Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide production technology, specifically to a fungicide production device with an online catalyst loading system. Background Technology
[0002] Chlorothalonil is a highly effective, low-toxicity, broad-spectrum fungicide. It interacts with glyceraldehyde-3-phosphate dehydrogenase in fungal cells, binding to proteins containing cysteine within this enzyme and thus disrupting its activity. This disrupts the metabolism of fungal cells, rendering them inactive and thus preventing fungal diseases in various crops. Chlorothalonil does not have systemic activity, but after being sprayed onto plants, it adheres well to the plant surface and is not easily washed away by rain, resulting in a long-lasting effect.
[0003] In the chlorination process of chlorothalonil, coconut shell activated carbon catalyst is often used in the fluidized bed reactor. The catalyst undergoes fluidization and disturbance in the fluidized bed. Due to the violent turbulence and collisions between catalyst particles, catalyst carbon powder can escape into subsequent systems. At the same time, the activity of the catalyst decreases with the reaction. Therefore, it is necessary to shut down the reactor, unload the catalyst, and reload fresh catalyst. This means that there is no product output during start-up and shutdown, and catalyst replenishment is required. Existing catalyst replenishment devices require a motor to drive an agitator to feed the catalyst into a feed pipe, and then use hot carrier gas to send the catalyst from the feed pipe into the fluidized bed. The inlet of the pipe entering the fluidized bed reactor wall needs to be at a certain angle to the horizontal. Only small batches can be added gradually. Moreover, the airtightness of the equipment cannot be guaranteed when transporting materials. The stability of the equipment is low at high temperatures, which can easily lead to safety accidents.

[0041] Working principle:
[0042] (1) Drying and activation of fresh catalyst
[0043] Open the gas phase pipeline to cut off the first gas phase pipeline shut-off valve 104, add sufficient fresh catalyst to the new catalyst drying and activation tank 1, exceeding the amount of catalyst to be replenished, to ensure multiple catalyst replenishments, and close the catalyst feed shut-off valve 109; open the first high-temperature gas feed shut-off valve 108 to inject high-temperature nitrogen into the new catalyst drying and activation tank 1 to dry the new catalyst, and at the same time turn on the first equipment cylinder electric heating belt 105, set the temperature, during the drying process, the nitrogen and moisture in the catalyst pass through the first cyclone separator 101 and then through the pulse dust collector 6 before going to the alkaline tail gas absorption; when the first thermometer 107 on the new catalyst drying and activation tank 1 reaches the set temperature, the drying of the fresh catalyst is completed. After the catalyst is dried, the catalyst is activated. The second high-temperature gas feed shut-off valve 110 is opened to inject high-temperature chlorine gas into the new catalyst drying and activation tank 1 to activate the dried catalyst. The activation temperature is 200-250℃. The activation temperature is observed through the first thermometer 107. The activation is completed after the activation temperature is reached and maintained for 12 hours. The catalyst pretreatment process is completed. The second high-temperature gas feed shut-off valve 110 is closed. After waiting for 2 hours, the first high-temperature gas feed shut-off valve 108 is closed.
[0044] (2) Loading of fluidized bed catalyst
[0045] First, confirm the specific weight of the catalyst to be added (assuming it is 50kg). Input the specific weight value into the PLC sequential control module, which is controlled by the first weighing module 201 on the catalyst replenishment tank 2. Input the set value of 50kg, and after starting the PLC sequential control module on the catalyst replenishment tank 2, the sequential control actions are as follows: Close the first gas phase pipe shut-off valve 104, open the first high-temperature gas feed shut-off valve 108, and close the first high-temperature gas feed shut-off valve 108 after the system is pressurized to 400kPa; confirm that the second discharge pipe shut-off valve 202 and the third discharge pipe shut-off valve 203 are closed, open the first discharge pipe shut-off valve 103, close the first discharge pipe shut-off valve 103 after the weighing module displays 50kg, start the second equipment cylinder electric heating belt 205, set the temperature to 200~250℃, and the catalyst metering is completed. Open the third high-temperature gas feed shut-off valve 208 to pressurize the catalyst replenishment tank 2. After the pressure gauge displays 400 kPa, close the third high-temperature gas feed shut-off valve 208 and open the second feed pipe shut-off valve 202 and the third feed pipe shut-off valve 203. The system replenishes the catalyst to the fluidized bed reactor 3. At this time, the system will determine whether to open the third high-temperature gas feed shut-off valve 208 based on the pressure gauge display on the catalyst replenishment tank 2. When the pressure is lower than 350 kPa, open the high-temperature nitrogen valve to continue pressurizing. When the first weighing module 201 displays 0 kg, close the third feed pipe shut-off valve 203 and the second feed pipe shut-off valve 202. Close the third high-temperature gas feed shut-off valve 208, and the entire catalyst replenishment process is completed.
[0046] (3) Unloading of spent catalyst
[0047] First, confirm the specific weight of the catalyst to be unloaded (assuming 50kg). Input the specific weight value into the PLC sequential control module and start the sequential control. At this time, the second weighing module 403 on the waste catalyst unloading tank 4 displays 0kg. Confirm that the fourth feed pipe shut-off valve 401, the fifth feed pipe shut-off valve 402, the fourth high-temperature gas feed shut-off valve 406, the second gas phase pipe shut-off valve 405, and the sixth feed pipe shut-off valve 408 are in the closed state. Open the second gas phase pipe shut-off valve 405 to depressurize the system. The pressure gauge of the waste catalyst unloading tank 4 displays below 50kPa. Open the fourth feed pipe shut-off valve 401 and the fifth feed pipe shut-off valve 402. The catalyst in the fluidized bed reactor 3 is unloaded into the waste catalyst unloading tank 4. When the second weighing module 403 displays 50kg, close the fourth feed pipe shut-off valve 401 and the fifth feed pipe shut-off valve 402. The unloading of the waste catalyst is completed.
[0048] (4) Waste catalyst transportation and cooling
[0049] The catalyst positive pressure sequential control module is activated. The system closes the second gas phase pipe shut-off valve 405 and opens the fourth high-temperature gas feed shut-off valve 406 to pressurize the waste catalyst unloading tank 4. After pressurizing to 400 kPa, the fourth high-temperature gas feed shut-off valve 406 is closed. The first ambient temperature gas feed shut-off valve 407 is opened to purge the conveying pipeline with ambient temperature nitrogen. Then, the sixth discharge pipe shut-off valve 408 is opened to discharge the waste catalyst. The waste catalyst is conveyed to the waste catalyst bulk silo 5 through ambient temperature nitrogen. When the second weighing module 403 displays 0, the waste catalyst has been completely conveyed. The sixth discharge pipe shut-off valve 408 and the first ambient temperature gas feed shut-off valve 407 are closed. The second ambient temperature gas feed shut-off valve 502 is opened to cool the waste catalyst bulk silo 5 with ambient temperature nitrogen.
