Ⅰ. Overview and Treatment Process of Feed Waste Gas Deodorization Equipment
During feed production and processing, working procedures such as grinding, fermentation, reactor reaction and high-temperature drying generate a large amount of characteristic waste gas. Mostly white flue gas with high humidity, the waste gas contains grinding smoke, ammonia nitrogen compounds, sulfides and other strongly irritating pollutants. Long-term discharge will seriously pollute the atmospheric environment and reduce the living quality of factory staff and surrounding residents. To help feed enterprises solve odor pollution problems and fulfill environmental responsibilities, Zhonghuan Lvzhou Environmental Protection launches professional feed waste gas deodorization projects adopting the combined process of pretreatment + photocatalytic deodorization, realizing synchronous purification of smoke and odor to achieve compliant discharge.
Ⅱ. Core Treatment Process Flow of Feed Waste Gas
Waste gas source (grinding / fermentation / drying process) → Dust collection hood → Pipeline transportation → Dust removal, cooling and dehumidification equipment (pretreatment) → Photocatalytic deodorization equipment → Induced draft fan → High-altitude compliant discharge
Exclusive Pretreatment Design: Aiming at the characteristics of high humidity and dust content of feed waste gas, the dedicated dust removal, cooling and dehumidification equipment synchronously removes smoke, adjusts temperature and controls humidity. It guarantees stable operation of subsequent photocatalytic equipment and prevents purification efficiency reduction caused by high humidity.
Ⅲ. In-depth Analysis of Feed Waste Gas Treatment Process
This project adopts a stepped treatment mode of pretreatment and core purification. The pretreatment unit optimizes waste gas working conditions, while the photocatalytic unit completely decomposes pollutants, breaking the purification limitations of single treatment technology for complex waste gas.
1. Dust Removal, Cooling and Dehumidification Equipment: Working Condition Optimization
The feed waste gas collected by dust hood firstly enters the pretreatment unit. Multiple filter structures remove grinding smoke particles. Meanwhile, high-efficiency heat exchange and dehumidification modules reduce gas temperature and humidity to avoid condensate generation inside photocatalytic equipment. It ensures adsorption and reaction efficiency of subsequent purification units and improves the overall system stability.
2. Photocatalytic Deodorization Equipment: Complete Odor Decomposition
The pretreated waste gas enters the core reaction area of photocatalytic deodorization equipment. Under high-energy ultraviolet irradiation, multiple purification reactions take place: on the one hand, UV rays directly break the chemical bonds of ammonia nitrogen compounds, sulfides and other pollutants to realize photochemical cracking and degrade contaminants into harmless low-molecular compounds such as carbon dioxide and water; on the other hand, ultraviolet rays generate ozone, which is further converted into highly oxidizing oxygen free radicals to fully oxidize organic pollutants into inorganic substances. Residual ozone also directly oxidizes organic waste, forming dual purification guarantee of direct degradation and indirect oxidation for thorough deodorization.
Ⅳ. Core Advantages of Feed Waste Gas Treatment Equipment
1. Comprehensive and efficient purification: The integrated design of dust removal, dehumidification and deodorization achieves a smoke removal rate of over 95% and an odor elimination rate of over 90%. The odor concentration is stably controlled within 2000 dimensionless units to realize odor-free clean discharge.
2. Adaptable to complex working conditions: Customized for high humidity, dust content and complex components of feed waste gas. The pretreatment unit eliminates adverse effects of high humidity, and the photocatalytic equipment operates stably in multi-component gas, meeting continuous production demands of feed factories.
3. Economical operation cost: The photocatalytic equipment requires no consumables with low energy consumption. The filter materials of pretreatment unit have long replacement cycles. Only regular inspection is required for daily maintenance, effectively reducing enterprise environmental operation costs.
4. Dual compliance guarantee: The process fully meets the secondary standard of Integrated Emission Standard of Air Pollutants (GB16297-1996) and Emission Standards for Odor Pollutants (GB14554-93). No secondary pollution is generated, helping enterprises pass environmental acceptance and daily supervision smoothly.
