Embodiment Construction

[0012] According to the picture:

[0013] The natural gas source is transported from the external network through the delivery pipe to the dehydration tank 1 of the natural gas mother station, and the dehydration tank of the natural gas mother station is connected to the charging machine 2 through a pipeline.

[0014] 1. The first level of filling: the skid car 3 is filled under the condition of the external network pressure of 6PM in the dehydration tank of the natural gas mother station;

[0015] 2. The second stage filling: start the first stage charging machine 2.1, and fill the skid car 3 with a pressure of 16MP;

[0016] 3. The third stage filling: Start the second stage charging machine 2.2 to fill the skid car 3 with natural gas at a pressure of 25MP until the allowable pressure requirement of the skid car is reached.

[0017] Features:

[0018] The use of three-stage pressure for natural gas filling of the skid car, and equal pressure filling can save energy, reduce...

Abstract

The invention provides a method for filling prying vehicles by three-level pressure of a natural gas primary station. A natural gas source is conveyed into a dehydration tank of the natural gas primary station by a conveyor pipe by virtue of an external network and the dehydration tank of the natural gas primary station is communicated with a pressurizing machine by a pipeline. The first level of filling, the second level of filling and the third level of filling are performed. By filling natural gas by three-level pressure, the method achieves the technical purpose of energy-efficient filling of the natural gas. The method has the characteristics of energy conservation and safety.

Description

technical field [0001] The invention proposes a method for three-stage pressure filling of a skid car at a vehicle natural gas mother station in the energy field. Background technique [0002] The existing natural gas mother station usually uses a single-stage high-pressure system to fill the pry truck, and the filling is about 25PM. The disadvantage is that when the high pressure directly fills the low-pressure storage tank with natural gas, it is easy to Wind noise is generated, and the impact force on the tank body is also relatively large, and more importantly, the energy consumption is large, thus causing a waste of energy. Contents of the invention [0003] In order to overcome the existing shortcomings of natural gas skid car filling, the invention proposes a three-stage pressure filling method for natural gas. This method is filled with natural gas stages. Solve the technical problems of natural gas energy-saving filling. [0004] The scheme that the present inv...
