耐火材料厂出产设备，如粉碎机、筛分机、压砖机等;通常都装有吸尘罩和吸风嘴，汲取含尘空气经过除尘管道进入环保除尘设备进行净化。在扬尘设备上设置吸尘罩和吸风嘴时，通常应考虑如下几个因素：
Refractory material factory production equipment, such as crusher, sieving, press; usually equipped with air suction nozzle and a dust suction hood, absorbing dust air through the filter pipe into the environmental protection equipment for purification. When the dust suction hood and the suction nozzle are arranged on the dust removal equipment, the following factors should be considered:
1、吸尘罩尽量设置在粉尘发作点，但要以不阻碍操作为准则;
1, dust hood as far as possible in the dust attack point, but not to hinder the operation of the guidelines;
2、吸尘罩方位要符合粉尘发出方向;
2, dust cover direction to meet the direction of dust;
3、吸尘罩形状要合乎作业条件和粉尘发作状态。
3, dust hood shape to meet the operating conditions and dust attack state.
例如，压砖机在砖坯成型过程中(如秤料、装料、压砖和出砖)会有粉尘发生，因而，在压砖机砖模两边设置2~4个吸风嘴，将大大削减压砖时粉尘飞扬。另外如干碾机、筛分机吸
For example, in the press molding process (such as weighing, filling, brick and tile) there will be dust, therefore, in the press brick die set 2~4 on both sides of the air suction nozzle, will greatly cut brick dust. In addition, such as dry grinding machine, screening machine suction

耐火材料职业常用到几大环保除尘设备选型介绍
Introduction to several major environmental protection dust removal equipment selection
1、耐火材料用旋风除尘器是一种运用离心力效果环保除尘设备。其除尘原理含尘气体在旋风除尘器内作旋转运动，其粉尘在离心力效果下与气体别离并从出料口排出。
1, the use of cyclone dust collector is a centrifugal effect of environmental protection dust removal equipment. The dust removing principle of the utility model comprises the following steps: the dust containing gas is rotated in the cyclone dust collector, and the dust is separated from the gas outlet under the effect of centrifugal force and discharged from the discharge port.
旋风除尘器首要长处设备结构简略，价格便宜，除尘功率高(可达70~80%)。特别对粉尘粒度大、含尘浓度高含尘气体，有良好除尘效果。因而在耐火材料出产中被广泛运用。但这种除尘器的缺陷是对粒度在5微米以下粉尘别离效果不适合。
Cyclone dust removal equipment, the main advantages of simple structure, cheap, high power (up to 70~80%). Especially for the dust size, dust concentration high dust gas, good dust removing effect. It is widely used in the production of refractory materials. However, the defect of the dust remover is not suitable for the effect of particle size below 5 microns.
2、耐火材料用袋式除尘器是一种较大型环保除尘设备。近年来，这种除尘器在耐火材料厂运用的不断添加。它的长处是除尘功率高，可达95%以上;可处理含尘气体的浓度范围大，由数毫克/m3至数千毫克/m3;最小除尘粒度可达0.1微米。因而，它是现在耐火材料出产中对比理想的除尘设备。袋式除尘器根本作业原理是含尘气体从进气口进入除尘器，经过滤袋将粉尘残留在滤袋外表面，净气则从排气口排出。袋式除尘器开始作业时，滤袋外表面附着粉尘少，所以气体透过滤袋很容易。但随着附着在滤袋外表面粉尘添加，使气体经过滤袋阻力添加，抵达必定程度后就会影响除尘效果，因而需求采纳各种办法抖落滤袋上粉尘，以保证气体正常经过。现在运用较多的是选用电磁操控器或机械操控器，使压缩空气通过文氏管向滤袋内部作瞬时(通常为0.1 秒)喷吹(称之为脉冲)，构成滤袋向外激烈扩大使粉尘掉落。通常将选用电磁阀操控称为电磁脉冲;用机械操控器操控称为机械脉冲。这两种脉冲袋式除尘器在中国耐火材料厂中均被选用。
2, the bag type dust collector is a kind of environmental protection dust removal equipment. In recent years, the application of this kind of dust collector in refractory material factory. It has the advantage of high dust power, up to more than 95%; can handle the concentration range of dust containing gas from a few milligrams of /m3 to thousands of milligrams of /m3; minimum dust size up to 0.1 microns. As a result, it is an ideal dust removal equipment in the production of refractory materials. Bag type dust collector basic working principle is dust containing gas from the inlet into the filter, the filter bag dust remaining on the surface of filter bag, net gas is discharged from the exhaust port. Bag type dust collector began operation, the outer surface of the bag attached less dust, so the gas through the bag easily. But with the surface dust in the bag outside the gas bag after add, add resistance, dust will affect the degree of effect must arrive, so need to adopt various measures to shake off the bag dust, in order to ensure the normal gas after. It is used mostly choose electromagnetic control device or mechanical control device, the compressed air to the filter bag instantaneously through the venturi (usually 0.1 seconds) injection (called pulse), a fierce outward expansion of falling dust bag. Solenoid valve is usually used to control the electromagnetic pulse is called; with mechanical manipulation of mechanical pulse. The two kinds of pulse bag filter are used in the refractory factory of china.
3、耐火材料用空气反转除尘器。这种环保除尘设备的外形像水平放着的筒。在筒内安有特别导向叶片，含尘气体由进口以切线方向进入除尘器，绕水平轴反转数次，粉尘受离心力效果而被别离至筒壁;在筒下部有水，水随气体运动而在筒壁上构成水膜而沾集被别离出来粉尘，余下来随气体运动粉尘，到下面急剧转换方向时，又被浸入水中。这么经数次循环，可到达除尘目的。这种除尘器，用在粉尘粒度为5微米以上含尘气体除尘时功率较高;若用在含尘气体中粉尘微粒在1微米以下除尘时，可在空气反转除尘器进口处，先喷雾使微粒凝聚，再进行除尘，能够提高除尘功率。这种除尘器缺陷是别离出来的粉尘已成为悬浮液泥浆，给粉尘回收带来艰难，别的，这种除尘器不可用于对水硬性粉尘的别离。
3, air reverse dust remover for refractories. The appearance of the environmental protection dust removing device is like a horizontal cylinder. A special guide vane is in the cylinder, dust containing gas from imported into the dust in the tangential direction around a horizontal axis, reversed several times, due to the centrifugal force and the effect of dust is separated to the cylinder wall; the water in the barrel bottom, with water and gas motion in the cylinder wall of water film and James set was separated dust. The remaining dust with the gas movement, to the abrupt change of direction, and is immersed in water. After several cycles, can reach the purpose of dust. This dust remover used in dust particle size of 5 microns above the dust gas high power dust; if used in dust containing gas dust particles in 1 microns dust in the air, can reverse precipitator inlet, first spray particle coagulation, then dust, dust can improve power. The defect of the dust remover is that the separated dust has become a suspension slurry, which brings difficulties to dust recovery.
