Abstract
The utility model provides a safety device capable of avoiding detonation of an engine exhaust pipe. A cylinder which is connected with a crank case of the engine is connected with a silencer through the exhaust pipe; the exhaust pipe is connected with a scavenging air tube; the scavenging air tube is communicated with an air compression and delivery device through an air control valve; and the air compression and delivery device is an air compressor or an air compression pump. The safety device is used for avoiding detonation of the engine exhaust pipe, and guarantees safety of operators and surrounding people and normal production.
Description
Technical field
The utility model relates to a kind of safety installations of avoiding the engine exhaust pipe detonation.
Background technique
At present; The gas compressor that in oil gas field, is used for compressed natural gas; Particularly two stroke IC engine the exhaust explosion phenomenon often occurs, if the engine power minor danger is not very big in work in service or start-up course; But heavy duty is if exhaust explosion, and consequence is very serious.Like the DPC-2804 compressor bank of Shengli Oil Field Dongying compressor station by the manufacturing of U.S. storehouse C Compaq; The power that is equipped with is 600KW combustion gas two stroke IC engine; When exhaust explosion appears in this unit; Strong wallop is raised the All-weather shed roof of scene up to 15 meters, tear through regular meeting, even the umbrella crown of the 20kg that will weigh is got 60 meters far away.Operator and personnel's personal safety are on every side caused very big threat.
The reason that causes the internal-combustion engine vent-pipe detonation is because the cylinder that the inflammable gas in the cylinder of internal combustion engine does not have to have in perfect combustion or the multi-cylinder engine does not have igniting to cause inflammable gas and Air mixing gas to get into outlet pipe; When mixed gas runs into Mars or other cylinders very during the smoke evacuation of high-temperature; Reach burning-point and just produced blast; Thereby the generation exhaust explosion is commonly called as motor and " blows out "." blowing out " phenomenon of motor appears in the engine starting process the most easily; Because the impossible ignition operation simultaneously of cylinder at the moment of startup motor; And each cylinder also can not all be all igniting smoothly after first time suction stroke, so engine starting process is the hour of danger that " blowing out " phenomenon takes place.
Summary of the invention
The purpose of the utility model is intended to overcome the deficiency of existing technology, and a kind of safety installations that can avoid the engine exhaust pipe detonation is provided.
The purpose of the utility model can realize through following technical measures:
The cylinder that connects engine crankcase connects baffler through outlet pipe, and outlet pipe is connected with scavenging air pipe, and scavenging air pipe is communicated with the air compression feedway through air shut-off valve.
The purpose of the utility model also can realize through following technical measures:
Described pressurized air compression conveyor is air compressor or air pressure pump.
When motor is large-scale or medium duty engine and not having under the situation of other source of compressed air, need configuration one mini air compressor, when motor when being small-sized or miniature, a configurable small air compressor pump.
The utility model is made up of a mini air compressor or air pressure pump and air shut-off valve etc.; Connect a scavenging air pipe from the gas holder of air compressor or the air pump that contracts to the cylinder outlet of motor; With valve control,, open air shut-off valve and in outlet pipe, be blown into air when before the engine start or last time started successfully need not start once more the time; Burning mixture in the outlet pipe is purged clean; Carry out startup next time again, so just avoided the possibility of engine exhaust pipe generation detonation, guaranteed operator and personnel's the personal safety on every side and the safe operation of production.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
The crankcase 8 that motor is connected with axle 11 connects the piston 9 that is positioned at cylinder 5 through piston rod 10; The cylinder 5 that connects gas inlet pipe 6 connects baffler 1 through outlet pipe 3; Outlet pipe 3 is connected with scavenging air pipe 4, and scavenging air pipe 4 is communicated with air compressor or air pressure pump 2 through air shut-off valve 7.
Claims (2)
