Exhaust gas purification towers
need to pay attention to details during use. For cities, more and more cars are now emitting more and more exhaust gas, which has a great impact on the environment. Of course, they also include exhaust gases emitted by some industrial enterprises during their production and manufacturing processes, which also pollute the environment. As far as the current purification equipment is concerned, the exhaust gas purification tower is a relatively new type of purification equipment and has played a very good role. During use.
Since the exhaust gas purification tower is a high-tech equipment, the effect is also very obvious in the process of use. Therefore, the price in the market is relatively high. Although the price is higher, it can be used for a long time. On the other hand, the use time of the purification equipment can be guaranteed.
In general, the following details should be paid attention to when using this kind of equipment, because the use of this equipment requires a combination of liquid substances and gases, so there should be enough space in the installation. As long as the process is used, paying attention to these two aspects can basically extend the life of the equipment.
Of course, the exhaust gas purification tower also has many advantages in the process of use, and its energy consumption during use is very small, which can be said to be energy-saving. In addition, the entire structure is relatively simple and easy to perform routine maintenance.
Next, the team analyzes what to do if the exhaust gas purification tower of the exhaust gas treatment equipment is blocked.
First of all, the desulfurization operator of the exhaust gas purification tower of the exhaust gas treatment equipment should strengthen the sense of responsibility, carefully observe the changes in the resistance of the desulfurization system, and report the abnormal situation to the workshop and relevant departments in time. Regularly perform electrostatic dedusting and establish statistical reports on sulfur production. Count the amount of sulfur produced in shifts, promote sulfur recovery, balance sulfur, and reduce suspended sulfur in solution.
Secondly, the process and operation management should be strengthened. The regeneration tank should be continuously (or intermittently) sprayed from the sulfur foam into the foam tank. The recovery liquid should be settled before the system is used. Through the process calculation, a suitable solution cycle should be selected. d. Periodically increase the solution circulation, intermittently flush the exhaust gas purification tower packing section, strengthen the cooling tower water quality and semi-water gas pretreatment, increase the amount of water on the scrubber before desulfurization, open electrostatic decoking, and reduce the coal dust content. The tar is used to replace the desulfurization system, and the components of the desulfurization solution are strictly controlled, and the pH value, total alkalinity, Na2CO3, NaHCO 3, side salts and suspended sulfur are controlled within the target range.
For lye tannin extraction desulfurization solution, the main components of total vanadium and tannin extract were adjusted. The ratio of total vanadium to tannin extract was 1.5: 1. In production, this index should be strictly implemented and checked to ensure the regeneration air volume and blowing intensity, ensure the regeneration effect, and fully analyze and separate elemental sulfur.
The study found that the resistance of the exhaust gas purification tower of the exhaust gas treatment equipment increased. According to the specific situation, analyze and determine whether it is sulfur block, alkali block, salt block or mechanical impurity block, and take corresponding measures. The y-type desulfurization catalyst 888 with washing effect can be used instead. If the packing plug of the tower is mechanical impurities or total salt, adding 888 cannot reduce the resistance of the tower, but if the mixture of sulfur and salt, when sulfur is washed down, the salt will Gradually decompose and release.
填料段松动物料自上而下移动，有时形成局部阻力增大，几天内即可恢复正常，当废气处理设备废气净化塔压差不能满足安全生产要求时，必须停工再补给。 The pine material in the filler section of the exhaust gas purification tower moves from top to bottom, sometimes forming local resistance increases, and can return to normal within a few days. When the pressure difference of the exhaust gas purification tower of the exhaust gas treatment equipment cannot meet the requirements of safety production, it must be stopped and resupplyed. When the resistance of the exhaust gas purification tower of the exhaust gas treatment device increases, in order to maintain production, citric acid can be added to the desulfurization liquid to slow down the tendency of the resistance to increase. The amount of citric acid added was 10 Kg, 100 M3 / time.
