  • Dec 14, 2022 "Detail Complex" in the catalyst workshop at Yuanchen
    A "screw" may seem ordinary, but it is an indispensable part of the normal operation of the whole chain. Liu Mishang is such a "screw", since he joined the company in July 2018, he has been transferred 5 times, whether it is cutting and assembling, or doing a dry room management in the catalyst workshop, he is a soldier, always meticulous, standing the first shift after the catalyst products are formed. Liu Misheng (first from left) was awarded the title of Outstanding Veteran The "housekeeper" of 80 drying rooms When you walk into the catalyst workshop of Yuanchen Technology, you will see two rows of sealed "facade rooms", marked with temperature, humidity, days and times. This is Liu Misheng's "best friend" - a dry room in the catalyst workshop. There are a total of 80 drying rooms, and Liu Mishang knows the situation of the drying rooms like the back of his hand. Every day at 8 o'clock, he has to put on the protective mask and start the inspection of these drying rooms, a circle down, at least 3 hours, "according to the weather conditions, timely observation to adjust the temperature and humidity inside the drying room, to ensure that each drying room normal operation." Speaking of this job, Liu Misheng has a deep memory. "At that time, because of the small space available for people to move into after a sufficient amount of catalyst was put into the drying room, coupled with the occasional smell of ammonia, almost no one wanted to do it." At first Liu Misheng was also a bit daunted, and after a week of studying with the team leader, he took the initiative to come on board and continue to learn while figuring it out. "Do a line of work and love a line of work, no matter what, do the work must have a sense of responsibility, to make people feel at ease, so that others say less, or even can not say gossip." Soon, Liu Misheng entered the role: in addition to the Spring Festival holiday and September to send children to learn to take a few days off, almost no rest every month ", every day into the workshop the first thing is to see the drying room, before leaving work is also to see the drying room again before rest assured out of the workshop. As the "full-time housekeeper" of 80 drying rooms, Liu Misheng is familiar with each drying room, each piece of equipment and each parameter, meticulously ponders over the working methods and takes the initiative to cooperate with the team to complete the transformation of the drying room, successfully achieving the production goal of both racing against time and safely increasing speed and efficiency. Nowadays, only special projects take 11-12 days after the transformation, other projects take 9-10 days in summer and only 10-11 days in winter, and the product qualification rate has also increased significantly compared to before. Liu Misheng recording information on drying room data Meticulous detail complex All along, Liu Misheng insists on paying attention to details in his work and does not do Mr. Almos...

  • Yuanchen Technology: How to make filter bags for thermal power plants more durable
    Dec 09, 2022 Yuanchen Technology: How to make filter bags for thermal power plants more durable
    For users of coal-fired boiler flue gas purification bag filter in thermal power plants, the most important concern is the service life of the dust bag. There are two main factors that affect the service life of the dust bag: one is the thermal and chemical nature of the flue gas, and the other is the mechanical loss of the filter bag during the filtration and ash cleaning process. 1, chemical fiber filter media must be fully considered the thermal and chemical effects of the flue gas. Such as the oxidation of PPS filter media, acid condensation and ultra-high temperature operation, it may lead to the filter bag soon breakage and failure. In view of this, even if the filter media itself is good in terms of functional filtration efficiency and ash removal performance, it is difficult to reflect its comprehensive effect and value, because "good effect but more wear and tear" is not our goal. In the harsh flue gas, especially the heat and chemical effects of strong dusty flue gas, all customers and filter media manufacturers must seek new filter media to resist high temperature and smoke corrosion. 2. The filtration performance of the filter media affects the actual service life of the filter bag. The filter media must operate normally under the conditions of the flue gas, the functional (performance) quality of the filter media mainly refers to the filtration efficiency and ash removal performance. Good filtration efficiency of the filter media means that the dust can be well blocked on the surface of the filter media and rarely penetrate into the middle of the filter media, which not only reduces the wear and tear of the dust particles on the filter fibres during the movement of the filter bag, but also enables the dust on the surface of the filter media to be removed in the largest quantity. Therefore, good performance off ash, filter media due to dust layer agglomeration and the formation of running resistance is small, a dust cleaning and then rise to set the dust cleaning pressure cycle will be extended. The longer the cleaning cycle, the number of times the filter bag needs to be cleaned is reduced, the less the number of times the filter bag is mechanically damaged, the longer the service life of the filter bag. 3, "fixed pressure dust cleaning" than "timing dust cleaning" is more appropriate. Many customers use the traditional timing of ash cleaning, but the timing of ash cleaning is not enough too mechanical, because when the filter bag operating pressure difference may not be high, to clear the ash has not reached the level to be cleared, the implementation of the filter bag cleaning, which increases the chance of mechanical damage to the filter bag and the number of times. If the use of "fixed pressure dust cleaning", sometimes although not to the traditional dust cleaning time, but may want to clear the dust has accumulated a lot, the operating pressure may be significantly more than the limit, and then not clear the resistance may furt...

  • Yuanchen Technology: Filter bag use and maintenance
    Dec 07, 2022 Yuanchen Technology: Filter bag use and maintenance
    The dust bag in use should prevent the gas from cooling below the dew point inside the bag chamber, especially if the bag dust collector is used under negative pressure. As air often leaks into the casing, the bag chamber gas temperature is lower than the dew point and the bag becomes damp, resulting in a dust dust bag in use to prevent the gas from cooling below the dew point in the bag chamber, especially when using a bag filter under negative pressure. As its shell often has air leakage, so that the bag chamber gas temperature is lower than the dew point, the filter bag will be damp, resulting in dust not loosely, but stickily attached to the filter bag, the fabric holes blocked, resulting in dust cleaning failure, so that the dust collector pressure drop is too large, can not continue to run, and some produce paste bag can not remove dust. To prevent condensation, the temperature of the gas in the dust collector and its system must be kept higher than its dew point by 25 to 35°C (e.g. the dew point temperature of the kiln mill is 58°C and the operating temperature should be above 90°C) to ensure the good use of the filter bag. Its measures are as follows. I Take appropriate heating measures. Such as far-infrared electric heater, electric heaters in the dust collector, or additional heaters in the bag chamber, which can appropriately improve the flue gas temperature of the host. Strengthen the temperature monitoring of the dust collector and dust removal system in order to grasp the conditions of use of the baghouse and prevent the generation of condensation. II Reduce air leakage. Leakage of air from some gaps in the dust collector body, leakage of air from the dust collector filter bag body should be controlled at less than 3.5%. The air leakage of process equipment in the dust collector system such as the airtight ash discharge valve at the discharge port of the ball mill, the air leakage of the airtight ash discharge valve under the dust collector, the pipe flange connection, etc., are often ignored by the maintenance management personnel, thus, increasing the amount of unnecessary air leakage and deteriorating the operating conditions of the bag filter. III Additional raw material stacking sheds. In cement production, various raw materials, fuels and mixed materials have different water content, if they are placed in a fixed pile shed to prevent rain, the water content of the materials can be greatly reduced, which is an effective measure to reduce the water content of the materials. This is an effective measure to reduce the water content of materials. In the cement factories in the south of China, this situation is relatively common, but some of the material pile sheds are too small, and some are not, therefore, causing some difficulties for the use of bag filter. IV Do a good job of insulation and rainproofing of dust collectors, pipes and other relevant parts. Practice has proved that good insulation measures can make the difference b...
