GB/T 16911-2008Code of dust control for cement producting (English PDF)

Foreword

This standard replaces GB/T 16911-1997 "Cement Production Code of dust." This standard compared with GB/T 16911-1997, the main changes are as follows:

--- Increased (3rd edition chapter) chapter "Terms and Definitions";

--- Cement Plant Health Protection cited GB 18068 "Health protection zone standard cement" Cancel GB/T 3840-1991 "prepared Technical methods given local atmospheric pollutant emission standards, "the reference (1997 version 3.1, this version 4.1);

--- Increased mining dust requirements (Excerpts 5.5,7.1);

--- Refers to the standard "JT36" to "GB Z2" and "GB Z1" (1997 edition of 5.3.3.1,

7.3 Excerpts 6.3.3.1,

--- Added "factory sector fugitive emissions of particulate matter shall meet the requirements of GB 4915, there are areas where emission standards particulate emissions And plant community fugitive emissions of particulate matter emission standards should comply with local requirements "(this version 6.4.1);

--- Limestone, gypsum, clinker, coal, wood and other materials when mixed broken, "the general use of a bag filter or electrostatic precipitator" Edit To "should be used baghouse dust" (1997 version 6.1.1, this version 7.2.1);

--- The raw mill, cement mill dust "can choose one or two canceled dust and electrostatic precipitator according to their specific circumstances. A dust Use ESP or baghouse; two in the first stage of dust using a cyclone, the second stage uses electrostatic precipitator or a bag Dust, "was changed to" bag filter should be used "(1997 version 6.2.1, this version 7.3.1);

--- The "dry cement production, raw material grinding mill drying should be used to simplify the process and reduce dust production points" was changed to "should adopt the raw material grinding Dry grinding, simplify processes, reduce dust production points "(1997 version 6.2.2, this version 7.3.2);

--- When the "rotary dryer dust, dust can select a primary or secondary according to their specific circumstances. A dust, can use ESP Or baghouse. When two dust, the first stage may be a cyclone, the second stage uses baghouse or electrostatic precipitator Device "was changed to" dryer dust, the choice of bag filters or electrostatic precipitators "(1997 edition based on emission standards 6.3.1, this version 7.4.1);

--- The rotary kiln dedusting system "should adopt ESP or bag filter dust and other equipment" to "should be large Baghouse, and take measures to ensure that abnormal condition can still operate normally in the kiln and eliminate emissions of particulate matter under unusual circumstances. " (1997 version 6.4.2.1, this edition 7.5.2.1);

--- The kiln flue gas "according to the specific circumstances of the enterprise, the use of bag filter, electrostatic precipitator dust and other measures" to "should be used in addition to the bag After processing dust emissions "(1997 version 6.4.3.1, this edition 7.5.3.1);

--- Delete "Lepol ball into the kiln dust cover plate should be located exhaust dust" (1997 version 6.4.2.4);

1 Scope

GB/T 16911-2008 is the Chinese national standard on code of dust control for cement producting, in the field of environment and health protection, safety. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2009. Classification: ICS 13.100, CCS C70. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the cement producers in the site selection and plant design dust requirements, process design requirements for dust, dust workshop measures Shi, dust production process dust control measures, personal protection and dust management. This standard applies to cement manufacturers dustproof design, technological innovation and production and operation management.
