Description

Technical Field

[0001] The utility model relates to the technical field of pump skids, in particular to an integrated pump skid with an integrated horizontal storage tank. Background Art

[0002] A gas filling station is a place that provides fuel to natural gas vehicles (NGV) and CNG\LNG trailers in the form of compressed natural gas (CNG) or liquefied natural gas (LNG). LNG is transported to the gas filling station by cryogenic tank trucks. After the pressure is increased by the unloading booster in the gas filling station, the LNG is transported to cryogenic storage tanks for storage using the pressure difference.

[0003] At present, the gas station equipment consists of a storage tank part, a pump skid part, and a liquid filling machine part; generally, a box-type integrated skid is equipped with a storage tank, a pump skid, and a closed box body, as shown in the attached manual. Figure 1 As shown in the figure, the tank and pump skid foundations are made separately and installed on independent foundations. The civil construction is more complicated and costly. The pipeline from the tank to the pump skid is installed on site, which takes a long construction period. The height difference between the tank and the pump skid causes many elbows in the pipeline, and the liquid outflow from the tank to the pump skid is not smooth. The general box-type integrated skid is completely closed, with its own cofferdam and outer box body, and the civil construction cost is low, but the cost of the whole skid is high, and the safety factor is not high enough due to the overall closure. To this end, we provide an integrated pump skid with an integrated horizontal tank to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 2-4 As shown, the utility model provides a technical solution: an integrated pump skid with an integrated horizontal storage tank, comprising a frame body, a storage tank structure and a pump skid structure.

[0025] The frame body includes an integrated bottom frame 1, a mounting groove 5 is provided on the bottom surface of the integrated bottom frame 1, a supercharger carburetor 6 is installed in the mounting groove 5, and the bottom surface of the integrated bottom frame 1 is a horizontal plate structure. After the supercharger carburetor 6 is installed in the mounting groove 5, a distance is left between it and the ground.

[0026] The storage tank structure includes a storage tank 3, which is designed to lie flat. A storage tank support 2 is fixedly connected to the storage tank 3, and the bottom end of the storage tank support 2 can be detachably installed on the integrated bottom frame 1. The storage tank 3 is supported by the storage tank support 2, and the storage tank support 2 and the integrated bottom frame 1 can be assembled on site by welding. An EAG vaporizer 7 is installed on the storage tank 3, and a vent pipe 8 is fixedly connected to the EAG vaporizer 7. The bottom end of the vent pipe 8 is fixedly connected to a support frame, and the bottom end of the support frame is fixedly connected to the integrated bottom frame 1. The bottom surface of the storage tank 3 is fixedly connected to a cylinder liquid outlet pipe 9, and the end of the cylinder liquid outlet pipe 9 away from the storage tank 3 is fixedly connected to a liquid outlet pipe 10, the cylinder liquid outlet pipe 9 is L-shaped, and the liquid outlet pipe 10 is straight.

[0027] The cylinder liquid outlet pipe 9 is located at the bottom of one end of the storage tank 3 and can transport the liquefied natural gas in the storage tank 3 to the inside of the liquid outlet pipe 10 .
