Summary of the invention
The object of the invention is to propose one and both made diesel engine surface temperature up to standard, ensure again the anti-explosion diesel engine water-cooling type exhaust gas cleaner of the transformation efficiency that DOC core body is high.
For achieving the above object, the present invention takes following technological scheme: the present invention has forward flange, rear flange, housing and DOC core body, housing has body shell and lower shell body, the front portion of body shell is the cone with suction port, the rear portion of body shell is hemisphere, body shell and lower shell body are respectively by interior, frame composition, it between inner and outer shell, is water jacket, the water jacket of body shell and the water jacket of lower shell body communicate, outer wall water inlet, lower shell body bottom place is provided with water supply connector, osculum place in the cone external wall of upper portion of body shell is provided with water output connector, described forward flange is fixed on the front end of body shell, in forward flange, be provided with heat insulation flange, the latter half of air guide sleeve that is connected with of forward flange, the rear portion of air guide sleeve is goed deep in body shell, before the inwall at body shell middle part is provided with, rear spacer ring, before DOC core body is clamped in, between rear spacer ring, before, the annulus in the DOC core body cylinder outside between rear spacer ring is air insulated district, the inner housing of lower shell body upwards extends to form honeycomb duct, honeycomb duct is provided with air outlet hole facing to the cylinder of hemisphere body lumen wall, rear flange is arranged on the lower end of lower shell body.
The external stability of described forward flange has overcoat, and the rear portion of overcoat is fixed on the cone position of main body cover.
Between end face in described body shell and in honeycomb duct and the inner roof wall of body shell, be provided with elasticity gusset.
On the outer cylinder of described DOC core body, be wrapped with the sheet iron that thickness is no more 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, avoids DOC core body directly to contact with outside water jacket, adopts air heat insulation, thereby ensures the required reaction temperature of the efficient effect of DOC core body.3, the tail gas that anti-explosion diesel engine is discharged is after air guide sleeve shunting, and uniform-flow is crossed whole DOC core body, and DOC core body is heated evenly, and has improved DOC core body catalyst activity position utilization ratio, the favourable prolongation DOC core body life-span.4, arranging of spacer ring can be avoided causing housing cracking because DOC core body expands.5, because body shell rear portion is hemisphere, rear chamber is sphere chamber, can make the tail gas of flowing through after DOC core body after the refraction of hemisphere body lumen wall, flow into honeycomb duct discharge, this device smooth gas discharge.6, heat insulation flange is installed at the suction port place of body shell, can avoid high-temperature tail gas directly to impact forward flange, makes forward flange place surface temperature meet the requirement of peace mark.
