炉体15排出的废气与负离子风混合后，废气内部的颗粒经过聚集成团变大，然后提高了沸石分子筛20对废气颗粒的过滤效果，然后经过沸石分子筛20过滤后的废气排入第一安装腔2中，在此过程中，废气的热量对沸石分子筛20进行加热，使沸石分子筛20温度升高，同时安装轴21转动驱动减速箱19的输入端转动，通过内部齿轮组减小输出扭矩，降低输出轴转速，减速箱19的输出轴驱动安装盘18转动，更换沸石分子筛20的位置。After the exhaust gas discharged from the furnace body 15 is mixed with the negative ion wind, the particles inside the exhaust gas are aggregated into clusters and become larger, thereby improving the filtering effect of the zeolite molecular sieve 20 on the exhaust gas particles, and then the exhaust gas filtered by the zeolite molecular sieve 20 is discharged into the first installation In the cavity 2, during this process, the heat of the exhaust gas heats the zeolite molecular sieve 20, causing the temperature of the zeolite molecular sieve 20 to rise. At the same time, the installation shaft 21 rotates to drive the input end of the reduction box 19 to rotate, and the output torque is reduced through the internal gear set. The output shaft speed is reduced, the output shaft of the reduction box 19 drives the mounting plate 18 to rotate, and the position of the zeolite molecular sieve 20 is replaced.
如图2和图7所示，废气从第一气管17和第二气管22进入第一安装腔2中，而上述从第二安装箱47中换热后排出的气体则从第二风管351中吹向位于上方的沸石分子筛20，对沸石分子筛20进行反冲，将堵在沸石分子筛20上的废气颗粒反冲掉，同时，由于反冲的气体低于排出的废气，因此，可以达到对沸石分子筛20进行降温，通过对沸石分子筛20进行反冲和降温，可以减少废气中的含污物质对设备的腐蚀和损坏，提高设备的使用寿命。As shown in FIGS. 2 and 7 , the exhaust gas enters the first installation cavity 2 from the first air pipe 17 and the second air pipe 22 , and the gas discharged after heat exchange from the second installation box 47 is discharged from the second air pipe 351 The zeolite molecular sieve 20 is blown upward to backflush the zeolite molecular sieve 20 to backflush away the waste gas particles blocked on the zeolite molecular sieve 20. At the same time, since the backflush gas is lower than the discharged waste gas, it is possible to achieve The zeolite molecular sieve 20 is used for cooling. By backflushing and cooling the zeolite molecular sieve 20, corrosion and damage to the equipment caused by pollutants in the exhaust gas can be reduced, and the service life of the equipment can be increased.
同时，对沸石分子筛20进行反冲时，会将沸石分子筛20内部吸附的少量二氧化硫、二氧化碳、氢气等反冲进入炉体15内部，其中，At the same time, when the zeolite molecular sieve 20 is recoiled, a small amount of sulfur dioxide, carbon dioxide, hydrogen, etc. adsorbed inside the zeolite molecular sieve 20 will be recoiled into the furnace body 15, where,
在高炉冶炼过程中，由于炉渣的熔点比铁的熔点高，因此必须加入足够量的熔剂来降低渣的熔点，以便顺利地排除炉渣，二氧化硫可以参与到渣的还原中，生成硫化物，降低渣的熔点，促进炉渣的排除，提高高炉生产的效率，且在炼钢生产过程中，二氧化硫可以参与到钢中的还原过程中，将钢中的硫化物还原为S和H2S，从而降低钢中的硫含量，提高钢的品质，且二氧化硫可以作为还原剂参与到炼钢中的化学反应中，促进炼钢过程的进行，例如，二氧化硫可以与一氧化碳反应生成二氧化碳和硫，参与到颗粒物还原反应和浸渣等化学反应中，推动炼钢过程的进行二氧化硫是炼钢氧化还原反应的重要产物之一，通过添加铁废料和含碳端料等炼钢原料等方式加入炉体15中，反冲进入炉体15内的二氧化硫可以与炉内应有的其他反应气体结合生成硫化氢、三氧化硫等化合物，参与到反应中，促进炼钢生产过程；反冲进入炉体15内的二氧化碳量有助于炼钢过程中产生CO，促进颗粒物还原反应，同时会参与到浸渣等化学反应中，氢气则是炼钢过程中一种重要的还原剂，其可以与CO反应生成CH4和H2O，同时也可与铁氧化物发生还原反应生成铁，促进炼钢过程的进行。During the blast furnace smelting process, since the melting point of slag is higher than that of iron, a sufficient amount of flux must be added to lower the melting point of the slag so that the slag can be removed smoothly. Sulfur dioxide can participate in the reduction of the slag, generate sulfides, and reduce the slag content. melting point, promotes the removal of slag, and improves the efficiency of blast furnace production. In the steelmaking process, sulfur dioxide can participate in the reduction process of steel, reducing the sulfides in the steel to S and H2S, thereby reducing the Sulfur content can improve the quality of steel, and sulfur dioxide can be used as a reducing agent to participate in chemical reactions in steelmaking, promoting the steelmaking process. For example, sulfur dioxide can react with carbon monoxide to generate carbon dioxide and sulfur, and participate in particulate matter reduction reactions and leaching. In chemical reactions such as slag, sulfur dioxide is one of the important products of the redox reaction of steelmaking to promote the steelmaking process. It is added to the furnace body 15 by adding steelmaking raw materials such as iron scrap and carbon-containing end materials, and is backflushed into the furnace. The sulfur dioxide in the furnace body 15 can be combined with other reaction gases in the furnace to generate hydrogen sulfide, sulfur trioxide and other compounds, which participate in the reaction and promote the steelmaking production process; the amount of carbon dioxide that recoils into the furnace body 15 is helpful to the steelmaking process. CO is produced during the steelmaking process, which promotes the reduction reaction of particulate matter and participates in chemical reactions such as slag leaching. Hydrogen is an important reducing agent in the steelmaking process. It can react with CO to generate CH4 and H2O, and can also react with CO to form CH4 and H2O. Iron oxides undergo a reduction reaction to produce iron, which promotes the steelmaking process.

The outer wall of the installation pipe 7 is fixedly connected to a wing plate 13: fixedly connected to the fourth installation cavity. 5. The fixed rod 10 at the bottom extends into the installation tube 7 and is rotationally connected to the installation tube 7; a plurality of sets of vibrating plates 12 are fixedly connected to the inner wall of the installation tube 7; and are fixedly connected to the fixed rod 10 for use. Toggle the bump 11 of the vibrating plate 12, and the wing plate 13 is tilted and fixedly connected to the side wall of the installation tube 7. The wing plate 13 is fixedly connected with a plurality of sets of inclined water holes 14, and also includes a heat storage ceramic 6. The thermal ceramic 6 is fixedly connected to the top of the fourth installation cavity 5, and the top of the thermal storage ceramic 6 extends into the third installation cavity 4.

经过颗粒去除的废气进入安装管7中，然后流动到蜗管8中，最后通过倾斜设置的排气管9排入废气处理剂中，在气流与液态废气处理剂的作用下，安装管7带动翼板13转动，废水处理剂穿过斜切设置的通水孔14，安装管7转动的同时带动振动片12转动，振动片12转动的过程中与凸块11配合产生振动，振动通过安装管7传递到废水处理剂中，从而增加废气与废水处理剂的接触面积，促进了废气处理剂的吸收和分解，提高了废气处理的效果，其中，通过蓄热陶瓷6将废气的热量传递到第三安装腔4中的水中，对水进行加热，使水升温沸腾蒸发形成水蒸气，利用水蒸气产生动力向炉体15内注入空气，促进炼钢。The exhaust gas after particle removal enters the installation pipe 7, then flows into the scroll tube 8, and is finally discharged into the exhaust gas treatment agent through the inclined exhaust pipe 9. Under the action of the air flow and the liquid exhaust gas treatment agent, the installation pipe 7 drives The wing plate 13 rotates, and the wastewater treatment agent passes through the beveled water hole 14. When the installation tube 7 rotates, it drives the vibration plate 12 to rotate. During the rotation, the vibration plate 12 cooperates with the bump 11 to generate vibration, and the vibration passes through the installation tube. 7 is transferred to the wastewater treatment agent, thereby increasing the contact area between the waste gas and the wastewater treatment agent, promoting the absorption and decomposition of the waste gas treatment agent, and improving the effect of waste gas treatment. Among them, the heat of the waste gas is transferred to the third through the heat storage ceramic 6 The water in the three installation chambers 4 is heated, causing the water to heat up, boil and evaporate to form water vapor. The water vapor is used to generate power to inject air into the furnace body 15 to promote steelmaking.
参照图2，储存部包括储物盒44，储物盒44内滑动连接有接料盒45，储物盒44的顶部固定连接有环形箱41，环形箱41顶部的进气端与第五风管40相连，环形箱41的侧壁固定连接有与炉体15相连的气管，气管上固定连接有过滤网43，储存部还包括转动连接在环形箱41内的中转盒42，中转盒42上开设有多组储存槽，储存槽内固定连接有毛刷46。Referring to Figure 2, the storage part includes a storage box 44. A material receiving box 45 is slidably connected in the storage box 44. An annular box 41 is fixedly connected to the top of the storage box 44. The air inlet end of the top of the annular box 41 is connected to the fifth air outlet. The pipes 40 are connected, and the side wall of the annular box 41 is fixedly connected with an air pipe connected to the furnace body 15. The air pipe is fixedly connected with a filter 43. The storage part also includes a transfer box 42 that is rotatably connected in the annular box 41. The transfer box 42 is Multiple sets of storage tanks are provided, and brushes 46 are fixedly connected in the storage tanks.
反冲的气体进入储存槽中，通过槽壁推动中转盒42转动，转动到气管出后，通过气管排入炉体15内部，排入之前，通过过滤网43过滤掉颗粒物，将颗粒物拦截在储存槽中，同时，毛刷46对过滤网43进行清洁，大部分相应的储存槽转动到底部后，在重力的作用下，颗粒团落到接料盒45中储存。The backflushed gas enters the storage tank and pushes the transfer box 42 to rotate through the tank wall. After rotating until the air pipe comes out, it is discharged into the furnace body 15 through the air pipe. Before being discharged, the particulate matter is filtered out through the filter screen 43 and intercepted in the storage tank. In the tank, at the same time, the brush 46 cleans the filter screen 43. After most of the corresponding storage tanks rotate to the bottom, the particles fall into the receiving box 45 for storage under the action of gravity.
