Foreword
This standard is for Revision of ZBJ88001.2-88 Electrostatic Precipitator Types and Basic Parameters and JB/T5910-.914 Electrostatic Precipitator Technical Conditions.
This standard will replace 2BJ88001.2-88 and JB/T5910-91 from the effective date. This standard was proposed and centralized by the Electrostatic Precipitator Sub-Technical Committee of the Environmental Protection Machinery Standardization Technical Committee of the Ministry of Machinery. The drafting unit of this standard: Jianjiang Feida Mechanical and Electrical Group Co., Ltd. The main drafter of this standard: Chen Jianguo.
This standard is entrusted to the Electrostatic Precipitator Sub-Technical Committee of the Environmental Protection Machinery Standardization Technical Committee of the Ministry of Machinery to be responsible for interpretation. 1 Scope

JB/ T 591091 | . This standard is applicable to the following ranges:
a) Flue gas treatment capacity %4.5×10°m/h (in standard state): b) Flue gas temperature ≤400C (>250C is high temperature type): c) Same-pole spacing 250~600mms
d) withstand allowable pressure -4.0×10*~0Pa (of which -1.0×10°~0Pa is the conventional type: -4.0×10*~1.010*Pa is the high-pressure type) :
e) The dust concentration of the inlet flue gas is ≤100g/m (under standard conditions). This standard does not apply 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, the quality indicators should be specified in the product's technical documents (such as technical agreement).
