A safe, environment-friendly and energy-saving fuel-filling device comprises a fuel-storage tank 1, a fuel dispenser, a skid body 3, a hood body 5 and a counter-impact foundation 4. The storage tank 1 is connected with the fuel dispenser via a fuel outlet piping 11. The skid body 3 is encased in the hood body 5 above it. The fuel-storage tank 1 and fuel dispenser are mounted on the skid body 3 such as to compose a mobile fuel-filling station. The skid body 3 is bolted onto the ground. The storage tank 1 is a double-walled tank. The inner cavity of the storage tank 1 and the interlayer formed between the double walls are filled with explosion-resistant separating materials. The fuel dispenser is in a split installation, and it includes a digital electronic display 21, a fuel pump case body 22 and a fuel injector 23. The digital electronic display and the fuel injector 23 are set up on the outer side of the hood body wall. The fuel pump case body 22 is set up in the space inside the hood body 5 and outside the storage tank 1, and it is fixed on the skid body 3. A bracket is provided under the digital electronic display on the outer wall of the hood body 5 to support the injector 23. An outlet fuel pipe 11 of the storage tank 1 is connected onto the fuel pump case body 22. An outlet fuel hose on the fuel pump case body 22 is connected onto the injector 23 through the wall hole of the hood body 5. A fuel gas recovery device is set up on the storage tank 1 and comprises a breather valve 62 provided on the storage tank 1, a pipeline connecting via the breather valve to the storage tank 1 and a three way valve 63 on the pipeline. At the other end of the three way valve 63 there is a fuel gas recovery hose, the nozzle of which is joined to the gas recovery hose of the tank truck while the tank truck is transferring fuel into the fuel- storage tank 1.
