Embodiment 1
The cleaning device as shown in Fig. 2, air pressurized provided by the invention seeps water, including：
First air hose 300, one end connect compressed air source, and the other end is ejection end, and ejection end has nozzle, leads to
It crosses nozzle and sprays into the exhaust pipe of engine.
Urea box 900, for containing urea liquid.
Pressure vessel 100 is set in urea box 900, in the pressure vessel 100 a built-in infiltration module 200 with
The pressure vessel 100 is divided into two chambers up and down, first piston 210, bottom chamber setting second are set in upper chamber
Piston 220, first piston 210 and second piston 220 are connected by drive shaft 240, the first piston 210 and the infiltration mould
Urea chamber 230 is formed between block 200, and infiltration chamber 231 is formed between the second piston 220 and the infiltration module 200.It is preferred that
Be infiltration module 200 made by least one permeable membrane, under a certain pressure, the hydrone in urea can pass through permeable membrane
Penetrate into film another side, seepage velocity is generally related with the factors such as permeable membrane material, pressure and infiltration membrane area, can design
At required seepage velocity.In some cases, also having a small amount of urea molecule follows hydrone to be permeated together, at this time
The urea concentration being permeated should be far smaller than the urea concentration in urea box 900.
Driving spring 250, is set to the lower part of the second piston 220, and the bottom of the other end and pressure vessel 100 connects
It connects.
Wherein, the top of the pressure vessel 100 is connected to by the second air hose 110 with the first air hose 300, the urine
Have first to be open and communicated with the urea box 900 through the first check valve 270 on plain chamber 230, has on the infiltration chamber 231
Second is open and is connected to first air hose 300 through the second check valve 280 and water pipe 290.
In the above-mentioned technical solutions, be provided in urea box 900 pressure vessel 100 and other component and with the first air
Pipe 300 connects, and remnants urea is dissolved, dilutes and cleans when urea pump 400 being enable to be stopped, and does not cause to accumulate.
Further include urea pump 400 in another technical solution, is set in the urea box 900, the urea pump
400 are connected to by urea tube 410 with first air hose 300.
In another technical solution, the quantity of first check valve 270 is at least one, shown in the present embodiment
Quantity is two.
In another technical solution, the gas injection direction along first air hose 300, first air hose
300 are connected to the second air hose 110, water pipe 290 and urea tube 410 successively.
In another technical solution, further include：

The workflow of air pressurized infiltration cleaning device：For the system in normal work, air switching valve 700 is in Hou Chu
It manages and is opened under the control of system controller (DCU, figure in do not show), one compressed air (helping spray air) is through air pressure regulator
Nozzle is flowed to after 600 adjustment pressure, urea pump 400 also pumps out urea and the first air hose under DCU controls to urea tube 410
Air in 300 converges, and is then carried urea to nozzle by compressed air and sprays into the exhaust pipe of engine, while another burst of compression
Top of the air then through 110 feed pressure container 100 of the second air hose, driving first piston 210 drive second piston 220 simultaneously
It moves downward, urea in urea chamber 230 is applied with the pressure for being equal to compressed air, the first check valve 270 drives in above-mentioned pressure
Dynamic lower closing so that the hydrone in urea liquid in urea chamber 230 passes through infiltration module 200 to be permeated into infiltration chamber 231.
At this point, the driving spring 250 in pressure vessel 100 is also compressed simultaneously, and the second check valve 280 is also due to the first air
Gas pressure and second piston 220 move downward the effect of generated negative pressure and close in pipe 300.Above-mentioned infiltration process one
It is straight continue to that piston runs to lower dead center or spring is compressed into air pressure balance position until, at this point, in infiltration chamber 231
Oozing has expired water.
In engine cutoff, DCU controls air valve air switching valve 700 and closes, and to cut off air source, urea pump 400 stops
Urea is only pumped, pressure discharges in the first air hose 300, and second piston 220 drives first piston under the driving of driving spring 250
210 move upwardly together, and the water inside the chamber 231 that seeps water squeezes the second check valve 280 through water pipe under the driving of second piston 220
290 flow to the ejection end of the first air hose 300, the especially urea of urea and air meet at dissolving and dilution urea injection
(i.e. the joining place of the first air hose 300 and urea tube 410).In water after infiltration chamber 231 empties, DCU opens air switching valve
700 a period of times, such as 1 minute or so, allow air to purge water in injection pipe and residual urea clean.Complete above-mentioned cleaning
After process, DCU is again switched off air switching valve 700, and closes a whole set of aftertreatment controller system.
After the closing of aftertreatment controller system, 230 external and internal pressure of urea chamber disappears, and first piston 210 is in driving spring
Extreme higher position is maintained under 250 driving, the first check valve 270 is opened, and urea liquid stops in engine inside and outside urea chamber 230
When machine, such as night, prolonged enough exchange is obtained so that urea concentration is restored to and urea box in urea chamber 230
Urea concentration is consistent in 900, is ready for next after-treatment system startup.
