A sintering machine flue gas treatment device based on a decarburization process

Abstract

This utility model discloses a sintering machine flue gas treatment device based on decarburization technology, belonging to the field of flue gas treatment technology. The device includes a treatment tank with a treatment mechanism inside and a filtration mechanism on the outer wall. The treatment mechanism includes a treatment section and a control section. The treatment section includes a liquid pump and a connecting box. The technical advantage is that the treatment mechanism uses the liquid pump to deliver ammonia water to the connecting box, where it is atomized and sprayed out through an atomizing nozzle. Simultaneously, a servo motor drives the connecting pipe, connecting box, and agitator plate to rotate via belt drive. The agitator plate stirs the flue gas and atomized ammonia water in the treatment tank, enhancing the contact area and mixing uniformity, effectively improving the efficiency of desulfurization and dioxin removal reactions. The decarburization reactor works in conjunction with the treatment tank, combining the decarburization process with the preceding desulfurization and dioxin removal processes, thus improving the overall flue gas treatment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a sintering machine flue gas treatment device based on decarburization process. Background Technology

[0002] A sintering machine is a specialized piece of equipment used in the sintering process, often referred to as a sintering furnace. It is the main equipment in the sintering process and is primarily suitable for large and medium-sized sintering plants for sintering iron ore powder. It can sinter concentrates and rich ore powders of different compositions and particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. In addition, it is widely used in the ceramics, metal, and plastics industries to manufacture durable, high-strength products such as gears, bearings, and electrical components. The flue gas generated during the operation of the sintering machine contains a large amount of pollutants such as carbon dioxide, sulfur dioxide, and dioxins, which pose a serious threat to the environment and human health. The flue gas needs to be treated before it is emitted. In existing sintering machine flue gas treatment devices, the treatment liquid does not have sufficient contact with the flue gas. The treatment liquid is mostly sprayed statically or in a single direction, making it difficult to mix evenly with the flue gas. This results in low efficiency of desulfurization, dioxin removal, and other reactions, and unsatisfactory pollutant removal. Therefore, a sintering machine flue gas treatment device based on decarbonization process is proposed. Utility Model Content

[0015] In operation, when treating the flue gas from the sintering machine, the flue gas is first initially filtered by the filter mechanism 3. The flue gas generated by the sintering machine enters the filter box 32 through the inlet pipe 36. The filter plate 35 on the inner wall of the mounting frame 33 filters out particulate matter and other impurities in the flue gas. The filtered flue gas enters the treatment tank 1 through the gas delivery pipe 31. The impurities produced by filtration fall into the collection frame 37 through the material leakage trough on the bottom of the filter box 32.

Subsequently, the treatment unit 2 treats the flue gas entering the treatment tank 1 for decarbonization and other processes. The liquid pump 21 operates, delivering ammonia water through its outlet to the connecting pipe 212, which then enters the connecting box 23. Finally, the ammonia water is atomized by two sets of atomizing nozzles 24 and sprayed out, fully contacting the flue gas in the treatment tank 1 to achieve desulfurization and dioxin removal. Simultaneously, the servo motor 22 starts, its output end driving the connecting pipe 212 to rotate via the pulley 210 and belt. The connecting pipe 212 drives the connecting box 23 to rotate, and the connecting rod 26 on the outer wall of the connecting box 23 drives the stirring plate 25 to rotate. The stirring plate 25 stirs the flue gas and atomized ammonia water in the treatment tank 1, further promoting the mixing reaction and improving the desulfurization and dioxin removal effect. The annular groove on the inner wall of the connecting pipe 212 cooperates with the limiting ring 211 on the outer wall of the liquid pump 21's outlet to ensure that the liquid pump 21's outlet can stably deliver the treatment liquid to the connecting pipe 212 while it rotates. After the treatment is completed, the decarbonization reactor 29 operates to extract the treated gas from the treatment tank 1. When the gas enters the decarbonization reactor 29, it can be decarbonized. The waste liquid in the treatment tank 1 can be discharged through the drain pipe 27. The valve on the outer wall of the drain pipe 27 can control the discharge.
