Description
技术领域technical field
本发明涉及恶臭气体处理技术领域，具体地涉及一种超高效智能型复合式恶臭气体处理装置。The invention relates to the technical field of malodorous gas treatment, in particular to an ultra-efficient intelligent compound malodorous gas treatment device.
背景技术Background technique
恶臭气体污染是指一切刺激嗅觉器官引起人们不愉快及损害生活环境的气体物质，作为一种典型的环境公害已为世界各国所公认，不少发达国家将其作为一种单列公害进行研究，并专项立法实施防治。近年来，我国越来越重视对恶臭的监测与防治，人们生活对环境友好的需求越来越强烈。Odor gas pollution refers to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. As a typical environmental pollution, it has been recognized by all countries in the world. Legislative implementation of prevention and control. In recent years, my country has paid more and more attention to the monitoring and prevention of stench, and people's demand for environmental friendliness has become stronger and stronger.
城市污水处理厂、污水泵站、污泥处理厂、污泥和垃圾填埋场、垃圾转运站、垃圾处理厂、粪便处理厂、养殖厂、屠宰厂等常年超标释放诸如硫化氢、氨、甲硫醇、甲硫氢、三甲胺、甲硫醚、二甲二硫、二硫化碳和苯乙烯等恶臭气体污染周边环境，厂群矛盾突出，投诉不断，导致地块贬值，投资价值受到严重影响。Urban sewage treatment plants, sewage pumping stations, sludge treatment plants, sludge and landfills, garbage transfer stations, garbage treatment plants, feces treatment plants, breeding plants, slaughterhouses, etc. release excessive emissions such as hydrogen sulfide, ammonia, and formazan all year round. Odor gases such as mercaptan, methyl sulfide, trimethylamine, methyl sulfide, dimethyl disulfide, carbon disulfide, and styrene pollute the surrounding environment. The contradictions between the factories and the group are prominent, and complaints continue, which leads to the depreciation of the land and the investment value is seriously affected.
在已有的臭气治理行业中，单一除臭工艺和设备较多，如生物除臭、洗涤除臭、活性炭吸附、光解除臭等，单一除臭设备的除臭效率有限，一般在99%以下且运行多缺乏稳定性。而实践表明部分恶臭释放场所加盖封闭后臭气浓度（恶臭气体用无臭清洁空气进行稀释到刚好无臭时所需的稀释倍数)甚至高于100万，既使把臭气浓度去除99%，仍为10000，对照国家标准，污染厂界仍很难达标，这就从一方面解释了为何污水处理厂等污染场所多数设置了除臭装置，厂群矛盾依旧突出的问题。In the existing odor control industry, there are many single deodorization processes and equipment, such as biological deodorization, washing deodorization, activated carbon adsorption, photo deodorization, etc. The deodorization efficiency of a single deodorization equipment is limited, generally at 99% Below and more lack of stability in operation. However, practice shows that the odor concentration (the dilution factor required when the odor gas is diluted with odorless clean air to just odorless) is even higher than 1 million, even if the odor concentration is removed by 99%. , is still 10,000. Compared with the national standard, it is still difficult for polluting factories to meet the standard. This explains why most polluted places such as sewage treatment plants have deodorization devices, and the contradiction between factories and groups is still prominent.
因此，如何有机整合臭气治理多种工艺，发明一种超高效除臭复合成套装置，臭气浓度去除率达到99.99%以上，便具有突出的意义。当然，目前也有将不同除臭技术手段融合实现复合除臭的设备诞生，但大都结构及功能布置不合理，在气体排放各项指标上难以突破，稳定性不足，很难适应不同季节天气臭气源强浓度的波动，运行方式也缺乏灵活机动性。Therefore, how to organically integrate multiple processes of odor control and invent a super-efficient deodorization composite complete device with a removal rate of more than 99.99% of odor concentration is of outstanding significance. Of course, there are also devices that combine different deodorization techniques to achieve composite deodorization, but most of them have unreasonable structures and functional arrangements, and it is difficult to make breakthroughs in various indicators of gas emissions. The stability is insufficient, and it is difficult to adapt to different seasons of weather and odor. The source strength and concentration fluctuate, and the operation mode also lacks flexibility.

正常运行时，恶臭气体自进气管首先进入洗涤除臭塔洗涤处理然后进入生物除臭滤池生物降解最后进入光解除臭装置净化处理，由于臭气浓度逐级衰减，实测洗涤除臭、生物除臭、光解除臭各级除臭效率分别为99%、95%、80%，总除臭效率为99.99%。During normal operation, the malodorous gas first enters the washing and deodorizing tower from the intake pipe for washing treatment, then enters the biological deodorization filter for biodegradation, and finally enters the light deodorization device for purification treatment. Due to the gradual decay of the odor concentration, the measured washing deodorization, biological deodorization The deodorization efficiencies of odor and light deodorization levels are 99%, 95%, and 80% respectively, and the total deodorization efficiency is 99.99%.
进气管入口和排放单元出气口处的在线硫化氢浓度测试仪等在线仪表上传数据至电控单元，电控单元根据装置净化前后气体的浓度，灵活调配第一风量控制阀、第二风量控制阀及第三风量控制阀的开启角度，使得装置的运行模式切换为洗涤除臭+生物除臭+光解除臭、洗涤除臭+生物除臭、生物除臭+光解除臭、洗涤除臭+光解除臭、单独洗涤除臭、单独生物除臭或单独光解除臭处理；若排放单元出气口处的在线硫化氢浓度测试仪检测到气体未达到排放标准，则由电控单元控制三通分流阀将未达标气体输送至进气管的入口，重新进行处理。Online instruments such as the online hydrogen sulfide concentration tester at the inlet of the intake pipe and the outlet of the exhaust unit upload data to the electronic control unit, and the electronic control unit flexibly deploys the first air volume control valve and the second air volume control valve according to the gas concentration before and after purification of the device And the opening angle of the third air volume control valve, so that the operation mode of the device is switched to washing deodorization + biological deodorization + light deodorization, washing deodorization + biological deodorization, biological deodorization + light deodorization, washing deodorization + light deodorization Deodorization, separate washing deodorization, separate biological deodorization or separate light deodorization treatment; if the online hydrogen sulfide concentration tester at the gas outlet of the discharge unit detects that the gas does not meet the discharge standard, the three-way diverter valve will be controlled by the electronic control unit Send the non-standard gas to the inlet of the intake pipe for reprocessing.
