A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.

The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

A fuel cell system includes a fuel exhaust gas inlet channel for guiding a fuel exhaust gas containing liquid water discharged from a fuel cell stack to a gas liquid separator provided downstream of a humidifier in an oxygen-containing gas inlet channel. The specific gravity of the fuel exhaust gas is lighter than the specific gravity of the oxygen-containing exhaust gas. An outlet channel of the gas liquid separator includes a stirring booster having a first point and a second point positioned downstream of the first point. The second point is positioned ahead of the first point in the gravity direction.

A method for collecting particles or gaseous chemicals is provided. The method includes providing liquid to a tube of a droplet generator, heating, with a heater of the droplet generator, the tube to provide vapor to a gas flow channel inside the tube, passing a gas flow containing the particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals, and passing the droplets including the particles or gaseous chemicals to a wall of a collecting device such that the droplets including the particles or gaseous chemicals hit the wall. The temperature inside the gas flow channel is higher than a temperature inside the collecting device.

This application provides a gas-liquid separator, including a housing assembly and a plurality of first ribs. The housing assembly has an inner side wall defining a housing accommodation cavity. The housing assembly includes an inlet, a gas outlet, and a liquid outlet, the inlet. The gas outlet, and the liquid outlet are communicated with the housing accommodation cavity. The inlet is provided on the inner side wall of the housing accommodation cavity, the gas outlet is provided above the inlet, and the liquid outlet is provided below the inlet. The plurality of first ribs are arranged on the inner side wall of the housing assembly. Each of the plurality of first ribs is arranged at an angle with respect to a height direction of the housing assembly, and each of the plurality of first ribs includes a first rib windward end and a first rib leeward end. In a flow direction of a fluid entering the housing accommodation cavity from the inlet, the first rib windward end is located upstream of the first rib leeward end. In the height direction of the housing assembly, the first rib windward end is higher than the first rib leeward end. The gas-liquid separator has a compact structure, a small overall volume, and high separation efficiency.

An air intake device for a vehicle. The device includes an inlet for air, a first outlet arranged for providing air to an engine of the vehicle and a second outlet arranged for discharging liquid separated from the air provided to the first outlet, and an intermediate portion forming an air channel extending from the inlet to the first outlet and the second outlet. A bottom surface on the inside of the intermediate portion is inclined relative to a horizontal plane for directing liquid in the air channel towards the second outlet.
