Definitions

  • the utility model belongs to the technical field of chemical equipment, and specifically relates to a fluidized bed catalyst supplement device.
  • a fluidized bed reactor is a reactor that uses fluid to pass through a granular solid layer to make solid particles in a suspended motion state and react. Since the fluidized bed reactor can use fine powder particles and contact the fluid in a suspended state, the fluid-solid phase boundary area is large, which is conducive to the progress of the heterogeneous reaction and improves the utilization rate of the catalyst. In addition, due to the intense mixing of particles in the bed, the fluidized bed reactor makes the temperature and concentration of the particles uniform in the whole bed. The heat transfer coefficient between the bed and the inner immersion heat exchange surface is very high. The heat capacity of the whole bed is large. High stability, these are conducive to isothermal operation of strong exothermic reaction.

Because of this, fluidized bed reactors have been widely used in many sectors such as chemical industry, petroleum, metallurgy, and nuclear industry.
  • the fluidized bed reactor also has its inherent shortcomings. Because the catalysts in the bed collide with each other violently in the suspended state, it is easy to cause a large loss of catalyst. Taking the production of a broad-spectrum bactericide chlorothalonil as an example, the preparation of chlorothalonil requires a mixture of isophthalonitrile, chlorine and nitrogen to be passed into a fluidized bed equipped with a special chlorination catalyst for reaction. Since the catalyst in the fluidized bed is always in a fluidized state, the catalyst is ground into tiny particles in the fluidized state. Some of the smaller particles are difficult to be separated by the separator and are carried out of the reaction system with the materials, resulting in catalyst storage. The volume is gradually decreasing, and the production capacity is gradually decreasing. In order to maintain normal production, extend the reaction cycle, and improve economy, it is necessary to add a catalyst to the reaction system.

Description

一种流化床催化剂补加装置 技术领域
本实用新型属于化工设备技术领域，具体地，涉及一种流化床催化剂补加装置。
背景技术
流化床反应器是一种利用流体通过颗粒状固体层而使固体颗粒处于悬浮运动状态并进行反应的反应器。流化床反应器由于可采用细粉颗粒，并在悬浮状态下与流体接触，流固相界面积大，有利于非均相反应的进行，提高了催化剂的利用率。此外，流化床反应器由于颗粒在床内混合激烈，使颗粒在全床内的温度和浓度均匀一致，床层与内浸换热表面间的传热系数很高，全床热容量大，热稳定性高，这些都有利于强放热反应的等温操作。不仅如此，流化床内的颗粒群有类似流体的性质，可以大量地从装置中移出、引入，并可以在两个流化床之间大量循环，使得一些反应-再生、吸热-放热、正反应-逆反应等反应耦合过程和反应-分离耦合过程得以实现，也使得一些易失活催化剂能够工程应用。正因为如此，目前流化床反应器已在化工、石油、冶金、核工业等诸多部门得到了广泛应用。
然而，流化床反应器也有其固有的缺点，由于床内催化剂在悬浮状态下相互之间剧烈碰撞，容易造成较大的催化剂损失。以一种广谱杀菌剂百菌清的生产为例，百菌清的制备需要将间苯二甲腈、氯气和氮气的混合气通入装有专用氯化催化剂的流化床中进行反应。由于流化床中的催化剂始终处于流化态，催化剂在流化态状况下被研磨成微小颗粒，有一部分较小的颗粒难以被分离器分离出来而随着物料带出反应系统，导致催化剂藏量逐渐降低，生产能力逐渐下降。为了维持正常生产的进行，延长反应周期，提高经济性，需要向反应系统内补加催化剂。
实用新型内容
为了克服现有技术的不足，本实用新型提供一种流化床催化剂补加装置。
技术方案：本实用新型提供了一种流化床催化剂补加装置，设于流化床体侧壁，包括储料罐、电机、搅拌桨、落料管、输料管；储料罐为横置圆柱形罐体；搅拌桨横置于储料罐内，搅拌桨的旋转轴设于储料罐的中轴线上；电机设于储料罐外，与搅拌桨动力连接；落料管竖直设于储料罐的底部，并与储料罐内部连通；落料管上设有能够打开和闭合的落料阀；输料管设于落料管的下端，并将落料管与流化床内部连通。当需要向流化床内补加催化剂时，将需要补加的催化剂从顶部装料口装入储料罐，由电机带动搅拌桨缓慢搅拌，然后打开落料阀，催化剂颗粒经落料管进入输料管，最终进入流化床内。
进一步地，上述的流化床催化剂补加装置，电机和搅拌桨之间由皮带和皮带轮动力连接；皮带和皮带轮外还套设有保护壳。皮带轮组件具有经济可靠等特点，套设有保护壳可提高运行的可靠性，同时也能够避免发生意外。
进一步地，上述的流化床催化剂补加装置，储料罐的中轴线与水平方向的夹角为a，a的范围为2～7°。
进一步地，上述的流化床催化剂补加装置，落料管设于储料罐底部位置相对较低的一端，便于顺利充分出料。
进一步地，上述的流化床催化剂补加装置，储料罐上还设有活化气入口和活化气出口，活化气入口设于储料罐侧壁底部，活化气出口设于储料罐顶部。设置活化气入口和活化气出口具有两方面的作用。第一，有些催化剂在使用前需要进行高温活化才能达到其应有的活性，通过以上设置可以方便地将活化气引入储料罐内，经过长时间循环逐渐升温活化，达到使用要求后再送入流化床内。第二，流化床内温度较高，如果直接将催化剂送入流化床，温度急剧变化容易导致催化剂崩裂，通过以上设置可以方便地通入活化气，活化气在循环过程中逐渐升温，将催化剂缓慢加热至与流化床内的温度相同，然后再送入流化床。
进一步地，上述的流化床催化剂补加装置，活化气入口和活化气出口处均设有颗粒物过滤罩。
进一步地，上述的流化床催化剂补加装置，储料罐外部还包裹有隔热层；隔热层的材料优选岩棉、石棉、玻璃纤维等隔热材料。
优选地，上述的流化床催化剂补加装置，输料管斜向下设置，与水平方向的夹角为b，b的范围为12-30°，便于催化剂顺利进入流化床内，并且能够减轻催化剂在进料过程中的磨损。
进一步地，上述的流化床催化剂补加装置，输料管由下至上依次包括出料段、落料段、扩散段、收缩段、进气部和载气接口；落料管与落料段连接。将高温高压的载气从载气接口通入进气部，优选使用氮气，然后，载气依次流经收缩段和扩散段后形成流态比较稳定的在气流，流经落料段时与从落料管内下落的催化剂相遇，最终与催化剂一起流经出料段并进入流化床内。为了加强保护和减少热损失，也可在落料管和输料管包裹隔热材料。
进一步地，上述的流化床催化剂补加装置，还包括一组温度传感器和控制箱；控制箱内设有单片机；温度传感器设于流化床体侧壁，并与控制箱电性连接；落料阀为电磁阀，与控制箱电性连接；载气接口处设有载气控制阀，载气控制阀为电磁阀，并与控制箱电性连接。通过以上设置，可以进一步提高自动化程度。由于催化剂的效能会直接影响流化床内的 温度，当温度传感器检测到流化床内的温度偏离正常工作状态时，控制箱控制载气控制阀和落料阀打开，将储料罐内的催化剂送入流化床内，经过一定的时间，催化剂补加完成，落料阀和载气控制阀，完成一次补加作业。
有益效果：本实用新型提供的流化床催化剂补加装置，结构紧凑，使用安全，性能可靠，能够方便地实现向流化床内补加催化剂，能够完成催化剂使用前的活化操作，还能够有效防止催化剂因温度剧烈变化而出现崩裂，而且还具有简单的自动化功能。
