Description

Technical Field

[0001] The utility model belongs to the technical field of chemical reaction auxiliary devices, in particular to a solid-liquid reaction gas generating device. Background Art

[0002] As a common and important type of chemical reaction, solid-liquid phase reaction has a wide range of applications in various fields. In this type of reaction, the contact surface between solid and liquid is the key, because the reaction usually occurs at this interface. The ratio of liquid to solid on this contact surface directly determines the progress of the reaction. In this process, by controlling the ratio of liquid to solid, the reaction rate and the amount of product generated can be precisely controlled. For example, in some reactions, too much liquid may lead to too fast a reaction rate and reduced product selectivity, while too little liquid may limit the progress of the reaction. A variety of gases can be generated through chemical reactions between solids and liquids, covering hydrogen, carbon dioxide, oxygen, ammonia, hydrogen sulfide, nitric oxide, nitrogen dioxide, chlorine dioxide, chlorine, sulfur dioxide and other gases. These gases not only have important applications in industrial production, but also play a key role in environmental protection, disinfection, and energy fields. Therefore, the research and application of solid-liquid phase reactions are of great significance for promoting the development of industrial production, solving environmental problems, and improving energy efficiency. By deeply understanding the effect of the liquid-to-solid ratio on the reaction, the reaction conditions can be optimized and the reaction efficiency can be improved, thus bringing more opportunities and possibilities for the development of various fields. Controlling the flow rate and flow rate of liquid addition is crucial to adjusting the solid-liquid ratio. By changing the flow rate and flow rate, the contact time and contact area of ​​the liquid on the solid surface can be controlled to a certain extent, thereby affecting the rate and efficiency of the reaction. For example, when the reaction rate is slow, the flow rate and flow rate can be increased to increase the contact frequency between the liquid and the solid and speed up the reaction. On the contrary, when the reaction rate is too fast, the flow rate and flow rate can be reduced to prevent over-reaction or product loss.

[0003] Currently, commonly used liquid flow rate and flow control devices mainly rely on electric transmission devices, such as peristaltic pumps. Although these devices can provide precise fluid control and stable transmission when dealing with lower flow rates and flows, they are expensive because they require sophisticated engineering design and high-performance materials. This high cost limits the widespread use of these devices in laboratories and industrial production. In laboratory environments, researchers may face challenges with limited budgets, which may lead to the selection of lower-cost alternatives. However, these alternatives often sacrifice accuracy and stability, which may lead to uncertainty in experimental results and even affect the accuracy and repeatability of research. In industrial production, cost constraints may affect the competitiveness and profitability of enterprises. Especially for small or new businesses, investing in high-cost liquid flow control devices may become a considerable burden. This may limit their investment in technological innovation and product development, affecting the development and growth of the enterprise.

[0004] Therefore, it is of great significance to design a new solid-liquid reaction gas generating device to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a solid-liquid reaction gas generating device which solves the problem that the high cost of current liquid flow rate and flow control devices limits their application in laboratories and industrial production.

[0015] In the above technical solution, preferably, a fan for controlling the outward diffusion flow of the gas generated by the reaction is provided at the diffusion port.

[0016] Advantages and effects

[0017] 1. Low cost: The device does not need to rely on electric transmission devices, so the cost is low. Compared with traditional liquid flow rate and flow control devices, the array porous drip device does not require expensive engineering design and high-performance materials, thereby reducing costs and making it easier to be widely used in laboratories and production sites.

[0018] 2. Simple operation and controllability: Using the end hole diameter of the dropper and the liquid level to control the liquid addition rate makes the operation very simple and easy to control. Researchers or operators only need to adjust the liquid level of the dropper or replace the dropper with different hole diameters to achieve different liquid addition rates to meet the needs under different reaction conditions.

[0019] 3. Stable solid-liquid reaction: Since the liquid drips evenly into the solid bed through multiple apertures, the contact between the liquid and the solid is more uniform and stable. This helps to maintain the stability of the reaction system, reduce product changes or side reactions caused by uneven reactions, and thus improve the controllability and efficiency of the reaction.

[0020] 4. Small size and flexible application: The array multi-hole drip device is small and can be easily placed on a laboratory table or in a small space at the production site. This makes it suitable for laboratories and production lines of various sizes, and can achieve solid-liquid reactions in limited spaces, providing more flexibility and options for laboratory research and industrial production.

[0021] 5. High gas generation efficiency: For some gases that are easily soluble in water, the gas generated after solid-liquid mixing dissolves in water, which reduces the gas preparation rate. This device controls the flow rate of the liquid and then controls the solid-liquid ratio in the solid-liquid reaction, thereby achieving immediate release of the gas after generation, reducing the dissolution of the gas, and thus improving the gas preparation efficiency.

[0022] In summary, the array porous drip-type solid-liquid reaction gas generation device has many advantages such as low cost, simple operation, stable reaction effect and flexible application scenarios, which will bring more convenience and possibilities to laboratory research and industrial production in the field of chemistry.

[0023] In addition to the advantages mentioned above, this device can also further expand its application in teaching and scientific research. First, as a low-cost and easy-to-operate experimental device, the array multi-hole drip-type solid-liquid reaction gas generation device is very suitable for teaching chemical experiments in teaching laboratories. Students can intuitively understand the basic principles of solid-liquid reactions and experimental operation techniques by operating the device, thereby improving their experimental skills and chemical understanding.

[0024] In addition, the array porous drip-type solid-liquid reaction gas generation device is also a very valuable tool for scientific researchers. Due to its stable reaction effect and controllable operating characteristics, researchers can use this device to conduct various types of solid-liquid phase reaction research. Whether it is used to explore new reaction conditions, optimize reaction parameters, or develop new synthesis methods and prepare new materials, it can provide researchers with a reliable experimental platform and experimental data, thereby promoting the progress of scientific research.

[0025] Therefore, this solid-liquid reaction gas generation device is not only of great significance in laboratory teaching, but also plays an irreplaceable role in the field of scientific research. Its low cost, simple operation, stable and reliable characteristics, as well as flexible application scenarios, will bring more convenience and possibilities to teaching and scientific research in the field of chemistry, and promote the development and progress of chemical science.
