I. Introduction.
In industrial production, the coking process produces a large amount of flue gas, which contains a large amount of tar. In order to effectively treat these flue gases and reduce environmental pollution, electric tar precipitators came into being. The electric tar precipitator mainly adsorbs the tar molecules in the flue gas through the polarity effect generated by the high-voltage electric field, so as to achieve the effective removal of tar. This article will focus on the change in suction power before and after the electric tar precipitator.
Second, the principle of electric tar precipitator.
The working principle of the electric tar precipitator is mainly to use a high-voltage electric field to separate the flue gas, and adsorb the tar in the flue gas through the polarity effect. Specifically, there are multiple electrodes inside the electric tar precipitator, and through the action of a high-voltage electric field, the water and gas molecules in the flue gas will be ionized to form charged ions. At the same time, the tar molecules in the flue gas are also adsorbed by the electric field, forming polar molecules that are adsorbed to the electrode.
3. Influencing factors of suction power change.
1.Electric field strength: The higher the electric field strength, the better the tar molecules in the flue gas are adsorbed. This is because the electric field strength increases, which can enhance the polarity effect and improve the adsorption efficiency.
2.Flue gas velocity: The flue gas velocity also has an effect on the suction variation. If the flow rate is too high, the electric field may be unstable and affect the adsorption effect. If the flow rate is too low, it may lead to incomplete adsorption and affect the treatment efficiency.
3.Equipment structure: The structure of the equipment such as electrode spacing, material, etc. will also affect the suction power change. The right electrode spacing and material can improve the stability of the electric field and enhance the suction.
Fourth, the experimental results and analysis.
In order to study the change of suction power before and after the electric tar precipitator, we conducted a series of experiments. The experimental results show that the suction power increases significantly after using the electric tar precipitator. This is because the tar content in the flue gas is high before use, and a large suction power is required for effective adsorption. After the use of the electric tar precipitator, the moisture and gas molecules in the flue gas are reduced due to the effective adsorption of the tar, resulting in a significant increase in suction power. At the same time, we found that with the increase of use time, the suction power changes less, indicating that the performance of the device is stable.
V. Conclusions and Recommendations.
In summary, the suction power of the electric tar precipitator increases significantly after use, and the performance is stable. In order to further improve the effect of the electric tar precipitator, we make the following recommendations:
1.Regularly check the structure of the equipment to ensure that the electrode spacing, material and other parameters are reasonably set.
2.Maintain the equipment regularly and keep it up and running.
3.Adjust the electric field strength and flue gas velocity according to the actual working conditions to improve the suction power and treatment efficiency.
Through the implementation of the above measures, we can better use the electric tar precipitator to treat the tar in the flue gas, reduce environmental pollution, and achieve the sustainable development of industrial production.
