Abstract
The invention relates to self-regulated exhaust and explosion protection equipment of a mining diesel engine. The self-regulated exhaust and explosion protection equipment comprises a front exhaust duct, a cooking water jacket, a rear exhaust duct and an expansion waste gas tank, wherein the cooling water jacket is arranged outside the front exhaust duct, the rear exhaust duct and the expansion waste gas tank, the front exhaust duct and the rear exhaust duct are respectively arranged at two ends of the expansion waste gas tank, an unburned material particle cleaning-up hole is arranged at the lower end of the expansion waste gas tank, a fence explosion protection structure is arranged in the expansion waste gas tank, and a temperature sensor is arranged at the rear exhaust duct and connected with an electronic control unit (ECU) by a lead. The self-regulated exhaust and explosion protection equipment can achieve the purpose of regulating flow velocity of cooling water along with working conditions by adopting combined exhaust and cooling technology and controlling the flow velocity of the cooling water by connecting the temperature sensor with the ECU, and ensure the temperature of exhausted waste gas to be always under 70 DEG C in running; and in addition, the waste gas expansion structure can effectively reduce the flow velocity of the waste gas, and fuel particles with sparks in the waste gas cab be collided with the waste gas due to the fence structure, thus achieving the effect of eliminating sparks.
Description
Technical field
The present invention relates to a kind of mining diesel engine flameproof apparatus, especially relate to a kind of mining diesel engine self-regulation exhaust explosion-proof device.
Background technique
Inflammable and explosive working environment requires to have explosion-proof performance usually to some electromechanical equipments under the mine, could guarantee that it normally, move safely.Diesel engine in running, with producing and discharge a large amount of waste gas, these high-temp waste gas mine methane gas down that both ignited easily, the damage engine components pollute the environment again, so must handle waste gas.The EGT of discharging when mining diesel engine does work generally is higher than 400 ℃, and any hull-skin temperature of explosion-proof technology requirement flameproof apparatus can not be greater than 150 ℃, and delivery temperature is less than 70 ℃.Existing anti-explosion diesel engine for mine exhaust technique generally is through using common recirculated cooling water, at air flue outer cover last layer water channel, to reach cooling effect.For the work under the diesel engine different capacity; This cooling technology lacks consistency strategy, keeps for a long time at diesel engine under the condition of high-power operating mode, and cooling water temperature can rise to more than 90 ℃ very soon; This will cause the EGT of its discharge to rise to more than 70 ℃; Surpass below 70 ℃ of explosion-proof technology standard-required, functional reliability is relatively poor, has potential safety hazard.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the above-mentioned defective that existing technology exists, and provides a kind of functional reliability high, the mining diesel engine self-regulation exhaust explosion-proof device that Safety performance is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mining diesel engine self-regulation exhaust explosion-proof device; Comprise front-seat air flue, cooling jacket, final vacuum road, expansion waste heat box; It is outside that cooling jacket is located at front-seat air flue, final vacuum road and expansion waste heat box; Expansion waste heat box two ends are located in front-seat air flue and final vacuum road respectively, and expansion waste heat box lower end has unburning material clearance of particles mouth, and the fence blasting resistance structure is housed in the expansion waste heat box; Place, final vacuum road is provided with temperature transducer, and temperature transducer links to each other with electronic control unit (ECU) through lead-in wire.
Further, be provided with sealing bolt in the said unburning material clearance of particles mouth.
The present invention adopts combined type exhaust cooling technology, utilizes temperature transducer to connect the flow velocity of ECU control cooling water, thereby reaches the purpose with regulating working conditions cooling water flow velocity, and when guaranteeing operation, the EGT of its discharge is all the time below 70 ℃; Simultaneously, the waste expansion structure can reduce the waste gas flow velocity effectively, and fence structure makes the fuel particle that has spark in the waste gas collide with it, reaches the effect of arc control.
Use the present invention, anti-explosion diesel engine for mine work is more reliable, moves safer.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
With reference to Fig. 1; Present embodiment comprises front-seat air flue 1, cooling jacket 2, final vacuum road 9, expansion waste heat box 5; Cooling jacket 2 is located at front-seat air flue 1, final vacuum road 9 and expansion waste heat box 5 outsides; Front-seat air flue 1 is located at expansion waste heat box 5 two ends respectively with final vacuum road 9, and expansion waste heat box 5 lower ends have unburning material clearance of particles mouth 10, and fence blasting resistance structure 6 is housed in the expansion waste heat box 5; 9 places, final vacuum road are provided with temperature transducer 7, and temperature transducer 7 links to each other with electronic control unit (ECU) through lead-in wire 8.
Be provided with sealing bolt 11 in the unburning material clearance of particles mouth 10.
Diesel exhaust gets into this exhaust explosion-proof device by front-seat air flue 1, then gets in the expansion waste heat box 5, is flow in the surrounding environment by final vacuum road 9.Cooling water flows into whole water jacket 2 by water jacket inlet 2-1, and whole exhaust explosion-proof device is cooled off.Waste gas gets into expansion waste heat box 5 back flow velocitys to be reduced, and elongated 6 times of contact with the fence blasting resistance structure, inflammable matter particle that does not extinguish and 6 collisions of fence blasting resistance structure are extinguished Mars.When the EGT of temperature transducer 7 was moderate if flow through, when promptly diesel engine was with low-power operation, temperature transducer 7 was through 8 pairs of ECU output of lead-in wire normal signal, and the cooling water flow velocity in the water jacket 2 remains unchanged.
When the EGT of temperature transducer 7 was too high if flow through, when promptly diesel engine was with high-power operation, temperature transducer 7 was through 8 pairs of ECU output abnormality signals of lead-in wire, and the control cooling water is accelerated flow velocity, reaches the effect that strengthens the cooling dynamics.Fence blasting resistance structure 6 can intercept part combustion gas particle, causes the unburning material particle packing, at this moment, can be through dismantling lower seal bolt 11, the unburning material particle that realization is piled up never fires composition granule removes mouthful 10 places removing totally.
Evidence: adopt anti-explosion diesel engine for mine of the present invention, during operation, the EGT of its discharge is all the time below 70 ℃; Simultaneously, there is not spark to produce yet.
