Qingdao Chemical Production Line Polyurethane Production Equipment

Description :

　　Chemical Engineering Principles Experimental Device - Gas Absorption Fluid Resistance Combination Experimental Device

　　Purpose of the experiment:

　　1. Observe the fluid dynamics behavior of the packed absorption tower and determine the relationship between the pressure drop of the packing layer and the gas velocity in the empty tower under dry and wet packing conditions.

　　2. Determine the total mass transfer coefficient Kya and understand its influencing factors.

　　3. Determination of straight pipe resistance and resistance coefficient.

　　4. Measurement of local resistance and resistance coefficient.

　　Compared with developed countries, there are indeed many urgent problems to be solved in the domestic chemical industry.

　　1. The large number and small scale of enterprises, with a dispersed layout, cannot have a significant impact on the international market;

　　2. The low product quality, coupled with insufficient scientific research and innovation capabilities, results in low technological content and added value of the product, making it difficult to form a competitive flagship product;

　　3. The production line has low flexibility and insufficient personalized production capacity, making it unable to adapt to the rapidly changing and increasingly diverse market demands;

　　4. The high cost is a common problem faced by any industry and enterprise, but it is particularly prominent in the domestic chemical industry.

　　Compared with developed countries, there are indeed many urgent problems to be solved in the domestic chemical industry.

　　The chemical industry can be said to make people both love and hate. Love "is because in life, from clothing, food, housing, transportation to various expenses, it covers all walks of life and can be said to be all encompassing; Hate "refers to the industry's" danger "," environmental protection "and other issues.
