Description
技术领域technical field
本发明涉及有机废气处理技术领域，尤其涉及一种有机废气处理设备。The invention relates to the technical field of organic waste gas treatment, in particular to organic waste gas treatment equipment.
背景技术Background technique
目前，国内大部分地区的空气质量不容乐观：夏季臭氧浓度超标、冬季雾霾频发。因而各地纷纷出台防治污染的措施，举全国之力遏制大气污染之势。At present, the air quality in most parts of the country is not optimistic: the ozone concentration exceeds the standard in summer, and the smog occurs frequently in winter. As a result, various places have introduced measures to prevent and control pollution, mobilizing the power of the whole country to curb the trend of air pollution.
VOCs作为臭氧产生的前体物，是有机废气之一。传统采用的有机废气处理技术主要有吸附法、吸收法、燃烧法、等离子法、紫外光解法和生物法，各种技术对消减VOCs排放均有不错的效果，分别适用于不同场合的有机废气的处理，但也存在着各自的不足，具体表现为：VOCs, as the precursors of ozone generation, are one of the organic waste gases. Traditionally used organic waste gas treatment technologies mainly include adsorption method, absorption method, combustion method, plasma method, ultraviolet photolysis method and biological method. Various technologies have good effects on reducing VOCs emissions, and are suitable for organic waste gas in different occasions. However, there are also their own deficiencies, which are specifically manifested in:
(1)吸附法采用活性炭作为吸附剂，活性炭容易因饱和而导致吸附阻力变大，需要频繁更换，其运行费用高，且吸附饱和的活性炭易造成二次污染；(1) The adsorption method uses activated carbon as the adsorbent. Activated carbon is easy to increase the adsorption resistance due to saturation, and needs to be replaced frequently. The operating cost is high, and the saturated activated carbon is easy to cause secondary pollution;
(2)在吸收法中，若采用柴油等矿物油作为吸收剂，由于柴油易燃，吸收剂存在一定安全隐患；若采用表面活性剂作为吸收剂，由于表面活性剂本身吸收效率不高，表面活性剂需进一步处理，易造成二次污染。(2) In the absorption method, if mineral oil such as diesel oil is used as the absorbent, the absorbent has certain safety hazards because the diesel oil is flammable; if a surfactant is used as the absorbent, because the absorption efficiency of the surfactant itself is not high, the surface The active agent needs to be further processed, which is easy to cause secondary pollution.
(3)燃烧法对有机废气的浓度和排放工况要求较高，只适用于处理浓度较高和连续排放的有机废气，对浓度较低的有机废气，需要添加助燃剂，导致成本增加，且设备启动操作繁琐，具有一定的危险性。(3) The combustion method has high requirements on the concentration and emission conditions of organic waste gas, and is only suitable for the treatment of organic waste gas with high concentration and continuous discharge. For organic waste gas with low concentration, it is necessary to add combustion enhancers, resulting in increased costs, and The start-up operation of the equipment is cumbersome and has certain risks.
(4)等离子法和紫外法的降解效率不高，容易产生降解不完全的情况；且在工作过程会产生臭氧，导致臭氧超标。(4) The degradation efficiency of the plasma method and the ultraviolet method is not high, and the situation of incomplete degradation is likely to occur; and ozone will be generated during the working process, causing the ozone to exceed the standard.
(5)传统生物法包括生物洗提、生物滴滤和生物过滤三种技术，其中生物滴滤法使用较为广泛，其原理是：微生物以有机废气为生长碳源和能源，将有机废气氧化为无机物，其降解效率较高。但生物滴滤法也有不足，即微生物的长势不好控制，容易因微生物过多而导致常规陶粒、砾石填料堵塞，阻碍有机废气流通，致使系统的处理效果下降，系统不稳定。(5) The traditional biological method includes three technologies: bioelution, biotrickling and biofiltration. Among them, the biotrickling method is widely used. Inorganic substances have higher degradation efficiency. However, the biological trickling filtration method also has shortcomings, that is, the growth of microorganisms is not easy to control, and it is easy to cause clogging of conventional ceramsite and gravel fillers due to excessive microorganisms, hindering the circulation of organic waste gas, resulting in a decrease in the treatment effect of the system and instability of the system.
有机废气的处理技术的弊端日益突出，已经难以达到严格的环保要求，在新形势下，急需技术改良创新。The disadvantages of organic waste gas treatment technology have become increasingly prominent, and it has been difficult to meet strict environmental protection requirements. Under the new situation, technological improvement and innovation are urgently needed.
又注意到，在废水处理中，新兴了一种高级氧化技术，其利用水力空化原理来获得羟基(OH)：水力空化装置产生的空化泡在溃灭时能产生局部异常高温高压，瞬间可使水分子结合键断裂产生羟基和氢(H)，由于羟基是最活泼的一种活性分子，其几乎能氧化所有的生物大分子、有机物，最终降解成C02、H2O和微量无机盐，实现零废物排放，被人们追捧。It is also noted that in wastewater treatment, an advanced oxidation technology has emerged, which uses the principle of hydraulic cavitation to obtain hydroxyl (OH): the cavitation bubbles generated by the hydraulic cavitation device can produce local abnormal high temperature and high pressure when they collapse. It can instantly break the bonds of water molecules to produce hydroxyl and hydrogen (H). Since hydroxyl is the most active active molecule, it can oxidize almost all biological macromolecules and organic substances, and finally degrade into CO 2 , H 2 O and trace amounts Inorganic salt, to achieve zero waste discharge, is sought after by people.

运行本发明的设备时，有机废气被送入进气段2，在塔中自然上升。当有机废气流经生物段3时，被生物段3中的微生物降解为无机物，降解后的气体上升至除雾器，其水分被除雾器中的吸水填料51抽走，从而变成干燥气体，并从塔顶的出气口排出。在这个过程中，循环水泵6不断将储水槽11中的水搬运至第一喷头41和第二喷头22中，由第一喷头41和第二喷头22均匀喷出，使得储水槽11中的微生物得以在生物填料31上挂膜。同时，也将储水槽11中的羟基喷淋在生物填料31上，利用羟基的高活性、高氧化性的特质，对生物填料31上的微生物进行降解，以抑制微生物的繁殖速度，解决因微生物繁殖过快而导致的填料堵塞问题。需要说明是的，由于生物填料31的底部先接触有机废气，生物填料31的底部先开始进行降解，从而大量堆积微生物，生物填料31的底部最容易发生堵塞，故用专门设置第二喷头22对着生物填料31的底部喷淋，来抑制底部的微生物繁殖。When the device of the present invention is in operation, the organic waste gas is sent into the intake section 2 and rises naturally in the tower. When the organic waste gas flows through the biological section 3, it is degraded into inorganic substances by the microorganisms in the biological section 3, and the degraded gas rises to the demister, and its moisture is sucked away by the water-absorbing filler 51 in the demister, thereby becoming dry The gas is discharged from the gas outlet at the top of the tower. In this process, the circulating water pump 6 continuously transports the water in the water storage tank 11 to the first nozzle 41 and the second nozzle 22, and is sprayed evenly by the first nozzle 41 and the second nozzle 22, so that the microorganisms in the water storage tank 11 It is possible to hang a film on the biological filler 31 . At the same time, the hydroxyl group in the water storage tank 11 is also sprayed on the biological filler 31, and the microorganisms on the biological filler 31 are degraded by using the high activity and high oxidation properties of the hydroxyl group, so as to inhibit the reproduction speed of the microorganism and solve the problem caused by microorganisms. Plugging problem caused by too fast breeding. It needs to be explained that because the bottom of the biological filler 31 first contacts the organic waste gas, the bottom of the biological filler 31 first begins to degrade, thereby accumulating a large number of microorganisms, and the bottom of the biological filler 31 is most likely to be blocked, so the second spray nozzle 22 is specially arranged to Spray the bottom of the biological filler 31 to suppress the reproduction of microorganisms at the bottom.

当然，塔中废气的气液接触方式不一定要是本实施例中的逆流式(从下往上)，也可根据实际情况选择为并流式或顺流式。Certainly, the gas-liquid contact mode of the waste gas in the tower does not necessarily have to be the counter-current type (from bottom to top) in this embodiment, and can also be selected as a parallel-current type or a parallel-current type according to actual conditions.
进一步地，在循环水泵6的出水管道中串接一个流量计7来统计喷淋的水流量，有机废气处理设备中的电控装置据此水流量来控制有机废气的进气速度，使塔中气速为0.1～0.5m/s，有机废气在塔中的停留时间为5～60s，以确保有机废气被充分降解。Further, a flow meter 7 is connected in series in the outlet pipe of the circulating water pump 6 to count the sprayed water flow, and the electronic control device in the organic waste gas treatment equipment controls the intake speed of the organic waste gas according to the water flow, so that the tower The gas velocity is 0.1-0.5m/s, and the residence time of the organic waste gas in the tower is 5-60s to ensure that the organic waste gas is fully degraded.
