Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] like figure 1As shown, according to the first embodiment of the present invention, the natural gas pipeline dosing device includes an energy conversion unit, an electronic control unit and a first filling unit. The energy conversion unit converts the pressure energy of the natural gas in the natural gas pipeline into hydraulic energy and electric energy. The first filling part communicates with the energy conversion part, and is driven by the energy conversion part to fill the first filling agent into the natural gas pipeline. The electric control unit is electrically connected with the energy conversion part, and obtains electric energy from the energy conversion part. The electric control...

Abstract

The invention provides a chemical dosing device for a natural gas pipeline. The chemical dosing device for the natural gas pipeline comprises an energy conversion portion, a first filling portion and an electronic control unit. The energy conversion portion is used for converting pressure of natural gas in the natural gas pipeline into hydraulic energy and electric energy. The first filling portion is communicated with the energy conversion portion and is driven by the energy conversion portion to fill first filling agents into the natural gas pipeline. The electronic control unit is electrically connected with the energy conversion portion and the first filling portion and is used for controlling the filling amount of the first filling portion. By means of the chemical dosing device for the natural gas pipeline, chemical dosing can be carried out under the condition that no extra power source is added, and the chemical dosing amount can be accurately controlled.

Description

technical field [0001] The invention relates to auxiliary equipment for natural gas exploitation and transportation, in particular to a natural gas pipeline dosing device. Background technique [0002] During the production process of natural gas, some unfavorable environmental and geological conditions will affect the normal production of natural gas. For example, when the ambient temperature is low, ice blockages are likely to occur in the gas pipeline, resulting in poor gas transmission; when the underground water output is too large, the natural gas is suppressed by the water pressure, resulting in a decrease in gas production. In order to overcome these unfavorable environmental factors and ensure the normal production of natural gas, it is necessary to inject methanol into the natural gas pipeline or inject foaming agent into the well. [0003] The existing schemes for adding methanol or foaming agent are as follows. The self-operated high-pressure alcohol injection p...
