Abstract
Description
Technical Field
[0001] The present application relates to the field of environmental protection technologies, and specifically to a device for co-processing volatile organic compounds using a boiler. Background Art
[0002] Volatile organic compounds (VOCs) are a common type of air pollutant, mainly sourced from industrial production, transportation, and chemicals used in daily life. VOCs not only pose hazards to human health but also trigger atmospheric chemical reactions, leading to environmental problems such as photochemical smog, ozone layer depletion, and the greenhouse effect. Therefore, how to effectively treat VOCs has become an important topic in the current environmental protection field. Traditional VOC treatment methods include adsorption, absorption, condensation, and combustion (RTO, RCO), etc. However, the methods of adsorption, absorption, and condensation have problems such as low treatment efficiency and easy generation of secondary pollution. The RTO and RCO methods must perform pre-concentration treatment on low-concentration exhaust gases, with high processing costs and numerous problems during operation.
[0003] With the development of industry, VOC emissions have had a serious impact on the environment and human health. Currently, the methods for treating VOCs have problems such as high costs and low efficiency. Utility Model Content
[0004] Aiming at the deficiencies of the prior art, the present application provides a device for co-processing volatile organic compounds using a boiler, which has the advantage of fully burning VOCs and solves the problems of high cost and low efficiency in treating VOCs.
[0005] To achieve the above object, the present application provides the following technical solution: A device for co-processing volatile organic compounds using a boiler, comprising a boiler body, a secondary air blower, an air preheater, a secondary air pipeline, and a spray gun. The air preheater is connected to the outlet of the secondary air blower through a pipeline, and the air preheater is connected to the spray gun through the secondary air pipeline. A plurality of groups of the spray guns are installed on the inner wall of the boiler body, and the air sprayed by the spray guns is ejected to the upper part of the combustion zone of the furnace of the boiler body to form over-fire air.
[0006] By introducing VOCs into the boiler combustion process, the high-temperature decomposition and harmless treatment of VOCs are realized using the high-temperature environment of the boiler body. By optimizing the combustion process of the boiler body, the efficient treatment of VOCs and the recovery and utilization of energy are achieved, reducing environmental pollution.
[0007] Preferably, one side of the boiler body is connected to a primary air blower through a pipeline, and the inlet of the primary air blower is connected to a first VOC delivery pipeline.
[0008] When the primary air blower is started, the VOC exhaust gas inside the first VOC delivery pipeline is introduced into the boiler body for combustion.
[0009] Preferably, the air inlet of the secondary air blower is connected to a second VOC pipeline.
[0010] Preferably, the other side of the boiler body is connected to the air preheater through a pipeline.
[0011] The waste gas containing VOC is introduced into the air preheater through the second VOC pipeline, and the waste gas containing VOC is preheated inside the air preheater.
[0012] Preferably, several groups of the spray guns are linearly distributed inside the boiler body.
[0013] The air sprayed by the spray gun is ejected to the upper part of the combustion zone of the furnace of the boiler body to form overfire air, so that the VOC in the waste gas is fully combusted.
[0014] In summary, the present application includes at least one of the following beneficial effects:
[0015] 1. For the device for co-processing volatile organic compounds using a boiler, by introducing VOC into the boiler combustion process, the high-temperature decomposition and harmless treatment of VOC are realized by using the high-temperature environment of the boiler.

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0020] Please refer to Figure 1, a device for co-processing volatile organic compounds using a boiler, comprising a boiler body 1, a secondary air blower 5, an air preheater 6, a secondary air pipeline 7 and a spray gun 8. The air preheater 6 is connected to the outlet of the secondary air blower 5 through a pipeline. The inlet of the secondary air blower 5 is connected to a second VOC delivery pipeline 4. The air preheater 6 is connected to the spray gun 8 through the secondary air pipeline 7. After the secondary air blower 5 is started, the secondary air blower 5 feeds VOC into the air preheater 6, and the waste gas containing VOC is preheated inside the air preheater 6. The other side of the boiler body 1 is connected to the air preheater 6 through a pipeline. A number of groups of spray guns 8 are installed on the inner wall of the boiler body 1. The air sprayed by the spray guns 8 is ejected to the upper part of the furnace combustion area of the boiler body 1 to form over-fire air. VOC is fed into the boiler body 1 through the secondary air pipeline 7 and the spray gun 8. A number of groups of spray guns 8 are linearly distributed inside the boiler body 1. One side of the boiler body 1 is connected to a primary air blower 2 through a pipeline, and the inlet of the primary air blower 2 is connected to a first VOC delivery pipeline 3.
[0021] Working principle: The VOC collection system is responsible for collecting VOC generated during industrial production processes and transporting it to the VOC delivery system. The VOC delivery system sends the collected VOC to the boiler combustion system for combustion together with the boiler fuel. The waste gas of VOC can be introduced into the boiler body 1 through the pipeline connected to the primary air blower 2, or through the pipeline connected to the secondary air blower 5, or simultaneously through the pipelines connected to the primary air blower 2 and the secondary air blower 5 into the boiler body 1. In the boiler combustion system, the oxygen content of the waste gas containing VOC is equivalent to that of air. Here, the VOC waste gas completely replaces air to supply oxygen for the boiler to burn. VOC is decomposed into harmless substances under a high-temperature oxidation atmosphere, and at the same time, heat energy is released to provide heat for the boiler. Introducing VOC from the secondary air pipeline 7, passing through the air preheater 6, and the spray gun 8 delivering VOC, and spraying the VOC waste gas into the upper part of the combustion area through the spray gun 8 can effectively reduce the generation of nitrogen oxides and improve the combustion efficiency, having the advantages of simple structure, convenient operation, good environmental protection effect, etc.

The scope of the present application is defined by the appended claims and their equivalents.
