Description

一种多工况烟气集中独立净化处理系统及其控制方法Multi-condition flue gas concentration independent purification treatment system and control method thereof 技术领域Technical field
本发明涉及一种活性炭烟气净化系统及其控制方法，具体涉及一种活性炭处理多工况烟气净化系统及其控制方法，属于气体净化技术领域。The invention relates to an activated carbon flue gas purification system and a control method thereof, in particular to an activated carbon treatment multi-condition flue gas purification system and a control method thereof, and belongs to the technical field of gas purification.
背景技术Background technique
钢铁企业是整个国民经济的支柱企业，但是，它为经济发展做出重要贡献的同时，也伴随着严重的污染大气的问题。钢铁企业内有很多工序都会产生烟气排放，例如，烧结、球团、炼焦、炼铁、炼钢和轧钢等工序，每个工序排放的烟气中含有大量的粉尘、SO 2和NO X等污染物。污染烟气被排放到大气中后，不仅污染环境，还会对人体健康构成威胁。为此，钢铁企业通常采用活性炭烟气净化技术，即在烟气净化装置中盛放具有吸附功能的物料(例如活性炭)吸附烟气，以实现对每个工序排放的烟气的净化处理。 Iron and steel enterprises are the pillars of the entire national economy. However, while making important contributions to economic development, they are also accompanied by serious pollution problems. There are many processes in the steel industry that generate smoke emissions, such as sintering, pelletizing, coking, iron making, steel making and steel rolling. The flue gas emitted in each process contains a large amount of dust, SO 2 and NO X. Contaminants. When polluted smoke is emitted into the atmosphere, it not only pollutes the environment, but also poses a threat to human health. For this reason, iron and steel enterprises usually adopt activated carbon flue gas purification technology, that is, the flue gas purification device contains a material having an adsorption function (for example, activated carbon) to adsorb flue gas, so as to purify the flue gas discharged from each process.
现有钢铁企业的活性炭烟气净化技术应用在烟气净化系统中，图1示出了一种活性炭烟气净化系统，系统包括：用于净化原烟气、排出污染活性炭的吸附塔，用于活化污染活性炭、排出活化活性炭的解析塔，用于回收利用污染物SO 2和NO X的制酸子系统(图中未示出)，以及，两台活性炭输送机。系统运行时，第一输送机输送的活性炭，经由进料装置进入吸附塔，在吸附塔中形成活性炭料层，同时，含有污染物SO 2和NO X的原烟气源源不断地进入吸附塔，并进一步进入活性炭料层，使得原烟气中的SO 2和NO X被活性炭吸附，从而成为洁净烟气排出。吸附塔的排料装置持续工作，将吸附塔内富集有SO 2和NO X的污染活性炭排出，再由第二输送机输送至解析塔。第二输送机输输送的污染活性炭经由进料装置进入解析活塔，使得SO 2和NO X等污染物从污染活性炭中析出，从而成为活化活性炭。排料装置将解析塔中的活化活性炭排出，由第一输送机＝输送到吸附塔循环使用。 The activated carbon flue gas purification technology of the existing steel enterprises is applied in the flue gas purification system, and FIG. 1 shows an activated carbon flue gas purification system, which comprises: an adsorption tower for purifying the original flue gas and discharging the polluted activated carbon, for activated charcoal pollution, discharged desorber activated carbon for recycling acid subsystem (not shown) SO 2 and NO X pollutants, as well, the two conveyors activated carbon. When the system is running, the first conveyor transporting the activated carbon into the adsorber via the feed means, the material layer is formed of activated carbon in the adsorption tower while containing SO 2 and primary flue gas NO X pollutants continue to enter the adsorption column, and further into the active carbon material layer, so that the original flue gas sO 2 and NO X adsorbed by activated charcoal, thus becoming the clean flue gas is discharged. Discharge means continuous operation of the adsorption tower, the adsorption tower enriched with SO 2 and NO X pollution discharge of activated carbon, and then conveyed by the second conveyor to the desorber. A second output conveyor conveying contaminated activated carbon into the analytical device via a live feed column, so that the SO 2 and NO X and other contaminants from a contaminated precipitation of the activated carbon, thereby becoming activated carbon. The discharge device discharges the activated activated carbon in the analytical tower, and is transported by the first conveyor = to the adsorption tower for recycling.
图1所示活性炭烟气净化系统的一种应用方式是，企业在每个烟气排放工序均设置一套吸附塔和一套解析塔，每对吸附塔和解析塔同时工作，以完成对企业每个工序产生的污染烟气的净化工作。由于钢铁企业每个工序的规模以及产生的烟气量不同，为了实现最佳的烟气净化效果，不同规模的工序需要设置规模匹配的烟气净化装置，导致钢铁企业内设置的烟气净化装置的种类较多。而为每个烟气净化装置分别配置独立的活性炭解析塔，导致钢铁企业内活性炭解析塔的设置数量过多，使得钢铁企业内烟气净化系统的整体结构复杂，且每一工序产生的烟气被单独处理，导致烟气净化系统的运行效率低，对于解析塔的大量投入，既浪费设备资源，又增加企业的管理难度。 因此，如何提供一种能够高效处理烟气的烟气净化系统成为本领域亟待解决的问题。One application mode of the activated carbon flue gas purification system shown in Figure 1 is that the enterprise sets a set of adsorption towers and a set of analytical towers in each flue gas discharge process, and each pair of adsorption towers and analytical towers work simultaneously to complete the enterprise Purification of contaminated flue gas produced by each process. Due to the scale of each process and the amount of smoke generated by the steel company, in order to achieve the best flue gas purification effect, different scale processes need to set up a scale-matched flue gas purification device, resulting in a flue gas purification device installed in the steel enterprise. There are many types. Separate activated carbon analysis towers are arranged for each flue gas purification device, resulting in an excessive number of activated carbon analysis towers in the steel enterprise, which makes the overall structure of the flue gas purification system in the steel enterprise complex, and the flue gas generated in each process. Being treated separately, the operation efficiency of the flue gas purification system is low, and the large investment in the analytical tower wastes equipment resources and increases the management difficulty of the enterprise. Therefore, how to provide a flue gas purification system capable of efficiently treating flue gas has become an urgent problem to be solved in the art.
现有技术中，存在一些将多工序产生的烟气合并在一起之后，再通过活性炭吸附塔进行净化处理。这种工艺存在以下缺陷：1、每一种工序产生的烟气中污染物的含量不同，多工工序的烟气合并之后，对于污染物含量小的烟气经过混合后，污染物含量增加，增加了吸附塔的处理负荷；2、如果简单把不同工况烟气集中在一个末端净化吸附装置中，会产生流场相互干扰，而影响主工艺的排放独特性，同时各工况的生产制度不同，简单的集中烟气，会影响主工艺的生产稳定性或影响末端净化装置的稳定运行和安全性；3、国家和行业对于各种工序产生的烟气的排放标准不同，例如焦化工序烟气的排放标准为二氧化硫含量低于30mg/Nm 3、氮氧化物含量低于150mg/Nm 3，但是对于烧结工序，排放标准为二氧化硫含量低于180mg/Nm 3、氮氧化物含量低于300mg/Nm 3，超低排放标准要求二氧化硫含量低于35mg/Nm 3，氮氧化物含量低于50mg/Nm 3。因此，不同工序产生的烟气，经过活性炭吸附塔处理后的排放烟气的污染物排放标准不同，如果将多工序的烟气合并之后，通过活性炭吸附塔进行净化处理，处理后的排放的烟气中污染物的含量相同，但是如果以所有工序烟气排放标准中的最低标准排放，显然污染空气，不符合行业标准；如果以所有工序烟气排放标准中的最高标准排放，则极大的增加了运行成本。 In the prior art, there are some flue gases generated by a plurality of processes, and then purified by an activated carbon adsorption tower. This process has the following defects: 1. The content of pollutants in the flue gas produced by each process is different. After the flue gas of the multiplex process is combined, the pollutant content increases after the flue gas with a small pollutant content is mixed. The processing load of the adsorption tower is increased; 2. If the flue gas of different working conditions is simply concentrated in one end purification adsorption device, the flow field mutual interference will be generated, and the emission uniqueness of the main process will be affected, and the production system of each working condition will be generated. Different, simple concentrated flue gas will affect the production stability of the main process or affect the stable operation and safety of the end purification device; 3. The national and industry have different emission standards for flue gas generated by various processes, such as coking process smoke. The gas emission standard is sulfur dioxide content less than 30mg/Nm 3 and nitrogen oxide content less than 150mg/Nm 3 , but for the sintering process, the emission standard is sulfur dioxide content less than 180mg/Nm 3 and nitrogen oxide content less than 300mg/ Nm 3 , ultra-low emission standards require a sulfur dioxide content of less than 35 mg/Nm 3 and a nitrogen oxide content of less than 50 mg/Nm 3 . Therefore, the flue gas generated in different processes is different from the pollutant emission standards of the flue gas discharged through the activated carbon adsorption tower. If the flue gas of the multi-process is combined, the activated carbon adsorption tower is used for purification treatment, and the discharged smoke is treated. The content of pollutants in the gas is the same, but if it is discharged at the lowest standard of all process flue gas emission standards, it is clear that the air is polluted and does not meet the industry standards; if it is discharged at the highest standard of all process flue gas emission standards, it is extremely Increased operating costs.

在本发明中，活性炭吸附单元或单元组也可以称为活性炭吸附单元或活性炭吸附单元组。活性炭吸附单元(或活性炭吸附单元组)为一个完整的活性炭吸附设备，功能类似于现有技术中一个完整的活性炭吸附塔。集成塔是将多个独立的活性炭吸附单元或单元组并联设置在一起，实现多个独立的活性炭吸附单元的集中体，类似于将多个活性炭吸附塔并联设置在一起。但是，本发明的集成塔包括了多个独立的活性炭吸附单元或单元组，空间利用率高，节约成本；同时，由于多个活性炭吸附单元或单元组紧密设置，而活性炭吸附是在高温条件下进行的，集成塔的设计减少了热量的散失，提高了活性炭吸附处理烟气的效率。In the present invention, the activated carbon adsorption unit or unit group may also be referred to as an activated carbon adsorption unit or an activated carbon adsorption unit group. The activated carbon adsorption unit (or activated carbon adsorption unit group) is a complete activated carbon adsorption unit, which functions similarly to a complete activated carbon adsorption tower in the prior art. The integrated tower is a concentrator in which a plurality of independent activated carbon adsorption units or unit groups are arranged in parallel to realize a plurality of independent activated carbon adsorption units, which are similarly arranged in parallel with a plurality of activated carbon adsorption towers. However, the integrated tower of the present invention comprises a plurality of independent activated carbon adsorption units or unit groups, which has high space utilization and cost saving; meanwhile, since a plurality of activated carbon adsorption units or unit groups are closely arranged, the activated carbon adsorption is under high temperature conditions. In the implementation, the design of the integrated tower reduces heat loss and improves the efficiency of activated carbon adsorption treatment of flue gas.
作为优选，解析系统包括，所述活性炭解析塔，用于控制进入解析塔内污染活性炭流量的给料装置，用于将解析塔内经过活化处理后的活化活性炭排出的排料装置，用于对所述排料装置排出的活化活性炭进行筛分的筛分装置，用于收集经筛分装置后得到的活化活性炭的活化活性炭仓，设置在各工序对应的烟气净化装置的出口端与给料装置之间的总活性炭仓，所述总活性炭仓用于收集各工序中烟气净化装置排放的污染活性炭，设置在所述总活性炭仓与给料装置之间的皮带秤，所述皮带秤用于将总活性炭仓内的污染活性炭输送至解析塔，以及，设置在总活性炭仓上方的新活性炭补充装置。所述新活性炭补充装置用于向总活性炭仓内补充新活性炭，也就是向解析塔内额外补充活性炭。Preferably, the analytical system comprises: the activated carbon analytical tower, a feeding device for controlling the flow rate of the contaminated activated carbon entering the analytical tower, and a discharging device for discharging the activated activated carbon in the analytical tower after the activation treatment, for The sieving device for sieving activated activated carbon discharged from the discharge device is used for collecting the activated activated carbon activated carbon activated by the sieving device, and is disposed at the outlet end and the feeding material of the flue gas purification device corresponding to each process a total activated carbon cartridge between the devices, the total activated carbon cartridge is used to collect the polluted activated carbon discharged from the flue gas purification device in each process, and a belt scale disposed between the total activated carbon cartridge and the feeding device, the belt scale The contaminated activated carbon in the total activated carbon cartridge is transported to the analytical tower, and a new activated carbon replenishing device is disposed above the total activated carbon cartridge. The new activated carbon replenishing device is used for replenishing the new activated carbon into the total activated carbon storage tank, that is, adding additional activated carbon to the analytical tower.
在本发明中，每个烟气排放工况独立的设置1个或多个活性炭吸附单元或单元组，处理多个工况烟气的活性炭吸附单元或单元组设置一个集中处理污染活性炭的集中解析塔，对应全厂范围内部分或全部的吸附塔，使解析塔与活性炭吸附单元或单元组之间具一对多的对应关系。In the present invention, one or more activated carbon adsorption units or unit groups are independently set for each flue gas discharge working condition, and an activated carbon adsorption unit or unit group for treating a plurality of working condition flue gases is provided with a centralized analysis of concentrated activated carbon. The tower corresponds to some or all of the adsorption towers in the whole plant, so that the analytical tower has a one-to-many correspondence relationship with the activated carbon adsorption unit or the unit group.
此外，由于进入活性炭吸附单元或单元组的原烟气流量、原烟气中污染物的含量以及吸附塔中活性炭的循环流量是影响烟气净化效果的主要因素，例如，当原烟气流量增大和/或原烟气中污染物含量增大时，活性炭吸附单元或单元组中活性炭的循环流量需同时定量增大，才能保证烟气净化效果，否则，就会出现活性炭已经饱和而原烟气中一部分污染物还未被吸附的现象，从而降低净化效果。因此，本发明提出根据每一个活性炭吸附单元或单元组处理一处工况的烟气，检测该工况产生的烟气中污染物的含量、该工况处产生烟气的流量，得到该工况产生烟气中污染物的流量；根据该工况产生烟气中污染物的流量，确定处理该工况产生烟气的活性炭吸附单元或单元组内活性炭的流量。平衡吸附塔中活性炭的循环流量与原烟气流量等因素的关系。In addition, the flow rate of the raw flue gas entering the activated carbon adsorption unit or unit group, the content of pollutants in the original flue gas, and the circulating flow rate of the activated carbon in the adsorption tower are the main factors affecting the purification effect of the flue gas, for example, when the original flue gas flow rate is increased. When the content of pollutants in the primary and/or raw flue gas increases, the circulating flow rate of activated carbon in the activated carbon adsorption unit or unit group needs to be quantitatively increased at the same time to ensure the purification effect of the flue gas. Otherwise, the activated carbon is saturated and the original flue gas appears. A part of the pollutants have not been adsorbed, thereby reducing the purification effect. Therefore, the present invention proposes to treat the flue gas of a working condition according to each activated carbon adsorption unit or unit group, and detect the content of the pollutants in the flue gas generated by the working condition, and the flow rate of the flue gas generated at the working condition, and obtain the work. The flow rate of the pollutants in the flue gas is generated; according to the working condition, the flow rate of the pollutants in the flue gas is generated, and the flow rate of the activated carbon in the activated carbon adsorption unit or the unit group that generates the flue gas is determined. The relationship between the circulating flow rate of activated carbon in the adsorption tower and the original flue gas flow rate is balanced.
其次，解析塔对多个活性炭吸附单元或单元组排出的污染活性炭集中活化处理，由于多个活性炭吸附单元或单元组规模各异，其对污染活性炭的排料流量大小也各不相同，另外，解析塔处理的污染活性炭来自设置在不同工序的活性炭吸附单元或单元组，设备故障、生产计划调整等因素，使得不同工序的吸附塔输出的活性炭数量的稳定性也会产生波动，因此，通过根据处理i工况产生烟气的每个活性炭吸附单元或单元组内活性炭的流量，确定处理该工况烟气活性炭吸附单元或单元组的进料装置和排料装置的流量、解析塔内活性炭的流量；从而控制解析塔对污染活性炭的处理能力与多个吸附塔活性炭排出量的平衡。Secondly, the analytical tower is used for centralized activation treatment of polluted activated carbon discharged from a plurality of activated carbon adsorption units or unit groups. Since a plurality of activated carbon adsorption units or unit groups have different scales, the discharge flow rate of the contaminated activated carbon is also different. The polluted activated carbon treated by the analytical tower comes from the activated carbon adsorption unit or unit group set in different processes, equipment failure, production plan adjustment and other factors, so that the stability of the activated carbon output from the adsorption tower of different processes will also fluctuate, therefore, according to the basis The flow rate of activated carbon in each activated carbon adsorption unit or unit group for generating flue gas in the i working condition is determined, and the flow rate of the feeding device and the discharging device for treating the flue gas activated carbon adsorption unit or unit group of the working condition is determined, and the activated carbon in the column is analyzed. The flow rate; thereby controlling the balance between the treatment capacity of the analytical tower for the contaminated activated carbon and the amount of activated carbon discharged from the plurality of adsorption towers.
在本发明中，净化处理系统同时处理多工况产生的烟气，该净化处理系统包括多个活性炭吸附单元或单元组和一个解析塔，多个活性炭吸附单元或单元组和一个解析塔设置在同一区域内，多个活性炭吸附单元或单元组和解析塔之间的活性炭运输通过2条活性炭输送设备(第一活性炭输送设备和第二活性炭输送设备)实现，其中第一活性炭输送设备将多个活性炭吸附单元或单元组排出的吸附了污染物的活性炭输解析塔，第二活性炭输送设备将解析完的活性炭(包括活性炭吸附单元或单元组输送来的活性炭和额外补充的新的活性炭)输送至各个活性炭吸附单元或单元组，通过2条活性炭输送设备就可以完成整个活性炭的运输和输送。这就解决了将活性炭吸附单元或单元组分散布置的缺陷，现有技术中，将活性炭吸附单元或单元组分散布置，需要将解析完的活性炭挨个输送至各个活性炭吸附单元或单元组，由于钢铁企业布局较广，占地宽，输送距离较远，而且活性炭的使用是长期和连续的，运输活性炭成本较高，而且需要设计专门的运输路线，浪费资源。也改变了现有技术中一个活性炭吸附塔配套一个解析塔的传统设计，本发明一个解析塔配套多个活性炭吸附单元或单元组，减少了解析塔的投入，同时提高了解析塔的利用率和工作效率。In the present invention, the purification treatment system simultaneously processes the flue gas generated by the multi-condition, the purification treatment system includes a plurality of activated carbon adsorption units or unit groups and a resolving tower, and the plurality of activated carbon adsorption units or unit groups and one analytical tower are disposed at In the same area, the activated carbon transportation between multiple activated carbon adsorption units or unit groups and the analytical tower is realized by two activated carbon conveying equipments (first activated carbon conveying equipment and second activated carbon conveying equipment), wherein the first activated carbon conveying equipment will be multiple The activated carbon adsorption unit or the unit group discharges the activated carbon transport analytical tower adsorbed by the pollutant, and the second activated carbon conveying device transports the analyzed activated carbon (including the activated carbon adsorption unit or the activated carbon fed from the unit group and the additional supplemented new activated carbon) to Each activated carbon adsorption unit or unit group can complete the transportation and transportation of the entire activated carbon through two activated carbon conveying equipment. This solves the defect of dispersing the activated carbon adsorption unit or the unit group. In the prior art, the activated carbon adsorption unit or the unit group is dispersedly arranged, and the analyzed activated carbon is transported to each activated carbon adsorption unit or unit group, due to steel. The enterprise has a wide layout, covers a wide area, and has a long transmission distance. The use of activated carbon is long-term and continuous. The cost of transporting activated carbon is high, and it is necessary to design a special transportation route and waste resources. The conventional design of an analytical column for an activated carbon adsorption tower in the prior art is also changed. The analytical tower of the present invention is equipped with a plurality of activated carbon adsorption units or units, which reduces the input of the analytical tower and improves the utilization rate of the analytical tower. Work efficiency.
在本发明中，多工况产生的烟气通过烟气输送管道输送至净化处理系统的活性炭吸附单元或单元组，其中，每一处工况产生的烟气通过一根独立的烟气输送管道输送至一个或多个独立的活性炭吸附单元或单元组，也就是说一个或多个活性炭吸附单元或单元组处理一处工况产生的烟气，每一处工况产生的烟气独立处理。烟气单独处理的设计，灵活的适应了各个工序产生烟气中污染物含量不同、排放标准不同的问题。例如：焦化工序产生的烟气中，二氧化硫的含量为100mg/Nm 3左右、氮氧化物含量为300-1500mg/Nm 3；对于烧结工序产生的烟气中，二氧化硫的含量为400-2000mg/Nm 3、氮氧化物含量为300-450mg/Nm 3；炼铁工序产生的烟气中，二氧化硫的含量为80-150mg/Nm 3、氮氧化物含量为50-100mg/Nm 3。但是，国家和相关行业对不同工序产生的烟气的排放标准也不同，焦化工序排放烟气中，二氧化硫的含量低于30mg/Nm 3左右、氮氧化物含量低于150mg/Nm 3；对于烧结工序排放烟气中，二氧化硫的含量低于180mg/Nm 3、氮氧化物含量低于300mg/Nm 3，目前烧结烟气超低排放标准，要求二氧化硫的含量低于35mg/Nm 3，氮氧化物含量低于50mg/Nm 3；炼铁工序排放烟气中，二氧化硫的含量低于100mg/Nm 3、氮氧化物含量低于300mg/Nm 3。如果将所有工序的烟气直接混合(或者合并)之后在一起通过吸附处理，无形的增大了吸附塔的处理量。例如，由于焦化工序中产生的烟气中二氧化硫的含量少，烧结工序中产生的烟气中二氧化硫多，混合后，导致焦化工序烟气中的二氧化硫增加，增大了活性炭吸附塔处理高二氧化硫含量烟气的处理量。此外，不同工序产生的烟气中各组分(例如二氧化硫和氮氧化物)的含量不同，处理不同工序产生的烟气的侧重点不同。比如：在焦化工艺、烧结工艺、炼铁工艺这三种工艺中，任何一种工艺产生的烟气都需要经过脱硫和脱销处理，致使每一种工艺产生的烟气中污染物的含量都低于国家规定的排放标准才能排放。但是，由于工艺的原料、环境、处理目的等因素的不同，焦化工艺、烧结工艺、炼铁工艺这三种工艺产生的烟气中污染物的含量不同，国家对这三种工艺产生的烟气规定的排放标准也不同。 In the present invention, the flue gas generated by the multiple operating conditions is sent to the activated carbon adsorption unit or unit group of the purification treatment system through the flue gas conveying pipeline, wherein the flue gas generated by each working condition passes through an independent flue gas conveying pipeline. It is sent to one or more independent activated carbon adsorption units or units, that is to say, one or more activated carbon adsorption units or units are used to treat the flue gas generated in one working condition, and the flue gas generated in each working condition is treated independently. The design of the flue gas treatment alone flexibly adapts to the problems of different pollutants in the flue gas and different emission standards in each process. For example, in the flue gas generated by the coking process, the content of sulfur dioxide is about 100 mg/Nm 3 and the content of nitrogen oxide is 300-1500 mg/Nm 3 ; for the flue gas generated in the sintering process, the content of sulfur dioxide is 400-2000 mg/Nm. 3. The nitrogen oxide content is 300-450 mg/Nm 3 ; the flue gas generated in the iron making process has a sulfur dioxide content of 80-150 mg/Nm 3 and a nitrogen oxide content of 50-100 mg/Nm 3 . However, the national and related industries have different emission standards for flue gas generated by different processes. In the coking process, the sulfur dioxide content is less than 30 mg/Nm 3 and the nitrogen oxide content is less than 150 mg/Nm 3 ; In the process exhaust gas, the content of sulfur dioxide is less than 180mg/Nm 3 and the content of nitrogen oxide is less than 300mg/Nm 3 . Currently, the ultra-low emission standard of sintering flue gas requires that the content of sulfur dioxide is less than 35mg/Nm 3 , nitrogen oxides. The content is less than 50 mg/Nm 3 ; the sulfur dioxide content in the ironmaking process is less than 100 mg/Nm 3 and the nitrogen oxide content is less than 300 mg/Nm 3 . If the flue gases of all the processes are directly mixed (or combined) and then passed through the adsorption treatment together, the treatment amount of the adsorption tower is invisibly increased. For example, since the content of sulfur dioxide in the flue gas generated in the coking process is small, the sulfur dioxide generated in the flue gas generated in the sintering process is large, and after mixing, the sulfur dioxide in the flue gas in the coking process is increased, and the high sulfur dioxide content in the activated carbon adsorption tower is increased. The amount of smoke processed. In addition, the content of each component (such as sulfur dioxide and nitrogen oxides) in the flue gas generated by different processes is different, and the focus of the flue gas generated by the different processes is different. For example, in the three processes of coking process, sintering process and ironmaking process, the flue gas generated by any one of the processes needs to be subjected to desulfurization and out-of-stock treatment, so that the content of pollutants in the flue gas generated by each process is low. It can only be discharged under the national emission standards. However, due to different factors such as the raw materials, environment, and treatment purpose of the process, the coking process, the sintering process, and the ironmaking process produce different amounts of pollutants in the flue gas, and the state produces flue gas from the three processes. The prescribed emission standards are also different.
焦化工艺和烧结工艺相比较：焦化工序产生的烟气中，二氧化硫含量较少，氮氧化物的含量较高，那么在吸附处理过程中，侧重点是处理氮氧化物，在活性炭吸附单元或单元组中，需要喷入的氨气量较大；烧结工序产生的烟气中，二氧化硫含量较多，氮氧化物的含量较少，那么在吸附处理过程中，侧重点是处理二氧化硫，在活性炭吸附单元或单元组中，需要喷入的氨气量较小。The coking process is compared with the sintering process: in the flue gas generated by the coking process, the sulfur dioxide content is less, and the content of nitrogen oxides is higher, then in the adsorption process, the focus is on the treatment of nitrogen oxides, in the activated carbon adsorption unit or unit In the group, the amount of ammonia gas to be injected is large; in the flue gas generated in the sintering process, the sulfur dioxide content is large, and the content of nitrogen oxides is small, then in the adsorption treatment process, the focus is on the treatment of sulfur dioxide, in the activated carbon adsorption unit. Or the amount of ammonia that needs to be injected in the unit group is small.
炼铁工序产生的烟气中，二氧化硫含量和氮氧化物的含量均较低，那么在吸附处理过程中，该类烟气相对焦化和烧结产生的烟气来说，比较容易处理，只需要进行简单的脱硫和脱销处理即可排放；如果将这一部分的烟气与焦化和/或烧结产生的烟气混合之后再进行处理，显然增大了净化吸附系统的处理量。In the flue gas produced by the ironmaking process, the content of sulfur dioxide and the content of nitrogen oxides are both low, so in the adsorption process, the smoke generated by the coke gasification and sintering is relatively easy to handle, and only needs to be carried out. Simple desulfurization and out-of-stock treatment can be discharged; if this part of flue gas is mixed with coking and/or sintering flue gas and then treated, the throughput of the purification adsorption system is obviously increased.
本发明改变现有技术中将不同工况产生的烟气混合之后再一起通过活性炭吸附塔处理的传统技术，将不同工况产生的烟气通过独立的活性炭吸附单元或单元组进行吸附处理，根据各个不同工况产生烟气的特点，适应性的使用不同的吸附处理方案， 既能高效处理各个工序产生的烟气，使得处理完的烟气完全达到规定的排放标准，又能采用最经济性的技术方案实现烟气处理，处理效率高，节约成本。The invention changes the conventional technology in the prior art that the flue gas generated by different working conditions is mixed and then processed together by the activated carbon adsorption tower, and the flue gas generated by different working conditions is adsorbed by the independent activated carbon adsorption unit or the unit group, according to The characteristics of the flue gas produced by different working conditions, the adaptive use of different adsorption treatment schemes, can not only effectively treat the flue gas generated by each process, so that the treated flue gas can fully meet the specified emission standards, and the most economical efficiency can be adopted. The technical solution realizes flue gas treatment, which has high processing efficiency and cost saving.
由于烟气是由多种不同工况产生的，因此，各种烟气的成分、温度等均不相同；如果将各种不同工况产生的烟气直接合并处理，将大大增加吸附塔的处理负荷，浪费资源。本发明的净化处理系统中，集成塔包括多个活性炭吸附单元或单元组，每一处工况产生的烟气通过一个或多个独立的活性炭吸附单元或单元组进行处理，根据每一处工况产生烟气的特点，选择和调整处理该工况烟气的活性炭吸附单元或单元组的工艺条件，选择最适合的吸附环境，提高整个吸附工序的效率。例如：根据烟气中污染物的成分种类、各种成分的含量、烟气的温度等具体实际情况，调整处理该烟气的活性炭吸附单元或单元组中的活性炭停留时间(通过控制活性炭的进料速度和排料速度实现)、吸附处理温度(通过控制原烟气的进气温度、保温装置等实现)等等，使得每一处工况产生的烟气都采用最实惠、最有效的吸附处理方式进行污染物的脱除，提高处理效率，降低处理成本。Since the flue gas is produced by a variety of different working conditions, the composition and temperature of various flue gases are different; if the flue gases generated by various working conditions are directly combined, the treatment of the adsorption tower will be greatly increased.
