New large-capacity enclosed ground flare

Abstract

The invention discloses a new large-capacity enclosed ground flare, which includes a combustion chamber, a plurality of burners arranged in the combustion chamber, exhaust gas branch pipes connected with the plurality of burners, and an ignition control system; the exhaust gas The branch pipe is connected through the gas collecting main pipe; the characteristic is that the cross-section of the combustion chamber is rectangular, and the burners are arranged in rows in the combustion chamber. Since the combustion chamber is designed as a rectangular combustion chamber, it can be designed according to the shape of the site plot, reducing the floor space and saving land resources, so as to meet the requirements of multiple production devices or multiple factories sharing the torch system, thus adapting to various designs of processing capacity. The processing capacity of a single seat can reach 300t / h~1000t / h, far exceeding the processing capacity of the cylindrical combustion chamber. Combined with the arrangement of burners in rows and rows, the arrangement of burners is simpler, which is beneficial to simplify the hierarchical pipeline and control, facilitate inspection and maintenance, and ensure that each burner gets enough air to improve the combustion effect.

Description

technical field [0001] The invention relates to a novel large-capacity enclosed ground flare. Background technique [0002] The large enclosed ground flare can be flexibly adapted to various throughput requirements while improving the combustion effect. At present, the combustion chambers of closed ground flares all adopt a cylindrical structure. Due to structural limitations, the maximum processing capacity of a single cylinder generally does not exceed 120t / h. [0003] The utility model patent ZL00263385.X discloses a "Ground Torch Discharging Device". The characteristic of the ground torch discharging device is that it uses the pulling force of the cylindrical combustion chamber to form a certain negative pressure in the combustion area, so that the outside air enters combustion chamber. According to its structure and combustion effect, this kind of ground torch is usually called "cylindrical closed ground torch". [0004] The shortcomings of the above-mentioned "cylin...

AI Technical Summary

Problems solved by technology

When the design capacity of the flare increases, a large-diameter combustion chamber is required. In order to ensure the pulling force effect, the height of the combustion chamber needs to be increased, which leads to a sharp increase in the investment of the flare system and increases the difficulty of design;

[0007] 2. Insufficient air in the central area of ​​the combustion chamber:

Therefore, the open ground torch occupies a large area and cannot save land resources well;

[0011] 2. Because the burner burns in an open environment, it is prone to blow out, fire off, black smoke and other phenomena. In order to avoid these phenomena, a burner with a special structure is required, and the requirements for the hierarchical control system are relatively high. ;

[0012] 3. The metal fence around the open ground torch is low, so it is difficult to avoid the impact of heat radiation and light pollution on the high altitude around the torch
