Abstract
The utility model relates to an exhaust pipe, in particular to a cooling exhaust pipe, and the exhaust pipe solves the problems of restricted exhaust and easy reduction of diesel engine power of the existing exhaust pipe. The exhaust pipe is provided with a medial wall which is attached to an external end face of a mouth part of a gas outlet on a diesel engine body. The medial wall is provided with a gas inlet hole which is corresponding to the gas outlet on the diesel engine body, a lateral wall of the exhaust pipe is arranged opposite to the medial wall, and is provided with an exhaust hole. The medial wall and the lateral wall enclose each other to form an exhaust channel, and are both composed of an inner plate and an outer plate with a double-layer structure of cooled water in an interlayer. The medial wall and the lateral wall are both provided with a flow guide structure. The lateral wall is in the shape of slope or arc which guides waste gas flow toward the exhaust hole. A position of the inner plate of the medial wall which is close to the exhaust hole is in the shape of slope or arc which is convenient for waste gas to flow through. A gas guide plate which extends to the exhaust hole from the medial wall to avoid collision of gas flows is arranged on a position on the medial wall opposite to the exhaust hole.
Description
Technical field
The utility model relates to a kind of outlet pipe, especially a kind of cooled exhaust pipe.
Background technique
The exhaust gas temperature of discharging during the diesel engine acting is up to 650 ℃, if diesel applications is in inflammable and explosive occasion, then to carry out explosion-proof processing to this, and any appearance temperature of flame proof technical requirements flameproof apparatus can not be greater than 150 ℃, delivery temperature is less than 70 ℃, this has particular structure with regard to the outlet pipe that requires diesel engine, and the one, spacer structure, two will use water cooling.
What explosion-proof exhausting pipe extensively adopted at present all is to be similar to the structure shown in the accompanying drawing 1 to 3, ventilation in the interior pipe, water flowing cooling between interior pipe and the outer tube, waste gas is introduced the waste water treatment case from flange and is cooled off once more and remove contamination, and the defective of this design is: be not provided for the device that direct exhaust flows in the exhaust passage, exhaust flow does not have the guiding of air-guide device, outlet pipe adopts square setting in addition, waste gas causes eddy current easily in outlet pipe, strengthened gas-flow resistance, has increased the power loss of diesel engine.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of novel cooled exhaust pipe is provided, and overcoming existing outlet pipe does not have the exhaust flow air-guide device, and gas-flow resistance is big, can cause the big defective of power loss of diesel engine.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of cooled exhaust pipe, outlet pipe have with diesel-engine body on oral area exterior edge face, the air outlet madial wall of fitting, madial wall be provided with diesel-engine body on the corresponding inlet hole in air outlet, relative with madial wall is the outer side wall of outlet pipe, has exhaust port on the outer side wall, madial wall and outer side wall closure form the exhaust passage, described inlet hole communicates with the exhaust passage, in madial wall and outer side wall are all served as reasons, lamina rara externa is formed, the double layer construction of logical cooling water in the interlayer, described madial wall and outer side wall have flow guide structure.
Specifically: the flow guide structure of described madial wall and outer side wall is: outer side wall is the oblique or arc that direct exhaust flows to exhaust port; Inner plating on the madial wall is the oblique or arc that makes things convenient for exhaust flow to cross with inlet hole mutually nearby.
Again specifically: the position relative with exhaust port on the described madial wall is provided with the aeroscopic plate of avoiding air-flow to bump against that stretches to exhaust port from madial wall.
The beneficial effects of the utility model are, a kind of novel cooled exhaust pipe of the present utility model has waste gas flow guide structure and exhaust flow air-guide device, and gas-flow resistance is little, and the power loss of diesel engine is little.
