[Chemical Knowledge]:Using "Chimney Principle" to Realize Efficient Exhaust

In the process of production, processing and use, many industries need to emit waste gas, such as industrial production, catering and other fields. If not timely exhaust, these emissions will affect human health, but also increase environmental pollution.

It is well known that the exhaust system is one of the regular ways to solve exhaust emissions. In the exhaust system, the use of "chimney principle" can achieve efficient exhaust.

chimney principle refers to the chimney inside, because the air flow is affected by temperature, the air in the different temperature between the pressure, so as to form an upward air flow, driving exhaust emissions. Using this principle, efficient exhaust can be achieved.

in the exhaust system, should be as far as possible to avoid blocking the air flow, increase the diameter of the chimney, extend the height of the chimney, increase the number of chimney sections, etc., in order to increase the airflow speed. Attention should also be paid to the location and size of the chimney mouth to make full use of the difference in airflow to drive exhaust.

In practical applications, we can choose different fans, chimney diameters and heights according to the different types and concentrations of pollutants discharged to ensure that exhaust gas can be discharged smoothly, while achieving environmental protection and energy saving.

In general, the use of chimney principle to achieve efficient exhaust is a scientific and environmentally friendly method. In daily work and life, we should pay attention to the construction and maintenance of the exhaust system to ensure the working environment and healthy life.
