Description

Petrochemical torch burner without ignition pilot burner

Technical Field

The utility model relates to the technical field of safe venting torch facilities, in particular to a petrochemical torch burner without an ignition pilot burner.

Background

The emptying flare tip is used for treating waste gas and toxic gas or combustible gas under accident conditions generated by petrochemical equipment and can be divided into a ground flare combustor or an overhead flare combustor. Performance requirements of the venting torch: 1. the discharge combustion is stable and no backfire occurs under the designed working condition. 2. Complete combustion, no smoke and environmental protection. 3. The flare tip is equipped with a dynamic sealing mechanism. 4. The combustion noise of the emptying torch is low, and the requirement of environmental noise is met. 5. The operation and maintenance of the emptying torch are simple, and the operation cost is low.

The conventional burner is ignited by requiring the pilot burner to be ignited, the pilot burner is ignited by a manual or automatic ignition device, and the pilot burner flame ignites the combustible exhaust gas. The ignition source of the petrochemical torch burner without the need to ignite the pilot burner comes from an adjacent existing burner flame or an adjacent security fire source. At present, a burner, a pilot burner and an ignition facility form a complete flare system, and the existing related equipment has the defects of large facility, complex structure, high fuel consumption and the like.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a petrochemical flare burner that does not require an ignition pilot lamp to solve the problems set forth in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme:

need not to ignite petrifaction torch combustor of changming lamp, be responsible for, get trachea and biography firetube including combustion head, combustible gas, the combustible gas is responsible for the upper end and erects the connection and gets the trachea, get the trachea upper end and connect and pass the firetube, the combustible gas is responsible for the upper end opening and arranges fixed combustion head, it gets the trachea to insert on the combustible gas main pipe outer wall.

As a further scheme of the utility model: the combustion head is of a wine glass structure, and the diameter of the combustion head is 150% of the outer diameter of the upper port pipe of the combustible mixed gas main pipe.

As a further scheme of the utility model: the inner diameter of the main combustible gas pipe is larger than that of the gas taking pipe.

As a further scheme of the utility model: the gas taking pipe connecting position is located 30 cm below the bottom end opening of the combustion head.

As a further scheme of the utility model: the level height of the fire transfer pipe is the same as that of the outlet of the main fuel gas pipe.

As a further scheme of the utility model: the fire transmission pipe is connected with the main combustible gas pipe by welding.

Compared with the prior art, the utility model has the beneficial effects that: the ignition, flame transmission and combustion head are integrated into a whole, the pilot burner and ignition facilities are omitted, the structure is simple, the flame of the adjacent burner or a safety fire source is directly used for ignition, and the utility model has the advantages of simplifying equipment composition, saving fuel gas, improving reliability and the like.

FIG. 1 is a schematic diagram of a petrochemical flare burner without an ignition pilot lamp according to an embodiment of the present invention.

Notations for reference numerals: 1-combustion head, 2-main pipe of combustible gas, 3-air intake pipe and 4-fire transmission pipe.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As an embodiment of the present invention, please refer to fig. 1: need not petrochemical industry torch combustor of ignition changming lamp, be responsible for 2, get trachea 3 and pass firetube 4 including combustion head 1, combustible gas, the combustible gas is responsible for 2 upper ends and erects to connect and gets trachea 3, get 3 upper end connection of trachea and pass firetube 4, the combustible gas is responsible for 2 upper end openings and arranges fixed combustion head 1, the combustible gas is responsible for and inserts on 2 outer walls and gets trachea 3.

In this embodiment, the combustion head 1 is a wine glass structure, and the diameter of the combustion head 1 is 150% of the outer diameter of the upper port of the main fuel gas pipe 2.

In this embodiment, the inner diameter of the main combustible gas pipe 2 is larger than the inner diameter of the gas intake pipe 3.

In the embodiment, the access position of the gas taking pipe 3 is 30 cm below the bottom port of the combustion head 1; the reliability and the service life of the air intake pipe 3 are ensured.

In this embodiment, the level of the flame transmitting pipe 4 is the same as the level of the outlet of the main fuel gas pipe 2.

In this embodiment, the flame propagation tube 4 is connected to the main fuel gas pipe 2 by welding.

The working principle is as follows: the fire transmission pipe 4 is a pipeline with a proper pipe diameter, and the pressure drop in the fire transmission pipe 4 is not more than the resistance drop of the main combustible gas pipe 2; ignition fuel gas is supplied by a gas taking pipe 3 connected with the root of a main combustible gas pipe 2, combustible gas with certain pressure enters the gas taking pipe 3 and then enters a fire transfer pipe 4 to be ignited by flame arranged close to a burner or a safety fire source, and the fire transfer flame reaches a combustion head 1 to complete reliable and stable ignition flame.
