The core technology of skid-mounted gas station: double-barrier explosion-proof technology
At present, there are two main explosion-proof technologies for inflammable and explosive dangerous chemicals. One is to install an explosion-proof device inside the tank to inhibit the burning of emotional gas, which is the mainstream explosion-proof technology adopted by developed countries in Europe and America. It has the advantages of obvious explosion-proof effect, no influence on the normal use function of the oil tank, no pollution to oil products, simple installation and maintenance, and low cost. However, there is a single explosion-proof method. For example, in the extreme case of shooting the oil tank, the explosion-proof function fails; The other is to fill the tank with magnesium (aluminum) alloy barrier explosion-proof material, which has been widely used in China. However, the practical application results show that although it has a good explosion suppression effect, there are many problems after filling the inner tank with barrier explosion-proof materials, such as easy material breakage, blocking the oil pipeline, difficult cleaning in the tank, oil pollution, short service time and high cost.
At present, only Zhongzhou Energy Technology (Shenzhen) Co., Ltd. has developed dual explosion-proof technologies of inert gas suppression and magnesium (aluminum) alloy barrier explosion-proof, and at the same time produced skid-mounted refueling devices with dual explosion-proof technologies. The technology is advanced, which completely overcomes the technical difficulties caused by simply filling the barrier explosion-proof materials, and also avoids the problem of single explosion-proof mode caused by simply using the explosion-proof technology of erotic gas combustion suppression. The product quality has reached the world-class level.
The explosion-proof skid-mounted refueling device developed and produced by Zhongzhou Energy Technology (Shenzhen) Co., Ltd. combines explosion-proof device technology with barrier explosion-proof technology. National utility model patents have been obtained (patent number: double explosion-proof skid-mounted refueling device ZL201320 38510.5 and skid-mounted gas suppression explosion-proof device ZL20 1320384494.9). At the same time, two other invention patents applied by our company (application number: double explosion-proof skid-mounted refueling device 20 13 1027084.3 and skid-mounted explosion-proof device 20131kloc-0/39.3) have passed the preliminary examination. The fire-proof and explosion-proof function of the whole machine has passed the testing and certification of China Special Equipment Testing Institute (reportNo.: 14IF025-IQ0 1), and a high-level oil unloading and spill-proof device has been set up. Safety accessories, such as high-low liquid level alarm system, high-temperature automatic oil cut-off protection valve for tanker pipeline, emergency pressure relief device for storage tank, interlayer leakage monitor, hanging automatic dry powder fire extinguisher, etc., are extremely safe oil storage and transportation devices, which fully meet the requirements of relevant national specifications, and their safety performance is higher than that of conventional gas stations, reaching the world-class level, with broad application prospects.
Inert gas explosion suppression technology
Because the outside of the tank is heated by fire, general inert gases such as nitrogen and carbon dioxide are directly charged into the explosion suppression device. With the increase of temperature, when the inert gas reaching 230℃ starts to erupt, it has exceeded the critical temperature of nitrogen 144℃, the steam pressure has reached about 70MPa, the critical temperature of carbon dioxide has exceeded 30℃, and the steam pressure has reached about 30MPa. Ordinary explosion suppression devices, especially temperature-controlled starting devices, can't bear such high pressure when the pressure range is less than 4MPa, so it is not feasible to directly charge ordinary inert gases such as nitrogen and carbon dioxide into the explosion suppression devices.
In order to solve the above problems, after years of efforts and experiments, our company has developed an explosion suppressant which is composed of a variety of alcohols and ammonium compounds. The explosion suppressant has both fire extinguishing performance and explosion suppression performance. At the start-up eruption temperature of 230℃, the internal pressure of the explosion suppressant does not exceed 65438±0 MPa, which meets the pressure range of the temperature-controlled start-up device. Explosion suppressants need to undergo more complicated chemical reactions in the preparation process. It is necessary to accurately control the proportion of each component and adjust it to a suitable PH value. The purity of various additives is high, and the performance of the explosion inhibitor generated after meeting the above conditions is relatively stable, and the service time can reach 10 year.
The explosion suppression mechanism and production technology of this explosion suppressant belong to the core technology of our company, and other domestic peers can't copy the production at all. The explosion suppression effect and various performance indexes have surpassed those of European and American companies, and it belongs to the most advanced explosion suppression agent in the world.
At the same time, as the initial eruption temperature of 230℃ is required, the temperature application range of common temperature control materials such as tin alloy is not more than 100℃, so it is difficult to find temperature control materials suitable for such high temperature in China. Therefore, our company cooperated with a German research company to specially develop a temperature control device suitable for our company, which has high temperature resistance, accurate control accuracy and explosion-proof function. The technical scheme and processing scheme of the device are put forward by our company, and the raw materials are provided by German scientific research companies, and the two sides cooperate in research and development. The device adopts the world's most advanced temperature control materials to meet the requirements of extreme conditions, and its technical level has already surpassed that of ordinary domestic counterparts and reached the world-class level.
Equipment advantages:
1, oil is safer.
Explosion-proof technology has won many national patents, and it will not explode in case of fire, shooting, magnetic collision and lightning strike. The national authoritative testing organization has tested and certified the explosion-proof function of the double explosion-proof skid-mounted refueling device. The device was tested and verified by the highest authoritative testing organization in China (China Special Equipment Testing and Research Institute) with the cooperation of the armed police and fire officers and soldiers.
After the test of time, over the years, nearly 500 explosion-proof skid-mounted refueling devices in use in Zhongzhou have never experienced spontaneous combustion or explosion accidents, and their safety configuration is higher. Zhongzhou double explosion-proof refueling device is also equipped with high unloading and overflow prevention device and high and low liquid level alarm system. Tank car pipeline high-temperature automatic oil cut-off protection valve, storage tank emergency pressure relief device, interlayer leakage monitor, suspended automatic dry powder fire extinguisher, etc. , with advanced configuration superior to traditional gas stations, is an extremely safe oil storage and refueling device.
2. It is more convenient to use oil
Refueling is more time-saving, and can be completed in enterprises, stations and parks without leaving home, which greatly saves the air consumption and queuing time on the way to social gas stations. The procedure is simpler. Zhongzhou explosion-proof skid-mounted refueling device belongs to the whole equipment, and it is not necessary to apply for planning permission and add buildings and structures. The device is for internal use of the enterprise, and the well is not under the jurisdiction of the Industry and Commerce, Taxation and Economic and Information Committee. Therefore, the well can be put into use without going through the relevant procedures, and it only needs to obtain the permission documents from the fire department or the safety supervision department, and the approval period is short, generally within two months, which is greatly simplified compared with the procedures of social gas stations.
3. Oil is more legal.
Zhongzhou explosion-proof skid-mounted refueling device has all the conditions for obtaining administrative approval documents for legal storage and use of refined oil. People's Republic of China (PRC) GB50 156-20 14 * * and Article 3.0.3 of the national standard (Code for Design and Construction of Automobile Filling Stations) stipulate that the skid-mounted refueling device can be used by enterprises for their own use, but it must be approved by the fire safety supervision administration. Its design and installation shall conform to the current industry standard "Technical Specification for Gas Stations with Skid-mounted Refueling Devices" SH/T3 134. Our products fully meet the technical requirements of this standard and all the conditions for handling such administrative licenses. The practical application case has been recognized by the local government departments such as fire control and safety supervision.
4. It is more economical to use oil
De-intermediation can directly wholesale the refined oil to qualified oil suppliers, and store it through Zhongzhou skid-mounted refueling device, saving the price difference between wholesale and retail and bringing huge economic benefits to enterprises. The investment is small, and the construction cost of building a conventional underground storage tank gas station is generally 5- 10 times that of setting up an explosion-proof skid-mounted refueling device in Zhongzhou.
5. It is smarter to use oil.
The device is equipped with a series of intelligent facilities such as IC card refueling management system, which can realize the functions of network management, self-service refueling, automatic unloading control, oil leakage online monitoring, acousto-optic automatic alarm, remote monitoring and unattended operation. Intelligent networking self-service explosion-proof skid-mounted gas station fills the domestic technical gap and has a high level of informationization and intelligence.
