【引言】
在环保常态化巡查的当下,规模化养鸡场的核心风险早已不只是粪污脱水难。一旦粪污处理环节异味扩散、粉尘无组织飘散,极易收到周边群众投诉,面临限期整改、罚款,严重时直接停产。金万泓卧式闪蒸鸡粪烘干机采用闭环烘干工艺,从源头管控臭气与粉尘,帮助养殖场化解环保压力,稳定通过环评验收,实现粪污资源化合规生产。
Against the backdrop of regular environmental inspections, the core risks facing large-scale chicken farms extend far beyond difficulties in manure dewatering. Once odours spread and dust drifts without containment during manure treatment, complaints from nearby residents will quickly follow, bringing rectification deadlines, fines and even production shutdowns in serious cases. The Jinwanhong horizontal flash evaporation chicken manure dryer adopts a closed-loop drying process to control odour and dust at the source. It helps breeding farms ease environmental compliance pressure, smoothly pass EIA acceptance and realise compliant production for manure resource utilisation.

一、当下养殖行业最大难题:烘不干是小事,异味扩散、粉尘飘溢被举报关停才是大麻烦
很多养殖场前期只关注鸡粪能不能烘干,却忽略废气异味管控,埋下巨大隐患。鲜鸡粪有机质高,堆放、烘干过程持续释放氨气、硫化氢等恶臭气体,伴随粉尘飘散。环保监管重点核查三项:粪污是否露天堆放、烘干工序有无无组织废气、渗滤液是否管控。一旦出现异味扰民投诉,监管部门会快速到场核查。即便设备可以把鸡粪烘干,只要臭气外溢、粉尘超标,依然会判定不合规,面临停产整改。不少养殖场改造误区:只上烘干主机,尾气除臭配套简化,投产之后才发现异味问题无法解决,后期追加环保改造,投入更多资金。
I. Top Industry Challenge Today: Poor Drying Performance Is Minor; Odour Diffusion and Dust Emissions May Trigger Reports and Shutdowns
Many farms only focus on whether chicken manure can be dried in the early stage while ignoring waste gas and odour control, creating major hidden risks. Fresh chicken manure is high in organic matter and continuously releases malodorous gases such as ammonia and hydrogen sulphide alongside drifting dust during stockpiling and drying.
Environmental inspectors prioritise three checks: whether manure is stockpiled in the open air, whether unorganised emissions occur during drying, and whether leachate is properly managed. Once odour nuisance complaints arise, regulators carry out on-site inspections rapidly. Even if the equipment successfully dries chicken manure, the operation will still be deemed non-compliant and ordered to stop production for rectification if odour escapes or dust exceeds limits.
A common transformation pitfall among farms: installing only the main drying unit while simplifying tail-gas deodorisation accessories. Operators then discover odour issues cannot be resolved after commissioning and have to invest extra funds in subsequent environmental retrofits.
二、传统开放式滚筒烘干弊端:臭气漫天、蚊虫滋生,环评验收难以通过
传统滚筒烘干设备普遍存在密封短板,筒体两端、法兰位置容易漏风。
1.筒体半开放结构,烘干过程中氨气、硫化氢等恶臭气体直接逸散到车间与厂区,顺风扩散到周边村落,极易引发居民投诉;
2.鸡粪在筒内长时间翻滚,高温发酵持续释放臭气,筒壁粘料长期堆积,变成持续异味源头;车间粉尘飞扬,蚊虫大量滋生;
3.尾气处理仅简单配套基础除尘,缺少除臭单元,尾气排放指标很难稳定达标,环评验收通过率低。很多项目就算勉强投产,常年处在环保督查风险之下,生产提心吊胆。
II. Drawbacks of Traditional Open Rotary Drying: Severe Odour, Pest Breeding and Low EIA Pass Rate
Conventional rotary dryers generally suffer sealing defects, with air leakage easily occurring at both cylinder ends and flange joints.
The semi-open cylinder structure allows malodorous gases including ammonia and hydrogen sulphide to escape directly into workshops and plant areas, drifting downwind to neighbouring villages and frequently triggering resident complaints.
Chicken manure tumbles for a long time inside the cylinder, and continuous high-temperature fermentation releases persistent odours. Material caked on cylinder walls forms permanent odour sources. Workshops are filled with dust and become breeding grounds for insects.
Tail-gas treatment is limited to basic dust removal without dedicated deodorisation units, making stable compliance of exhaust indicators difficult and lowering EIA acceptance chances. Even projects that barely go into production operate under constant environmental inspection risks.
三、金万泓卧式闪蒸全密闭负压烘干系统核心技术详解
金万泓卧式闪蒸整套产线采用全密闭负压闭环设计,整套设备从原料进料、主机烘干到尾气收集全程封闭。引风机持续在系统内部形成稳定负压,系统内部气压低于外部大气压,臭气、粉尘只会被吸入尾气管道,不会向外溢出到车间。湿鸡粪通过密闭螺旋输送进入主机,全程不接触外界空气;主机筒体法兰、检修口、软连接全部采用耐腐密封件,杜绝缝隙跑气。整套系统形成独立闭环,把异味牢牢锁在设备管路内部集中处理,从结构上杜绝无组织排放。
III. Core Technology of Jinwanhong Fully Sealed Negative-pressure Horizontal Flash Drying System
The complete Jinwanhong horizontal flash evaporation line features a fully sealed negative-pressure closed-loop design. The entire system remains enclosed from raw material feeding and main-unit drying through tail-gas collection.
An induced draft fan maintains stable negative pressure inside the system, where internal pressure stays lower than atmospheric pressure. Odour and dust are drawn into the exhaust pipeline instead of leaking out into workshops. Wet chicken manure enters the main unit via a sealed screw conveyor with zero exposure to ambient air. Corrosion-resistant seals are fitted on cylinder flanges, access doors and flexible connections to eliminate air leakage through gaps. The independent closed loop locks odour inside pipelines for centralised treatment and structurally eliminates unorganised emissions.
四、高温闪蒸快速分解臭味分子,配套专业除尘除臭系统,车间无异味、厂区无污染
工艺上双重除臭,同步处理粉尘与恶臭分子:
1.高温瞬时闪蒸除臭:鸡粪进入卧式闪蒸主机,高温热风瞬时作用,快速分解大部分蛋白质腐败产生的恶臭分子,杀灭虫卵、有害致病菌,大幅削减臭气产生量;
2.后端尾气深度净化:烘干尾气依次经过旋风除尘、布袋除尘,去除固体粉尘;再进入除臭装置,对氨气、硫化氢等残余恶臭气体进一步净化,尾气达标后再高空排放。车间内部闻不到明显粪污臭味,厂区无粉尘飘散,无渗滤液产生,彻底消除异味扰民根源。
IV. High-temperature Flash Evaporation for Rapid Odour Molecule Decomposition + Specialised Dust and Odour Removal System: Odour-free Workshops and Pollution-free Plant Zones
Dual deodorisation is implemented in the process to treat dust and malodorous molecules simultaneously:
High-temperature instant flash deodorisation: When chicken manure enters the horizontal flash main unit, instant high-temperature hot air decomposes most odour molecules generated by protein putrefaction, kills insect eggs and harmful pathogenic bacteria and drastically cuts odour generation.
Advanced tail-gas purification at downstream stage: Drying exhaust passes through cyclone dust collectors and baghouse filters sequentially to remove solid dust before entering deodorisation equipment for further purification of residual malodorous gases such as ammonia and hydrogen sulphide. Exhaust is released at height only after meeting emission standards.
No obvious manure odour can be detected inside workshops, no dust drifts across the plant site and no leachate is produced, fundamentally removing the root cause of odour nuisance.
五、高湿鸡粪直接进料,不粘壁、不堵机,支持全天候24 小时不间断连续生产
环保达标,同时兼顾连续稳定生产。卧式闪蒸动态流化工艺,70%-80% 含水率高湿鲜鸡粪可直接上机,无需前置固液分离压榨。 物料在热风当中悬浮打散,不易粘壁结块,减少筒壁积料持续发酵发臭的问题,降低停机清理频次。整套自动化产线支持 24 小时连续运行,适合大型规模化鸡场不间断产出粪污的工况,不会因为频繁停机清料造成粪污堆积、异味反弹。
V. Direct Feeding of High-moisture Chicken Manure, Anti-sticking and Anti-blocking, Supporting Non-stop 24-hour Continuous Production
While meeting environmental standards, the system delivers stable continuous production. With a dynamic fluidisation flash process, it directly processes fresh chicken manure at 70%–80% moisture without pre-treatment via solid-liquid separation and pressing.
Materials are suspended and dispersed in hot air, resisting wall adhesion and caking. This reduces persistent odour from accumulated material fermenting on cylinder walls and cuts the frequency of shutdowns for cleaning. The automated full line supports round-the-clock continuous operation, matching the steady manure output of large-scale chicken farms. Frequent shutdowns for material clearing and the resulting manure accumulation and odour rebound are avoided.
六、烘干成品干燥松散、无臭味,有机质达标,直接用作有机肥生产原料
经过高温闪蒸无害化处理后的干鸡粪,成品松散干爽,本身不再散发浓烈粪臭味,含水率稳定可控。物料保留有效有机质,无害化指标满足畜禽粪污还田相关标准,既可以直接作为有机肥厂原料外销,也可场内配套造粒生产线加工商品有机肥。粪污不再是需要花钱清运、带来环保风险的废弃物,转化成合规可销售资源化产品,实现环保达标 + 增收双重目标。
VI. Loose, Odour-free Dried Output with Qualified Organic Matter, Directly Usable as Organic Fertiliser Feedstock
Dried chicken manure after harmless high-temperature flash treatment is loose, dry and free of strong manure odour, with stably controllable moisture content. It retains available organic matter and meets harmlessness standards for livestock and poultry manure returning to farmland. It can either be sold directly as feedstock for organic fertiliser plants or connected to on-site granulation lines to produce commercial organic fertiliser.
Manure is transformed from waste requiring paid haul-away and carrying environmental risks into a compliant, saleable recycled product, achieving dual goals of environmental compliance and extra revenue.
