Мокрый пылеуловитель содержит корпус 1 с патрубками 2 подвода и 3 отвода газов, снизу к которому прикреп- ^,5лены основной 4 и дополнительный 5 шламосборники с разделительной перегородкой 6, а внутри установлены за патрубком 2 соответственно по направлению потока газов основной / и дополнительный 8 роторы, отличающиеся · различным шагом установки дисков и имеющие приводы 9, которые снабжены передачей 10 между валами роторов и ₂₅приводов. В патрубке 2 установлены пластины 11 с утолщениями 12 на концах. К корпусу 1 прикреплены подпиточное устройство 13 с трубопроводом 14 и щелевые каналы 15 для подачи воды.The wet dust collector contains a housing 1 with nozzles 2 for supplying and 3 exhaust gases, from the bottom to which are attached ^{, 5} main lenders 4 and additional 5 sludge collectors with a dividing wall 6, and inside are installed behind the nozzle 2, respectively, in the direction of gas flow, the main / and additional 8 rotors characterized by different disk installation steps and having drives 9, which are equipped with a transmission 10 between the rotor shafts and ₂₅ drives. In the pipe 2, plates 11 are installed with thickenings 12 at the ends. Attached to the housing 1 is a make-up device 13 with a pipe 14 and slotted channels 15 for supplying water.

Диски роторов аппарата изготавливаются из материала с хорошо смачиваемой поверхностью, шаг их установки для первого ротора равен 0,060,012 диаметра дисков, а для допол- ³⁵нительного ротора - вдвое меньше. Причем для дополнительной турбулизации потока пластины 11 во входном патрубке 2 установлены напротив середины каждого зазора между дисками ⁴⁰ротора 7 и снабжены утолщениями 12 на концах, при этом четные диски дополнительного ротора 8 размещены в створе дисков основного ротора 7, а нечетные - в створе пластин 11. ⁴³ The rotor disks of the apparatus are made of material with a well-wettable surface, the step of their installation for the first rotor is 0.060.012 of the diameter of the disks, and for an additional ³⁵ rotor - half as much. Moreover, for additional turbulization of the flow of the plate 11 in the inlet pipe 2 is installed opposite the middle of each gap between the disks ^{40 of the} rotor 7 and provided with bulges 12 at the ends, while the even disks of the additional rotor 8 are located in the alignment of the disks of the main rotor 7, and the odd ones are in the alignment of the plates 11 . ⁴³

Мокрый пылеуловитель работает следующим образом.Wet dust collector operates as follows.

Запыленные газы поступают в корпус 1 через патрубок 2, проходя последовательно в зазоры между пластина- 50 ми 11 и смоченными вращающимися дисками 16 ротора 7 и дисками 17 дополнительного ротора 8, очищаются от пыли или аэрозолей при контакте с пленкой жидкости и выводятся в атмосферу 55 через патрубок 3. Роторы 7 и 8 вращаются по направлению потока газов за счет приводов 9, что обеспечивает постоянное их смачивание и смыв с них уловленных частиц пыли в шламосборники 4 и 5.Dusty gases enter the housing 1 through the nozzle 2, passing successively into the gaps between the plates 50 and 11 and the wetted rotating disks 16 of the rotor 7 and the disks 17 of the additional rotor 8, are cleaned of dust or aerosols in contact with the liquid film and are released into the atmosphere 55 through branch pipe 3. The rotors 7 and 8 rotate in the direction of the gas flow due to the actuators 9, which ensures their constant wetting and flushing of the captured dust particles from them into the sludge collectors 4 and 5.

Поддержание заданного уровня воды обеспечивается за счет подпиточного устройства 13 с трубопроводом 14. Дополнительный смыв частиц пьши с дисков производится водой, периодически подаваемой через щелевые каналы 15.Maintaining a predetermined water level is ensured by a make-up device 13 with a pipe 14. An additional flushing of the particles of the drink from the disks is made by water periodically supplied through the slotted channels 15.

За счет перегородки 6 происходит разделение крупных и мелких частиц и предотвращается волнообразование между роторами 7 и 8. Наличие на входе потока пластин 11 обеспечивает турбулизацию потока газов и направление их на смоченные поверхности дисков. Уменьшение вдвое шага установки дисков дополнительного ротора 8 и их смещение относительно дисков первого ротора 7 так, что его четные диски смонтированы с ними в створе, а нечетные - посредине их зазоров, способствуют улавливанию более мелких частиц пьши. Причем первичный процесс смачивания частиц, их коагуляции и улавливания в роторе 7, затем протекает более интенсивно и эффективно за счет большей турбулизации пленки жидкости в узких каналах дополнительного ротора 8.Due to the partition 6, large and small particles are separated and wave formation between the rotors 7 and 8 is prevented. The presence of the plates 11 at the inlet of the stream provides turbulence of the gas stream and their direction to the wetted surfaces of the disks. The halving of the installation step of the disks of the additional rotor 8 and their displacement relative to the disks of the first rotor 7 so that its even disks are mounted with them in alignment, and the odd disks in the middle of their gaps, contribute to the capture of smaller particles of the drink. Moreover, the primary process of wetting the particles, their coagulation and trapping in the rotor 7, then proceeds more intensively and efficiently due to greater turbulence of the liquid film in the narrow channels of the additional rotor 8.
