Technical Field

[0001] This utility model relates to an odor removal device for automotive interior materials, specifically a device for reducing odor and VOCs in automotive interior composite fabrics. Background Technology

[0002] Automotive interior composite fabrics are typically made by layering and laminating an outer layer, a sponge, and a base fabric. Lamination processes include flame lamination and adhesive lamination. The sponge and adhesives are the main sources of VOCs and odors.

[0003] Traditional methods for reducing VOCs include high-temperature baking and replacing materials with environmentally friendly alternatives. High-temperature baking is energy-intensive, has limited VOC removal efficiency, and is difficult to treat in the exhaust, potentially leading to other environmental problems. Replacing materials with environmentally friendly alternatives can effectively reduce product temperature and VOCs, but these materials are expensive and have limited physical and chemical properties, hindering their large-scale application.

[0004] In addition, the deodorization devices used in existing technologies are relatively complex in structure and expensive. Utility Model Content

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0017] See Figure 1 The device for reducing odor and VOC in automotive interior composite fabrics provided by this utility model includes a solvent mixing component, a drying oven system, a hot air conveying system, and an air suction system.

[0018] The composite fabric to be reduced in odor and VOC is placed in the drying oven system. The solvent mixing component delivers the corresponding proportion of mixed solvent to the drying oven system and sprays it onto the composite fabric. Then, the hot air conveying system delivers hot air to the drying oven system to dry the composite fabric and remove VOCs from the automotive interior composite fabric. The air extraction system extracts the VOCs in the drying oven system for emission and recycling.

[0019] The solvent mixing component is used to mix water and organic solvents in the required proportions to form a mixed solvent that can remove VOCs from automotive interior composite fabrics, and then deliver it into the drying oven system.

[0020] The solvent mixing assembly includes a water tank 1, an organic solvent tank 2, an organic solvent metering pump 3, a water metering pump 4, and a pipeline mixer 5.

[0021] Water metering pump 4 is connected to water tank 1 and is used to extract water from water tank 1 and deliver it to pipeline mixer 5 under pressure.

[0022] The organic solvent metering pump 3 is connected to the organic solvent tank 2 and is used to extract the organic solvent stored in the organic solvent tank 2 and deliver it to the pipeline mixer 5 under pressure.

[0023] The pipeline mixer 5 is connected to the organic solvent metering pump 3 and the water metering pump 4 respectively, and is used to pressurize and mix the water and organic solvent delivered by the water metering pump 4 and the organic solvent metering pump 3 respectively to form a mixed solvent.

[0024] Since the water metering pump 4 and the organic solvent metering pump 3 can control the flow rate, the ratio of water and organic solvent in the pipeline mixer 5 can be controlled by the organic solvent metering pump 3 and the water metering pump 4, thereby meeting different needs.

[0025] The drying oven system, which provides a sealed environment for automotive interior composite fabrics and is designed to reduce odors and VOCs, includes a sealed cavity 6, within which are an unwinding system 6.1, a roller conveyor 6.2, several air inlets 6.3, several solvent nozzles 6.4, several hot air nozzles 6.5, and a winding system 6.6.

[0026] The unwinding system 6.1 is connected to the winding system 6.6 via the roller conveyor 6.2. The rolled automotive interior composite fabric is flattened at the unwinding system 6.1, conveyed forward by the roller conveyor 6.2, and then wound up by the winding system 6.6.

[0027] The unwinding system 6.1, the roller conveyor 6.2, and the winding system 6.6 are conventional existing structures, and their specific implementation principles will not be elaborated here.

[0028] Several solvent nozzles 6.4 are connected to the pipeline mixer 5 through pipelines. Specifically, the solvent nozzles 6.4 can be located above the roller conveyor 6.2. The pipeline mixer 5 uniformly coats the surface of the automotive interior composite fabric moving on the roller conveyor 6.2 with a layer of mixed solvent through the solvent nozzles 6.4. The mixed solvent can react with the aldehydes in the automotive interior composite fabric to generate harmless compounds and water, thereby effectively reducing the content of aldehydes in VOCs.

[0029] Several hot air nozzles 6.5 are located on the roller conveyor 6.2 and are used to spray hot air to heat the automotive interior composite fabric and improve the reaction between the automotive interior composite fabric and the mixed solvent.

[0030] The hot air delivery system includes a heating heat exchanger 10 and an air supply fan 11. The air supply fan 11 is connected to the heating heat exchanger 10, and the heating heat exchanger 10 is connected to several hot air nozzles 6.5 respectively. The air outside the drying room system is powered by the air supply fan 11, and after being heated by the heating heat exchanger 10, it enters the hot air nozzles 6.5 to heat the composite fabric.

[0031] The air intake system includes an air intake fan 7, a refrigeration heat exchanger 8, and a heat pump system 9. The air intake fan 7 is connected to several air intake ports 6.3, and the heat pump system 9 is connected to the refrigeration heat exchanger 8.

[0032] The polluted air carrying solvent and VOC generated in the drying oven system is discharged from the drying oven system through the air intake 6.3 under the action of the air intake fan 7. After passing through the cooling heat exchanger 8, the temperature is reduced, and the solvent and VOC recondense into liquid, which can then be sent to the corresponding recovery system for processing.

[0033] The heat pump system 9 is used to provide energy for the refrigeration heat exchanger 8. The heat pump system 9 in this application can be connected to the refrigeration heat exchanger 8 and the heating heat exchanger 10 respectively. The heat pump system 9 provides the corresponding heat medium and cold medium for the heating heat exchanger 10 and the refrigeration heat exchanger 8. The heat pump system 9 can provide both heat source and cold source at the same time, and can be used for two purposes with high efficiency and low energy consumption.

[0034] The following is the detailed application process:

[0035] The automotive interior composite fabric is fixed at the unwinding system 6.1 and continuously flattened under the action of the roller conveyor 6.2. The flattened end is fixed at the winding system 6.6, realizing unwinding and winding at the same time.

[0036] The solvent can be an amino compound, with a water ratio of 1:4. After being mixed evenly at the pipe mixer 5, it is sprayed onto the surface of the composite fabric through the solvent nozzle 6.4. The diluted solvent reacts with the aldehydes in VOCs to generate harmless compounds and water, which can effectively reduce the content of aldehydes in VOCs.

[0037] The compressor of the heat pump system 9 operates, carrying the heat from the refrigeration heat exchanger 8 to the heating heat exchanger 10, thereby simultaneously cooling the refrigeration heat exchanger and heating the heating heat exchanger.

[0038] Air enters the heating heat exchanger 10 under the action of the air supply fan 11, and is then ejected from the hot air nozzle 6.5;

[0039] Stale air enters the duct through the air intake 6.3 and enters the refrigeration heat exchanger 8 under the drive of the air intake fan 7. The temperature decreases and the solvent carrying VOCs recondenses into liquid and enters the recovery system for processing.

[0040] The air supply fan 11 and the air intake fan 7 can form a circulating airflow, which can effectively remove benzene-related substances and reduce the content of benzene-related substances in VOCs.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
