Description
Technical field
The utility model relates to diesel engine, is specifically related to a kind of anti-explosion diesel engine.
Background technique
Under the stringent legislation restriction of country about safety of coal mines, under the driving of the economic benefits that energy scarcity causes, relevant person more and more recognizes, the performance transformation as the anti-explosion diesel engine of one of well dynamic is more and more urgent.The use as " wasting one's talent on a petty job " of diesel engine is also no longer satisfied with in each colliery, but requires that the emission performance of the power character of diesel engine, fuel economy and tail gas reaches the performance of the diesel engine before Reformation for Explosion Proof all as far as possible, reaches corresponding NBS simultaneously.
In research and development process, researcher only considers the emission purification process of tail gas mostly, and does not have the real angle from its generation principle diesel engine to be carried out to the improvement of aspect of performance.All downhole anti-explosion diesel engines now used on the basis of normal diesel engine, remove vent systems reinstalled gas exhaust manifold with water jacket and water jacket gas exhaust pipe, adds inlet and outlet fence, bellows and waste gas treatment tank to prevent the tempering of diesel engine, after-burning, tail gas clean-up and noise elimination simultaneously.Just because of these supplementary equipment adding diesel engine, the resistance causing inlet and exhaust system increases.The diesel engine being increased in naturally aspirated of intake resistance causes the reduction of suction pressure, and the flow velocity of the later stage waste gas of exhaust phase can be lower than the flow velocity designed by former diesel engine, simultaneously at inlet and exhaust valve stacking stage, suction pressure is lower, exhaust resistance is larger, the inlet of fresh air and the discharge capacity of waste gas all less, like this after exhaust valve closing, large than designed by former diesel engine of residual waste gas quantity in cylinder, less at charging stage suction pressure, the fresh air entering cylinder is less, the volumetric efficiency of the fresh air namely in cylinder is less, causing entering cylinder oxygen tolerance deficiency like this causes the power character of diesel engine to reduce, C in tail gas, CH, the amount of CO increases, there is more imperfect combustion diesel fuel mixtures to be easy to cause after-burning in tail gas and comparatively intake manifold air pressure is larger at exhaust later stage cylinder pressure simultaneously, temperature is higher, easily cause the situation of tempering.
Summary of the invention
The utility model provides a kind of anti-explosion diesel engine to solve the problem exactly.
The technological scheme that the utility model will be dealt with problems is as follows:
A kind of anti-explosion diesel engine, comprise the air inlet system and exhaust system be connected with diesel engine, the cooling system be connected with air inlet system and exhaust system, the exhaust treatment system be simultaneously connected with cooling system and air inlet system and exhaust system and with surface temperature sensor, cooling-water temperature sensor, exhaust gas temperature sensor, the automatic the protects the monitoring system of level sensor, described gas handling system comprises air-strainer, air inlet fence and inlet flap, vent systems comprises air exhaust fence, it is characterized in that: being arranged by some fence piece forms air inlet fence or/and air exhaust fence, its fence piece suction port end is ground into ellipse or is whittled into wedge angle.
Described inlet flap controls its air door size by the fluid sensor that is connected with automatic the protects the monitoring system, and described fluid sensor is located between air inlet fence and air-strainer.By the control to its air door, reach the monolithic stability that air enters diesel engines pressure after diesel engine, to reduce the amount of C, CH, CO in tail gas after reaching Thorough combustion.
The beneficial effects of the utility model are as follows:
Compared with prior art, adopt the anti-explosion diesel engine of the utility model structure, the fence piece suction port end of the air inlet fence in air inlet system and exhaust system is worn into ellipse or is whittled into wedge angle, be conducive to the resistance that air in gas handling system enters and in vent systems, waste gas is discharged to reduce, the adverse consequences that can effectively prevent tempering from producing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of anti-explosion diesel engine of the utility model.
In figure: 1, air-strainer, 2, inlet flap, 2a, air inlet fence, 2b, air exhaust fence, 3, inlet box, 4, air inlet bellows, 5, water supply tank, 6, diesel engine, 7, constant magnetic generator of explosion-proof type, 8, radiator, 9, exhaust expansion bellows, 10, waste gas treatment tank, 11, fluid sensor.
Embodiment:
Mode of execution one, consult Fig. 1, A in figure, air flow is shown in B, C, D be depicted as into, air exhaust fence (2a, partial enlargement 2b), a kind of anti-explosion diesel engine, comprise the air inlet system and exhaust system be connected with diesel engine (6), the cooling system be connected with air inlet system and exhaust system, the exhaust treatment system be simultaneously connected with cooling system and air inlet system and exhaust system and with surface temperature sensor, cooling-water temperature sensor, exhaust gas temperature sensor, the automatic the protects the monitoring system of level sensor, automatic the protects the monitoring system also has a protection monitor, described gas handling system comprises air-strainer (1), air inlet fence (2a) and inlet flap (2) composition be arranged on inlet box (3), the side of diesel engine (6) is provided with water supply tank (5), constant magnetic generator of explosion-proof type (7) and radiator (8), and the waste gas treatment tank (10) that diesel engine (6) forms vent systems by an exhaust expansion bellows (9) and is connected, air exhaust fence (2b) is provided with between waste gas treatment tank (10) and exhaust expansion bellows (9), arranged by some fence piece and form air inlet fence (2a) or/and air exhaust fence (2b), its fence piece suction port end is ground into ellipse or is whittled into wedge angle.
Mode of execution two; based on mode of execution one; described inlet flap (2) controls its air door size by a fluid sensor be connected with automatic the protects the monitoring system (11), and described fluid sensor (11) is located between air inlet fence (2a) and air-strainer (2).
The surface temperature sensor of automatic the protects the monitoring system is arranged in diesel engine (6) is upper, cooling-water temperature sensor is arranged in water supply tank (5), exhaust gas temperature sensor is arranged on exhaust emission suction system, level sensor is arranged at waste gas treatment tank (10), the setting of these sensors with to use and of the prior art identical.
Principle of the present utility model is as follows:
The air flow of air A as shown in Figure 1, first enter air-strainer (1) to be filtered by it, and then enter inlet flap (2) through air inlet fence (2a), then whole workflow is entered successively, this workflow is same as the prior art, discharge finally by vent systems, flow through the air exhaust fence (2b) of the air flow of B as shown in Figure 1 therebetween, because entering, air exhaust fence (2a, suction port end 2b) is ground into ellipse or is whittled into wedge angle, this just makes air enter very smooth and easy and air inflow to become large to some extent, during air one-way flow, resistance reduces, the adverse consequences that cocoa effectively prevents tempering from producing.And which existing supplementary equipment inlet and outlet fence (2a, 2b) increases regardless of diesel engine all can not affect using effect to some extent.
And the uninterrupted of inlet flap (2) is entered by fluid sensor perception air; existing technical staff experience or repeatedly debugging under can draw optimized air inlet scope; simply arrange by automatic the protects the monitoring system; certainly these settings are not technical problem to be solved in the utility model; when dispatching from the factory, drawing after can being debugged by manufacturing enterprise and arranging.
