First of all, the coarse and fine filter elements filter the lubricating oil, and the coarse filter element protects the fine filter element. The main impact of the filter element is the oil supply pressure to the turbine. I don't know what your turbine oil supply pressure requirements are, but as long as it can meet the turbine lube oil pressure you will be fine. If the filter is clogged, the pressure of the lubricating oil will drop. Simply adjust or clean the filter element.
Second, the main valve should be manually adjusted up and down, and the electrical isolation valve is also manually tested to prevent it from getting stuck due to long-term operation. However, it is usually necessary to do this under low load conditions to avoid shutdown caused by improper operation.
Third, the oil filter under viis actually very simple. These include coarse and fine filter elements, and some also have permanent magnet filter elements, vacuum pumps, heaters, oil pumps, floats, not to mention the small parts. The specific function is to filter the oil through the filter element to remove impurities or iron filings; use a vacuum pump to evacuate the vacuum chamber, and the oil will enter the vacuum chamber after being heated, and the water in the oil will be separated. under vacuum. The oil pump sends the oil out of the oil filter to be recycled. Moisture in the turbine oil is mainly caused by leakage of the shaft seal, entering the lubricating oil of the bearing and returning to the bottom of the oil tank. If the turbine continues to operate, it must be drained frequently. The drainage point should be at the lowest point at the bottom of the oil tank, in order to guaranteeensuring that the moisture content of the turbine oil does not exceed the standard. Generally, water leaks from the oil cooler will not enter the oil tank because the oil pressure is much higher than the pressure of the circulating water, which will only cause oil to enter the oil tank. the circulation pool. Therefore, as long as the oil pressure remains higher than the pressure of the circulating water, a large amount of water will not enter the oil.
How to increase the electricity generation capacity of waste thermal energy production of cement kilns
According to the production capacity and financial conditions of the vertical kiln plant, the first step is to use the waste thermal energy generation kiln (hollow kiln). Add secondary thermal power generation technology to replace the vertical furnace. For example, a vertical kiln factory has three ligproduction of 88,000 tonnes. It can stop the production of two vertical kilns and build a hollow kiln with a diameter of 3.6 meters x 74 meters and an additional 4,500 kilowatt steam waste thermal power generation system. The investment in this stage is around 3,600 to 38 million yuan. Secondly, use the fluidized decomposition furnace plus 1-stage or 2-stage suspension preheating technology, and then carry out the technical transformation of the waste thermal energy generation furnace, that is, for the furnace factory vertical mentioned in the example above, stop production of the third. vertical oven, and renovate the one already built. The hollow kiln with a diameter of 3.6 meters by 74 meters is equipped with a fluidized decomposition furnace and a preheater suspended on 1-2 stages at the same time, partial processing of waste. a heat boiler is made. The investment in thisstep requires about 8 to 10 million yuan. After the above two-stage transformation work is completed, the original vertical kiln plant will be transformed into a precalcination kiln plant with a total investment of 45-50 million yuan, and the total clinker production will be maintained at the combined level of the original. three vertical ovens. Provided that the factory price per ton of standard coal does not exceed 180 yuan, the production cost of cement can be reduced to less than 95 yuan.
Increase the flue gas temperature and air volume at the boiler air inlets at the head and tail of the furnace. Power output can be increased by increasing the vacuum level of the condenser, which can increase power output. At present, the factor that has the greatest impact on electricity generation is boiler evaporation, especially the instability of the conductite of cement in the kiln head boilers. This requires a lot of coordination in furnace operations. Timely adjustment can increase power generation. Other influencing factors are the vacuum degree, which must be checked to increase the vacuum degree to the required range. Don't take too long to start, increase the drain hose and reduce the preheating time. To extend the downtime, when the furnace is stopped, you can coordinate the operation of the furnace, stop the fan as slowly as possible, and continue to blow the wind, which can extend the power generation.
The cement rotary kiln belongs to the category of building materials equipment and is a type of lime kiln. It belongs to the category of building materials equipment and is a type of lime kiln. Rotary kilns can be divided into cement rotary kilns, chemical rotary kilnsmetallurgical technologies and rotary lime kilns according to the different materials processed. Cement rotary kiln is the main equipment of dry and wet cement clinker production lines.
