The exhaust device of the explosion-proof diesel engine comprises a water-cooled exhaust pipe, a waste gas treatment box, a particle filter and a fire arrester, wherein the particle filter and the fire arrester are arranged on the top of the waste gas treatment box in sequence; the exhaust device of the explosion-proof diesel engine is characterized in that the water-cooled exhaust pipe is of an expansion pipe structure; a water-cooled elbow is fixedly arranged on the outlet end of the water-cooled exhaust pipe through a flange; the other end of the water-cooled elbow is fixedly arranged at the lower part of the waste gas treatment box through a flange; cooling pipes are distributed in the waste gas treatment box; and both ends of the cooling pipes are communicated with a coolant box. The exhaust device of the explosion-proof diesel engine has the characteristics of ingenious idea, reasonable design and simple structure, not only can meet the exhausting, heat dissipation and cooling requirements of the diesel engine, but also does not consume the coolant, and does not have any exhaust backpressure and power loss.
Description
Technical field
The utility model belongs to the anti-explosion diesel engine field, is specifically related to a kind of anti-explosion diesel engine venting gas appliance.
Background technique
According to the pertinent regulations of coal production safety standard, apply to the diesel engine of mine, surface temperature can not surpass 150 ℃, and the temperature of discharging gas can not be above 70 ℃.In order to reach requirement, must take some cooling methods to the outlet pipe of diesel engine.As the elementary cooling of outlet pipe and waste gas washing cooling way of combining, reach the temperature that reduces exhausting air.The sandwich-type outlet pipe is all adopted in elementary cooling, also is water-cooling exhaust pipe, and it injects flowing water in interlayer, to reduce the outlet pipe surface temperature.
The measure of at present general cooled gas is to use WATER-WASHING METHOD to guarantee that delivery temperature meets the demands.There is the problem that obviously increases car weight and increase exhaust back pressure in this method, simultaneously this method cooling water of capacity that also needs often to annotate.As patent No. CN201546789U, a kind of anti-explosion diesel engine tail gas by name disappears and fires and purification plant, and patent No. CN201738994U, twin-tub anti-explosion diesel engine by name is the temperature that WATER-WASHING METHOD reduces tail gas, and this scheme deficiency water tank is a closure, if waterbox design is big inadequately, cooling water is in the process of working continuously, and water temperature constantly rises, and then influences the performance of tail gas cooling.How to improve the deficiency of WATER-WASHING METHOD, become the present problem that needs solution.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of anti-explosion diesel engine venting gas appliance at above-mentioned prior art, and it can cooled exhaust air, allows the waste gas discharge temperature reach requirement; Without the mode of wet type washing cooling, need not to be equipped with water supply tank simultaneously, alleviate complete vehicle weight; Because waste gas need not can discharge through washing, can also reduce the loss of exhaust back pressure.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of anti-explosion diesel engine venting gas appliance, include water-cooling exhaust pipe, waste gas treatment case, particle trapper and flame trap, wherein, the waste gas treatment box top is installed particle trapper and flame trap successively, it is characterized in that water-cooling exhaust pipe is the expansion tube structure, its outlet end fixedly has a water-cooled bend pipe by flange, the water-cooled bend pipe the other end is fixed on the bottom of waste gas treatment case by flange, be distributed with cooling tube in the described waste gas treatment case, the cooling tube two ends are communicated with tank for coolant.
Described water-cooling exhaust pipe forms two sections expansion tube structures for having two wide diameter portions.Adopt two wide diameter portions both can improve the rigidity intensity of outlet pipe, can make the high-temperature exhaust air instantaneous expansion again, produce heat and discharge, and reduce the temperature of tail gas.
Perhaps described water-cooling exhaust pipe is the taper expansion tube structure that enlarges gradually.
Described cooling tube is circuitous to be evenly distributed in the waste gas treatment case, and the cooling tube surface has radiating fin, to increase heat exchange area.
The beneficial effects of the utility model are: have be skillfully constructed, reasonable in design, characteristic of simple structure; Can reach the requirement of diesel exhaust gas radiating and cooling, not have coolant consumption again, no exhaust back pressure inactivity loss.
Description of drawings
Fig. 1 generalized section of the present utility model.
Embodiment
Below in conjunction with the specific embodiments and the drawings example the utility model is described further, but this explanation can not constitute restriction of the present utility model.
With reference to Fig. 1, the anti-explosion diesel engine venting gas appliance includes water-cooling exhaust pipe 1, water-cooled bend pipe 2, waste gas treatment case 3, particle trapper 4 and flame trap 5, and wherein, the waste gas treatment box top is installed particle trapper 4 and flame trap 5 successively; Described water-cooling exhaust pipe 1 is the expansion tube structure, can adopt following two kinds of structures: one, water-cooling exhaust pipe 1 have two wide diameter portions 11, form two sections expansion tube structures, as graph structure, two place's wide diameter portions 11 can increase the intensity of water-cooling exhaust pipe 1, and instantaneous expansion also can improve heat release; Two, water-cooling exhaust pipe 1 is the taper expansion tube structure that enlarges gradually, also bell mouth shape, can improve hot release equally.
Outlet end at water-cooling exhaust pipe 1 fixedly has a water-cooled bend pipe 2 by flange 12, and water-cooled bend pipe 2 the other ends are fixed on the bottom of waste gas treatment case 3 by flange 12, so that hot exhaust gas is up walked from waste gas treatment case 3 bottoms; Be distributed with cooling tube 31 in the waste gas treatment case 3, cooling tube 31 circuitous being evenly distributed in the waste gas treatment case 3, cooling tube 31 surfaces have radiating fin 32, and the exchange area of increase and hot exhaust gas improves heat exchange efficiency; Described cooling tube 31 two ends are communicated with tank for coolant.
Water-cooling exhaust pipe 1 described above and water-cooled bend pipe 2 are the interlayer sleeve pipe, inject flowing water in interlayer, and surface cooling action is provided.
