Container type combustion device with function of increasing air injection volume

Abstract

Provided is a container type combustion device with a function of increasing the air injection volume. The device comprises multiple layers of protective covers which are arranged in the vertical direction and a Venturi combustor unit; each layer of the protective cover is closed in the circumferential direction to form a flame cavity with the upper opening end and the lower opening end, each layer of the protective cover is shaped like a rectangle and comprises a first pair of opposite side plates and a second pair of opposite side plates, the first pair of the opposite side plates and the second pair of the opposite side plates are connected with each other to form the rectangle, and an injection area which is communicated with a flame cavity fluid is formed between the first pairs of the opposite side plates of two adjacent layers of the protective covers; the Venturi combustor unit comprises multiple layers of Venturi combustors, and the head of each layer of the Venturi combustor is located on the inner side of the corresponding layer of the protective cover.

Description

technical field [0001] The invention relates to a combustion device, in particular to a container type combustion device with increased air injection volume. Background technique [0002] In petrochemical plants, the venting flare system can deal with redundant, harmful, and unbalanced waste gas discharged from production plants in a timely manner, and can also deal with unqualified gas generated during commissioning, start-up and shutdown, and a large amount of gas released instantaneously during accidents, ensuring that the plant Normal and safe operation. [0003] The vent flare system generally adopts an ejector type combustion device, which includes a number of Venturi burners to burn the gas. In a combustion device of the prior art, multiple rows of parallel burners are arranged in a straight line on a plane, and there is a situation in which the amount of air introduced by the burners in the middle part is insufficient, resulting in low combustion efficiency, and ins...

AI Technical Summary

Problems solved by technology

In a combustion device of the prior art, multiple rows of parallel burners are arranged in a straight line on a plane, and there is a situation in which the amount of air introduced by the burners in the middle part is insufficient, resulting in low combustion efficiency, and insufficient air makes the combustion of gas difficult. Sufficient, will produce a lot of harmful emissions, such as carbon monoxide, nitrogen oxides, etc.

In another kind of combustion device, the burners are arranged in the vertical direction in a multi-layer annular manner. Although the problem of the amount of air injection can be solved, the annular structure requires an annular protective cover and an annular intake pipe, which requires relatively high requirements for the manufacturing process. high, difficult to reduce costs
