Why can others modify their own questions?

This is to optimize the quality of the problem, for the individual we want to get the answer, but for the platform it is to show everyone to see, when this problem is more and more people pay attention to, it means that this is a thing that can resonate with everyone, and everyone can participate in the problem to become clear and targeted.

No, you pay for the question above, this question is impossible for others to modify, no matter who can modify your question, they can only modify their own answers, not your question.

In fact, Zhihu's question is to make him achieve a more accurate and detailed purpose through everyone's adjustment to each other.

Is the landlord's password known to others, and then he changed your question, the landlord must pay attention, there are too many bad people now.

The electrostatic precipitator of the second burning machine head was transformed in 2009. The original factory site is limited, only the location of the new dust collector on the east side of the original dust collector, and the other 1 needs to be newly built at the original dust removal location. Since the electrostatic precipitator of the sintering machine head is the best production equipment, in order to reduce the impact on the production time.

Construction plan: build a new dust collector in the open space on the east side, and connect the east flue to this dust collector for the first time after the dust collector is completed. Dismantle the original Dongtai dust collector and build another dust collector, after the dust collector is completed, the second contact will be connected to the west flue to the new dust collector, the second burner head electrostatic precipitator was completed at the end of 2009, and the design emission concentration of the dust collector is 50mg m3.

The electrostatic precipitator of the second and third burning heads can meet the new national standards under normal production conditions. However, the emissions of western burning and new burning cannot meet the requirements of the new national standards. Domestic and foreign sintering head flue gas purification all use electrostatic precipitator, the new national standard requires the emission to be less than 50mg m3, which is difficult to achieve at present, although the electrostatic precipitator increases to 4 electric fields, but the sintering head electrostatic precipitator is affected by the process temperature, humidity, specific resistance is fluctuating, and the emission of sintering head electrostatic precipitator is also fluctuating, especially the fluctuation of sintering production, sintering machine start-up and shutdown, etc.

At present, more than half of the sintering machines in the country have completed flue gas desulfurization, that is, the dust in the flue gas has been further processed by the desulfurization process after passing through the electrostatic precipitator, and the exhaust flue gas can fully meet the new national emission standards. According to the requirements of the national "Eleventh Five-Year Plan" emission reduction plan, the ironmaking plant began to adopt the Danish rotary spray semi-dry desulfurization process in 2009, and successively completed the flue gas desulfurization facilities of 6 sintering machines, and the dust emission of 6 sintering heads of the ironmaking plant after desulfurization bag dust emission of 30mg m3 fully meets the requirements of the new national standard. In order to meet the requirements of the new national standard of 30mg m3, the existing electrostatic precipitator can be increased and transformed

The first is to increase the circulation area, reduce the wind speed of the electric field, and prolong the residence time of the flue gas medium in the dust collector, which is equivalent to dismantling the existing dust collector and widening and heightening it on the original basis; The second is to increase the number of electric fields, the original dust removal is retained, and the original inlet or outlet bell mouth is removed and increased to an electric field, so as to increase the area of the dust collection plate of the electric field, prolong the time for the flue gas to stay in the electric field, so as to improve the dust removal efficiency; Another solution is the electric bag reform scheme: retain the original electrostatic precipitator foundation, shell, ash hopper, bell mouth and ash conveying system, only remove the plate line and rapping system of the original electric field, and remake the upper box to install the cloth bag, but due to the increased resistance of bag dust removal, the original motor needs to be increased. The above scheme is comprehensively considered from the stability, effect, investment, construction period, site, etc., and the electric bag modification scheme is the best.

The production process of electricity is extremely complex, with multiple processes such as power generation, transmission, distribution, and consumption. Among them, power generation refers to the place where electric energy is produced, such as: thermal power units, hydropower units, etc.; Transmission refers to the operation of using high-voltage lines to complete power transmission; Substation refers to the use of high-voltage substation to convert high-voltage voltage, ultra-high-voltage voltage and other electrical energy into low-voltage electrical energy; Distribution is the final step, which reduces the voltage and delivers the electricity to the consumer.

The power transmission and transformation project of the power system attaches importance to the two steps of transmission and transformation. With the rapid increase in China's electricity demand, there is an urgent need for power system transmission and transformation projects to undertake the transmission and transmission of the power system. A number of power transmission and transformation projects together constitute the main frame of China's power grid.

At this stage, China's power transmission and transformation projects generally have multiple voltage levels such as 110kv, 220kv, 330kv, 500kv, etc., of which 220kv is used more frequently in China; 330kV is commonly found in China's northwest power grid; The 500kV level is the highest, and the requirements for cost, capacity, and process are higher and more advanced. At present, China attaches great importance to the construction of 500kV power grid, which is the backbone of China's power grid. Power transmission and transformation engineering is an important engineering project in the construction of the main grid of the power grid, including transmission line engineering and substation engineering, which requires high costs, extremely complex engineering construction, and high construction technical requirements.

Power transmission and transformation projects generally include electrical installation, communication and automation, civil engineering, electrical equipment commissioning, system start-up and commissioning, etc. Among them, electrical installation includes the installation of primary equipment such as high-voltage equipment, and also includes the wiring and installation of secondary equipment such as protection and control systems; Communication and automation refers to communication engineering and substation automation; Civil engineering covers equipment foundation, building engineering, four-way and one-level, frame foundation, etc.; The commissioning of electrical equipment is to test and adjust the installed primary equipment and secondary equipment; System start-up and commissioning refers to the start-up and commissioning of the operation of transmission lines and substations after the construction of power transmission and transformation projects. The status quo of power system power transmission and transformation project management does not pay attention to the coordination of the project scheduleThe power system power transmission and transformation project is very different from other projects, and the requirements of the power system power transmission and transformation project are higher, and the construction progress is required to be carried out in strict accordance with the specified requirements to ensure that the project construction is completed on time.

At this stage, most of China's power enterprises do not pay attention to the management and coordination of the progress of power transmission and transformation projects, which seriously affects the quality of the project, which not only reduces the ability of construction personnel and engineers to control the progress of the project, but also has a great impact on the efficiency and quality of the project. A small number of power transmission and transformation projects only pay attention to the progress of the project, and lack the supervision of the project quality, resulting in the problem of urban power shortage.
