Embodiment 1

[0034] see figure 1 In this embodiment, the method for the whole process management of the denitrification catalyst life is described in detail by taking the A power plant project as an example, and the specific steps of the method are as follows.

[0035] The denitrification transformation project of power plant A determines that the denitrification process is SCR denitrification process, which requires the use of catalysts. For the smooth implementation of the project, while determining the transformation process, a catalyst life-cycle management plan was formulated to ensure that the production, commissioning, and final disposal of catalysts can be properly handled to prevent problems before they happen, and to ensure that power plant A can use catalysts with superior performance , without generating solid waste. After formulating the whole process management plan of catalyst life, the implementation process of the whole process management plan of catalyst life is establis...

Embodiment 2

[0042] see figure 1 , the steps of the method for the whole process management of the life of the denitration catalyst in this embodiment are as follows.

[0043] (1) Formulate a management plan for the whole process of catalyst life.

[0044] (2) Determine the catalyst manufacturer, appoint professionals to supervise and inspect the catalyst production process and product quality, and form a supervision and inspection report.

[0045] (3) For qualified catalyst products leaving the factory, entrust a third-party testing party to conduct random sampling performance testing of the catalysts to be put into operation, and issue a test report.

[0046] (4) Before the qualified catalyst products are put into use, the arrival inspection is carried out, and the acceptance report is formed, and then installed and put into operation.

[0047] (5) For catalysts that have been put into operation for a certain period of time, entrust a third party to conduct performance acceptance tests...

Abstract

The invention relates to a denitration catalyst life whole-process management method. A denitration catalyst life management method beneficial to stable and efficient running of a denitration system does not exist at present. The method comprises the steps that 1, a catalyst life whole-process management scheme is made; 2, a catalyst manufacturer is determined, and the catalyst production process and product quality are supervised and examined; 3, random sampling performance detection is carried out on qualified catalysts planned to be put into operation; 4, inspection of incoming merchandise, installation and commissioning are carried out on the catalysts which are detected to be qualified before the catalysts are put into operation; 5, performance acceptance testing is carried out on the catalysts which are put into operation for a certain period of time; 6, after quality inspection before acceptance is qualified, catalyst performance detection is carried out at regular intervals, the catalyst commissioning effect is tracked, diagnosis optimization experimentation is carried out, and the catalyst service life is prolonged; 7, a deactivated catalyst is regenerated for use. The denitration catalyst life whole-process management method is beneficial to the sable and efficient running of the denitration system.

Description

technical field [0001] The invention relates to a method for managing the whole process of life of a denitrification catalyst, and belongs to the technical fields of air pollution control and solid waste recycling. Background technique [0002] In July 2011, the Ministry of Environmental Protection of the People's Republic of China issued the new "Emission Standards of Air Pollutants for Thermal Power Plants" (GB13223-2011), which further strictly restricted the emission limits of nitrogen oxides from thermal power plants. Thermal power units across the country are facing The urgency of denitrification transformation, selective catalytic reduction (Selective Catalytic Reduction, hereinafter referred to as: SCR) flue gas denitrification technology is the mainstream technology of denitrification transformation, and the core technology of SCR is the catalyst used in the process. [0003] At present, the service life of SCR catalysts used in industry is only 3 to 4 years, and th...
