Description
Technical Field
[0001] The present invention relates to the technical field of organic waste gas treatment, and in particular to an organic waste gas pretreatment device based on a regenerative oxidation incinerator and a use method thereof. Background Art
[0002] Waste gas incinerator is a device that uses the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible harmful gases to the reaction temperature, thereby causing oxidation and decomposition. There are two types of waste gas incinerators: "direct combustion" and "heat storage". The so-called "direct combustion" means that only the waste gas is burned, and the heat is not recovered. However, most of the waste gas incinerators used in the copper clad laminate industry recover heat to heat the gluing machine. In fact, the principles of "direct combustion" and "heat storage" are the same, and the difference is only whether there is heat storage material in the furnace. Waste gas incinerators are suitable for waste gas treatment of spraying and drying equipment, and purification of harmful gases emitted by petrochemical, pharmaceutical and other industries.
[0003] With the development of society, there are more and more heavy industries. Many chemical plants will produce a lot of organic waste gas in the production process. Organic waste gas is often accompanied by many harmful gases that are not good for the air. Therefore, it cannot be discharged directly. There are also many devices for treating organic waste gas. Most of the treatment methods use physical adsorption or chemical reaction to treat the waste gas.
[0004] However, in actual use, the existing oxidation incinerator has a relatively high flammability during the chemical combustion of organic waste gas. If it continues to burn, it is easy to cause an explosion in the pipeline or furnace, thereby causing dangerous accidents, and its practicality is poor. Summary of the invention
[0005] Based on the technical problem that in the process of treating organic waste gas by chemical combustion in the existing oxidation incinerator, the organic waste gas has a relatively high flammability. If it continues to burn, it is easy to cause an explosion in the pipeline or the furnace, thereby causing a dangerous accident, the present invention proposes an organic waste gas pretreatment device based on a regenerative oxidation incinerator and a method of use.

[0014] An organic waste gas pretreatment device based on a regenerative oxidation incinerator and a method of use, comprising the following steps:
[0015] S1: When in use, first introduce the organic waste gas into the device through the air inlet tube. At this time, as more and more organic waste gas enters the spherical airbag, the pressure inside the spherical airbag becomes larger and larger under the action of the organic waste gas, so the volume of the spherical airbag also becomes larger and larger. When the pressure inside the spherical airbag is greater than the maximum pressure set by the pressure limiting valve, the pressure limiting valve automatically opens, and at this time, all the organic waste gas in the spherical airbag is ejected from the outlet of the spherical airbag;
[0016] S2: The ejected organic waste gas enters the gas dispersion hopper. The gas dispersion holes on the gas dispersion hopper can disperse the high-pressure airflow and gradually disperse it into the entire sphere. At this time, people can start the suction pump to suck air into the air storage box. The air in the air storage box can push the air baffle and the rotating ring to rotate along the slide rail through the air inlet hole. While rotating, the air and the organic waste gas can be fully mixed, thereby providing a sufficient combustion-supporting environment for the organic waste gas.
[0017] S3: At this time, start the ignition rod to ignite the organic waste gas, allowing the organic waste gas to burn fully inside the sphere. A lot of solid particles may be produced in the organic waste gas after combustion. Driven by the air flow, the waste gas after combustion enters the intake pipe through the intake hopper, and then enters the ceiling through the intake pipe, and finally enters the water in the water tank through the gas pipe, so that the organic waste gas after combustion can be cleaned to prevent excessive solid particles from entering the atmosphere with the gas, which is clean and environmentally friendly.
[0018] The beneficial effects of the present invention are:
[0019] 1. The present invention is provided with an air inlet cylinder, an air collecting hopper, a spherical air bag, a pressure limiting valve, an air dispersion hopper and an air dispersion hole. When the organic waste gas enters the spherical air bag through the air collecting hopper, the pressure inside the spherical air bag becomes larger and larger under the action of the organic waste gas, so the volume of the spherical air bag also becomes larger and larger. When the pressure inside the spherical air bag is greater than the maximum pressure set by the pressure limiting valve, the pressure limiting valve automatically opens. At this time, all the organic waste gas in the spherical air bag is ejected from the outlet of the spherical air bag, and the ejected organic waste gas enters the air dispersion hopper. The air dispersion hole is The air holes on the bucket can disperse the high-pressure airflow, gradually disperse it into the entire sphere, and then ignite this part of the organic waste gas through the ignition rod, so that this part of the organic waste gas can be fully burned inside the sphere. At the same time, the spherical airbag prepares for the next organic waste gas combustion and inflation. Through this intermittent incineration of the organic waste gas, the pipeline can be blocked during the combustion process to prevent the gas from leaking around the pipeline and causing an explosion. At the same time, it can prevent the organic waste gas from continuously entering the sphere and causing incomplete combustion.
[0020] 2. The present invention is provided with an air suction pump, an air storage box, a slide rail, a swivel, a slip ring and an air baffle. The air is sucked into the air storage box by the air suction pump. The air in the air storage box can push the air baffle and the swivel to rotate along the slide rail through the air inlet hole. During the rotation, the air and the organic waste gas can be fully mixed, thereby providing a sufficient combustion-supporting environment for the organic waste gas. At the same time, it can also ensure that the organic waste gas is evenly distributed inside the sphere, thereby ensuring that the organic waste gas can be fully burned.
[0021] 3. The present invention is provided with a ceiling, a water tank, an air intake pipe and an air supply pipe. A lot of solid particles may be generated in the organic waste gas after combustion. Driven by the air flow, the waste gas after combustion enters the air intake pipe through the air intake hopper, then enters the ceiling through the air intake pipe, and finally enters the water in the water tank through the air supply pipe, so that the organic waste gas after combustion can be cleaned to prevent excessive solid particles from entering the atmosphere with the gas, which is clean and environmentally friendly.
