AI Technical Summary
Existing batch reactors are prone to leaving residue at the bottom during discharge, making it impossible to completely empty them, and volatile vapors are not effectively captured, resulting in the waste of high-value-added materials.
The system adopts a top discharge design, using a discharge pipe to guide the material flow into the filter basket for filtration. The filtrate is returned to the reactor body, and after being intercepted by the filter basket, it is introduced into the filter tank. The filtrate is then discharged through the external discharge valve. At the same time, volatile vapors are liquefied through a deep cold trap, and unliquefied gases are discharged to avoid residue and waste.
It achieves complete removal of material flow from the reactor, reduces residue, improves cleanliness, and avoids loss of high-value-added materials by capturing volatile vapors through cryogenics.

Abstract
Description
Technical Field
[0001] This utility model specifically relates to an intermittent reactor with top discharge, belonging to the field of reactor technology. Background Technology
[0002] Ruthenium trichloride is generally produced using batch reactors. Batch reactors operate on a single-feed and single-discharge basis. During the reaction, the raw materials inside the reactor are temperature-controlled and stirred to achieve the synthesis of ruthenium trichloride. Existing batch reactors, such as the batch reactor stirring device disclosed in Chinese Patent Publication No. CN221619436U, include a reactor body with a jet pipe rotatably connected inside the reactor body. Five sets of stirring rods are sleeved on the outside of the jet pipe, and jet holes are installed at the bottom of the reactor body. This type of batch reactor stirring device can disperse concentrated materials, enabling the device to fully mix the materials in a short time and improve mixing efficiency. However, most existing batch reactors use bottom discharge, and due to the valve settings, residue is easily left at the bottom of the reactor, making it impossible to completely discharge the material. Utility Model Content
[0003] To address the aforementioned issues, this invention proposes a top-discharge intermittent reactor, which can completely discharge the reaction-generated material stream within the reactor, ensuring more thorough discharge.
[0004] The top-discharge batch reactor of this utility model includes:
[0005] The vessel body has a lid sealed and fixed to the top, and a heating jacket is provided on the outside of the vessel body. A stirring motor for driving the stirring paddle to rotate is fixed on the lid. A feeding gate valve and a discharge port are also provided on the lid. A discharge pipe is connected to the inside of the discharge port, and the bottom of the discharge pipe extends to the bottom of the vessel body, with a safety gap between it and the stirring paddle.
[0006] The top discharge unit includes a filter tank supported and fixed to the top of the vessel body by a bracket, and a feed flange is installed on the top of the filter tank; a filter basket is provided inside the filter tank, and the filter basket is in contact with the inner wall of the filter tank; the bottom of the filter tank is connected to the inside of the vessel body through a return valve; and the discharge port is connected to the feed flange through a discharge valve and a discharge pump.
[0007] During production, the material to be reacted is fed into the reactor through the feeding gate valve. Then, the stirring motor is activated, the stirring paddle rotates and stirs, and the heating jacket is controlled to maintain a constant temperature. After the material has completed the stirring reaction and generated the target material, the stirring paddle stops, and the heating jacket is kept warm. Next, the discharge pump is activated, and the material inside the reactor is discharged through the discharge pipe and sent to the top of the inner side of the filter tank. The material enters the filter tank and is filtered through the filter basket. The filter basket traps and collects the target product, and the filtrate is sent back into the reactor through the return valve. The filtrate can guide the remaining target product in the reactor into the filter tank. After the set time for discharge, the return valve is closed, and the filtrate no longer enters the reactor and is collected inside the filter tank. Finally, after the filter basket has drained, it is removed, and the collection of the target product is completed.
[0008] Furthermore, a sealing ring is provided on the outer side of the top of the filter basket, and a handle is fixed in the middle of the filter basket; a support foot is provided at the bottom of the filter basket; the support foot can support the filter basket, so that the filtrate can be smoothly collected at the bottom of the filter tank. After the material flow is intercepted, the filter basket can be lifted by the handle to achieve top discharge.
[0009] Furthermore, a heat exchanger is connected in series between the feed flange and the discharge pump, and the cold medium circulation end of the heat exchanger is connected to the compression refrigeration equipment. The compression refrigeration equipment works with the heat exchanger to realize the continuous circulation of the cold medium inside the heat exchanger. After the material flow completes the reaction, the material flow is sent to the feed flange through the discharge pump. During the flow of the material flow, it is cooled by the heat exchanger to enhance the precipitation of crystals in the material flow, and is collected by the filter basket to complete the top discharge.
[0010] Furthermore, a tee is connected in series between the discharge port and the discharge valve, and the third end of the tee is connected to the cryogenic trap; an exhaust pipe is provided on the cryogenic trap; a liquid outlet bottom valve is provided at the bottom of the cryogenic trap; during the reaction process, the generated volatile vapor (RuO4) enters the inner side of the jacketed tank through the tee, and is cryogenically cooled by the cryogenic trap. The liquefied liquid is intermittently discharged through the liquid outlet bottom valve, and the unliquefied gas is discharged through the exhaust pipe.
[0011] Furthermore, the deep cold trap includes a sealed jacketed tank, with the tee and exhaust pipe connected between the jackets of the jacketed tank. A cold medium circulation flange is provided on the inner side of the inner liner of the jacketed tank, and the cold medium circulation flange is connected to a compression refrigeration device. During the reaction process, the generated volatile vapor (RuO4) is sent into the inner jacket of the jacketed tank through the tee. Then, the vapor comes into contact with the cold medium on the inner side of the jacketed tank, thereby liquefying the vapor. The liquefied cold liquid is discharged through the bottom outlet valve. The compression refrigeration device works in conjunction with the inner liner to realize the circulation of the cold medium inside the inner liner.
[0012] Furthermore, the bottom of the filter tank is also connected to an external discharge valve; the collected filtrate inside the filter tank can be discharged through the external discharge valve, and the discharged filtrate can be treated a second time and then fed back into the reactor as a new feed stream for the next generation reaction.
[0013] Compared with existing technologies, the top-discharge intermittent reactor of this invention utilizes a discharge pipe extending to the bottom of the reactor body. A discharge pump guides the reaction-generated material flow into a filter basket, where the generated crystals are trapped. The filtrate is then reintroduced into the reactor body, and the remaining material flow within the reactor body is lifted and reintroduced into the filter basket using the filtrate. Finally, all the filtrate in the reactor body is sent to a filter tank, and then discharged through an external drain valve, yielding ruthenium trichloride. This process completely removes the reaction-generated material flow, achieving thorough emptying of the reactor body and reducing residue. Furthermore, due to the absence of a complex bottom valve structure, the reactor bottom has a smooth and flat inner wall, making cleaning easier and more thorough. Additionally, the volatile vapors (RuO4) generated during the reaction process can be captured through cryogenic capture, preventing the overflow and waste of high-value-added products.
