Problems solved by technology

[0006] However, the mixers of existing natural gas engines at home and abroad are generally designed for high-concentration natural gas, and the methane concentration in coalbed methane will not only change with the place of production, season and time, but also change with the thickness of the coal seam. Variations may be between 30%-90%
Such drastic changes in methane concentration will not only cause changes in the output power of natural gas engines, but also cause severe overheating of the engines
At the same time, large-scale changes in methane concentration will also affect the operating stability of the engine, greatly reducing the efficiency of the natural gas engine, and even making the engine unable to operate normally and safely

Embodiment

[0024] Electronically controlled double-valve gas fuel mixer, the mixing chamber casing 2 is a three-way tubular shape, and the nozzles on both sides are respectively connected to the gas valves. The gas valve on one side is the air valve 1 and the gas valve on the other side is the gas valve 3. The other side pipe of chamber housing 2 is a Venturi throat type, and the lower part of the Venturi throat is a throttle valve 9, see figure 1 with figure 2 .

[0025] The air valve includes an outer sleeve 12. One side of the outer sleeve 12 is an outlet 13, and the other side is an inlet 14. The inlet 14 is connected to a trachea 15, and the trachea 15 extends into the outer sleeve. An air port 16 is provided, and an inner sleeve 17 is set on the air pipe 15. The inner sleeve 17 is axially connected with a stepping motor through a shaft extending to the outside of the outer sleeve 12. The stepping motor is located outside the outer sleeve 12, and the inner sleeve 17 On the 17, an...

Abstract

The present invention relates to an electrically-controlled double-valve type gas fuel mixer. It is characterized by that the mixing chamber shell body of said mixer is made into the form of three-way pipe, two side pipe orifices are respectively communicated with gas valves, another side pipe orifice is a venture throat type, the lower portion of the Venturi throat is equipped with a throttling valve. Said invention also provides the working principle of said gas fuel mixer and its concrete operation method.

Description

technical field [0001] This invention relates to gaseous fuel mixers. Background technique [0002] With the gradual depletion of the world's energy and the increasingly serious air pollution, the development of new low-pollution energy has become a new issue faced by countries all over the world. Among them, coal-bed methane, as the associated gas of coal mines, is being highly regarded by the governments of various countries because of its abundant reserves. Pay attention to. As a large coal mine producing country, our country is rich in coal resources, and the reserves of coalbed methane are extremely considerable. [0003] Because coalbed methane contains methane, it is flammable and harmful to the safe production of coal mines. Therefore, at present, most coal mines in my country directly pump out coalbed methane and discharge it into the atmosphere as waste gas. This will not only cause air pollution, but also a great waste of resources. Therefore, rational use of ...
