Abstract
The utility model relates to an exhaust purifying silencing apparatus for the universal petrol engine which is used to carry out the purification on the tail gas of the universal petrol engine and deal with the noise. The utility model comprises a silencer outer shell and an air inlet connecting pipe which is integrated with the outer shell and communicated with the interior of the outer shell. The interior of the silencer outer shell is provided with a diffusion pipe and an exhaust pipe. The air inlet end of the air inlet connecting pipe is welded with a flange, and the air inlet connecting pipe is inward provided with a purification honeycomb member. Under the exhaust gas purification silencer basically not changing the volume size and the structure of the prior exhaust silencer, the utility model can deal with the noise in the tail gas of the universal petrol engine discharging, as well as can deal with the harmful constituents in the tail gas discharging. The structure is simple, and the mounting and dismounting are convenient.
Description
Technical field
The utility model relates to and a kind of the general gasoline engines exhaust emissions is purified device with noise processed.
Technical background
At present, the device of handling its exhaust emissions with general gasoline engines being used to of being complementary has only exhaust silencer, and exhaust silencer can only be handled the noise of general gasoline engines exhaust emissions, to reduce the pollution of noise to environment.But the harmful components that also contain some in the general gasoline engines exhaust emissions can cause bigger pollution to environment, and exhaust silencer cuts little ice basically to the processing of these harmful matters.In order to satisfy people's requirement more and more higher to living environment, how on existing exhaust silencer basis, substantially do not changing under the prerequisite of exhaust silencer volume size and structure, a kind of noise that can handle in the exhaust emissions is provided, can handle the harmful components in the exhaust emissions again, and simple in structure, simple load and unload general gasoline engines exhaust emissions treatment device is the technical problem that present general gasoline engines industry is needed solution badly.
The model utility content
The purpose of this utility model provides a kind of simple in structure, and simple load and unload general gasoline engines exhaust purging muffler can be handled the noise in the general gasoline engines exhaust emissions, can handle the harmful components in the general gasoline engines exhaust emissions again.
General gasoline engines exhaust purging muffler described in the utility model, comprise muffler shell and the air inlet tube that is connected as one and communicates with shell with enclosure, muffler shell inside is provided with diffusing tube and outlet pipe, the inlet end of air inlet tube is welded with flange plate, is provided with the purification honeycomb structure in air inlet tube.
Described diffusing tube one end is positioned at outside the muffler shell and with the air inlet tube endoporus and overlaps, and by the flange plate end the porose back-up ring of using is installed at the air inlet tube endoporus, and described purification honeycomb structure is between this hole is with back-up ring and diffusing tube port.
Purify pottery of honeycomb structure, also metal can adopt the off-the-shelf on the market, is configured according to the length and the shape size of air inlet tube endoporus.
Flange plate with this device during use is connected with the outlet pipe of general gasoline engines, the tail gas that outlet pipe is discharged is at first through purifying honeycomb structure, after purification makes a large amount of minimizing of harmful components in the tail gas, enter muffler shell inside from diffusing tube, after eliminate the noise handling by emission by exhaust pipe in atmosphere.
Exhaust purging muffler described in the utility model is owing to have the purification honeycomb structure, can purify the harmful components in the petrol engine exhaust emissions, harmful substance contents in the tail gas is significantly reduced, and the internal structure of the structure of muffler shell inside and existing exhaust silencer is just the same, can absorb and sound energy consumption, so this exhaust purging muffler can be handled the noise in the general gasoline engines exhaust emissions, can handle the harmful components in the general gasoline engines exhaust emissions again; Because this exhaust purging muffler has just been installed the purification honeycomb structure in former exhaust silencer air inlet tube, and purifying honeycomb structure is located with back-up ring by the hole in diffusing tube port and the air inlet tube, so it is simple in structure, substantially do not change the volume size and the structure of existing exhaust silencer, and when needs are dismantled, after only exhaust purging muffler need being pulled down from petrol engine, with clamp the hole in the air inlet tube is pulled down with back-up ring, can in air inlet tube, take out purifying honeycomb structure, so its mounting or dismounting are very convenient.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the schematic representation of a kind of concrete structure of exhaust purging muffler described in the utility model;
Embodiment
As shown in Figure 1, this exhaust purging muffler comprises muffler shell 6 and the air inlet tube 4 that is welded as a whole with shell and communicates with enclosure, muffler shell 6 inside are provided with component such as diffusing tube 5 and outlet pipe 7 (owing to be known technology, so do not list one by one), diffusing tube 5 one ends are positioned at outside the muffler shell 6 and with air inlet tube 4 endoporus and overlap, with air inlet tube 4 Spielpassung, the inlet end of air inlet tube 4 is welded with flange plate 1, by flange plate 1 end the porose back-up ring 2 of using is installed at air inlet tube 4 endoporus, is provided with in the air inlet tube 4 and purifies honeycomb structure 3 between this hole is with back-up ring 2 and diffusing tube 5 ports.
Flange plate 1 with exhaust purging muffler during use is connected with the outlet pipe of general gasoline engines, the tail gas that outlet pipe is discharged is at first through purifying honeycomb structure 3, after purification makes a large amount of minimizing of harmful components in the tail gas, enter muffler shell 6 inside from diffusing tube 5, be discharged in the atmosphere by outlet pipe 7 after handling through eliminating the noise.
Claims (2)
