Abstract

The utility model relates to a flame jet type lighter which is suitable for lighting combustion nozzles using gas and liquid fuel, particularly for lighting industrial furnaces. The utility model can simultaneously enter gas and air that are mixed and sprayed out from a combustion nozzle. When the mixed combustible gas which is sprayed flows across a lighter head and meets the electric sparks produced by the lighter head, the mixed combustible gas is lit immediately. The utility model which can also utilize a probe rod and a monitor to observe the ignition condition has the advantages of compact structure, automatic mixing ratio adjustment, inflammable ignition, no interference from outside airflow, simple operation and good safety.

Description

Flame injecting type igniter

The utility model relates to a kind of igniter, especially a kind of flame injecting type igniter that is applicable to the Industrial Stoves igniting.

At present, Industrial Stoves are when going into operation igniting, and employing is piled fire or lighted a fire from the mode that stove gate stretches into burner with torch usually.This mode needs manual operations, and often igniting is very difficult.In recent years, some adopts spark ignition.Put fire gas merely with electric spark, be not easy to light, this is because the ignition temperature of coal gas is higher, and air and coal gas must just can be lighted after reaching certain mixing ratio.Therefore when igniting, should send into coal gas, also need send into an amount of air simultaneously, this brings certain inconvenience to operation, if the operation mismate not only is difficult for lighting, and easily causes the accident.Aspect a thermal monitoring, all adopt the ultraviolet fulgurite to measure the burner duty at present.Whether because some spark parts are contained in the burner shell or burner block is inner, the flame of burned flame and spark ignition is ultraviolet ray again, therefore easily causes to obscure and slip up, can not demonstrate burner exactly and be lighted when lighting a fire.

The purpose of this utility model provides a kind of flame injecting type igniter, and it can not only regulate the mixing ratio concentration of air and coal gas automatically, and fuel is lighted easily, and can accurately monitor out the ignition conditions of combustion gas by the ion monitoring device.

Concrete scheme of the present utility model is: comprise igniter head, igniting chamber, combustion barrel, its structural feature is: A. has spray cone in the igniting chamber that is positioned at igniter head front, spray-hole is arranged on the spray cone, the heavy caliber end of spray cone is connected with connector, mixture pipe is installed on connector, mixture pipe is connected with air inlet pipe, and air hose and gas pipe are arranged on air inlet pipe; B. in the passage that connector, igniting chamber and combustion barrel constitute, have a detector bar to insert, one of this detector bar inserts in the burner, and one is connected with monitor through lead, and indicator lamp is arranged on monitor.

Combustion barrel of the present utility model is inserted on the burner of Industrial Stoves, enter with air hose at air, after coal gas entered air inlet pipe from gas pipe, air and coal gas mixed the formation fuel gas by a certain percentage.Gaseous mixture enters spray cone through mixture pipe and connector, then from the spray-hole ejection, when the mixed combustible gas body of ejection is flowed through igniter head, run into the electric spark that igniter head produces, at once mist is lighted, and sprayed to combustion barrel, soon coal gas is lighted in the kiln.Whether gaseous mixture is lighted can directly be observed by detector bar and monitor.Detector bar is transmitted in the ion monitoring device by cation in the flame and free electron.After monitor is connected power supply, the indicator lamp of the monitor light that is white in color, after mixed gas was by spark ignition, cation in the flame and free electron were transmitted in the monitor by the detection rod, and indicator lamp white light breath goes out, and presents red light.

Adopt such scheme, compact conformation, air and coal gas can enter simultaneously, and its mixing ratio can be regulated automatically, and it is inflammable to light a fire, and is not subjected to extraneous interference in air flow, simple to operate, safe and reliable, and the igniting situation can show automatically.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is overall structure figure of the present utility model, also is an embodiment of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

In Fig. 1, the utility model is made up of air hose 1, gas pipe 2, air inlet pipe 3, mixture pipe 12, detector bar 4, monitor 5, connector 7, igniter head 8, combustion barrel 9, igniting chamber 10, spray cone 11.Its annexation is: igniter head 8 is installed on 10 tube walls of igniting chamber, and combustion barrel 9 is installed in the tail end in igniting chamber 10, in the igniting chamber 10 that is positioned at igniter head 8 fronts spray cone 11 is arranged, and spray-hole 13 (as shown in Figure 2) is arranged on the spray cone 11.The heavy caliber end of spray cone 11 is connected with connector 7, and mixture pipe 12 is installed on connector 7, and mixture pipe 12 is connected with air inlet pipe 3, and air hose 1 and gas pipe 2 are arranged on air inlet pipe 3.In the passage that connector 7, igniting chamber 10 and combustion barrel 9 constitute, there is a detector bar 4 to insert, 4 one of this detector bars insert in the combustion barrel 9, and one is connected with monitor 5 through lead, and indicator lamp 6 is arranged on monitor 5.
