This standard specifies the structural type and basic parameters, technical requirements, test methods, packaging, transportation and storage of tubular electric demisters. This standard applies to the following ranges: a) The processing gas volume is not greater than 5×10^(4)m^(3)/h (standard state); b) The working temperature is not greater than 45°C; C) The working pressure is -73×10^ (2) ~opa; d) Tubular electric mist eliminator for sulfuric acid production with an ambient temperature of -30~40°C and a relative humidity of 100%. This international standard is not applicable to the treatment of flammable and explosive smoke (special treatment should be carried out for flammable and explosive smoke). When the designed working conditions exceed the applicable scope of this standard. Its quality indicators should be specified in the product's technical documents (such as technical agreement).
