Flue gas emission method and exhaust chimney
The flue gas emission treatment method comprises the following steps: enabling flue gas to sequentially pass through a sieve plate and a water seal layer with a certain thickness formed on the sieve plate and then to be discharged into the atmosphere, and further comprises a step of eliminating liquid drops in the flue gas passing through the water seal layer, the method further comprises the step of leaching the flue gas before penetrating through the sieve plate and/or leaching the flue gas after penetrating through the water seal layer, the relative pressure of the flue gas before penetrating through the sieve plate is not lower than 50 Pa, and the flow velocity is not lower than 1 m/s. The invention further discloses an exhaust chimney, the exhaust chimney comprises a smoke exhaust pipeline, the smoke exhaust pipeline limits the flowing path of smoke, a sieve plate with a plurality of sieve holes is arranged in the smoke exhaust pipeline, and a water seal layer covering the top surface of the sieve plate is formed on the top surface of each sieve plate. The exhaust chimney disclosed by the invention is simple in structure, and an existing exhaust chimney can be directly modified on site, so that the investment of conveying equipment and treatment equipment can be correspondingly reduced, the environment-friendly treatment operation cost is saved, and the energy consumption is reduced.
一种烟气排放处理方法，包括：使烟气依次穿过筛板和筛板上形成的厚度一定的水封层再被排放到大气中，还包括将穿过所述水封层的烟气中的液滴消除的步骤，还包括对穿过筛板前的烟气进行淋洗和/或对穿过水封层后的烟气进行淋洗的步骤，所述烟气穿过筛板前的相对压力不低于50Pa，流速不低于1m/s。本发明还公开了一种排气囱，包括排烟管道，所述排烟管道限定烟气的流动路径，所述排烟管道中设置具有多个筛孔的筛板，所述筛板顶面均形成有覆盖筛板顶面的水封层。本发明公开的排气囱结构简单，可以直接对现有的排气囱作就地改造，也就可以相应减少输送设备和处理设备的投入，节约环保治理运行成本，降低能耗。
