Description

Technical Field

[0001] The utility model belongs to the field of washing powder drying, and particularly relates to a water removal and particle reduction device for treating washing powder drying waste gas. Background Art

[0002] In the laundry detergent production process, the drying stage is one of the main stages of waste gas generation. This process involves heating and drying the detergent raw materials or finished products, generating large amounts of steam and volatile organic compounds (VOCs). The exhaust gas from laundry detergent drying is complex, including water vapor, VOCs, and dust. Furthermore, it may contain small amounts of inorganic gases such as sulfur dioxide (SO2) and nitrogen oxides (NOx), which are harmful to humans and the environment. To address the characteristics of laundry detergent drying exhaust gas, cooling and dust removal methods are employed. Cooling the high-temperature exhaust gas reduces its temperature and humidity, facilitating subsequent processing and removing detergent particles from the exhaust gas. In practice, many laundry detergent manufacturers employ a comprehensive treatment solution combining "pretreatment + activated carbon adsorption + catalytic combustion." This multi-stage cascade technology strategy treats the exhaust gas to ensure that emissions meet national environmental standards. With increasingly stringent environmental regulations and continuous technological advancements, more efficient and environmentally friendly waste gas treatment technologies will be applied to the treatment of laundry detergent drying exhaust gas in the future.

[0003] In the existing technology, the particulate matter content of the drying exhaust gas discharged after the cyclone dust removal is high and the temperature is relatively high. Conventional heat exchange equipment is prone to blockage, and the washing powder is easy to harden and difficult to dissolve. At the same time, the high-temperature and high-humidity exhaust gas directly entering the plasma equipment is easy to burn, and the precipitation effect of moisture and particulate matter is poor, which cannot meet the requirements and the equipment operating efficiency is low. Moreover, dust is easily accumulated inside the heat exchange equipment. Summary of the Invention

[0004] In response to the problems in the related technology, the utility model proposes a dehydration and particle reduction device for treating laundry detergent drying waste gas. An air-to-air heat exchanger and a steam-to-water heat exchanger are added in parallel behind the cyclone separator. The gas is dehydrated and the laundry detergent particles are removed through two heat exchanges. At the same time, secondary cooling is used to prevent high-temperature and high-humidity waste gas from directly entering the plasma equipment, thereby avoiding burning the equipment.

[0005] The utility model is achieved in this way:
