Description
Technical field
The utility model relates to a kind of mining diesel engine flameproof apparatus, especially relates to a kind of mining diesel engine Combined exhaust air flameproof apparatus.
Background technique
Inflammable and explosive working environment requires to have explosion-proof performance usually to some electromechanical equipments under the mine, guarantee its normally, safely operation.Diesel engine will produce and discharge a large amount of waste gas in running, these high-temp waste gas methane gas under the mine that both easily ignited damages engine components, pollutes the environment again, therefore must process waste gas.The exhaust gas temperature of discharging during the mining diesel engine acting 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 by 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, keep for a long time at diesel engine under the condition of high-power operating mode, cooling water temperature can rise to more than 90 ℃ very soon, this will cause the exhaust gas temperature 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.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of functional reliability high, the mining diesel engine Combined exhaust air flameproof apparatus that Safety performance is good.
The technological scheme that its technical problem that solves the utility model adopts is: mining diesel engine Combined exhaust air flameproof apparatus, 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 at respectively in front-seat air flue and final vacuum road, expansion waste heat box lower end has unburning material clearance of particles mouth, 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) by lead-in wire.
Further, be provided with sealing bolt in the described unburning material clearance of particles mouth.
The utility model adopts the Combined exhaust air 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 exhaust gas temperature of its discharge is all the time below 70 ℃; Simultaneously, the waste expansion structure can reduce the waste gas flow velocity effectively, fence structure so that in the waste gas fuel particle with spark collide with it, reach the effect of arc control.
Use the utility model, anti-explosion diesel engine for mine work is more reliable, moves safer.
Description of drawings
Fig. 1 is the utility model one embodiment's structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, the 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, expansion waste heat box 5 two ends are located at respectively in front-seat air flue 1 and final vacuum road 9, expansion waste heat box 5 lower ends have unburning material clearance of particles mouth 10, 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) by lead-in wire 8.
Be provided with sealing bolt 11 in the unburning material clearance of particles mouth 10.
Diesel exhaust enters this exhaust explosion-proof device by front-seat air flue 1, then enters 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 entrance 2-1, and whole exhaust explosion-proof device is cooled off.Waste gas enters expansion waste heat box 5 rear flow velocitys to be reduced, elongated 6 times of contact with the fence blasting resistance structure, and the inflammable matter particle that does not extinguish and 6 collisions of fence blasting resistance structure are extinguished Mars.When the exhaust gas temperature of temperature transducer 7 was moderate if flow through, when namely diesel engine was with low-power operation, temperature transducer 7 was by 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 exhaust gas temperature of temperature transducer 7 was too high if flow through, when namely diesel engine was with high-power operation, temperature transducer 7 was by 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 by 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 utility model, during operation, the exhaust gas temperature of its discharge is all the time below 70 ℃; Simultaneously, there is not spark to produce yet.
