Oil tank truck tank Working principle of the body:
: Stretch the vortex hot film heat exchanger into the bottom of the oil tank along the radial direction of the storage tank. The heat medium (steam) flows through the tube side, and the oil flows between the inner tubes on the shell side. The body suction port is directly connected to the medium in the tank.
: Set a temperature control valve at the steam inlet of the heat exchanger, and control the steam inlet of the heat exchanger by detecting the temperature of the oil outlet with a temperature sensor probe to ensure a constant oil temperature.
: The heat exchanger uses high-efficiency heat exchange elements vortex hot film tubes to maintain a reasonable flow of oil between the tubes. The thermal efficiency is twice that of ordinary heat exchangers. Its enhanced heat transfer mechanism is: the oil fluid flows on the inner and outer surfaces. It is designed to have turbulent flow, which produces strong oscillation and scouring effects. The direction of the flow is constantly changing. The high-temperature oil fluid close to the surface of the pipe wall is constantly replaced. The insulation layer becomes thinner and even destroyed. The heat transfer on the metal surface accelerates, and the fluid The microscopic vortex is strengthened, which strengthens the thermal diffusion inside the oil fluid. The fluid close to the pipe wall surface will not be overheated at local high temperatures, so the oil can be properly and fully heated without the possibility of coking and decomposition. It transfers heat well without causing great resistance.
: Heating features:
: , fast heating speed, high heat transfer efficiency, and not easy to scale.
: It can quantitatively heat oil products, heating as much as needed.
: The oil will not suffer from local high temperature or carbonization, ensuring the quality of the oil and the heat transfer efficiency of the heater.
: The oil outlet temperature in the oil tank is the highest, ensuring the fluidity of the poured oil.
: It avoids repeated heating of the oil in the tank, ensures the color of the oil, and reduces the cost of oil treatment.
: , long service life, corrosion resistance, high temperature resistance, high pressure resistance, and anti-fouling functions, which greatly improves the overall performance of the heat exchanger.
: The advanced process structure design ensures the smooth outflow of oil products and better pumping effect at the bottom of the tank.
: , can realize automatic control, and can control the steam feed amount according to the inlet and outlet temperature of the oil and the oil pouring flow rate.
: Compact structure, easy installation and maintenance, and the installation of the heater will not affect the safety of the tank. Compared with the profiled tube heat exchanger, under the same heat exchange area: the external dimensions of the vortex hot film heat exchanger are only about half of the external dimensions of the profiled tube heat exchanger.
: Compared with the electric heating method, it is safer, the heating is gentler, and it has less impact on the quality of the oil.
: Comparison between new heating technology and traditional tube-type oil tank heating:
: Heating method, heat medium oil output, heating temperature, heating time, condensate water temperature, steam consumption

: Safety precautions editor () to prevent personal electrification. During loading and unloading operations, the human body must come into contact with the work object (gas truck) and work objects to generate friction, which will easily generate static electricity and may form electrostatic discharge. If flammable and explosive oil vapor happens to be encountered at this time, An explosion will occur. Operators must wear anti-static overalls and anti-static shoes during operation, the purpose of which is to ground the human body. In addition, the shoes worn should be thin nylon socks or other conductive socks. It is strictly forbidden to paste insulating film on the anti-static soles and should be inspected regularly.
: () Static grounding cannot be ignored. From the perspective of a fuel truck, the main areas where static electricity is generated are pumps, filters and pipelines. The amount of static electricity generated by the tanker filling system is much higher than that of above-ground pipes. For static electricity hazards, the following measures must be taken:
: Connect the ground wire before filling the oil, and frequently check its integrity and whether the ground resistance meets anti-static standards.
: When filling oil, the crane tube must be extended to the bottom of the oil tank. The distance between the tube mouth and the bottom of the tank should be kept at left and right, and the initial filling speed should be strictly controlled within the range. The flow rate should be gradually increased until the oil outlet is submerged. However, The maximum flow rate shall not exceed . to prevent electrostatic accidents caused by splashing
: After filling the oil, the grounding must be disconnected after the oil has stabilized. Because after the oil is installed, the oil level potential will be maintained for several minutes due to the flow of oil in the tank.
: Don’t let your guard down just because you have a good grounding. Static electricity grounding can only dissipate static electricity on conductors (metals, human bodies, conductive liquids, etc.) that are closely connected to it, but it cannot conduct static electricity on isolated conductors and non-conductors (oil, rubber, resin, glass, etc.) that are not connected to it. However, it is powerless or difficult to eliminate in a short period of time. Therefore, while grounding static electricity, operators should also strictly follow operating procedures and pay attention to hidden dangers that may arise at any time. At the same time, they must master the emergency methods and rescue measures to correctly handle various emergencies. Measures
:) Attention should also be paid to accidents caused by oil conversion. This kind of accident mainly occurs when a tank filled with gasoline is used to hold diesel. The flash point of gasoline is lower than that of diesel. If diesel is injected into a tank containing gasoline vapor, the gasoline vapor will be reduced due to absorption by the poured diesel. Small pressure, then air is sucked into the tank, and a flammable mixture is formed somewhere between the liquid surface and the air suction point. An explosion may occur when static electricity accumulates and discharges. Therefore, when it is necessary to change the oil filling, the gasoline in the tank must be cleared first, and the operation must be carried out in strict accordance with the operating procedures.
: () Use equipment that meets technical specifications and safety requirements. The automatic control, remote control, measuring instruments, valves and other equipment of the oiling station must be regularly inspected and calibrated, and relevant management systems must be formulated. In particular, the material of the oiling equipment cannot be underestimated. At the same time, you cannot make do with static grounding devices. You must strictly follow the specifications, install them carefully, and inspect them regularly. For those that commonly use clamps and magnetic connectors for grounding, they should not be clamped or adsorbed on random parts of the tanker truck, even on the painted surface. This is extremely detrimental to anti-static and is a major hidden danger. Many users are looking for temporary benefits when buying cars, but they don't know that you get what you pay for. Inferior equipment can easily cause accidents. You should pay more attention to dangerous goods vehicles such as oil tank trucks.
