GY-ZDCY-12S multifunctional nitrogen blowing device manufacturer

Beijing purified water equipment nitrogen blower, multiple anti-corrosion nitrogen blowers, fully automatic nitrogen concentration device

Product Introduction
The nitrogen blowing instrument uses inert gas to blow the heated sample solution, rapidly concentrating the sample to be processed and achieving the effect of rapid separation and purification. The method is easy to operate, especially when processing multiple samples simultaneously, greatly reducing the detection time. Used to remove small amounts of volatile liquids such as water and some organic solvents, it is commonly used in laboratories. Especially in situations where the use of a rotary evaporator is not safe enough (solvents may boil violently), it is more ideal to switch to a nitrogen blowing instrument. The Shanghai Guiyong fully automatic nitrogen blowing instrument has effectively solved these problems by integrating and optimizing existing technological advantages. The device adopts the * concentration method to significantly improve the concentration rate. At the same time, the equipment uses its own exhaust fan to directionally discharge the evaporated exhaust gas through the exhaust pipe, allowing the nitrogen blowing concentration device, which originally had to be placed in a ventilated kitchen, to be safely installed on a general experimental platform. Not only is it easy to move, saving laboratory costs, but it also minimizes the harm of toxic and harmful solvents to operators. It is a sample pretreatment device in the laboratory.

Advantages of fully automatic nitrogen blower
The fully automatic nitrogen blowing instrument GY-ZDCY-12S can automatically concentrate a single or multiple 12 samples simultaneously without the need for manual monitoringFully automatic nitrogen concentratorMultiple optical sensors are used to detect the concentration process of each sample. When the evaporation concentration reaches the preset volume, the system automatically stops the nitrogen purging of the corresponding channel and gives an alarm prompt. The entire concentration process does not require manual supervision;

The purpose of nitrogen blower:
Used to remove small amounts of volatile liquids such as water and some organic solvents, it is commonly used in laboratories. The typical application of a nitrogen blower is in solid-phase extraction gas chromatography detection. After solid-phase extraction is completed, the nitrogen blower can be used to blow off most of the solution in the eluent, completing a concentration process, and then the sample can be injected into the machine for detection.GY-ZDCY-12S multifunctional nitrogen blowing device manufacturer

Good matching, mutually beneficial cycle, keeps the two systems running reliably and stably. On Earth, the freshwater available for human use is 2.5%, with the remaining 97.5% being seawater or saltwater, and the majority being severely lacking in water. Water, as the source of life, is very important, and how to solve water resource problems has become a major challenge for the region. Before the new seawater desalination technology is announced. In modern industrial production, a large amount of water resources are needed. Open source and throttling are ways to solve water scarcity. Although many modern enterprises install water circulation systems, they can only alleviate the situation of water scarcity and cannot reduce water waste. Friends with knowledge of physics must be aware that extracting fresh water from the sea through distillation methods is time-consuming and labor-intensive, with limited freshwater production, and cannot be carried out on a large scale. Scientists have made other attempts based on this, but have not yet developed efficient methods. Australian Chinese scientists have used graphene technology to produce a graphene filtration membrane, which is crystal clear and as thin as a cicada's wing. Such an inconspicuous small piece of paper can actually filter polluted seawater from above in one go, achieving the standard of freshwater conversion for drinking water. This technology is not uncommon. Several years ago, scientists completed experiments, but due to the high manufacturing cost of graphene films at that time, it was obviously unrealistic to achieve large-scale seawater desalination. Australian Chinese scientists have developed graphene films, using common soybean oil as raw material. The films produced retain the characteristics of graphene films and have low production costs.
Why can graphene filter film achieve seawater desalination? The micro nano channels on the film only allow water molecules to pass through, while other substances are isolated. Compared to traditional filtering materials, this new type of graphene film can be reused, even if the surface is blocked by some impurities and pollutants, it can still ensure filtering performance. At present, experimenters are intensifying the testing of the practicality of the thin film. In fact, this is not the "brilliant debut" of graphene oxide thin film. Prior to this, this material has made significant progress in fields such as gas separation and ion filtration. Previously, a study by the University of Manchester showed that graphene oxide films immersed in water will undergo some deformation, making the pore size of the film larger, so smaller ions will pass through the film with the water flow, while larger ions or molecules will be blocked, which plays a role in filtering to a certain extent.
Now, the research results of the research team of the University of Manchester show that these graphene oxide films have been further optimized to avoid the pore expansion caused by water flowing through the film. Importantly, this time they were able to control the pore size of the graphene oxide film, which can effectively block unwanted ions. The water filtered by this graphene film can be consumed and is safer. Undoubtedly, this achievement has significant practical significance. On the one hand, according to the Sustainable Development Goals, by 2030, everyone in the world will have access to basic freshwater resources, but the current situation is not optimistic. On the other hand, climate change is also putting people on the brink of water security threats, with droughts, floods, and glacier melting all leading to shortages of freshwater resources. *Going forward, these factors will further affect food production, healthcare, energy, and industry. The scarcity of freshwater resources has posed an undeniable threat to humanity. It is predicted that by 2025, 14% of the world's population will face the threat of water scarcity. This technology is expected to revolutionize filtration water technology within its scope, especially for those who cannot afford to establish large-scale desalination plants. According to this research result, people can design the pore size of graphene oxide films as needed to achieve "on-demand filtration". There are abundant water resources on Earth, and the ocean is our reservoir of abundant water resources. If we can manufacture this membrane system on a large scale for seawater desalination, the freshwater crisis can be effectively solved. At present, many developed countries are increasing investment in seawater desalination technology, so this technology is also in a critical period of development. If this seawater desalination technology can be widely promoted, it can directly filter and extract water from the sea, eliminating the need to worry about freshwater scarcity.
The molecular sieve adsorber adopts a double-layer bed structure (activated alumina+molecular sieve). The bottom layer of activated alumina bed can effectively protect the molecular sieve and prolong its service life. At the same time, the use of double-layer bed also reduces the regeneration resistance and temperature of the adsorber, saving regeneration energy consumption. The switching system adopts a shock free switching valve with a speed regulator to ensure slow valve opening and uniform speed. The pressure equalizing valve adopts split range control to ensure a smooth inflation process. The sewage nitrogen vent valve adopts a pre opening method to prevent pressure build-up in the tower. The switching system adopts DCS automatic control and is equipped with automatic pressure difference judgment, combined with valve position feedback signal. It can fully ensure the reliability of the switching system. The pressure equalization adopts imported valves with similar forward and reverse flow capacity and good regulation performance to ensure the relative stability of the operating conditions during the regeneration process of the device. The steam heater for regeneration adopts a double tube plate structure steam heater, ensuring the safe operation of the molecular sieve adsorber from both structural and process aspects.
