In order to advance the environmental protection standard management work, improve the production and surrounding environment, and create a green cleaning factory, after full investigation and preparation, the four quarter of 2019, the company began to implement the boiler color flue plume transformation project.
Since the commissioning of the company in 2011, the company has continuously deepened the investment and transformation of the boiler flue gas environmental protection emissions, ammonia desulfurization treatment, flue gas denitrification transformation, and environmental protection of ultra-low emission of flue gas. At present, the SEMS emission of our company's flue gas has reached the standard. In the face of increasingly stringent environmental protection policies, further implementation of the transformation of non-ferrous plumes, elimination of visual pollution through the removal of white smoke, and ensuring the normal operation of production and operation are imperative.
In order to reduce investment risk, the company has carried out research and technical exchange and field test demonstration of ammonia removal desulfurization process with the Xi'an coal and gas company in 电竞竞猜 mine. According to the experimental results and referring to some cases of power plant defrosting, the condensate + separation + reheat process is adopted, that is, a flue gas cooler is arranged in front of each boiler induced draft fan, and a set of flue gas condensing separation device, a demister device and a flue gas reheater device are set for each outlet of the desulphurization device. Through this process, the pollution factors in the flue gas can be effectively separated and recovered, so as to fundamentally solve the visual pollution of the existing flue gas.
Since 2020, affected by the new crown epidemic prevention and control, the project personnel, equipment, materials and other projects can not be put in place according to the plan.
The Ministry of science and technology development coordinated and coordinated, while approved the amount of work, reverse the construction period, the nodes were implemented to the week, the task was implemented to the people; on the one hand, they actively contacted the organization of the field construction personnel nucleic acid detection, coordinated personnel isolation observation and accommodation matters, and created conditions for the resumption of work. In March 1st, the plume management project resumed completely.
Since the resumption of work, construction works have been progressing rapidly. Up to now, 80% of 1# boilers and desulphurization towers have been prefabricated, and the total amount of flue gas anticorrosion is 60%. The amount of reinforcement for 1# flue gas outlet supports is 80%, and the reinforcement of 1# flue cooling flue supports is 90%. The whole project is expected to be completed by the end of June 2020.
The company's first color flue gas modification project is the first flue gas purification device combined with ammonia desulfurization and condensation separation and reheat technology. After commissioning, it will play a leading role in the industry. At the same time, after the completion of the project, the environmental protection emission index of the boiler flue gas will be upgraded to a higher level, which will effectively improve the surrounding environment of enterprises and demonstrate the corporate social responsibility.
