Description
Technical field
The utility model belongs to tail gas clean-up environmental technology field, particularly relates to a kind of purifying vehicle exhaust silencing apparatus.
Background technique
In recent years, with economic development, the owning amount of China's automobile sharply increases.The discharge of vehicle exhaust has become fastest-rising atmospheric pollution sources.The pollution problem of automobile emission becomes one of urban environment subject matter.Although there has been the technology of various control motor vehicle exhaust emission, but still can not solve the problem of the contamination particle that automobile discharges in actual use, and the long-time sustainable existence of China's haze weather needs the pollution problem solving vehicle exhaust with the least delay possible.
Summary of the invention
In order to solve the problem of motor vehicle exhaust emission dusty gas and the contamination particle existed in prior art, the utility model provides a kind of purifying vehicle exhaust silencing apparatus, can solve the noise produced when automobile exhaust pollution problem can reduce again exhaust emissions.
The technical solution of the utility model is as follows:
A kind of purifying vehicle exhaust silencing apparatus, comprise the first class purification main body and secondary purification main body that are connected by connecting screw, first class purification main body is semi-enclosed cavity, its interior central is provided with the passage of a thick filtering net formation and two passages formed by fie screen of its both sides, the inlet hole of described thick filtering net passage communicates with vehicle vent gas discharging pipe, and described fie screen passage is connected with secondary purification main body.
Fixed cover is on three filter screen supporting frames of first class purification main body one end respectively for described thick filtering net passage and fie screen passage, and the filter screen supporting frame of described centre communicates with vehicle vent gas discharging pipe.
The other end of described first class purification main body is dunnage, it is provided with between two parties a filter screen supporting frame, both sides are that tracheae is crossed in two inside, and described filter screen supporting frame and inner mistake on tracheae are equipped with air hole, are provided with half thermal baffle between described coarse filtration webmaster and fine filtering webmaster.
Be provided with the filtering layer that fie screen is formed in described secondary purification main body, described inside is crossed tracheae and is contacted with described fine filtering stratum reticulare, is provided with air outlet hole outside the fie screen filtering layer of described secondary purification main body.
The shell of described first class purification main body is provided with hanger device.
The utility model is secondary purification, filters, is adsorbed on completely on filter screen by the particulate matter in vehicle exhaust for three times, to greatly reduce in vehicle exhaust deleterious particle to the discharge amount in air, and structure is simple, replacing can be carried out and use, be worth carrying out society generalization.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model.
Fig. 2 is external structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, purifying vehicle exhaust silencing apparatus of the present utility model, comprise the first class purification main body and secondary purification main body that are connected by connecting screw 4, first class purification main body is semi-enclosed cavity, its interior central is provided with the passage of thick filtering net 3 formation and two passages formed by fie screen 2 of its both sides, the inlet hole 6 of described thick filtering net passage communicates with vehicle vent gas discharging pipe, and described fie screen passage is connected with secondary purification main body.
Fixed cover is on three filter screen supporting frames 9 of first class purification main body one end respectively for described coarse filtration webmaster and fine filtering webmaster, and the filter screen supporting frame of described centre communicates with vehicle vent gas discharging pipe.
The other end of described first class purification main body is dunnage 10, it is provided with between two parties a filter screen supporting frame 9, both sides are that tracheae 11 is crossed in two inside, and described filter screen supporting frame and inner mistake on tracheae are equipped with air hole 12, are provided with half thermal baffle 8 between described coarse filtration webmaster and fine filtering webmaster.
Be provided with the filtering layer that fie screen 2 is formed in described secondary purification main body, described inside is crossed tracheae and is contacted with described fine filtering stratum reticulare, and the fine filtering stratum reticulare peripheral hardware of described secondary purification main body has air outlet hole 7.
The shell 1 of described first class purification main body is provided with hanger device 5.
During work, vehicle exhaust enters purifying vehicle exhaust silencing apparatus by inlet hole 6, when thick filtering net 3, carry out first time filter, the passage formed due to thick filtering net 3 does not communicate with between dunnage 10, therefore tail gas must enter into fie screen 2 via coarse filtration mesh and air hole, now carry out second time to filter, the passage formed by fie screen is connected with secondary purification main body, and vehicle exhaust filters through the third time of fine filtering stratum reticulare again.Like this, after three times are filtered, the most of deleterious particle in vehicle exhaust is fully adsorbed on filter screen at different levels.Meanwhile, due to the sound absorption of filter screen, also significantly reduce noise during motor vehicle exhaust emission.
The Motor Vehicle having installed the utility model purifying vehicle exhaust silencing apparatus detects according to GB3847-2005, and the discharge value of its automobile exhaust contaminant is far smaller than limit value.
