Abstract
The invention relates to the technical field of treatment of engine exhaust gas, in particular to an engine exhaust gas filtering device. A main body of the device consists of an inner cylinder and an outer cylinder; the inner cylinder is arranged in the outer cylinder, and is provided with an intake port and an exhaust port; the sectional area of an exhaust channel of the inner cylinder is gradually decreased in the direction from the intake port to the exhaust port; the inner cylinder is provided with a first exhaust port communicated with the exhaust port in the exhaust port; the cylinder wall of the inner cylinder is of a netty structure; an active carbon filter bin is arranged between the inner cylinder and the outer cylinder; a second exhaust port is formed in the outer cylinder; a baffle plate is arranged between the first exhaust port and the second exhaust port, and is provided with an exhaust hole; the baffle plate is provided with a filter screen in the exhaust hole; and an exchange port is formed in the outer cylinder. The device is reasonable in structure and convenient to use, and effectively prevents such problems as unsmooth exhaust of an engine and difficult starting due to exhaust gas barrier from a filter layer caused by high displacement of engine exhaust gas.
Description
Technical field
The present invention relates to motor exhaust processing technology field, be specifically related to a kind of motor exhaust defecator.
Background technology
As shown in Figure 1, in existing Tailgas purifier of engine, either monotubular or the bitubular, all include exhaustor main body 1 ' and a positioning pipe 2 ', it is provided with one or more layers filter course 3 ' in described exhaustor main body 1 ', making motor exhaust pass through to enter in air after filter course 3 ' filters, but electromotor is in real work, exhaust emissions amount is big, tail gas obstructs because of filter course 3 ', slow down its speed entering air, easily cause engine exhaust smooth, the problem such as difficulty in starting.
Summary of the invention
Therefore, it is an object of the invention to provide a kind of motor exhaust defecator, with the problem solving to propose in above-mentioned background technology.
nullFor reaching above-mentioned purpose，The present invention is achieved by the following technical solutions: a kind of motor exhaust defecator，Including exhaustor main body and a positioning pipe，Described exhaustor main body is made up of inner core and urceolus，Described inner core is located at outer barrel，Described inner core is provided with air inlet and gas outlet，The sectional area of the exhaust passage of described inner core is gradually reduced along direction, gas outlet by air inlet，Described inner core is provided with the first gas outlet being connected with gas outlet at gas outlet，Described inner core barrel is network structure，It it is activated carbon filtering cabin between described inner core and urceolus，Described urceolus is provided with the second gas outlet，Described second gas outlet barrel dliameter is more than the first gas outlet barrel dliameter，It is provided with baffle plate between described first gas outlet and the second gas outlet，Described baffle plate is provided with venthole，Described baffle plate is removable at venthole is provided with drainage screen，Described urceolus is provided with the mouth that reloads of material in changing activated carbon filtering cabin，Described positioning pipe welds with inner core at air inlet.
Further improving, the cross-sectional configuration of the exhaust passage of described inner core is circular.
Further improving, the cross-sectional configuration of the exhaust passage of described inner core is polygon.
Further improving, the cross-sectional configuration of the exhaust passage of described inner core is oval.
By using preceding solution, the invention has the beneficial effects as follows: this device is connected with engine exhaust cylinder by positioning pipe, motor exhaust is made to enter inner core, and because the sectional area of the exhaust passage of inner core is gradually reduced along direction, gas outlet by air inlet, motor exhaust is made to be partially into activated carbon filtering cabin, utilize the function that activated carbon can adsorb VOC, motor exhaust is made to reach a certain degree of purification, motor exhaust through purifying is discharged by the second gas outlet communicated with venthole, and another part tail gas is discharged from the first gas outlet.By this device, motor exhaust can be made to reach the clean-up effect of more than 30-40%.As a example by automobile tail gas pipe, drawn by experiment: for the car of 1.8L discharge capacity, this device is not installed, drawing through the detection of VOC detector, its VOC emission amount is 1.81mg/, after installing this device, its VOC emission amount is 1.19mg/, and VOC emission amount declines 34%.Further, after medium uses a period of time, its filter effect can decline, described in the mouth that reloads can change medium in time, improve the work efficiency of this device；Further, arrange at venthole and can dismantle drainage screen, preventing while activated carbon granule is taken out of by motor exhaust in activated carbon filtering cabin, can facilitate again and change drainage screen in time, prevent venthole from blocking.
Accompanying drawing explanation
Fig. 1 is the structural representation of background technology；
Fig. 2 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
With reference to Fig. 2, a kind of motor exhaust defecator as described in Figure, including an exhaustor main body and positioning pipe 3, described positioning pipe 3 is connected by locking nut 4 is fixing with engine exhaust emission cylinder 5.Described exhaustor main body is made up of inner core 1 and urceolus 2, it is internal that described inner core 1 is located at urceolus 2, described inner core 1 is provided with air inlet 11 and gas outlet 12, described positioning pipe 3 welds with inner core 1 at air inlet 11, the sectional area size of the exhaust passage of described inner core 1 and is gradually reduced along gas outlet 12 directional smoothing transition by air inlet 11, described gas outlet 12 is provided with coupled the first logical gas outlet 13, and described inner core 1 barrel is network structure, is activated carbon filtering cabin 6 between described inner core 1 and urceolus 2.Described urceolus 2 is provided with the second gas outlet 21, described second gas outlet 21 barrel dliameter is more than the first gas outlet 13 barrel dliameter, it is provided with baffle plate 7 between described first gas outlet 13 and the second gas outlet 21, described baffle plate 7 is provided with venthole 71, described baffle plate 7 71 is provided with drainage screen 8 at venthole, and described urceolus 2 is provided with the mouth 22 that reloads for changing filtering cabin 6 material.
From the above, the cross-sectional configuration of the exhaust passage of inner core 1 can do appropriately designed on demand, such as circle, polygon, ellipse, and when it is polygon, its interior angle can be fillet.
Operation principle: use locking nut 4 to be fixed on motor exhaust aiutage 5 by positioning pipe 3 in this device, the gas that electromotor is got rid of enters inner core 1 by air inlet 13, and because the cross-sectional sizes of the exhaust passage of inner core 1 is gradually reduced along direction, gas outlet 12 by air inlet 11, make motor exhaust part enter activated carbon filtering cabin 6 by netted barrel to purify, and discharged by the second gas outlet 21 communicated with venthole 71, not then directly discharging from the first gas outlet 13 by activated carbon filtering cabin 6.
