DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine for filling spherical, cylindrical or rectangular granules. More specifically, the present invention relates to a filling machine for uniformly filling spherical, cylindrical, or rectangular catalyst particles into reaction tubes of a multitubular vertical reactor. Conventionally, multi-tube vertical reactors have been widely used in all industrial fields, but multi-tube vertical reactors are not often used in the chemical industry, especially when conducting gas phase or liquid phase reactions using catalysts. This is a reactor. The form of this multi-tube vertical reactor varies depending on various reactions or catalysts used, but the external heat exchange type multi-tube vertical reactor will be explained as follows. In this reactor type, a long and narrow reaction tube is filled with a catalyst, and a heat transfer medium outside the tube heats or removes heat through the tube wall to adjust the temperature of the catalyst layer to a range suitable for the reaction. Usually, the reactor consists of a large number of vertical reaction tubes arranged in parallel, in the form of a large shell-and-tube heat exchanger. This external heat exchange type multitubular vertical reactor is used to carry out various reactions in which the optimal reaction temperature range is narrow in exothermic or endothermic reactions, and moreover, a certain amount of contact time is required. When using the above-mentioned type of external heat exchange type multi-tube vertical reactor, various problems arise, among them the problem of the reaction tube diameter and the problem of uniform passage of the raw material gas flowing through the reaction tubes containing the catalyst. That is, the problem of uniformly filling the catalyst into the reaction tube is important. Considering the diameter of the reaction tube from the viewpoint of temperature control, the heat generated during the reaction occurring on the catalyst moves in the radial direction through the catalyst layer and through the tube wall to the heat medium. Therefore, it is preferable that the diameter of the reaction tube is small. However, if the diameter of the reaction tube is small, the number of reaction tubes becomes enormous, and the time and effort required to fill and extract the catalyst also increases, so there is a limit to this. The minimum pipe diameter that can be used industrially is about 15 mm. When filling a reaction tube with a catalyst, the diameter of the reaction tube is taken into consideration from the viewpoint of improving yield and controlling the reaction temperature, and because the tube diameter is small and the tube length is long, some catalyst particles may fall down inside the tube. During the process, they come into contact with each other, and a large number of catalyst particles rush in at once, which tends to cause crosslinking, a phenomenon called bridging, in the reaction tube. This bridging phenomenon causes the catalyst filling state of each reaction tube to be non-uniform, thereby causing the ventilation resistance of each reaction tube to differ. Therefore, in some tubes, the contact time of the reaction gas with the catalyst is too short, resulting in a large amount of unreacted components.
In another tube, the contact time of the reaction gas with the catalyst is too long and many side reactions occur. Such differences in reaction conditions between reaction tubes not only reduce the overall yield, but also accelerate the decline in catalyst activity, and may even prevent endothermic reactions from occurring immediately. Therefore, pay close attention to the filling of catalyst particles into each reaction tube, and fill the catalyst particles so that the catalyst resistance of each reaction tube is the same.
It is necessary to ensure that the reaction gas passes through each reaction tube evenly. In order to evenly fill a large number of reaction tubes with catalyst particles, it is best not to fill the reaction tubes with more than one catalyst particle at a time. However, in such a method, the length of the reaction tube is long and the number of reaction tubes is enormous, so the time and effort required to fill the catalyst particles are immeasurable. Therefore, such a method is not practical. Conventionally, when filling a reaction tube with catalyst particles, it has been carried out manually, using a method that is close to, if not the best method described above, and which requires a huge amount of time and effort. However, in spite of this, the catalyst filling state is often non-uniform. There are many ways to create a filling machine that would require a huge amount of time and effort to achieve a uniform catalyst filling state, but since thousands of reaction tubes are tightly packed in a narrow area, it is difficult to find an effective filling machine. The filling machine has yet to be invented. The inventors conducted extensive research to solve the many difficulties encountered in conventional catalyst filling, discovered a catalyst filling machine that could be used in a short time, and evenly packed the catalyst particles, and completed this invention. did. Therefore, an object of the present invention is to prevent the bridging phenomenon that occurs when filling catalyst particles and to uniformly fill the catalyst particles. Another objective is to shorten the time required for the filling operation, and still another objective is to perform the filling operation mechanically without relying on manual labor. Other objects will become apparent from the detailed description of the invention below. The present invention includes a hopper 1, a funnel 4, and a funnel 4.
In a catalyst filling machine equipped with a conduit 5 connecting a catalyst particle outlet and a reaction tube, a hopper 1 and a funnel 4 are connected.
It consists of a catalyst filling machine characterized in that an electromagnetic feeder 3 consisting of an electromagnetic feeder drive unit 2 and a trough 3 is provided without catalyst in the hopper 1 and funnel 4, and is installed on the upper part of the reactor. The structure allows for free movement. The electromagnetic feeder drive unit 2 used in the present invention is usually commercially available and can be used, and by changing the voltage applied to the electromagnet of the electromagnetic feeder drive unit 2, the catalyst particle feeding speed can be changed. Further, the width of the trough 3 which receives the catalyst particles falling from the hopper 1 and sends them into the funnel 4 while being vibrated can be appropriately changed depending on the shape and particle size of the catalyst. The hopper 1 used in the present invention can receive the required amount of catalyst to be filled into the reaction tube, has an inclination equal to or higher than the angle of repose of the catalyst particles, and is designed to drop the catalyst into the trough 3 of the electromagnetic feeder drive unit 2. An opening is provided at the bottom of the hopper 1. The distance between the outlet of the hopper 1 and the trough 3 is preferably 60 mm or less, preferably within the range of 1 to 60 mm. The funnel 4 used in the present invention receives the catalyst dropped from the trough 3 and sends it into the conduit 5, and is made up of a conical or pyramidal receiving port and a circular pipe to which the conduit is directly connected. Trough 3 and funnel 4
It is appropriate to select a distance within the range of 20 mm or less. The conduit 5 used in the present invention is for guiding catalyst particles from the funnel outlet to the reaction tube, and can be a flexible conduit made of a material such as rubber, vinyl chloride, or polyethylene. When the catalyst packing machine according to the present invention is used to fill catalyst particles into a reactor consisting of several thousand reaction tubes, for example, a reactor in the production of ethylene oxide, phthalic anhydride, maleic anhydride, acrolein, acrylic acid, etc. , the effects of the present invention are extremely large. In other words, whereas conventionally it required a long time of 7 to 30 days and a great deal of labor to fill a reactor made up of several thousand reaction tubes, the catalyst filling machine of the present invention can be used to fill a reactor with catalyst. and 5~
It can be completed in an extremely short time of 120 hours and with little effort. Furthermore, the catalyst filling state after filling is uniform without any unevenness due to bridging, there is no need to adjust the catalyst resistance, and the catalyst activity exhibits a stable value, which is an industrially advantageous effect. In order to describe the present invention in more detail, the present invention will be explained using drawings. At the same time, the usage of the filling machine according to the present invention will be explained using the drawings. However, the drawing is a schematic embodiment of the present invention, and all modifications are included in the present invention as long as they fall within the scope of the claims. The catalyst filling machine of the present invention is installed at the top of the reactor, and the conduit is lowered from the filling port such as a manhole, and the other end of the conduit is connected to the top of each reaction tube, and the required amount of catalyst is loaded into the hopper.
can be injected into. The hoppers 1 are preferably arranged on the same circumference as shown in FIG. 1, but they can also be arranged in one horizontal row or in two rows back to back. The number of hoppers 1 arranged can be increased or decreased depending on the required amount of catalyst, the diameter of the reactor, the required diameter of the filling machine, and the other end, but it is more efficient to increase the number of hoppers 1. The lower part of the hopper 1 has a slope greater than the angle of repose of the catalyst particles, and is further provided with a rectangular opening on a trough 3 having an electromagnetic feeder drive 2, which serves as a catalyst outlet. The catalyst injected into the hopper 1 falls from the outlet of the hopper 1 onto a trough 3 having an electromagnetic feeder drive unit 2, and further, due to the vibration of the electromagnetic feeder drive unit 2,
vibrates, the catalyst moves, and can be dropped into the funnel 4. The filling speed can be changed depending on how the electromagnetic feeder drive unit 2 is vibrated. Mainly it changes the magnitude of the amplitude by adjusting the voltage and
This will change the moving speed, that is, the filling speed. This speed determines how the catalyst is packed in the reaction tube, so careful attention must be paid to it. Furthermore, the groove width of the trough 3 may have to be changed slightly depending on the filling speed, catalyst particle diameter, shape, etc., since catalyst particles may clog or remain on the trough. The catalyst that continuously falls from the trough 3 little by little enters the funnel 4. The funnel 4 has a circular tube at its lower part and is connected to a conduit 5. The diameter of the circular tube is preferably the same as the diameter of the reaction tube, but it does not necessarily have to be the same. The catalyst enters the conduit 5 from the funnel 4, passes through the conduit 5, and enters the reaction tube.The conduit 5 is preferably made of a flexible material that can be bent freely so that it can be filled into the reaction tubes at all positions in the reactor. It is also desirable to have a connection type that allows for easy removal. The number of combinations of the hopper 1, electromagnetic feeder drive unit 2, funnel 4, and conduit 5 to be installed in the catalyst filling machine varies depending on the required amount of catalyst, reactor diameter, permitted filling machine diameter, etc. In consideration of workability and efficiency, it is preferable to design the reaction tube so that it can be filled into several or several dozen reaction tubes at once. They can be arranged on the same circumference as shown in Figure 1.
You can arrange them in one row horizontally or in two rows back to back. The present invention will be explained in more detail with reference to Examples below. However, the present invention is not limited to this embodiment unless it goes against the spirit thereof. Example 1 In order to fill a multi-tube vertical reactor with 3800 reaction tubes with an inner diameter of 30 mm and a length of 12 m, cylindrical catalyst particles with a diameter of 6.4 mm and a length of 6.4 mm were prepared. A catalyst filling machine was designed and manufactured using the model shown in the figure. A trough 3 with an electromagnetic feeder drive unit 2 attached;
200V, 50Hz, trough width 60mm 32 pieces Hopper: 32 pieces on a circumference of 1600mm outer circumference Conduit: Vinyl pipe with inner diameter 30mm Between hopper 1 and trough 3 = 5mm Between trough 3 and funnel 4 = 5mm 32 hoppers 1. 7000 ml of catalyst particles were added to each. The electromagnetic feeder drive unit 2 was driven to apply vibration to the trough 3, and the catalyst particles were transferred little by little from the outlet of the hopper 1 onto the trough 3, and were gradually moved on the trough 3. The catalyst particles were dropped from the trough 3 into the funnel 4, and then passed through a vinyl conduit 5 with an inner diameter of 30 mm and filled into the reaction tube. It took 7 minutes to fill 7000ml of catalyst into one reaction tube. It took about 24 hours to fill all 3,800 reaction tubes with catalyst. Example 2 In Example 1, using one reaction tube of the catalyst filling machine, 8500 g of the same catalyst as in Example 1 was charged at a rate of 1000 g, the entire amount of catalyst was put into the hopper, and the same reaction tube as in Example 1 was used. The catalyst was charged in the same manner.
It took 8 minutes and 30 seconds to fill the entire amount of catalyst. After starting the catalyst filling, for 1 to 2 minutes, for 4 to 5 minutes, and for 7 minutes.
The catalyst loading weight was measured for each minute between ~8 minutes. The results are shown in Table-1. Comparative Example 1 A catalyst was filled in the same manner as in Example 2 except that the electromagnetic feeder drive unit 2 was provided in the hopper 1 and the funnel 4 was connected to the hopper 1.
It took 8 minutes and 30 seconds to fill the entire amount of catalyst. After starting the catalyst filling, for 1 to 2 minutes, for 4 to 5 minutes, and for 7 minutes.
The catalyst loading weight was measured for each minute between ~8 minutes. The results are shown in Table-1. 【table】
