Problems solved by technology

[0004] The invention utilizes different numbers of unit burners to form landfill gas incineration torches with corresponding rated loads. The device ideally solves the characteristics of large load variation range and air pressure fluctuations of landfill gas. The stable incineration of landfill gas with flow rate and large fluctuation range can adapt to the gas production characteristics of Chinese waste landfills

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings, but it should be pointed out that the following words are only for illustration, rather than limitation.

[0023] exist figure 1 Among them, different numbers of burners form burner groups arranged in a ring, and the number of groups can be selected according to different landfill gas volumes. figure 1 Two sets of annular burner stacks are shown in , four brackets support the burner stacks with different diameters, and a pipe carries landfill gas to the burner stacks for combustion.

[0024] figure 2 Among them, the landfill gas from the landfill gas main pipe of the waste landfill first passes through the manual valve 1 (the sewage valve 4 is installed on the main pipe), and then enters the flare tower through the branch pipe composed of three seamless steel pipes; the three branch pipes are respectively It is connected with the ignition torch, the main burner and th...

Abstract

The invention relates to flare tower and its combustion apparatus and unit burner. It includes many circular ring tubes with the same axis but not the same plane. Each of the circular ring tubes is set certain unit burner to form unit burner set. Its features are that each circular ring is connected to landfill gas sub-lateral by U-tube. The sub-lateral can form main. The interval of the U-tube top end is equal to circular ring tube nominal diameter. The vertical section of the former and the horizontal section of the latter are vertical. The sub-lateral is vertically connected to U-tube. It also includes electricity strike fire burning torch. Its accordant adjusting ratio can reach 100:1. The combustion is stable, and not easy to be flameout.

Description

Technical field [0001] The present invention is a torch device designed for the characteristics of landfill gas, which can be stably, fully and rapidly burned when the flow rate of landfill gas is changed in a relatively large range, especially to make the combustion of landfill gas become It is easier to control, and it is mainly used in landfill gas incinerators and can also be used as an absorptive treatment for anaerobic fermentation gas production in sewage treatment and manure treatment. Background technique [0002] Landfill gas is the gas produced by anaerobic fermentation after landfill, in which CH 4 The content is about 50% to 70%, CO 2 The content is about 30% to 50%, and contains a small amount of water vapor, H 2 S and other trace gases. If the landfill gas in the landfill site is not actively sucked and disposed of, it will easily cause pile incineration and explosion accidents. In addition, methane in landfill gas is a greenhouse gas, and its greenhouse ef...
