Recently, Haoyuan company has received many good news and good reports. The gasification workshop has been awarded the honorary title of "Anhui worker pioneer" by Anhui Provincial Federation of trade unions; Comrade Wang Weifeng has been awarded the advanced individual of Fuyang labor competition and Fuyang May 1st Labor Medal by Fuyang labor competition committee and Municipal Federation of trade unions; Comrade Zhang Yanqing has been awarded the honorary title of "Yingdong district labor model".

The gasification workshop is an outstanding team that is united and vigorous. The first stage gasifier has been running continuously for 321 days from 2016-2017 to 468 days in 2017-2018, which is the longest continuous operation record of all pulverized coal gasification units in the world, and has become a shining pearl in the industry. It has made great efforts to promote China's pulverized coal pressurized gasification technology to the world and to a new height He has made a positive contribution.

Wang Weifeng is now assistant to the general manager of Haoyuan company. Over the years, he has always adhered to the enterprising and tenacious spirit of daring to break through, dare to fight hard battles and constantly strive for self-improvement. He is good at bursting out wisdom under pressure and looking for solutions in difficulties. During the construction of the space furnace project of the company's headquarters, he was responsible for the first set of sulfur resistant wide temperature adiabatic shift device in China. The process technology overcame the disadvantages of large resistance and high consumption of other similar devices in China. In line with the scientific and rigorous working attitude, combined with years of rich work experience, he carefully designed and scientifically organized, which not only ensured the success of the first start-up of the space furnace, but also achieved the level of low consumption and high output among similar domestic devices. In the selection and construction of tail gas recovery device for aerospace furnace, he selected the wet process of sulfuric acid production from tail gas with domestic independent intellectual property rights after many times of investigation, which successfully broke the situation that the technology has been monopolized by foreign countries for decades at one fell swoop. It has made outstanding contributions to environmental protection production and saved a lot of funds for the company. In addition, the 260000 t styrene project in Haoyuan group Park, which he was responsible for, was successfully started in August 2018.

Mr. Zhang Yanqing is currently working in the mechanical repair section of the park maintenance center of Haoyuan company. After the introduction of pressure tapping technology into the company, he took the initiative to explore and study, and solved many problems in production. In the aspect of environmental treatment, in order to eliminate the odor of methanol wash air, a new adsorption tank was determined to carry out active carbon adsorption. Through the pressure opening technology, the shutdown and grid connection were avoided. In addition, he has solved the problem of tapping stainless steel pipes under pressure by means of small-scale transformation and using existing equipment. At present, the success rate of small-diameter stainless steel tapping under pressure is 100%. There is a high risk of pressurized opening in low-pressure steam system. The seal ring of the original equipment is easy to melt during preheating, which will lead to a large amount of steam leakage and cause personal injury. Zhang Yanqing successfully solved the problem of pressurized opening of low-pressure steam system by changing the sealing form, increasing external cooling and blocking measures. The pressure tapping technology of low-pressure steam system has been successfully applied in the utilization of high flash vent steam of gasification in the park. It can save 7-8 tons of steam of 0.5MPa per hour and save more than 5 million yuan for enterprises in the whole year.
    the company calls on all employees to take advanced figures and advanced teams as examples, never forget their original intention, forge ahead with determination, base on their posts, concentrate on research, and strive to arm themselves into high-quality workers in the new era, and make new contributions to the rapid development of Haoyuan company.
