working principle

In the initial stage, the first solenoid valve 17 on the exhaust gas inlet cone pipe 4 and the pressure switching valve at the front end of the sprayer 9 are both closed, and the first solenoid valve 17 of the first exhaust gas inlet cone pipe 4 is opened, and the automobile Exhaust gas enters into the main body 3 through the tail gas inlet cone pipe 4, and the filter valve 6 performs net filtration on the automobile exhaust gas. 1. The pressure in the chamber on the left side rises. When the pressure rises to the pressure set to affect the exhaust, the pressure conversion valve at the front end of the sprinkler 9 is triggered, and at the same time, the first exhaust gas inlet cone pipe 4 is closed. Solenoid valve 17, open the first solenoid valve 17 of the second exhaust gas inlet cone pipe 4, the automobile exhaust gas is purified through the second purification unit, after the pressure conversion valve is opened, the sprayer 9 passes through the nozzle 11 to the filter valve 6 For cleaning, the two purification units alternately perform self-cleaning and filter vehicle exhaust.

When the sediment layer reaches a certain thickness, which affects the sedimentation speed, the cylinder 8 starts, and the scraper of the cylinder 8 pushes the sediment into the slag discharge pipe 2, and regularly discharges and recycles the sediment in the slag discharge pipe 2, and the discharged sediment can be recycled Used to craft dye blocks.

If the residence time of the washing liquid on the sedimentation filter cannot satisfy the cleaning time of the washing liquid to clean the filter, each device can be equipped with 2 sedimentation filtration areas. Then the entire evolutionary device will have 4 precipitation filter areas, and the precipitation time will be extended by 3 times, which will solve this problem.
