  脱硫石膏烘干机电除尘用具有如下的优点:
  Desulphurization gypsum dryer electromechanical dust collector has the following advantages:
  1.除尘效率高,理论上可达<100%的任何效率。实践应用中可达99.99%以上。当然,除尘效率的选取应依据工艺设计及国度排放规范来决议。除尘效率越高,设备所占空间和投资费用越高,应当综合思索其可行性。
  1. Dust removal efficiency is high, which can theoretically reach any efficiency less than 100%. More than 99.99% can be applied in practice. Of course, the selection of dust removal efficiency should be based on process design and national emission standards. The higher the dust removal efficiency, the higher the space occupied by the equipment and the higher the investment cost, the feasibility should be considered comprehensively.
  2.适用于处置大烟气量的场所。对处置烟气量较小的场所,电除尘器处置单位烟气量的造价很高,随着烟气且的增大,脱硫石膏烘干机处置单位烟气量的造价急剧降落,对处置l0万m3/h烟气量的场所,其综合费用逐步低于袋收尘器,处置烟气量越大,其优势愈加明显。
  2. Suitable for places with large flue gas volume. For places with small flue gas volume, the cost of ESP unit flue gas volume is very high. With the increase of flue gas, the cost of desulfurization gypsum dryer unit flue gas volume drops sharply. For places with 100,000 m3/h flue gas volume, its comprehensive cost is gradually lower than that of bag filter. The larger the amount of flue gas is, the more obvious its advantages are.
  3.适用于烟气温度较高的场所。通常,脱硫石膏烘干机电除尘器处置烟气量温度<300℃己毫无障碍,对烟气温度>250一400℃的场所,电防尘器的造价并无明显变化。假如采取恰当措施,烟气温度还可进步至450℃以上,并已能禁受住更高的瞬时温度。
  3. Suitable for places with high smoke temperature. Usually, there is no obstacle for desulfurization gypsum drying electromechanical precipitator to dispose of flue gas volume temperature < 300 C. There is no obvious change in the cost of electrostatic precipitator for places with flue gas temperature > 250-400 C. If appropriate measures are taken, the flue gas temperature can also be increased to more than 450 C, and can withstand higher instantaneous temperature.
  4.搜集的粉尘颗粒粒径范围很广。粗颗粒显然更易于被捕集,关于小到0.1um颗径的微细颗粒多数状况下也能获得较好的除尘效率,在粒径范围很宽的状况下,还可增加一级预收尘而综合经济指标不会有所增加。
  4. The collected dust particles have a wide range of particle sizes. Coarse particles are obviously easier to be trapped. For most cases, fine particles with a diameter of less than 0.1um can also achieve better dust removal efficiency. In the case of a wide particle size range, the first-level pre-collection can be increased, while the comprehensive economic indicators will not increase.
  5.脱硫石膏烘干机电除尘器构造简单,气流速度低,压力损失小,干式清灰电除尘器压力损失大约为100一200Pa,湿式清灰电除尘的压力损失稍高些,通常为200一300Pa。

  5. Desulphurization gypsum drying electromechanical precipitator has simple structure, low airflow speed and low pressure loss. The pressure loss of dry dust-cleaning electrostatic precipitator is about 1001 200 Pa. The pressure loss of wet dust-cleaning electrostatic precipitator is slightly higher, usually 200-300 Pa.
  脱硫石膏烘干机对装配精度请求十分高,高精度装配可保证烘干产品的精度,如何完成呢?
  Desulphurization gypsum dryer requires very high assembly accuracy, high precision assembly can ensure the accuracy of drying products, how to complete it?
  详细的办法其实有许多种,经过归结可分为互换法、选配法、修配法和调整法四大类。而且,同一项装配精度,因采用的装配办法不同,其装配尺寸链的解算办法亦不相同。
  There are many detailed methods, which can be divided into four categories: exchange method, selection method, repair method and adjustment method. Moreover, the solution of assembly dimension chain is different for the same assembly accuracy because of different assembly methods.
  依据脱硫石膏烘干机产品的性能请求、构造特性、消费方式和消费条件等能够采用不同的办法。现分述如下:互换法即零件具有互换性,就是在脱硫石膏烘干机装配过程中,各相关零件不经任何选择、调整,装置后就能到达装配精度请求的一种办法。产品采用互换装配法时,装配精度主要取决于零件的加工精度。其本质就是用控制零件的加工误差来保证产品的装配精度。按互换水平的不同,互换装配法又分为脱硫石膏烘干机中两种完整互换法和不完整互换法两种。
  Different methods can be adopted according to the performance requirements, structural characteristics, consumption mode and consumption conditions of desulfurized gypsum dryer products. Now it is described as follows: Exchange means that parts have interchangeability, which is a method that can reach the assembly accuracy request after installation without any selection and adjustment of the relevant parts in the assembly process of desulfurization gypsum dryer. When the product adopts the interchangeable assembly method, the assembly accuracy mainly depends on the processing accuracy of the parts. Its essence is to ensure the assembly accuracy of products by controlling the processing error of parts. According to the interchange level, the interchange assembly method can be divided into two complete interchange methods and incomplete interchange methods in desulfurization gypsum dryer.
