The working principle of train internal combustion engine tail gas discharge processing equipment of the invention are as follows:
At work, the tail gas centralized collection that train internal combustion engine generates is transmitted to first point by exhaust collection pipe fitting 1
After first isocon 26 of stream process chamber 201, the filtrate first shunted by first in processing chamber 201 carries out the pollutant in tail gas
Precipitation adsorption, then the tail gas Jing Guo primary filtration carries out further mistake to particulate pollutants such as PM2.5 by the first strainer 28 again
Filter and absorption, and air-flow turnover chamber 202 is entered by gas port 204, when entering in air-flow turnover chamber 202 without gas, the
Filtrate in two shunting processing chambers 203 can be flow in air-flow turnover chamber 202 by the second isocon 27, turned when tail gas enters air-flow
When rolling over chamber 202, with the increase for increasing air pressure of gas, the filtrate in air-flow turnover chamber 202, which will be forced back into, flow to second point
In stream process chamber 203, then the tail gas in air-flow turnover chamber 202 will also enter the second shunting processing chamber by the second isocon 27
203, and further precipitation adsorption is carried out to the pollutant in tail gas by the filtrate in the second shunting processing chamber 203, and pass through
Also the particulate pollutants such as PM2.5 further will be filtered and be adsorbed by the second strainer 29 by the tail gas that filtrate is filtered, so
It is pumped to more than steam in water recycling bins 4 by exhausting component 3, due to by suction etc., is returned when tail gas enters water more than steam again afterwards
When receiving the gas collection case 41 in case 4, in addition the temperature of gas collection case 41 is lower than the gas directly handled tail gas certainly
Body shunts treatment box 2, therefore, the steam that tail gas is taken out of when by gas distribution treatment box 2 can in gas collection case 41 into
Row liquefaction agglomerates and is gathered in 41 bottom of gas collection case can when the liquid assembled in gas collection case 41 reaches a certain amount of
Carry out concentration emission treatment to it, the tail gas after extra steam is liquefied passes through exhaust pipe 43 again and is discharged, at this point, in tail gas
The particulate pollutants such as PM2.5 have been deposited and have adsorbed, and drain into tail gas pollution on the environment in the external world to reduce；Work as gas
When the filtrate that body shunts in treatment box 2 needs liquid feeding, then the preparation filter that will be stored in liquid reserve tank 5 can be realized by liquid feeding component
Liquid is transferred in gas distribution treatment box 2.
And in actual use, if filtrate water level is inadequate, float position will follow liquid level to decline, then when under float position
When dropping to a certain degree, floating ball will pull valve body switch by connecting line, to open valve, then the liquid in liquid reserve tank 5 is
It being shunted in treatment box 2 by 62 inflow gas of liquid-feeding tube, filtrate is replenished in time in realization, then when filtrate liquid level rises, float-level
It sets and also rises with it, then floating ball reduces the pulling force of valve body switch, is not enough to start valve body switch, then valve is closed, and stops adding
Liquid, ball-cock assembly 63 are existing product in the prior art, can select concrete model according to actual needs in practical application, and in reality
In the application of border, it is possible to use other control valves substitute ball-cock assembly 63.
Preferably, exhaust collection pipe fitting 1 includes connection valve orchid 11, the first smoke exhaust pipe 12, damping ripple in the present embodiment
