Abstract
A tubular heating furnace gas nozzle relates to a gas nozzle, and solves the unsafe status of a low success rate of one-time ignition caused by cooperation of an existing cylindrical straight tube-type gas injection pipe and an electronic ignition gun. The tubular heating furnace gas nozzle is characterized in that a nozzle coil with a trident-shaped nozzle gas-feeding branched pipe is installed at a spout of the cylindrical gas injection pipe; and a plurality of elliptical gas orifices are arranged on the inner side of the nozzle coil, which makes gas eddies jet out, so as to improve the air mixing ratio and higher firepower aggregation property and ensure the safety of ignition and stability of production of the tubular heating furnace. The gas nozzle can effectively improve the efficiency of one-time successful ignition when igniting to operate the heating furnace, so as to reduce many unsafe phenomena produced by reignition; and the gas nozzle has the advantages of simple structure and strong adaptability, thereby greatly improving the safety performance of gas-type heating furnace equipment.

Technical field
The utility model relates to a kind of gas nozzle, refers in particular to the gas nozzle that a kind of tubular heater is used.
Background technology
In manufacturing enterprises such as existing Coal Chemical Industry, petrochemical industries, be provided with the gas type heating furnace mostly carrying out the heat transfer process of various ways such as radiation, convection current, thereby it is required to satisfy production technology.Wherein using then is tubular heater comparatively widely, and in order to use safely, existing most tubular heaters all design auxiliary ignition device, and (the little fire-fighting pipe and the ignition of the main burner that promptly ignites are with this main burner that ignites.
Referring to Fig. 1, the ignite auxiliary ignition device of main burner 11 of above-mentioned heating furnace bottom is made up of ignition 13 and combustion gas big fire playpipe 12 and the little fiery playpipe 14 of combustion gas, the combustion gas big fire playpipe 12 in the existing auxiliary ignition device and the burner design of the little fiery playpipe 14 of combustion gas mostly are the cylindrical straight siphunculus, its combustion gas ejection face is irregular diffusion type, be used in the process with ignition 13, because both all are in relative horizontal level, the electric spark that the burning torch head of ignition 13 produces also is round, when combustion gas is concentrated ejection by little fiery playpipe, because of the face that overdoes little, combustion air deficiency etc. often causes once lighting a fire unsuccessful, according to gas type heating furnace safety regulation for operations regulation " when a loss of ignition; must a standard-sized sheet chimney turnover panel and a secondary air register; and all peep holes carried out gravity-flow ventilation 30 minutes or more than, must carry out the interior fuel gas test passes of burner hearth once more before the igniting and can light a fire once more ".So one time loss of ignition will directly influence the continuity of Chemical Manufacture and the security of equipment operation.
The utility model content
The purpose of this utility model is in order to solve the problem that prior art exists, provide a kind of simple in structure, and when the igniting operation that heating furnace is driven, can effectively improve the tubular heater gas nozzle of an ignition success rate, to reduce the many dangerous phenomenon that relight was brought.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tubular heater gas nozzle, it comprises:
The nozzle air feed is responsible for, and is pipe, and an end is fixed in the spout of fuel gas injection pipe, and is communicated with the fuel gas injection pipe;
Three fork-shaped nozzle air feed are in charge of, and are to be in charge of by extended three air feed of the other end that described nozzle air feed is responsible for, and three air feed are in charge of respectively and are communicated with and form three fork-shapeds with the nozzle air feed person in charge;
The nozzle coil pipe is circular coil pipe, and its bottom is in charge of with three air feed that three fork-shaped nozzle air feed are in charge of respectively and is connected and is communicated with, and its inboard is provided with several oval gas jet orifices.
It fixedly is that the employing flange is connected or socket is fixed with the spout of fuel gas injection pipe that described nozzle air feed is responsible for an end.
It is respectively trapezoidal pipe that described three air feed are in charge of, and it is communicated with the diameter of end less than the diameter that is communicated with end with the nozzle coil pipe with the nozzle air feed person in charge.
Described fuel gas injection pipe is combustion gas big fire playpipe and the little fiery playpipe of combustion gas in the auxiliary ignition device of tubular heater bottom.
The beneficial effects of the utility model:
Tubular heater gas nozzle of the present utility model causes the lower dangerous present situation of ignition success rate one time for the fuel gas injection pipe that solves existing cylindrical straight siphunculus type and electronic ignition rifle are used, install one at the spout of cylindrical fuel gas injection pipe and have the nozzle coil pipe that three fork-shaped nozzle air feed are in charge of, offer several oval gas jet orifices in nozzle coil pipe inboard, the combustion gas eddy effusion is come out, to improve air mixed proportion and higher firepower gathering performance, guarantee igniting security of gas type heating furnace and production continuity, especially when the igniting operation that heating furnace is driven, can effectively improve the successful efficient of once lighting a fire, reduce the many dangerous phenomenon that relight brought; In addition, this gas nozzle structure is simple, adaptability is stronger, has improved the safe application performance of gas type heating furnace kind equipment greatly.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is elaborated below with reference to accompanying drawing.
Description of drawings
Fig. 1 is the auxiliary ignition device structural representation of heating furnace bottom;
Fig. 2 is the utility model nozzle schematic side view;
Fig. 3 is the utility model nozzle schematic top plan view.
The specific embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to the specific embodiment of the present utility model.
Referring to Fig. 2-Fig. 3, gas nozzle of the present utility model is used for the combustion gas big fire playpipe of the auxiliary ignition device bottom the tubular heater and the spout of the little fiery playpipe of combustion gas (following general designation fuel gas injection pipe 20), and its structure is as follows:
The nozzle air feed is responsible for 21, is pipe, and an end is fixed in the spout (directly modes such as flange connection or socket are fixed in proportion) of fuel gas injection pipe 20, and is communicated with fuel gas injection pipe 20.
Three fork-shaped nozzle air feed are in charge of 22, are to be responsible for 21 extended three air feed of the other end by the nozzle air feed to be in charge of 221,222,223, three air feed and to be in charge of 221,222,223 and to be responsible for 21 with the nozzle air feed respectively and to be communicated with and to form three fork-shapeds.
