Embodiment 1

[0036] The fluid mixer is used to mix a variety of gases before combustion and other links. The uniformly mixed gas helps to stabilize the combustion process, improve the sufficiency of the combustion process and reduce the harmful components in the combustion products.

[0037] Especially for fluid mixers before the combustion process, safety is also an aspect worth paying attention to. In order to avoid the explosion of combustible gas and combustion-supporting gas before combustion, the combustible gas and combustion-supporting gas usually meet and mix during the combustion process. Insufficient mixing results in unstable combustion process and incomplete combustion products contain harmful components. The fluid mixer provided in this embodiment improves the safety before combustion and makes the combustible gas and the combustion-supporting gas fully mixed.

[0038] This embodiment provides a specific implementation of a fluid mixer, refer to figure 1 , the fluid mixer co...

Embodiment 2

[0053] This embodiment provides a specific implementation of a combustion device, refer to image 3 , the combustion device comprises the fluid mixer described in Example 1, and

[0054] A combustion chamber communicated with the fluid mixer, the combustion chamber is provided with a burner and an igniter.

[0055] Specifically, the organic waste gas pipeline 501 and the combustion-supporting gas pipeline 502 are the same as the cavity of the fluid mixer. The organic waste gas and the combustion-supporting gas are first mixed by a mixing element, and then mixed with the air introduced in the air pipe 503 after passing through the mixing element. After mixing, it reaches the metal fiber surface burner 7, and the igniter 6 communicates with the igniter pipeline 504 to ignite and burn the mixed gas reaching the metal fiber surface burner 7.

[0056] This embodiment provides a specific implementation of the burner, and continues to refer to image 3 , the mixing element is arran...

Embodiment 3

[0069] In this example, the VOCs gas comes from the waste gas generated in the refined oil product storage area. When the treated VOCs gas comes from the exhaust gas generated in the refined oil product storage area, the waste gas has the following characteristics: continuous operation, large concentration change, and average oxygen content Below 3%, the flow fluctuates greatly.

[0070] Natural gas is used as the supporting gas when treating the waste gas generated in the refined oil product storage area.

[0071] The exhaust gas, air and auxiliary gas generated in the refined oil product storage area respectively enter the fluid mixer 100 through the pipeline, and enter the combustion chamber after being mixed by the mixing element 2 .

[0072] Structures such as pipelines for conveying auxiliary gas, VOCs gas, and air are equipped with flame arresters, monitoring instruments, flow control valves, safety isolation valves and other components to realize the isolation, safety,...

Abstract

The application provides a fluid mixer, a combustion device including the same, and a method for treating VOCs gas, including: a cavity, including an inlet and an outlet; a mixing element, a plurality of baffle structures are arranged in the mixing element, and spaces between the baffle structures It constitutes a passage for fluid to pass through; the mixing element divides the interior of the cavity into several sub-cavity units, and the communication channel between each sub-cavity unit is only a mixing element. The baffle structure reflects the flowing gas impinging on it, so that the flow direction of the gas changes irregularly. For multiple gases that need to be mixed, the flow direction after being reflected is not regular, so the mixing is more uniform. . In this application, the cavity of the fluid mixer is divided into a plurality of sub-chamber units. When combustion occurs in one of the sub-chamber units, the blocking of the mixing element can prevent the combustion from extending to other sub-chamber units divided from it, thus The safety of the mixing process is improved.

Description

technical field [0001] The invention belongs to the technical field of mixers, in particular to a fluid mixer, a combustion device including the same, and a method for treating VOCs gas. Background technique [0002] The mixer is used to mix various gases, and the mixed gases are more uniform. For combustion, a uniform mixture of gas heating flame temperature field distribution is more uniform and NO in the flue gas after combustion X , VOCs emission is low. [0003] The safety problems of mixers in the prior art are rarely involved, and the present invention aims to solve the problems of sufficiency and safety of the above-mentioned mixing process. SUMMARY OF THE INVENTION [0004] In view of the above technical problems existing in the prior art, the present invention provides a fluid mixer, a combustion device including the same, and a method for treating VOCs gas. [0005] The fluid mixer provided in this application includes: [0006] Cavity, including inlet and o...
