8个要素帮你做好美高梅在线登录网址除尘设备的选型

文章发布: 发表时间: 2017-02-14 10:52:43

美高梅在线登录网址除尘设备的滤料即是合成纤维、天然纤维或玻璃纤维织成的布或毡。依据烟气性质,挑选出合适于运用条件的滤料。
Environmental protection dust removal equipment is a synthetic material, natural fiber or glass fiber woven cloth or felt. According to the characteristics of the flue gas, select the suitable conditions for the use of filter media.
“一般,在烟气温度低于120℃,要求滤料具有耐酸性和耐久性的状况下,常选用涤纶绒布和涤纶针刺毡;在处理高温烟气(<250℃)时,首先要选用石墨化玻璃丝布;在某些特殊状况下,选用炭素纤维滤料等。
"In general, the flue gas temperature is below 120 DEG C, filter medium for having acid resistance and durability of the situation, often used in polyester velvet and polyester felt; in the treatment of high temperature gas (<250 C), first choice of graphitization of glass fibre cloth; in some special conditions, using carbon fiber filter etc..
已然美高梅在线登录网址除尘设备对咱们日子这么主要,那么咱们该如何挑选哪款,或者说那种愈加合适自己的家庭,另外啥型号的美高梅在线登录网址除尘设备会对比好,又有哪些注意事项呢,下面就从八个便利简单先容下除尘器选型需求思考的要素:
Is environmental protection equipment so mainly on our day, so we should how to choose which one, or say that more suitable for their families, in addition to what types of environmental protection equipment would be better, and what precautions, following on from the eight elements of a convenient and simple introduction precipitator on demand:
1美高梅在线登录网址除尘设备运用温度
1 Application of environmental protection dust removal equipment
关于美高梅在线登录网址除尘设备来说,其运用温度取决于两个要素,第一是滤料的最高接受温度,第二是气体温度必须在露点温度以上。对美高梅在线登录网址除尘设备来说,运用温度与除尘功率联系并不显着,这一点不同于电除尘,对美高梅在线登录网址除尘设备来说,温度的改变会影响到粉尘的比电阻等影响除尘功率。
On the environmental protection dust removal equipment, the use of temperature depends on two elements, the first is the maximum acceptable temperature of the filter material, the second is the gas temperature must be above the dew point temperature. Of environmental protection equipment, the use of temperature and dust power relation is not significant, which is different from the electric dust, dust removal equipment for environmental protection, the change of temperature will affect the dust resistance effect of dust removing power.
2美高梅在线登录网址除尘设备进口处的含尘浓度
2 dust concentration at the inlet of environmental protection dust removal equipment
关于美高梅在线登录网址除尘设备来说,进口含尘浓度将直接影响下列要素:
With regard to environmental protection dust removal equipment, the concentration of imported dust will directly affect the following elements:
⑴压力丢失和清灰周期。进口浓度增大,同一过滤面积上积灰速度快,压力丢失随之添加,结果是不得不添加清灰次数。
The pressure loss and the cleaning cycle. With the increase of the inlet concentration, the ash content of the same filtration area is rapid, and the pressure loss increases.
⑵滤袋和箱体的磨损。在粉尘具有强磨蚀性的状况下,其磨损量能够以为与含尘浓度成正比。
The wear bag and box. With strong abrasive dust in the condition, the wear amount can be thought and is proportional to the concentration of dust.
⑶预收尘有无必要。预收尘即是在美高梅在线登录网址除尘设备进口处前再添加一级除尘设备,也称前级除尘。
The dust is necessary in advance. The advance is a dust removal equipment is added in environmental protection equipment imported before, also known as the dust before.
⑷排灰设备的排灰才能。排灰设备的排灰才能应以能排出悉数收下的粉尘为准,粉尘量等于进口含尘浓度乘以处理风量。
The ash can row ash equipment. Ash discharge equipment should be able to discharge the dust to accept all of the above, the amount of dust is equal to the concentration of imported dust by processing air.
⑸操作办法。美高梅在线登录网址除尘设备分为正压和负压两种操作办法,为削减风机磨损,进口浓度大的不宜选用正压操作办法
The methods of operation. Environmental protection dust removal equipment is divided into positive pressure and negative pressure two operation methods, in order to reduce the wear and tear of fans, the import of large concentration should not choose the positive pressure method
3出口含尘浓度
3 outlet dust concentration
出口含尘浓度指美高梅在线登录网址除尘设备的排放浓度,表示办法同进口含尘浓度,出口含尘浓度的大小应以本地美高梅在线登录网址请求或用户的请求为准,美高梅在线登录网址除尘设备的排放浓度一般都能到达50g/Nm3以下。
The outlet dust concentration refers to the emission of dust environmental protection equipment, said the way with the import of dust concentration, dust concentration of outlet size should be based on local environmental protection request or user request shall prevail, the emission concentration of dust environmental protection equipment generally can reach below 50g/Nm3.
4美高梅在线登录网址除尘设备处理风量
4 environmental dust removal equipment handling air volume
是美高梅在线登录网址除尘设备在单位时间内所能净化气体的体积量。单位为每小时立方米(m3/h)或每小时标立方米(Nm3/h)。是袋式除尘器规划中最主要的要素之一。依据风量规划或挑选袋式除尘器时,一般不能使除尘器在超越规则风量的状况下运转,不然,滤袋简单阻塞,寿数缩短,压力丢失大幅度上升,除尘功率也要下降;但也不能将风量选的过大,不然添加设备出资和占地面积。合理的挑选处理风量常常是依据技术状况和经验来决议的。
It is the volume of the purified gas in the unit time. Units per cubic meter (m3/h) or per hour standard cubic meter (Nm3/h). It is one of the most important factors in the planning of bag filter. On the basis of planning or the selection of air bag type dust collector, generally can not make the dust collector operation in air condition or beyond the rules, simple bag obstruction, life is shortened, the pressure loss increased, dust power should also decrease; but it cannot be selected volume is too large, not to add equipment investment and covers an area of. Reasonable selection of air handling is often based on technical conditions and experience to decide.
5压力丢失
5 pressure loss
假如缺少更恰当的规划经验,在过滤速度较低时能够把75×9.8帕作为典型数据。但若采纳较高的过滤速度,或存在粘性或低孔率的尘埃层,应取稍高的数值。
If there is a lack of a more appropriate planning experience, the 75 * 9.8 PA can be used as a typical data at low filtration rates. However, the higher the filtration rate, or the presence of viscous or low porosity dust layer, should take a slightly higher value.
6过滤速度即气布比。
6 the filtration rate of gas bubbe.
它是被过滤的气体流量(m3/min)同除尘布袋面积(m2)的比值,其因次为m3/min.m2=m/min。这是速度的单位,它代表气体经过除尘布袋的平均速度,不思考有很多面积被构成织物的纤维所占有。为此,常常又把它称为“表观外表速度”。
It is the gas flow by filtration (m3/min) with dust bag area (M2) ratio, the dimension is m3/min.m2=m/min. This is the unit of velocity, which represents the average velocity of the gas passing through the dust bag, and does not consider that there are many areas of the fabric which are made up of the fabric. For this reason, it is often referred to as "apparent surface velocity".
过滤速度是决定美高梅在线登录网址除尘设备功能的一个很主要的要素。过滤速度太高会形成压损过大,下降除尘功率,使除尘滤袋阻塞和过早损坏。可是,进步过滤速度能够削减布袋除尘器需求的过滤面积,从而能够用较小的除尘设备来处理一样体积的气体。
Filtering speed is a very important factor to determine the function of environmental protection dust removal equipment. The filtration rate is too high will form the pressure loss is too large, the power down dust, dust bag blocking and premature damage. However, increasing the filtration rate can reduce the filter area required by the bag filter, thus being able to process the same volume of gas with a smaller dust removal device.
对某一组规划参数(即美高梅在线登录网址除尘设备型式、清灰组织、除尘布袋纤维材料和织物构造、尘埃性质等)有一个最佳过滤速度。一般,细尘埃比粗尘埃取的过滤速度要低些,较小的除尘器一般选用比大美高梅在线登录网址除尘设备高的过滤速度。脉冲式、反向射流式除尘器能够比振荡式、反向气流式的过滤速度获得高些。
There is an optimal filtration rate for a certain set of planning parameters, i.e., the type of dust removal equipment, dust cleaning, dust bag fabric and fabric structure. In general, fine dust than coarse dust to take the filter speed is lower, the smaller the dust collector is generally higher than the large environmental protection dust removal equipment. The pulse type and reverse jet dust collector can obtain higher filtering speed than the oscillating and reverse air flow.
关于振荡式和反向气流式美高梅在线登录网址除尘设备,用于普通尘埃,过滤速度能够选用0.9m/min。从统筹出资和维护两方面的视点动身,有人推荐饲料和谷物尘埃以及面粉的最大过滤速度可分别为0.98和0.75m/min。
On the oscillation and reverse flow type environmental protection dust removal equipment for ordinary dust, filtration speed can be used 0.9m/min. From the point of view of co-ordination and contribution to the maintenance of two aspects, it was recommended feed and grain dust and flour maximum filtration rate of 0.98 and 0.75m/min.

7 filtration area
进入美高梅在线登录网址除尘设备的气体流量(m3/min)除以所选用的过滤速度(m/min),即得实际需求的织物面积(m2)。因为温度改变,以及空气的额外增减,进人美高梅在线登录网址除尘设备的舍尘气体体积不一定同生产过程所排出的体积一样。假如美高梅在线登录网址除尘设备运用在流量有改变的场合,需求作出判别,究竟是按峰值流量仍是平均流量来核算过滤面积。另外,还应思考美高梅在线登录网址除尘设备除尘布袋织物的储备量,以便进行清灰,检查和修理。
The gas flow rate (m3/min) of the environmental protection dust removal device is divided by the selected filtration rate (m/min), which is the actual demand of the fabric area (M2). Because of the temperature change, as well as the additional changes in the air, into the environmental protection dust removal equipment dust gas volume is not necessarily the same as the volume of the production process. If the environmental protection dust removal equipment used in the flow has changed the situation, the need to make a judgment, whether it is based on the peak flow is still the average flow to calculate the filter area. In addition, consideration should also be given to the environmental protection dust removal equipment dust bag fabric reserves, in order to carry out cleaning, inspection and repair.

一台美高梅在线登录网址除尘设备需求多少分隔室是对比简单断定的。在决定了每个分隔室的除尘布袋面积今后,就要决定最有利的除尘滤袋长度、直径和摆放距离。一般长度的除尘滤袋最佳有不小于50毫米的距离;格外长(如超越3米)的除尘滤袋距离应当更大些。除尘滤袋应当分组,在两组之间留下通道。假如只在一侧有通道,除尘布袋直径为150毫米,每组不该当多于三或四排滤袋;直径为300毫米的每组不该多于二排。假如两边有通道,直径150毫米的不该多于八排,直径300毫米的不该多于四排。通道宽度为450~600毫米。每组除尘滤袋的总数取决于所用的振荡组织。一般,一组滤袋内有一组振荡组织操作。一个分隔室能够包括若干组滤袋。
A number of environmental protection dust removal equipment room is a simple comparison of the determination of the. In the decision of each compartment of the dust bag area in the future, we decided to dust bag length, and the diameter of the most favorable display distance. The general length of the dust bag the best is not less than 50 mm long distance; (e.g. beyond 3 meters) the distance should be more dust bag. Dust bag should be left in the packet channel between the two groups. If there is only on one side of the channel, dust bag diameter of 150 mm, each group should not be more than three or four rows of bags; each 300 mm diameter should not be more than two rows. If both sides of the channel, the diameter of 150 mm should not be more than eight rows, the diameter of 300 mm should not be more than the four row. Channel width of 450 ~ 600 mm. The total number of each filter depends on the oscillation of organization. In general, a group of filter bag has a set of operations organization oscillation. One of the compartments can comprises a plurality of filter bag.
