Dry spray deodorization equipmentMainly utilizing the biological principles of plant fluids (currently, our company mainly uses dry methods, but also wet methods).
Introduction to Plant Liquid Waste Gas Treatment:
The investment in odor removal and exhaust gas purification is low, the operation is convenient, and it has a wide range of applicability, occupies less land, does not require changes, additional structures, and many additional facilities. The use of odor control system does not require a large amount of electricity, is simple to use, convenient for workers to operate, requires regular replenishment of working fluid, and has low maintenance and operating costs for the entire system. The exhaust gas purification system is not suitable for enclosed indoor spaces and is suitable for the treatment of industrial exhaust odors.
Biological treatment of plant fluids decomposes upon contact with odor molecules in the air, and the resulting products are substances such as water, oxygen, nitrogen, and so on. The characteristic of deodorizing liquid is that it decomposes odor molecules in the air, rather than masking odors.
Plant deodorizing solution decomposes odor molecules rather than masking them, which is a combination of deodorizing solution and chemical deodorizers. The deodorant is atomized by the high-pressure spray equipment to form a fog, and diffuses in the space or pipeline. The radius of the droplets is ≤ 5 μ m. Droplets have a large specific surface area and surface energy, with an average of several tens of kilocalories per mole. This amount of energy is already 1/3-1/4 of the bond energy in many elements. The surface of the solution adsorbs odor molecules from the air, and at the same time, it can change the three-dimensional configuration of the adsorbed odor molecules, weaken the chemical bonds in the odor molecules, increase the instability of the odor molecules, and easily interact with other molecules and the acidic buffer in the deodorizing solution. Under the action of deodorizing solution, hydrogen sulfide reacts to generate sulfate ions and water; Under the action of the deodorizing solution, ammonia generates nitrogen gas and water.
The molecules contained in the deodorizing solution mostly contain multiple conjugated double bond systems, which have a strong ability to provide electron pairs, thereby increasing the reactivity of odor molecules.
The odor molecules adsorbed on the surface of the deodorizing solution come into contact with oxygen in the air. At this time, the odor molecules become reactive due to the above two reasons, changing the mechanism of reaction with oxygen and allowing them to react with oxygen at room temperature.
The reaction between deodorizing solution and odor molecules is as follows:
A. Acid-base reaction
B. Catalytic oxidation reaction
C. Lewis acid-base reaction.
D. Discuss from a thermodynamic perspective.
E. Redox reaction
In theory, plant deodorizers can remove odors from exhaust gases by utilizing the following forces: 1. van der Waals forces; 2. Combined force; 3. Chemical reactivity; 4 Attractiveness
There are the following stages for deodorizing liquid to remove odors: deodorizing liquid relies on van der Waals force to bind with odor molecules.
In addition, the deodorizing solution can also contain chlorine gas and carbon dioxide, which are removed by generating a corona around the particles. After the corona is generated, the gas molecules combine with the deodorizing solution.
