The diesel engine black smoke catalyst filtration system for the bus is mainly composed of a cylindrical air inlet cavity, a cylindrical diesel engine black smoke catalyst filter element and a cylindrical exhausting cavity. An air inlet is formed in one end of the cylindrical air inlet cavity, the other end of the cylindrical air inlet cavity is in butt joint with the one end of a cylindrical diesel engine black smoke catalyst filter, the other end of the cylindrical diesel engine black smoke catalyst filter is in butt joint with the cylindrical exhausting cavity, and an exhaust port is formed in the cylindrical exhausting cavity. The cylindrical air inlet cavity is connected with the cylindrical diesel engine black smoke catalyst filter through a hoop. A differential pressure and temperature sensor is arranged on the cylindrical diesel engine black smoke catalyst filter. By the adoption of the structural mode, the system is applied to diesel engine tail gas treatment of the bus, installed on the portion of the exhaust port of an engine and used for replacing a silencer. The system is a four-in-one system capable of treating CO, HC and PM in tail gas and achieving the partial silencing function.
Description
Technical field
The utility model relates to a kind of motor vehicle tail gas treatment device, specifically diesel motor black smoke catalyst filtration system for a kind of bus.
Background technique
It is CN201625490U that State Intellectual Property Office discloses publication number on November 10th, 2010, patent name is a kind of utility model patent of exhaust gas cleaner, the technological scheme of this patent, comprise an air reservoir of collecting tail gas, a vacuum pump that is used for aspirating tail gas in air reservoir, between air reservoir and vacuum pump, be provided with an activated carbon filter to tail gas filtering, vacuum pump exhaust port is provided with a water filter to tail gas filtering.The tail gas of air reservoir enters vacuum pump after activated carbon filter filters again, in raw material, volatile substance is by active carbon adsorption, and the escaping gas that enters vacuum pump is less, little to the lubricant pollution in vacuum pump, after water filter filtering, to environment, can pollute hardly again.But technique scheme function ratio is more single, be only physical absorption, do not there is the function of noise reduction, do not there is the ability of processing black smoke particle yet.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon monoxide CO, hydrocarbon HC and black smoke particle PM processing in tail gas, and diesel motor black smoke catalyst filtration system for the bus of part noise reduction.
For achieving the above object, the technological scheme that the utility model adopts is:
Diesel motor black smoke catalyst filtration system for bus, it mainly consists of cylindric air-inlet cavity, cylindric diesel motor black smoke catalyst filter element and cylindric exhaust cavity, one end of described cylindric air-inlet cavity is provided with suction port, the other end docks with one end of described cylindric diesel motor black smoke catalyst filter, the other end of described cylindric diesel motor black smoke catalyst filter docks with cylindric exhaust cavity, and described cylindric exhaust cavity is provided with relief opening.
Between described cylindric air-inlet cavity and cylindric diesel motor black smoke catalyst filter, adopt V-arrangement clip connected.
Between described cylindric air-inlet cavity and cylindric diesel motor black smoke catalyst filter, be provided with Drain Resistance packing ring.
Between described cylindric exhaust cavity and cylindric diesel motor black smoke catalyst filter, adopt V-arrangement clip connected.

The beneficial effects of the utility model: owing to adopting above-mentioned structural type, by this system applies in bus diesel motor vent gas treatment, be installed on engine exhaust mouth place, substitute baffler, carbon monoxide CO, hydrocarbon HC and the black smoke particle PM processing in tail gas, and the four-in-one system of part noise reduction.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is explosive view of the present utility model.
In figure: 1, cylindric air-inlet cavity; 2, cylindric diesel motor black smoke catalyst filter; 3, cylindric exhaust cavity; 4, suction port; 5, clip; 6, packing ring; 7, relief opening; 8, clip; 9, packing ring; 10, pressure reduction and temperature transducer.
Embodiment
As shown in Figure 1, diesel motor black smoke catalyst filtration system for bus, it mainly consists of cylindric air-inlet cavity 1, cylindric diesel motor black smoke catalyst filter element 2 and cylindric exhaust cavity 3, one end of described cylindric air-inlet cavity 1 is provided with suction port 4, the other end docks with one end of described cylindric diesel motor black smoke catalyst filter 2, concrete docking mode is: between cylindric air-inlet cavity 1 and cylindric diesel motor black smoke catalyst filter 2, adopt V-arrangement clip 5 to be connected, and be provided with Drain Resistance packing ring 6 between two butt ends.The other end of described cylindric diesel motor black smoke catalyst filter 2 docks with cylindric exhaust cavity 3, and described cylindric exhaust cavity 3 is provided with relief opening 7.Concrete docking mode: adopt V-arrangement clip 8 to be connected between cylindric exhaust cavity 3 and cylindric diesel motor black smoke catalyst filter 2, and be provided with Drain Resistance packing ring 9 between two butt ends.
