Product Description

INTERMET

Ultra-Low Emission Environmental Protection Energy Island Process Package for Coal-Fired Flue Gas

01 Integrated Dust-and-Nitrate Process Route

Recommended Solution · One-Step Completion · Long-Term Benchmark

 

 

Project Overview

This solution employs an integrated process that deeply couples an advanced “YT baghouse dust collector” with an “SCR denitrification system.” It breaks away from the conventional segmented treatment approach and is specifically designed for new generating units or retrofit projects where ample site space is available. By enabling synergistic control under high-temperature, high-dust conditions, it addresses particulate matter and nitrogen oxide emissions in a single step, making it the ideal choice for achieving long-term ultra-low emissions.

 

Solution Advantages

  • Near-zero emissions, exceeding national standards: Particulate matter emissions are consistently maintained at ≤5 mg/m³, SO₂ at ≤35 mg/m³, and NOx at ≤50 mg/m³, with dust removal efficiency as high as 99.97%, easily meeting stringent environmental compliance requirements.
  • Long-lasting stability and extended service life: The core equipment is designed for a service life of up to 20 years, while the catalyst has a mechanical lifespan of up to 10 years. This fundamentally addresses the longstanding challenges of short lifespans and frequent maintenance in environmental protection facilities, resulting in lower total lifecycle costs.
  • High-temperature resistance and strong adaptability: The equipment is designed for operating temperatures as high as 400°C, with filter bags capable of withstanding temperatures up to 450°C, enabling it to reliably handle the complex flue-gas conditions typical of coal-fired boilers and ensuring continuous, stable system operation even under extreme conditions.

 

Technological Innovation Points

  • Core Technology Applications of YT Film: The use of YT membrane filter bags under the “Chengdu Yitai” brand breaks through the temperature resistance limits of conventional filter media, enabling dust-collection systems to operate directly and efficiently in high-temperature flue-gas environments ranging from 350°C to 400°C—without the need for complex cooling pre-treatment—and thereby significantly enhancing system thermal efficiency.
  • Deep collaborative integration of dust and explosives: An innovative integrated design that combines dust removal and denitrification reactors has optimized the flue gas flow field, significantly reducing the equipment footprint. Moreover, the dust removal process provides a clean flue gas environment for the SCR catalyst, effectively preventing catalyst fouling and poisoning.

02 SCR + Electrostatic Precipitation Baghouse Process Route

Flexible Solutions · Used-Equipment Retrofit · Cost-Effective Choice
 

 

Project Overview

For retrofit projects targeting aging units with constrained site space, tight construction schedules, or limited budgets, we have introduced the “SCR + Electrostatic Precipitation to Baghouse” solution. This solution leverages metal-membrane filter technology to upgrade existing electrostatic precipitators into high-efficiency baghouse dust collectors, while integrating an SCR denitrification system. By adopting a phased implementation approach, the solution provides flexible solutions to both particulate matter and nitrogen oxide emissions, making it particularly well-suited for retrofitting existing power plants in densely populated urban areas where land is at a premium.

 

Solution Advantages

  • Extremely compact footprint and easy to implement: By fully leveraging the existing electrostatic precipitator housing for retrofitting, there is no need to acquire substantial additional land, thereby perfectly addressing the challenge of space constraints.
  • Phased implementation to alleviate pressure: Phased construction is supported: Phase I will first address particulate matter emissions and reserve an SCR interface, while Phase II will then complete the denitrification system. This approach effectively alleviates short-term funding pressures on enterprises and reduces the risk associated with one-time capital investment.
  • Precise compliance and high cost-effectiveness: The outlet particulate concentration can be reduced to below 10 mg/m³, fully meeting environmental protection requirements, while the project duration is short and the temporary disruption to existing production is minimal.

 

Technological Innovation Points

  • Metal Membrane Filter Technology: The introduction of high-performance metal-membrane filter elements not only delivers outstanding filtration accuracy but also exhibits exceptional corrosion and wear resistance, making them ideally suited for retrofitting older dust collectors.
  • Optimized Design for Reusing Existing Structures: The innovative structural design enables the new baghouse dust-collection system to be seamlessly integrated into the existing electrostatic precipitator housing, effectively “putting new wine in old bottles,” thereby maximizing the utilization of existing assets and minimizing steel-structure waste.
  • Modular SCR Integration: In response to the irregular spatial layout of retrofit projects, a modular SCR reactor design is employed to provide flexible adaptation to the on-site space configuration while ensuring that denitrification efficiency remains uncompromised.
