背景技术Background technique
传统生产纤维板线的干燥系统，采用的是旋风分离器，借助物料的离心力，而使物料从气流中分离出来，旋风分离器出口直接排空，一般旋风分离器分离效率为95％左右，由于排放的气流中含有大量的水蒸汽及部分粉尘，这样容易造成粉尘排放超标。随着人们对保护环境意识逐步提高，环境法对企业只会越来越严，高、中密度板的生产线是极易产生粉尘排放的行业，传统的一级除尘粉尘排放量已超标，很难达到排放的环保要求。The traditional drying system for the production of fiberboard lines uses a cyclone separator, which uses the centrifugal force of the material to separate the material from the air flow. The outlet of the cyclone separator is directly emptied. Generally, the separation efficiency of the cyclone separator is about 95%. Due to the discharge The air flow in the air contains a large amount of water vapor and some dust, which will easily cause the dust emission to exceed the standard. With the gradual improvement of people's awareness of environmental protection, environmental laws will only become more stringent for enterprises. The production line of high-density and medium-density boards is an industry that is prone to dust emissions. The dust emissions of traditional primary dust removal have exceeded the standard, and it is difficult To meet the environmental protection requirements of emissions.

具体实施方式Detailed ways
下面结合具体实施例对本实用新型做进一步的说明。Below in conjunction with specific embodiment the utility model is described further.
图1所示，一种生产纤维板的二级除尘装置，在一级除尘装置的基础上，增加二级除尘装置，一级除尘装置的出口与二级除尘装置的进口用焊管连接。所述一级除尘装置采用旋风分离器。所述的二级除尘装置采用旋风分离器。所述的生产纤维板的二级除尘装置还包括与二级除尘装置匹配使用的粉尘回收装置。所述的二级粉尘回收装置包括二级收集螺旋及二级废料仓，通过二级收集螺旋控制粉尘回收利用或打废。As shown in Figure 1, a secondary dedusting device for the production of fiberboard, on the basis of the primary dedusting device, a secondary dedusting device is added, and the outlet of the primary dedusting device is connected to the inlet of the secondary dedusting device with a welded pipe. The primary dust removal device adopts a cyclone separator. The secondary dust removal device adopts a cyclone separator. The secondary dust removal device for producing fiberboard also includes a dust recovery device matched with the secondary dust removal device. The secondary dust recovery device includes a secondary collection screw and a secondary waste bin, through which dust can be recycled or discarded.
含有粉尘的气流经过一级除尘旋风分离器1出口后往二级除尘旋风分离器输送，经过二级除尘旋风分离器2分离的粉尘进入二级收集螺旋3，收集螺旋正转时打入一级除尘旋风分离器1现有风选系统5，如粉尘需要打废二级收集螺旋3反转打入二级废料仓4。The dust-containing airflow passes through the outlet of the first-stage dust removal cyclone separator 1 and then is transported to the second-stage dust removal cyclone separator. The dust removal cyclone separator 1 has an existing winnowing system 5, and if the dust needs to be scrapped, the secondary collection screw 3 is reversely driven into the secondary waste bin 4.
相比原有一级除尘，增加本装置后达到更节能更环保低碳作用。具体除尘作用及流程说明：含有粉尘的气流经过一级除尘旋风分离器出口后往二级除尘旋风分离器输送，达到二级除尘的目的，经过二级除尘旋风分离器分离的粉尘，利用收集螺旋打入现有风选系统，纤维打废可由分料器及收集螺旋控制打入废料仓中。比如纤维板工厂生产线的日产量为550m3/天，每天实际消耗的绝干纤维量约550*0.78(比重)/0.95(效率)＝450.5t，如果只有一级旋风分离器，则每天直接往外排放的粉尘量约为450.5*5％＝2.25t。本实用新型在原来的基础上增加二级除尘装置后，每天粉尘的实际排放量约为2.25*5％＝0.012t,理论和实际上大幅度减少了粉尘的排放。Compared with the original first-level dust removal, the addition of this device achieves more energy-saving, more environmentally friendly and low-carbon effects. Specific dust removal function and process description: the airflow containing dust passes through the outlet of the primary dust removal cyclone separator and then is transported to the secondary dust removal cyclone separator to achieve the purpose of secondary dust removal. The dust separated by the secondary dust removal cyclone separator is collected by the spiral Injected into the existing air separation system, the fiber waste can be controlled by the distributor and the collection screw into the waste bin. For example, the daily output of the fiberboard factory production line is 550m 3 /day, and the actual consumption of absolute dry fiber per day is about 550*0.78 (specific gravity)/0.95 (efficiency)=450.5t. If there is only one-stage cyclone separator, it will be discharged directly to the outside every day The amount of dust is about 450.5*5%=2.25t. After the utility model adds a secondary dedusting device on the original basis, the actual discharge of dust per day is about 2.25*5%=0.012t, which greatly reduces the discharge of dust in theory and in practice.
本实用新型不局限于以上所述的具体实施方式，以上所述仅为本实用新型的较佳实施例而已，并不用以限制本发明，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。The utility model is not limited to the specific implementation manners described above. The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the present invention. Any changes made within the spirit and principles of the utility model Modifications, equivalent replacements and improvements, etc., should all be included within the protection scope of the present utility model.
