Abstract
The utility model discloses an air intake mixing regulating device and a gas power generator set with the air intake mixing regulating device. The air intake mixing regulating device comprises a commingler used for mixing natural gas and air and a regulator used for regulating an air intake quantity of the mixed gas, wherein the gas outlet end of the commingler is connected with the gas inlet end of the regulator, and the gas outlet end of the regulator is connected with the intake pipelines of air cylinders. Due to the fact that the technology of shifting the commingler backward to the front of the regulator is adopted, in the intake pipelines before the mixed gas enters the air cylinders, only short sections of pipelines between the commingler and the regulator contains the mixed gas with the natural gas, the mixed gas with the natural gas is prevented from existing in an empty intercooling section, the possibility of the leakage of the natural gas is greatly reduced, and the safety performance of the gas power generator set is improved.
Description
Technical field
The utility model relates to natural gas power unit and air inlet and mixes the controlling device field, and in particular a kind of air inlet that improves natural gas power unit usage safety performance mixes controlling device.
Background technique
Nowadays; day by day in short supply along with gasoline and the diesel oil energy; and people are to the raising of environmental protection consciousness; the rock gas that price is more cheap becomes alternative gasoline and diesel oil gradually with one of clean energy resource of reducing the carbon emission amount, can greatly reduce client's cost of electricity-generating if be applied on generator set.
But the air inlet of existing natural gas engine mixes controlling device, and cold section has the mixed gas that contains rock gas in admission line absolutely empty, easily produces and leaks, and have certain potential safety hazard.
Therefore, prior art still haves much room for improvement and develops.
The model utility content

Simultaneously, the utility model also provides a kind of natural gas power unit, can improve its Safety performance.
The technical solution of the utility model is as follows: a kind of air inlet mixes controlling device, comprise: for the mixer that rock gas is mixed with air, and the regulator that is used for regulating the mixed gas air inflow, wherein, the outlet side of described mixer is connected with the inlet end of described regulator, and the outlet side of described regulator is connected with the admission line of described cylinder.
Described air inlet mixes controlling device, and wherein: the air inlet end of described mixer is connected with the output terminal of air-air intercooler.
Described air inlet mixes controlling device, and wherein: the input end of described air-air intercooler is connected with the output terminal of pressurized machine.
Described air inlet mixes controlling device, and wherein: described pressurized machine is the exhaust-driven turbosupercharger of utilizing outlet pipe to discharge.
Described air inlet mixes controlling device, and wherein: the rock gas inlet end of described mixer is connected with the output terminal of shut-off valve.
Described air inlet mixes controlling device, and wherein: the input end of described shut-off valve is connected with the output terminal of Decompression valves.
A kind of natural gas power unit comprises that air inlet mixes controlling device, and wherein: described air inlet mixes the adjusting installing and is set to the described air inlet mixing of above-mentioned middle any one controlling device.
A kind of air inlet provided by the utility model mixes controlling device and natural gas power unit thereof, regulator technological means before will be moved to owing to having adopted after mixer, in admission line before entering cylinder, only have between mixer and regulator and have the mixed gas that contains rock gas in section shorter pipeline, avoided in admission line absolutely empty cold section to have the mixed gas that contains rock gas, greatly reduce the possibility that leakage appears in rock gas, improved the Safety performance of natural gas power unit.
Description of drawings
Fig. 1 is the linkage structure schematic diagram that the utility model air inlet mixes controlling device.
Embodiment
Below with reference to accompanying drawing, embodiment of the present utility model and embodiment are described in detail, described specific embodiment only in order to explain the utility model, is not be used to limiting embodiment of the present utility model.
As shown in Figure 1, Fig. 1 is the linkage structure schematic diagram that the utility model air inlet mixes controlling device, this air inlet mixes controlling device and mainly comprises mixer 130 and regulator 140, wherein, described mixer 130 is used for rock gas is mixed with air, the air inflow that described regulator 140 is used for according to load match and regulate mixed gas.
In existing natural gas power unit, air directly enters mixer through filter, with after rock gas mixes, because of the pressure of mixed gas inadequate, density is lower, is difficult to satisfy the requirement of output power, therefore need to carry out supercharging to mixed gas by increasing device; In addition, also need the mixed gas after supercharging is carried out cooling processing, thus in admission line absolutely empty cold section certainly will have the high pressure mixed gas that contains rock gas, easily leak, have certain potential safety hazard.
And mix in controlling device in air inlet of the present utility model, the outlet side of described mixer 130 directly is connected with the inlet end of described regulator 140, concrete, the flange of described mixer 130 outlet sides and the flange of described regulator 140 inlet ends can be connected, and add a seal washer to get final product between two end face of flange; But the outlet side of described regulator 140 directly is connected with described air duct to cylinder 150 by pipeline.Can first the air after filtering through filter 160 be carried out supercharging and cooling thus, mix in described mixer 130 with rock gas more afterwards, even and then in admission line absolutely empty cold section leak, can not produce danger yet because leak only have air but not contain the mixed gas of rock gas.
Mix in the preferred implementation of controlling device in the utility model air inlet, the air inlet end of described mixer 130 can directly be connected by the output terminal of pipeline with air-air intercooler 120, and filtration, supercharging, cooled air enter described mixer 130 to be mixed with natural gas phase.
Concrete, the input end of described air-air intercooler 120 can directly be connected by the output terminal of pipeline with pressurized machine 110, and the air after filtration, supercharging enters described air-air intercooler 120 and carries out cooling.
Be preferably, described pressurized machine 110 can be selected turbosupercharger, and utilizes the waste gas of natural gas engine self outlet pipe discharge to drive, to take full advantage of the energy of waste gas.
Concrete, the rock gas inlet end of described mixer is connected with the output terminal of shut-off valve 170, and the input end of described shut-off valve 170 is connected with the output terminal of Decompression valves 180, and the input end of described Decompression valves 180 directly accesses rock gas.
Mix controlling device based on above-mentioned air inlet, the utility model has also proposed a kind of natural gas power unit, comprise that air inlet mixes controlling device, wherein: described air inlet mixes the adjusting dress can be set to the described air inlet mixing of above-mentioned middle any one controlling device, thus, leaking appears in the mixed gas of having avoided containing rock gas, has improved the Safety performance of complete machine.
