Embodiment approach

[0047] As a preferred embodiment of the present invention, the processing method includes the following steps:

[0048] Step a): preheating the first regenerator and the second regenerator of the regenerative thermal oxidation furnace;

[0049] Step b): After the preheating is completed, the VOCs waste gas is first passed into the first regenerator, and the VOCs waste gas undergoes a decomposition reaction in the first regenerator and the combustion chamber, and the decomposed gas flows through the second regenerator. After the regenerator, it is discharged out of the regenerative thermal oxidation furnace;

[0050] Step c): When the temperature of the first heat storage chamber drops to 500-760°C, stop the introduction of VOCs exhaust gas, and pass clean gas into the first heat storage chamber, so that the residual gas in the first heat storage chamber The VOCs waste gas in the heat chamber continues to flow and heat up, and flows through the second heat storage chamber afte...

Embodiment 1

[0073] Such as figure 1 As shown, this implementation is an industrial VOCs waste gas treatment system, the treatment system includes a regenerative thermal oxidation furnace 30, and the regenerative thermal oxidation furnace 30 is connected to the VOCs waste gas source 20 and the clean gas source 10 respectively through the air inlet system Pass; VOCs waste gas source 20 and clean gas source 10 are supplied to the regenerative thermal oxidation furnace 30 alternately through the air intake system. Wherein, the regenerative thermal oxidation furnace 30 includes a first regenerator 31, a second regenerator 32, and a combustion chamber 33 located between the first regenerator 31 and the second regenerator 32; the first regenerator 31 The second regenerator 32 is respectively connected to the VOCs waste gas source 20 and the clean gas source 10 through the air intake system; The chamber 31 or the second regenerator chamber 32 is supplied with air.

[0074] The air intake system...

Embodiment 2

[0088] Such as figure 2 As shown, this implementation is an industrial VOCs waste gas treatment system. The difference between this embodiment and Embodiment 1 lies in the setting of the air intake system.

[0089] In this embodiment, the air inlet system includes an air inlet pipe 42, and a three-way valve 43 is provided on the air inlet pipe 42. The three-way valve 43 includes two air inlets and one air outlet, and the two air inlets are connected to the clean gas source 10 respectively. And the VOCs exhaust gas source 20, the air outlet communicates with the regenerative thermal oxidation furnace 30 through the air inlet pipe 42.

Abstract

The invention provides an industrial VOCs waste gas treatment method and a treatment system, and relates to the technical field of waste gas treatment. The industrial VOCs waste gas treatment method comprises the following steps: VOCs waste gas and clean gas are alternately introduced in a heat storage type thermal oxidation furnace. The treatment method can increase the purifying rate of the VOCs waste gas, reduces the equipment cost, is simple and feasible, and is easy to realize industrial production.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an industrial VOCs waste gas treatment method and treatment system. Background technique [0002] In the field of industrial waste gas VOCs (volatile organic compounds, volatile organic compounds) treatment, the most commonly used method is the thermal oxidation method, that is, the VOCs in the waste gas are completely oxidized and decomposed into carbon dioxide and water at high temperature (above 760°C) to achieve purification purpose of exhaust. [0003] Regenerative thermal oxidation furnace, English abbreviation: RTO, because of its high heat recovery rate, high processing efficiency, safety, stability, and full automation, it meets the requirements for environmental protection under large-scale industrial production conditions, so regenerative thermal oxidation Furnaces are the most widely used in the world. Especially in developed countries in Europe and the ...
