The invention discloses a commingler of a natural gas engine capable of improving the vacuum degree of an air suction port and mixing the sucked air and natural gas rapidly and uniformly. The commingler comprises a pipe body and a flow guide fan arranged at the port of an air intake end of the pipe body, wherein the air intake end of the pipe body is symmetrically provided with an air intake pipe and a natural gas intake pipe which are communicated with the pipe body; the included angles between the air intake pipe and the pipe body and between the natural gas intake pipe and the pipe body are both greater than 90 degrees; the air intake ends of the air intake pipe and the natural gas intake pipe are respectively provided with an end cover; the end covers are provided with air intake holes; and the air intake holes are internally provided with filtration media. By adopting the commingler provided by the invention, air and natural gas can be mixed fully and uniformly, thus the mixed gas is combusted more fully in the engine, and under the condition of the same output power, the consumption of natural gas is lowered.
Description
Technical field
The present invention relates to a kind of mixer for natural gas in use, refer more particularly to a kind of mixer for natural gas in use for natural gas engine.
Background technique
Along with the consumption of global energy, price of oil going up sky-high novel industry occurred in automobile industry, and namely to the existing traffic tool, wish realizes the purpose of " oil changes gas " by the gas burning system of street rod, thereby reaches the purpose of saving cost.As everyone knows, motor is the heart of automobile, has undoubtedly become the key object of " oil changes gas ".Natural gas engine when operation, after air filters through air filter, after mixing in mixer with rock gas, enter the closure of motor.
The applying date is: August 27, denomination of invention were in 2007: used for diesel engine diesel gas double fuel air mixer, the patent No. are: 200720091634.8 Chinese invention patent discloses a kind of used for diesel engine diesel gas double fuel air mixer, but the rock gas that this mixer inspiration is enough, improve the degree of vacuum of mixer intakeport, but record is not carried out mixed uniformly structure with air and rock gas fast; And, need to dispose special L-type rock gas suction tude at air mixer, L-type rock gas suction tude is stretched in the main body of mixer, rock gas could be mixed with air in flowing into the mixer main body.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of and can improve the degree of vacuum of intakeport and the Commingler for natural gas engine that air and the rock gas Quick uniform of inspiration can be mixed.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Commingler for natural gas engine, comprise: body and the flow-guide fan that is arranged on body inlet end port, the inlet end of described body is symmetrically arranged with air intake duct and the rock gas suction tude that communicates with body, the angle of air intake duct and rock gas suction tude and body is all greater than 90 degree, the inlet end of air intake duct and rock gas suction tude is respectively arranged with end cap, offer inlet hole on the end cap, be provided with filter medium in the inlet hole.
Respective side in air intake duct and rock gas suction tude on the inwall of described body is respectively arranged with at least one convex ridge, and the convex ridge of these inboard wall of tube body both sides staggers mutually.
Described body length is L, and the width of convex ridge is W, then the number N=(L-3 of convex ridge)/2W.
The height and the width of described convex ridge equate, all are not more than half of internal diameter of tube body.
Described filter medium is stainless (steel) wire.
The concrete structure of described flow-guide fan comprises: rotating shaft and several circumferentially evenly are arranged on the helical guide vane in the rotating shaft.
Described air intake duct links to each other by arc pipe with the connecting end of rock gas suction tude.
Described flow-guide fan is arranged on the inlet end port of body by the disc type bearing, has been evenly arranged several vent holes on the disc type bearing.
Described flow-guide fan is arranged on the inlet end port of body by the frame type bearing that is made of inside and outside inner frame and the spoke that is connected inside and outside skeleton.
Beneficial effect of the present invention is as follows:
1, because air intake duct, rock gas suction tude and body are cylindrical body, need not to use again such as the L-type natural gas tube and stretch in the mixer, simple in structure linking up; Air intake duct and rock gas suction port are symmetrically distributed in the both sides of body, and all spend greater than 90 with the angle of body, so that air-flow is more smooth and easy, are convenient to air and rock gas rapid mixing; Be positioned at the flow-guide fan of body inlet end port, when mixed gas is flowed through this guide vane, drive the guide vane rotation, mixed gas is stirred, be mixed to get more even; Be provided with by the end cap that offers a plurality of inlet holes and be arranged on the filtrating equipment that the filter medium in the inlet hole consists of at the inlet end of air intake duct and rock gas suction tude, prevented that effectively outside foreign material from entering mixer;
2, be provided with a plurality of convex ridges owing on the inwall of body, stagger along the center line of air intake duct and rock gas suction tude respectively, speed increases when mixed gas is flowed through convex ridge, produce easily whirlpool, increased the area of contact of two-phase gas, mixed gas is subject to the extruding of convex ridge, shorten the distance between the two-phase, further promoted the mixing of gas;
3, come the reasonable Arrangement convex ridge according to the width of convex ridge self and length, the internal diameter of body, when promoting that gas mixes, guaranteed the unimpeded of air-flow;
4, air intake duct links to each other by arc pipe with the rock gas suction tude, so that mixed gas can flow in the body fully glibly, further facilitates air and rock gas rapid mixing.
Adopt mixer of the present invention, can be with air and the full and uniform mixing of rock gas, so that mixed gas burns is more abundant, in the situation of same output power, reduced the consumption of rock gas in motor.
