Abstract
The utility model relates to a heat isolation energy-saving silencer for an engine. The heat isolation energy-saving silencer for an engine is mainly composed of an air outlet pipe, an air inlet pipe, an air inlet port, an air outlet port and a heat isolation cover. The air outlet pipe and the air inlet pipe are arranged side by side. The heat isolation cover is respectively arranged on the outer faces of the air outlet pipe and the air inlet pipe. Compared with the prior art, the heat isolation energy-saving silencer for an engine has the advantages of heat isolation, sound isolation, energy saving, enhancement of engine power, decrease of fuel consumption, improvement of the working environment for operators, etc.
Description
The utility model relates to a kind of muffler for motor, specifically a kind of marine engine heat-insulating and energy-saving silencing apparatus.
Mostly existing marine engine is high-powered engine, is installed in the cabin of bottom, ship storehouse.Its outlet pipe generally all is to be directly exposed in the air, allow the heat nature in air, distribute, temperature in the cabin is along with the prolongation of engine operating duration can improve constantly like this, the summer of especially tight heat, the very severe that the working environment of cabin can become has a strong impact on health of operators.
The purpose of this utility model provides a kind of exhaust waste heat that makes full use of, and saves energy and reduce the cost and reduces noise, effectively improves the motor heat-insulating and energy-saving silencing apparatus of working environment.
The purpose of this utility model realizes in the following manner, the row's inlet pipe and the suction tude of motor are installed together side by side, add the noise elimination thermal shield in its outside, allow the air of heat heating air inlet pipe of outlet pipe to improve the temperature of engine charge, the temperature that has so promptly reduced exhaust has improved the temperature of air inlet, can also improve the pollution of the power of motor, the consumption that reduces fuel oil and minimizing noise.
Figure of description 1 is that the utility model A-A is to cross sectional view;
Illustrate that accompanying drawing 2 is lateral plan of the present utility model;
Illustrate that accompanying drawing 3 is plan view of the present utility model.
Explain below with reference to Figure of description the utility model being done.
Heat isolation energy-saving silencer for engine of the present utility model, partly formed by blast pipe (1), air inlet pipe (2), exhaust outlet (4), air inlet (3) and heat shield etc., blast pipe (1) and air inlet pipe (2) are installed together side by side, and heat shield is installed in the outside of blast pipe (1) and air inlet pipe (2).
Have at least 2 relief openings (4) to be installed on the outlet pipe (1), have at least 2 suction ports (3) to be installed on the suction tude (2), the end of relief opening (4) and suction port (3) is welded with flange plate (8), relief opening (4) and suction port (3) and is spaced on same center line.
Thermal shield is made up of inner casing (5) shell (7) and thermal-protective material (6), and thermal-protective material (6) is filled between inner casing (5) shell (7).Inner casing (5) shell (7) is to be made by sheetmetal such as iron plate or aluminium sheet, and thermal-protective material (6) is to be made by magnesium steel or heat-resistant materials such as mineral wool, glass fibre.
Embodiment: motor heat-insulating and energy-saving silencing apparatus of the present utility model, be mainly used on the marine engine, existing marine engine generally is a multicylinder engine, the cylinder number is between 2-6, shown in the Figure of description is the silencing apparatus that is used for 6 Cylinder engines, relief opening is installed on the outlet pipe, suction port is installed on the suction tude, between the two every being arranged on the same center line, the inside and outside shell of thermal shield, be to make with tinplate, the centre is filled with thermal-protective materials such as magnesium steel, thermal shield is wrapped in the outside of outlet pipe and suction tude, waste gas scorching hot during engine operation enters outlet pipe from relief opening, because outlet pipe and suction tude are installed in the thermal shield side by side, the used heat of outlet pipe is absorbed by suction tude, and air is heated in suction tude, enter motor by suction port, therefore can improve the power that starts and reduce fuel consume, prevent that effectively used heat from distributing and the width of cloth is penetrated in cabin, can also reduce noise effectively simultaneously.Pollution to the cabin environment.By evidence, silencing apparatus of the present utility model is installed on existing marine engine, continuous firing 500 hours, the surface temperature of silencing apparatus has only 80 ℃, and makes noise reduce more than 5 one-tenth.And the surface temperature of common exhaust duct is 500 ℃.
Heat isolation energy-saving silencer for engine of the present utility model is compared with existing technology has the Waste Heat Recovery utilization, improve engine power, reduce fuel oil consumption, reduce engine waste heat and noise to the advantages such as pollution of cabin environment, extensively promote the use of and to have good economic results in society.
Claims (3)
1, motor heat-insulating and energy-saving silencing apparatus comprises that outlet pipe, suction tude, relief opening, suction port and thermal shield etc. partly form, and it is characterized in that outlet pipe and suction tude are installed together side by side, and thermal shield is installed in the outside of outlet pipe and suction tude.
2, silencing apparatus according to claim 1 is characterized in that having at least 2 relief openings to be installed on the outlet pipe, has at least 2 suction ports to be installed on the suction tude, and suction port and relief opening are spaced on same center line.
