具体实施方式detailed description
下面结合附图对本实用新型作进一步阐述：Below in conjunction with accompanying drawing, the utility model is further elaborated:
由于工业废气的种类繁多，各行各业产生的废气的成份不一，因此本实用新型主要是针对燃煤、燃油火电厂产生的工业废气进行净化处理。这类工业废气主要含有煤屑、油脂、碳烟、NOx(如NO、NO2等)、SO2、CO和碳氢化合物。Due to the various types of industrial waste gas and the different components of the waste gas produced by various industries, the utility model is mainly aimed at purifying the industrial waste gas produced by coal-fired and oil-fired power plants. This type of industrial waste gas mainly contains coal dust, grease, soot, NO x (such as NO, NO 2 , etc.), SO 2 , CO and hydrocarbons.
如图1所示的一种工业废气处理系统，包括沿着工业废气输送的方向依次设置的除尘装置1、氧化催化转换器2、除碳烟过滤装置3、去氮装置4和除硫装置5。As shown in Figure 1, an industrial waste gas treatment system includes a dust removal device 1, an oxidation catalytic converter 2, a soot removal filter device 3, a nitrogen removal device 4 and a sulfur removal device 5 arranged in sequence along the direction of industrial waste gas transportation .
除尘装置1我们可以选择市面上常后的静电除尘器或者其它除尘设备，在本实施例中，除尘装置1包括设置在封闭箱体内的金属过滤网11，由于此处的除尘装置1主要是去除颗粒较大的煤屑等，因此我们采用金属过滤网11，金属过滤网11的目数在60～180之间，金属过滤网11倾斜设置，即金属过滤网11与水平面呈一定的夹角，封闭箱体的底部设置有集尘盒12。金属过滤网11倾斜设置的目的是使被金属过滤网11阻挡的粉屑更容易掉入集尘盒12中。Dust removal device 1 We can choose the electrostatic precipitator or other dust removal equipment that are often on the market. In this embodiment, the dust removal device 1 includes a metal filter screen 11 arranged in a closed box. Because the dust removal device 1 here is mainly to remove Larger particles of coal dust, etc., so we use metal filter screen 11, the mesh number of metal filter screen 11 is between 60 and 180, and the metal filter screen 11 is installed obliquely, that is, the metal filter screen 11 and the horizontal plane are at a certain angle. The bottom of the closed box is provided with a dust box 12 . The purpose of the inclined setting of the metal filter screen 11 is to make the dust blocked by the metal filter screen 11 fall into the dust box 12 more easily.
氧化催化转换器2利用催化剂的作用将工业废气中的CO和碳氢化合物转化为CO2和水，催化剂采用金属铂、钯或铑。Oxidation catalytic converter 2 converts CO and hydrocarbons in industrial waste gas into CO2 and water by using a catalyst, and the catalyst uses metal platinum, palladium or rhodium.
除碳烟过滤装置3包括沿着工业废气输送方向叠加设置的2块以上的耐热陶瓷砖31。在本实施例中，耐热陶瓷砖31采用碳化硅制成。耐热陶瓷砖31布满蜂窝孔，工业废气在通过这些蜂窝孔时，碳烟中的碳粒子会粘附在耐热陶瓷砖31上，从而达到去除工业废气中的碳烟的目的，达到净化气体的作用。耐热陶瓷砖31在使用一段时间后，蜂窝孔会逐渐被堵塞，从而逐渐失效。为了解决这个问题，在本实施例中，我们在除碳烟过滤装置3的出气口处设置有一流量传感器6，该流量传感器6用于检测气体的流量，并且在耐热陶瓷砖31底部和/或周围设置有加热机构32。在本实施例中，加热机构32采用电加热丝，当然在实际使用中，我们也可以根据生产的实际条件采用燃气加热等其它方法。在使用的过程中，当流量传感器6检测到气体的流量较小时，便可判断耐热陶瓷砖31上的蜂窝孔大部分被碳粒子堵塞了，此时可启动加热机构32对耐热陶瓷砖31进行加热，从而将耐热陶瓷砖31上的碳粒子燃烧掉，使耐热陶瓷砖31恢复过滤的功能。The soot removal filter device 3 includes more than two heat-resistant ceramic tiles 31 stacked along the conveying direction of industrial waste gas. In this embodiment, the heat-resistant ceramic brick 31 is made of silicon carbide. The heat-resistant ceramic tile 31 is covered with honeycomb holes. When the industrial waste gas passes through these honeycomb holes, the carbon particles in the soot will adhere to the heat-resistant ceramic tile 31, so as to achieve the purpose of removing the soot in the industrial waste gas and achieve purification. The role of gas. After the heat-resistant ceramic tile 31 is used for a period of time, the honeycomb holes will be gradually blocked, thereby gradually failing. In order to solve this problem, in this embodiment, we are provided with a flow sensor 6 at the gas outlet of the soot removal filter device 3, and the flow sensor 6 is used to detect the flow of gas, and at the bottom of the heat-resistant ceramic tile 31 and/or Or a heating mechanism 32 is arranged around it. In this embodiment, the heating mechanism 32 adopts an electric heating wire, of course, in actual use, we can also adopt other methods such as gas heating according to the actual production conditions. In the process of use, when the flow sensor 6 detects that the flow rate of the gas is small, it can be judged that most of the honeycomb holes on the heat-resistant ceramic tile 31 are blocked by carbon particles. 31 is heated, so that the carbon particles on the heat-resistant ceramic tile 31 are burned off, and the heat-resistant ceramic tile 31 recovers the filtering function.
去氮装置4包括一还原反应箱，还原反应箱的底部设置有氨气进气口41，还原反应箱的中部设置有外表涂敷有催化剂的反应器42，氨气、NOx和氧气在反应器42上发生化学还原反应，生成氮气和水，从而达到去除NOx的目的。The denitrification device 4 includes a reduction reaction box, the bottom of the reduction reaction box is provided with an ammonia gas inlet 41, and the middle part of the reduction reaction box is provided with a reactor 42 coated with a catalyst, and ammonia, NOx and oxygen react A chemical reduction reaction occurs on the device 42 to generate nitrogen and water, thereby achieving the purpose of removing NOx .
除硫装置5为一水池，水池内盛放有饱和NaHCO3溶液，工业废气中的SO2会与NaHCO3溶液发生反应，从而去除掉SO2。为达到去除工业废气中油脂的目的，工业废气处理系统还包括一冷却池7，冷却池7内盛有水，冷却池7内还设置有若干条冷却管71，冷却管71内通有冷却液。从而使冷却池7内的冷却管71附近的水温度较低，当工业废气通过冷却池7时，油脂会凝固，从而达到去除工业废气中油脂的目的。The desulfurization device 5 is a water pool, which contains a saturated NaHCO 3 solution, and the SO 2 in the industrial waste gas will react with the NaHCO 3 solution to remove the SO 2 . In order to achieve the purpose of removing grease from industrial waste gas, the industrial waste gas treatment system also includes a cooling pool 7, which contains water, and several cooling pipes 71 are arranged in the cooling pool 7, and cooling liquid is passed through the cooling pipe 71 . Therefore, the temperature of the water near the cooling pipe 71 in the cooling pool 7 is lower, and when the industrial waste gas passes through the cooling pool 7, the grease will solidify, thereby achieving the purpose of removing the grease in the industrial waste gas.
