Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically to a rapid overflow device for a reaction vessel. Background Technology

[0002] In many industrial production fields such as chemical and pharmaceutical manufacturing, reaction vessels serve as key equipment, undertaking important chemical reactions or material handling tasks. During the operation of a reaction vessel, as reactants are continuously added and the reaction proceeds, the liquid level inside the vessel gradually rises. When the liquid level exceeds a certain limit, it may not only affect the normal operation of the reaction vessel but also pose safety risks, such as material spillage causing environmental pollution, equipment damage, or even safety accidents.

[0003] In existing technologies, the discharge method of reactors is usually relatively simple, mainly relying on the bottom discharge valve to discharge materials by gravity. The discharge speed is limited by the pipe diameter and liquid level, and the emptying time is long, making it difficult to cope with sudden liquid level rises or emergency shutdowns. This leads to the liquid level in the reactor rising too quickly, increasing safety risks. In order to speed up the discharge, pumps or compressed air are used to drive the discharge, which consumes a lot of energy and has a high risk of failure.

[0004] Therefore, how to provide a rapid overflow device for reactors that can significantly accelerate discharge speed and improve response speed without external power is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a rapid overflow device for a reaction vessel, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid overflow device for a reaction vessel, comprising:

[0008] The reactor has a bottom connected to a collection tank via a discharge pipe, and an overflow port is provided on its side wall.

[0009] A siphon is arranged on the side of the reactor away from the overflow port. One end of the siphon extends to the bottom of the reactor, and the other end is connected to the collection tank. A U-shaped tube is formed on the siphon outside the reactor. The height of the first end of the U-shaped tube near the reactor is higher than the overflow port, and the height of its second end away from the reactor is lower than the overflow port, thus creating a liquid level difference driving condition.

[0010] A liquid-sealed water injection pipe is connected to the U-shaped pipe body. Water is injected into the U-shaped pipe body to form a liquid seal and maintain the siphon effect. When the liquid level in the reactor exceeds the height of the overflow port, it is discharged to the collection tank through the overflow port, which at the same time triggers the siphon effect of the siphon pipe to accelerate the discharge.

[0011] Through the above technical solution, this utility model provides a rapid overflow device for a reactor. It utilizes the height difference between the two ends of the U-shaped tube to create a liquid level difference driving condition. When the liquid level exceeds the overflow port, a siphon effect is triggered, significantly increasing the discharge speed. When the liquid level reaches the overflow port height, discharge is prioritized through the overflow port. As the liquid level rises further, the siphon effect is activated in tandem, achieving accelerated discharge through dual channels (overflow port and siphon pipe), reducing the risk of liquid level runaway. Compared to the traditional single overflow port discharge method, this improves discharge speed and efficiency. Simultaneously, relying on the liquid level difference and siphon effect, no additional power is required, resulting in energy saving and high efficiency. The liquid seal injection pipe injects water into the U-shaped tube to form a liquid seal, effectively maintaining the continuous occurrence of the siphon effect and preventing siphon failure due to liquid interruption or air bubble entry, ensuring the stability and continuity of the discharge process and improving the reliability of the device operation.

[0012] Preferably, the above-mentioned rapid overflow device for a reactor further includes a control unit and a valve control assembly electrically connected to the control unit; the valve control assembly includes a bottom valve, an emergency discharge valve, and a water injection valve; the bottom valve and the emergency discharge valve are installed sequentially from top to bottom on the discharge pipe; the water injection valve is installed on the liquid-sealed water injection pipe. The configuration of the control unit and its valve control assembly enables automated control of the bottom valve on the discharge pipe, the emergency discharge valve, and the water injection valve on the liquid-sealed water injection pipe. The control unit can precisely control the opening and closing of each valve according to the actual operating conditions of the reactor, improving the automation level of the discharge process and the accuracy and timeliness of operation, reducing manual intervention, lowering the risk of human error, and enhancing the safety and stability of the device operation.

[0013] Preferably, in the above-mentioned rapid overflow device for a reactor, a discharge pipe is connected to the discharge pipe located between the bottom valve and the emergency discharge valve, and a discharge valve is installed on the discharge pipe; the discharge valve is electrically connected to the control unit. The discharge pipe and discharge valve are arranged between the bottom valve and the emergency discharge valve for normal production discharge, separated from the emergency discharge path; and are electrically connected to the control unit. This allows for flexible control of the discharge during reactor discharge according to actual production needs, meeting the precise requirements of different processes for discharge volume and time, improving production flexibility, and ensuring stable product quality.

[0014] Preferably, the above-mentioned rapid overflow device for a reactor further includes a level gauge and a thermometer installed on the reactor, wherein the level gauge and the thermometer are electrically connected to the control unit. The level gauge can monitor the liquid level in the reactor in real time and feed the level signal back to the control unit. The control unit automatically adjusts the operation of the control valve assembly and the discharge valve according to the set liquid level range to achieve precise control of the liquid level in the reactor. The control unit can also monitor the temperature change of the liquid in the reactor in real time. Once the temperature exceeds the normal range, the control unit can issue an alarm or automatically take corresponding safety measures, such as closing the feed valve or turning on the cooling system, to prevent problems such as liquid boiling or accelerated evaporation caused by excessive temperature, leading to uncontrolled liquid level or abnormal chemical reaction.

[0015] Preferably, in the above-mentioned rapid overflow device for a reactor, an overflow pipe is connected between the overflow port and the collection tank. This allows the overflowed material to flow smoothly and accurately into the collection tank, avoiding material spillage that could cause environmental pollution and resource waste. Simultaneously, it facilitates centralized treatment and recycling of the overflowed material, improving the environmental friendliness and resource utilization rate of the production process.

[0016] Preferably, the above-mentioned rapid overflow device for a reactor further includes an exhaust pipe, the bottom end of which is connected to the overflow pipe, and the top end of which is connected to a waste gas treatment system. When material overflows from the reactor, the waste gas that may be generated can enter the waste gas treatment system through the exhaust pipe, preventing the waste gas from being directly discharged into the atmosphere and reducing environmental pollution; at the same time, it can alleviate pressure fluctuations inside the reactor during overflow and prevent the siphon pipe from interrupting material discharge due to negative pressure.

[0017] Preferably, in the above-mentioned rapid overflow device for a reactor, a feed inlet is provided at the top of the reactor. The feed inlet at the top of the reactor provides a convenient channel for adding materials, allowing operators to add raw materials to the reactor promptly and accurately according to production needs, ensuring a sufficient supply of reactants, guaranteeing the smooth progress of the reaction process, and improving production efficiency.

[0018] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a rapid overflow device for a reaction vessel, which has the following beneficial effects:

[0019] 1. This utility model utilizes the liquid level difference driving condition of the U-shaped tube body to prioritize material discharge through the overflow port when the liquid level exceeds the overflow port; when the liquid level rises further, the siphon effect is activated, forming a dual channel (overflow port + siphon tube) to accelerate material discharge; compared with traditional single gravity discharge, the emptying time is shortened to meet the needs of emergency working conditions and improve safety performance.

[0020] 2. The liquid seal water injection pipe of this utility model forms a closed liquid seal by injecting water, avoiding gas interference and ensuring continuous and efficient operation of the siphon effect.

[0021] 3. The liquid level gauge and thermometer of this utility model collect data in real time and feed the signal back to the control unit. The control unit controls the opening and closing of the corresponding valve body, thereby improving the response time.

[0022] 4. This utility model relies on the liquid level difference to drive the siphon effect, eliminating the need for external energy sources such as pumps and compressors, thus reducing energy consumption and equipment costs. It can also be improved on existing structures, making it convenient and quick. Attached Figure Description
