Abstract
This paper presents the results of diagnostics, describes the problems identified in the operation of exhaust ventilation systems in the storage rooms for storing reagents in the chemical workshop at the CHPP, and develops measures to improve their efficiency.
The results of the diagnostic survey showed the need for reconstruction and replacement of ventilation equipment and ducts with significant physical and moral wear and tear, which significantly worsened the technical and economic performance of the enterprise. In the warehouse premises, outdated ventilation equipment and ducts made of "black" metal were dismantled, and ducts and roof fans made of modern materials that do not corrode were installed.
These measures will allow:
- to increase the reliability of operation, energy efficiency, and environmental friendliness of exhaust ventilation; - to optimize the operation of ducts;
- to optimize the operation of the air ducts; - to save energy resources of the enterprise due to reducing the cost of electricity for moving air masses;
- to minimize the amount of emissions of sulfuric acid, ammonia and alkali vapors contained in chemically contaminated air of storage rooms.
Subject of research: exhaust ventilation systems of warehouses reagents of the chemical workshop of the CHP.
Methods and materials: The work used a practical method of analysis of the existing state of equipment.
Results: Analysis of the technical condition and diagnostics of the operation of the exhaust ventilation in the premises of the warehouses of reagents on the site of the chemical workshop, which is in operation of the CHP, confirmed the need to replace the ducts of "black" metal and outdated ventilation equipment with modern ones with high efficiency of operation. The dismantling of ducts and equipment with a large physical wear was carried out, corrosion-resistant ducts made of polypropylene were mounted, modern roof-mounted fans in a corrosion-resistant design were installed, and an emergency exhaust ventilation system was mounted, designed for 10-fold air exchange per hour. The repair and construction work was carried out in hazardous working conditions without stopping the technological process.
Conclusions: As a result of the modernization, the operation of the air ducts and fans was optimized. The implemented measures improved the reliability and technical and economic performance of the thermal power plant and minimized the amount of harmful emissions into the atmosphere.
