The utility model belongs to the exhaust gas post -treatment device technical field, concretely relates to a kind of exhaust gas filtration passageway with pressure relief lateral branch structure.A kind of exhaust gas filtration passageway with pressure relief lateral branch structure, including main passageway, the middle position of main passageway is equipped with detachable filter screen assembly, the filter screen separates main passageway into main passageway upper section and main passageway lower section, and is equipped with pressure relief lateral branch between main passageway upper section and main passageway lower section, and the pressure relief lateral branch is connected main passageway upper section and main passageway lower section;The inside of the pressure relief lateral branch is equipped with valve piece assembly.

The application belongs to the technical field of power generation, and particularly relates to a power supply device for automobile range extension, and more particularly to a direct-current power generation system and a working method thereof. The direct-current power generation system acquires the power of a power generation part in real time through a control module. When the power changes, the control module controls a pressurizing part to pressurize a power part cooling loop, and controls a connecting part to connect the power part cooling loop and the power generation part cooling loop, so that the high-pressure gas in the power part cooling loop enters the power generation part cooling loop, the gas pressure in the power generation part cooling loop is increased, the boiling point of the cooling liquid in the power generation part cooling loop is increased, and the cooling requirements of the power generation part and the power part are simultaneously met. When the power of the power generation part changes, the gas pressure in the power generation part cooling pipeline is increased, the boiling point of the cooling liquid therein is increased, and the cavitation effect caused by the local temperature rise and boiling of the cooling liquid due to the local eddy current caused by the power change is avoided.
