技术领域technical field
本实用新型涉及复合式除尘器领域,具体地说,涉及一种可适应不同工况的新型复合式除尘器。The utility model relates to the field of compound dust collectors, in particular to a novel compound type dust collector which can adapt to different working conditions.
背景技术Background technique
工业废气对大气的污染不容忽视。工业废气中含有的细颗粒物是造成雾霾等大气污染问题的重要来源之一。因此,工业除尘技术的研究与改进对治理大气污染十分重要。The air pollution caused by industrial waste gas cannot be ignored. The fine particulate matter contained in industrial waste gas is one of the important sources of air pollution problems such as smog. Therefore, the research and improvement of industrial dust removal technology is very important to control air pollution.
目前工业除尘最常用的设备有布袋除尘器、滤筒除尘器、旋风分离器等。其中布袋除尘器使用最为广泛,其除尘效率高,可以达到99%以上,可以过滤5微米以下的微小颗粒。但是,为提高滤袋除尘效率和使用寿命、降低能耗,一般来说进入布袋除尘器的气流速度和颗粒粒径都不宜过大,如强度相对较高的玻璃纤维袋式除尘器的过滤风速约为0.5~0.8m/s,处理颗粒粒径通常在5微米以下。并且高温、高湿环境对滤袋的过滤效率和使用寿命都有很大的不利影响。滤筒除尘器特征与布袋除尘器类似。旋风分离器相对于布袋除尘器或滤筒除尘器过滤效率稍低一些,通常处理15微米以上的颗粒物,效率约为80%~85%。但是,其对气流条件要求不高,可以处理高温、高湿等特殊气流。At present, the most commonly used equipment for industrial dust removal are bag filter, filter cartridge filter, cyclone and so on. Among them, the bag filter is the most widely used, and its dust removal efficiency is high, which can reach more than 99%, and can filter tiny particles below 5 microns. However, in order to improve the dust removal efficiency and service life of the filter bag and reduce energy consumption, generally speaking, the air velocity and particle size entering the bag filter should not be too large. It is about 0.5-0.8m/s, and the particle size of the treated particles is usually below 5 microns. And the high temperature and high humidity environment have great adverse effects on the filtration efficiency and service life of the filter bag. Cartridge filter features are similar to bag filter. Compared with bag filter or cartridge filter, the filtration efficiency of cyclone separator is slightly lower, and it usually deals with particles above 15 microns, and the efficiency is about 80% to 85%. However, it does not require high airflow conditions, and can handle special airflows such as high temperature and high humidity.
当前,为弥补各类除尘装置的短板,一些工业除尘系统采用多级过滤。以旋风分离器和袋式除尘器为例:含尘气流经由排气罩捕捉后会进入旋风分离器,大部分颗粒物,尤其是粒径较大的颗粒会因重力等作用沉降下来;之后较小的颗粒的随气流进入袋式除尘器被布袋过滤,最后洁净气流经排气管道排出。At present, in order to make up for the shortcomings of various dust removal devices, some industrial dust removal systems use multi-stage filtration. Take the cyclone separator and bag filter as examples: the dust-laden airflow will enter the cyclone separator after being captured by the exhaust hood, and most of the particles, especially those with larger particle size, will settle down due to gravity and other effects; The particles enter the bag filter with the airflow and are filtered by the bag filter, and finally the clean airflow is discharged through the exhaust pipe.
但是,多级过滤一般占地面积较大,管道较为复杂,适应工作环境的能力较差且能耗较高,设计、维护成本较高。However, multi-stage filtration generally occupies a large area, the pipeline is more complicated, the ability to adapt to the working environment is poor, the energy consumption is high, and the design and maintenance costs are high.

具体实施方式Detailed ways
为进一步了解本实用新型的技术方案,下面结合附图和实施例,对本实用新型作详细描述。In order to further understand the technical solution of the present utility model, the present utility model is described in detail below with reference to the accompanying drawings and embodiments.
如图1所示,本实用新型实施例提供了一种新型复合式除尘器,包括旋风分离器1、高效除尘室2和隔板3,旋风分离器1设置在高效除尘室2外壁周围,隔板3位于高效除尘室2上部,隔板3上设有孔洞,隔板3将高效除尘室2分割为上净气子室4和下除尘子室;所述高效除尘室2的滤芯5连接在隔板3的孔洞上,所述滤芯5位于下除尘子室,所述旋风分离器1与高效除尘室2的下除尘子室壁面滑动连接,所述旋风分离器1的气流出口与高效除尘室2的烟气进口连接。图1只是列出主要部件,连接部件、阀门等未在图中示意。优选的,所述滤芯5为袋式除尘器或滤筒除尘器。当然,滤芯5还可以为其他结构形式。上净气子室4设有净气出口7。净气出口7供洁净后的空气从高效除尘室2流出。As shown in FIG. 1 , the embodiment of the present utility model provides a new type of composite dust collector, which includes a

该实施例的复合式除尘器,经过旋风分离器1第一级过滤,再经过滤芯5第二级过滤,实现了气体的净化。通过设置两级过滤,使得气体净化更为彻底。该实施例的复合式除尘器,结构紧凑,可以置于厂房内部实现空气净化。The composite dust collector of this embodiment is filtered through the first stage of the
另外,本实施例中,布袋除尘器(或滤筒除尘器)数量、旋风分离器数量及排列方式不仅限于本实施例所列出的方式。所述旋风分离器1的进气入口均为含尘气体进口。本实施例中,所述滤芯5的数量、旋风分离器1的数量及排列方式均由具体工况和装置环境条件决定。本优选例例举出两种旋风分离器1排列方式:如图2所示,旋风分离器1布置在高效除尘室2两相对侧面;如图3所示,旋风分离器1布置在高效除尘室2四周侧面。通过合理设置旋风分离器1,可以实现对厂房内空气的净化。如果厂房一侧启动生产线,那么可以在启动与该侧对应的旋风分离器1。如果厂房所有生产线都启动,那么可以在启动所有旋风分离器1。In addition, in this embodiment, the number of bag filter (or filter cartridge filter), the number and arrangement of cyclone separators are not limited to those listed in this embodiment. The air inlets of the
采用上述结构,将两级过滤装置集成到一个装置中,通过设置共用灰斗,大大减少了装置的空间体积。By adopting the above structure, the two-stage filtering device is integrated into one device, and the space volume of the device is greatly reduced by arranging a common ash hopper.

上述优选例中,含尘气体自含尘气体进口进入旋风分离器1,先经过旋风分离器1的除尘过程,大于15微米的颗粒物被分离进入灰斗6,进而被去除大部分粉尘的气流进入高效除尘室2,经过滤芯5的除尘作用后,小于15微米的颗粒物被捕捉,洁净气流进入上净气子室4,进而由净气出口7排出。In the above preferred example, the dust-laden gas enters the
优选的,所述的复合式除尘器,还包括脉冲喷吹清灰装置,所述脉冲喷吹清灰装置位于上净气子室4,所述脉冲喷吹清灰装置位于隔板3上方。优选的,所述脉冲喷吹清灰装置包括气包8、电磁脉冲阀9和喷吹管10,喷吹管10出气口和滤芯5袋口相对,电磁脉冲阀9位于喷吹管10中。Preferably, the composite dust collector further includes a pulse jet cleaning device, the pulse jet cleaning device is located in the upper clean air sub-chamber 4 , and the pulse jet dust cleaning device is located above the partition plate 3 . Preferably, the pulse jet cleaning device includes an air bag 8 , an electromagnetic pulse valve 9 and a
所述高效除尘室2内,滤芯5中的滤袋(或滤筒)采用压缩空气进行脉冲喷吹清灰。当需要对滤芯5进行清灰处理时,启动电磁脉冲阀9,气包8中的气体以脉冲形式,喷出喷吹管10。由于喷吹管10出气口和滤芯5袋口相对,喷出的气体对滤芯5的袋体形成脉冲,且方向从滤芯5内侧流向滤芯5外侧。这实现了对滤芯5的清灰处理。从滤芯5脱离的灰尘落入下方的灰斗中。In the high-efficiency dust removal chamber 2, the filter bag (or filter cartridge) in the filter element 5 uses compressed air for pulse jet cleaning. When the filter element 5 needs to be cleaned, the electromagnetic pulse valve 9 is activated, and the gas in the air bag 8 is sprayed out of the blowing
优选的,高效除尘室2的滤芯5与隔板3孔洞为螺纹连接。螺纹连接是一种可拆卸的固定连接,具有结构简单、连接可靠、装拆方便等优点。因此可以实现袋式除尘器或者滤筒除尘器自身或者相互间的快换。Preferably, the filter element 5 of the high-efficiency dust removal chamber 2 is connected with the holes of the partition plate 3 by screw threads. Threaded connection is a detachable fixed connection, which has the advantages of simple structure, reliable connection, and convenient assembly and disassembly. Therefore, the bag filter or the filter cartridge filter can be quickly exchanged by itself or with each other.
优选的,所述的复合式除尘器还包括自动调节阀,所述自动调节阀设置在旋风分离器1的烟气进口处。视工况要求调节自动调节阀开度,改变进口分量及风速。当然,也可以视风量要求,决定使用或关闭旋风分离器的数量。Preferably, the compound dust collector further includes an automatic adjustment valve, and the automatic adjustment valve is arranged at the flue gas inlet of the
作为优选例,所述的复合式除尘器还包括提升阀,所述提升阀设置在隔板3孔洞气道上方。所述孔洞气道上设置有可以控制所述高效除尘室与净风室连通或切断状态的提升阀。As a preferred example, the compound dust collector further includes a lift valve, and the lift valve is arranged above the air passage of the 3 holes in the partition plate. The hole air passage is provided with a poppet valve that can control the communication or cut-off state between the high-efficiency dust chamber and the clean air chamber.
由于工业产业的不同,产生的烟气种类也不同。但是滤芯5对烟气要求较高,如温度、湿度不能太高,风量不能太大等。但是旋风分离器1则具有耐高温、耐磨损的特点。因此,含尘气体首先进入旋风分离器1可以不仅较好地满足不同工况的要求,而且可以降低含尘气流流速及气流温度,分离较大粒径颗粒,减小滤芯5的工作负荷,满足滤芯5的工作要求。同时,旋风分离器只能去除大于15微米的大颗粒,且效率较低,但是滤芯可以去除小于15微米的微细颗粒,且除尘效率很高,因此将滤芯5依次布设在旋风分离器1的后面,可以优势互补。Due to different industrial industries, the types of flue gas produced are also different. However, the filter element 5 has higher requirements on the flue gas, such as the temperature and humidity should not be too high, and the air volume should not be too large. However, the
上述实施例的除尘器中,高效除尘室2内滤芯5可替换,可以满足不同的除尘要求;旋风分离器1的位置可变,可以满足不同的工作环境及工况要求;共用灰斗,可以节约空间且方便清理。In the dust collector of the above embodiment, the filter element 5 in the high-efficiency dust removal chamber 2 can be replaced, which can meet different dust removal requirements; the position of the
