Abstract
The utility model relates to a kind of heat exchanger.Specifically, be the heat exchanger utilizing the high-temp waste gas of discharging in diesel engine running to heat cold water.It comprises cylindrical shell, and there is gas approach one end of cylindrical shell, and the other end has exhanst gas outlet.Have coil pipe in described cylindrical shell, the barrel of cylindrical shell has two pores, coil pipe two ends are stretched out from this two pore respectively, and coordinate in sealing shape between coil pipe with described pore.Mars is had to extinguish mechanism in the cylindrical shell being characterized in contiguous exhanst gas outlet one end.Adopt this heat exchanger to heat the heating agent (water or conduction oil) in fuel system, can hidden danger be eliminated.
Description
Technical field
The utility model relates to a kind of heat exchanger, specifically, is the heat exchanger utilizing the high-temp waste gas of discharging in diesel engine running to heat cold water.
Background technology
At present, in diesel fuel system, heat exchanger is mostly adopted to heat heating agent (water or conduction oil), then by heating agent by temperature extremely certain for the fuel Heating in each Oil Tank in fuel system, thus make fuel oil have mobility.Heat exchanger is wherein traditional heat exchangers, and this heat exchanger only has the coil pipe in cylindrical shell and cylindrical shell to form.In use procedure, that discharges from diesel engine discharges from the exhanst gas outlet of cylindrical shell through after entire body with the high-temp waste gas of Mars, because this heat exchanger only has the coil pipe in cylindrical shell and cylindrical shell to form, measure is extinguished without Mars, make the flue gas of discharging from exhanst gas outlet still with Mars, there is hidden danger, very dangerous.
Utility model content
Problem to be solved in the utility model is to provide a kind of heat exchanger, adopts this heat exchanger to heat the heating agent (water or conduction oil) in fuel system, can eliminate hidden danger.
For solving the problem, take following scheme:
Heat exchanger of the present utility model comprises cylindrical shell, and there is gas approach one end of cylindrical shell, and the other end has exhanst gas outlet.Have coil pipe in described cylindrical shell, the barrel of cylindrical shell has two pores, coil pipe two ends are stretched out from this two pore respectively, and coordinate in sealing shape between coil pipe with described pore.Mars is had to extinguish mechanism in the cylindrical shell being characterized in contiguous exhanst gas outlet one end.
Wherein, described Mars extinguishes mechanism and comprises a short cylinder, the external diameter of described short cylinder and the internal diameter of described cylindrical shell suitable, have composite steel wire gauze filter in short cylinder, the wire side of described filter screen and the axial vertical of short cylinder.
Leave spacing between cylindrical shell one end of contiguous exhanst gas outlet and described coil pipe, described Mars extinguishes mechanism and is in this spacing.
The two ends of described cylindrical shell are all connected with flange.
The inwall of described cylindrical shell there is heat-insulation layer.
Take such scheme, have the following advantages:
Mechanism is extinguished because the utility model is provided with Mars in the cylindrical shell of contiguous exhanst gas outlet one end.Extinguish mechanism by this Mars, the Mars in high-temperature flue gas can be extinguished in cylindrical shell, make the flue gas of discharging from exhanst gas outlet not containing Mars, thus eliminate hidden danger.
Accompanying drawing explanation
Fig. 1 is heat exchanger structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, heat exchanger of the present utility model comprises cylindrical shell 3, and gas approach 1 is left in one end of cylindrical shell 3, and the other end leaves exhanst gas outlet 7.Be provided with coil pipe 5 in cylindrical shell 3, the barrel of cylindrical shell 3 be processed with two pores, coil pipe 5 two ends are stretched out respectively in this two pore, and coordinate in sealing shape between coil pipe 5 with described pore.
Due in the high-temperature flue gas that diesel engine is got rid of with Mars, should with high-temperature flue gas of Mars by after cylindrical shell 3 still with Mars.For eliminating hidden danger, in cylindrical shell 3 one end of contiguous gas approach 1, being provided with Mars extinguishing mechanism.For ease of the installation of Mars fire suppression mechanism, between cylindrical shell 3 one end and described coil pipe 5 of contiguous gas approach 1, leave spacing, described Mars extinguishes mechanism and is in this spacing.Mars wherein extinguishes mechanism and comprises a short cylinder 4, the external diameter of described short cylinder 4 and the internal diameter of described cylindrical shell 3 suitable, be provided with composite steel wire gauze filter 8 in short cylinder 4, the wire side of described Steel net 8 and the axial vertical of short cylinder 4.Like this, when flue gas passes through the Steel net 8 in short cylinder 4, can extinguish when the Mars in flue gas encounters Steel net.
For avoiding heat to scatter and disappear along barrel, the inwall of described cylindrical shell 3 is provided with one layer of heat preservation layer 6.
For ease of matching with the exhanst gas outlet 7 of diesel engine and blast pipe under using state, at the two ends of described cylindrical shell 3, flange 2 is all installed.
During use, cylindrical shell 3 one end is connected with the flue gas exhaust pipe of diesel engine with bolt by flange 2, and the other end of cylindrical shell 3 is connected with the flue gas exhaust pipe to atmospheric exhaust.The two ends of coil pipe 5 are connected on by valve and pipeline on the heating agent closed circuit of oil conservater, precipitation Oil Tank, daytank or oil supply unit and so on respectively.
