Environment-friendly energy-saving device for extracting compressed natural gas

Abstract

The invention discloses environment-friendly energy-saving device for extracting compressed natural gas and belongs to natural gas extraction techniques. An electromagnetic coil of the environment-friendly energy-saving device is arranged outside a gas pump shell. A protective shell is fixed to the gas pump shell. A gas inlet pipe is fixed to the lower end of the gas pump shell. A gas outlet valve is fixed in a center hole of the gas pump shell. An iron core spring and a magnetism-induced piston are arranged in the gas pump shell. The iron core spring is pressed on the magnetism-induced piston. A natural gas inlet channel of a gas inlet cavity is sealed through a gas passing sealing plate. A natural gas inlet channel of a squeezing cavity is sealed through a sealing ball or a sealing cone. A fixed plug is fixed in a plug hole in the magnetism-induced piston. The sealing ball or the sealing cone is installed in an internal conical hole of the magnetism-induced piston. The environment-friendly energy-saving device for extracting the compressed natural gas is compact in structure, small in vibration, high in electric energy utilization rate, strong in power and suitable for extracting the natural gas from a natural gas well; the industrial market prospects are good, the commercial value is high, and both manufacturing and using are quite convenient.

Description

technical field [0001] The invention relates to the technical field of natural gas exploitation, in particular to an environment-friendly, energy-saving pressure-feeding natural gas extraction device for pumping natural gas in a natural gas well. Background technique [0002] Traditional natural gas is extracted by compressing the natural gas with an air pump of a crank linkage mechanism, which has a large volume and low working efficiency. For this reason, we have designed natural gas extraction equipment with small volume and high extraction efficiency. Contents of the invention [0003] The purpose of the present invention is to provide an environment-friendly and energy-saving pressure-feeding natural gas extraction equipment with high utilization rate of electric energy and high-efficiency pumping of natural gas and its method. [0004] In order to achieve the above purpose, the environmental protection and energy-saving pressure-feeding natural gas extraction equipm...
