Background technique
The explosion--proof regulations regulation of China: any position of anti-explosion diesel engine surface temperature must not be above 150 ℃; The final delivery temperature of diesel engine must not be above 70 ℃.The purpose that the waste gas cooling processing device of anti-explosion diesel engine is set reaches this index exactly, and eliminates the cigarette charcoal.
The waste gas type of cooling can be divided into dry type cooling and wet type cooling, and vent systems comprises has started relief opening, pipeline, waste gas treatment case (wet type cooling), Explosion-resistant pale etc.For dry type cooling or the wet type cooling that guarantees following adopted can be cooled to waste gas below the safety temperature, it is that the pipeline that enters before dry cold radiator cooler or the wet type cooling unit is provided with water jacket that traditional way is given, or the plain tube bank cooler of an external belt water jacket is set.This kind chiller efficiency is low, volume and quality are big, dismounting is extremely inconvenient during cleaning, and summer ambient temperature than in higher, because cooling effect is undesirable, can only be with about gaseous effluent to 150 ℃, in addition higher, the exhaust gas temperature that causes entering dry cold radiator cooler or wet type cooling unit is than higher, so cause delivery temperature can near in addition be higher than 70 ℃.
Traditional cooler for recycled exhaust gas air chamber is not provided with water jacket, and the waste gas intake temperature is generally at 500 ℃--and between 800 ℃, the plenum surface temperature of inlet end can be than higher, easily to component or system impact on every side.
Summary of the invention
The purpose of this utility model provides the cooler for recycled exhaust gas of the better air chamber band jacket structure for water of a kind of radiating effect and reliability, make dry cold radiator cooler in the vent systems or wet type cooling unit more easily, more reliably waste gas is cooled to below 70 ℃ of national Abgasgesetz regulation, and self surface temperature can not surpass 150 ℃, thereby near component or system is not impacted.
The purpose of this utility model is achieved in that
A kind of cooler for recycled exhaust gas of air chamber band jacket structure for water, be fixed with the air chamber of strap clamp layer respectively at the two ends of cartridge type housing, be equipped with the water pipe adapter that is communicated with the air chamber inner chamber on each air chamber shell, be fixed with the joining plate that is evenly equipped with mounting hole on the inwall of air chamber inner casing, be provided with the cooling tube bundle of forming by some cooling tubes in the cartridge type housing, the two end part of cooling tube are fixed on the mounting hole of two joining plates, make the air chamber inner chamber and the cooling tube inner chamber of both sides form exhaust steam passage, described cooling tube is spiral pipe or spiral flat tube, cartridge type housing two ends are provided with several equally distributed water ports near the joining plate place, and the inner chamber of air chamber sandwiched formation is by water port and cartridge type housing, the inner chamber in cooling tube and joining plate besieged city is communicated with the formation flow channel.
Above-mentioned cartridge type housing is fixedlyed connected by end cap with the air chamber shell.
Above-mentioned spiral cooling tube is single head volute or multi-start helical tubes.
Adopt the arrangement of rhombus between the above-mentioned cooling tube, compact structure.
The O-ring seals sealing is adopted in the joint of above-mentioned water pipe adapter and air chamber shell.
Cooling water flows to the other end from flow channel one end, and the type of cooling can be reflux type or concurrent (with respect to the flow direction of waste gas in exhaust steam passage); Cooling tube bundle adopts the arrangement of rhombus, compact structure; The heat exchange efficiency of spiral cooling tube is very high, can reduce effectively about the exhaust gas temperature to 100 that enters before dry cold radiator cooler or the wet type cooling unit ℃, be convenient to follow-up dry cold radiator cooler or wet type cooling unit, more reliably delivery temperature be cooled to below 70 ℃ of national legislation regulation.
The utility model gives prominence to compared to existing technology and beneficial technical effects is:
1, the air chamber at cooler of the present utility model two ends is provided with interlayer, water flowing forms water jacket in the interlayer, thereby has explosion-proof function at special occasions (as the colliery), cooling water flows in the interlayer of air chamber, can make the temperature of air chamber outer surface can not be no more than 150 ℃ of national explosion--proof regulations regulation with all outer surfaces temperature of guaranteeing gaseous effluent above the temperature of cooling water.
2, cartridge type housing of the present utility model two ends are provided with several equally distributed holes, make water flow be tending towards homogenization.
3, cooling tube of the present utility model is spiral pipe or spiral flat tube, and sped structure has improved the heat exchange efficiency of cooler widely.
4, on the gas exhaust piping of the full flow that is applied in special vehicle of the present utility model or be applied in the gas recirculation system to reduce the temperature of waste gas.
