[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1As shown, an environmentally friendly packaging material board composite device includes a composite device body, which includes a frame with a composite station 11 on the frame. The composite station is where at least two sheets of paper coated with adhesive are laminated together. In front of the composite station is a baking station 12, which dries the adhesive on the laminated packaging paper. A baking oven 2 is installed to the side of the baking station. The heat radiated by the baking oven heats the baking area, causing the moisture in the adhesive to evaporate, thus achieving packaging... The paper drying process includes a combustion furnace 3 that provides heat to the baking oven. The combustion furnace has a high-temperature air chamber 31, which is connected to the baking oven via an air inlet pipe 32. The baking oven 2 is connected to the high-temperature air chamber via a return air pipe 21, forming a hot air circulation channel. A circulation pump 22 is installed in the middle of the hot air circulation channel. The combustion furnace has a tail gas exhaust pipe 33. The process is characterized by further including a zeolite rotor 4, which has a rotor inlet 41 and a rotor outlet 42. The tail gas exhaust pipe 33 is connected to the inlet of the conversion rotor.

[0013] It should be noted that the composite device body and the zeolite rotor are components in the prior art.

[0014] For example, the zeolite rotor is a highly efficient VOCs (volatile organic compounds) waste gas treatment technology, particularly suitable for treating large volumes of low to medium concentration organic waste gas. This process combines the concentration capacity of the zeolite rotor with the oxidative decomposition capacity of the RTO, achieving the goals of energy saving, emission reduction, and economical operation. The zeolite rotor is a rotating adsorption device, its core being a honeycomb structure composed of zeolite molecular sieves. Zeolite has high hydrophilicity and selective adsorption capacity, enabling it to capture and concentrate VOCs from waste gas. The zeolite rotor is divided into three zones: an adsorption zone, a desorption (regeneration) zone, and a cooling zone. 1. Adsorption Zone: When low-concentration organic waste gas passes through the adsorption zone of the zeolite rotor, VOCs are adsorbed by the zeolite molecular sieves, and the purified gas is directly discharged. 2. Desorption (Regeneration) Zone: When the zeolite rotor rotates to the desorption zone, high-temperature air (usually 180-220°C) is used to heat the zeolite, causing the adsorbed VOCs to desorb and form high-concentration VOCs vapor. 3. Cooling Zone: After desorption, the zeolite passes through the cooling zone to restore its adsorption capacity, preparing it to adsorb VOCs in the exhaust gas again.

[0015] The above-mentioned configuration of this utility model can achieve the combustion of harmful gases in the exhaust gas generated by the combustion furnace on the composite device, thus achieving the purpose of this utility model. Generally speaking, the purification rate can reach 90%.

[0016] Furthermore, it also includes an RTO regenerative thermal converter 5, which has a converter inlet 51 and a converter outlet 52, and the rotor outlet 42 is connected to the converter inlet 51.

[0017] It should be noted that the RTO regenerative converter is a component in the prior art.

[0018] For example, the RTO (Regenerative Thermal Oxidizer), also known as a regenerative thermal incinerator or regenerative oxidizer, works on the principle that if the organic matter contains halogens or other elements, the oxidation products will also include hydrogen halides. The waste gas is first heated to near its thermal oxidation temperature by a heat storage medium, and then enters the combustion chamber for thermal oxidation. The oxidized gas has a higher temperature, and the organic matter is essentially converted into carbon dioxide and water. The purified gas then passes through another heat storage medium, where its temperature decreases, and it can be discharged after meeting emission standards. The different heat storage mediums are switched over time via switching valves or rotating devices, allowing for heat absorption and release respectively.

[0019] The principle is as follows: Organic waste gas is heated to over 760 degrees Celsius, causing the VOCs in the waste gas to oxidize and decompose into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and "store heat." This "stored heat" is used to preheat the subsequently entering organic waste gas, thus saving fuel consumption for heating the waste gas. The ceramic heat storage body should be divided into two (or more) heat storage chambers. Each heat storage chamber sequentially undergoes a heat storage-heat release-cleaning process, repeating continuously. After the heat storage chamber "releases heat," a portion of the treated clean gas should be immediately introduced to clean the heat storage chamber (to ensure a VOC removal rate of over 95%). Only after cleaning is completed can the "heat storage" process begin.

[0020] The above-mentioned features of this invention can further combust the harmful gases in the exhaust gas generated by the combustion furnace on the composite device. Generally speaking, the exhaust gas purification rate can reach 98%.

[0021] Furthermore, a suction hood 6 is installed on the side and / or top of the baking station, the suction hood having a suction hood outlet pipe 61, the suction hood outlet pipe being connected to the rotor inlet 41.

[0022] The above-mentioned features of this invention can collect and treat harmful gases generated by the baking station accessories on the composite device, ensuring a good working environment.
