本实施例在实施时，通过进风组件100抽排进风，将废气抽排进入VOC废气处理净化装置；废气在第一导向组件400的作用下导向至除尘组件200去除废气中的颗粒物，随后废气在的第二导向组件500的作用下导向至分子筛净化组件300进行净化处理输出净化空气；吸附有VOC的分子筛301经加热脱附、冷凝处理后由输送组件600回送至分子筛循环组件中复用，同时VOC燃烧分解。
如图1所示，进风组件100包括排风口101及排风风机102，排风口101设于壳体的底部，排风风机102设于排风口101的上方，第一导向组件400设于排风风机102的上方。烤漆房等设备中常采用顶部进风、地台110抽排出风的方式，废气在排风风机102的作用下由排气口进入VOC废气处理净化装置中，在第一导向组件400的导向作用下流向除尘组件200进行除尘处理。
如图1所示，除尘组件200包括泡沫剂储存器201、增压泵202、泡沫发生器203以及网状泡沫夹板204，增压泵202设有与泡沫剂储存器201连通的进水管及与泡沫发生器203连通的出水管，泡沫发生器203与网状泡沫夹板204间通过泡沫导管205连通；网状泡沫夹板204的上方设有用于滤去水雾的过滤水板206，第二导向组件500设于过滤水板206的上方。在实施时，增压泵202抽取泡沫剂储存器201中的泡沫剂，经过泡沫发生器203产生泡沫，泡沫经泡沫导管205流进网状泡沫夹板204，废气气流通过泡沫的除尘作用除去粉尘，气流通过过滤水板206滤去水雾，滤去水雾后的气流在第二导向组件500的导向作用下流向分子筛净化组件300。但需要说明的是，本实施例的除尘组件200并不限于上述的泡沫除尘等的湿式除尘方式，其他如过滤棉、过滤袋等干式除尘方式均适用于本发明。
如图2、图3所示，分子筛净化组件300包括多层网状板302，相邻的网状板302之间形成有夹缝结构303，分子筛301盛装于夹缝结构303中；气流流经分子筛净化组件300，分子筛301吸附气流中VOC、水分等物质，实现废气的净化。其中，分子筛净化组件300一侧设有风循环组件，风循环组件包括净化风通道304、进风风机305及导风管道306，净化风通道304连接于网状板302和进风风机305之间，导风管道306连接于进风风机305的出风口。分子筛净化组件300的出风在进风风机305的作用下，由净化风通道304流入导风管道306，本实施例可通过设置导风管道306的位置和构造将净化空气循环至烤漆房等设备 中重复使用进入再循环。
如图2所示，图中箭头表示气流流向，排风口101、排风风机102、第一导向组件400、第二导向组件500、净化风通道304、进风风机305及导风管道306形成本实施例的主要风循环系统，且废气在主要风循环系统的作用下流经除尘、除水雾及去除VOC实现空气净化，且净化空气导入设备中作为循环风使用后进入下一个循环，如此循环往复，能够实现零排放。
分子筛301吸附水分、VOC后需经加热脱附处理才能够重复利用，本实施例将吸附有VOC的分子筛301经加热脱附、冷凝后输送至分子筛净化组件300中，实现分子筛净化组件300中分子筛301的动态更换，保证分子筛301的净化效果。分子筛循环组件的具体结构如下：
如图3所示，分子筛净化组件300的下方设有第一导轨307，第一导轨307与夹缝结构303连通且第一导轨307靠近输入端的一端向下倾斜；分子筛净化组件300的上方设有第二导轨308，第二导轨308与夹缝结构303连通且靠近夹缝结构303的一端向下倾斜。吸附有VOC的分子筛301在重力作用下下落，并沿着第一导轨307输送至输入端，并由输送组件600输送至分子筛净化组件300的上方，分子筛301由输出端下落至第二导轨308，并沿着第二导轨308滑向分子筛净化组件300中，从而实现分子筛301的自动循环利用。
其中，输送组件600包括第一输送带601、第二输送带602、第三输送带603及第四输送带604，第一输送带601的一端设于第一导轨307末端的下方，第一输送带601的另一端设于第二输送带602一端的上方，第二输送带602的另一端设于第三输送带603一端的上方，第三输送带603另一端设于第四输送带604一端的上方，第四输送带604的另一端设于第二导轨308始端的上方；多组输送带组成输送组件600，可根据不同的应用场景布置输送组件600节约占用体积；本实施例中，第一输送带601、第二输送带602、第三输送带603及第四输送带604表面均设有若干平行设置的挡板605，防止分子筛301在重力作用下下滑，保证有效输送。为了便于分子筛301的输送，本实施例第一导轨307的末端设置有尺寸收窄的第一出口，第一输送带601和第二输送带602之间设置有出口收窄的第三导轨606，第三输送带603和第四输送带604之间设置有出口收窄的第四导轨607，分子筛301通过第三导轨606由第一输送带601下落至第二输送带602上，分子筛301通过第四导轨607由第二输送带602输送至第三输送带603上。需要 说明的是，第三导轨606和第四导轨607的设置不仅利于分子筛301的输送，还能起到隔热阻风的作用。
加热组件700包括设于第二输送带602上方的加热器701及设于加热器701上方的第一风机702，第一输送带601设于第一热风柜608内且第一输送带601的上方设有第三风机609，第二输送带602及加热组件700设于第二热风柜610内；冷凝组件800包括冷凝器801及第二风机802，第二风机802设于冷凝器801上方，冷凝器801设于第四输送带604上方，第四输送带604部分、冷凝组件800设于第二冷风柜612内，第三输送带603设于第一冷风柜611内，第一冷风柜611、第二冷风柜612之间连通有冷风通道613，第二冷风柜612侧壁设有进风口614。
在第二热风柜610内，加热器701产生的高温空气在第一风机702的吹送作用下对第二输送带602上的分子筛301进行高温吹扫，分子筛301吸附、浓缩的VOC在高温下燃烧生成二氧化碳和水，同时分子筛301吸附的水也在高温下脱附、汽化；为实现较好的脱附效果，本实施例的高温空气的温度范围控制在300℃～350℃，脱附后的分子筛301在第二输送带602的作用下输送至第一冷风柜611，通过冷风通道613从第二冷风柜612中吹送过来的冷气在第一冷风柜611内进行热交换达到初步冷却的作用，初步冷却的分子筛301在第三输送带603的作用下进入第二冷风柜612，冷凝器801产生的冷却空气在第二风机802的吹送作用下进入第二冷风柜612对进入第二冷风柜612的分子筛301进行强制冷却至60℃以下，脱附后的分子筛301可以再次发挥吸附、浓缩的作用，如此循环往复。
实施例二
本实施例为本发明VOC废气处理净化装置的第二实施例，本实施例与实施例一类似，所不同之处在于：本实施例还包括余热回收系统900，用以回收分子筛301脱附过程产生的热量，相比于实施例一，本实施例具有更好的节能性和环保性。
如图4所示，余热回收系统900包括蓄热水箱901以及设于蓄热水箱901内的冷却管902，冷却管902的一端连接于第一热风柜608的底部、冷却管902的另一端连接于第一热风柜608的顶部，第一热风柜608的顶部还与第一冷风柜611连通，第二热风柜610设有连通第二热风柜610顶部和第二热风柜610底部的热回流通道903。具体地，冷却管902的一端与第一热风柜608的底部通过第 一导管904连通，冷却管902的另一端与第一热风柜608的顶部通过第二导管905连通，第一冷风柜611与第一热风柜608顶部通过第三导管906连通。其中，第二导管905上连接有三通阀907，三通阀907的其中两个接口分别与第二导管905连接，三通阀907的另一接口处设有第四风机908，在第四风机908的出风口处设置有热风风道909。本实施例中，冷却管902为蛇形热交换管，需要说明的是，这是为了获得较高的换热效率做出的优选，而并不作为限制性的规定。
第一热风柜608中，在第三风机609的吹送作用下，通过第一输送带601上分子筛301后的余热空气经第一导管904导入蓄热水箱901，余热空气通过冷却管902与蓄热水箱901内的水进行热交换，将多余热量储存在蓄热水箱901中，此为第一路余热回收。
第二热风柜610中，在第一风机702的吹送作用下，高温空气对第二输送带602上的分子筛301进行高温吹扫，热空气由热回流通道903再次进入第二热风柜610中，如此反复循环，此为第二路余热回收。

在第三风机609的吹送作用下，余热空气导入蓄热水箱901，通过冷却管902，调节电动球阀，经过第二导管905的余热空气再次进入第一热风柜608中，如此循环往复，此为第四路余热回收；
当需要进行升温作业时，余热空气导入蓄热水箱901，通过冷却管902，调节电动球阀，使得第二导管905内余热空气由电动球阀排出，在第四风机908的作用下，余热空气由热风风道909排出，此为第五路余热回收；回收的余热可作为升温干燥作业提供热源。
实施例三

本实施例中的烤漆房可设置电控系统用以控制进风组件100、除尘组件200、分子筛净化组件300、输送组件600、加热组件700及冷凝组件800中电控组件的工作进程以控制烤漆房进入不同的工作模式：
常温喷涂作业模式下：控制主要风循环系统开启设定时间后，第一热风柜608中的余热空气通过第一导管904导入蓄热水箱901，余热空气通过冷却管902与与蓄热水箱901中的水进行热交换，将多余热量储存在蓄热水箱中；同时，加热器701及第一风机702启动，在第一风机702的吹送作用下对第二输送带602上的分子筛进行高温吹扫，回流热空气通过热回流通道903再次进入第二热风柜中，如此反复；同时冷凝器801及第二风机802启动，冷凝器801产生的冷却空气在第二风机802的吹送作用下进入第二冷风柜，再通过冷风通道613进入第一冷风柜611，经第三导管906进入第一热风柜608，经第一导管904导入蓄热水箱901，余热空气通过冷却管的902的末端连通三通阀907，调节三通阀907余热空气经第二导管905再次进入第一热风柜608，如此循环往复；
升温喷涂作业模式下：与升温喷涂作业模式不同的是，第一冷风柜611所产生的余热空气经过冷却管902的末端连通三通阀907，调节三通阀907在第四风机908的吹送作用下通过热风风道进入烤漆房的主体框架120中，为喷涂作业提供升温空气；
烘烤模式下：除尘组件及主要风循环系统停止工作，第一冷风柜611所产生的余热空气经过第三导管906，在第三风机609的吹送作用下，吹向第一输送带对分子筛进行余热，通过第一热风柜608后的预热空气经第一导管904导入蓄热水箱901，余热空气通过冷却管的902的末端连通三通阀907，调节三通阀907在第四风机908的吹送作用下通过热风风道进入烤漆房的主体框架120中，对主体框架120中的空气持续加热，在电控系统的控制作用下，温度可以根据需要调节到喷涂作业所需要的温度。
实施例四
本实施例为具有实施例一或实施例二中VOC废气处理净化装置的烤漆房的实施例，本实施例与实施例三相同，所不同之处在于，多个烤漆房同时工作，多个烤漆房的排布方式包括但不限于串联或并联的连接方式，如图9、图10所示。具体地，多个烤漆房共用一套分子筛净化组件300及分子筛循环组件，每个烤漆房设置有自己独立的进风组件100、第一导向组件400、除尘组件200和第二导 向组件500，多个烤漆房的循环风组件可共用一个。但需要说明的是，在采用多个烤漆房共用循环风组件时，将导风管道306设置多条支路，多条支路与各烤漆房一一对应。为实现多个烤漆房既可以独立工作、又可以两个或两个以上的烤漆房同时工作，本实施例可在每组进风组件100、每组循环风组件或循环风组件的导风管道306支路设置电磁控制阀。
实施例五
图6至图7所示为本发明VOC废气处理净化装置的第四实施例，本实施例与实施例一相同，所不同之处在于，输送组件包括第五输送带615、斗提616及第六输送带617，第五输送带615的一端设于收集器下方，第五输送带615的另一端设有将分子筛导向斗提616一端的导料斜口，斗提616另一端将分子筛导向第六输送带617的一端，第六输送带617的另一端位于分子筛净化组件的上方；加热组件为设于第五输送带615下方的发热管集合箱703，冷凝组件为位于分子筛净化组件旁侧且正对着第六输送带617的制冷空调803。如此，吸附有VOC的分子筛下落入收集器，并由收集器落入至第五输送带615，第五输送带615将分子筛向前输送的同时，发热管集合箱703升温对第五输送带615上的分子筛进行脱附处理，VOC气体在高温下直接分解为无害物质；脱附后的分子筛通过斗提616提升至第六输送带617，第六输送带617在输送分子筛的同时，制冷空调803对分子筛进行冷却，冷却的分子筛再次具备吸附功能；分子筛如此往复循环达到吸附、脱附、VOC高温分解的效果。
为了控制由收集器落入第五输送带615的分子筛数目，本实施例的收集器为变频给料器，在变频给料器的控制下限量定量向第五输送带615供应分子筛。
发热管集合箱703内排布有多个发热管，对第五输送带615上输送的分子筛进行升温，当温度升高至400℃时可对第五输送带615上的分子筛进行脱附处理，同时VOC气体在400℃的高温下分解为无害物质；为了防止加热过程中的大量热量散失，本实施例的发热管集合箱703及第五输送带615的壳体用隔热棉材料做包裹处理以防止热量散失。
导料斜口的设置是为了将第五输送带615上的分子筛导流至斗提616底部的同时组织热量的大量散失而做出的优选，并不作为本发明的限制性规定。
本实施例的斗提616包括传动带及多组均布于传送带表面的提板618，提板618从提斗通道的底部提起分子筛，提板618跟随传送带的旋转上升直至分子筛 落入第六输送带617上。
实施例六
本实施例与实施例五相同，所不同之处在于，本实施例的VOC废气处理净化装置还包括热交换组件810，热交换组件810包括第一热风风机811、空气混合室812、第二热风风机813、第三热风风机814、调控空调815及导向管道816，第一热风风机811连通输送组件所处空间与空气混合室812，第二热风风机813连通输送组件所处空间与调控空调815的内机进气道，调控空调815向空气混合室812输送冷却空气，第三热风风机814抽排空气混合室812内空气通过导向管道816排出，如图8所示。
本实施例在实施时，热量由发热管集合箱703产生，通过分子筛颗粒将部分热量带至斗提通道以及顶部第六输送带617所处通道中；冷空气由调控空调815产生，调控空调815的内机进风来源于第二热风风机813从输送组件所处空间内空气，经过调控空调815的冷却作用向空气混合室812输送冷却空气；第一热风风机811抽取输送组件所处空间内余热空气进入空气混合室812；冷却空气和余热空气在空气混合室812内混合，到达可控制的温度后通过第三热风风机814的抽排作用经导向管道816排至烤漆房或喷涂间。本实施例的热交换系统完全为内循环，不和外界气体产生交互，就达到了吸附、脱附、VOC高温分解的效果。
在分子筛冷凝过程中必然会产生液态水或水蒸气，本实施例设置多处排水管道将水排至容器收集。具体地，制冷空调803自带有第一排水管道，空气混合室812的底部设有第二排水管道、调控空调815自带的第三排水管道，斗提通道侧管壁安装的集水沟槽，第一排水管道、第二排水管道、第三排水管道及集水沟槽出水均通过水管排到容器中收集。脱水、排水可以使得硅含量较低的中孔分子筛在内封闭循环的条件下吸附水蒸汽、脱排水分使得内部小环境空气湿度降低，分子筛也具备吸附VOC的功能，这样大大降低了材料成本，同时喷涂间较低的湿度有助于提高水性漆的挥发、干燥效率。
为了实时监测VOC废气处理净化装置内各点温度，本实施例在第六输送带617通道设置有第一温度传感器、在第一热风风机811的入口设置有第二温度传感器、在第二热风风机813的入口设置有第三温度传感器、在第五输送带615通道设置有第四温度传感器、在发热管集合箱703内设置有第五温度传感器、在空气混合室812内设置有第六温度传感器、在收集器内设置有第七温度传感器、在 第二导向组件设置有第八温度传感器。当然，需要说明的是，温度传感器的设置位置并不限于上述位置，可根据实际应用需求设置温度监测点。各个温度传感器监测得数据可上传至PLC控制器，PLC控制器根据各个温度传感器监测的温度数据控制相应的电器元件工作或关停以达到自动控制的目的；本实施例的PLC控制系统还可连接故障报警系统，在某个电器元件出现故障的时候系统会自动报警，提醒工作人员对设备进行修理或者维护。
实施例七
本实施例为实施例四或实施例五中VOC废气处理净化装置的烤漆房的实施例，本实施例的烤漆房至少具备两种工作模式：
喷漆模式：通过进风组件100抽排进风，将废气抽排进入VOC废气处理净化装置；废气在第一导向组件400的作用下导向至除尘组件200去除废气中的颗粒物，随后废气在的第二导向组件500的作用下导向至分子筛净化组件300进行净化处理输出净化空气；净化后得空气通过风循环组件得作用重新进入喷涂间，吸附有VOC的分子筛301经加热脱附、冷凝处理后由输送组件600回送至分子筛循环组件中复用。
烘烤模式：调控空调815的冷却作用向空气混合室812输送冷却空气；第一热风风机811抽取输送组件所处空间内余热空气进入空气混合室812；冷却空气和余热空气在空气混合室812内混合，到达可以控制的温度后在经过第三热风风机814的抽排作用经导向管道816排至烤漆房或喷涂间对喷涂工件进行升温烘烤模式，加快喷涂工件的干固速度。
实施例八
本实施例为具有实施例六或实施例七中VOC废气处理净化装置的烤漆房的实施例，本实施例与实施例七相同，所不同之处在于，多个烤漆房同时工作，多个烤漆房的排布方式包括但不限于串联或并联的连接方式，如图9、图10所示。具体地，多个烤漆房共用一套分子筛净化组件300及分子筛循环组件，每个烤漆房设置有自己独立的进风组件100、第一导向组件400、除尘组件200和第二导向组件500，多个烤漆房的循环风组件可共用一个。但需要说明的是，在采用多个烤漆房共用循环风组件时，将导风管道306设置多条支路，多条支路与各烤漆房一一对应。为实现多个烤漆房既可以独立工作、又可以两个或两个以上的烤漆房同时工作，本实施例可在每组进风组件100、每组循环风组件或循环风组件的 导风管道306支路设置电磁控制阀。显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
