Description
Technical field
The utility model relates to a kind of diesel engine flameproof apparatus, especially a kind of four cylinder diesel engine flameproof apparatuss.
Background technique
In China, the coal underground mining is very high to the Safety performance requirement of transportation locomotive, and used transportation locomotive mostly is electric locomotive and battery car at present.But still there are many potential safety hazards in electric locomotive, and the power of battery car and cost are too high again.If the employing diesel locomotive, the necessary explosion-proof problem that solves diesel locomotive, domestic existing diesel engine does not have flameproof apparatus at present, and the flameproof apparatus of external diesel engine is big to the power loss of motor, and the equipment cost height.
Summary of the invention
The purpose of this utility model provides a kind of little to engine power loss, can reach the diesel engine flameproof apparatus of the explosion-proof criteria of national regulation again.
The purpose of this utility model is achieved in that
A kind of diesel engine flameproof apparatus, it is characterized in that: comprise radiator, radiator inleting pipe, water pump, pump water inlet, cooling water tank, connecting tube, exhaust pipe, fire resistant gate, the vent gas treatment case, equal pressing plate, branched discharge pipe, main exhaust and radiator waste pipe, cooling water tank is connected with the vent gas treatment case by connecting tube, one end of main exhaust places cooling water tank, be connected with four branched discharge pipes respectively, the other end places the vent gas treatment case, be connected with equal pressing plate, all on the pressing plate a plurality of exhaust ports are arranged, pump water inlet one end places cooling water tank, the other end is connected with pump, radiator inleting pipe one end is connected with pump, the other end is connected with radiator, one end of radiator waste pipe is connected with radiator, the other end is connected with cooling water tank, and exhaust pipe one end is connected with the vent gas treatment case, and the other end is connected with fire resistant gate.
Can be provided with baffler on the main exhaust in the vent gas treatment case.
In vent gas treatment case bottom, the main exhaust outlet port can be provided with guide plate.
Can be provided with fan on the radiator.
Fire resistant gate is combined by a plurality of corrosion resistant plates, and the gap of corrosion resistant plate is at 15～25um.
Benefit of the present utility model is:
The casing temperature that diesel engine exhaust and outlet pipe close on is no more than 105 ℃, is lower than 150 ℃ of standards of national Specification.The content of CO and NO is lower than national specified discharge standard in the tail gas.Simultaneously, the power loss of motor is less.Can be widely used in the down-hole transportation in colliery.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, a kind of diesel engine flameproof apparatus is characterized in that: comprise radiator 1, radiator inleting pipe 3, water pump 4, pump water inlet 5, cooling water tank 6, connecting tube 7, exhaust pipe 8, fire resistant gate 9, vent gas treatment case 10, equal pressing plate 13, branched discharge pipe 15, main exhaust 16 and radiator waste pipe 17.Cooling water tank 6 is connected with vent gas treatment case 10 by connecting tube 7, one end of main exhaust 16 places cooling water tank 6, be connected with four branched discharge pipes 15 respectively, the other end places vent gas treatment case 10, be connected with equal pressing plate 13, all on the pressing plate 13 a plurality of exhaust ports 18 are arranged, pump water inlet 5 one ends place cooling water tank 6, the other end is connected with pump 4, and radiator inleting pipe 3 one ends are connected with pump 4, and the other end is connected with radiator 1, one end of radiator waste pipe 17 is connected with radiator 1, the other end is connected with cooling water tank 6, and exhaust pipe 8 one ends are connected with vent gas treatment case 10, and the other end is connected with fire resistant gate 10.
Fire resistant gate 10 is combined by a plurality of corrosion resistant plates, and the gap of corrosion resistant plate is about 20um.The vent gas treatment upper box part is provided with water injection hole 11.
In vent gas treatment case 10 bottoms, main exhaust 16 outlet ports can be provided with guide plate 14, and the tail gas that main exhaust 16 is discharged evenly is drained in the vent gas treatment case 10.
Can be provided with fan 2 on the radiator 1, the cooling effect of strong radiator.
During work, radiator 1, cooling water tank 6, connecting tube 7, vent gas treatment lower box part are marked with water.
Vent gas treatment case 10 mainly plays cleaning of off-gas, and the effect of auxiliary temperature-reducing is also arranged simultaneously.Water is equipped with in the bottom of vent gas treatment case 10, and the tail gas that main exhaust 16 is discharged evenly enters in the water under the effect of guide plate 14, and produces the surge phenomenon, and most of objectionable impurities in the tail gas is washed in water.When tail gas by equal pressing plate 13 in exhaust port when making progress exhaust, produce thick fog on the top of vent gas treatment case, handle for again remaining objectionable impurities once more, make the content of CO and NO be significantly less than national specified discharge standard.
Disposed tail gas is by exhaust pipe 8, and fire resistant gate 9 enters in the atmosphere.The effect of fire resistant gate 9 is effectively to stop exhaust combustion, has further strengthened its Security.
