Description
技术领域technical field
本实用新型属于大气环境治理技术装备及方法领域，更具体地，涉及一种集成除尘器装置。The utility model belongs to the field of atmospheric environment treatment technical equipment and methods, and more specifically relates to an integrated dust collector device.
背景技术Background technique
除尘是大气污染治理中最重要的手段之一。干式除尘是工程上最主要的形式，通常的干式除尘方法有旋风除尘、过滤除尘和布袋除尘等。旋风除尘设备投资小，风阻小，但是，对细小的质点的去除效果差。过滤除尘成本也较低，但是风阻较大，对细小的质点的除尘效果也较差，填料容易堵塞，多用于高温除尘。布袋除尘能够去除细小的质点，除尘效率高，是目前最可靠的除尘方法，但是设备投资大，频繁需要反吹清除堵塞层。在工程上，为了减少除尘系统的投资，也常常将旋风除尘和布袋除尘联用。Dust removal is one of the most important means in air pollution control. Dry dust removal is the most important form in engineering. Common dry dust removal methods include cyclone dust removal, filter dust removal and bag dust removal. The investment of cyclone dust removal equipment is small, and the wind resistance is small, but the removal effect on fine particles is poor. The cost of filter dust removal is also low, but the wind resistance is relatively large, and the dust removal effect on fine particles is also poor, and the filler is easy to block, so it is mostly used for high temperature dust removal. Bag dust removal can remove fine particles and has high dust removal efficiency. It is the most reliable dust removal method at present, but the investment in equipment is large, and back blowing is frequently required to remove the clogged layer. In engineering, in order to reduce the investment of the dust removal system, cyclone dust removal and bag dust removal are often used together.
尽管现有技术中已有将旋风除尘和布袋除尘联用的情况，但通常的联用方式存在风阻大，占地大，设备投资大的问题。现有的联用除尘器，每一级除尘器均各有一套进气口和出气口，每一种除尘器的进口和出口都需要通过一个大的集气再收口，在各种除尘器联用的方法中，人们常常是机械地把各个除尘器分别制造，再用管道连接。采用这样的方式，在前一级除尘器的出口和下一级的进口组合起来的中间，多了很多的多虑的空间和管路，既造成材料的浪费、空间的占用，又会增大风阻(尤其是对于使用弯道的情况)；而将前一级除尘器的出口和下一级的进口集成为一个、去除连接管时，又存在前一级除尘器的粉尘排除的困难；如果没有特殊结构的话，中间分离出的粉尘又会进入下一级除尘器，造成下一级除尘器的堵塞，影响除尘器的正常工作。另外，现有的联用方式，更多的需要依赖于布袋除尘工段，造成布袋除尘过大的负荷，由于布袋除尘造价高，频繁的反吹，容易造成对电器件和控制系统稳定性的高度依赖，在没有专业的技术维护人员的情况下，容易造成布袋除尘器停摆。Although the combined use of cyclone dust removal and bag dust removal has been used in the prior art, the common way of combined use has the problems of large wind resistance, large land occupation, and large equipment investment. In the existing combined dust collector, each stage of dust collector has a set of air inlet and outlet, and the inlet and outlet of each dust collector need to pass through a large gas collection port. In the current method, people often mechanically manufacture each dust collector separately, and then connect them with pipes. In this way, in the middle of the combination of the outlet of the previous stage dust collector and the inlet of the next stage, there is a lot of space and pipelines for worrying, which not only causes waste of materials, occupation of space, but also increases Wind resistance (especially for the use of bends); and when the outlet of the previous stage dust collector and the inlet of the next stage are integrated into one, and the connecting pipe is removed, there is also the difficulty of dust removal from the previous stage dust collector; if If there is no special structure, the dust separated in the middle will enter the next-stage dust collector, causing blockage of the next-stage dust collector and affecting the normal operation of the dust collector. In addition, the existing combination method needs to rely more on the bag dust removal section, resulting in an excessive load of bag dust removal. Due to the high cost of bag dust removal and frequent back blowing, it is easy to cause a high degree of stability to electrical devices and control systems. Reliance, in the absence of professional technical maintenance personnel, it is easy to cause the bag filter to stop.

通过本实用新型所构思的以上技术方案，与现有技术相比，具有以下有益效果：Compared with the prior art, the above technical solution conceived by the utility model has the following beneficial effects:
1.本实用新型的集成除尘器装置是将旋风除尘、填料过滤除尘和布袋除尘三种方法顺次集成在一个整体的除尘器中，并分别按下、中、上的方式排布，能够进一步减少布袋除尘投资和运行成本。由于在布袋除尘前增加了旋风除尘装置(即旋风除尘器)和填料过滤除尘装置(即填料过滤除尘器)两级除尘，并将它们三者在空间上布置成下中上的立体布置，前一级除尘装置的出风口与后一级除尘装置的进风口合二为一，前后两级除尘器连接管路零风阻对接，节约设备造价和占地面积，特别适用于小型的除尘工况中。同时布袋不采用压缩空气反吹的方法，而采用及时更换堵塞的布袋的方法，以减少反吹的设备投资和反吹系统的故障所导致除尘系统运行的不可靠性。1. The integrated dust collector device of the present utility model integrates the three methods of cyclone dust removal, filler filter dust removal and cloth bag dust removal in sequence into an integral dust collector, and arranges them in the way of pressing down, middle and up respectively, which can further Reduce bag dust removal investment and operating costs. Because the two-stage dust removal of the cyclone dust removal device (that is, the cyclone dust collector) and the packing filter dust removal device (that is, the packing filter dust collector) is added before the bag dust removal, and the three of them are arranged in a three-dimensional arrangement of the lower, middle and upper in space, the front The air outlet of the first-stage dust removal device and the air inlet of the second-stage dust removal device are combined into one, and the connecting pipelines of the front and rear two-stage dust collectors are connected with zero wind resistance, which saves equipment cost and floor space, and is especially suitable for small dust removal conditions. . At the same time, the cloth bag does not use the method of compressed air back blowing, but the method of replacing the blocked bag in time, so as to reduce the equipment investment of back blowing and the unreliability of the operation of the dust removal system caused by the failure of the back blowing system.
2.本实用新型将旋风、过滤和布袋除尘三种工艺集成于一体的除尘器装置，该装置与该装置对应的除尘方法是依据气流上浮的流体力学原理，即含尘气流(即待除尘的气流)首先经过旋风除尘单元，大粉尘质点首先在离心力的作用下沉积在旋风除尘单元，实现初级除尘；轻质的小粉尘质点上浮，直接进入近位于上方的填料过滤除尘单元，大部分粉尘质点被拦截在填料过滤除尘单元；更为细小的粉尘质点继续上浮，直接进入近位于更高上方的布袋除尘单元，并被布袋拦截。将这三种工艺集成于一体的除尘器系统所形成的高位通道，同高烟囱一样，使气流有一定的自吸上浮能力，减少了风阻。同时，一部分粉尘质点本身因上行的重力阻力而沉积在下方的除尘单元中。2. The utility model integrates the three processes of cyclone, filtration and bag dust removal into one dust collector device. The device and the dust removal method corresponding to the device are based on the principle of fluid mechanics of air flow upwards, that is, the dust-laden air flow (that is, the dust to be removed) The air flow) first passes through the cyclone dust removal unit, and the large dust particles are first deposited in the cyclone dust removal unit under the action of centrifugal force to achieve primary dust removal; the light and small dust particles float up and directly enter the packing filter dust removal unit near the top, most of the dust particles It is intercepted in the packing filter dust removal unit; the finer dust particles continue to float up, directly enter the bag dust removal unit near the higher top, and are intercepted by the bag. The high-level channel formed by the dust collector system integrating these three processes, like the high chimney, enables the air flow to have a certain self-absorption and floating ability, reducing wind resistance. At the same time, part of the dust particles themselves are deposited in the dust removal unit below due to the upward gravitational resistance.
3.本实用新型还在容易堵塞的填料过滤除尘器(尤其是填料支撑孔板)上设置有震动机构，可以定期或不定期的震动填料支撑孔板，使填料支撑孔板上附着的(甚至是填料缝隙间的)灰尘抖落至积尘室；同时通过过滤除尘出灰口对积尘室抽风，可以排出堵塞在填料支撑孔板上甚至是填料缝隙间的粉尘，实现填料除尘机构内部的堵塞清理。3. The utility model is also equipped with a vibrating mechanism on the packing filter and dust collector (especially the packing support orifice plate) that is easy to be blocked, which can periodically or irregularly vibrate the packing support orifice plate, so that the packing support orifice plate is attached (even The dust from the gap between the fillers shakes off to the dust accumulation chamber; at the same time, the dust accumulation chamber is ventilated through the dust removal outlet of the filter, which can discharge the dust blocked on the filler support orifice or even the gap between the fillers, so as to realize the dust removal mechanism inside the filler Blockage clearing.
本实用新型通过将三种常用除尘方法进行集成，三种除尘器之间采用无风阻的直接对接，气流顺次上浮等方法，克服常规除尘器联用风阻大、占地大等的缺点。待除尘的含尘气体首先通过旋风除尘器去除气体中的大的粉尘颗粒，然后通过填料过滤除尘器去除气体中细小的粉尘，最后再通过布袋除尘器去除气体中更细小的粉尘。另外，由于布袋除尘器前级分别设置有旋风除尘、填料过滤除尘，能够减小布袋除尘器的负荷，降低反吹频率，减少反吹过程中压缩空气的能耗，提高其工作稳定性，延长布袋除尘器的使用寿命。The utility model integrates three commonly used dust removal methods, adopts direct docking without wind resistance between the three dust collectors, and adopts methods such as airflow sequentially floating up, etc., to overcome the shortcomings of conventional dust collectors, such as large wind resistance and large footprint. The dust-laden gas to be dedusted first passes through the cyclone dust collector to remove large dust particles in the gas, then passes through the filler filter dust collector to remove fine dust in the gas, and finally passes through the bag filter to remove finer dust in the gas. In addition, because the front stage of the bag filter is equipped with cyclone dust removal and packing filter dust removal, it can reduce the load of the bag filter, reduce the frequency of back blowing, reduce the energy consumption of compressed air during the back blowing process, improve its working stability, and prolong the life of the bag filter. The service life of the bag filter.
另一方面，本实用新型在传质上采取了措施，通过合理的中间过度的存灰和沉积的方法，过度段的粉尘及时沉积排除。例如在布袋除尘器下方合理设计的存灰板及其小管束，既可以保证填料过滤除尘与布袋除尘间的无风阻通道，又能保证从布袋除尘器上分离出来的粉尘不再返回到填料过滤除尘器的滤床上。旋风除尘器、填料过滤除尘器和布袋除尘器中收集的粉尘颗粒在不影响集成除尘装置工作的情况下可以及时处理(通过出灰口等)，便于设备维护。例如，布袋孔板与布袋除尘存灰板之间形成的空间可用于收集除尘布袋中的灰尘，通气管束和布袋除尘出灰口也位于布袋孔板与布袋除尘存灰板之间，通气管束是填料过滤除尘器和布袋除尘器之间的气流通道(即气体通过通气管束来到布袋的入气口，随后进入除尘布袋)，通气管束的位置避开布袋口的正下方，以免布袋除尘器中的粉尘又落回到填料过滤除尘。通气管束的高度(即通气管束的出气口位置)高于存灰板一定的距离，通过及时除灰控制存灰板上沉积粉尘厚度，就可以避免通气管束出气口的堵塞，并避免布袋除尘过滤的粉尘又返回到填料过滤除尘器中。On the other hand, the utility model has taken measures in mass transfer, through a reasonable intermediate excessive ash storage and deposition method, the dust in the excessive section is deposited and eliminated in time. For example, the dust storage plate and its small tube bundles are reasonably designed under the bag filter, which can not only ensure the air-free passage between the packing filter dust removal and the bag filter, but also ensure that the dust separated from the bag filter will not return to the packing filter. The filter bed of the dust collector. The dust particles collected in the cyclone dust collector, packing filter dust collector and bag filter can be processed in time (through the ash outlet, etc.) without affecting the work of the integrated dust removal device, which is convenient for equipment maintenance. For example, the space formed between the bag hole plate and the bag dust removal and ash storage plate can be used to collect the dust in the dust removal bag. The ventilation tube bundle and the bag dust removal ash outlet are also located between the bag hole plate and the bag dust removal and ash storage plate. The ventilation tube bundle is The air flow channel between the packing filter dust collector and the bag filter (that is, the gas comes to the air inlet of the bag through the ventilation tube bundle, and then enters the dust bag). The dust falls back to the filler to filter the dust. The height of the ventilation tube bundle (that is, the position of the air outlet of the ventilation tube bundle) is higher than a certain distance from the ash storage plate. By timely ash removal to control the thickness of the deposited dust on the ash storage plate, it is possible to avoid the blockage of the ventilation tube bundle outlet and avoid bag dust removal and filtration. The dust is returned to the packing filter dust collector.

The bag replacement door is located on the bag cover and is used to open and close the bag cover. The other end of each cloth bag is closed, and the outer cover of the cloth bag is connected with the tank body of the filler filter dust collector by flange. The clogged bag does not use online dust cleaning (such as online back blowing to remove the clogged layer, etc.), but adopts the method of grouping and regularly replacing the bag (for example, open the bag replacement door, and remove the dust bag that needs to be replaced from the bag hanger) , and install the new dust removal bag on the bag hanger, and finally close the bag replacement door), remove the blocked bag and go offline to suck ash on a special mechanism and wash it with water for repeated use.
填料支撑孔板3上还设置有震动机构，用于振动该填料支撑孔板3，抖落填料支撑孔板3上积累的灰尘。落下的灰尘可积累在积尘室内，并最终通过过滤除尘出灰口4清理。A vibrating mechanism is also provided on the packing supporting orifice 3 for vibrating the packing supporting orifice 3 to shake off the dust accumulated on the packing supporting orifice 3 . Falling dust can be accumulated in the dust accumulation chamber, and finally clean up by filter dust removal ash outlet 4.
由于填料过滤除尘器2为过滤除尘，较易发生堵塞。因此，本实施例还在气流流经填料支撑孔板3的前方和后方(即填料层的下方和上方，填料支撑孔板3用于放置该填料层)至少分别设置1个气压监测器，用于监测气流的气压，从而判断填料层气流堵塞的情况。当前方的气压监测器读数与后方的气压监测器读数存在显著差异时，则表明填料过滤除尘器的填料支撑孔板或填料层发生堵塞，需要更换或清理。Since the filler filter dust remover 2 is for filtering dust, it is more likely to be blocked. Therefore, the present embodiment also arranges at least one air pressure monitor respectively in front and rear of the air flow through the packing support orifice plate 3 (i.e. below and above the packing layer, and the packing support orifice plate 3 is used to place the packing layer). It is used to monitor the air pressure of the air flow, so as to judge the air flow blockage of the packing layer. When there is a significant difference between the front air pressure monitor reading and the rear air pressure monitor reading, it indicates that the packing support orifice or packing layer of the packing filter dust collector is blocked and needs to be replaced or cleaned.
