Description

Technical Field

[0001] The utility model relates to the technical field of deacidification and deamination towers, in particular to an anti-blocking feeding structure of a deacidification and deamination tower. Background Art

[0002] The wastewater generated during coal gasification and coking contains a large amount of volatile acid gases (CO2, H2S, etc.), free ammonia, fixed ammonia (ammonium salts), phenols, etc. The purification and recycling of coal chemical wastewater must first remove the acid gases and ammonia dissolved in water before entering the subsequent dephenolization and biochemical treatment process. The inorganic salt content in coal chemical wastewater is high, and scaling is easy to occur during the acid gas removal process, resulting in a decrease in the reboiler heat transfer coefficient and even clogging of the heat exchange pipeline. The superheated steam consumption is large, the energy consumption is high, and the heating reboiler structure is complex, resulting in increased investment and operating costs.

[0003] A search revealed a Chinese patent document that discloses a direct steam-heated coal chemical wastewater stripping, deacidification, and deamination tower [Application Number: CN201710775630.X]. This tower comprises a heating unit with a conical air guide at its upper end. A water inlet conduit is located on one side of the upper end of the heating unit. A mesh panel is located in the middle of the heating unit, and an air inlet main is located below the mesh panel.

[0004] The deacidification and deammonification tower disclosed in this patent can not only preheat the coal chemical wastewater in advance, but also directly heat it with water vapor, making heating faster and reducing pipe blockage. However, during the deacidification and deammonification process, ammonia and carbon dioxide in the wastewater enter the gas phase from the liquid phase. During the distillation process, the condensed products of ammonia and carbon dioxide and the uncondensed portion can directly form solids. Such solids are easily retained at one end of the water inlet conduit with the water vapor, causing blockage of the water inlet conduit and other conditions that affect the flow of wastewater into the deacidification and deammonification tower. In addition, solids entering the interior of the water inlet conduit through the water pipe can also easily cause blockage of the water inlet conduit. Utility Model Content

[0029] Working principle: The staff injects the sewage into the interior of the treatment box 3 through the water injection pipe 13. At this time, the filter plate 73 on one side can perform preliminary filtration on the sewage. After the preliminary filtration, the sewage flows into the deacidification and deamination tower body 1 through the feed pipe 2. At this time, the deacidification and deamination tower body 1 can perform deacidification and deamination treatment on the sewage. This process is an existing mature technology and will not be described in detail here. The treated sewage forms water vapor, and the water vapor rises. The mesh plate 16 blocks the moisture therein, and the moisture flows back to the interior of the treatment box 3 through the water pipe 14. Some of the solid matter generated during the deacidification and deamination treatment can be filtered by the filter plate 73 on the other side. Filter, the filtered water source is re-injected into the interior of the deacidification and deamination tower body 1 through the connecting pipe 12 for deacidification and deamination treatment. Some solid matter generated in the deacidification and deamination process will remain at one end of the feed pipe 2 with the water vapor. At this time, the staff can first pull out the positioning rod 201, and then rotate the adjusting disk 202. At this time, the adjusting disk 202 drives the cleaning plate 19 to rotate through the rotating shaft 18. Based on this, the staff can adjust the state of the cleaning plate 19, and then the staff pushes the disc 172, and the cleaning plate 19 moves to clean the solid matter on the inner wall of the feed pipe 2, thereby reducing the problem of blockage at one end of the feed pipe 2.
