Abstract

The invention discloses a ground ignition device for a petrochemical flare system. The ground ignition device comprises a gas mixing part, at least two air inlet parts, a velocity reduction tube and an ignition element, wherein one end of the gas mixing part is used for communicating with a fuel gas pipeline so as to mix fuel gas delivered by the fuel gas pipeline with air; the air inlet parts arearranged on the gas mixing part, and the inlet area of air inlets is adjustable; one end of the velocity reduction tube communicates with the other end of the gas mixing part, and the velocity reduction tube is used for reducing the flow velocity of mixed gas in the gas mixing part; and the ignition element is arranged on the velocity reduction tube and used for igniting the mixed gas. The problem that an independent air supply part needs to be arranged in the prior art is avoided, and thus the ignition device is simple in structure, capable of reducing cost and convenient to operate.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to a ground ignition device for a petrochemical flare system. Background technique [0002] The torch system is a special combustion facility used to deal with flammable and combustible toxic gases and vapors that cannot be recovered and reprocessed in petrochemical plants, refineries, chemical plants and other plants or devices. an important measure. The ignition device of the flare system is a device used to ignite the flammable and combustible toxic gases in the flare system. [0003] The prior art includes a series of ignition devices, such as high-altitude ignition devices, ground ignition devices, and the like. Among them, the ground ignition device is favored by the industry due to its advantages of safety, stability and easy maintenance. [0004] Regarding ground ignition devices such as figure 1 As shown, the fuel gas and air enter the ejector premixer for ignitio...
