Description
Technical field
The present invention relates to automobile exhaust gas purifying installation, specifically a kind of black cigarette purifying muffler.
Background technology
Particulate matter (PM) is one of primary air pollutant of Chinese city, is seriously detrimental to health. Research shows, distance between the corresponding residence of the sickness rate of respiratory tract disease and highway changes and changes, obviously weaken along the asthmatic patient pulmonary function of diesel powered bus and the walking of diesel fork lift trucks route, and live in the risk that the distance resident of traffic major trunk roads less than 50 meters suffer from arteriosteogenesis and increase by 60%. Diesel vehicle is granular material discharged and causes personnel to expose the most important source of risk. According to 2012 " China's Motor Vehicle Pollution Prevention annual report ", the PM of whole nation emission of diesel engine accounted for the national vehicular emission PM62.1 in more than 90%, 2011 ten thousand tons of automobile PM total emission volumn, wherein emission of diesel engine 590,000 tons. A research of 2005 shows, the diameter that land transportation produces is less than the superfine particulate matter of 300r, accounts for the 36% of total amount, and by land in traffic, the ratio of diesel vehicle contribution is 46%.
For diesel fork lift trucks, black smog fork truck discharging waste gas is emitted to choke highly seasoned when fork truck opens, fork truck noise in operating affects greatly and seriously quality product, and the black cigarette of fork truck discharge seriously affects the healthy of truck driver and Working environment, is therefore badly in need of the exhaust emissions to fork truck and controls.
Summary of the invention
It is an object of the invention to provide a kind of black cigarette purifying muffler, significantly purify the carbon soot particles in fork truck tail gas, protection Working environment.
It is an object of the invention to be achieved through the following technical solutions:
A kind of black cigarette purifying muffler, comprise muffler body, muffler body comprises housing, closure bar one, closure bar two, air intake casing and housing of giving vent to anger, housing is divided into three parts by closure bar one and closure bar two, closure bar one is near the inlet mouth of muffler body, closure bar two is near the venting port of muffler body, the two ends of air intake casing and housing of giving vent to anger all are fixed on inside closure bar one and closure bar two, air intake casing is arranged on enclosure interior of giving vent to anger, air intake casing and air inlet housing surface are provided with production well, closure bar two is provided with multiple equally distributed venting hole, closure bar one is provided with an air inlet port, venting hole is arranged on hull outside of giving vent to anger, air intake casing, give vent to anger housing, close block one and closure bar two forms spheroid carrier and fills chamber, spheroid carrier is filled and is filled spheroid carrier in chamber, the diameter of spheroid carrier is greater than the diameter of production well.
Preferably, production well annular is arranged on air intake casing (34) and housing of giving vent to anger (33) both sides.
Black cigarette purifying muffler utilizes the capillary channel interception engines tail channel black cigarette of the gap between spheroid carrier and spheroid carrier itself.
Useful effect:
That loads in the closed cavity of the closure bar one of the present invention, closure bar two, air intake casing and housing of giving vent to anger composition is spheroid carrier but not the carrier structures such as DPF, DOC, POC, as DPF wall-flow type honeycomb substrate, carbon granule latch up phenomenon can not occur and cause the engine can not normal operation, the honeycomb substrates such as DPF or POC need regular manual type take out and adopt High Temperature Furnaces Heating Apparatus heating, pressurized air blow down foreign matter algorithm, the present invention is without the need to regularly heating cleaning. Only needing the annual loss part spheroid carrier that regularly adding portion causes because of collision, specifically look service condition and check once every half a year, nominal situation lower 1 year needs add once. The present invention reduces outside huge black cigarette trap structure, more safely, add the aesthetic property of outward appearance, decrease maintenance workload, be comparatively speaking more applicable to fork truck and use.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The present invention discloses a kind of black cigarette purifying muffler, it is used for purifying engine tail gas, it is described with the embodiment of a kind of band vapor pipe and inlet pipe below, as shown in Fig. 1��Fig. 7, black cigarette purifying muffler comprises muffler body 3, inlet pipe 1, vapor pipe 5, air inlet leg 2, exhaust leg 4, stiffening plate 1 and stiffening plate 27, inlet pipe 1 and air inlet leg 2 are arranged on muffler body 3 side, vapor pipe 5 and exhaust leg 4 are arranged on another side of muffler body 3, muffler body 3 comprises housing 31, closure bar 1, closure bar 2 36, air intake casing 34 and housing 33 of giving vent to anger, housing 31 is divided into three parts by closure bar 1 and closure bar 2 36, closure bar 1 is near inlet pipe 1, closure bar 2 36 is near vapor pipe 5, the two ends of air intake casing 34 and housing 33 of giving vent to anger all are fixed on inside closure bar 1 and closure bar 2 36, it is inner that air intake casing 34 is arranged on housing 33 of giving vent to anger, air intake casing 34 and housing 33 surface of giving vent to anger are provided with production well, closure bar 2 36 is provided with multiple equally distributed venting hole 35, closure bar 1 is provided with an air inlet port, venting hole 35 is arranged on outside housing 33 of giving vent to anger, air intake casing 34 and give vent to anger and fill spheroid carrier 37 between housing 33, the diameter of spheroid carrier is greater than the diameter of production well, strong plate 1 is arranged on muffler body 3 and inlet pipe 1 junction, stiffening plate 27 is arranged on muffler body 3 and vapor pipe 5 junction.
