Abstract

The utility model discloses a diesel engine exhaust waste heat utilization system with oxygenated fuel serving as a heat absorption carrier, which belongs to the technical field of energy conservation and emission reduction of combustion of the diesel engine and comprises a combustion chamber, an air inlet pipe, a heat exchanger and an exhaust pipe. The air inlet pipe is communicated with the combustion chamber and the heat exchanger through a pipeline. Another pipeline of the combustion chamber is communicated with the heat exchanger. The exhaust pipe is arranged at the tail end of the heat exchanger. The diesel engine exhaust waste heat utilization system with the oxygenated fuel serving as the heat absorption carrier requires no additional energy supply to achieve decomposition of the oxygenated fuel. In addition, the purpose of energy conservation and emission reduction can be achieved by mixing the decomposed mixed gas of the oxygenated fuel to the combustion chamber of the diesel engine to participate in combustion.

A kind of oxygenated fuel is the diesel engine vent gas bootstrap system of heat absorption carrier, and this system is made up of firing chamber 1, suction tude 2, heat exchanger 3 and outlet pipe 4; Suction tude 2 communicates with firing chamber 1 and heat exchanger 3 through pipeline; Another pipeline of firing chamber 1 communicates with heat exchanger 3; Outlet pipe 4 is installed in heat exchanger 3 ends.
Said heat exchanger 3 comprises interior pipe, outer tube and at least one baffle plate, and interior pipe is many flat copper tube banks, and outer tube wall is a stainless steel.
Heat exchanger 3 is small-sized efficient heat exchanger or small-sized catalytic reactor.
The beneficial effect of the utility model: system of the present invention need not outside extra energy supply, just can realize the decomposition of oxygenated fuel, and it decomposes mixed gas entering burning chamber of diesel engine participation burning through blending, reaches the purpose of energy-saving and emission-reduction.Through diesel oil and oxygenated fuel addition Coupling Control, can be applied to modern automobile-used, generating with on the diesel engine.
Description of drawings
Fig. 1 is the diesel engine vent gas bootstrap system schematic representation of oxygenated fuel for the heat absorption carrier;
Among the figure, 1-firing chamber, 2-suction tude, 3-heat exchanger, 4-outlet pipe, 5-high-temperature tail gas, 6-oxygenated fuel.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
A kind of oxygenated fuel is the diesel engine vent gas bootstrap system of heat absorption carrier, and as shown in Figure 1, this system is made up of firing chamber 1, suction tude 2, heat exchanger 3 and outlet pipe 4; Suction tude 2 communicates with firing chamber 1 and heat exchanger 3 through pipeline; Another pipeline of firing chamber 1 communicates with heat exchanger 3; Outlet pipe 4 is installed in heat exchanger 3 ends; Heat exchanger 3 comprises interior pipe, outer tube and at least one baffle plate, and interior pipe is many flat copper tube banks, and outer tube wall is a stainless steel; Heat exchanger 3 is small-sized efficient heat exchanger or small-sized catalytic reactor.
The working procedure of this system is: diesel engine starting, and after the stable operation, oxygenated fuel 6 is through heat exchanger 3; Absorb the heat of outlet pipe 4 tail gas of diesel engine, high temperature condition bottom or all decomposition, the mixed gas of little molecular carbon hydrogen compounds such as generation hydrogen, carbon monoxide, methane; Mixed gas is through behind the heat exchanger 3; Feed the suction tude 2 and the air mixing of diesel engine, get into firing chamber 1 then and participate in burning, thereby improve the combustion process of firing chamber 1; Improve burning quality, reduce the discharging of pollutants such as soot, NOx.Simultaneously, high-temperature tail gas 5 is through behind the heat exchanger 3, and temperature descends, and realizes the heat recovery and the utilization of diesel smoke.
Under the low loading condition of diesel engine, temperature of exhaust fume is low, and under the high load condition, temperature of exhaust fume is high.Therefore, in actual application, can realize optimal operating condition, guarantee the stable operation of diesel engine through the Coupling Control of diesel oil and oxygenated fuel addition.
