对多排风点除尘零碎,应在各支管、除尘器和通风机入、出口管的直管段和排气烟囱气流颠簸处,设置风量、风压测定孔。在除尘器入、出口管以及需求测量粉尘浓度的支管直管段气流颠簸处,就设置直径不小于80mm的粉尘取样孔。凡设粉尘取样孔的地点,不再反复设置风量、风压测定孔。

For the dust collection of multiple exhaust points, air volume and air pressure measuring holes shall be set at the straight pipe section of the inlet and outlet pipes of each branch pipe, dust remover and ventilator, and at the places where the air flow of the exhaust chimney is bumpy. Dust sampling holes with a diameter of no less than 80mm shall be set at the inlet and outlet pipes of the dust remover and the turbulence of the air flow in the straight section of the branch pipe for measuring the dust concentration. Where dust sampling holes are set, air volume and air pressure measurement holes will not be set repeatedly.
依据实践需求并结合微操条件,除尘零碎可采用集中控制或与有关工艺设备联络锁。普通除尘零碎应在工艺设备开动此前启动,在工艺设备中止运转后封闭。自动化程度高的除尘零碎可将除尘零碎由气控制设备与相应的工艺设备实行顺序控制,便于微操人员控制,但此时及需求通风除尘设备机旁装设控制开关。
According to the practical requirements and combined with the micro operation conditions, the centralized control or contact lock with the relevant process equipment can be used for dust removal. The ordinary dust removal parts shall be started before the process equipment is started and closed after the process equipment is stopped. For the high degree of automation, the dust can be sequentially controlled by the gas control equipment and the corresponding process equipment, which is convenient for the micro operators to control. However, the control switch is installed beside the ventilation and dust removal equipment.
对大型除尘零碎,可依据详细状况设置测理风量、风压、温度和粉尘浓度等参数的仪表。
For large-scale dust removal, instruments for measuring air volume, air pressure, temperature, dust concentration and other parameters can be set according to the detailed conditions.
对大型集中除尘零碎,必要时可设置监控零碎,当排放参数超标时,收回报警信号。
For large-scale centralized dust removal, if necessary, monitoring can be set. When the emission parameters exceed the standard, the alarm signal can be recovered.
大中型除尘器应设计检测电源。
The detection power supply shall be designed for large and medium-sized dust collectors.

除尘零碎设计中,应思索留有一定的检修立体和空间、装置孔洞、吊挂设备、走台、梯子、人孔和照设备等,为施工、微操和检修发明必要的条件。
In the design of dust removal, a certain maintenance space, device holes, hanging equipment, walking platform, ladder, manhole and lighting equipment should be reserved, which is necessary for construction, micro operation and maintenance.
对大型集中除尘零碎,必要时能够设置机房、仪表微操室等,对零碎停止集中微操管理。
For the large-scale centralized dust removal, if necessary, the machine room and instrument micro operation room can be set up, and the centralized micro operation management for the debris can be stopped.
设备和管道穿过平台时,需预留孔洞,孔洞周围设高出平台的防为凸台,孔洞直径此管道直径大20-80mm管道穿平台处容易腐蚀,必要时可在防水凸台上加高的一段金属防水套管。
When the equipment and pipeline pass through the platform, holes shall be reserved. A boss shall be set around the hole which is higher than the platform. The diameter of the hole is 20-80mm. The place where the pipeline passes through the platform is easy to be corroded. If necessary, a section of metal waterproof casing can be added on the waterproof boss.
大、中型除尘器的空中应有检修电源和水源。
There shall be maintenance power supply and water source in the air of large and medium-sized dust collectors.
