在工农业生产、污水处理、垃圾处理和堆肥等过程中，会产生大量的臭气和有机废气，不但对周围环境造成污染，同时对人体健康和生态环境造成严重危害，臭气和有机废气的治理越来越受到人们的关注。In the process of industrial and agricultural production, sewage treatment, garbage treatment and composting, a large amount of odor and organic waste gas will be generated, which will not only pollute the surrounding environment, but also cause serious harm to human health and ecological environment, odor and organic waste gas. Governance is getting more and more attention.
在有机废弃物发酵过程中，微生物通过代谢活动，把其中一部分有机物氧化成简单的无机物，为生物生命活动提供所需的能量，另一部分有机物转化为生物体所需的营养物质，形成新的细胞体，使微生物不断增殖，在此过程中，放出大量能量，除小部分为细胞质合成提供能量外，其余均以热量的形式放出，据文献介绍，在有机废弃物高温发酵阶段，微生物氧化分解有机废弃物平产生的热量约420kJ/kg，这些热能随臭气排出，使臭气温度最高可达60～70℃，同时，由于物料堆体温度升高，导致物料水分蒸发速度加快，大量水分也随臭气排出。In the process of organic waste fermentation, microorganisms oxidize some of the organic matter into simple inorganic substances through metabolic activities, providing the required energy for biological life activities, and converting another part of organic matter into nutrients required by the organism to form new ones. In the process of the cell body, the microorganisms continue to proliferate. In the process, a large amount of energy is released, except for a small part that provides energy for cytoplasmic synthesis, and the rest is released in the form of heat. According to the literature, in the high-temperature fermentation stage of organic waste, microbial oxidative decomposition The organic waste produces about 420kJ/kg of heat, which is discharged with the odor, so that the odor temperature can reach 60~70°C. At the same time, due to the increase of the temperature of the material pile, the evaporation rate of the material is accelerated, and a large amount of water is generated. Also discharged with the odor.
矿质原料如煤炭、柴油等在燃烧过程中不可避免地产生烟尘等颗粒物、一氧化碳(CO)、二氧化硫(SO2)和氮氧化物(NOx)等有毒有害气体，同时，燃烧尾气也会带走大量热量，而这部分热量未经利用，造成热能的浪费，加剧对环境的污染。Mineral raw materials such as coal and diesel oil inevitably produce particulate matter such as smoke, carbon monoxide (CO), sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) in the combustion process. At the same time, the combustion exhaust gas will also be taken away. A lot of heat, and this part of the heat is not used, causing waste of heat energy and increasing pollution to the environment.
治理臭气和有机废气的技术有很多，如吸收吸附、焚烧法、化学转化法、冷凝法及生物法等，但在这些方法中，最为经济有效的是生物除臭法，生物除臭法是一种无臭化、无害化的工艺方法，即利用具有除臭功能的微生物菌群转化废气中的硫化氢、还原硫化物等臭气物质，具有去除率高，运转费用低，操作管理简单， 不产生二次污染等优点，但是，生物除臭法除臭效果依赖除臭微生物的活性，除臭进气温度过高或过低都会影响微生物的生长繁殖，进而降低除臭效果，当除臭进气温度高于40℃或低于15℃时，除臭微生物生长繁殖受到抑制；当除臭进气温度高于60℃时，除臭微生物大量死亡，丧失除臭效果。There are many technologies for controlling odor and organic waste gas, such as absorption and adsorption, incineration, chemical conversion, condensation, and biological methods. However, among these methods, the most economical and effective one is biological deodorization. The biological deodorization method is A odorless and harmless process method, which utilizes a microbial flora having a deodorizing function to convert odorous substances such as hydrogen sulfide and reduced sulfide in exhaust gas, has high removal rate, low running cost, and simple operation and management , It does not produce secondary pollution. However, the deodorizing effect of biological deodorization depends on the activity of deodorizing microorganisms. Deodorizing the intake air temperature is too high or too low, which will affect the growth and reproduction of microorganisms, thereby reducing the deodorizing effect and deodorizing. When the intake air temperature is higher than 40 ° C or lower than 15 ° C, the growth and reproduction of the deodorizing microorganism is inhibited; when the deodorizing air inlet temperature is higher than 60 ° C, the deodorizing microorganisms die in large amounts, and the deodorizing effect is lost.

有益效果：Beneficial effects:
本发明充分考虑有机废弃物发酵臭气热量高、湿度大的特点，创造性地设计一种换热冷凝器，换热冷凝器内均匀竖直排列中若干个换热管，换热管内含热臭气与管外的新鲜空气对流，通过换热管进行充分地热交换，该方式与传统换热方式相比，换热比表面积大，换热效率高，同时，新鲜空气经换热冷凝器加热成热空气，热空气可以作为有机废弃物的热源，对有机废弃物进行加热、供氧，缩短有机废弃物发酵升温时间，提高发酵效率。The invention fully considers the characteristics of high odor of organic waste fermentation odor and high humidity, and creatively designs a heat exchange condenser, and several heat exchange tubes are uniformly arranged in the heat exchange condenser, and the heat exchange tube contains hot odor. The gas is convected with the fresh air outside the pipe, and is fully exchanged by the heat exchange tube. Compared with the conventional heat exchange mode, the heat exchange has a large specific surface area and high heat exchange efficiency, and at the same time, the fresh air is heated by the heat exchange condenser. Hot air and hot air can be used as a heat source for organic waste to heat and supply organic waste, shorten the heating time of organic waste fermentation, and improve fermentation efficiency.
由于有机废弃物发酵臭气湿度大，在经换热冷凝器降温的同时，也产生了大量大量冷凝水，这些冷凝水经换热管自然汇集到换热冷凝器的下端盖内，当冷凝水 液位达到一定高度时，由于压差的作用，冷凝水随U型管自然外排至沟渠中，这种方式操作简单易行，同时利用冷凝水密封下端盖冷凝水排水口，防止冷凝后的臭气经下端盖冷凝水排水口排向大气造成二次污染。Due to the high humidity of the organic waste fermentation odor, a large amount of condensed water is also generated while being cooled by the heat exchange condenser, and the condensed water is naturally collected into the lower end cover of the heat exchange condenser through the heat exchange tube, when the condensed water When the liquid level reaches a certain height, due to the pressure difference, the condensed water is naturally discharged into the ditch along with the U-shaped pipe. This method is simple and easy to operate, and the condensed water drain port of the lower end cover is sealed by the condensed water to prevent condensation. The odor is discharged to the atmosphere through the lower end cover condensate drain port to cause secondary pollution.
当在冬季进行有机废弃物的好氧发酵，以及好氧发酵伊始，排出的臭气温度低时，无需换热冷凝，本发明创新设计，在换热冷凝器管路上设置旁通支路，当在冬季进行有机废弃物的好氧发酵，以及好氧发酵伊始，排出的臭气温度低时，低温臭气经过旁通支路进入生物除臭装置，以避免低温臭气经过换热冷凝器再次降温；而当在有机废弃物的好氧发酵的高温阶段，排出的臭气温度高、湿度大，此时关闭旁通支路，臭气通过换热冷凝器降温，使生物除臭滤塔内物料温度始终保持在限定的范围内，既保证除臭效果，又使生物除臭滤塔中的微生物不至于休眠和死亡。When the aerobic fermentation of organic waste is carried out in winter, and the temperature of the discharged odor is low at the beginning of aerobic fermentation, heat exchange condensation is not required, and the invention is innovatively designed to provide a bypass branch on the heat exchanger condenser line. In the winter, the aerobic fermentation of organic waste, and the beginning of aerobic fermentation, when the odor temperature is low, the low-temperature odor enters the biological deodorization device through the bypass branch to avoid the low-temperature odor passing through the heat exchange condenser again. Cooling; while in the high temperature stage of aerobic fermentation of organic waste, the odor of the discharged odor is high and the humidity is high. At this time, the bypass branch is closed, and the odor is cooled by the heat exchange condenser to make the biological deodorizing filter tower The temperature of the material is always kept within a limited range, which not only ensures the deodorizing effect, but also prevents the microorganisms in the biological deodorizing filter tower from sleeping and dying.
本发明既节能，又环保，真正实现污染治理与能源循环利用的和谐统一。The invention not only saves energy but also protects the environment, and truly realizes the harmonious unification of pollution control and energy recycling.
