What are the characteristics of a deodorization tower
Information summary:The deodorization tower has the following characteristics:
1. Edible oil refining and deodorization tower
Efficient deodorization: It can effectively remove small molecule odorous organic compounds such as free fatty acids, aldehydes, ketones, etc. from oils and fats under high temperature and high vacuum conditions, significantly improving the quality and flavor of oils and fats
The deodorization tower has the following characteristics:
1. Edible oil refining and deodorization tower
Efficient deodorization: It can effectively remove small molecule odorous organic compounds such as free fatty acids, aldehydes, ketones, etc. from oils and fats under high temperature and high vacuum conditions, significantly improving the quality and flavor of oils and fats
Multiple types: Common types include plate type deodorization tower, packed type deodorization tower, and combination type deodorization tower. The plate deodorization tower has good thermal decolorization effect, but it consumes a large amount of steam; The packed deodorization tower requires less steam for stripping and has a better deacidification effect; The combined deodorization tower combines the advantages of both and is widely used
Correct control: There are strict requirements for parameters such as temperature, pressure, steam flow rate, and time during the operation process to ensure good deodorization effect. The general temperature is between 230-270 degrees Celsius, and the operating pressure is around 0.27-0.40 kPa
Reasonable structural design: For example, the liquid level adjustable drum type deodorization tower optimizes the internal structure, allowing the liquid level of each layer in the plate tower section to be adjusted, which can be suitable for different varieties and qualities of oils and fats, and solves the problems of uneven deodorization stripping and long deodorization time in the oil refining process
2. Garbage room exhaust gas treatment deodorization tower
High deodorization efficiency: It can efficiently remove odorous gases such as hydrogen sulfide and ammonia generated in the garbage room, improve air quality, avoid odor rebound, and significantly enhance the environmental quality of the garbage room and its surrounding areas
Low energy consumption: With low operating energy consumption, it meets the requirements of energy conservation and environmental protection. For example, the biological deodorization tower uses the natural metabolic process of microorganisms for deodorization, without consuming a large amount of energy
Low noise: The noise generated during operation is low and will not cause interference to the surrounding environment
Environmentally friendly: It does not generate secondary pollution and is conducive to protecting the ecological environment. For example, biological deodorization towers use microorganisms to decompose odorous organic matter in odors into harmless substances such as carbon dioxide and water
3. Chemical washing deodorization tower
Strong targeting: It has good removal effects on specific pollutants. For example, alkaline washing towers are suitable for removing odorous substances such as hydrogen sulfide and lower fatty acids, acid washing towers can remove alkaline odorous substances such as ammonia and amines, and multi-stage chemical washing methods can remove various types of odorous substances present in exhaust gas
Simple structure: easy to construct, with fewer structures to handle, less equipment requirements, simple operation and management, and relatively low maintenance costs.
