Problems solved by technology

Judging from the actual usage of the user, the forced ventilation torch equipped with a fan can still operate normally for a small gas volume torch. Changes are also constantly changing according to changes in the production process or unexpected situations. The air distribution capacity of the same fan is difficult to match in time with the change in biogas volume, resulting in too much air volume at the beginning of ignition or when re-igniting after flameout, affecting normal ignition and combustion. However, when the amount of biogas is large, the air distribution cannot keep up with it, which may cause incomplete combustion, fail to meet environmental protection emission requirements, and pose safety hazards.
[0006] Existing torch technology uses one way to ignite the permanent lamp and one way to flame detector. For the large volume torch, due to the large diameter of the torch cylinder, the ambient wind direction and air volume will have a certain impact on the stability of the torch gas supply during natural suction. When the amount is small, the fullness of the flame is small, and the ignition lamp and flame detection all the way cannot guarantee timely and correct completion of ignition and flame detection, resulting in ignition failure or false alarm
Affect the normal and safe combustion operation of the flare
[0007] Due to the safe and stable combustion of existing torch burners, the scope of application for biogas is relatively small, and sometimes the project is large, and the final gas production is constantly increasing. In order to meet the use requirements, multiple torches have to be installed to deal with emergency combustion needs, resulting in site occupation. Large, complex pipeline and control, greatly increased production and operation costs

Embodiment 1

[0033] The present invention provides such as Figure 1-2 A segmented gas flare combustion system shown, including flare 1;

[0034] And multiple groups of nozzles 2 arranged in the torch 1, the multiple groups of the nozzles 2 correspond to the multi-stage burner valve group 3; also include a gas distribution pipe 4 and a plc control system, the gas distribution pipe 4 and the multi-stage burner valve group 3; The stage burner valve group 3 is connected, and the plc control system is used to control the gas supply amount of the gas distribution pipe 4 to the multi-stage burner valve group 3 and the corresponding multiple groups of nozzles.

[0035] The multi-stage burner valve group 3 includes: a first-stage burner valve group 301, a second-stage burner valve group 302, a third-stage burner valve group 303; the first-stage burner valve group 301, the second-stage burner valve group The group 302 and the three-stage burner valve group 303 are both communicated with the gas di...

Embodiment 2

[0040] The technical route of the segmented gas flare combustion system in this embodiment is to design the flare burner into segments and adopt a staged combustion method, that is, the flare burner is designed into two or three through the gas distribution pipe, which can operate independently and Two-stage or three-stage flare burners that can be operated in combination, and the nozzles of each branch flare burner are evenly distributed in the flare barrel. The start and stop of the flare burners at all levels can be controlled by the program and put into operation in stages according to the change of the gas volume, or it can be manually started and stopped.

[0041] The composition of the segmented flare burner, the main intake pipe is connected to the gas distribution pipe set before the torch, and the gas is divided into two or three-way staging burner intake pipes through the gas distribution pipe, and the diameter of each staging burner intake pipe is According to the ...

Abstract

The invention discloses a sectional type fuel gas torch combustion system which comprises a graded burner valve group, wherein a gas inlet main pipe is connected into a fuel gas distribution pipe, the caliber of each stage of branch fuel gas pipe is determined according to the designed and distributed combustion gas quantity of each stage, and each stage of branch fuel gas pipe is provided with a manual valve, a pneumatic or electric valve and a flame arrester with corresponding caliber. Combustion gas supply of combustion heads of nozzle pipes of the corresponding staged combustors which are independently and uniformly distributed in the torch is controlled, and when the staged combustors are put into use, fuel gas is sprayed out of the combustion heads and is combusted after being ignited by the ignition incandescent light. The air inlet amount is automatically adjusted according to the combustion gas amount and intensity, one part is evenly mixed with fuel gas sprayed out of the evenly-distributed combustion heads to provide needed oxygen, the redundant part is further mixed with combusted flue gas, the temperature of the exhausted flue gas is lowered, and the heat radiation influence is reduced. The combustor can adapt to the large-range change of the gas amount in a mode of staged combustion of staged feeding of all stages of combustors in a very wide flow range, and stable, safe and smokeless combustion and up-to-standard emission can be realized.

Description

technical field [0001] The invention belongs to the technical field of burners, and in particular relates to a segmented gas torch combustion system. Background technique [0002] By-product biogas will be produced in various anaerobic fermentation processes such as garbage disposal leachate, sewage treatment, livestock farm manure treatment, and biopharmaceuticals. The main component of biogas is methane, which is a greenhouse gas. According to environmental protection requirements, it is not allowed. directly discharged. The biogas with methane as the main component produced in the process of anaerobic treatment must use its thermal energy through combustion, or be burned by torches and then discharge up to the standard; there are other gases (natural gas, coal gas, liquefied gas, etc.) in the process of storage and transportation. There are also requirements for emergency combustion and discharge of excess gas; flare burners are the core equipment for flare combustion an...
