Description

一种在线循环再生有机废气处理方法与装置 技术领域  Online recycling and regenerating organic waste gas treatment method and device
[0001] 本发明涉及循环再生有机废气处理, 尤其涉及一种在线循环再生有机废气处理 方法与装置。  [0001] The present invention relates to recycling organic waste gas treatment, and more particularly to a method and apparatus for recycling organic waste gas in an on-line cycle.
背景技术  Background technique
[0002] 城市大气雾霾和臭氧超标是我省面临的重大环境污染问题, 而 VOCs是其形成 重要前体物, VOCs不仅种类繁多, 而且多数有毒, 部分致癌, 严重地污染环境 和危害人类健康。 随着经济的快速发展, 有机废气 (VOCs) 污染日益严重, 并 且潜排潜力巨大, 推进其治理被列入国家大气污染防治重点工作。  [0002] Urban atmospheric haze and ozone exceeding the standard are major environmental pollution problems faced by our province, and VOCs are important precursors. VOCs are not only diverse, but also most toxic, partially carcinogenic, seriously polluting the environment and endangering human health. . With the rapid development of the economy, the pollution of organic waste gas (VOCs) is becoming more and more serious, and the potential for snorkeling is huge. The promotion of its governance has been included in the national key work of air pollution prevention and control.
[0003] 目前治理工业有机废气的方法主要有吸收法、 冷凝法、 催化燃烧、 吸附 -回收 法、 生物法和等离子体法等。 其中吸附-吸收法具有较好的处理效果, 并且在吸 附后可将高附加值的有机物分离回收, 因此受到人们的广泛关注。  [0003] At present, methods for controlling industrial organic waste gas mainly include absorption method, condensation method, catalytic combustion, adsorption-recovery method, biological method and plasma method. Among them, the adsorption-absorption method has a good treatment effect, and after the adsorption, the high value-added organic matter can be separated and recovered, and thus has been widely concerned.
[0004] 传统的吸附 -回收工艺采用将活性炭等多空材料作为吸附剂, 将吸附剂放入固 定床中, 将有机废气通过床层使有机物得到吸附, 后利用热空气或高温水蒸汽 等作为脱附介质通过吸附剂床层, 使吸附后的高浓度有机物在高温作用下脱附 下来, 再经过冷凝、 分离等方式使有机物得到回收。 吸附剂对有机气体的吸附 具有"选择性", 选择大分子的被吸附, 小分子的被遗漏。 采用固定床进行有机废 气的吸附分离, 具有吸附剂机械磨损小、 结构相对简单等优点。 但有以下缺点  [0004] The conventional adsorption-recovery process uses a porous material such as activated carbon as an adsorbent, puts the adsorbent into a fixed bed, passes the organic waste gas through the bed to adsorb the organic matter, and then uses hot air or high-temperature steam as the adsorbent. The desorbing medium passes through the adsorbent bed to desorb the high concentration organic matter after adsorption under high temperature, and then the organic matter is recovered by condensation, separation and the like. The adsorbent has a "selectivity" for the adsorption of organic gases, and the selected macromolecules are adsorbed, and the small molecules are missed. The adsorption and separation of organic waste gas by a fixed bed has the advantages of small mechanical wear of the adsorbent and relatively simple structure. But has the following disadvantages
[0005] (1) 固定床局部"过热" 吸附过程是一个放热过程, 可能会由于吸附热的过 度释放或固定床传热效果不佳, 造成固定床局部"过热", 甚至造成活性炭类吸附 剂起火燃烧。 [0005] (1) Partial "overheating" of the fixed bed The adsorption process is an exothermic process, which may result in excessive "heating" of the fixed bed due to excessive release of heat of adsorption or poor heat transfer of the fixed bed, and even adsorption of activated carbon. The agent burns on fire.
[0006] (2) 压降过大 固定床中吸附剂颗粒排列紧密, 造成有机废气压降过大, 从 而限制了流速, 使大风量的有机废气处理量降低。  [0006] (2) Excessive pressure drop The adsorbent particles in the fixed bed are closely arranged, resulting in an excessive pressure drop of the organic exhaust gas, thereby limiting the flow rate and reducing the amount of organic exhaust gas treated by a large amount of air.
[0007] (3) 易出现"沟流" 对于吸附床中堆积较为松散的区域, 气流会优先通过而 形成"沟流", 使吸附床过早穿透, 部分吸附剂不能和有机废气充分接触, 造成吸 附效率的降低。 [0007] (3) Prone to "channel flow" For areas with loose deposits in the adsorption bed, the airflow will preferentially pass through to form a "channel flow", allowing the adsorption bed to penetrate prematurely, and some adsorbents cannot be in full contact with the organic exhaust gas. Cause suction Reduced efficiency.
[0008] 传统的脱附方法是利用热空气吹风脱附等方法, 具有简单易行等优点, 但同吋 有以下缺点: 富集的有机废气又被混入空气; 后续处理繁琐; 能耗高等。  [0008] The conventional desorption method utilizes hot air blowing desorption and the like, and has the advantages of being simple and easy to operate, but the same disadvantages are obtained: the enriched organic exhaust gas is mixed into the air; the subsequent processing is cumbersome; the energy consumption is high.
技术问题  technical problem
[0009] 本发明的目的在于克服上述固定床"过热"且易出现"沟流"现象的缺点, 提供一 种集吸收、 悬浮式吸附和脱附于一体的在线循环再生有机废气处理方法与装置 , 以达到有效除去有机废气, 无二次污染, 低能耗, 以及避免环境受到污染的 目的。  [0009] The object of the present invention is to overcome the shortcomings of the above-mentioned fixed bed "overheating" and prone to "channeling" phenomenon, and provide an online recycling and regenerating organic waste gas processing method and device integrating absorption, suspension adsorption and desorption In order to achieve effective removal of organic waste gas, no secondary pollution, low energy consumption, and avoid environmental pollution.

发明的有益效果  Advantageous effects of the invention
有益效果  Beneficial effect
[0031] 本发明相对于现有技术, 具有如下的优点及效果:  [0031] Compared with the prior art, the present invention has the following advantages and effects:
[0032] 有机吸收剂溶液、 脱附后的吸附剂颗粒球和有机废气, 由旋流雾化喷嘴以切圆 的方式喷射至旋流塔内充分混合, 并沿着旋流塔内壁周向流动、 螺旋上升。 采 用这种喷射方式, 吸收剂 (吸收剂溶液液滴) 和吸附剂 (吸附剂颗粒球) 从切 圆布置的旋流雾化喷嘴喷射到旋流塔内, 带动有机废气形成周向流动趋势, 使 有机废气与二者充分均匀的混合, 有机废气在旋流塔内螺旋爬升, 增加有机废 气在旋流塔内的运动行程, 延长有机废气在塔内停留吋间, 进一步提高吸收和 吸附效率。 由于有机废气旋流运动, 消除了有机废气贴壁直线上升流动现象。 有机废气中的大分子被吸附, 在上升过程中被吸收剂吸收。 吸收与吸附同吋进 行, 小分子不易被吸附剂吸附, 但能够较好的被吸收剂吸收。 因此, 有机废气 同吋进行二次复合净化大大提高了净化效率。  [0032] The organic absorbent solution, the desorbed adsorbent particle spheres and the organic waste gas are sprayed into the swirling tower by a cyclonic atomizing nozzle to be fully mixed and flowed circumferentially along the inner wall of the swirling tower , spiral rises. With this spraying method, the absorbent (droplet of the absorbent solution) and the adsorbent (the adsorbent particle ball) are sprayed from the swirling atomizing nozzle arranged in the circular circle into the swirling tower to drive the organic waste gas to form a circumferential flow tendency. The organic waste gas is sufficiently uniformly mixed with the two, and the organic waste gas spirally climbs in the swirling tower to increase the movement stroke of the organic waste gas in the swirling tower, prolong the organic waste gas to stay in the tower, and further improve the absorption and adsorption efficiency. Due to the swirling movement of the organic waste gas, the phenomenon that the organic exhaust gas adheres to the straight line is eliminated. The macromolecules in the organic exhaust gas are adsorbed and absorbed by the absorbent during the ascending process. The absorption and adsorption are carried out simultaneously, and the small molecules are not easily adsorbed by the adsorbent, but are better absorbed by the absorbent. Therefore, the secondary composite purification of the organic waste gas with the hydrazine greatly improves the purification efficiency.
[0033] 如上所述。 本发明吸附剂颗粒球像流体一样在旋流塔内悬浮运动。 这种流态化 的特殊运动形式, 使吸附剂颗粒球在塔内以悬浮态与流体接触, 气体和固体相 接触面积较大, 提高了净化效率; 且吸附剂颗粒球在旋流塔内激烈混合, 使旋 流塔内温度和反应物的浓度均匀一致, 可有效避免局部温度过热和浓度过高现 象的发生。  [0033] As described above. The sorbent particles of the present invention float in a swirling tower like a fluid. This special form of fluidization causes the adsorbent particle ball to contact the fluid in a suspended state in the column, and the contact area between the gas and the solid is large, thereby improving the purification efficiency; and the adsorbent particle ball is intense in the swirling tower. Mixing, the temperature in the cyclone tower and the concentration of the reactants are uniform, which can effectively avoid the occurrence of local temperature overheating and excessive concentration.
[0034] 吸附剂颗粒球进行二次生物法脱附, 具有处理效果好、 工艺简单、 能耗低、 投 资少、 无二次污染等优点。  [0034] The sorbent particle ball is subjected to secondary biological desorption, and has the advantages of good treatment effect, simple process, low energy consumption, low investment, no secondary pollution, and the like.
[0035] 本发明将吸附-回收法、 吸收法和生物法集成到一套新装置中, 能够克服传统 净化方法和装置的不足, 实现良好的净化效果。 [0035] The present invention integrates an adsorption-recovery method, an absorption method, and a biological method into a new device, which can overcome the conventional The lack of purification methods and devices achieves a good purification effect.
[0036] 本发明吸附达饱和的吸附剂颗粒球和吸收剂在沉淀池分离后, 分离出的吸收剂 入塔循环使用, 分离出的固体微粒 (吸附剂颗粒球) 排入生物脱附室, 经生物 脱附后, 该固体微粒与吸收剂混合由旋流雾化器再次入旋流塔继续循环使用。 本发明实现了吸附剂的在线循环再生, 提高了净化效率、 降低了运行成本, 简 化了系统清洗及维护, 解决了吸附剂再生效率低的问题。  [0036] After adsorbing the saturated adsorbent particle ball and the absorbent in the present invention, the separated absorbent is recycled into the column, and the separated solid particles (adsorbent particles) are discharged into the biological desorption chamber. After biodesorption, the solid particles are mixed with the absorbent and re-circulated into the cyclone by a cyclone atomizer for further recycling. The invention realizes online recycling of the adsorbent, improves the purification efficiency, reduces the running cost, simplifies the system cleaning and maintenance, and solves the problem of low regeneration efficiency of the adsorbent.
