Background
With the increase of the total value of domestic production, the quantity of domestic motor vehicles is gradually increased. However, with the increase of motor vehicles, the problem of exhaust pollution caused by the motor vehicles is gradually revealed, and data show that the particulate matter emission of the motor vehicles accounts for about 30% of the total emission. The haze phenomenon seriously affects the health and social stability of residents, and the search for high-efficiency pollutant discharge technology of motor vehicles is urgent.
The particulate trap can effectively reduce the particulate matter emission of the internal combustion engine, and can be divided into a diesel particulate trap (DPF) and a gasoline particulate trap (GPF) according to the difference of the types of the adapters. Both types of particle traps are effective in reducing the particle emissions of internal combustion engines, and in technical development, it is often necessary to fill the particle trap with particles, i.e. to carry out particle loading.
Due to the continuous progress of the internal combustion engine technology, the particulate matters discharged in unit time are less, a longer loading period is needed when the particulate matters are loaded, higher loading cost is needed, the product development progress of the particle catcher product is seriously influenced, and the mass production progress of the particle catcher product is influenced. The artificial particles (simulating soot and simulating ash) are used for simulating the loading of the particles of the internal combustion engine, so that the development period can be obviously shortened, and the development cost is saved.
When the simulated particulate matter is loaded, the amount of particulates trapped in the particulate trap increases, which increases the intake pressure and changes the intake flow rate. And the deposition form of the particulate matter in the particulate trap also affects the pressure drop performance and the regeneration performance of the particulate trap.
Therefore, the development of a set of particle loading device for simulating the internal combustion engine has important significance for accelerating the application of particle catcher products, improving atmospheric pollution and protecting the health of the people.

Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a positive pressure loading device for particle traps simulating particles according to an embodiment of the present invention.
In the embodiment, the particle catcher simulated particle positive pressure loading device comprises an air compressor 1, an air supply pipeline 2, an air inlet pressure regulating valve 3, an air inlet valve 4, a particle adding port 5 and a particle mixing cavity 6, air inlet swirl pipeline 7, gas pipeline 8, the vacuum degree of admitting air table 9, function connecting pipe 10, can dismantle particle catcher 11, exhaust pipe 12 and exhaust flow control valve 13, air compressor machine 1 is linked together through air supply pipeline 2 and particulate matter hybrid chamber 6, air supply pipeline 2 is last to install admission valve 4 and the air-vent valve 3 that admits air that is used for controlling the highly-compressed air input, particulate matter hybrid chamber 6 is last to be provided with particulate matter interpolation mouth 5, the exit linkage that air supply pipeline 2 inserts in particulate matter hybrid chamber 6 has air inlet swirl pipeline 7, particulate matter hybrid chamber 6's exhaust end is linked together through gas pipeline 8 and can dismantle particle catcher 11, the exhaust end that can dismantle particle catcher 11 is connected with exhaust pipe 12.
Two ends of the detachable particle catcher 11 are respectively communicated with the gas transmission pipeline 8 and the exhaust pipeline 12 through a functional connecting pipe 10 for ensuring the uniformity of a flow field. Any one of a diffusion pipe or a contraction pipe is adopted as the functional connecting pipe 10, the functional connecting pipe 10 is connected with a pipeline which can disassemble the particle trap 11 and correspond through a connecting flange, an air inlet vacuum degree meter 9 which is used for measuring the vacuum degree of the air conveying pipe is installed on the air conveying pipe 8, and an air exhaust flow regulating valve 13 which is used for regulating the air exhaust amount is installed on the air exhausting pipe 12.
The specific loading process of the particle catcher simulation positive particulate pressure loading device is as follows: high-pressure air is provided by an air compressor 1, and the air inflow of the high-pressure air is adjusted by an air inlet pressure adjusting valve 3; particulate matter adds in particulate matter hybrid chamber 6 through particulate matter interpolation mouth 5, and when high-pressure air passed through air inlet swirl pipeline 7 for the stronger particulate matter of air current follow-up nature is raised. Aerosol airflow with particles can flow through the functional connecting pipe 10 which ensures the uniformity of the flow field, and when the airflow flows through the detachable particle catcher 11, the particles are filtered into the particle catcher, so that the particles of the particle catcher are loaded until the particles are loaded to a target value, and the particles are required to be supplemented into the particle mixing chamber 7 in the loading process. Before adding particles, the air inlet pressure regulating valve 3 is adjusted to ensure that no air leakage exists at the joint of the device, the air inlet valve 4 is a butterfly valve or a ball valve, and after the air inlet amount is adjusted, the air inlet valve 4 is closed to keep the position of the air inlet flow regulating valve unchanged. After the particles are added into the adding port and sealed, the air inlet valve 4 is opened to enable the particles to be lifted along with the high-pressure airflow, and the airflow with the concentration close to the consistent concentration and similar to the aerosol is formed. During loading, along with the gradual accumulation of particulate matters, the vacuum degree measured by the air inlet vacuum degree meter 9 is gradually reduced, and the opening degree of the exhaust flow regulating valve 13 needs to be gradually increased according to the air inlet vacuum degree value so as to ensure that the loading flow is consistent as much as possible.
