Abstract
A 2.5KW universal gasoline engine muffler with a two-way catalyst filter comprises a front end cover, a shell body, a back end cover and an air inlet pipe. Therein, three chambers are separated by two baffles inside the shell body, and an air outlet pipe, which is communicated with the three chambers is mounted in the shell body. The muffler is characterized in that a catalyzing filter mechanism is mounted on the air inlet pipe, the catalyzing filter mechanism is a two-way catalyst honeycomb structural body, one end of the honeycomb structural body is supported on the baffle, and the other end of the honeycomb structural body is connected with an outlet end of the air inlet pipe through a catalyst cover. With the art scheme, the utility model has the advantages of a low cost, a simple assembling structure, a firm connection and reliability etc. The utility model can not only reduce noise and temperature but also carry out a complete reaction of CO, HC and H2 in the waste gases with the two-way catalyst with a rapid speed at an air discharging temperature. Therefore, the harmful gases in the exhaust are eliminated, which significantly reduces environmental pollution and the exhaust reaches a European 11 discharging standard.
Description
Technical field
The utility model relates to the component on a kind of general gasoline engines, particularly a kind of silencing apparatus of 2KW general gasoline engines.
Background technique
Existing general gasoline engines silencing apparatus generally comprises and comprises front cover, housing, rear end cover, suction tude, three chambers and outlet pipes and journal stirrup is installed, as 2.5KW silencing apparatus that general gasoline engines adopts, it is connected with exhaust opening of engine by suction tude, the waste gas that motor produces circles round in three chambers of silencing apparatus, discharges by outlet pipe.Though the silencing apparatus of this structure can reach the effect that reduces noise and temperature, it does not have purification plant, and when discharging waste gas, the harmful gas in can not scavenging can not reach Europe II emission standard.
Summary of the invention
The purpose of this utility model just provides the 2.5KW general gasoline engines silencing apparatus of the band binary catalyst filter that a kind of cost is low, assembly structure simple, connection is reliable, firm, it can not only reach the effect that reduces noise and temperature, can also with the CO in the waste gas, HC, H2 fully and catalyzer under delivery temperature, react at a terrific speed, with the harmful gas in the scavenging, obviously reduce pollution, make waste gas reach the emission standard of Europe II environment.
The utility model is achieved through the following technical solutions, and promptly a kind of 2.5KW general gasoline engines silencing apparatus with the binary catalyst filter comprises front cover, housing, rear end cover and suction tude; Wherein, in housing, be separated with three chambers, in housing, be provided with the outlet pipe that is communicated with three chambers by two dividing plate branches; It is characterized in that: suction tude is provided with oxidation catalyst filter mechanism, and described oxidation catalyst filter mechanism one end is supported on the dividing plate, and the other end is connected with the end that goes out of suction tude by the catalyzer cover.
When using the utility model, earlier suction tude is connected by flange with the general gasoline engines Waste gas outlet, the general gasoline engines exhaust gas discharged is passed through oxidation catalyst filter mechanism fully, enter successively again in three chambers and circle round, discharge by outlet pipe, to reach the effect that reduces noise and temperature, because waste gas need pass through oxidation catalyst filter mechanism fully when discharging, make CO, HC in the waste gas, H2 fully and the oxidation catalyst filter medium carry out redox reaction, with the harmful gas in the scavenging, purified the gas of discharging, obviously reduced pollution environment.Described oxidation catalyst filter mechanism is the melikaria of binary catalyst.
Owing to adopted technique scheme, the utlity model has that cost is low, assembly structure is simple, be connected firmly, advantage reliably, it can not only reach the effect that reduces noise and temperature, can also with the CO in the waste gas, HC, H2 fully and the oxidation catalyst filter medium under delivery temperature, react at a terrific speed, with the harmful gas in the scavenging, obviously reduced pollution, made waste gas reach the emission standard of Europe II environment.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The utility model comprises front cover 1, housing 2, rear end cover 3 and suction tude 4 shown in Fig. 1,2,3 or 4; Wherein, in housing 2, be separated with three chambers 6, in housing, be provided with the outlet pipe 7 that is communicated with three chambers by two dividing plate 5a, 5b branches; It is characterized in that: suction tude is provided with oxidation catalyst filter mechanism, and described oxidation catalyst filter mechanism one end is supported on the dividing plate 5a, and the other end is connected with the end that goes out of suction tude by the catalyzer cover.
Shown in Fig. 1 or 2, for the ease of being connected with the 2.5kW general gasoline engines, housing 2 is provided with the journal stirrup 10 that is connected with the 2.5KW general gasoline engines.
When using the utility model, be fixed on by journal stirrup on the motor of general gasoline engines of 2.5KW, suction tude is connected by flange with the general gasoline engines Waste gas outlet, the general gasoline engines exhaust gas discharged is passed through oxidation catalyst filter mechanism fully, enter successively again in three chambers and circle round, discharge by outlet pipe, to reach the effect that reduces noise and temperature, since the suction tude of catalyzer cover welding go out end, make waste gas when discharging, need pass through oxidation catalyst filter mechanism fully, make the CO in the waste gas, HC, H2 and oxidation catalyst filter medium carry out redox reaction, with the harmful gas in the scavenging, purified the gas of discharging, obviously reduced pollution environment; Its Placement makes connection more firm, reliable for welding, and cost is low, and also Placement can be other form as required; Described oxidation catalyst filter mechanism is the melikaria of binary catalyst, it can make CO, HC in the waste gas, H2 fully and binary catalyst carry out redox reaction, with the harmful gas in the scavenging, the effect of purifying exhaust gas.
In sum, the utility model general gasoline engines of also can be used for other model only need change the shape that connects journal stirrup when producing.
