Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a waste gas treatment device for the production of environmentally friendly wet strength agents. Background Art

[0002] Wet strength agents are primarily used in the papermaking industry, with PAE being the primary wet strength agent. Numerous manufacturers operate on a small scale, but urea, a raw material, must be added to their reactors. While the addition of urea and the subsequent cooling process ensure high product quality, the wet strength agent production process releases significant amounts of ammonia. To prevent environmental pollution, this gas is typically removed through waste gas treatment equipment.

[0003] Since ammonia is easily soluble in water, existing ammonia treatment equipment usually draws ammonia into an exhaust gas treatment tank and sprays the ammonia contained in the air through a spraying device. The ammonia is only carried away by the water flow for fusion. The fusion of ammonia and water takes a long time, which reduces the fusion efficiency of ammonia and water, resulting in a decrease in the treatment efficiency of the treatment equipment for ammonia.

[0004] According to the announcement number: CN209519563U, a waste gas treatment device for wet strength agent processing includes a wet strength agent reactor and an exhaust gas treatment device. The exhaust gas treatment device includes a top conical top cover and a bottom collection tower. A water storage tank is fixed to the outer wall of the bottom collection tower. A booster water pump is fixed to the water storage tank. Water nozzles are evenly fixed on the inner wall of the top conical top cover. The top conical top cover is also provided with an exhaust gas discharge interface. The exhaust gas treatment device also includes a combustion chamber and a filter chamber. An electronic igniter and an external oxygen input pipe are fixed in the combustion chamber. The top of the combustion chamber is connected to the filter chamber via an exhaust conduit. A partition layer, an activated carbon adsorption layer, a barrier layer, and a breathable and waterproof membrane layer are fixed in sequence in the filter chamber. The utility model has a reasonable structural arrangement. Most of the ammonia in the exhaust gas can be dissolved in water and removed. A small amount of ammonia is filtered and discharged after combustion, which is beneficial to reducing impurities in the exhaust gas. It has strong applicability and good practicality.

[0005] According to the waste gas treatment equipment introduced above, the ammonia contained in the air is sprayed by the spraying equipment, and the ammonia is only carried away by the water flow for fusion. It takes a long time for the ammonia and water to fuse, which reduces the fusion efficiency of ammonia and water, resulting in a decrease in the treatment efficiency of the treatment equipment for ammonia. Therefore, we need to propose an environmentally friendly waste gas treatment device for wet strength agent production. Utility Model Content
