pipe 7.Central point firelock 4 is plugged on the center of stable flame cover 2, jet awl 3 and mixing tube 5, is made up of metallic rod central electrode 4-1, ceramic inner sleeve 4-2, metal tube external electrode 4-3 and contact electrode 4-4.The flat successively from inside to outside muzzle of inner sleeve and metal tube external electrode is contained on the central electrode, and the central electrode rear end links to each other with contact electrode 4-4, and contact electrode links to each other with ignition 8.Its basic functional principle is: the fuel gas in the pipe network is directly sent in the electronic ignition device mixing tube by stop valve, magnetic valve, mix with air, switch board is given high-energy electronic igniter with the voltage of AC220V, ignition is given the central point firelock by high-tension cable with the high pressure of 2400V, the central point firelock produces electric spark in limited range, should light the fuel gas (its condition is that the pressure of fuel gas can not surpass 0.01MPa) through mixing under the normal condition in the igniter exit.

Because the central point firelock only produces electric spark between metallic rod central electrode and metal tube external electrode, its ignition direction is parallel with the airflow direction of fuel gas, and fuel gas is that the periphery from the metal tube external electrode flows away.When fuel air pressure is higher than 0.01MPa, during especially up to 0.03MPa, because gas flow rate is very fast, the possibility that electric spark and fuel gas are collided is very little, and igniter is difficult to light.In fact, gas pressure is high more, and ignition point is far away more from the igniter outlet.When pressure during up to 0.03MPa, its ignition point has 150～230mm from the igniter outlet, this moment more difficult electricity consumption spark ignition fuel gas.

Therefore the basic reason of existing electronic ignition device cisco unity malfunction is that electric spark and fuel gas can not be collided effectively.Even the pressure of fuel gas is higher, the possibility of lighting is also very little.

Summary of the invention:

The electronic ignition altar lamp that provides a kind of electric spark and fuel gas to collide effectively is provided the purpose of this utility model.

Technology contents of the present utility model is: a kind of electronic ignition altar lamp, comprise the central point firelock, stable flame cover, jet awl, mixing tube, joint and ignition, the heavy caliber end lower end of jet awl is connected with mixing tube, the upper end is connected with stable flame cover, the mixing tube lower end is connected with joint, the central point firelock is plugged on stable flame cover, the center of jet awl and mixing tube, comprise central electrode, inner sleeve, outer tube and contact electrode, the central electrode rear end links to each other with contact electrode, contact electrode links to each other with ignition, be characterized in that inner sleeve and outer tube are sleeved on the central electrode back segment from A-P mismatch successively from inside to outside, are equipped with the inner conical gland on the stable flame cover internal face.Fuel gas in the pipe network enters in the mixing tube, mix with air, ignition is given the central point firelock with high pressure, its airflow direction of getting angry direction and fuel gas of central point firelock intersects, electric spark and fuel gas can be collided effectively, even fuel gas pressure is higher, the also very easy fire fuel of igniter.Therefore the utility model ignition success rate height, can adapt to high-pressure fuel gas.

The specific embodiment:

As Fig. 3～4, electronic ignition altar lamp of the present utility model mainly is made up of central point firelock 4, stable flame cover 2, inner conical gland 1, jet awl 3, mixing tube 5, joint 6 and ignition 7 etc.On the jet awl 3 awl walls fumarole 3-1 is arranged, the heavy caliber end lower end of jet awl 3 is connected with mixing tube 5, and the upper end is connected with stable flame cover 2.Mixing tube 5 lower ends are connected with joint 6, and joint 6 links to each other with fuel gas pipe 8.Fuel gas pipe 8 links to each other with metal hose (pipe network), on the inner conical gland 1 awl wall fumarole 1-1 is arranged, and inner conical gland 1 revolves to be put in stable flame cover 2 upper inside wall.Central point firelock 4 is plugged on the center of stable flame cover 2, inner conical gland 1, jet awl 3 and mixing tube 5.As Fig. 5, central point firelock 4 is made up of metallic rod central electrode 4-1, ceramic double-layer mismatch inner sleeve 4-2, metal jacket pipe 4-3, contact electrode (copper sleeve) 4-4 and insulating base 4-5.Inner sleeve 4-2 and metal jacket pipe 4-3 from inside to outside from front to back successively mismatch be sleeved on metallic rod central electrode 4-1 back segment, inner sleeve 4-2 is double-deck mismatch structure.Insulating base 4-5 is placed on central electrode 4-1 bottom, and inner sleeve 4-2 and outer tube 4-3 lower end are inserted on the insulating base 4-5.The front end of metallic rod central electrode 4-1 is processed into the wedge shape plush copper, and exposes stable flame cover 2 ends top, and the rear end is connected with contact electrode 4-4.Contact electrode 4-4 links to each other with ignition 7.

As Fig. 6, Fig. 6 is for adopting burner automatic control system schematic diagram of the present utility model.On the fuel gas pipe 8 successively device gas gauge 9, igniter solenoid valve 10, pressure regulator valve 11, pressure-reducing valve 12, pneumatic filter 13 and switch board 14 etc. are arranged.According to operating the different of requirement and bleed pressure, system can suitably delete.When system during, can omit parts such as igniter solenoid valve and switch board only with manual mode of operation; When bleed pressure is lower than 0.05Mpa, can omit pressure regulator valve and pressure-reducing valve; When only operating and bleed pressure when being lower than 0.05Mpa, can omit igniter solenoid valve, switch board, pressure regulator valve and pressure-reducing valve simultaneously with manual mode.

No matter the utility model is at ignition principle, product structure, and still aspect fuel gas pressure adaptation ability and product cost, all more original autoelectrinic igniter is significantly improved and improves.Test of many times result shows, when the novel electron igniter is 0.02Mpa at the pressure of fuel gas, can be repeatedly operate as normal repeatedly.Newly, old electronic ignition device cost contrasts as following table:

Sequence number	Project	Newly	Old	Remarks
						1	Ignition transformer	300	3000	Old ignition transformer volume is big, and output voltage is low and cost is high.
2	High-tension cable	Do not have	1000	The long high-tension cable of 4m easily flattens and inconvenience is fixed.
					3	Burning torch	1000	1000	New sparking plug quality guarantees easily
4	The combustion gas pre-treatment	1700	Do not have	Increase pre-treatment, can adapt to different ductwork pressures.
					5	Add up to	3000	5000

Therefore the novel electron igniter is not only simple in structure, ignition success rate is high, can adapt to high-pressure fuel gas, also has cheap characteristics.
