Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a drying machine. Background Art

[0002] Dryer is a commonly used industrial equipment. Its main function is to dry materials with moisture through hot air to remove moisture. Dryers can be divided into many types according to different drying methods, such as fluidized bed dryer, drum dryer, hot air dryer, vacuum dryer, etc.

[0003] In the textile industry, dryers are widely used in the production of textiles such as cloth, yarn, fiber, etc. These materials need to be dried before further processing during the production process such as dyeing and washing. Therefore, dryers play a very important role in the textile industry.

[0004] At present, existing fiber dryers all use high-temperature and high-humidity hot air for drying to remove moisture from the fiber so that the fiber can be dried while maintaining its quality. Although this drying mode can achieve a certain drying effect, the fuels used in the hot air drying process, such as coal and oil, will produce a large amount of harmful gases and dust particles such as carbon dioxide, nitrogen oxides, and smoke during the combustion process. These pollutants are discharged into the atmosphere, causing air pollution. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-4 As shown, a dryer includes a body 1, a hollow drying chamber 2 is opened in the body 1, and the drying chamber 2 is connected to a sewage pipe; a waste gas processor is arranged at the outlet of the sewage pipe, and is used for purifying the discharged sewage. By setting the waste gas processor, the harmful gas discharged by the hot air dryer can be effectively purified to prevent the discharge of sewage into the atmosphere, thereby effectively protecting the factory environment from pollution.

[0028] like Figure 5-6 As shown, the exhaust gas device includes a treatment box 3, and an air inlet 4 and an exhaust port 5 are respectively provided at both ends of the treatment box 3. A connector 6 is provided on one side of the air inlet 4, and the connector 6 is used to connect with a sewage pipe. A sealing ring 7 is provided at the connection between the connector 6 and the sewage pipe. Through this arrangement, it is ensured that the exhaust gas will not escape before entering the exhaust gas treatment device, thereby avoiding environmental pollution and ensuring the normal operation of the exhaust gas treatment device.

[0029] Furthermore, a plurality of purification chambers 8 are provided in the processing box body 3, and a mounting plate 9 is provided between each purification chamber 8. A mounting groove is provided in the mounting plate 9, and the mounting groove is used to place a filter plate 10. By providing multiple layers of filter plates, multi-stage filtration is achieved to ensure that impurities, harmful gases and droplets in the exhaust gas can be fully separated and purified, thereby ensuring the exhaust gas purification effect.

[0030] Specifically, a filter cartridge 11 is arranged in the purification chamber 8, and a plurality of filter holes 12 are opened on the filter cartridge 11. There may be some harmful gases in the exhaust gas, such as ammonia, sulfur dioxide, chlorine, etc. The exhaust gas is subjected to multi-stage filtration by the filter cartridge 11, so that the pollutants in the exhaust gas can be completely removed, which can greatly reduce the exhaust gas emission concentration and meet the environmental protection standards. The surface area of ​​the filter cartridge 11 is relatively large. After the exhaust gas passes through the filter cartridge 11, the area in contact with the surface of the filter cartridge 11 increases, so that the pollutants in the exhaust gas are easier to be adsorbed and removed.

[0031] Specifically, the filter plate is one of an activated carbon filter plate 10 or a HEPA filter plate 10, and photocatalyst particles are attached to the filter plate. The activated carbon filter plate 10 is a common filter element and an important component of the exhaust gas treatment device. Its main function is to adsorb and purify pollutants such as organic matter, odor, toxic and harmful gases in the exhaust gas. Specifically, there may be many organic substances in the exhaust gas, such as benzene substances, aldehyde compounds, phenolic compounds, etc. The activated carbon filter plate 10 uses its high specific surface area and pore structure to adsorb these organic substances, thereby purifying the exhaust gas; there may be malodor or irritating taste in the exhaust gas, such as various industrial exhaust gases, garbage incineration exhaust gases, etc. The activated carbon filter plate 10 uses its adsorption capacity for harmful gases such as hydrogen sulfide and ammonia to remove the odor in the exhaust gas; the activated carbon filter plate 10 can convert harmful gases into harmless gases through adsorption reactions, thereby achieving the purpose of purification; similarly, the activated carbon filter plate 10 is used in combination with the filter cartridge 11 to form a multi-stage filtration system to improve the efficiency and purification effect of exhaust gas treatment.

[0032] In this embodiment, an ultraviolet lamp 13 is provided on the mounting plate 9 for irradiating the photocatalyst particles on the filter plate. The photocatalyst is a substance that does not change itself under the irradiation of light but can promote chemical reactions. The photocatalyst can activate the oxygen and moisture adsorbed on the surface of the material under the irradiation of light, generate its own hydroxyl groups and active oxygen with extremely strong oxidizing ability, and cause an oxidation reaction to completely decompose the VOC in the air into carbon dioxide and water.

[0033] In addition, photocatalyst is synthesized from multiple catalysts, and its biggest feature is that it strongly absorbs ultraviolet rays in light. Ultraviolet rays and other rays themselves are a kind of energy. After absorbing ultraviolet rays, the photocatalyst's molecules move violently and become excited, but the substance itself remains unchanged. When there are odorous substances in the air (formaldehyde, acetic acid, ammonia, etc.), when passing through the photocatalyst network, they collide with the excited photocatalyst, absorb part of the energy, and also become excited. The molecules move violently and unstable, and a series of chemical reactions occur, which are called photodissociation reactions. The odorous substances are converted into odorless substances, thereby purifying the exhaust gas.

[0034] Furthermore, a winding rack 14 is provided in the machine body 1 , and a hot air generating device is provided on one side of the winding rack 14 .

[0035] Specifically, a water inlet nozzle 15 is also provided on the processing box 3, and a liquid inlet pipe 16 is connected to one side of the water inlet nozzle 15. By spraying water into the exhaust gas processor, the heat in the exhaust gas is absorbed and water vapor is formed, thereby achieving the purpose of cooling and purifying the exhaust gas, thereby improving the exhaust gas treatment efficiency.

[0036] It should be noted that the utility model is a dryer. When in use, the fiber is wound into the winding rack 14, and the hot air generating device is started so that the fiber is quickly dried under the action of high-temperature hot air. At the same time, the waste gas generated during heating will enter the waste gas collector through the drain pipe, and will be filtered through the combination of the filter plate 10 and the filter cartridge 11 to achieve a high degree of purification of the waste gas. By spraying water into the waste gas processor, the heat in the waste gas is absorbed and water vapor is formed, thereby achieving the purpose of cooling and purifying the waste gas, further improving the waste gas treatment efficiency, and effectively protecting the factory air from pollution.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
