Embodiment
With reference to specific attached drawing, the utility model is described in further detail.
As shown in Figure 1, anti-explosion diesel engine for mine described in the utility model transfinites, gas shield device includes host 11, main
Machine 11 includes flame proof cavity 13, and microprocessor 14, intake valve 15 and explosion-proof wiring terminal 16, microprocessor are equipped with flame proof cavity 13
Device 14 connects power supply, shutdown solenoid valve 3 and the sensor for gathering engine indices, sensor respectively includes explosion-proof oil
Door sensor 4, explosion-proof cooling-water temperature sensor 5, the explosion-proof gas sensor 6 that transfinites, explosion-proof speed probe 7, explosion-proof pressure sensor
8；The effect for shutting down solenoid valve 3 is that the autostop of engine is realized when index exceeding standard；The intake valve 15 row of connection respectively
Qi leel pipe 2 and inlet manifold 1, exhaust charge 2 divide gas port to connect with exhaust main；Exhaust charge 2 is equipped with cooler 9
With spark arrester 10, the effect of cooler 9 is to reduce the temperature for the tail gas being diverted, and it is no more than 120 DEG C；Spark arrester 10
Effect be go out cigarette remove tail gas in spark, or prevent because engine flashback produce spark；The intake valve 15 uses snail
The single-direction transmission mode of worm and gear, can prevent the maloperation produced by engine suction negative pressure while fine motion is realized；It is anti-
The effect of quick-fried wire connection terminal 16 is to separate Wiring port and flame proof port, is a kind of Security Techniques；The flame proof cavity
13 are equipped with anti-riot respirator 17, and the effect of explosion-proof breather device 17 is when host 11 during extraneous progress gas exchanges with carrying out the flame that goes out
Effect, prevents the spark that host 11 produces in extreme circumstances to be delivered in outer air.
The operation principle and the course of work of the utility model：As shown in Figure 1, increased on the quick-fried diesel exhaust gas manifold in place where troops were originally stationed
One point of gas port, distributes a part of tail gas, this partial tail gas is cooled the laggard excess of imports by exhaust charge 2 through cooler 9
Limit gas shield device host 11, the microprocessor 14 in host 11 reads the engine emission parameter for analyzing each sensor collection
Afterwards, the openings of sizes of intake valve 15, tail in being controlled accordingly into inlet manifold 1 according to the actual emission for the gas that transfinites are controlled
The size of tolerance, the tail gas of shunting participate in burning again, reduce the concentration and temperature of burning indoor oxygen in combustion,
The discharge capacity of more than 50% NOx can be at most reduced by actual measurement.
As shown in table 1, after testing, under comprehensive operating mode, NOxDischarge capacity reduces by 31.5%, and highest optimization rate is 52.2%.
