Recently, the field of ecological environment of Shanxi thorough investigation of illegal activities, promotion of eco-environmental quality of Shanxi be greatly improved, the central group held a provincial environmental inspectors rectification illegal sewage major renovation "Hundred Days cleared" special action mobilization meeting, asked the province up and down quickly action to ensure that the "Hundred Days cleared" special action to achieve tangible results.
"Clear Days" special action include 10 aspects: the central environmental protection inspectors and inspectors "looking back" clear feedback issues; national air pollution control and strengthen supervision and three cities in northern Shanxi air pollution control special inspection found problems rectification task clear; focus on the problem of sewage from polluting units cleared; "ban on coal zone" bulk coal cleared; "scattered dirt" enterprise is cleared; key areas of coal-fired boilers cleared out of the task; urban area construction site dust pollution problem is cleared ; diesel truck phenomenon of black smoke cleared; cities above the county level and type of surface water environmental violations centralized drinking water source protection areas cleared; annual key water pollution control project is completed cleared.
Clear focus: focus on examination of 624 key polluting units of pollution control facilities, operation and pollutant emissions. Implementation of the rectification May inform the Provincial Department of environment and supervise the handling of seriously overweight key sewage units - one by one to verify the fourth quarter of 2018, in 2019 the Department of Ecology and Environment informed the first quarter supervise the handling of seriously overweight key polluting units, 2019 1 situation and the implementation of administrative penalties.
Specific objectives: In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products, slashing the average concentration of sulfur dioxide in the ambient air quality.
Clear focus: the use of coal for municipalities within the scope of "no coal zone" in the home spot checks to ensure that alternative livelihood and heating coal for clean energy or clean heating methods is strictly prohibited within the store "ban on coal zone" sales and burning the behavior of coal and its products.
Clear Focus: targeted surveillance cities out of the task list of coal-fired boilers. In built-up areas to ensure that municipalities and districts out of 35 tons and coal-fired boilers, county (city) eliminated the basis of built-up area and 10 tons of coal-fired boilers on October 1, 2019, Taiyuan, Yangquan, Linfen City, Jinzhong city, four global, Luliang Fenyang, Xiaoyi, the text of water, Jiaocheng, Yuncheng salt lake, Wenxi, Xinjiang, Jishan, Hejin global phase-out of 35 tons of steam coal-fired boilers, Changzhi city completed 35 tons of steam out of the task more than 50% of the amount of coal-fired boilers, Jincheng complete 20 tons of steam coal-fired boilers eliminated within the municipal area.
Boiler Water Level Indicator fault how to do (1) such as boiler drum level table has a damaged: damaged door closed water table level immediately, valve open its doors hydrophobic. With another drum water level meter to monitor the normal water level in the drum. Take urgent measures to repair or replace damaged water gauge. (2) Drum Level two tables are damaged, but the boiler feed water automatically, water gauge differential pressure within one hour and the front drum level table has proofreading, confirmed that the correct and reliable, with reference to the feed water and steam flow meter instructions, continue to run for 20 minutes. In both cases, the squad leader should report the value of long, to maintain the stability of the boiler load, and to take urgent measures to replace the drum level table. (3) If the two tables are damaged drum water level, water level gauge while the differential pressure is unreliable operation, should the emergency shutdown process.
Do you know how to determine what level of small steam boiler? Severe steam with a large amount of water, increasing the salinity of small gas steam boiler, water hammer occurs in the sound of the steam pipe, steam connecting flanges outwardly take drip; feedwater flow is less than the steam flow rate, should the tube due to tube cracking or economizer when caused by lack of water, the opposite phenomenon occurs; when a serious water shortage, the door can be seen from the red-hot water wall tubes, but also smell the burnt smell, while tube may rupture, then you can hear the explosions, steam and smoke from the door, watching the fire door ejection.
The reason food factory boiler induced draft fan vibration generated by the induced draft fan vibration analysis of causes of food plant boiler induced draft fan of the analysis is to rely on the input of mechanical energy, increase the gas pressure side by side with mechanical feed gas has important applications in food plant boiler. But abnormal vibration induced draft fan will occur in the daily operation, not only will affect the equipment, but also affect the operation of the whole food plant boiler. Therefore, it is necessary to analyze the abnormal vibration induced draft fan. And to take appropriate and effective measures to do a good job to provide protection for the normal operation of the boiler plant food. Cause induced draft fan vibration analysis food plant boiler 1, via two rolling bearings fulcrum of the rotating rotor of the motor. Axial and radial clearance of the bearing is small, the smallest vibrations caused during cleaning and lubrication hole. Usually does not cause too much impact on the induced draft fan.
