Technical field
The present invention relates to anti-explosion diesel engine water-cooling type exhaust gas cleaner.
Background technology
In underground coal mine machinery, anti-explosion diesel engine is wherein main a kind of power source.Anti-explosion diesel engine uses the particularity of environment due to it, causes that its emission level lags far behind normal diesel engine.Under mine, by the restriction of dash condition, the harmful gas that anti-explosion diesel engine is discharged can not spread timely so that tunnel air quality continuous decrease, and under serious harm ore deposit, staff's is healthy.China Patent No. be 200920103426.4 utility model patent disclose a kind of purifier for explosionproof diesel engine offgas, high temperature resistant heat insulation coating layer all it is coated with including outside the shell being made up of upper shell and lower house and oxidized form catalytic cleaner core body (DOC) being placed in shell, upper shell and lower house inwall and oxidized form catalytic cleaner core body；Upper shell and lower house two ends are respectively provided with ring flange, and the ring flange between upper shell with lower house is connected composition surface and sets up sealing gasket.China Patent No. be 200920093082.3 utility model patent disclose a kind of exhaust purification device for mining explosion-proof diesel, depurator core body it is provided with in insulated case, insulated case adopts Flange joint with hood, described depurator core body, adopt the precious metal material such as platinum, rhodium to make catalyst, under mesophilic condition the hydrocarbon in tail gas, oxygen are carried out chemical reaction, eliminate nuisance, to reduce the discharge of cigarette, dirt nuisance, tail gas is made to be purified.For anti-explosion diesel engine, it is desirable to surface temperature is less than 150 DEG C, and will not ignite fuel gas, so needing to take measures to control diesel engine surface temperature.But oxidized form catalytic cleaner core body temperature must reach reaction temperature, transformation efficiency otherwise can be affected.
Summary of the invention
It is an object of the invention to propose one had both made diesel engine surface temperature up to standard, ensured again the anti-explosion diesel engine water-cooling type exhaust gas cleaner of the transformation efficiency that DOC core body is high.
nullFor reaching above-mentioned purpose，The present invention adopts the following technical scheme that: the present invention has forward flange、Rear flange、Housing and DOC core body，Housing has body shell and lower house，The front portion of body shell is the cone with air inlet，The rear portion of body shell is hemisphere，Body shell and lower house are respectively by interior、Shell body forms，It it is water jacket between inner and outer shell，The water jacket of body shell and the water jacket of lower house communicate，Outer wall inlet opening, lower house bottom place is provided with water supply connector，Apopore place in the cone external wall of upper portion of body shell is provided with water out adapter，Described forward flange is fixed on the front end of body shell，Forward flange is provided with heat insulation flange，The latter half of of forward flange is connected to kuppe，The rear portion of kuppe is goed deep in body shell，Before inwall in the middle part of body shell is provided with、Rear spacer ring，Before DOC core body is clamped in、Between rear spacer ring，Before、The annulus outside DOC core body cylinder between rear spacer ring is air insulated district，The inner housing of lower house upwardly extends formation mozzle，Mozzle is provided with venthole facing to the cylinder of hemisphere cavity wall，Rear flange is arranged on the lower end of lower house.
The external stability of described forward flange has overcoat, and the rear portion of overcoat is fixed on the cone position of body shell.
Described body shell is interior and is between the end face of mozzle and the inner roof wall of body shell and is provided with elastic gusset.
The outer cylinder of described DOC core body is wrapped with the thickness sheet iron less than 1.8mm.
The present invention has following good effect: 1, the present invention arranges water jacket, reduces diesel engine surface temperature, makes diesel engine surface temperature up to standard.2, the present invention utilizes spacer ring to fix DOC core body, it is to avoid DOC core body directly contacts with outside water jacket, adopts air heat insulation, thus ensureing that DOC core body efficiently acts on required reaction temperature.3, the tail gas that anti-explosion diesel engine is discharged is after kuppe taps, and flows uniformly through whole DOC core body, and DOC core body is heated evenly, and improves DOC core body catalyst activity position utilization rate, the favourable prolongation DOC core body life-span.4, the setting of spacer ring is avoided that and causes housing to ftracture because DOC core body expands.5, owing to body shell rear portion is hemisphere, rear chamber is spherical cavity, can flow through the tail gas after DOC core body and flow into mozzle discharge, this device smooth gas discharge after the refraction of hemisphere cavity wall.6, heat insulation flange is installed at the air inlet place of body shell, it is possible to avoid high-temperature tail gas directly to impact forward flange, makes forward flange place surface temperature meet peace mark requirement.
