The new plastic grid filler technology developed and developed by Hangzhou Warner will be promoted
The China Petroleum and Chemical Industry Association and the China Nitrogen Fertilizer Industry Association recently held a GS-series new plastic grid packing technology appraisal meeting and application promotion meeting in Hangzhou. The GS-2 type-GS-5 series new type plastic grid packing (technique) passed this time was developed by Hangzhou Warner Tower Separation Engineering Co., Ltd., Zhejiang Juhua Co., Ltd. Synthetic Ammonia Plant and Ningxia Fengyou Chemical Co., Ltd. Co., Ltd. collaborates on application development. China Nitrogen Fertilizer Industry Association has recommended this new product and technology to the industry. In the production of ammonia and urea in China's medium-sized nitrogenous fertilizer plants and small chemical fertilizer plants, the vast majority use coal as the raw material, and its synthetic ammonia desulfurization system usually uses ADA atmospheric pressure to desulfurize the water gas and convert gas by pressure. However, with the development of science and technology, the original desulfurization process can no longer meet the production requirements. When sulfur is recovered, most of the fillers used in packed towers are filled with wooden lattices, which can easily cause the deposition of sulfur paste and cause tower blockage. As a result, the gas-liquid flow in the tower creates a biased flow and affects the mass transfer effect. The new PVC grid fillers (techniques) jointly developed by Hangzhou Warner Tower Separation Engineering Co., Ltd. and other units mainly use plastic plates as mass transfer elements. The plastic plates are perpendicular to the surface of the tower, and the resistance to gas rise and liquid drop is greatly reduced. Therefore, the stagnant deposition and blockage of dust-laden gas and dirty liquid in the tower are improved, which has the advantages of large circulation volume and strong anti-jamming capability. It is understood that the new filler technology used in the thickness of PVC board 4mm, the surface is smooth, and the thickness of the wooden lattice packing is 10-12mm, and the surface area of ​​the PVC grille filler is 20%-30% larger than the wooden lattice packing. At the same time, because the PVC board is relatively smooth, the sulfur paste is not easily deposited on the surface of the filler, and the gas and liquid inside the tower have a fixed flow path, so the sulfur will not deposit on the surface of the filler under the flow of the gas and liquid. According to reports, this new filler is made of PVC-B plates, rods, tubes after a certain processing technology, according to the diameter of the tower, the size of the hole to be assembled, welded. The industrial application results of Hangzhou Longshan Chemical Plant, Ningxia Fengyou Chemical Co., Ltd. and Zhejiang Juhua Co., Ltd. and other units have shown that the desulfurization efficiency can be increased by 5%-10%, and the purification pressure in the post-work section can be reduced; the system resistance can be reduced, and the The amount of compressor air pumping reduces the power consumption of the compressor; it can reduce the amount of solution circulation and reduce the power consumption of the solution pump; the service life is extended, and the overhaul workload is greatly reduced.
