本发明专利申请是针对申请号为：2015102993719的分案申请，原申请的申请日为：2015年06月03日，发明创造名称为：一种单风机粉尘吸收净化器及其吸收净化方法。The patent application of the present invention is a divisional application with application number: 2015102993719. The application date of the original application is: June 3, 2015. The name of the invention is: a single-fan dust absorption purifier and its absorption and purification method.
技术领域technical field
本发明属于工业除尘净化技术领域，更具体地说，涉及一种单风机粉尘吸收净化器的吸收净化方法。The invention belongs to the technical field of industrial dust removal and purification, and more specifically relates to an absorption and purification method of a single fan dust absorption and purification device.
背景技术Background technique
在采矿业、石料破碎业、制粉行业、发电行业、冶炼行业、化工行业、机械制造行业都会产生大量的粉尘，严重污染空气，降低了生活的质量，破坏了生态环境，同时工人在此环境下工作，很可能导致呼吸道狭隘、肺活量减少或呼吸困难，长期下去可引起尘肺病，对人造成近期和远期的危害，所以必须对粉尘予以控制，不让其污染环境、危害人体健康。In the mining industry, stone crushing industry, milling industry, power generation industry, smelting industry, chemical industry, and machinery manufacturing industry, a large amount of dust will be generated, which will seriously pollute the air, reduce the quality of life, and destroy the ecological environment. Working under the environment is likely to lead to narrow airway, reduced lung capacity, or difficulty in breathing. It can cause pneumoconiosis in the long run and cause short-term and long-term harm to people. Therefore, dust must be controlled to prevent it from polluting the environment and endangering human health.
现有的粉尘净化器一般都是采用气路迂回的方式，从而达到净化的目的，但是这种方法会导致气体的阻力较大，也会导致引风机的功率加大，从而能耗也加大，另外，现有的技术中还采用了用过滤罩和过滤尘袋的方法进行过滤，这种方法的缺陷在于须定期清理过滤罩和吸尘罩，使用起来很不方便，使用寿命较短，需要经常更换，维护不便，而且过滤袋的过滤面积有限，如果需要达到一定的过滤面积，粉尘回收净化器设备体积要增大，生产成本费用较高，最重要的是无法彻底解决净化微尘的问题。Existing dust purifiers generally adopt a circuitous air path to achieve the purpose of purification, but this method will lead to greater resistance of the gas, and will also increase the power of the induced draft fan, thereby increasing energy consumption , In addition, the existing technology also adopts the method of filtering with a filter cover and a filter dust bag. The defect of this method is that the filter cover and the dust collection cover must be cleaned regularly, which is very inconvenient to use and has a short service life. It needs to be replaced frequently, maintenance is inconvenient, and the filter area of the filter bag is limited. If a certain filter area needs to be reached, the volume of the dust recovery purifier will increase, the production cost will be higher, and the most important thing is that it cannot completely solve the problem of purifying fine dust. question.
发明人曾就焊烟的吸收净化做过申请，申请号201310371403.2，申请日为2013年8月23日，发明名称为：一种单风机焊烟吸收净化器，该申请案包括吸烟机构、焊烟净化机构和焊烟跟踪机构，所述的吸烟机构包括风机，该风机将焊接烟尘吸收并输送至焊烟净化机构，所述的焊烟净化机构包括净化室和反冲器，该反冲器位于净化室内部，且该反冲器的底部与净化室相连通，净化室内部装有净化液，上述的风机将焊接烟尘输送至反冲器内部的净化液中，所述的焊烟跟踪机构作用于吸烟机构，用于控制吸烟机构以焊接速度跟踪吸收焊接烟尘。该申请案利用反冲器解决了如何使焊烟轻易的进入并停留在净化室内的净化液中，然后通过反冲器对净化液的作用使得旱烟被吸收净化，从而提高焊烟吸收净化的效率，但是如果将焊烟吸收净化器用于对粉尘的吸收净化，其不足之处就显而易见了，焊烟的颗粒较小，焊烟吸收净化器解决的是如何使其进入净化液中，对于粉尘这种大颗粒而言，要解决的问题不仅仅是如何进入净化液中，其技术难点是如何保证其在雾化净化液中的净化效果，并且由于粉尘颗粒较大较重，需要较大功率的风机才能保证吸收效果，但是较大功率的风机又使得粉尘在接触雾化净化液后又迅速离开，导致接触时间过短不能保证吸收效果，尤其是浓度较大的粉尘气体接触面积不够更一步降低吸收效率，而且出气管上端的过滤器、钢丝球和海绵块等均需要经常进行更换，无形之中增加净化成本。The inventor once applied for the absorption and purification of welding fume, the application number is 201310371403.2, and the application date is August 23, 2013. The name of the invention is: a single-fan welding fume absorption and purification device. The application includes smoking mechanism, welding fume Purification mechanism and welding smoke tracking mechanism, the smoking mechanism includes a fan, the fan absorbs the welding fume and transports it to the welding fume purification mechanism, and the welding fume purification mechanism includes a clean room and a recoiler, the recoiler is located at The inside of the clean room, and the bottom of the recoiler is connected with the clean room, the inside of the clean room is equipped with a purification liquid, the above-mentioned fan transports the welding fume to the purification liquid inside the recoiler, and the welding fume tracking mechanism functions For the smoking mechanism, it is used to control the smoking mechanism to track and absorb welding fume at the welding speed. This application uses the recoiler to solve how to make the welding fume easily enter and stay in the purification liquid in the clean room, and then through the action of the recoiler on the purification liquid, the dry smoke is absorbed and purified, thereby improving the efficiency of welding fume absorption and purification , but if the welding fume absorption purifier is used to absorb and purify dust, its shortcomings are obvious. The particles of welding fume are small. The solution of the welding fume absorption purifier is how to make it enter the purification liquid. For large particles, the problem to be solved is not only how to enter the purification solution, but the technical difficulty is how to ensure its purification effect in the atomized purification solution, and because the dust particles are larger and heavier, a larger power filter is required. The fan can ensure the absorption effect, but the larger power fan makes the dust leave quickly after contacting the atomized purification liquid, resulting in too short contact time to ensure the absorption effect, especially the contact area of the dust gas with a large concentration is not enough to further reduce The absorption efficiency is high, and the filter, steel ball and sponge block at the upper end of the outlet pipe need to be replaced frequently, which will increase the purification cost virtually.
